Which is one of the contributions that supported the development of the Clean Water Act? ​

Answer:

Fusion

Explanation:

A star's energy comes from the combining of light elements into heavier elements in a process known as fusion, or "nuclear burning". It is generally believed that most of the elements in the universe heavier than helium are created, or synthesized, in stars when lighter nuclei fuse to make heavier nuclei.

Nuclear fusion

Answer:

Confirmed

Explanation:

nutrition is the answer bcz without nutrition the diseases will effect more in a population

Answer:

12

Explanation:

6H2O or hexahydrate is a group of 6 water molecules or 6 molecules of dihydrogen monoxide. When looking for the total particular number of elements in a substance, find the subscript or smaller number in front of that atom, and look out for the coefficient or bigger number of the whole substance, and multiply that coefficient by the subscript to find the total atoms of that element.

Since there are 2 hydrogen's in each molecule of water, 6 molecules would make that a total of 12 hydrogen's for 6 molecules of water.

eukrayotic cell l guess

Explanation:

A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1).

Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1). The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents dehydration. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion, while most pili are used to exchange genetic material during a type of reproduction called conjugation.

Eukaryotic Cells

In nature, the relationship between form and function is apparent at all levels, including the level of the cell, and this will become clear as we explore eukaryotic cells. The principle “form follows function” is found in many contexts. It means that, in general, one can deduce the function of a structure by looking at its form, because the two are matched. For example, birds and fish have streamlined bodies that allow them to move quickly through the medium in which they live, be it air or water.

A eukaryotic cell is a cell that has a membrane-bound nucleus and other membrane-bound compartments or sacs, called organelles, which have specialized functions. The word eukaryotic means “true kernel” or “true nucleus,” alluding to the presence of the membrane-bound nucleus in these cells. The word “organelle” means “little organ,” and, as we learned earlier, organelles have specialized cellular functions, just as the organs of your body have specialized functions

Answer:

Wildebeest and Zebra.

Explanation:

Wildebeest and Zebra are the hunts which gives huge amount of energy and lowest cost of energy because Wildebeest gives 25000 available energy and 10000 energy cost to hunt and 15000 amount of energy remain while Zebra gives 170,000 while 55000 energy spend on the cost to hunt and 115000 is available energy to the lion that is enough for the lion per day energy requirements.

Answer:

False

Explanation:

A cell membrane is not rigid a cell wall is rigid.

Answer:

D.

Explanation:

I looked it up and the first thing I saw was Crabs. I hope this answer helps. :)

By continuously maintaining a state of disequilibrium between the concentrations of Na+ and K+, the sodium-potassium pump regulates the membrane potential of the neuron. He's working with the membranes of crab nerve cells. Thus, option D is correct.

Na-k pump controls the levels of Na+ and K+ throughout the cell membrane.

The concentrations of Na+ and K+ are higher on the inside and outside the cell, respectively, when the cell is at resting membrane potential.

When various ions pass across the neuron membrane, action potentials are produced. Sodium channels first open as a result of a stimulation.

Sodium ions rush into the neuron because there are far more of them on the outside, and because the inside of the neuron is negative in comparison to the outside.

Therefore, crab nerve cells use to study the sodium potassium pump.

Nucleic acid segments and ar

DNA and RNA are nucleic acids that can store biological information based on the sequence of their nucleotide monomers. Figure 1 shows a short segment of each of the two types of nucleic acids. Which of the following best describes a structural difference between DNA and RNA?

A. DNA contains four types of nitrogenous bases, whereas RNA contains only two types of nitrogenous bases

B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose.

C. A DNA molecule is composed of two parallel strands with the same 5'-3' directionality, whereas an RNA molecule is composed of only one strand

D. Phosphate groups provide rigidity to DNA, but RNA is flexible and contains no phosphate groups

Answer:

B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose.

Explanation:

A. DNA contains four types of nitrogenous bases, whereas RNA contains only two types of nitrogenous bases - this is false. Both contain four types of nitrogenous bases. DNA contains cytosine, guanine, adenosine and thymine, whereas RNA contains cytosine, guanine, adenine, and uracil.

B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose. - this is true, each nucleotide in DNA contains a deoxyribose sugar, whereas each nucleotide in RNA contains a ribose sugar

C. A DNA molecule is composed of two parallel strands with the same 5'-3' directionality, whereas an RNA molecule is composed of only one strand - this is false. DNA is composed of 2 strands, and RNA is composed of one, but the DNA strands run in an anti-parallel configuration (one runs 5'-3', the other runs 3'-5')

D. Phosphate groups provide rigidity to DNA, but RNA is flexible and contains no phosphate groups - this is false, both DNA and RNA nucleotides contain phosphate groups
