Answer:
Activating genes with their own promoter, dysregulating them.
Explanation:
Transposable Elements (TEs), also known as transposons, mobile elements or jumping genes, are genetic sequences able to move within a host genome by a mechanism called 'transposition'. As a result of their transposition, TEs may cause diverse genetic alterations and disrupt host gene expression at the integration site. Some of the most common deleterious effects induced by TE transposition include, among others, insertional mutagenesis, duplicated sequences, chromosome translocations, etc. Moreover, although it has been shown that some types of TEs contain transcription factor binding sites (as well as cis-regulatory motifs), they don't have promoter sequences that activate host gene expression upon TE transposition.

Do humans have an open or closed circulatory system? Explain.
Answer:
Explanation:
Organisms have different forms of circulatory systems. Humans have a closed circulatory system, while many mollusks and other invertebrates have an open system. In a closed circulatory system, blood is enclosed within blood vessels.
Goats can either be polled or horned. The pulled, or no horn, trait (P) is dominant to the horned (p) trait. Another trait in goats are wattles, which are hair covered structures on their necks. Even though most goats do not have wattles, having wattles (W) is dominant to not having wattles (w). A breeder crosses a polled, wattled male goat with a polled, wattled female goat. Some of the offspring have horns and no wattles. Perform a cross of the parental genotypes to find the phenotypic ratios of the offspring.
Answer:
Pulled and wattled = 9/16
Pulled and no wattle = 3/16
horned and wattled = 3/16
horned and no wattle = 1/16
Explanation:
Pulled = P, Horned = p
Wattled = W, no wattle = w
Polled, wattle goats = P_W_
Since they produced offspring with horns and no wattles (ppww), it means both parents have the recessive allele for each trait. Hence, they are both heterozygotes with PpWw as genotypes.
PpWw x PpWw
Genotypes ratio of the offspring:
P_W_ - 9/16
P_ww - 3/16
ppW_ - 3/16
ppww - 1/16
Phenotype ratio of the offspring:
Pulled and wattled = 9/16
Pulled and no wattle = 3/16
horned and wattled = 3/16
horned and no wattle = 1/16
(See the attached image for the Punnet's square)
Some alleles of a gene are dominant to others masking the effect this other alleles.
The polled, or no horn, trait (P) is dominant to the horned (p) trait.
Having wattles (W) is dominant to not having wattles (w).
A breeder crosses a polled, wattled male goat with a polled, wattled female goat.
The phenotypic and genotypic ratios would be
Polled and wattled = P_W_ = 9/16Polled with no wattle = P_ww = 3/16horned and wattled = ppW_ = 3/16horned with no wattle = pwpw = 1/16Parent genotype --- polled, wattled male and female goat -- P_W_
As the cross produced offspring with horns and no wattles (ppww), it shows both parents have the recessive allele for each trait.
Hence, they are both heterozygotes with PpWw for the traits.
Parent genotypes: PpWw x PpWw
PW Pw pW pw PW Pw pW pw
PW Pw pW pw
PW PPWW PPWw PpWW PpWw
Pw PPWw PPww PpWw Ppww

How did economics delay scientists' first attempts for conservation in each story?
The correct answer to this question is the following.
Unfortunately, your question is incomplete. You did not attach the two stories. So we do not know what the topic is. You also forgot to attach a link or the title of these stories.
However, trying to help you we did some deep research and can comment on the following.
There are two stories about Conservation Activity. One is about "Using Forest Wisely" and the other is about "Community Conservation."
If that is the case, we can say that the economics delay scientists' first attempts for conservation affect the conservation study and the environment in that cutting those trees for economic purposes directly impact the wildlife and nature of the region.
Trees are the sentient beings that produce the oxygen human beings need to breathe fresh air. They clean the air because trees "breathe" carbon dioxide. The uncontrolled cutting down of trees could affect because resources could be scarce, increasing prices of goods.
One of the stories refers to the case of gorillas in places such as Rwanda or Uganda, risking the habitat of these animals and the entire environment of those forests, which also results in affecting the economy of the places.

