2 answers:

When your body temperature rises because of an infection, it's called a fever. Fevers are caused by chemicals called pyrogens flowing in the bloodstream. Pyrogens make their way to the hypothalamus in the brain, which is in charge of regulating body temperature.

Which of the following represents organisms in a food chain?

Lisa [10]

Answer: c seeds, mice, snakes

Explanation:

a hawks, owls, eagles NO

These animals all eat some form of meat, and they are on the top of all of their food chains. If you put these animals in a room with no food, there'd be no food chain, and they would got out at each other until there was one left, and there'd be no advatanges because 1. they can all fly and 2. they are all top consumers. The same thing goes for D except hyenas can't fly.

b deer, rabbits, cows NO

This is not a food chain because all of the animals are herbivore, so they only eats plants and will not eat each other.

c seeds, mice, snakes YES

The seeds are a producer which is to be eaten by a consumer (the mouse), and which are then eaten by the predator, the snake.

d hyenas, vultures, crows NO

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

When NADH is the electron donor to the respiratory chain, 2.5 ATP are formed, but when FADH2 is the electron donor, only 1.5 ATP

Fofino [41]

Answer:NADH donates it electron to complex I a higher energy level than other complexes while FADH donates it electron to complex II a lower energy complex.

Explanation:

Both NADH and FADH are shuttle of high energy electrons originally extracted from food into the inner mitochondrial membrane.

NADH donate it electron to a flavoprotein consisting of FMN prosthetic group and an iron-sulphur protein in ETC complex-I. Two electrons and one hydrogen ion are are transferred from NADH to the flavin prosthetic group of the enzyme.

While the electrons from FADH2 enters the ETC (electron transport chain) at the level of co-enzyme Q (complex II). This step does not librate enough energy to act as a proton pump.

So NADH produces 2.5 ATP during the ETC and oxidative phosphorylation because it donates its electron to Complex I, which pump more electrons across the membrane than other complexes.
