Which of the following best describes the relationship between variations and adaptations?A. All variations are adaptations, but not

A

Explanation:

1-Caves to helps bears hibernate, trees to help birds sleep, and webbed feet to help duck

2-long necks of giraffes to helps eat form tall trees, the streamlined bodies of aquatic fish and mammals, the light bones of flying birds and mammals.

3- A adaptaiona plants may have are they are able to live in the water underground or on land, a pores in leafs and/or plants, vascular tissue in plants that has water and dissolved nutrients, and underground organ that some plants have.

4- the specimens of making a scientific name are the first part of the name is genus (plus the genus is always capitalized) and the second part of the scientific name is that is the species

Explanation: hope this is what u were looking for

B)

Explanation:

B

Explanation:

Chloroplasts are the ’solar energy plants’ of a cell – they convert light energy into chemical energy

This chemical energy may be either ATP (light dependent) or organic compounds (light independent)

Only photosynthetic tissue possess chloroplasts (e.g. is present in leaves but not roots of plants)

Chloroplasts are thought to have once been independent prokaryotes that were internalised by eukaryotes via endosymbiosis

They have a double membrane structure (due to vesicular coating as part of the endocytotic process)

They have their own DNA (circular and naked) and ribosomes (70S)

Their metabolic processes are susceptible to certain antibiotics

The structure of the chloroplast is adapted to the function it performs:

Thylakoids – flattened discs have a small internal volume to maximise hydrogen gradient upon proton accumulation 

Grana – thylakoids are arranged into stacks to increase SA:Vol ratio of the thylakoid membrane

Photosystems – pigments organised into photosystems in thylakoid membrane to maximise light absorption

Stroma – central cavity that contains appropriate enzymes and a suitable pH for the Calvin cycle to occur

Lamellae – connects and separates thylakoid stacks (grana), maximising photosynthetic efficiency

Explanation:

please mark me as brainliest

D

Explanation:

I think

I think its C

Explanation:

The adaptions of the chloroplast are thykalods which increases hydrogen gradient protons, it also has pigments that make light rlly large which is called photosystems :3

A- the antlers and horns are structural adaptations. The fighting is a behavioral adaptation.
Antlers and horns are physical adaptations that some mammals have acquired over time. However, fighting is not a physical feature but a behavioral adaptation used to beat other males during mating season.

i believe the correct answer is Adaptations increase the probability of an organism surviving and reproducing in a specific environment.

the burning of fossil fuels releases carbon dioxide and other greenhouse gases.good luck! =)cutie~
