<span>Human skin is one of the more important cooling systems. Unlike many other mammals, humans have sweat glands. These cool the surface of the skin by evaporating water. Body heat is carried to the surface of the skin by the circulatory system. Humans also have finer hair than other animals. We are actually as hairy as chimpanzees, but our hair is so fine it makes us appear to have none. This lack of dense hair allows the skin to evaporate sweat more efficiently. Another human cooling mechanism is our posture. Walking upright means only a small portion of the body is exposed to direct sun during the hottest part of the day. Our ancestors were thought to scavenge during this period because preditors had to escape the sun. Walking on 4 legs meant the entire surface of the back was exposed to the sun.A uniquely human adaptation to heat is the scalp. Blood vessels run directly from the surface of the brain through pores in the skull and out across the head and face. This serves to cool the brain. Humans have enromous brains which generate quite a lot of heat. This system of veins serves like a kind of radiator, keeping the brain from overheating. It also explains why head injuries tend to bleed so profusel</span>
Biomolecules are made up of building block monomers (the most abundant elements in biological monomers are carbon, hydrogen, and oxygen)
The answer is C, loss of biodiversity due to an invasive species
Answer:
B. bb x bb
Explanation:
Your answer is B because all the other options will have you end up with at least one brown, and bb x bb would have only blue because it is 100% recessive.
I hope it helps you! Have a great day!

You are familiar with the electron transport system in photosynthesis
that takes light energy and converts it to chemical bond energy in the
form of ATP and NADPH. This electron transport chain in cellular
respiration will take the energy stored in NADH and FADH2
during the Krebs cycle and convert it to chemical bond energy in the
form of ATP. In eukaryotes, this reaction takes place on the inner
mitochondrial membrane, as is shown in Figure 4.26. Prokaryotes that
undergo aerobic respiration also have an electron transport chain
located within their plasma membrane, which may be highly folded similar
to the inner membrane of the mitochondrion. Thats the answer my friend hope it helps
