Negative feedback: If the body temperature is high, the rate of perspiration (sweat) should
A. increase
B. decrease
Answer:
I believe it would decrease
Explanation:
The high temperature will be detected by sensors—primarily nerve cells with endings in your skin and brain—and relayed to a temperature-regulatory control center in your brain. The control center will process the information and activate effectors—such as the sweat glands—whose job is to oppose the stimulus by bringing body temperature down.
rate of reproduction to sexual reproduction in plants
Answer: Asexual reproduction
For example, sexual reproduction allows for variation, but gestation usually takes a long time and it requires heavy parental input. Asexual reproduction occurs quickly, but because all of the offspring have the same genetic information, individuals are more susceptible to disease.
Explanation:
Why is a feather non living? Give detailed explanation. Thanks
Answer:
feathers are dead tissues. They are only alive while developing as they have a blood supply. Feathers are produced by living cells located in small pit-like follicles in a bird's epidermis, its outer skin layer. The feather is enlarged by the keratin that is protruding straight out from the skin follicle. In order for something to be classified as anything that was never alive

Edwin Chargaff was a 20th century biochemist who investigated the structure of DNA. Chargaff looked at the ratios of the four bases in the DNA. State the type of bond that joins the bases together in a DNA molecule
Answer:
Hydrogen Bond
Explanation:
The hydrogen bond joins bases together in a DNA molecules. Which is the bond between two strands on a DNA molecule. Although the hydrogen bond is weak, collectively in the DNA molecule, it is a strong bond which binds the molecule together.
How do the nutrients necessary for plant growth get into the soil?

As with glycolysis, fermentation takes place in the cytoplasm of the cell. There are two different forms of fermentation—lactic acid fermentation and alcoholic fermentation.
This diagram represents the cell cycle. When cells leave the cell cycle, they exit during G1 phase and then enter G0 phase, a resting period. Most normal cells can leave G0 phase and reenter the cell cycle at G1 phase before entering S phase. Cancer cells are different because they cannot enter G0 phase and are likely to do which of the following?
A Fail to complete S phase
B Continuous unregulated cell division
C Mutate during G phase
D Die after completing mitosis
