Answer:
they are the place where cell respiration takes place
Explanation:
Cellular respiration is a series of metabolic reactions used by the cell to create energy (ATP), these reactions occur partially in the cytoplasm, but mostly in the mitochondria. On the other hand, vacuoles store water in plants and help give them structure, are the largest organelle in plant cells, and both plants and animals have them. Therefore the answer is, they are the place where cell respiration takes place.

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
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%

A. RNA polymerase is______ present in a cell, but present in viruses.
B. tRNA is________ present in a cell, but present in viruses.
C. Ribosomes are________ present in a cell, but present in viruses.
D. Genes are_______ present in a cell, but present in viruses.
1. Never
2. Sometimes
3. Always
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.

how do scientists use rock layers to date fossils ? USE IN YOUR OWN WORDS.
40 POINTS DONT SKIP !
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.

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

It is now A G C A A C C C G T C T T G G T C G T T G G G C A G A A C C Use your knowledge of mutation and protein synthesis to answer the following questions. What mutation has occurred
The mutation that has occurred is substitution mutation.
Mutation is defined as the random changes in deoxyribonucleic acid (DNA) that alter genetic information, and so can introduce new characteristics.
Mutation can occur in because of the following reasons stated below:
When exposed to environment saturated with ultraviolet light, it can cause cell mutation; andWhen exposed to certain chemical such as free radicals.A typical example of mutation that occurs in DNA is the substitution mutation.
Protein synthesis is the process used by cells to produce usable specific proteins as directed by the DNA.
The base sequence in DNA determines the sequence of amino acid in peptide.
Substitution mutation occurs when one base is incorrectly replaced in the complementary strand of a DNA.
From the DNA base sequence given,
Cytosine replaced Thymine; andGuanine replaced Adenine.This replacement that occurred will lead to abnormal protein synthesis.
