Which process is shown in the plant cell below?
A= cell growth
B= cell reproduction
C= metamorphosis
D= photosynthesis
Answers
The given process shown in the image is cell reproduction. Cell reproduction takes place by mitosis and meiosis.
What is cell reproduction?Mitosis and meiosis are the two distinct processes of cell division. When people talk about "cell division," they typically mean mitosis, which is the process of creating new cells for the body. The cell division process known as meiosis is what produces egg and sperm cells.
A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis.
Meiosis, the second sort of cell division, makes sure that each generation of people has the same number of chromosomes.
Therefore, The given process shown in the image is cell reproduction. Cell reproduction takes place by mitosis and meiosis.

Businesses can perform and fund research studies, which potentially creates bias.
Scientific journals have a long history of publishing questionable research.
Government funding of research studies has the potential to create bias.
Poor research could potentially impact the health and welfare of the public.
Answers
Answer:
Poor research could potentially impact the health and welfare of the public.
Explanation:
Scientific studies are generally believed to be based on thorough research. This implies that members of the public always trust scientific publications and rely on same as a source of accurate and trustworthy information.
Science, being empirical in nature is believed to eliminate bias in its research and reportage of studies. Scientific research publications is often a source of information for field practitioners in diverse disciplines as well as the general public.
Poor research will mislead a large section of the public, both professionals in that field as well as laymen. This poor research could potentially impact the health and well being of members of the public negatively because they may be led to believe false information which can be disastrous. This is the reason why ethical guidelines are needed for the way scientific information is communicated.
In an experimental study of the effect of copper deficiency on coat color in bicolored juvenile rats, the independent variable is?
Answers
Answer:
amount of copper
Explanation:
The independent variable would be the amount of copper fed into the experimental rats.
An independent variable during an experiment is a variable whose value is not dependent on any other variable being measured in the experiment.
The value of an independent variable is not changed by any other variable in an experiment. In actual fact, the effect of the independent variable is being tested on other variables (dependent variables) in the experiment.
Hence, in an experimental study of the effect of copper deficiency on coat color in rats, the amount of copper fed into the system of the rats will be varied and the effects of this variation on the coat color of the rats would be observed by measuring relevant variables. Therefore, the amount of copper is the independent variable.

Which graph shows the presence of nitrogen-fixing bacteria in the soil
Answers
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.

what is the composition of gastric juice and their functions?
Answers
Answer:
Mostly HCl, Pepsin, Lipase, Water, and other Electrolytes
Explanation:
The gastric mucosa secretes 1.2 to 1.5 litres of gastric juice per day. Gastric juice renders food particles soluble, initiates digestion (particularly of proteins), and converts the gastric contents to a semiliquid mass called chyme, thus preparing it for further digestion in the small intestine. Gastric juice is a variable mixture of water, hydrochloric acid, electrolytes (sodium, potassium, calcium, phosphate, sulfate, and bicarbonate), and organic substances (mucus, pepsins, and protein). This juice is highly acidic because of its hydrochloric acid content, and it is rich in enzymes. As noted above, the stomach walls are protected from digestive juices by the membrane on the surface of the epithelial cells bordering the lumen of the stomach; this membrane is rich in lipoproteins, which are resistant to attack by acid. The gastric juice of some mammals (e.g., calves) contains the enzyme rennin, which clumps milk proteins and thus takes them out of solution and makes them more susceptible to the action of a proteolytic enzyme.
Answers:
It is a unique combination of hydrochloric acid (HCl), lipase, and pepsin. It is found in all vertebrates.
Main function is to inactivate microorganisms.

2. Assume that crossing over does not occur in the region of each chromosome that is associated with the centromere. You have 46 centromeric regions in each cell, 23 that are copies of the DNA in your mother’s egg and 23 that are copies of the DNA father’s sperm. Show your work for A,B,C a. For any given gamete, what is the probability that all the centromeric regions (chromosomes) will be copies of the same ones that you received from your mother? b. It has been estimated that the average person is heterozygous for at least 2,000 protein forming genes. How many different kinds of gametes is it theoretically possible for each person to produce? c. Considering the maternal and paternal origin of the centromeric regions alone, how many different kinds of gametes can you produce?
Answers
Answer:
See below
Explanation:
A. centromeric regions from mother in one cell: 23
total number of centromeric regions in one cell: 46
for every centromeric region that is inherited by the gamete, there is a 0.5 probability that it is from the mother. Hence, if all are from the mother:
0.5 ^ 23 = 1.19 x 10^(-7)
B. Heterozygous for 2000 genes means 4000 possible alleles.
2 ^ 4000 = 1.3 x 10^(1204)
C. 2 ^ 46 = 7.03 x 10^(13)

in order to survive in its environment a single celled organism uses a contractile vacuole to remove excess water that diffuses into its cell. Another species a hydra also excretes excess water. Both processes involve the use of energy. Based on this information, state whether these two organisms live in fresh water or salt water support your answer
Answers
Answer:
They would live in salt water.
Explanation:
Salt water is a hypertonic solution where water needs to move outside of the cell because there is too much solute outside. Because the 2 organisms are removing excess water, it shows that they are living in salt water where water flows outside instead of inside the cell.
Based on the available information, these two organisms would:
Live in salt waterAccording to the given question, we can see that there is a need for survival which makes a single celled organism to make use of the vacuole to remove the excess water which it diffuses into its cell.
As a result of this, we can see that another specie, a hydra also excretes excess water which involves the use of energy.
Therefore, the conclusion we can reach about them is that they are living in salt water because it is a hyper tonic solution which allows water to move freely outside the cell because of the excess solute outside the cell wall.
