what are the four final cell types produced by oogenesis in the female
Answer:
Oogenesis in the female is the process that produces fertile eggs, ready for fertilisation by the male sperm. Each egg has only one of each of the 23 human chromosomes - normal body cells have a pair of each, having 46 chromosomes in total.
To produce egg cells, the process of oogenesis takes place in the female ovary. Progenitor cells divide through a cell division process called meoisis, which is also known as a reduction division.
Instead of one cell splitting into two identical cells, four cells are produced which have half the normal number of chromosomes - they are described as being haploid.
The four cells are all genetically different because the process of meiosis involves cross overs of the chromosomes during division, so mixing up the genes inherited from the woman's mother and the woman's father. This variation produces fitter offspring as it widens the genetic variation that is possible.Explanation:

Find the remainder when p(x) = –2x5 + x4 + 5x3 + 4x + 1 is divided by (x - 2).
The remainder when p(x) = -2x⁵+x⁴+5x³+4x+1 is divided by (x-2) is 1.
To solve the question above, we make use of the remainder theorem.
Remainder Theorem: It states that if a function F(x) is divided by (x-a), the remainder is F(a).
From the question,
Given:
Dividend ⇒ p(x) = -2x⁵+x⁴+5x³+4x+1Divisor ⇒ (x-2)in view of the above and applying the Remainder theorem, The remainder will be p(2)
p(2) = -2(2⁵)+2⁴+5(2³)+4(2)+1p(2) = -64+16+40+8+1p(2) = 1hence the remainder when p(x) = -2x⁵+x⁴+5x³+4x+1 is divided by (x-2) is 1

Explanation:
if you visit the beach on a hot summer day you will probably feel a Sea Breeze coming off the water onto the land. Which of the following causes this sea breeze?
A. The water is warmer than the land during the day.
B. Hurricanes that form in the oceans blow air into the shore.
C. During the day,solar radiation warms the land faster than the water.
D. Earth is tilted toward the Sun, causing air to move inland from the water
If I am correct, the answer is supposed to be C due to on hotter portions of the day, land warms much faster than the water. This causes cooler air to rise from the oceans and the wind currents then push the air towards the land.
in the ecosystem energy budget, primary productivity is like _____.
Answer: Income
Explanation:
In the ecosystem energy budget, primary productivity is like income. This is because primary production is the way in which energy enters an ecosystem.
I hope this helps :}
In the ecosystem energy budget, primary productivity is like income. Therefore, the correct option is B.
What is primary productivity?Primary productivity is the rate at which organic matter is produced by photosynthesis in an ecosystem. It represents the energy that enters the ecosystem from the sun and is available for consumption by other organisms. Therefore, like income, primary productivity is a source of energy that is available to be “spent” by organisms in the ecosystem.
Option A, debt, is not an appropriate analogy for primary productivity, as it implies a negative balance. Option C, the interest rate, is also not an appropriate analogy, as it does not represent a source of energy but rather a factor that affects the rate of exchange of energy. Option D, spending, is a closer analogy, but it does not capture the fact that primary productivity is a source of energy, rather than an action that depletes energy. Therefore, the correct option is B.

What processes are responsible for the formation of copper ?
Answer:
The high temperatures of volcanic magma creates hydrothermal veins, allowing some of the heat to escape near the upper layers of the Earth's crust. This is why copper is often found in the sedimentary layer, where sand and mud are compressed until they form a layer of sedimentary rock on the surface of the earth
Explanation:
a student is investigating cellular transport. what will most likely occur when the student places a cell that is 95% water inside of a solution that is 100% water?
Cellular transport refers to the flow of substances into or out of the cell across the cell membrane.
When the student places a cell that is 95% water inside of a solution that is 100% water, the cell will achieve net movement and if water continues to enter, it swells up and burst.
When a cell is placed in a hypotonic solution, water flows into the cells and the cell gains volume until it achieves equilibrium. But if water continues to flow in afterwards, it swells up and burst.Learn more about cellular transport: https://brainly.com/question/6949569

What is the difference between weathering and erosion? (Site 1).
Answer:
Weathering and erosion are natural geological processes that act like rocks and soil on the earth's surface, moving and reshaping the earth. Weathering is the breaking down of rocks into smaller pieces by changing the size and structure of the rocks. The forces of nature are largely responsible for this process. Erosion involves processes such as wind, water flow, and ice movement, which results in change from one place to another.

What is meiosis?
In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).
Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent). The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state.
Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.
Nearly every human cell contains 46 chromosomes, 23 of which come from one of our parents and 23 highly similar chromosomes from the other parent. The appropriate number of chromosomes in a cell is crucial.
Therefore, If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis after 3 stages.

Karen has 47 chromosomes but no apparent abnormalities. What is true about Karen?
O A. She has aneuploidy.
O B. She has monosomy.
O C. She will die young.
OD. She has a cleft palate.
Answer:
A. She has aneuploidy.
Explanation:
remember doing this a while back, got it right.
The statement that is true about Karen's abnormality is that she has aneuploidy. Details about aneuploidy can be found below.
What is aneuploidy?Aneuploidy is a chromosomal abnormality whereby an organism possesses a chromosome number that is not an exact multiple of the haploid number of that organism.
In humans like Karen, the haploid number of chromosomes in each gamete cell is 23. This means that the number of chromosomes that is expected to be in the somatic cells is 23 × 2 = 46 chromosomes.
However, according to this question, Karen has 47 chromosomes but no apparent abnormalities. This suggests that she posseses aneuploidy.
