A student looks at the daughter cells that result from a process of cell division. Which evidence would support that the process is meiosis? A. The daughter cells are larger than the parent cell B. The daughter cells are the same size as the parent cell C, the genetic material in the daughter cells is the same as in the parent cell D. The genetic material in the daughter cells is different than in the parent cell
Answer: C
Explanation: When daughter cells divide, they always pick up most of the genetic materials/features that the parent cell have.

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?
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.
describe the procedure for a civil law trial. what are the possibilities for the outcome of a case?

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.

To what domain does this organism belong?
Domain Eukarya
Domain Bacteria
Domain Animalia
Domain Archeology
Domain Fungi
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).
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%
Explanation:
Punnett squares are in the image

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.

Name some bubonic plague
Bubonic plague is one of three types of plague caused by the plague bacterium (Yersinia pestis). One to seven days after exposure to the bacteria, flu-like symptoms develop. These symptoms include fever, headaches, and vomiting. Swollen and painful lymph nodes occur in the area closest to where the bacteria entered the skin. Occasionally, the swollen lymph nodes, known as "buboes".
Answer:Today, it's best known as the Black Death or the bubonic plague. Medieval people called it "the blue sickness," La pest ("the Pestilence"), and "the Great Mortality." The name bubonic comes from the medieval Latin word bubo via Italian bilbo--meaning a pustule, growth, or swelling.