Explanation:
When sufficient heat is applied, double-stranded DNA denatures into two single-stranded molecules as the heat breaks all of the hydrogen bonds. In an experiment, molecules of single-stranded DNA from species X are separately hybridized with supoosedly homologous single-stranded DNA molecules from five species (A-E). The hybridized DNAs are then heated, and the temperature at which complete denaturation occurs is recorded. Based on the data, which species is probably most closely related to species X
Answer and Explanation:
When sufficient heat is applied, DNA unwinds, and the hydrogen bonds that grip the strands together weaken and break. The process of breakdown of double-stranded DNA into single strands is called DNA denaturing. The temperature at which double-stranded DNA is half denatured is termed as Tm (melting temperature). By the absorbance of the DNA solution, the amount of strand melting is measured at 260nm. At this wavelength, nucleic acids absorb light. When DNA strands come together, the proximity of the bases in the DNA strands reduces some absorbance. When the DNA strands separate, the absorbance rises 30% to 40%, and quenching of the absorbance disappears. This is known as hyperchromicity. By using DNA denaturation, the sequence difference between the two DNA sequences can also be detected. When double-strand DNA is heated, it denatured into a single-stranded state. The mixture is cooled to allow the strands to re-hybridize. Hybrid molecules are formed among related sequences.
Plants and animals are multicellular organisms?
Which statement best describes the difference between them and other organisms?
(A) they have organelles in each cell perform function to keep the cell alive
(B) they are made of many specialized cells types that perform specific functions to keep the entire organism alive
(C) the cells that make them up are larger than cells that make up bacteria, yeast, or amoeba
(D) they can all use socialized cells to make their own food by capturing the suns energy, other organisms cannot do this
Answer:
B) they are made of many specialized cells types that perform specific functions to keep the entire organism alive
Explanation:
A multicellular organisms are organisms that possess many cells in its body system. As stated in this question, plants and animals fall under this multicellular category. These cells begin to specialize in function as they divide through a process called CELL DIFFERENTIATION.
In comparison with the number of cells of other organisms, which are unicellular (one cell), multicellular organisms are made of many specialized cells types that perform specific functions to keep the entire organism alive whereas in unicellular organisms, only the organelles in one cell performs the function.
What is a type of reaction that occurs when you burn something? (combine it with oxygen)
Answer:
Combustion is the scientific word for burning. In a combustion reaction, a substance reacts with oxygen from the air. Combustion reactions happen at high temperatures, and transfer energy to the surroundings as light and heat. This is why you see flames when things burn.
Answer:
A substance combines with oxygen and releases energy in the form of heat and light.
combustion is the best type of chemical reaction.
Explanation:
When a substance combines with oxygen and energy is emitted in the form of heat and light, this process is called combustion.
There are two types of combustion.
1) Complete Combustion : It is a type of combustion in which fuel is quickly react with high amount of oxygen forming carbondioxide, water, heat and light.
2) Incomplete combustion : It is a type of combustion in which fuel is react with low amount of oxygen forming carbonmonoxide, carbon and water.
Explanation: Combustion is a reaction in which a substance (a fuel) reacts with oxygen to produce heat energy. Another name for combustion is burning. Combustion can be complete or incomplete: complete combustion takes place in the presence of unlimited supply of oxygen in which the substance is completely oxidized leaving water and carbon dioxide as by-products. Incomplete combustion occurs in the presence of limited quantity of oxygen in which the substance is not completely oxidized. The byproducts are carbon monoxide and soot.

You immediately step back because the spinal cord sends a command via the _______ - Word Answer Type your answer here to your leg muscles, which are acting as the ________ - Word Answer
Answer:
1. Receptor (nociceptor).
2. Afferent neurons.
3. Spinal cord.
4. Motor neurons.
5. Efferent neuron (effector).
Explanation:
In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
In this scenario, you accidentally stub your toe on a chair when walking in a darkened room. A receptor (nociceptor) relays this information by sensory nerves in the afferent neurons to the spinal cord, which in this case is the spinal cord. You immediately step back because the spinal cord sends a command via the motor neurons to your leg muscles, which are acting as the efferent neuron (effector).

5. 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:
a) YR, Yr, yR, yr
b) YR, yr
c) Yr, yR
d) YR, yr, Yr, yR
Explanation:
Before gametes are formed, during anaphase sister chromatids separate and migrate to the poles. Following the low of segregation and independent assortment, alleles from the same trait and from different traits separate independently from each other. During this separation, there might be different gene combinations according to their position in the chromosome, the occurrence of crossing over, and the destiny of each chromatid.
a. Genotype YyRr, if Y and R are on different chromosomes
Genes are located in two different chromosomes, which means that there might be four possible gametes.
YR, Yr, yR, yrb. Genotype YyRr, if dominant Y and R are on the same chromosome, no crossing over
Genes are located in the same chromosome, which means that there might be two possible gametes.
YRyrc. Genotype YyRr, if dominant Y and recessive r are on the same chromosome, no crossing over
Genes are located in the same chromosome, which means that there might be two possible gametes.
YryRd. Genotype YyRr, if dominant Y and R are on the same chromosome, 50% crossing over
The fact that there is 50% crossing over means that these genes are not linked. There are four possible gametes

the offspring had black fur only. Which parental cross was most likely responsible for the percentages of offspring fur color
the scientist found?
A. BW x WW
B. BW x BW
C. BB x WW
D. BW x BB
Answer:A. BW x BB
Explanation:
The parental cross that was most likely responsible for the percentages of offspring fur color, the scientist found, BW x WW. The correct option is A.
What is crossing?The exchange of genetic material between non-sister chromatids of homologous chromosomes occurs during crossing over, an enzyme-mediated process. It happens during meiotic prophase I's pachytene stage.
When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place.
Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up. The same genes may be present on the two chromosomes in different versions.
Therefore, the correct option is A. BW x WW is the result of the crossing over of offspring for a mated pair of hamsters.
