Stem cell term applies to muscle cells.
What are the functions of stem cells?Stem cells are the cells that develop into blood, brain, bones, and all of the body's organs. They have the potential to repair, restore, replace, and regenerate cells, and could possibly be used to treat many medical conditions and diseases.
While they can regenerate themselves in an animal or person they are generally very difficult to grow and to expand in the laboratory. Because of this, it is difficult to obtain sufficient numbers of many adult stem cell types for study and clinical use.
Stem cells originate from two main sources: adult body tissues and embryos. Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques.

Larger lions have 15,000 kcal on average to expend per day and need to gain more than that to survive. If lions can only hunt less than 3 times per day, explain how lions obtain food with the lowest cost and greatest energy benefit.
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.

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.
What sodium potassium pump do?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.

A scientist concludes that genetic inheritance of a mutated (changed) gene, such as a gene change that creates different-colored organisms in a population, is more beneficial to an organism over time and contributes to biological fitness. Discuss why a scientist would make that claim.
Answer:
If there is a change in the gene, this can further create a new generation of organisms with this change. With certain changes, it enables organisms to survive in other conditions.

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

6H2O has _ hydrogens total.
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.
