Which repair process in e. Coli uses visible light to repair thymine dimers?.

Answers

Answer 1

Answer:

photoreactivation repair

Explanation:

Photoreactivation utilizes the enzyme photolyase to break the bonds formed during pyrimidine dimerization. A thymine dimer produced by UV irradiation is bound by photolyase. Visible light energy is absorbed by photolyase and is redirected to break the bonds forming the dimer.

In addition to bacteria, this DNA repair mechanism is also found in single-celled eukaryotes, plants, and some animals such as Drosophila.

Non-living physical and chemical elements in the ecosystem are referred to as abiotic factors. Typically, abiotic resources are obtained from the lithosphere, hydrosphere, and atmosphere [e.g. water, aer, soil, sunlight, and minerals].

Biotic factors are organisms that are alive or were onse alive in an ecosystem. These are obtained from the biosphere and have the ability to reproduce [animals, birds, plants, fungi, and other identical organisms].

Why is it important to design field studies that will not make wild animals associate humans with food?

Answers

Bc wild animal will kill human and that bad. Implementing studies that condition wild animals to not attack human is best for human survival :)

Animal behaviorists have found that animals gain from developing bonds with trustworthy humans, but doing so calls for a lot of motivation and understanding about the animal's behavior.

What is animal behavior?

The scientific study of non-human animal behavior is called ethology, and it often focuses on behavior in natural settings and sees behavior as an evolutionary adaptive quality.

Animal behavior is an animal's response to stimuli, and there are both acquired and intrinsic types of animal behavior.

Dogs who have been trained to obey commands are an example of animal behavior. In contrast, inherent behavior includes mating cues like bird crowing and peacock dancing before a storm.

Animals benefit from forming relationships with dependable humans, according to animal behaviorists, although doing so requires a lot of drive and knowledge of the animal's behavior.

Anyone lacking sufficient motivation or missing the necessary knowledge could suffer considerable harm if they attempted to interact with the animal.

Thus, it is important to design field studies that will not make wild animals associate humans with food.

Answers

If there is a change in a squid's messenger RNA, this change does not appear in its genetic material. This change neither will be inherited by its offspring.

What is messenger RNA?

During gene transcription, a fragment of DNA called gene is used as template to generate a messenger RNA (mRNA).

Subsequently, this mRNA is used as a template to create a protein by a process known as translation.

The mRNA is a molecule that carries the genetic material from DNA to protein but this process does not modify the genetic material.

How are the bodies of the three animals similar to one another? How are they different?

Answers

Answer:

How are animals similar? All animals are made of many cells. Most animals can move on their own. Like all living things, animals grow, change, reproduce, and respond to their environment.

Animals are made up of several cells. Most animals have independent movement. Animals develop, transform, reproduce, and react to their surroundings like all other living creatures do.

What are considered as animals?

Any eukaryotic multicellular organism of the biological kingdom Animalia is referred to as an animal.

The majority of creatures in this kingdom lack a cell wall, are heterotrophic, motile, have specialised sensory organs, and originate from blastulae during embryonic development.

According to some, the fundamental distinctions between humans and other animal species are our capacity for complex reasoning, our use of complex language.

Also, the capacity for problem-solving, and the capacity for introspection (this means describing your own thoughts and feelings).

Multiple cells make up an animal. The majority of animals can move on their own. Like all other living things, animals grow, change, reproduce, and respond to their surroundings.

Thus, this way, many animals contrasts each other.

Pea plants can have yellow seeds or green seeds. which conclusion about the meaning of y is correct if the allele combination yy is for yellow seeds? yellow and dominant green and recessive yellow and recessive green and dominant

Answers

Pea plants can have yellow seeds as the meaning of y is correct if the allele combination yy is for yellow seeds are yellow and dominant.

This question involves a seed color gene, which has two alleles Y and y. Y, which represents the dominant allele codes for the YELLOW trait while y which represents the recessive allele codes for the GREEN trait. Therefore, a plant with Yy will have YELLOW SEEDS because the dominant Y allele is present.

What are two alleles?

Gregor Mendel has stated that a gene comes with two alleles. According to his law of dominance, one of the alleles called the DOMINANT allele is capable of masking the phenotypic expression of another allele called the RECESSIVE allele.

Thus it is clear that yellow and dominant are the meaning of y is correct if the allele combination yy is for yellow seeds.

hi there, proteins are related to DNA  because DNA carries the instruction for synthesizing  proteins, which can code for a certain amino acids based on the sequence.

Explanation:

A change in  base sequence can be either good or bad. But... Usually... a mutation could be a main factor that changes the sequence of the protein, which causes it to code for a different amino acid than the original. Base pairs could either substituted,  deleted, or inserted, which usually are what a mutation could be caused by or consisted of. This is also known as a gene mutation, which are changes in genes .

Explanation:

The temperature and name of the surface ocean current which affects the climate of the location E is the Cool California Current. Thus, the correct option is 4.

What is the Cool California Current?

The California Current is called as an eastern boundary current. The strong current systems which flow along the east side or the boundary of all of the Earth's major ocean basins. These tend to move the water towards the equator, and they are prone to strong upwellings.

The temperature and salinity of the waters of the California current vary with the seasonal variations in the upwelling, insolation, and flow of the water. The maximum range in the temperature and salinity from its northern to its southern end are 48° to 79° F or 9° to 26° C and 32.5 to 34.5 parts per thousand, respectively.

Therefore, the correct option is 4.
