Answers

Answer 1

A. Repair systems that target a single type of damage in DNA and repair only that type of damage are called specific repair systems.

B. Repair systems that use a single repair mechanism to repair multiple types of damage in DNA are called nonspecific repair systems.

C. A system that only repairs thymine dimers is photo repair.

D. In excision repair, the damaged section of one DNA strand is removed and replaced with new DNA that is synthesized using the undamaged strand as a template.

E. Cells can repair the damage that produces breaks in DNA using enzymes related to those involved in recombination during meiosis.

Specific repair systems target and repair a single type of DNA damage, such as photo repair which repairs only thymine dimers caused by UV light. In contrast, general repair systems use a single mechanism to repair multiple types of DNA damage, such as excision repair which can repair damage caused by chemical exposure and radiation.

Photorepair is a specific repair system that repairs thymine dimers in DNA caused by UV light. The process involves using energy from visible light to break the bonds between the thymine molecules and return them to their normal state. Excision repair is a general repair system that involves removing a damaged section of DNA and synthesizing a new, undamaged strand using the complementary strand as a template.

Cells can also repair the damage that produces breaks in DNA using enzymes related to those involved in recombination during meiosis. This process, known as homologous recombination, involves exchanging genetic material between two homologous chromosomes to repair a break. This mechanism is highly regulated to prevent errors and ensure proper repair of DNA damage.

Ronald observes a sparrow's nest in a shrub outside his home. The table below describes his findings.
Week
Observations
1
Six eggs were laid in the nest.
3
Five eggs hatched, and one egg did not hatch.
One of the chicks disappeared.
7
Three of the chicks learned to fly, and another one disappeared.
What part of natural selection did Ronald observe?
adaptation
overproduction
selection
variation

Answers

Answer:

B. Overproduction

Explanation:

Overproduction is one of the main part of natural selection whereby an organism reproduces more offspring, of which only a few would be able to survive given the environmental condition amd factors that would be against the survival of the offspring to maturity.

From Ronald observation, we can see that the bird produces more eggs than would survive. Only 3 of the chicks survived.

The allelic frequency for pointed ears is 75 (75%).
The allelic frequency for rounded ears is 1.0.
The allelic frequency for pointed ears is 0.5 (50%).

Answers

Answer:

The allelic frequency for pointed ears is 0.5 (50%).

Explanation:

The frequency of alleles in a population must add up to 1 (100%).

The allelic frequency for pointed ears is 0.5 (50%).

What is allelic frequency ?

The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.

What is the difference between gene frequency and allele frequency?

Gene frequency, which more or less refers to the allele frequency, is the measurement where the number of repeats of the same allele is measured over a certain period of time.

What are ethical concerns in using animals for research?

Select all that apply.

Animals cannot consent to being used in experiments.
Animals are ideal biological models for experiments
Many animals can be studied at one time.
Some animals may have adverse reactions.

Answers

Answer: Animals cannot consent to being used in experiments.

Explanation:

Animals are not suitable options for the biological research as they are getting extinct and their population size is getting decreased. Option A is correct.

What are extinct species ?

These are the species that are getting diminished from planet because of certain factors such as loss of habitat and many other crucial factors that affecting their growth.

Animals can not be used in the biological research as  they are not able to speak the language which is understood by humans and ideally it is not right to do dissection over living beings.

Animals earlier were definitely considered for the experiment but the awareness of ethics and sensitivity of the issues is bringing down the ban on the animal crimes along with the lab research.

Ethical concerns are as well that without God's permission it is not right to harm the living beings.

Therefore, option B is correct.

Answers

Answer:

two tectonic plates slide past each other underwater, causing a large movement of water large ocean waves form .large ocean waves move in all directions away from the shifting plates .large ocean waves slow down and increase in height as they reach the coast

Explanation:

Tsunamis are initiated underwater and usually happen as a result of underwater earthquakes which can be initiated when tectonic plates slide past each other.

This causes a large movement of water such that large waves form and move away in al directions from the source. As these waves approach the shore they slow down speed but this only increases their height such that when they make landfall the effect could be devastating.
