Plants and other autotrophs make food out of “thin air”—at least, they use carbon dioxide from the air to make food. Most food is made in the process of photosynthesis. This process provides more than 99% of the energy used by living things<span> on Earth. Photosynthesis also supplies</span>Earth's atmosphere<span> with </span>oxygen<span>.

The receptors for steroid hormones are located inside the cell instead of the membrane surface like most other signal receptors.
Furkat [3]

The steroids gain access to their receptors because steroid hormones are lipid soluble and can readily diffuse through the lipid bilayer of the cell membrane.

The steroid hormone dissociates from its plasma carrier protein and diffuses throughout the mobile membrane. After gaining entry to the mobile, the free hormone binds to an intracellular receptor and alters gene transcription.

In keeping with the free hormone speculation, due to their hydrophobicity, steroids are able to freely diffuse across lipid bilayers; but, megalin-established endocytosis has been proven to be at the least partly answerable for the uptake of sex hormones and nutrition D.

Steroid hormones, in general, are believed to freely diffuse across a membrane partly due to their close resemblance to ldl cholesterol, but recent evidence indicates that they could additionally enter cells thru receptor-mediated endocytosis.

Helppppppp Pleaseeeee

Answer: Beaks---->Evolution, Natural Selction, Genetic Drift, Behavioral Isolation, n Non-random mating...

Explanation:

Darwin observed many discoveries like the Galapagos tortoises, iguanas, penguins, crabs, etc...But one of the most important ones that definitely helped to see the evolution and the process of natural selection is the Galapagos finches they changed a lot mainly because of environmental changes. The Galapagos Islands are special to evolutionary history firstly because there are a lot of different sizes and colors in birds but the main focus was that after Earth was a Pangea, all land united, genetic drift occurred in the Galapagos island meaning that a small population was 'trapped' inside with no way of getting new traits though that's not exactly right because we not only change genetically but also by environmental changes and humans change it too of course(like hunting). Another important discovery that was found there wasn't only hints of evolution and natural selection but also behavioral changes especially in mating, some birds sing or dance it really depends but if some animals don't mate then new species are formed that's one of the reasons why it created a lot of diversity; Another reason to the topic of reproduction is non-random mating, some organisms are looking for some specific location or phenotypes in their mates if they don't find it they look for them in their own species which can cause the extinction of that species or spread it.

How do animal cells maintain an appropriate water balance; how do they maintain homeostasis
marshall27 [118]

Answer:

Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body functions.
