In the summer the northern hemispher gets the most light and the further north you go or the higher latitude the more daylight you get. The Equator is more half and half. The north pole, the sun never sets.
<span>Winter the further north you go, the more night time you get. Equator is still more or less half and half.</span>
Answers- The correct statements about sea grasses are
1. They act as habitats for many marine species
2. They generate up to 10 liters of carbon a day and add nutrients to the sea. They have huge carbon reserves and posses 10 % of the ocean carbon. Also have much higher carbon holding capacity than forest.
3. They are a source of food for manatees and other herbivores - Sea grass in the major source of food for herbivores in marine environment
4. They are toxic to bacteria and algae and protect other organisms by inhibiting the growth of microorganisms.
Answer:
See Explanation
Explanation:
Higher level taxon indicate larger numbers of sub-taxon. This means that time must have passed, allowing sub-taxon to evolve. Therefore, larger, higher taxon must be older to allow sub-taxon to appear.
Molecules called steroids, which include cholesterol, are membrane components that aid in membrane fluidity.
<h3>What is
steroids?</h3>
A steroid is an organic molecule with four rings arranged in a specific chemical structure that has physiological activity. The two primary biological functions of steroids are as signaling molecules and important cell membrane components that influence membrane fluidity. Animals, plants, and fungus all contain a variety of steroid species. All steroid molecules are made in cells using either lanosterol (opisthokonts) or cycloartenol (plants). Lanosterol and cycloartenol are created via the cyclization of the triterpene squalene.
The majority of the seventeen carbon atoms that make up the steroid core structure are arranged in three six-member cyclohexane rings (rings A, B, and C in the first picture) and one five-member cyclopentane ring (the D ring). The degree to which these functional groups are entangled with this four-ring core.

Enzymes are catalysts that speed up chemical reactions in the human body.
<h3>What do you mean by Catalysts?</h3>
Catalysts may be defined as those substances that enhance the rate of chemical reactions without being consumed in them.
Enzymes are also considered as catalysts in the body of living organisms. Basically, enzymes are proteins that assist in the speeding up of any chemical reaction in living entities.
Therefore, enzymes are catalysts that speed up chemical reactions in the human body.
