Explain why a rock pocket mouse color influence its overall fitness. Remember that "fitness" is defined by an organisms ability

to survive and produce offspring in its environment
Biology

levacccp [35]2 years ago

Answer:

The rock pocket mice rely on their fur color for camouflage. So, on the tan sand more light colored mice will survive because they blend in and on the dark lava rock more dark colored mice will survive and the allele for dark fur will be passed on to their offspring

When mammals get an infection, their internal body temperature often rises 2 to 3 degrees Celsius. The body gets the energy it n
Paladinen [302]

Answer:

The correct answer is increasing the rate of cellular respiration in mitochondria.

Explanation:

In mammals like humans, the infection causes a rise or hike in the body temperature of an individual up to 2 - 3 degrees Celsius. Infection results in thermoregulation strategies control by the hypothalamus, of the host by immune system transmitted integration signals, hormonal and neuron lead and increase in metabolic reactions by the increase the rate of the cellular respiration takes place in the mitochondria and that elevate body temperature. Mitochondria releases energy in the form of ATP that helps in body temperature as it is an exothermic reaction.

The correct answer is increasing the rate of cellular respiration in mitochondria.

Suppose that Gene B occurs in a sea turtle gene pool where the frequency of the B1 allele is 0.5 and the frequency of the B2 all
disa [49]

Answer:

Frequency of the B3 allele = 0.1

Explanation:

The allele frequencies in a given population remain constant which means that every generation will have the same gene pool across the generations. As per Hardy Weinberg’s first equilibrium equation, the sum of frequency of all the alleles at a given locus is equal to one  

Thus, if "p" represents the frequency of B1 allele and "q" represents the frequency of B2 allele and "r" represents the allele for B3 allele. Then, sum or "p", "q" and "r" is equal to one.

p+q+r = 1\\

Substituting the given values, we get -

0.5 + 0.4 + r = 1\\0.9 + r = 1\\r = 1-0.9\\r = 0.1

Advantage amoeba has over a cell of a lizard in relations to their levels of organism
nignag [31]

Amoebas are single-celled organisms, which means that they are composed of just one cell. Each amoeba is a cell capable of performing all living functions by itself. They can reproduce asexually. They are protozoans with no fixed shape. Most have no hard parts and look like blobs of jelly.

Enhancerless GFP reporter constructs used in research conducted in mice contain a generic mouse gene promoter (TATA box) followe
balandron [24]

Answer:

the reporter gene can randomly insert near to an enhancer sequence which can induce its expression

Explanation

Enhancers are genetic sequences capable of activating gene expression by binding to specific proteins (e.g., transcription factors). Enhancers can regulate the expression of nearby genes located thousands of nucleotides away, i.e., over several kilobases away. In the human genome, it is well known that enhancers are scattered across the 98% of the genome. In this case, it is expected that the reporter GFP gene construct is randomly inserted near an enhancer sequence (a 10% chance of insertion), thereby being regulated by that enhancer.
