List the three pairs of bones that make up the pelvis in the adult animal
Answer:
the ilium, ischium, and pubis.
Explanation:
In adults, the hip bones, or coxal bones are formed by the fusion of three pairs of bones: the ilium, ischium, and pubis.
Which hypothesis do the similarities in the bone arrangements support?
a. These organisms are members of the same species.
b. These organisms may have descended from the same ancestor.
c. These organisms have adaptations to survive in different environments.
d. These organisms all contain the same genetic information.
Answer:
B
Explanation:
A similarity in the arrangement of bones in organisms can be hypothesized to be an indication of the organisms descending from the same ancestor.
The similarity in the arrangement of bone in different organisms is one of the morphological evidence used to support the theory of organic evolution which says that all living organisms are of the same descent with modification from common ancestors.
The similarity in the arrangement of bones falls under homology. Homologous organs are similar in structures but different in functions. For example, the pentadactyl limbs of vertebrates. Mammals, birds, reptiles, and amphibians all have limbs that are built on a five-digit plan but the functions of the limb vary within and among different groups of vertebrates.

The color of a light wave is determined by its wavelength. On the COLOR tab, slowly drag the Light wavelength slider back and forth and observe the effect on oxygen production. How does the color of light affect the rate of photosynthesis
Answer:
The color of light determines how effective chlorophyll pigment will be at absorbing light.
Explanation:
Photosynthesis is a metabolic process that requires light, which is an electromagnetic radiation. Light on the electromagnetic spectrum is determined by wavelength. Each region/color of light occurs at a specific wavelength.
Hence, chlorophyll pigment, which is the major photosynthetic pigment effectively absorbs blue and red light in the visible light region of the electromagnetic spectrum. Hence, the rate of photosynthesis will be affected negatively if the color of light is not the one stated above.
[FW.04H]A single computer microchip uses 10 gallons of water during its manufacture. A group of people suggested that the use of computers should be reduced to help conserve water. Which of these is the best alternative method to conserve water in manufacturing microchips?
Reduce the size of microchips.
Use graywater to manufacture microchips.
Collect rainwater and use it to make microchips.
Research ways to reduce water waste in making microchips.
Answer:
Option D, Research ways to reduce water waste in making microchips
Explanation:
The best way to conserve any natural resource is to conserve it at the source point and further make it apt for re use.
If the water waste is microchips is reduced then gallons of water will be saved. Also, devising engineering mechanism to reuse water in chip manufacturing industry will further reduce the water waste.
Hence, option D is correct
What gametes are produced by the following organisms:_______.
a. Genotype YyRr, if Y and R are on different chromosomes
b. Genotype YyRr, if dominant Y and R are on the same chromosome, no crossing over
c. Genotype YyRr, if dominant Y and recessive r are on the same chromosome, no crossing over
d. Genotype YyRr, if dominant Y and R are on the same chromosome, 50% crossing over
Answer:
The correct answer would be -
1- YR, Yr, yR and yr.
2. Yr, yR
3. YR, yr
4. YR, Yr, yR & yr
Explanation:
A mature male or female haploid germ cell that fuses with another gamete of the opposite sex during the process of fertilization to make a zygote in sexual reproduction.
The law of Independent Assortment presented by Mendel says that alleles for different traits are passed and assort independently of one another in the gametes.
1. If Y and R on different chromosomes then they will produce four gametes and assort independently - YR, Yr, yR & yr.
2) If Y and R on the same chromosomes and no crossing over occurs then they will produce only two gametes as Y and R will not come together - Yr & yR.
3). if dominant Y and recessive r are on the same chromosome, no crossing over then only two gametes will form as Y and r will not assort together - YR & yr.
4). if dominant Y and R are on the same chromosome, 50% crossing over produces 4 types of gametes, YR, Yr, yR & yr.
Which best explains why water quality standards have been created to ensure heavy metals in water are kept to a minimum?
O A. Heavy metals are linked to toxicities in humans and large amounts of heavy metals should not be consumed.
OB. Heavy metals can stain ceramic surfaces in homes and cost the homeowners hundreds in repairs.
OC. Heavy metals can cause discoloration of water and can cause a strong unpleasant odor.
O D. Heavy metals can corrode pipes and cause problems with internal plumbing.
its OB because if you read it says it praticly
Heavy metals are harmful and should not be consumed in large amounts. Therefore, option (A) is correct.
What are harmful effects of heavy metal in water?The flow of groundwater and surface water, as well as seepage and runoff from the surface, can introduce heavy metals into private wells. People who consume significant quantities of heavy metals put themselves at risk for acute and chronic toxicity, as well as anemia, cancer, and damage to their liver, kidneys, and intestines.
Heavy metals in water are usually treated using methods like chemical precipitation, flotation, adsorption, ion exchange, and electrochemical deposition. Most of the time, heavy metals are taken out of inorganic effluent by a process called chemical precipitation.

