Answer:
Natural selection, mutation, and genetic drift are random events.
Explanation:
A mechanism of evolution in which the frequencies of alleles of a population change with generations because of sampling error is known as genetic drift. It takes place in all the populations of non-infinite size, however, its influences are strongest in small populations.
Hope this helps :)
I think it’s A B and C because other sloths are alive and so are trees.
Answer:
Aerobic respiration process produce either 36 ATP or 38 ATP depending on the amount of NADH moles while Anaerobic produces 2 ATP. Aerobic respiration produces 32-34 ATP more
Explanation:
Aerobic respiration has 3 steps which includes; Glycolysis which produces 2ATP; Krebs cycle which produces 2 ATP and Electron Transport Chain which produces 32 - 34 ATP depending on the molecule of NADH introduced into the reaction from the kreb cycle
An embryonic stem cell is the first cell in the embryo, this is what creates a human and helps more cells to form.
Answer:
The Thymus is a unique gland which protects the body against autoimmunity when the immune system act against itself.Hence the Thymus plays a significant role the dual systems i.e.,the lymphatic system (body’s defensive mechanism) and the endocrine system
Explanation:
The Thymus is special gland located anteriorly to the chest directly behind the sternum and in between the lungs. Active until puberty and gradually shrinks to become fat after puberty.
Function: Prior to birth and during childhood thymus engage in producing and maturation of T-lymphocytes or T-cells a particular type of white blood cells which defence the body against infectious disease germs.Though the organ does not function throughout the life span but it plays a significant role protecting the body against autoimmunity refers to an immune system works against itself .Therefore the thymus plays a key role in lymphatic system and an endocrine system.
Secretion:Thymus secretes Thymosin a hormone it instigates the development of T-Cells ( disease resisting cells) Thymosin stimulates the development of T-Cells until a human attains its puberty.
At the age of 75 thymus becomes a fatty tissue.
