TRUE. Roots have tiny root hairs that maximize the plant's ability to absorb water.

Root hairs are found in the exterior of the root called epidermis. They are long membranous extensions from epidermal cells. They increase the surface area of the root thereby maximizing its absorption of water and minerals.

Light is the energy source for plant photosynthesis, particularly sunlight.
Chlorophyll is contained in organelles called chloroplasts.
A by-product of photosynthesis is oxygen.

Stells [14]

Answer:

The common garter snake (Thamnophis sirtalis) is found throughout North America. In the South, it is active year round. In the North, it is active during the warmer months but hibernates during the winter. It is commonly found basking on warm rocks during cool mornings. This lifestyle indicates that the snake is probably <u>heterothermic</u>.

Explanation:

Being heterothermic, like all reptiles, garter snakes bask in the sun to regulate their body temperature. During brumation (the reptile equivalent of hibernation), garter snakes typically commonly den together. Sometimes there will be as many as 100 snakes in one cave. A large, communal or group site is called a hibernaculum they occupy is called hibernacula. These snakes will migrate large distances to brumate.

Snakes do not actually hibernate, rather they become less active during cold weather. It is called "brumation."  Brumation is an extreme slowing down of their metabolism. Snakes are awake, but just very lethargic so you don't see them moving around.

During fall, snakes go back to the previous year’s den. When a sudden cold catches them before they get there, they may die if not fortunate enough to  find a suitable secondary den. They usually do not stay long at the den entrance, but hurry in for the long winter sleep.

Cold-blooded animals like snakes, fish, frogs, and turtles need to spend the winter inactive, or dormant,  because they have no way to keep warm. Snakes will crawl into any area free from frost such as caves, hollow logs, holes under trees and stumps, under wood piles, in other animal's burrows, and occasionally in a person's basement.

VikaD [51]

No there is no selective pressure that confers an advantage to those who do taste it.

<h3>What is PTC?</h3>

Despite the fact that PTC isn't found in nature, tasting other bitter substances—many of which are toxins—that do occur naturally has a high correlation with taste sensitivity.

In order to defend themselves from being eaten, plants develop a range of harmful substances. Early humans developed the capacity to distinguish bitter tastes as a safeguard against ingesting dangerous plants. There are roughly 30 genes in humans that produce bitter taste receptors. People may taste a large variety of bitter substances because each receptor can interact with a number of different molecules.

How many glucose molecules are made during one cycle of photosynthesis?
kondaur [170]
In the calvin cycle, glyceraldehyde-3-phosphate (G3P) is first and foremost responsible for making glucose. To make one G3P molecule, you need three turns of the calvin cycle. In the GP3 molecule, you hade 3 fixed carbon atoms. So to make a six-carbon glucose molecule, you need two GP3 molecules. Therefore it takes 6 turns of the calvin cycle (photosynthesis) to make a glucose molecule.
