Biology

Anettt [7]3 years ago

Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. Duplication of the genetic information occurs by the use of one DNA strand as a template for formation of a complementary strand. (There’s a picture below of a DNA strand )

Immediately following the arrival of the stimulus at the axon terminal there is a short period called the ________ period during
slega [8]

Answer:

Immediately following the arrival of the stimulus at the axon terminal there is a short period called the latent period.

Explanation:

When a stimulus reaches the terminal of an axon, a period known as the latent period begins. This period has a short duration and during it it is possible to observe the blockage of new stimuli in the nerve fiber. Thus, the new stimuli fail to trigger an impulse and no muscle tension to be observed.

While the latent period is not finished, the neurotransmitter is released through the action of exocytosis that moves until it gets access to the receptor capable of activating the muscle cell.

What use are the descending branches of glacial plants to them?​
kupik [55]

Answer:

Explanation:

A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow under stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques, moraines, or fjords. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that forms on the surface of bodies of water.

What differentiates anthropocentric and biocentric views of the environment?
Dafna11 [192]
If we were to differentiate anthroprocentric and biocentric views of the environment you could say that anthroprocentric is more holistic than biocentric. They consider the importance of the environment to human beings. Biocentric sees humans as an individual part of the environment.

Also Biocentric views tend to focus more on biotic factors (living things) and anthroprocentric veer towards the abiotic factors (non-living things).
