Explanation:
Diminished bone mineral density can result from inactivity. In contrast _______________ can stop if not reverse the loss of bone mineral density.
Answer: Resistance exercise
Explanation:
A decrease in the quantity of mineral in the bone can occur due to inactivity or less body movements which may be as a result of old age or a disease condition.
RESISTANCE EXERCISE is a type of training in which the muscles are subjected to work against a weight to help increase the strength of the muscles. Below are the different forms of resistance exercise:
--> Resistance bands: these bands provides resistance when they are stretched.
--> Suspension equipment: this training tool uses the body weight and gravity to form resistance.
--> Your own body weight: one can conveniently use the body weight for push ups and squats.
Generally, the resistance exercise helps to reverse the loss of bone mineral density through increasing muscle strength and tone and reducing inactivity in the muscles that led to diminished bone mineral density.

A space ship travels 3.00 ~ 10 km vertically to transport scientists from one particular station to
another. After the transportation, the captain decides to go hizontally 2.00 * 10km to visit an Orie
Calculate its:
a. Distance
b. Displacement
Answer:
a).Don't know if you meant to write 3x10^10km and 2x10^10km
I'll solve with this... If they aren't the values... You can then input the real values.
Distance = Total length traveled.
D= 3x10^10 + 2x10^10
D= 5x10^10Km
b) Displacement:
Since it went vertically... Then went horizontally in the second phase... It is forming a right angled Triangle and the Displacement would be the Hypotenuse of this triangle.
Disp.= √ (3x10^10)²+(2x10^10)²
Disp.=3.61x10^10km.

g Explain the meaning of ploidy (haploid, diploid, aneuploid etc.) and how it relates to the number of homologues of each chromosome
Answer:
The correct answer is - Ploidy is the number of sets of chromosomes in a biological cell.
Explanation:
Ploidy is the number of sets of the chromosome in a living cell. Ploidy is known for different condition such as haploid, diploid, and aneuploid, and many more depends how many homologues chromosome numbers are present in the cell.
Diploid cells are common in many organisms where one chromosome come from the mother gamete and the other from the father gamete and makes the homologues chromosomes. In diploid homologues, chromosome are 2n where n is the number of homologues of each chromosome.
In haploid there is only one set of each chromosome and mainly takes place by meiosis. In aneuploidy is the condition where the number of homologues chromosomes are not as the normal genome of the organism for example in humans instead of 46 chromosomes there 45 or 47 chromosome found.

Joe and Sam were adopted as infants into different families. They have just met and noticed how much they look alike. They are also the same age and suspect that they are twins who were separated at birth. They wish to know the truth, so have their DNA analyzed. Study this DNA fingerprint (RFLP method) and write a short essay that answers the following questions:
a. In the last column of the DNA fingerprint, what does "frequency of occurrence" mean?
b. What is the probability that Joe and Sam are not twins (i.e., that the DNA in the fingerprints could have come from unrelated men)?
Answer:
Explanation:
The missing diagram in the question is attached in the image below.
(A)
From the image below, the frequency of occurrence is shown in the last column.
The frequency of occurrence means the particular band for the entire whole population.
As an example:
1 in 15 frequency of occurrence means; ⇒ One (1) out of every fifteen (15) people has the band.
1 in 450 frequency of occurrence means; ⇒ One (1) out of every 450 people has the band.
(B)
However, Let the probability that Joe and Sam are twins be = A
and the probability that they are not twins be denoted with B;
Then;
P(B) = 1 - P(A)
where;
P(A) = Probability of specific bands appearing on the gel in every one of them
[tex]P(A) =\Big( \dfrac{1}{15}\times \dfrac{1}{15}\Big)\times \Big( \dfrac{1}{450}\times \dfrac{1}{450}\Big)\times \Big( \dfrac{1}{32}\times \dfrac{1}{32}\Big)\times \Big( \dfrac{1}{70}\times \dfrac{1}{70}\Big)[/tex]
[tex]P(A) =\Big( \dfrac{1}{225}\Big)\times \Big( \dfrac{1}{202500}\Big)\times \Big( \dfrac{1}{1024}\Big)\times \Big( \dfrac{1}{4900}\Big)[/tex]
P(A) = 4.37 × 10⁻¹⁵
∴
P(B) = 1 - P(A)
P(B) = 1 - 4.37 × 10⁻¹⁵
P(B) ≅ 1

A polygraph test is conducted, and the findings indicate that there is an 80 percent chance of deception. What does this mean for the investigation?
The suspect is guilty and should be arrested for the crime.
The suspect is probably just nervous since 80 percent is a pretty high number and usually indicates a false positive.
The suspect might be guilty, but more information is needed from other parts of the investigation.
There has been a mistake in the polygraph test, and the test should be conducted again to get better results.
Answer:
The suspect might be guilty, but more information is needed from other parts of the investigation.
Explanation:
Due process states innocent until proven guilty. Having an 80 percent chance of deception is not solid proof of anything. It does, however, bring more speculation to the table that this person is indeed guilty, but because there is no actual proof, the investigators must find more information on the matter.
Rheumatoid arthritis is commonly associated with the presence of rheumatoid factor autoantibodies in the bloodstream. This indicates that rheumatoid arthritis is likely to be a. an infective process. b. caused by bacterial infection. c. an autoimmune process. d. because of an enzymatic defect.
Answer:
The correct answer is - c. an autoimmune process
Explanation:
Rheumatoid arthritis is a disease or condition that affects the joints mainly by swollen, and painful joints. It is an autoimmune disease as the person's own immune system attacks the body.

