What happens during interphase that allows the two resulting cells to be the same as the
original cell?
Answer:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. ... Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.

Why are leaves of water lily coated with wax on the upper surface?
Answer:
The wax creates an outer layer of zero friction surface helping the water lily leaves float on the water surface, the wax also creates a shiny coating that reflects and lowers the temperature of the water and also prevents water loss by evaporation and helps in prevention of other plant diseases.

Which contributes to the movement of air masses
Answer:
The Movement of Air Masses: transporting warm air northward and colder air southward. Counterclockwise winds associated with cyclones transport heat and moisture from lower to higher latitudes and play a significant role in the movement of air masses. A warm front marks the leading edge of this warm, moist air mass.

how does blood volume affect blood pressure
Answer:
Changes in blood volume affect arterial pressure by changing cardiac output. An increase in blood volume increases central venous pressure. This increases right atrial pressure, right ventricular end-diastolic pressure and volume.

Which of the following statements regarding selenium/selenoproteins is incorrect?
a. They are proven protection against colon cancer.
b. The amount of selenium in foods depends upon the soil where the plants were grown and animals grazed.
c. Selenium functions as an antioxidant.
d. Selenium plays an important role in the regulation of thyroid hormones.
Answer:
The correct answer is: A. They are proven protection against colon cancer.
Explanation:
Selenium is a mineral that can be incorporated into our bodies in small amounts when we consume certain foods, such as whole grain and dairy products. The amount of selenium in these products depends on the soil where the plants and animals were.
Selenium plays an important role as an antioxidant, which can lower the risk of developing several types of cancer. However, this doesn't mean that its consumption can prevent colon cancer, and the studies that had been done to prove its effectivity in these regards have been inconclusive.
Besides functioning as an antioxidant, selenium also is very important for the regulation of the thyroid hormones, which play an important part in metabolism.
The protein that contains selenocysteine amino acid remnants is called selenoproteins. They are found in the endoplasmic reticulum of the cells.
The incorrect statement is:
Option a. They are proven protection against colon cancer.
The statement can be explained as:
Selenium is a mineral that gets incorporated into our body through foods, dairy and whole grains. The amount of selenium depends on its amount and presence in the soil.Selenoproteins are good antioxidants that can lower the risks of cancers. But its consumption does not provide complete protection against cancers.It also regulates the thyroid hormone and plays a vital role in the regulation of metabolism.Thus, they have not proven medication for colon cancer.

Why does the moon have a greater influence on Earth's Tides than the sun does
Answer:
Because ocean tides are the effect of ocean water responding to a gravitational gradient, the moon plays a larger role in creating tides than does the sun. But the sun's gravitational gradient across the earth is significant and it does contribute to tides as well.

Fungi help catabolism of complex organic matter into simple available inorganic forms. In other words they breakdown organic matter to obtain energy. This process of decomposition requires aerobic ambient and moisture therefore they are mostly found in moist habitats rich in detritus.
Explanation:
Fertilizer runoff causes an increase in the dissolved nutrients of the ecosystem shown in the food web below. This causes the number of phytoplankton to double.
How will this most likely affect the other species in this ecosystem?
A.
The shrimp population will increase which will cause an increase in the squid population.
B.
The shrimp population will decrease which will cause an increase in the squid population.
C.
The shrimp population will decrease which will cause an increase in the sperm whale population.
D.
The shrimp population will increase which will cause a decrease in the sperm whale population.
Answer:
I believe the answer is A because if shrimp eat phytoplankton, and squid eat shrimp this should work. I am not positive but I hope this helps.
Some bacteria live in the roots of plants like soybeans and peas.
Bacteria growing on plant roots.
What is the role of these bacteria in the nitrogen cycle?
Answer:
Nitrogen is the most commonly limiting nutrient in plants. Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation. Rhizobia bacteria convert nitrogen gas (N2) to ammonia (NH3) in a process called nitrogen fixation.
Answer:
to convert free nitrogen into usable nitrogen

A DNA molecule is made up of building blocks known as nucleotides. Each nucleotide consists of deoxyribose, a phosphate group, and one of the chemical bases. The nucleotides join together to form a
, which form the backbone of a DNA strand.
Answer:
polynucleotide
Explanation:
according to edmentum notes, "The nucleotides join together to form a polynucleotide. Polynucleotides form the backbone of a DNA strand.'
Nucleotides are the building units of the DNA or RNA molecule. DNA is composed of deoxyribose, a phosphate group, and one of the chemical bases that make up each nucleotide.
What is a nucleotide?It is a monomer of DNA or RNA. It is composed of a sugar (deoxyribose in DNA ribose in RNA), a phosphate group, and one of the chemical bases that make up each nucleotide.

DPIP was used in the photosynthesis lab to measure the
-Light dependent reactions
-Production of O2
-Light Independent reaction (a.k.a. Calvin cycle)
-Production of CO2
Answer:
Light dependent reactions
Explanation:
DPIP stands for Dichlorophenolindophenol. It is a chemical compound that is used as a redox dye.
DCPIP is blue when it is oxidized DCPIP is colorless when it is reduced.
DCPIP measures the rate of photosynthesis. The redox dye is decolorized by chemical reduction when it is exposed to light in the process of photosynthesis.
DPIP was used in the photosynthesis lab to measure the light dependent reactions.

What are the five main functions of nematodes in soil?
Answer:
Nematodes are the bacterial feeders, fungal-feeders, plant parasites, predators, and omnivores.
Explanation:
hope this helps :)
Answer:
Nematodes play an important role in nutrient cycling. In particular, they play a key role in the nitrogen cycle. Nematodes take in nitrogen and excrete it in a form that plants and bacteria can use.
Nematodes graze on bacteria, plants, and other soil organisms. In ecosystems, nematodes play a major role in regulating the populations of their prey organisms.
Nematodes carry fungi and bacteria in and on their bodies. As nematodes move through the ecosystem, they disperse the bacteria and fungi.
Nematodes are a part of food chains and food webs. They are an important food source in many ecosystems.
Nematodes impact the health of other organisms. Some help prevent, or suppress, disease by eating other disease-causing organisms. Other nematodes cause disease in plants and animals.

homozygous for both characters? Give all genotypes and phenotypes of these homozygotes.
Answer:
Explanation:
Short hair (S) is dominant over long hair (s), and black coat color (B) is dominant over albino (b).
A female of a true breeding line with a black coat and long hair is mated with a short haired albino male (also from a true breeding line)
parents genotype BBss x SSbb
gametes Bs x Sb
F1 generation geenotype BbSs
Phenotype- They are all with black coat and short hair
Mating of F1 BbSs x BbSs
Percentage of offspring homozygous for both characters:
Bb x Bb Ss x Ss
BB Bb Bb bb SS Ss Ss ss
1/4 1/4 1/4 1/4
1/4*1/4 = 1/16 = 0.0625 = 6% for each homozygous characters (BBSS-6% and bbss-6%)
The genotypes of the homozygotes are BBSS and bbss
The phenotype of BBSS is black coat with long hair
The phenotype of bbss is an albino with short hair
