The genetic information contained in DNA consists of a linear sequence of coding units, known as codons. Each codon consists of three adjacent DNA nucleotides that correspond to a single amino acid in a protein. The E. coli DNA molecule contains 4.7 x 10^6 base pairs. Determine the number of codons that can be present in this DNA molecule.
Answer:
The correct answer is - 1.57 × 10⁶ codons.
Explanation:
Given:
No. of base pairs in E.coli DNA = 4.70 × 10⁶
we know :
1 codon = 3 DNA nucleotides
Solution:
No. of of base pairs in DNA = No. of nucleotides in a single strand
= 4.70 × 10⁶
It must have 1/3 this number of triplet codons
= 4.70 × 10⁶ / 3
= 1.57 × 10⁶ codons.
Thus, the correct answer is - 1.57 × 10⁶ codons.

inhumane farming methods are detrimental to both crops and animals .Critically discuss how animals get affected
Answer:
In an ecosystem when plants don't exist or dies out all animals while die because herbivorous depends on plants when plants die they also die making the carnivores also die due to lack of food
There are lots of harsh and cruel farming methods that are very harmful to crops and animals, If not well controlled these farming method could pose a very serious threat to crops and animals thereby leading to shortage in food supply.
These methods include;
- Uncontrolled dumping of waste; waste products from farm animals should be dumped properly to avoid contamination and spread of diseases.
- small farm space; a lot of farmers today do not have enough land/fields where animals can roam free, these animals are secluded to a tiny space causing cross contamination between these animals
- giving growth hormones to farm animals is also a very bad practice, these animals should be allowed to grow at their own pace.

Answer:
I don't understand the question that well but from what I understand I have to say how they relate or effect each other.
Mass. Mass can be effected by your weight and height. Your weight can help increase mass but size matters to. Think of gold. Gold is very dense so it's mass is greater. when you pick up an equal size of gold and another object gold will feel heavier because of its size and weight.
Weight. think of gold as well. Because of its mass it feels heavier. Weight can also mean it is larger. Think of a pebble and a boulder. They are both stone so we can compare them. A boulder is larger and it is heavier.

One adaption to life in flowing water is what?
Answer:
Explanation:
There are many options, here are a few choices:
Fast moving water tends to be colder than slow water; some of it originates as snow melt on the sides of mountains, for example. For this, animals in fast water tend to be more cold resistant. This is why you do not see fish like freshwater trout in equatorial regions. These animals struggle and die in slow, warm water.
Fast moving water means that if the animal or plant wants to stay put, it must resist the flow. Fish tend to be far more muscular and lean in these places, while insects like stoneflies, mayflies, and other larvae have ways to secure themselves to rocks and plants while growing. Plants develop strong root systems, and algae hold fast in rocky crevices in the river. Some animals also have suction in order to stay in place where there is fast flowing water.
Some animals have to adapt their reproductive systems as well. Because finding a mate is difficult in the sweeping waters, breeding tends to happen all at one time. As an example, salmon have runs, where thousands of fish all swim upriver at once to breed, can dramatically alter the surrounding ecology of the river. Insects like mayflies have hatches, where hundreds of thousands of flies swarm into the air at once to breed and lay eggs.

Fibers used in textiles can be either natural or synthetic. Cotton and Linen are different variants of cellulose fibers. Wool is natural polyamide (protein) fiber. Nylon and polyester are variants used in synthetic fibers. There are 35 kinds of amino acids used in making proteins, and most proteins have 50-1000 amino acids in the chain. What does this say about the number of different kinds of proteins available in nature
Answer:
Proteins are very varied, and the number of junctions and the arrangement in which these junctions are found depends on this.
In addition to taking into account the amount of amino acids.
Explanation:
Proteins in nature are found in great variety, this is due not only to the amount of amino acids present, but the multiple combination options between these amino acids, we must not ignore the unions, that is why some proteins are more complex what others.
Proteins have different unions and this makes it have different coformations, there are primary, secondary, tertiary and quaternary unions, if the protein has all these unions it is considered complex, whereas if it has the simplest it is considered a simple protein.

