13. How does the protein p53 act as a negative regulator?

Answers

Answer 1

Answer:

The major negative regulator of p53 is the Mdm2 proto-oncogene. Mdm2 is transcriptionally induced by p53, thus p53 triggers its own destruction through a negative feedback loop. This feedback loop leads to oscillations in the expression of both proteins following DNA damage.

which are distasteful or toxic in response to an herbivore attack. Which of these is the LEAST correction description of the plant system interactions involved?

A. Carbon dioxide diffuses through stoma into leaf tissues, where it is fixed into organic compounds
which may serve as building blocks for chemical defenses.

B. Root systems obtain water and key minerals from the soil where they are transported to the affected site.

C. Shoot systems carry carbon dioxide, water and nutrients from leaves directly to the affected
plant part, where chemical defense molecules are produced.

Explanation:

Answer:

Explanation:

Mechanical Defenses

The first line of defense in plants is an intact and impenetrable barrier composed of bark and a waxy cuticle. Both protect plants against herbivores. Other adaptations against herbivores include hard shells, thorns (modified branches), and spines (modified leaves). They discourage animals by causing physical damage or by inducing rashes and allergic reactions. Some Acacia tree species have developed mutualistic relationships with ant colonies: they offer the ants shelter in their hollow thorns in exchange for the ants’ defense of the tree’s leaves.

The arctic fox is uniquely adapted to its environment with white fur for camouflage, a small nose and ears and warm coat to prevent heat loss and strong paws for running and hunting. Which statement best describes how the arctic fox population may have adapted to its environment over time?
Choose the correct answer.


Foxes were bred to meet human needs for white fur.

Foxes developed smaller ears and noses in response to their cold climate. They were able to survive and pass this trait on to their offspring.

Foxes changed their fur to white to hide from predators and disguise themselves from their prey. They were able to survive and pass this trait on to their offspring.

Variation existed in the traits of the fox population. Foxes with smaller ears and noses were able to stay warmer and were more likely to survive and reproduce to pass their genes on to offspring. Over time, the fox population showed a shift to smaller ears and noses.

a. animals produce oxygen used by plants for photosynthesis.
b. animals produce oxygen used by plants for respiration.
c. animals produce carbon dioxide used by plants for photosynthesis.
d. animals produce carbon dioxide used by plants for respiration.

Answers

Answer:

C

Explanation:

Animals produce carbon dioxide as a byproduct of cellular respiration. Plants use the carbon dioxide through photosynthesis to produce oxygen.

Animals produce carbon dioxide as a byproduct of cellular respiration. Plants use the carbon dioxide through photosynthesis to produce oxygen, thus, animals produce carbon dioxide used by plants for photosynthesis.

What is the oxygen and carbon dioxide cycle called?

Photosynthesis is the method by which plants use sunlight, water, and carbon dioxide to make oxygen and energy in the form of sugar.

Thus, option "C" is correct, animals produce carbon dioxide used by plants for photosynthesis.

Which approach would be least helpful in determining genetic differences between species?

Answers

Answer:

the least helpful would be a straight up guess, the best way would be to to back in the history of that species and study how they lived and survived and reproduced and all that stuff

Explanation:

Comparing physical characteristics between species is not a reliable method for determining genetic differences because many physical traits are influenced by environmental factors and may not necessarily reflect the underlying genetic differences between species.

What is an example of this ?

For example, two species may have different fur colors or patterns, but this difference may be due to environmental factors such as exposure to different types of light rather than genetic differences.

In contrast, analyzing DNA sequences can provide a more precise and objective way to identify genetic differences between species. By comparing the DNA sequences of different species, scientists can identify variations in genes and regulatory regions that may be responsible for differences in traits or behaviors between species.

This approach can also reveal the evolutionary relationships between species and provide insights into how genetic variation has driven the diversification of life on Earth.

Therefore, Advances in genomic technologies have made it increasingly feasible to sequence and compare the genomes of diverse species. Comparative genomics has already revealed many insights into the genetic basis of traits such as human disease susceptibility, adaptation to environmental challenges, and the evolution of complex traits such as intelligence and social behavior.

A) Interactions of the circulatory and immune systems create an increased blood flow and immune cell metabolism, which causes redness and swelling. B) Interactions of the respiratory and immune systems create an increased breathing rate and immune cell metabolism, which can lead to redness and swelling. C) Interactions between the immune system and digestive system increase the digestive enzyme activity at the site of the infection, which leads to redness and swelling.

The statement that best describes the symptoms of redness and swelling at the site of a splinter after its removal is the interactions of the circulatory and immune systems create an increased blood flow and immune cell metabolism, which causes redness and swelling.

What do you mean by Pathogen?

Pathogens may be defined as microorganisms that are responsible for the causation of various diseases, infections, and disorders.

When a splinter attacks your body, your body identifies that it is a foreign substance, it will activate the immune response through the skin and causes redness in association with the circulatory system by increasing the blood flow.
