A component of the cell that collects freshly generated proteins and other materials from the endoplasmic reticulum wraps them, and transports them to other areas of the cell is called the Golgi apparatus. The correct option is B.
What is the Golgi apparatus?Golgi apparatus is an organ of the eukaryotic cells. It is an irregular-shaped organ. It was discovered by Camillo Golgi. That's why its name is Golgi apparatus.
There are many functions of this organ. It helps in the packaging of proteins and lipids molecules. These proteins are then transported to other parts of the cell.

This problem leads you through the derivation of a corrected equation for RF in yeast tetrad analysis that takes into account double crossover (DCO) meioses. A yeast strain that cannot grow in the absence of the amino acid histidine (his−) is mated with a yeast strain that cannot grow in the absence of the amino acid lysine (lys−). Among the 400 unordered tetrads resulting from this mating, 233 were PD, 11 were NPD, and 156 were T.
a. What types of spores are in the PD, NPD, and T tetrads?
b. Are the his and lys genes linked? How do you know?
c. Using the simple equation RF = 100 × [NPD +(1/2)T]/total tetrads, calculate the distance in mapunits between the his and lys genes.
d. If you think about all the kinds of meiotic eventsthat could occur (refer to Fig. 5.24), you can see that the calculation you did in part (c) may substantially underestimate RF. What kinds of meioses (NCO, SCO, or DCO) generated each of the tetrad types in this cross?
e. What incorrect assumptions does the simple RFequation you used in part (c) make about themeiotic events producing each type of tetrad? Whencould these assumptions nevertheless be correct?
f. Use your answers to part (d) to determine thenumber of NCO, SCO, and DCO meioses thatgenerated the 400 tetrads.
g. Use your answers to part (f) to write a generalequation that relates the number of DCO meiosesto the number of the various tetrad types. Thenwrite another general equation that computes thenumber of SCO meioses as a function of the number of the various tetrad types.
h. Based on your answer to part (f), calculate theaverage number of crossovers per meiosis (m)between his and lys.
i. Use your answer to (h) to write an equation for min terms of NCO, SCO, and DCO meioses.
j. What is the relationship between RF and m?
k. Use your answer to part (j) to write a corrected equation for RF in terms of SCO, DCO, and NCO meioses. l. Using your answer to part (g), rewrite the corrected RF equation from part (k) in terms of the numbersof the various tetrad types.
m. The equation you just wrote in part (l) is a corrected equation for RF that takes into account doublecrossovers that would otherwise have been missed. Use this improved formula to calculate a moreaccurate distance between the his and lys genes than the one you calculated in part (c).

Populations are greater in fertile areas that are close to freshwater sources, which is why more people live near oceans.
Populations are greater in fertile areas that are close to freshwater sources, which is why more people live near mountains.
Populations are greater in fertile areas that are close to freshwater sources, which is why more people live near rivers.
Answer:
D. Populations are greater in fertile areas that are close to freshwater sources, which is why more people live near rivers.
Explanation:
Population is greatly depend on the availability of water. Those areas are densely populated areas where water is present in sufficient quantity as compared to those areas have low population density where water is in low amount. The main reason is that water plays a vital role in our daily life which is used almost in every aspects of life. We can see that deserts have less population due to less water availability and areas attached to the rivers are densely populated due to more water availability.

Which two atoms form a covalent bond?
A. A sodium and chlorine atom
B. Two oxygen atoms

How does the anaphase stage differ in the two phases of meiosis? A. Anaphase I separates sister chromatids and anaphase II separates homologous chromosomes into daughter cells. B. Anaphase I has homologous chromosomes attached to spindle fibres and anaphase II involves separation of these homologous chromosomes. C. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
Answer:
The answer is Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. So, in meiosis, there are two anaphases - the anaphase I in meiosis I and the anaphase II in meiosis II.
In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicate, which are present as pairs of sister chromatids. In anaphase of meiosis II, since the cell is haploid, there are 23 chromosomes in duplicate, which are present as sister chromatids.

Explain how this experiment disproves the theory of spontaneous generation.
Answer:
The theory of spontaneous generation suggested that the living organisms can come from inanimate objects, however, it is an obsolete theory that is disproved by many experiments. The very first experiment that disapproved it was the experiment by Francesco Redi in 1668.
He demonstrated that maggots come from the eggs of flies instead of rotting meat. He placed raw meat inside of every jar. Half the jars he left open and the other half, he covered with mesh. In open jars, he found maggots after some time but covered jars have no maggots. That proved that the maggots come from eggs of flies rather than rotten meat.
The presence of flies on the meat is responsible for the production of maggots in meat.
This experiment disproves the theory of spontaneous generation because maggots are produced from the flies not the rotten meat. According to spontaneous generation, living organisms are formed or develop from nonliving matter.
So by performing this experiment we can see that maggots are formed when the flies feed on the rotten meat otherwise no maggots are present if the flies are not present there so that's why we can conclude that this experiment rejects the theory of spontaneous generation.

How are viruses different from Bacteriophages?
Answer: It's different because it is a bacteria eater.
Explanation: A bacteriophage is a type of virus that infects bacteria. In fact, the word "bacteriophage" literally means "bacteria eater," because bacteriophages destroy their host cells. All bacteriophages are composed of a nucleic acid molecule that is surrounded by a protein structure.

Which graph shows the presence of nitrogen-fixing bacteria in the soil
Answer:
2
Explanation:
The graph that shows the presence of nitrogen fixing bacteria in the soil would be graph 2.
Nitrogen fixing bacteria are bacteria that are capable of converting atmospheric nitrogen into plant-usable nitrogen in the soil. The conversion is done in two stages;
1. First, atmospheric nitrogen is converted into ammonia.
2. Ammonium is converted into usable nitrate
Hence, the correct graph is the one in which the amount of atmospheric nitrogen decreases with a corresponding increase in the amount of ammonia. This would indicate the conversion of nitrogen into ammonia which is the first step in nitrogen fixation by nitrogen-fixing bacteria.
Graph 2 represents the presence of nitrogen-fixing bacteria in the soil.
This is because in this graph the concentration of atmospheric nitrogen (N2) is lower and the concentration of ammonium (NH4) is higher. The nitrogen-fixing bacteria converts or fixes atmospheric nitrogen that can't be absorbed by the plants into ammonium or nitrates which can be absorbed by the plants and make necessary amino acids for the body so we can conclude that graph 2 indicates the presence of nitrogen-fixing bacteria in the soil.

If one strand of DNA double helix has the following nucleotide sequence ATCGGTCAAGCTAGG what would the dna complementary stand read
Answer:
TAGCCAGTTCGATCC
Explanation:
In DNA, there are 4 different nucleotide bases. Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).
A (adenine) always pairs with T(thymine) and C(cytosine) always pairs with G (guanine).
If we have the strand:
ATCGGTCAAGCTAGG
We have to pair A with T, and C with G. Therefore, the complementary strand of DNA will be:
TAGCCAGTTCGATCC