Fungi tend to reproduce sexually when nutrients are limited or other conditions are unfavorable,but they reproduce asexually in more ideal conditions. Why is this strategy successful?The fungal colonies reproduce by the process of asexual reproduction during the availability ofnutrients. When favorable conditions are present the fungi are succeed, therefore fungi do notchange its growth features. When conditions are unfavorable the fungi undergo sexualreproduction process. Sexual reproduction produces offspring which are distinct from the parent.This strategy is successful because this reproduction increases genetic variation, which entailsthe odds of some progeny, which are suited to new and challenging conditions. When nutrientsare available in plenty the mother cell do not depend on the other cells, rather multiply by mitosisgiving rise to daughter cells but during unfordable conditions
Answer:
Sexual reproduction produces offspring which are distinct from the parent.This strategy is successful because this reproduction increases genetic variation, which entailsthe odds of some progeny, which are suited to new and challenging conditions.
Explanation:
Sexual reproduction produces genetic variability, as two nucleic unites to produce a new offspring this allows the fungus to adapt to new environments. Sexual reproduction in the fungi consists of three sequential stages plasmogamy, karyogamy, and meiosis.
It involves diploid chromosomes pulled into two daughter cells, each containing an haploid set of chromosome.
Plasmogamy is the fusion of two protoplasts which brings together two compatible haploid nuclei this nuclear types are present in the same cell, but are not yet fused. Karyogamy then leads to the fusion of the haploid nuclei and the formation of a diploid nucleus. The new cell formed by karyogamy is the zygote.
In the carbon cycle, how is carbon stored in organisms and then exchanged with the environment?
Answer:
Photosynthesis, Decomposition, Respiration and Combustion.
Explanation:
The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. In the natural carbon cycle, there are two main processes which occur: photosynthesis and metabolism. During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product.
7. In what other places, besides central Africa, can people with a high eumelanin content be found
living today?
Answer:
Although people living in low latitudes have high levels of eumelanin, this pigment can be found in people around the world (because it is predominant in people with brunette hair)
Explanation:
In animals and humans, melanin pigments play key roles in eye, hair, and skin coloration. Basically, there are three main types of melanin pigments: eumelanin (brown-black and insoluble), pheomelanin (yellow-red and soluble in alkali solution) and neuromelanin (found in some parts of the brain). Eumelanin is predominant in black people and brunette hair people, this being consequently found around the world. There are two distinct classes of eumelanin: black eumelanin and brown eumelanin, which differ in their patterns of polymeric bonds, and they have an incidence on the type of coloration (e.g., black eumelanin is found in people with grey hair).

Answer:
Controlled Investigation
Field Investigation
Explanation: In a controlled experiment, the scientist has total control over the environmental conditions. The temperature, humidity, amount of light, amount of noise, materials, etc. can all be controlled and monitored by the scientist throughout the investigation.
A field investigation involves observing and measuring plants and animals (including people) in their natural habitat or environment without changing, harming, or altering the setting or any part of the test subjects. Like in a controlled experiment, the scientist chooses to observe and measure how one change (IV) has a measurable effect (DV) on something else.

An individual with Huntington disease has two normal parents. What are plausible explanations for this pattern of inheritance? Check all that apply. Check All That Apply A spontaneous mutation occurred in the mother's germline to produce a mutant HD allele. A spontaneous mutation occurred in the mother's germline to produce a mutant HD allele. A spontaneous mutation occurred in the father's germline to produce a mutant HD allele. A spontaneous mutation occurred in the father's germline to produce a mutant HD allele. A spontaneous mutation occurred in the individual's germline to produce a mutant HD allele. A spontaneous mutation occurred in the individual's germline to produce a mutant HD allele. Huntington disease shows incomplete penetrance.
Answer and Explanation:
The Huntington disease is caused by a mutation in the gene that codifies for the Huntingtin protein (Htt). The mutation produces an altered form of the protein leading to the neuron´s death in certain areas of the brain.
The Huntington disease characterizes for being,
Hereditary, passing from generation to generation. To express the disease, a person must have been born with an altered gene. Autosomal, affecting men and women equally, because the mutated gene is located on an autosomal chromosome.Dominant, which means that by getting only one copy of the altered gene coming from any of the parents, the receiving person will express the disease. The mutation in the gene dominates over the normal gene copy. Expressed by heterozygosis. Most people affected by the disease are heterozygous, with a normal copy and a mutated copy.There are just a few cases all around the world (3% approximately) in which the disease is expressed with no family history. The progenitors are not affected by the mutation. These cases are very rare and are called "de-novo" mutations. A new mutation is spontaneously produced and it is not inherited from any of the parentals. It consists of an increase in the number of CAG repetitions. In a normal person, the number of CAG repetitions is less than 35. When there are 40 or more repetitions it occurs the disease. But when there are between 35 and 39 repetitions, the penetrance of the disease is incomplete. This is a "gray zone". Those alleles that fall in the gray zone are unstable and might produce the HD. Individuals with these unstable alleles have a tendency to increase the number of repetitions from generation to generation until the number reaches 40 repetitions and the person expresses the disease. This usually occurs in the paternal germinal line, as it is particularly unstable in sperm and probably meiosis greatly affects their instability, causing an increase in the number of CAG repeats.
