A plant species has two alleles for petal color: pink and white. The pink (A) allele is
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%

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.

How would this diagram be
different if it showed anaphase I of meiosis instead of anaphase of mitosis?
A Each chromosome would still have two chromatids.
B The chromosomes would look the same as in mitosis.
C You would be able to see DNA in the chromosomes during meiosis.
D Homologous chromosomes would be moving to the same end of the cell

Answers

Answer:

This question is incomplete as there is no diagram, however, the question can still be answered without it. the answer is as follows:

A. Each chromosome would still have two chromatids.

Explanation:

The ANAPHASE stage of both mitotic and meiotic division is the stage where chromosomes are pulled apart into opposite poles of the cell. However, meiosis occurs in a two-step division tagged meiosis I and meiosis II.

In mitosis, sister chromatids of a chromosome are separated during anaphase, but in meiosis I, homologous chromosomes are pulled apart during anaphase I. This means that in the anaphase I of meiosis as opposed to anaphase of mitosis, each separated chromosome WOULD STILL HAVE TWO CHROMATIDS.

The nucleus' principal jobs include storing the cell's DNA, preserving its integrity, and assisting with transcription and replication.

One of the most noticeable features of a eukaryotic cell is its spherical nucleus, which normally makes up 10% of the cell's volume.

What is DNA recombination?

DNA fragments are broken and recombined during the recombination process to create novel allele combinations. The genetic diversity that results from this recombination process at the gene level reflects variations in the DNA sequences of various organisms.

Recombination happens when two DNA molecules trade genetic material with one another. When homologous chromosomes align in pairs and exchange DNA segments during prophase I of meiosis, one of the most notable instances of recombination occurs.

B- Climate analysis conducted by sampling pollen preserved in amber shows an increase in grass pollen 29 million years ago, which indicates there was an increase in grasslands that correlates to an increase in butterfly speciation during the same time period.

C- There is a correlation between the rapid and wide-ranging decrease in species richness of insects in general 29 million years ago and the increase in species richness and diversity among the butterfly population during the same time period.

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.
