What is the constellation made up of?

1 answer:

4 0

A constellation is a group of stars that make an imaginary shape in the night sky. They are usually named after mythological characters, people, animals and objects. In different parts of the world, people have made up different shapes out of the same groups of bright stars.

How the climatic zones of the planet influence rhythmic and seasonal changes

Explanation:

The Earth is tilted 23.5 degrees on its axis, which affects the distribution of the sun’s energy across the surface of the planet. As the Earth orbits the sun every 365 ¼ days, the axis is always pointing in the same direction into space, with the North Pole toward Polaris, the North Star. Around June 22, the northern hemisphere is angled towards the sun, and receives the most direct radiation and the most energy. This is the start of astronomical summer in the northern hemisphere and winter in the southern hemisphere.

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one

netineya [11]

Answer:

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another , this happens because the two sides of a cell membrane face different environments and carry out different functions.

Explanation:

PROTEINS , LIPID AND CARBOHYDRATES , all are the components of the plasma membrane , located at different sites .

PROTEINS -: The main component of plasma membranes is proteins. Two key categories of membrane proteins are available: integral and peripheral. As their name implies, integral membrane proteins are incorporated into the membrane: they have at least one hydrophobic region that anchors them to the phospholipid bilayer's hydrophobic center. Others just stick partway through the membrane, while others extend from one side of the membrane to the other and on either side are exposed.

On the outside and inside surfaces of membranes, peripheral membrane proteins are found which are bound either to integral proteins or to phospholipids. Peripheral membrane proteins do not stick into the hydrophobic center of the membrane as opposed to integral membrane proteins, and appear to be more loosely bound.

LIPID -: Phospholipids, arranged in a bilayer, make up the plasma membrane 's essential cloth. Since they are amphipathic, they are well-suited for this function, meaning they have both hydrophilic and hydrophobic regions.

The hydrophilic or "water-loving" component of a phospholipid is its head, which includes a phosphate group that is negatively charged, as well as an additional small group that can also be charged or polar.

Its long, nonpolar fatty acid tails make up the hydrophobic, or "water-fearing," portion of a phospholipid. The tails of fatty acids can interact easily with other non-polar molecules, but interact poorly with water.

CARBOHYDRATES -: The main component of plasma membranes is carbohydrates. In general, they are located on the outer surface of the cells and are either bound to proteins (glycoproteins forming) or to lipids (glycolipids forming). These chains of carbohydrates can consist of 2-60 units of monosaccharide and can either be straight or branched.

Hence , the correct option is B.

describe the five cellular targets of antibiotics, and explain antibiotics are effective against bacteria but not viruses.

soldier1979 [14.2K]

Five cellular targets of antibiotics were exploited withinside the improvement of antimicrobial drugs: cell wall synthesis, protein , ribonucleic acid , (DNA) , and middleman metabolism.

<h3>How do antibiotics acts as resitance?</h3>

The principal mechanisms of resistance are: proscribing uptake of a drug, amendment of a drug target, inactivation of a drug, and lively efflux of a drug. These mechanisms can be local to the microorganisms, or received from different microorganisms.

In principal, there are 3 principal antibiotic objectives in bacteria: The cell wall or membranes that surrounds the bacterial mobileular. The machineries that make the nucleic acids DNA and RNA. The equipment that produce proteins (the ribosome and related proteins).

Neurons normally derive ATP solely through

WARRIOR [948]

Answer:

A. Aerobic respiration

Explanation:

The cell body of neurons have mitochondria which in turn serve as the site for ATP production. Nerve cells derive their energy by complete oxidation of glucose by the process of aerobic respiration. The enzymes required for aerobic respiration of glucose are present in mitochondria. The ATP molecules produced in cell bodies are delivered to the other parts of neurons to serve as source of energy during conduction of nerve impulse.
