Answer:

Here is basic information: "Stem cell therapy for the heart; several different types of approaches are being used to repair damaged heart muscle with stem cells. The stem cells, which are often taken from bone marrow, may be inserted into the heart using a catheter. Once in place, stem cells help regenerate damaged heart tissue

In a plant called jimsonweed, flowers can be white or purple. A jimsonweed plant with white flowers is crossed with a jimsonweed

STALIN [3.7K]

Answer:

Although statements are not given in the question, we could make the most possible deduction as follows:

The allele for purple flowers is dominant whereas allele for white flowers is recessive.

Explanation:

According to the question,

Purple flower plant was crossed with white flower plant.
All offsprings have purple flowers.

Here we have one possibility that both parents were homozygous but in their own traits. Purple flower plants were "PP" and white flower plants were "pp" So, the first progeny (direct offsprings) would have "Pp". So, as per considerations, purple is dominant allele which will mask the recessive allele thus defining the color of all offsprings as purple. However, further cross of their generation will definitely end up into purple and white flowers (3:1) but this condition is not mentioned in the statement.

muminat

The carbon cycle is one of earths natural resources that enables all living organisms to inhabit the planet. For example, with out this vital resource we would run out of oxygen. Flora (plants and trees) use the carbon that is a by product of cellular respiration by fauna (humans and animals) to reproduce oxygen and this cycle continues. which is what keeps all living organisms in harmony and alive.

Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN

Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

In any one species, the amount of adenine closely approximates that of thymine.
In any one species, the amount of guanine closely approximates that of cytosine.
The amounts of A, T, G, and C in DNA varies from species to species.

(options A, B and D)

Explanation:

Organizing the data has to:

Source of DNA A T G C

Streptococcus 29.8 31.6 20.5 18.0

Yeast 31.3 32.9 18.7 17.1

Herring 27.8 27.5 22.2 22.6

Human 30.9 29.4 19.9 19.8

E. Coli 24.7 23.6 26.0 25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.
