7. Compare the results of cell division in unicellular and multicellular organisms.
The results of cell division in unicellular and multicellular organisms in unicellular organisms such as bacteria, mitosis has a type of asexual reproduction, making identical copies of a single cell. In multicellular organisms, mitosis produces more cells for growth and repair.
What is difference between unicellular and multicellular organisms?The main difference between the unicellular reproduce organisms in other hand multicellular-repairs dead or damaged cells. They both help develop and grow in the multicellular this organism has been made up of 2 or more cell they can be made up to trillion if cells, it is much more complex than the unicellular. They reproduce asexually and the cells cannot live outside the organism, they perform specialized functions an example the nerves.
Cell division in unicellular organisms is important for reproduction. Unicellular cell division used for single-celled organism. Cell division in unicellular organisms is used for the reproduction of an organism.
The importance of cell division in multicellular organisms is the development and replacement of damaged and dead cells. Cell division is important for tissue growth and cell maintenance.
Therefore, The results of cell division in unicellular and multicellular organisms in unicellular organisms such as bacteria, mitosis has a type of asexual reproduction, making identical copies of a single cell.

Why do farmers in South America get abundant crops during El Niño?
Answer:
Hundreds of years ago, South American fishermen observed that every year around December or Christmas, coastal waters of the Pacific became warmer as a current flowed from north to south. This change often meant a smaller fish catch but more rainfall inland that translated to more abundant crop harvest .

Create your own Python file in a code editor of choice and begin writing functions as defined below. Your function names, inputs, and outputs should be exactly as described. Please make sure you follow the coding guidelines from the main rubric! def dna_count(dna): This function takes in a string representing a DNA sequence and returns a list or tuple of four integers representing the number of times each nucleotide A, C, G, or T occur in the DNA string, in that order.
Answer:
In python:
def dna_count(dna):
A = dna.count('A'); C = dna.count('C')
G = dna.count('G'); T = dna.count('T')
dna_countlist = []
dna_countlist.append(A) dna_countlist.append(C)
dna_countlist.append(G) dna_countlist.append(T)
return dna_countlist
dna = input("DNA: ")
print(dna_count(dna))
Explanation:
This defines the function
def dna_count(dna):
This counts the occurrence of A and C
A = dna.count('A'); C = dna.count('C')
This counts the occurrence of G and T
G = dna.count('G'); T = dna.count('T')
This creates an empty list
dna_countlist = []
This appends the occurrence of A and C to the empty list
dna_countlist.append(A) dna_countlist.append(C)
This appends the occurrence of G and T to the list
dna_countlist.append(G) dna_countlist.append(T)
This returns the list
return dna_countlist
The main begins here
This prompts the user for the DNA string
dna = input("DNA: ")
This calls the dna_count function and also prints the returned list
print(dna_count(dna))

Answer:
Even though you did not eat the grains and legumes together, your body can synthesize new protein over the course of the day. But if you ate your toast with peanut butter, it would be a complete protein, meaning all essential amino acids are delivered within one meal.

Which of the following statements is not true of the circulatory system and its transport of nutrients?
a. Water-soluble nutrients leave the small Intestine via lymph.
b. Nutrients that leave the small intestine via blood are delivered first to the liver.
c. Lymph empties into the blood just before the blood reaches the heart.
d. Lymph is formed from fluid that Is forced out of capillaries by blood pressure.
Answer: b. Nutrients that leave the small intestine via blood are delivered first to the liver.
Explanation:
Lymph is a clear fluid that leeks out from the interstitial spaces of the cells and this comprises of electrolytes, blood proteins, and antibodies. It is pushed towards the heart from the lymphatic vessels. The nutrients from the small intestine are drained into the bloodstream and they are circulated to all parts of the body and not directly destined towards the liver.

A doctoral student in biology, Esther Mensah, is reviewing primary literature over RNAi interference as part of her literary research for her proposal on decreasing the amount of abnormal white blood cell growth associated with acute myeloid leukemia (AML) using a murine (mouse) model. She is being provided with 10 AML mice courtesy of her mentor. Can you help her out with her proposal
Answer:
She might study the function of putative oncogenes and/or tumor suppressor genes in AML mice by transfecting small interfering RNAs (siRNAs) which are able to suppress the expression of genes of interest through the RNA interference (RNAi) pathway
Explanations:
The RNA interference (RNAi) pathway is a naturally occurring mechanism which is used in molecular biology laboratories to inhibit the expression of target genes. The RNAi technique consists of delivering small interfering double-stranded RNAs (siRNAs, 18-30 nucleotides in length) into the cells in order to inhibit the translation of genes and/or trigger mRNA degradation, thereby suppressing target gene expression. These siRNAs are specifically designed to bind by complementarity to transcripts of target genes (i.e., mRNAs). In this case, the RNAi pathway can be used to study the function of genes involved in AML pathways (e.g., apoptosis, cell proliferation, etc).

Do you agree with the article’s assessment that bedbugs are parasites? Explain your reasoning using what you’ve learned about parasitic relationships.
article:
When bed bugs suddenly made a comeback in recent years, biologists were just as surprised as everyone else. Few had studied the bugs because there seemed no need to do so. But as bed bugs became ever harder to kill, scientists began probing hard to find their weaknesses.
To do that, they invited some of the bugs to stay in the lab. There, researchers could observe them closely. But to be good hosts, the scientists had to keep their bugs healthy and well-fed. And that has required learning how to deliver these critters the blood on which they thrive.
Answer:
Yes, bedbugs are parasites. They need a host—humans—to survive. However, they don’t benefit humans at all. In fact, they cause harm. As they feed off humans, they leave behind red, itchy welts on the skin.

A phycologist is interested in determining the proportion of algae samples from a local rivulet that belonged to a particular phylum. A random sample of 50 alga was obtained and each alga was categorized as either being cyanobacteria or not. It was found that 38 were, in fact, cyanobacteria. The proportion 'p-hat' that were cyanobacteria is
Answer:
The proportion 'p-hat' that were cyanobacteria is 0.76
Explanation:
The proportion of cyanobacteria is the relationship between the whole sample and the actual quantity of cyanobacteria found in the sample, that were not other algae. In general, proportions are written as fractions. The numerator is the number of cyanobacteria in the sample, while the denominator is the total number of organisms in the sample.
So, in the exposed example we know that
The sample was composed of 50 algaeThere were two categories for the sample: algae that were cyanobacteria, and algae that were not cyanobacteriaAlgae that were cyanobacteria = 38 Algae that were not cyanobacteria = 12If we want to study the relationship between the sample and cyanobacteria and express it as a proportion, then we need to divide the number of cyanobacteria by the number of algae in the sample. This is
38/50 ----> Fraction expression of the relationship between cyanobacteria
and the sample
0.76 ----> Proportion of cyanobacteria in the whole sample.
