A variation that results in increased fitness is more likely to be passed on  because the individual will reproduce. thus option B is correct.

Genetic diversity is endlessly possible as a result of sexual reproduction. In other words, sexual reproduction produces genetically distinct offspring. They are different from one another as well as from their parents.

Variation will be passed on through reproduction. reproduction results in genetic variation which increase the chance of survival of new organisms.

Two control systems of the body

Endocrine and Nervous

Endocrine and nervous system similarities

-Work together to maintain homeostasis

-Release ligands (chemical messengers) that bind to cellular receptors on particular target cells

Endocrine and nervous system differences

Endocrine system: -Transmits hormones through blood

-Targets any cell in the body with the correct receptor

-Very widespread

-Exhibits longer reaction times and has longer-lasting effects

Endocrine System

-Composed of ducts and glands that synthesize and secrete hormones

-Hormones are released into the blood and transported throughout the body

Endocrine system regulation growth and development

-Changes measured from birth to puberty

-Hormones help regulate embryonic cell division and differentiation

-Hormones regulate metabolism

How does the endocrine system maintain homeostasis or blood composition and volume

-Hypothalamus

-Hormones regulate blood solute concentrations (ex glucose ions)

-Hormones regulate blood volume, cellular concentration, and platelet numbers

The endocrine system controlling digestive processes

-Trigger digestion when food is in the stomach

-Hormones influence secretory processes and movement of materials in the digestive tract

Endocrine System controlling Reproductive Activities

-Make sure sperm and egg make it to each other

-Hormones affect the development and function of the reproductive system and the expression of sexual behavior

Endocrine Glands

Contain epithelial tissue that makes and releases hormones within a connective tissue framework

Endocrine Organs

-Glands with solely endocrine functions

-Ex: Pituitary, pineal, thyroid, parathyroid, and adrenal

Endocrine Cells

-Found in clusters in organs with another function

-Examples in Hypothalamus, Thymus, Heart, Stomach, Liver, Pancreas, Small Intestine, Adipose Connective Tissue

-Pancreases is not an endocrine gland, but it does release hormones

Answer:

Not always. We are constantly learning more and more about the universe, and what we find is forever changing. these scientific laws could change at a moment's notice. While they are reliable, you shouldn't trust anything 100% all the time.

Answer:

The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function,

reproduction, sleep, and mood, among other things.

Explanation:

The skin shields the body from external conditions and aids in the regulation of the body's internal functions as part of the integumentary system.

The integumentary system is a collection of organs that make up the body's outermost covering. It is made up of the skin and its appendages, and it serves to protect and preserve the animal's body by functioning as a physical barrier between the exterior and interior environments.

The excretory system's skin, on the other hand, acts as a regulator for the amount of fluids and salt in our bodies.

Replicability is the repetition of the experiment by other researchers who get the same results as the original experiment. B) Other students repeat the same procedure on other potatoes.

Following the scientific method, an experiment needs to be replicable.

Replication refers to the need of repeating a research study, under different situations, different subjects, and with different researchers to determine the safety of the original findings and their possibility of generalizing them to other situations and participants.

Replicability is the possibility of carrying out the same experiment by other researchers. When repeating the experiment, results should be the same, or with a minimal variation. Results heterogeneity should be minimal.

Option B is correct. Have other students repeat the same procedure on other potatoes.

The exact same experiment will be repeated by different students -researchers- and their results should be the same as the ones of the first student -potatoes are 40% water-.
