Explanation:
Sperm cells are about to be made from a cell with 66 chromosomes. How many chromosomes will the sperm cells have?
Answer:
33
Explanation:
Gametes (sperm or egg) have half the chromosome of a diploid cell. That's why they are haploid cells.
If chromosomes come from a cell with 66 chromosomes, sperm will have 66/2 = 33.
That's why us humans have 46 chromosomes, but our egg or sperm has only 46/2 = 23 chromosomes.
Answer:
33 chromosomes
Explanation:
The cell undergoes reduction-division to produce 2 daughter cells with equal number of chromosomes. Hence, the sperm cells will have 33 chromosomes.

The food web below represents the organisms that make up a freshwater ecosystem. Suppose that a chemical released into the ecosystem causes a large decrease in the number of aquatic plants. Which group or groups of organisms will be negatively impacted by this change?
Answer:
All groups.
Explanation:
if small fish, insects, ducks, snails, etc don't have food they will decrease in population and starve the organisms above them in the feed web, like a domino effect.
A snow-covered mountain has a higher albedo than a dark-colored corn field. Therefore, it will reflect solar energy _____ than the field. (lower, more, less).
A snow-covered mountain has a higher albedo than a dark-colored corn field. Therefore, it will reflect solar energy more than the field.
Does snow have a high or low albedo?Dark surfaces absorb the rays from the sun (low albedo). Ice- and snow-covered areas have high albedo, and the ice-covered Arctic reflects solar radiation which otherwise would be absorbed by the oceans and cause the Earth's surface to heat up.
Why does snow have a high albedo?Freshly fallen snow reflects incoming solar radiation very well and therefore has a high albedo. New snow typically has an albedo of 0.96 to 0.98 in the visible and near-UV range (Grenfell et al., 1994), and 0.8 averaged over the entire wavelength spectrum.

The motion of molecules and the transfer of energy decreases with increase in volume of the solution.
What is effect of volume in motion of particles?The volume of a solution is inversely proportional to the motion of the molecules of a substance.
An increase in volume results in a decrease in the motion of particles due to a decrease in the frequency of particles and thus, less energy is transferred.
Therefore, the motion of molecules and the transfer of energy decreases with increase in volume of the solution.

how do mutations contribute to genetic variation
Answer: Genetic Change
Explanation:
Mutations contribute to genetic variation by causing new traits to emerge. Mutations happen when there is a change in the DNA of a creature developing in utero. These random changes in creatures are common, although most mutations end up being lethal or inhibiting to the organism. In rare cases, this mutation can prove benificial or helpful, and if the organism reproduces and the trait is passed along, it could become a new branch of genetic variation within the species.
What adverse effects does covering the land with concrete and asphalt create?
Answer:
They Deplete resourcesThey Pollute waterThey Generate Harmful Atmospheric EmissionsExplanation:
Motor vehicle traffic and its accompanying pollution have been a major environmental concern for decades The materials used, primarily asphalt and concrete, negatively impact the environment in three ways. In built areas with extensive impervious surfaces, water can't soak naturally into the earth instead it rushes across the landscape, carrying pollutants and biological contaminants into our waterways, poisoning fish, wildlife, and us.

Food webs and the ecosystems that support them look different in different parts of the world depending on their habitat conditions.
What do you mean by Ecosystem?An Ecosystem may be defined as a place or area where members of different species or communities live and interact with one other for the purpose of food, shelter, space, or other resources.
Food webs constantly supply energy from one level of organisms to other levels of organisms randomly. It basically depends on the type of habitation present in particular conditions.
The place of producers remains the same for food webs and food chains. The food chain transferred energy in a defined way, rather than food webs.
Therefore, food webs and the ecosystems that support them look different in different parts of the world depending on their habitat conditions.

Most of the products of fat digestion are absorbed by Lymphatic vessels.
Where fat is digested in the body?Fat is digested in the small intestine along with the majority of nutrients.
The fatty acids that are composed of long chains synthesize a large structure of lipoprotein which is known as chylomicron which is responsible for the absorption and transport of fats through the lymphatic system.
Therefore, most of the products of fat digestion are absorbed by Lymphatic vessels.

How does a diploid organism restore its number of chromosomes if meiosis produces haploid cells?
The condition is called diploidy. During meiosis the cell produces gametes, or germ cells, each containing half the normal or somatic number of chromosomes. This condition is called haploidy.
How does meiosis reduce the number of chromosomes from diploid to haploid?The parent cell undergoes one round of DNA replication followed by two Different cycles of nuclear division.
The method results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Thus,The condition is called diploidy. During meiosis the cell produces gametes, or germ cells, each containing half the normal or somatic number of chromosomes.

Describe what happens during the phases of mitosis
Answer:
Mitosis is the phase where the cell splits its chromosomes equally among two daughter cells, and branches off into more cells.
In mitosis, there is the prophase, prometaphase, metaphase, anaphase, and telophase.
The prophase is where the nuclear envelope breaks down and chromosomes attach to spindle fibers. The metaphase is where chromosomes line up at the equator. In the anaphase, the cells move to opposite poles to split. Last but not least, the telophase. In this final phase, the two nuclei split into new cells.
