Explanation:

Comparing prokaryotes and eukaryotes

All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.

The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.

Answer:Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene. Some traits are caused by mutated genes that are inherited or that are the result of a new gene mutation.

Explanation:

Answer: D) Polygenic

Explanation: Polygenic inheritance describes the inheritance of traits that are determined by more than one gene. These genes, called polygenes, produce specific traits when they are expressed together. Polygenic traits have many possible phenotypes (physical characteristics) that are determined by interactions among several alleles. Examples of polygenic inheritance in humans include traits such as skin color, eye color, hair color, body shape, height, and weight.

Answer:

Directional selection

Explanation:

Natural selection is the process by which environment selects from a population of organisms which individuals are better suited and adapted to that environment. There are three types of natural selection namely: directional selection, disruptive selection and stabilizing selection.

Directional selection is the type of natural selection in which only one extreme (phenotype) of a population is favored over the other extreme and intermediate individuals. This is the case in the example given in the question where among a group of white, grey, and black rabbits that lives in Alaska, environment selects the white rabbits (one extreme) from wolf predation, hence, causing the white rabbit population to increase and be favored.

Answer:

A. freckles

Explanation:

inherited traits are things you are born with that resemble your parents like freckles, color hair and skin even eyes and other such things

The inheritance of traits depends on the genes, not on the somatic cells. In the given choices, freckles are inherited from parents to offspring.

Freckles are caused by either sun or by genes. The presence of this can be due to the genes carrying it.

Genetics and sun exposure is the main cause of freckles. There are a number of genes involved, and they can interact with one another in lots of different ways.

Somatic variations are not likely to get inherited.

Thus, the correct option is A.

Answer:

The model doesn’t clearly show that gas exchange happens in the alveoli through the capillaries. The model can also be easily misinterpreted. Because the model doesn’t show where this gas exchange is taking place, it looks like the blood picks up oxygen, delivers it to the body, and then comes back and expels the carbon dioxide it collects. Clarifying that this gas exchange is taking place in the capillaries would eliminate this confusion.

Answer:

Mismatch DNA repair mechanism recognizes the abnormal base pairing (G-G base pair) and may correct it by converting the D allele to d

Explanation:

The DNA mismatch repair can be defined as a specialized mechanism that recognizes and repairs errors in the nuclotide sequence (such as, for example, bases erroneously incorporated) during DNA replication and recombination. The DNA mismatch repair is a system that also acts to repair the DNA after damage. It has been shown that the DNA mismatch repair mechanism leads to the generation of a DNA molecule with one chain that has the nucleotide sequence arising from DNA repair and one parental chain. In this case, it is expected that the DNA mismatch repair mechanism will identify the abnormal G-G base pairing and then this system may change the D allele to a d allele by introducing a C base instead of a G base in the DNA strand.

Answer:

the objects have very large masses or an object in circular orbit. This has motion but its always being to pulled to earth by gravity.

Greater gravitational forces will be used to attract heavier things, since the gravitational force is directly proportional to the mass of both interacting objects. Two objects are attracted to one another by gravity as their respective masses increase. Thus, option B is correct.

The gravitational pull between two objects changes inversely with their squared distance and directly with their large masses.

As a result, the gravitational force between the two items would decrease to one-fourth of its initial strength when the large masses of both objects are halved without affecting their distance.

Therefore, The objects are either in a circular orbit or have extremely  large masses. Although something is moving, gravity is always bringing it dangerously close to the ground.

I wonder how you would explain that both men and women are living much longer. In 1900 the average ago of mortality was 42 years old in the United States. We have nearly doubled that. In the province (Canada) where I live the mortality rate is nearly 81 years old. That is a huge improvement.

We have done in spite of contaminated air, oceans that resemble sewage sump (there is a plastic dump the size of Texas somewhere in the Pacific and the Atlantic is little better), a population increase that is unbelievable in terms of %. I wish my stocks would show that kind of % increase, and the current biological crisis -- I'm not allowed to name it. (There have been several of these pandemics since 1900.)

Answer:

apes are very related to humans. there's only one difference in their dna sequence.

sharks are least related to humans because we diverged from them a long time ago through divergent evolution.

humans and apes share homologous structures such as arms, legs, tailbone, and fingers that are similar in function.

the differences between humans and apes are that they have a tail, whereas we do not, and their vocal cord hasn't evolved as much as ours.

apes are more vulnerable since they can't innovate weapons and defend themselves with tools like we once did.

humans are more likely to survive because we are strong in number, and our teamwork can triumph any challenges.
