How is cytokinesis different in plants and animals?
Answer:
The main difference between plant cell and animal cell cytokinesis is the formation of new cell wall surrounding the daughter cells. Plant cells form a cell plate between the two daughter cells. In animal cells, a cleavage furrow is formed between the two daughter cells.
Explanation:

what experiments led to the discovery of dna as the hereditary material?
Answer:
In the 1920s, Frederick Griffith He was studying two different strains of a bacterium, called R (rough) strain and S (smooth) strain. He injected the two strains into mice. The S strain killed (virulent) the mice, but the R strain did not (non-virulent). Griffith also injected mice with S-strain bacteria that had been killed by heat. As expected, the killed bacteria did not harm the mice. However, when the dead S-strain bacteria were mixed with live R-strain bacteria and injected, the mice died.

What is the most likely explanation of the data shown below?
A 3 column table with 6 rows. Column 1 is labeled Year with entries 0, 1, 2, 3, 4, 5. Column 2 is labeled Dark moths with entries 50 percent, 59 percent, 68 percent, 80 percent, 95 percent, 100 percent. Column 3 is labeled Light moths with entries 50 percent 41 percent, 32 percent, 20 percent, 5 percent, 0 percent.
a.
There has been a drought in the area that is affecting all life forms.
b.
The population of natural predators of the moths has gotten smaller.
c.
The moths are living in an environment with light trees.
d.
The moths are living in an environment with dark trees.
Answer:
The correct answer is D. The moths are living in an environment with dark trees.
Explanation:
In general, the data shows the population of light moths increases over time, while the population of light moths decreases to the point it disappeared. This would likely occur if there was an environmental change that allowed dark moths to have survival and reproductive advantage over light moths. This includes if the trees are dark because in this scenario dark moths have a better chance to avoid predators and reproduce, while light moths would have a lower chance to survive because predators can find them easily and this leads to the decrease in light moths population shown in the chart.

A) There are six total atoms present
B) There are three total atoms present There are a total of two oxygen atoms
D) There are a total of four hydrogen atoms
E) There are two total atoms present hydrogen and oxygen
Examine the chemical formula shown here there are three total atoms two of which are hydrogen and one of which is oxygen and this chemical formula can be seen in the process of photosynthesis also.
What is photosynthesis?The process of photosynthesis has been defined as the process in which green plants prepare their own food in the presence of sunlight and during this process heat energy has been converted into the chemical energy and this process has been taken place in the green plant only.
Photosynthesis has the process through which plant cells use carbon dioxide & water to create oxygen & energy rich organic compounds. They do so by converting sunlight ie light energy into chemical energy. This is possible due to presence of chlorophyll in them. Animals can't do so, as they dont have chlorophyll.
Therefore,Examine the chemical formula shown here there are three total atoms two of which are hydrogen and one of which is oxygen and this chemical formula can be seen in the process of photosynthesis also.

DNA technology plays a role in medicine except identifying mutations when EXAMINING paternity. It involves the determination of the biological father.
DNA technologies refer to the genetic engineering techniques used in medicine and biotechnology for diverse purposes.
For example, DNA recombinant technologies can be used to produce insulin, which is a hormone required for the treatment of individuals suffering from diabetes.
DNA paternity tests are genetic tests whose objective is to determine nucleotide (DNA) polymorphisms and thus indicate whether a man is another individual's biological father.

Explanation:
a population undergoing natural selection would see a faster and more dramatic change in allele frequency if the starting generation contained more of the allele being selected against.
Answer: As the change in allele frequency causes the change in genome of the living organism inside few generations.
Explanation: The effect may leave the organism with the loss of some genes, while it can effect cause the loss of some of the beneficial genes inside the genome of the organism. Along with that the process can also improve the sequence of genes which are abnormal in nature.

Explain the idea of Nature vs. Nurture in your own words.
Nature vs. Nurture both influence the observed traits of an organism.
The controversy between nature and nurture have been an ongoing discourse for many years. It is believed that the traits of an organism are dependent on genes inherited from the parents. Another school of thought believes that environment alone has the sole influence over the traits of an organism.
However, most scientists today are of the opinion that the influence of nature and nurture are intertwined and they both work together to influence the traits exhibited by any organism.

Why might cyanide-producing clover produce striped leaves?
Answer:
increases its ability to resist predation because the snails that eat it die
In general, two types of white clover can be found in a variety of habitats around the world. The first has plain green leaves, while the second produces cyanide as a defensive strategy against herbivores and signals its presence with white stripes on the leaves.
What are defensive behavior?Claws, teeth, disguising, poison, imitation, and adaptations such as echolocation are all common defense mechanisms. Some are uncommon but extremely effective.
A nonhuman animal's behavior to avoid of been hurt or killed by another.
