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.
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).

Answer:
b
Explanation:
B) The cerebellum
C) The cerebrum
D) The basal ganglia
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.

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