Adenosine Triphosphate (ATP) is defined as the energy molecule that is derived from the metabolic oxidation of glucose.

This ATP is used for a variety of processes which include:

Active transport: It provides the energy that is needed to move materials against a concentration gradient. This leads to the transport of the materials across cell membranes.Movements: Muscle contraction and ciliary movement which brings about movement in cells, requires energy from the hydrolysis of ATP.Thermodynamically unfavorable reaction: This can be driven by the hydrolysis of ATP energy molecule in a cell.

5. Adaptation - we all adapt to an environment other species can’t.

The physical characteristics that all specimens have in common can be presence of cells, as there is no specimen given, let's take animals. A dichotomous key can be used to find the similarity.

What is a specimen?

A specimen can be anything that is displayed regarding the subject. In labs the specimens can be chemicals, animals, plants, any objects, etc.

Specimens are displayed to learn about them, to see the actual version of that animal that can not be seen easily.

Explain why stem cell research is a controversial subject. What are some of the sources for stem cells?

Answers

Answer:

Stem cell research is a controversial subject because they are human embryonic stem cell (hESC), and obtaining stem cells involves the destruction of human embryos

Explanation:

The inner cell mass of a 5 to 7-day-old blastocyst can be used to generate pluripotent stem cell lines. Human embryonic stem cell investigation, on the other hand, is morally and politically fraught since it encompasses the killing of human embryos.

What are stem cells?

Stem cells are the primary raw material of the body, the cells that give rise to every other cells with specialized functions.

Under the right circumstances, stem cells differentiate to form the most cells known as daughter cells in the body or in a research lab.

Stem cells are mostly found in bone marrow. This is how they divide in order to produce new blood cells.

Once mature, blood cells end up leaving the bone marrow and reach the bloodstream. A small number of immature stem cells enter the bloodstream.

Bone Marrow has long been thought to be the best source of stem cells.

Previously, if a patient required a stem cell transplant but didn't have access to umbilical cord blood stem cells, they earned a bone marrow transplant.

Thus, this is the reason to have stem cell research as a controversial subject.

Approximately how many mutations occur naturally in DNA per 10,000 bases?
A. 2
B. 2000
C. 200
D. 20

Answers

Explanation:

Modern methods indicate that the mutation rate is roughly one to two mutation per 10,000 genes per generation.

In human cells, approximately TWO (2) MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).

The mutation rate (u) refers to the occurrence of new mutations in a given nucleotide sequence over time.

In human cells, the mutation rate is approximately 10⁻⁴ per generation.

Therefore, in a DNA sequence that has 10,000 base pairs of length, this value is equal to 2 mutations per generation (u = 2 / 10,000 = 10⁻⁴).  

In conclusion, approximately 2 MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).