Which type of reproduction provides organisms with the following advantages? Desirable traits can be selectively bred for in a population of organisms. More genetic diversity that might benefit individuals when environment changes.
A. Asexual reproduction
B. Sexual reproduction
Answer:
Sexual Reproduction
Explanation:
Since sexual reproduction automatically causes genetic diversity(crossing over, DNA from both parents, etc.) it produces desirable traits for organisms. Asexual reproduction does not bring in new and desirable traits and is more of a copy of the parent.

What term is used to describe the number of chromosomes in a gamete, such as
an egg cell or a sperm cell?
Answer:
The biology term, haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes
The term used to describe the number of chromosomes in a gamete would be haploid.
Gametes are usually formed by meiosis and meiosis is referred to as reductional division. When a normal diploid (2n) cell divides by meiosis, the daughter cells would have half the number of chromosomes of the parent cell. In other words, the daughter cells will have n number of chromosomes as opposed to 2n.
Cells with n chromosome numbers are generally referred to as haploid while those with normal 2n chromosome numbers are said to be diploid. Egg and sperm cells are haploid cells.

Receptor binding motifs such as RGD have highly selective recognition for cell adhesion. Outline a strategy for incorporating a cell adhesive recognition domain to a biomaterial. Address the problems surrounding domain quantity, type, and affinity in your discussion.
Answer:
Explanation:
RGD stands for Arginine Glycine Aspartate and is a three-amino-acid peptide. It is the most extensively utilized adhesive peptide for adhering diverse cell types to a variety of biomaterials. Integrins, fibrinogen, osteopontin, fibronectin, and bone sialoprotein, as well as collagens and laminins, all include an RGD primary binding domain. As a result, the synthetic (artificial) peptide RGD may bind to a wide range of integrin types. The artificial RGD retains its functioning through the sterilizing and processing processes of biomaterial creation because of its recognition advantage. This feature denotes the immune reactivity and pathogen transmission during xenograft.
Affinity can be modulated by the conformation of artificial RGD. The efficacy of RGD is also determined by the in vitro deposition of cells on the surface of the material sample.
The molecular processes unravel its effectiveness throughout its use as a scaffold foundation in in-vivo models. The fact that artificial RGD cannot work well in isolation is now a major aspect that defines its activity.
It has been discovered that cells release a variety of integrin-binding proteins that are more effective in activating integrin signalling than pure RGD. As a result, most biomaterials will bind and adsorb these proteins rather than RGD. As a result, a serum-free medium is employed in the majority of in vitro research.
As a result, biomaterials are supplied with RGD as well as quasi polymers such as polyethylene glycol to reduce the variance produced by native proteins. The addition of additional amino acids to RGD based on natural sequences can increase its biological activity, which can aid in the development of new tissues and the stimulation of cellular responses and signalling.
The amino terminal endpoint of the peptide, as well as the carboxyl group of the material surface, establish a covalent connection, which binds the peptide to just the surface of its biomaterial. Cell adhesion biomaterials are made from a variety of cell adhesion materials, including poly-L-lysine, mussels adhesive protein (MAP), and outer membrane (extracellular matrix) proteins.
Because MAPS are high in Dihydroxyphenylalanine and lysine, RGD is coupled with either of these to boost its cell adhesion capability. As a result, they can also aid in the attachment to damp or moist surfaces. It may also firmly adhere to glass, metals, and plastics. The addition of thiol groups to a peptide can also aid in its orientation and boost its stability.
The gap and density of this peptide sequence and structure on the biomaterial surface may be adjusted using a micro and nanotechnology (nanoscale patterning) method, which also improves ligand binding accuracy. Cellular reactions and cell activity are also under its control. Integrin receptors have been shown to be between 9 - 12 nm in size, therefore nanoscale surface patterning is crucial.
As a result, the above methods serve as a strategy for incorporating a cell adhesion recognition domain into a biomaterial while taking into account all of the technical intervention affecting its quantity, type, and affinity to the top layer for cell adhesion as a functioning tissue rather than a monolayer.
Homeostasis is maintained through feedback mechanisms.
a. True
b. False
Answer:
a. True
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
Homeostasis is maintained through feedback mechanisms, which are either positive or negative feedback.
During a negative feedback, a sensor and a control center in the body of a living organism maintains blood glucose to regulate blood pressure by releasing glucagon to increase blood sugar or releasing insulin to decrease blood sugar.
For a positive feedback, a sensor and a control center aids child birth by causing the uterine to contract.

Scientists observed that the populations of top-level consumers in a particular ecosystem were rapidly decreasing. Further studies revealed that there was also a decline in producer productivity. Which other changes did the scientists most likely observe in the ecosystem?
increased producer diversity
decreased population size at all levels
decreased primary consumer populations only
increased primary and secondary consumer diversity
Answer:
The correct answer is - decreased population size at all levels.
Explanation:
A decrease in the productivity of producers of an ecosystem will lead to a decrease in all other organisms of the ecosystem including top-level consumers to the bottom-level producers due to the fact that producers provide energy and food to primary consumers.
It is because they are the only organisms that convert the sunlight to usable energy and food that transfer from one trophic level to other, so if the population of producers or their productivity will decrease then there will be decreased population size at all levels.
Explain why fish would not be able to navigate their surroundings nearly as well if the light-absorbing molecules in their eyes were an order of magnitude larger or smaller than retinal.
Answer:
Fishes use a different vision mechanism than mammals and other land animals. They have rods and cone photoreceptors to see the colorful visions and adjust their focal point by moving the lens closer to or away from their retina.
In the water bodies, a difference in the amount of light moves with the depth because water absorbs the light and this change occurs due to the optical nature of water.
The light bounces once it back in the retina, leads to the gain of the small packets of energy of light a second chance to be trapped by photoreceptors. However, vision remains blurry. The changes and distortion of the light-absorbing molecules present in the eyes of fishes make it tough to perceive a clear vision.
