Answer:
RBCs contain hemoglobin (pronounced: HEE-muh-glow-bin), a protein that carries oxygen. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs. As the blood travels through the body, the hemoglobin releases oxygen to the different body parts.

Which of the following statements explains why the process of mitosis is essential to life?
A.Mitosis is the process by which the nucleus of the cell divides and is responsible for limiting genetic variation.
B.Mitosis is the process by which the nucleus of the cell divides and is responsible for increasing genetic variation.
C.Mitosis is the process by which the parent cell divides into two separate cells and is responsible for limiting genetic variation.
D.Mitosis is the process by which the parent cell divides into two separate cells and is responsible for increasing genetic variation.
Answer:
its C option that mitosis is a process by which a parent cell divides into two seperate cells and is responsible for limiting genetic variation.
Explanation:
The somatic cell division resulting in two daughter cells is called mitosis. The parent cell divides to form cells and limits genetic variations. Thus, option C is correct.
What is mitosis?Mitosis has been defined as cell division that occurs in all somatic cells and results in genetically identical daughter cells that have been known to have the same ploidy as the parent cell.
The nucleus and the other organelles of the cell divide and undergoes division to form two new cells with an equivalent amount of the material. They separate the cells equal genetic material.
They limit the genetic variation as they do not undergo recombination and crossing over, unlike the meiotic division. They are important for the growth, repair, and continuity of life.
Therefore, option C. miotic division results in two daughter cells.

The Gulf of Mexico dead zone that forms each summer at the mouth of the Mississippi River is caused largely by the input of agricultural fertilizers that stimulate phytoplankton blooms, which die, and are subsequently consumed through bacterial decomposition. Decomposition consumes oxygen, leading to very low dissolved oxygen levels and subsequent death or emigration (i.e. leaving the area) of fish and other marine life. Many scientists advocate creating wetlands (as well as restoring them) as a strategy to reduce the severity and extent of the dead zone. The idea is that the plants in the wetlands will remove these nutrients from the water (during growth) and prevent their washing into the river and the Gulf of Mexico. Would the use of created wetlands be considered biotechnology
Answer:
Yes; the use of created wetlands would be considered biotechnology.
Explanation:
The created wetlands will employ the use of scientific tools and techniques, which will largely modify the plants, animals, and microorganisms in the Gulf of Mexico's dead zone. Generally, it has been established that biotechnology allows farmers to grow more food with environmentally sustainable farming techniques, which also improve soil conservation.
Answer:
Yes, the use of created wetlands would be considered biotechnology.
Explanation:
Biotechnology uses biological systems and living organisms to develop and create different products. The new wetland that they create will be made with the usage of scientific tools and techniques in order to replicate an already existing biological system. It will have very modified plants, animals and other organisms in the Gulf of Mexico's dead zone.

A. The gene pool gets PLEASEEEE HELP ASAP smaller over time.
O B. The number of phenotypes increases.
C. The allele frequency does not change.
O D. The alleles are distributed evenly.
SUBMIT
Answer:
C. Allele frequency does not change
the Hardy-Weinberg equilibrium occurs when allele frquencies stay the same across many generations. For example, there are no more mutations taking place.
A population is in Hardy-Weinberg equilibrium has its allele frequency remaining unchanged as there are no external factors affecting the population.
What is the Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium refers to an equilibrium found in a population of organisms in which the allele frequencies in the population is constant.
In a population in Hardy-Weinberg equilibrium, the sum of the allele frequencies of the organisms is equal to 1.
Therefore, when a population is in Hardy-Weinberg equilibrium, the allele frequency does not change.

Figure 4.4 shows three wave crests moving to the right. When the crest of wave A passed point P, a watch reads 0.00 seconds. When the crest of wave B passed point P, a watch reads 10.00 seconds.
What is the period of the wave?
Answer:
period = 10.00 s, frequency = 0.1 Hz
Explanation:
The period of the wave T, is the time it takes the wave to move between two successive crests. Since wave A passes point P at 0.00 seconds and wave B passes point P at 10.00 seconds, it completes a cycle of the wave and the period, T is 10.00s - 0.00 s = 10.00 s.
So, the period of the wave is T = 10.00 s
The frequency, f = 1/T = 1/10.00 s = 0.1 Hz

Positive hydrogen ions form during intermediate stages of photosynthesia. What is the composition of these ions?
A. a proton and two electrons
B. a single proton
C. two protons and an electron
D. a proton and an electron
Answer:
The correct option is B. a single proton.
Explanation:
During intermediate stages of photosynthesis, water molecules are broken down releasing oxygen (O₂), hydrogen ions (H⁺) and electrons. Hydrogen ions and electrons are used in subsequent stages.
The produced hydrogen ions (H⁺) are composed by only a proton, without electrons. These positive ions are formed when a neutral hydrogen atom (H, with 1 proton and 1 electron) loses its single electron.
Therefore, the correct option is B. a single proton.

if a cow and a calf eat a bale and a half everyday and a half. how many bales will they eat in one week?
Answer:
10 and a half
Explanation:
There are 10 bales and half will a cow and a calf will eat in one week.
What is a Bale?A bale may be defined as a large quantity of grass or its derived product that is pressed tightly together and tied up in the form of circular structure. In other words, it is significantly conveyed as a bundle of grass.
According to the question, the amount or quantity of bale a cow and a calf eat in a day = 1 bale and a half = 1.5 bale.
The Number of days in a week = 7.
The number of bales will they eat in one week = 7 × 1.5 = 10.5 bales.
It is also written as 10 bales and a half.
Therefore, there are 10 bales and half will a cow and a calf will eat in one week.

Answer: The question is incomplete as the options are not given, here are the options gotten from another websites.
A. Most Probable Number method (MPN)
B. Microscopic counts
C. Turbidimetric methods
D. Standard Plate Counts (SPC)

Which characteristic is observed in both prokaryotic and eukaryotic cells?
A presence of cytoplasm
B reproduction by binary fission
C presence of membrane-bound organelles
D reproduction requires a host
Answer:
The correct answer is - option A. presence of cytoplasm
Explanation:
Prokaryotic and Eukaryotic cells both have some similarities and some differences. The differences between these cells make them specific and help in classified the organism as eukaryotic and prokaryotic organisms. The prokaryotic cell requires a host to reproduce itself or reproduces by the means of binary fission whereas the eukaryotic cells reproduce in various ways and did not require a host.
In eukaryotic cells there are double membrane-bound organelles are found whereas prokaryotic cells lack such organelles. The cytoplasm is present in both the cell eukaryotic and prokaryotic cells.

What would happen if you attempted to carry out the desaturation of stearoyl-CoA under anaerobic conditions
Answer:
The effect of Fx on hepatic stearoyl-coenzyme A desaturase-1 (SCD1), a rate-limiting enzyme that catalyzes the biosynthesis of monounsaturated fatty acids from saturated fatty acids, has been studied in obese mouse models of hyperleptinemia (KK-A(y)) and leptin-deficiency (ob/ob). In KK-A(y) mice fed a diet containing 0.2% Fx for 2 weeks, SCD1 mRNA and protein expression were reduced in the liver with a concomitant decrease in serum leptin levels. In contrast, the suppressive effects of Fx on hepatic SCD1 and body weight gain were not observed in leptin-deficient ob/ob mice. These findings support the hypothesis that Fx down-regulates SCD1 expression and alters fatty acid composition of the liver through regulation of leptin signaling (Beppu et al., 2013).
