Evolution is change in a population over time and includes the gene pools of that population. How does biogeographic isolation allow for the change of gene pools over time

Answers

Answer 1

Answer:

OPTIONS:

A) biogeographic isolation affects the random changes that take place within gene pools

B) biogeographic isolation affects the changes in gene pools that result from which organisms are breeding

C) biogeographic isolation determines who will win competition for mates

D) biogeographic isolation determines the time that populations will breed

Answer:

A) biogeographic isolation affects the random changes that take place within gene pools

Explanation:

Organisms can become splitted and isolated from each other by biogeographical factors, thereby preventing the isolated population of species from interbreeding with each other. When this occurs, the isolated population, over time, evolve separately and later become distinct from each other leading to a change in the original gene pool.

Biogeographical factors uch as habitat isolation can cause a change in the original gene of a species population which have now become isolated geographically, and thus, evolve separately.

Which of the following is (are) not the function (s) of the skeletal system: support, storage of minerals, strength, or production of blood cells (hematopoiesis)?

Answers

Answer:

strength

Explanation:

Skeletal system of the human body has 206 bones. Human skeleton is divided into appendicular skeleton and axial skeleton.

The skeletal system provide support to the other parts of body, chemicals like calcium are stored in the skeletal system and red bone marrow is the site of hematopoiesis. The skeletal system doesnot provide strength because muscles are mainly involved in providing strength to the body.

Thus, the correct answer is option (3).

Which cell is a plant cell?

Explanation:

Steve has had a stroke and comes to you for follow-up today. On examination you find that he has increased muscle tone, some involuntary movements, an abnormal gait, and a slowness of response in movements. He most likely has involvement of which of the following? A) The corticospinal tract
B) The cerebellum
C) The cerebrum
D) The basal ganglia

Answers

Answer:

D) The basal ganglia

Explanation:

Basal ganglia is located at the base of forebrain and the top of midbrain. It is involved in many functions because it is connected to many parts of the brain like thalamus and cerebral cortex. One of the functions of basal ganglia is to control the voluntary movements of the skeletal muscles.

Damage to basal ganglia can disturb the muscles causing involuntary movements, abnormal gait and increased muscle tone. For example, muscle tone is the tension in skeletal muscles caused due to minor involuntary contractions. Substantia nigra part of basal ganglia is responsible for controlling it. If it is damaged, muscle tone can increase which will cause unnecessary tension in skeletal muscles leading to uncontrolled movements.

You have been reading for a while and want to rest your eyes and listen to the next section of your chapter. You have finish reading the assignment for the next quiz but want some extra review with flashbacks. You begin reading your E texts with blank letters against a white background but want to try changing the color mode to sepia instead. You have highlighted importing content, and added notes as you read.Now you want to compile and export these notes as a pdf study reference. You’ve highlighted important terms and ideas in your e text . Now you want to hide your highlights as you review for an exam.

Answers

To rest my eyes and listen to the next section of my chapter, I'll consider using text-to-speech functionality. After finishing the assignment for the next quiz, I'll review it with flashbacks to reinforce my understanding. Changing the color mode to sepia can be a soothing option for reading.

For compiling and exporting notes as a PDF study reference, I'd typically use note-taking or document management software. I'd also look for options to export highlights separately.

To hide the highlights during exam review, I'd check if there's a way to turn off the highlight display in my e-text software temporarily. If not, I may consider making a copy of the text without highlights for focused study.

In humans, one function of the skin is to prevent water loss. Skin releases water or holds in water when necessary.Which two structures in plants have a similar function to skin?

> roots and chloroplasts

> phloem and roots

> cuticle and stomata

> stomata and phloem

Answers

Cuticle and stomata in plants have a similar function to skin.

What are the functions of cuticles?

The cuticle is well known for its functions as a diffusion barrier limiting water and solute transport across the apoplast and for its protection of the plant against chemical and mechanical damage, as well as pest and pathogen attack.

In some higher plants, the cuticle is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss. It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue.

The cuticle itself comprises three layers: the cuticular layer; cuticle proper; and epicuticular waxes. The cuticular layer is the innermost layer, which overlays the primary wall and consists of cellulose and other polysaccharides along with cutin and wax.