Mutations result in changes to genotype that can result in changes in phenotype. Explain how a mutation causes a change in the genotype of an organism AND may result in a change in the phenotype of an organism.
Answer:
A mutation can alter the structure/function of a particular protein, thereby also altering the phenotype resulting from this new variant
Explanation:
A mutation can be defined as a genetic change in the genome of an organism. Some mutations are capable of modifying the expression and/or structure of the proteins, while other mutations (known as silent mutations) have no effect on the resulting proteins. When mutations occur within the gene region encoding a protein (i.e., exons), they are potentially capable of producing a faulty protein. For example, a mutation can alter the Open Reading Frame (ORF) of the resulting protein, thereby inactivating it. The mutations that alter the structure and/or function of the protein can also alter the resulting phenotype associated with the expression of this protein. For example, a mutation within a gene that encodes a key enzyme can potentially alter the binding site of the protein, so the resulting mutated enzyme cannot bind to the substrate anymore. In consequence, this mutation alters the phenotype of the individual who is not more able to carry out the metabolic reaction catalyzed by the faulty enzyme.

Mendel used over 28,000 pea plants in his experiment. How does this large
sample size make his results more reliable?
Answer with Explanation:
The large sample size allowed Gregor Mendel to make comparisons quantitatively. The "margin of error" is narrower and it allowed him to detect statistically significant results through its statistical power. Large sample sizes have a greater statistical power. However, it takes a lot of time, effort and money. Mendel was very persistent and had the driving force. This allowed him to develop the "Three Principles of Inheritance."
A smaller sample size doesn't give a significant difference because the samples are quite random. This has a tendency to mask the result.
Write each phrase into the appropriate category.
a. cross between organisms that are the same for two traits
b. the cross was performed by Mendel using pure-breeding lines
c. cross between organisms that differ for three traits

dihybrid cross trihybrid cross both none
Answer:
a. none
b dihybrid and trihybrid crosses (both)
c. trihybrid cross
d. none
e. dihybrid cross
Explanation:
A dihybrid cross can be defined as a mating experiment between two different varieties/lines that differ in two observed phenotypic traits, while a trihybrid cross is a cross between two varieties/lines that differ in three traits. For example, Mendel crossed two pea plants that differed in seed color (yellow and green) and seed shape (wrinkled and round). Mendel's experiments consisted of dihybrid and trihybrid crosses for different phenotypic traits. From these mating experiments, he observed dihybrid F1 plants produced 9:3:3:1 ratio of phenotypes in the F2 generation.
A characteristic of living organisms is their ability to maintain internal balance.
Maintaining internal balance inside the body is
Answer:
Homeostasis.
Explanation:
A characteristic of living organisms is their ability to maintain internal balance. Therefore, maintaining internal balance inside the body is known as homeostasis.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.
For example, if a person becomes infected with a pathogen such as a virus. The internal stimulus that most likely takes place in order for their body to maintain homeostasis is that their core temperature increases. This is because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).

false
O true
HURRRRYYYp
Answer:
The first statement is true, while the second statement is false.
Explanation:
Every living organism needs a particular amount of food in order to be able to survive. Each species though has its own different requirements, and there are great variations that occur because of size, lifestyle, is the organism cold-blooded or warm-blooded, etc.
In this case, we have to examples. In the first one, a single mouse needs 4 square meters of grass in order to stay healthy. In order to get the amount of grass needed for fifty mice, we just need to multiply the number of mice by the amount of grass needed for one of them:
50 x 4 = 200
We got 200, meaning that 200 square meters of grass will support a population of 50 mice.
In the other case, a single snake needs 10 mice in order to stay healthy. To get a result how many mice are needed for 10 snakes, again we just need to multiply the number of snakes by the number of mice a single snake needs:
10 x 10 = 100
We got 100, meaning that 10 snakes need 100 mice in order to stay healthy.

How many factors does a scientist want to differ between the experimental and control groups?
A) 2
B) 0
C) 1
D) 3
Answer:
C
Explanation:
The experimental and control group differ by only one factor for a scientist, and that is the independent variable.
A scientist will always try to isolate the effects that are due to a variable and keep every other variable constant. The variable that is manipulated in order to measure its effect is known as the independent variable. A control group usually forms the basis for measuring the effects of the independent variable. While the independent variable is varied in experimental groups, it kept at the zero level for the control group.
The correct option is, therefore, C.

A disease infects an organism, causing the organism's cells to have less chloroplasts. How will the organism be impacted by having less chloroplasts?
The organism will have less chlorophy reducing its ability to collect energy
The organism will have less cellulose, reducing its ability to remove waste
The organism will absorb less oxygen, reducing its ability to produce sugar
The organism will absorb less water, reducing its ability to create DNA
Answer:
the organism will have less chlorophyll
Explanation:
chloroplasts contain chlorophyll
Chlorophyll is a green pigment, without it a plant is discolored meaning it lacks of chlorophyll. Less photosynthesis would occur, and less glucose is made as a result. There is less energy released for growth as glucose is needed for respiration.
