True. In mammals, an increase in the temperature of the preoptic area of the hypothalamus activates physiological mechanisms for heat dissipation including vasodilation.
<h3>What is
vasodilation?</h3>
Vasodilation, as it is known in medicine, occurs when blood vessels in your body open up, enabling more blood to flow through them and resulting in a reduction in blood pressure. Without your knowledge, your body goes through a routine procedure like this. It can also be brought on by the foods and beverages you consume as well as the drugs you take. Vasodilation may also be a sign of a particular illness.
The two of the many functions that your blood serves in the body:
- Carrying oxygen and nutrients
- Aiding in temperature regulation in your body.
Your body's blood arteries are more complex than simple tubes that remain constant in size. Your blood arteries include muscle as well, and that muscle regulates how wide or narrow they are at any particular time. Vasodilation occurs when blood vessels enlarge. Vasoconstriction is the opposite process, which occurs when blood vessels narrow and contract.

<span>Microglia is glial cells found in the central nervous system with the protective role. Because they are the resident macrophage cells, they act as the first and main form of active immune defense.

According to the observation, I would conclude that the fungus has asexual form of reproduction. This is because asexual spores germinate and produce new hyphae anytime and anywhere as long as the conditions are favorable. Sexual pores on the other hand need a time of dormancy after the are formed before they produce more hyphae.
Answer:
Independent assortment
Explanation:
The law of independent assortment says that genes for different traits or characteristics assort independently from each other during gamete formation. So each contrasting character's pair assort independently and do not show any association with the pair of other characters.
So after gamete formation collectively the gametes have all the possible combinations of alleles because all the genes are assorted independently in gametes.
This independent assortment of traits leads to some new combination of characteristics in the offspring. Therefore the correct answer is independent assortment.
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules like surgars
