dominant. If a true breeding pink flower is crossed with a carrier pink flower, what is the
probability in a percentage) that their offspring will be born as carriers for the white
flower trait? Use a Punnett Square to justify your answer

Answers

Answer:

There's no such thing as a carrier pink flower, as pink is a dominant trait. Only carrier white flowers are possible because white is recessive.

If you meant carrier white flower, the percentage of offspring born as carriers for the white flower trait is 50%

D. Genes are_______ present in a cell, but present in viruses.
1. Never
2. Sometimes
3. Always

Answers

Answer:

A. RNA polymerase is always present in a cell, but sometimes present in viruses.

B. tRNA is always present in a cell, but Never present in viruses

C. Ribosomes are always present in a cell, but Never present in viruses.

D. Genes are always present in a cell, but always present in viruses..

Explanation:

A. RNA polymerase is always present in a cell, but sometimes present in viruses. RNA polymerase is the enzyme responsible for transcription in eukaryotic cells, it is the enzyme that stimulates transcription, that is, the passage from DNA to RNA. All RNA viruses encode in their genome an RNA-dependent RNA-polymerase (RdRp) that acts as a catalytic subunit, along with other viral and cellular proteins, in the replication of the viral genome. B. tRNA is always present in a cell, but Never present in viruses Transfer RNA is a type of ribonucleic acid that is responsible for transporting amino acids to ribosomes where, according to the sequence specified in a messenger RNA (transcribed, in turn , from DNA), proteins are synthesized. C. Ribosomes are always present in a cell, but Never present in viruses. Ribosomes are responsible for the granular appearance of the cytoplasm of cells. It is the most abundant organelle, several million per cell. Viruses do not have cytoplasm or ribosomes (elements necessary to form a cell), so they cannot multiply on their own and they need to infect the cell of another organism to do so.D. Genes are always present in a cell, but always present in viruses.Genes are the storage units of genetic information, they are fragments / segments of DNA that encode a specific functional product. Viruses are small pieces of RNA (ribonucleic acid) or DNA (deoxyribonucleic acid), many are encapsulated in an envelope made of base of proteins known as capsid, others protect their genetic material with a membrane or envelope derived from the cell they infect and some others also surround their capsid with a cell membrane. RNA viruses bring with them their own genetic information copying machines (eg, RNA polymerase enzyme) or possess genes (genetic information) that produce the proteins required to assemble the copying machines within the cell that they infect, thereby which makes them independent of the cellular machinery and capable of infecting cells that are not actively reproducing.

Answers

I would say put up a warning sign.

Explanation.
If you used a pesticide on a windy day it’s gonna blow the product around so it might go into the places you wanted it
Having pets around certain pesticides when they are freshly sprayed can be very harmful to an animal.
And typically the recommended dose is correct so there’s no reason to use more

PLEASE HELP!!! How many ATP can we get from one molecule of phosphocreatine?
a.1
b.2
c.10
d.32​

Answers

answer: b. 2
explanation: took the test

Phosphocreatine is a chemical compound that provides high energy to the skeletal muscles. One molecule of phosphocreatine produces one ATP molecule. Thus, option a is correct.

What is phosphocreatine?

The phosphocreatine system is a way to generate ATP and energy in the body (muscles). During muscle contraction, the phosphocreatine yields a phosphate molecule that in turn produces ATP.

The phosphocreatine system provides quick and fast energy in the form of ATP molecules through the anaerobic system that does not require oxygen. It gives its phosphate group to ADP to produce ATP as,

ADP + phosphocreatine → ATP + Creatine

The ATP-PC system yields only one molecule per phosphocreatine at a very fast rate for the muscles to utilize when doing any exercise or physical activity that involves contraction and relaxation.

Therefore, phosphocreatine produces 1 ATP.

To what domain does this organism belong?
Domain Eukarya
Domain Bacteria
Domain Animalia

Answers

Answer:

Domain Eukarya

Explanation:

It sort of looks like a seahorse. And if it happens to be a seahorse, it would belong to the domian eukarya because animals are made of animal cells, and a eukaryotic cell can be either animal cell or plant cell. So it only makes sense for it to belong to domain eukarya (only if it is animal/plant).

In dolphins, to have spots on the skin is a recessive trait. One spotted dolphin and one solid gray dolphin have a baby spotted dolphin. Go through the following steps to figure out the genotype of the parent dolphins.

1) what is the genotype of the spotted (recessive) parent?

Answers

Answer:

the spotted parent has the genotype ss

Explanation:

we will use s as the letter when describing the spotted trait.

since spotted is recessive, that parents have to have two little s to have the trait. Since the child also has that, we know that they will have the genotype ss.  the child would have to get a little s from both parents, so the solid parent would have Ss, showing as solid, but still having the gene for spots.
