Offspring with a 3:1 ratio suggest that both parent that both parent that give rise to this offspring were both heterozygous. Heterozygous individual is someone who has two different allele at a locus whereby by one gene is dominant over the other gene. example of heterozygous parent is a parent Aa pair of alleles. In this pair gene A is dominant over gene a
Flagelle - 4
Pseudopod - 2
Autotroph - 8
Prokaryote - 1
Heterotroph - 3
Hope this helps ;)
I am not 100% sure but I thinking it responds when pathogens enter the body because the immune system is meant to protect your body from illness.
Answer: These contractions need energy from respiration , and some of this is released as heat. Blood vessels, which lead to the skin capillaries, become narrower - they constrict – which allows less blood to flow through the skin and conserve the core body temperature. This is called vasoconstriction.

Answer:
C. the sympathetic division of the autonomic system.
Explanation:
The sympathetic nervous system is one of the divisions of the autonomic nervous system that controls involuntary body functions in the body. The sympathetic nervous system is said to stimulate the fight-or-flight response of the body when the body senses threat, or is exposed to a stressor. These fight-or-flight responses are generated in the body in form of physiological changes in order to put the body at top alert to focus on dealing with the stressor.
Physiological changes that are stimulated by the sympathetic nervous system as fight-or-flight responses include dilated pupils, inhibited digestive activity, increased respiratory rate, and release of glucose from the liver, which are all stated in the question. It is the sympathetic division of the autonomic nervous system that controls all these activities.
