Explain in detail about Phospholipid Bilayer.

Biology

erica [24]3 years ago

5 0

A phospholipid bilayer or lipid bilayer is a double layer of lipids in a cell membrane which has a hydrophobic and a hydrophilic part.

Hydrophobic - expelled by water

Hydrophilic - attracted to water

The layers form the cell membrane which means that it's functions are the same as the functions of a cell membrane, and are critic to the cells functioning.

What structural component gives arteries the ability to passively adapt to changes in blood pressures that accompany the heartbe

Andrews [41]

Answer: elastic fibers

Explanation:

Elastic fibres are the essential durable component present in mammalian connective tissueand functions to provide proper pulmonary, cardiovascular and intestinal system structure and function. Their structural function is to provide elastic recoil and resilience for the tissues.

Elastin fibers ahve two main including microfibrils and elastin containing fibrillin play a mechanical and structural role in the arteries, and their important function is to provide the tissues with resilience and elasticity.

Hence, elastic fibers helps arteries to adapt to changes in blood pressures that accompany the heartbeat.

Why do all the planets in the solar system orbit the sun in the same direction ?

nekit [7.7K]

Answer:

The result of the initial rotation of the cloud of gas and dust that condensed to form the Sun and planets. As gravity condensed the clouds, of angular momentum increased the rotational speed and flattened the cloud out into a disk.

Describe how climate would be influenced if:

madam [21]

The rate of energy coming from the Sun changes slightly day to day. .It has been suggested that changes in solar output might affect our climate—both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes.
The axial tilt angle affects climate largely by determining which parts of the earth get more sunlight during different stages of the year Likewise, during winter for the northern hemisphere, there would be fewer hours of daylight because the northern hemisphere would essentially be pointed away from the sun.
If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere, blocking the radiation from the Sun. This would cause the global temperature to decrease drastically.
The Sun's irradiance has its greatest effect on Earth's upper atmosphere, while the lower atmosphere insulates Earth from the increased heat. If the Sun were driving Earth's warming, one would expect to see that upper atmosphere getting increasingly hot.\

The primary role of _____ is to bind animal cells together.

NNADVOKAT [17]

The primary role of DESMOSOME is to blind animal cells together. It is the formation of a structure from protein plaques in the cell membranes linked by filaments. This links to a the protein that is attached to the cell surface adhesion.

The anterior pituitary receives hypothalamic input through the portal blood supply. what is the advantage of this type of anatom

kotegsom [21]

The advantage of this type of anatomical relationship is that this enables the pituitary to receive signals before sending hormones to the rest of the body through the blood.

The anterior pituitary, a significant component of the endocrine system, is the glandular anterior lobe that, along with the posterior lobe (also known as the posterior pituitary or neurohypophysis), constitutes the pituitary gland (hypophysis).

Stress, growth, reproduction, and lactation are just a few of the physiological activities that the anterior pituitary controls.

Blood tests that assess hormone levels are frequently used to determine if the anterior pituitary and the organs it controls are functioning properly.

The hypothalamus-hypophyseal portal veins deliver hypothalamic releasing and inhibitory hormones directly to the anterior pituitary gland.

Certain hormones from the hypothalamus bind to receptors on particular anterior pituitary cells, controlling how much of the hormone they generate is released.
