Answers
Answer:
By comparing a fossil to similar rocks and fossils of known ages, relative dating can be used to estimate its age. Absolute dating is a method of determining the precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil itself or, more commonly, the rocks that surround it.

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%

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.

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

You perform an experiment using an aquatic plant to determine which color of light is most effective at driving photosynthesis. You take three plants, immersed under water, place plant A under blue light, plant B under red light, and plant C under green light. You notice bubbles coming off the leaves. More bubbles are coming from plants A and B, than plant C. How do these results determine which color of light is most effective at driving photosynthesis
Answers
Answer:
The plants producing more bubbles indicates that photosynthesis is more effectively driven by BLUE AND RED LIGHTS.
Please find explanation below.
Explanation:
According to this question, an experiment is being carried out to determine which color of light is most effective at driving photosynthesis. Three sets of aquatic plants (plants A, B and C) are used for this experiment. Plant A was placed under blue light, plant B under red light, and plant C under green light.
Photosynthesis is the process whereby plants manufacture their food (glucose) using sunlight energy. However, it is worthy to note that OXYGEN GAS is one of by-products of this metabolic process. Hence, as stated in this question, the bubbles noticed to be coming off the leaves is OXYGEN gas.
However, more products in a reaction denotes the fast rate of such reaction. Plants A and B produced more bubbles than plant C. This means that photosynthesis in plants A and B, which released more OXYGEN GAS as BUBBLES, is more effective under the blue and red light respectively.

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.
