Explanation:

The problem with grouping organisms together taxonomically based on their physical traits is that organisms that not genetically or evolutionally similar would be grouped together. Grouping would be based entirely on superficial similarities instead of combining different features such as genetics, nutrition, the complexity of bodies, etc.

Based on physical traits, for example, all flying organisms will be grouped together. Birds, flying insects, bats, etc. would be grouped together, whereas, they are quite different from one another when it comes to the complexity of bodies and other features. Even though some insects have wings and can fly like birds, insects have exoskeletons and birds do not, the body of birds is more complex than that of insects, and evolutionally, birds are more advanced than insects.

Hence, grouping organisms based on their physical traits only would be too superficial and not reflect the true relationships between organisms.

I think the answer is B. Immigration must outpace emigration. Hope this helps!

Hardy-Weinberg equilibrium is the principle of the genetic variation being constant. Each allele must be equally beneficial for a population to be in equilibrium. Thus, option C is correct.

Hardy-Weinberg equilibrium states the invariant nature of genetic variation when there are no disturbing factors in a population. For an equilibrium condition, the population should have a large size. Each allele must be equally beneficial so that there is no genetic drift.

There should be no immigration or emigration of the organism in a particular population as it affects the generation and individuals. Also, there must be no spontaneous mutations for the variation to occur.

Therefore, each allele must be equally beneficial for equilibrium.

Answer:

The gases will be together since they do not possess kinetic energy

Explanation:

let us use the kinetic theory of matter to explain the condition of the gas in the morning.

During the day, the atmosphere can be very hot so the gases tend to be in constant random motion, hence they will move away from themselves because they possess kinetic energy.

In the morning the temperature of the atmosphere is relatively low and the vehicle is not in motion, hence the gases will move together because they no longer possess kinetic energy anymore

Why must an mRNA copy be made for Protein Synthesis because C. Ribosomes are too big to enter the nucleus

mRNA is the molecule that includes the message contained within DNA to the ribosome. Ribosomes are where proteins are produced. mRNA is vital because ribosomes cannot attain the DNA inside our cell nucleus, which is the region within the mobile wherein DNA is housed.

Why is it important to make an mRNA reproduction of a DNA gene earlier than protein synthesis?

So as for cellular to fabricate these proteins, particular genes inside its DNA should first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into completely useful proteins.

Answer:

40kg

Explanation:

F=M*A

M=F\A

M=400\10

M=40kg

The mass of an object whose weight is 400 N and acceleration due to gravity is 10 m/s2​ is 40 kg.

The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g.

It is a vector quantity whose direction, strength, or magnitude match a plumb bob.

According to Newton's second law, an object's acceleration is inversely proportional to its mass and directly connected to the net force. An object's acceleration is determined by two factors: force and mass.

We know that,

F = m x g

m = f/g

Where,

F = force

m = mass

g = acceleration due to gravity

Given that,

F = 400N.

g = [tex]10m/s^2[/tex]

So,

m = 400/10

m = 40 kg.

Thus, the mass is 40 kg.

Explanation:

Answer: b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.

Explanation:

In the negative feedback loop, the feedback reduces the excessive response of the stimulus for example regulation of body temperature, and control of blood glucose level. In the positive feedback loop, the response of a stimulus is intensified. Example, positive feedback is the childbirth and blood clotting. According to the negative feedback loop the output of the system keeps the internal body environment constant with respect to the changes in the external environment hence, maintains the homeostasis.

Answer:

b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.

Explanation:

The yellow allele is incompletely dominant.

Genetic variation distribution in families is characterized by inheritance patterns. Predicting disease risk in a patient's family requires an understanding of these patterns.

Conditions brought on by pathogenic variations in a single gene are referred to as monogenic or Mendelian conditions.

Depending on the pattern of inheritance, a gene may be influenced by either one or both alleles.

Answer:

Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio (base pair rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine

Chargaff's Rule explains that in the natural DNA, the total number of guanine equals to the number of cytosine and the total number of adenine equals to the number of thymine. This tells about the base pair composition of DNA molecule.

Chargaff's rule states that in the DNA molecule of any species or organism, the total amount of guanine residues should be equal to the amount of cytosine residues and the amount of adenine residues should be equal to the amount of thymine residues. A stoichiometric ratio of 1:1 of purine and pyrimidine bases i.e., A + G = T + C should be fulfilled.

Chargaff's rule describes the ratio of the various nitrogenous bases present in the DNA molecule. It aids in the determination of the structure and composition of DNA in living organisms. It is constant for a species.
