The answer is the first one: vasodilate.

Explanation:

  • Vasodilate: This is the correct answer. When body temperature increases, the blood vessels in the dermis (the layer of skin beneath the epidermis) will vasodilate, or widen. This process increases blood flow to the skin, allowing more heat to be released from the body, which helps to cool it down.
  • Vasoconstrict: This is incorrect. Vasoconstriction is the narrowing of blood vessels, which reduces blood flow to the skin and helps to conserve body heat. This process typically occurs when the body is trying to retain heat, not when it is trying to cool down.

In summary, as body temperature increases, the blood vessels of the dermis will vasodilate to help dissipate heat.

Arrange the steps involved in fluorescence in situ hybridization (FISH) in the correct order, placing the first step at the top. Treat cells with agents that cause them to swell and fix them onto a slide. Denature chromosomal DNA. Hybridize chromosomal DNA to single-stranded DNA probes containing biotin. Add fluorescently labeled avidin. View with a fluorescence microscope.

The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H2O). Note: "major" chemical species are those present in concentrations greater than 10^-6 mol / L. compound formula major species present when dissolved in water --------- methanol CH3OH propylene glycol C3H6(OH)2 glycerol C3H8O3

My 6 kg cat wants to push his box of kitty chow off the table so it will spill a snack for his afternoon "tea". The box has a mass of 1 kg (that's 2.2 lb or 9.8 N of gravitational downward force) and the coefficient of friction with the table top for both kitty paws and box is 0.25 . About how much force does he have to push with to get the box to begin to slide? Pick the closest answer to what you calculate using your understanding of static frictional forces. (A) 15 N (B) 25 N (C) 2.5 N (D) He will slide before the box does (E) 2.2 lb (F) 9.8 N Continue Last saved 4:59:46 PM
