How are molecules transported across cell membrane against the concentration gradient?.

Biology

Masja [62]2 years ago

Answer: "To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells."

Kelly, who is blind, switches on the fan in her room without anyone's help. she is able to do this because the Somatic nervous system relays the relevant information to her brain.

<h3>Nervous system :</h3>

According to the classical doctrine of the nervous system, an animal's nervous system is a highly sophisticated component that coordinates its movements and sensory data by sending and receiving signals to and from various regions of its body.

<h3>Somatic nervous system :</h3>

The somatic nervous system, also known as the voluntary nervous system, is the area of the peripheral nervous system responsible for the voluntary control of skeletal muscle movement.

A part of the peripheral nervous system called the somatic nervous system is responsible for the voluntary control of skeletal muscle movement.

<h3>Example somatic nervous system</h3>

The cranial nerves, which transmit information from the brain to the head and neck region, are an illustration of the somatic nervous system. In this area, conscious motor functions are under the control of the somatic nervous system.

Please help me i don’t understand

1. Biogeography, the study of the geographic distribution of plants, animals, and other forms of life. It is concerned not only with habitation patterns but also with the factors responsible for variations in distribution.

2. weathering and other natural forces break down the substrate, rock, enough for the establishment of certain hearty plants and lichens with few soil requirements, known as pioneer species. These species help to further break down the mineral-rich lava into soil where other, less hardy species can grow and eventually replace the pioneer species. In addition, as these early species grow and die, they add to an ever-growing layer of decomposing organic material and contribute to soil formation. This process repeats multiple times during succession. At each stage, new species move into an area, often due to changes to the environment made by the preceding species, and may replace their predecessors. At some point, the community may reach a relatively stable state and stop changing in composition. However, it's unclear if there is always—or even usually—a stable endpoint to succession.

3. I don’t have the video so I’m going to take. Wild guess. Just look up types of finches

4. Broadly speaking, different species are unable to interbreed and produce healthy, fertile offspring due to barriers called mechanisms of reproductive isolation.
These barriers can be split into two categories based on when they act: prezygotic and postzygotic.

I tried my best hope this helps :)
