Plants perform cytokinesis differently than animals becausea. plant cytokinesis takes place during interphase but animal cytokinesis takes place in cell division.
b. plant chromosomes are more difficult to separate than animal chromosomes.
c. the rigid cell wall of the plant cell prevents the plasma membrane from pinching inward like it does in animal cells.
d. the centrosomes of plants do not replicate prior to cell division.

Answers

Answer 1

Answer: Plants perform cytokinesis differently than animals because plant cytokinesis takes place during interphase but animal cytokinesis takes place in cell division.
> Unlike animal cells, plant cells have a cell wall which needs to be divide or split up.
>Mitosis and cytokinesis are two different things; mitosis is the division of the components of the nucleus, whereas cytokinesis is the division of the
cytoplasm and its constituents.

Thus, the answer is letter A.

How are photosynthesis and cellular respiration related

Answers

The answer is Cellular respiration breaks down glucose while photosynthesis produces glucose (Apex)

each process makes what the other needs
photosynthesis uses water and carbon dioxide and it makes glucose and oxygen. cellular respiration uses glucose and oxygen and make water and carbon dioxide.
as well as, photosynthesis builds sugars that respiration breakdown.

What is common between aerobic and anaerobic respiration?

Answers

Both aerobic and anaerobic respirations are types of cellular respiration. Both use glycolysis to produce ATP. Both generate energy by breaking down glucose. Both produce byproducts and depend on chemical reactions that are localized in the cytosol. Both use pyruvate as a substrate and both processes depend on enzymes to catalyze their respective chemicalreactions.A fact about these two types of respiration is that aerobic respiration produces or release 19 times more energy than anaerobic respiration from the same amount of glucose

(a) Describe the process in meiosis that ensures that both maternal and paternal chromosomes are passed on to each spermatozoon.

Answers

Answer:

Explanation:

Meiosis is a type of cell division in which the ploidy of the organism reduces to half in the daughter cells.

Meiosis produces 4 daughter cells from 1 parent cell with a different combination of the genetic material but haploid chromosomes.

The meiosis process takes place in two stages in which during the first stage, the homologous chromosomes separate reducing the chromosome number to half that is from diploid chromosomes of parents to haploid in daughter.

Since the process of meiosis form haploid gametes in both male and female therefore after fertilization restores the diploid chromosomes of the parent cell and form a diploid structure.

Which of the following is a result of a change in pressure?a. Frost wedging
b. Oxidation
c. Exfoliation
d. Chemical feathering

Answers

The answer is C. The type of weathering that occurs due to changes in pressure drop is a mechanical type. Exfoliation is one type of mechanical weathering where rocks weather by peeling off in sheets. Rocks underneath are under high pressure from underlying rocks. Also, these rocks are experiencing progressively lower pressure from overlying rocks. This creates tension due to unbalance force. Crack formation relieved this tension which will eventually result to exfoliation.

The third step in the scientific method is reviewing the literature.Question 10 options: a. True
b. False

Answers

Reviewing the literature is not a specific step in the scientific method but an ongoing process integral to research, helping shape hypotheses and guide experiments. So the statement is false.

The statement that the third step in the scientific method is reviewing the literature is generally "False."

The scientific method is a systematic approach to conducting scientific research and typically involves steps like observation, hypothesis formation, experimentation, data analysis, and conclusion.

While reviewing the existing literature is a crucial component of scientific research, it is not typically considered a distinct step within the method. Instead, it is an ongoing and integral part of the research process that can occur at various stages.
Scientists often begin their research by reviewing relevant literature to understand what is already known about the topic, identify gaps in knowledge, and formulate research questions or hypotheses. This literature review helps guide the research design and methodology.

Therefore, while reviewing the literature is essential, it doesn't fit neatly into a specific step of the scientific method but rather supports and informs the entire research process.

Final answer:

The claim that the third step of the scientific method is reviewing literature is false. The third step is forming a hypothesis, and reviewing literature often occurs before this to understand prior knowledge on the subject.

Explanation:

The statement that the third step in the scientific method is reviewing the literature is False. The five main steps of the scientific method include: 1. Making Observations, 2. Forming a Question, 3. Forming a Hypothesis, 4. Conducting an Experiment and, 5. Analysing and Drawing Conclusions from the data. Reviewing the literature generally tends to occur before forming a hypothesis, in an aim to understand all current knowledge and previous research concerning a phenomenon or topic. It does not come after forming the hypothesis as the third step in the scientific method.

Round seeds and yellow seed color are dominant to wrinkled seeds and green seed color. What is the probability of having offspring that have wrinkled seeds and yellow seed color for the cross RRYY ´ RrYy?

Answers

Answer:

The probability of having offspring that have wrinkled seeds and yellow seed color for the cross RRYY ´ RrYy is zero

Explanation:

Given

Round see (R) is dominant to wrinkled seed (r)

While Yellow seed (Y) is dominant to green seed (y)

Now a cross is carried out between RRYY * RrYy, the following offspring are produced

RRYY * RrYy

The gametes of RRYY are RY, RY, RY, RY

The gametes of RrYy are RY, Ry, rY, ry

RY Ry rY ry

RY RRYY RRYy RrYY RrYy

Genotype Ratio

RRYY: RRYy: RrYY: RrYy

4:4:4:4

1:1:1:1

Phenotype

All are round and yellow

The probability of having offspring that have wrinkled seeds and yellow seed color for the cross RRYY ´ RrYy is zero

All offspring F1 will be dominant for Round seeds ,there will be no recessive wrinkled. Try punnett square to be sure.
