Which of the following statements best compares genetic diversity in eukaryotes and prokaryotes?A. Both eukaryotes and prokaryotes can transfer DNA using conjugation and fertilization.
B. Eukaryotic species experience a greater rate of mutations within their populations.
C. Mutations increase the genetic diversity in both prokaryotes and eukaryotes.
D. Sexually reproducing eukaryotes evolve faster than species that reproduce asexually.

Answers

Answer:

C. Mutations increase the genetic diversity in both prokaryotes and eukaryotes.

Explanation:

It is a well-established fact that mutations increase the genetic diversity in living organisms (especially if they are positive mutations). The positive and faster mutations will help the organism to develop better traits for survival in the changing environments.

The other options are incorrect because of the following reasons:

A. Eukaryotes don't do gene transfer via conjugation.

B. Eukaryotic species don't experience a greater rate of mutations as compared to the prokaryotes. Prokaryotes have a faster mutation rate. This is the reason that microbes can adapt to changing environments faster than humans or other multicellular organisms.

D. As mentioned above, sexually reproducing eukaryotic species evolves slower than the asexually reproducing species. For example, evolution in bacteria (e.g. drug resistance) is faster than any organism belonging to eukaryotic lineage.

Answer:

C .  Mutations increase the genetic diversity in both prokaryotes and eukaryotes.

What protects the lining of the stomach from acidic gastric juices?A.
salt
B.
pepsin
C.
mucus
D.
amylase

Answers

Mucus protects the lining of the stomach from acidic gastric juices.

What is gastric juice?

Hydrochloric acid (HCl), lipase, and pepsin come together specifically in gastric juice. Its primary purpose is to render ingested bacteria inactive, preventing infectious pathogens from entering the intestine.

Squamous epithelium, like the skin, is found in the mucosa of the mouth and the esophagus and is thought to serve as a barrier against infection.

Gastric juice makes food particles soluble, starts digestion (especially of proteins), and transforms the contents of the stomach into a semiliquid material termed chyme, laying the groundwork for subsequent small intestine digestion.

Therefore, Mucus protects the lining of the stomach from acidic gastric juices.

Answers

A Venus flytrap produces new leaves from the step tip. The life characteristic that this illustrates is A. Growth. Venus Flytraps are composed only of leaves, and rather than sharing a root system, each leaf grows its own root or roots, and each root is a single structure, not dividing or

scientists observed a key characteristic that required reclassification. What
was that characteristic? *

Answers

Reclassification of fungi

Explanation:

Fungi were classified under kingdom plantae by the earlier taxonomists due to their similarities. Both of them were grown on the ground and fixed to the ground, they do not move, fungi like plants also produced fruiting bodies.

However, there were many physiological, morphological, genetic, and biochemical features which were unique and different from other kingdoms.

Although, the fungi contain similar features like vacuoles, secondary metabolites, myecelial root-like structures; fungi like plants do not have a complete vascular system.

Hence, the previous classification under plants was reconsidered and fungi were reclassified as a separate kingdom next to the protists and before the plantae kingdoms.

If i show a dominant trait do one of my parents have to show the same trait? explain?​

Answers

well, not exactly like some parents have blue eyes and they have a dominant brown eyed child. This can happen because of the gynotype. The history of the child’s parents probably have some brown eyes which caused the child to have brown eyes. But usually the parent does express a dominant trait like the child.
