Four friends were talking about human DNA, genes, and chromosomes. They each had different ideas about where these structures we

re found. This is what they said.
Bella: "I think DNA is found on genes."
Kyra: "I think chromosomes are found on genes."
Kurt: "I think genes are found on DNA."
Joan: "I think chromosomes are found on DNA."

Who is correct? Explain why you think so.

Kurt: " I think genes are found on DNA." Because genes are actually coded by the base sequence of a DNA strand.

FinnZ [79.3K]
<h3> It is a protein that pulls water into my blood vessels.</h3>

Explanation:

Hypovolemic shock is a life threatening condition that results in severe dehydration of the body or extreme blood loss. Hypovolemic shock causes blood volume to decrease to an extent where heart is unable to pump it.

Hypovolemic shock is such a critical condition where multiple organ failure may occur. It is often treated with intravenous rehydration therapy.

Serum albumin is a common compound which is given to a shock victim as it has the capability of pulling water into the body hence, restoring the blood volume.

So when patient says that "It is a protein that pulls water into my blood vessels." Shows that he understood what nurse taught her.

How many variations do you observe?
masya89 [10]

Answer:

Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behaviour, learning and mental ability, and other obvious or measurable characters.

chromosomes or by differences in the genes carried by the chromosomes. Eye colour, body form, and disease resistance are genotypic variations. Individuals with multiple sets of chromosomes are called polyploid; many common plants have two or more times the normal number of chromosomes, and new species may arise by this type of variation. A variation cannot be identified as genotypic by observation of the organism; breeding experiments must be performed under controlled environmental conditions to determine whether or not the alteration is inheritable.

Genotypic variations are caused by differences in number or structure of Environmentally caused variations may result from one factor or the combined effects of several factors, such as climate, food supply, and actions of other organisms. Phenotypic variations also include stages in an organism’s life cycle and seasonal variations in an individual. These variations do not involve any hereditary alteration and in general are not transmitted to future generations; consequently, they are not significant in the process of evolution.

3. How would you date a sample of rock that you suspect as being one of the earliest on Earth? (1 point)
Kay [80]
<span>If I were attempting to date a rock sample that I suspect to be incredibly old, i would use radioactive isotopes with a long half life. When dating rocks and fossils to discover approximately how old they are, radioisotope dating is used on igneous rocks found near fossils. Things like Uranium 235, which is an unstable radioactive isotope of elements, decays at a constant rate over time so can be useful in determining age.</span>
