Different evolution theory of living organism​

Biology
1 answer:
Neporo4naja [7]3 years ago
4 0

Answer:

<em>(I) Lamarckism or Theory of Inheritance of Acquired characters.</em>

This theory is based on the comparison between the contemporary species of Jean Baptiste de Lamarck's time to fossil records.

<em>(II) Darwinism or Theory of Natural Selection.</em>

Charles Darwin made an extensive study of nature for over 20 years, especially in 1831-1836 when he went on a voyage on the famous ship “H.M.S. Beagle” and explored South America, the Galapagos Islands and other islands.

<em>(III) Mutation theory of De Vries.</em>

The mutation theory of evolution was proposed by a Dutch botanist, Hugo de Vries (1848-1935 A.D.) in 1901 A.D. in his book entitled “Species and Varieties, Their Origin by Mutation”. He worked on evening primrose (Oenothera lamarckiana).

<em>(IV) Neo-Darwinism or Modern concept or Synthetic theory of evolution.</em>

The detailed studies of Lamarckism, Darwinism and Mutation theory of evolution showed that no single theory is fully satisfactory. Neo-Darwinism is a modified version of theory of Natural Selection and is a sort of reconciliation between Darwin’s and de Vries theories.

The two systems that work together to cause this reaction are the endocrine system that secretes the hormone and the
Simora [160]

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

Page No Date Sex in bacteria is deteaimined by ?<br>​
VladimirAG [237]

Answer:

Pili

Explanation:

The sex of bacteria is determined by a structure called Pilli. Pilli is not present in all species of bacteria, but within species that have this structure, such as Escherichia coli, pilli is considered an appendage present in male bacteria.

Pilli presents itself as a long hair and can also be called F factor or fertility factor and has a reproductive function, as it allows the conjunction between two bacteria (one with pili and the other without), where the male bacteria transmit genetic resources to within the body of the female bacteria , which will combine these resources with its own resources and will give rise to another bacteria.

Which of the following is a direct result of antidiuretic hormone?
ElenaW [278]

Answer: Option A.

Decreased urine volume.

Explanation:

The direct result of antidiuretic hormone is decreased urine volume because it is the hormone secreted by the hypothalamus of the the brain and stored pituitary gland which control blood pressure and make the kidneys to release less water, as little water is released by the kidneys, there will be little amount of urine produced.

This hormone reduce the urine volume or amount of urine produced.
