Answer:
The Hertzsprung-Russell Diagram is a graphical tool that astronomers use to classify stars according to their luminosity, spectral type, color, temperature and evolutionary stage. Stars in the stable phase of hydrogen burning lie along the Main Sequence according to their mass.
Explanation:
When a cell with 18 chromosomes divides by meiosis, the result would be four daughter cells, each with 9 chromosomes, option(c). This is because meiosis reduces the number of chromosomes in each daughter cell by half.
The best description of the expected daughtercells when a cell with 18 chromosomes divides by meiosis is: The result would be four daughter cells, each with 9 chromosomes. This is because meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell. The process of meiosis begins with a parent cell that is diploid, meaning it has two complete sets of chromosomes. During meiosis, this cell undergoes two rounds of division, resulting in four haploid daughter cells, with each containing half the number of chromosomes as the original parent cell. In this case, the original cell has 18 chromosomes, so each of the four daughter cells will end up with 9 chromosomes, option(c).

Question: A cell with 18 chromosomes divides by meiosis. Which of the following statements best describes the expected daughter cells?
a. The result would be two daughter cells, each with 18 chromosomes.
b. The result would be four daughter cells, each with 18 chromosomes.
c. The result would be four daughter cells, each with 9 chromosomes
d. The result would be two daughter cells, each with 9 chromosomes.
Answer: there are four daughter cells. Each daughter cell has different characteristics from the parent
Explanation: did it
Answer:
Excessive consumption is understood as an uncritical purchase. Thus, people who buy compulsively do not analyze the social and personal consequences of the purchase.
Explanation:
The warning about the risks of overpopulation has been the subject of books and discussions for many decades. Today the imbalance caused by overconsumption generates international debates, conferences, targets for reducing greenhouse gases, water consumption, installation of clean energy, among other internationally announced commitments.
This is because excessive consumption is made at the expense of natural resources. The more industrialized products are manufactured, the more natural resources are consumed. The more we buy these products, the more they are manufactured.
In view of the improvement in the quality of life and the higher gains, the population consumes a lot and directly interferes in the extraction of resources. In the consumption level data between rich and poor countries, the disparity in which the former vastly outweighs the latter is clear. Not to mention that rich countries encourage the extraction of resources in underdeveloped countries to meet their needs, since their resources have been depleted for a long time.
Answer:
meiosis
Explanation:
Down syndrome is an abnormality that occurs on chromosomes 21, it occurs because chromosomes 21 cannot be separated in meiosis, the pair of chromosomes 21 do not separate and go together to one of the daughter cells. In this way, the oocyte or the resulting sperm will have 24 chromosomes instead of 23. When in conception that oocyte or sperm joins the germ cell of its partner that contributes the 23 chromosomes, the total sum of chromosomes that will have the first cell of the new conceived being will be 47.
Answer:
The mutation observed in the down syndrome occurred as a result of a abnormal and non disjuncted meiosis.
Explanation:
Howbeit, mutation can be described as any heritable change of the base-pair sequence of genetic material.
Down syndrome also described as trisomy 21 is a medical condition caused by a chromosomal excess, whereby the patients bear a certain resemblance to the Mongoloid race, such as a small head and tilted eyelids, and typically have a delay in cognitive ability and physical growth.
Meiosis is one that describes the cell division process of a diploid cell into four haploid cells, which develop to produce gametes.
The chromosomal mutation of nondisjunction in down syndrome describes how a pair of chromosomes is not fully separated during meiosis, resulting in the gamete having an extra chromosame (or none at all).

because the ocean has many more molecules than a pot of water
B
because ocean water has a higher temperature than boiling water
C
because the salt in the ocean causes ocean water to hold on to more heat
D
because molecules of ocean water moves more slowly than those of boiling water
Answer:
A.bevause the ocean had more molecule than a pot of water.
The ocean contains more heat energy than a pot of boiling water because it has many more molecules.
The correct answer is A) because the ocean has many more molecules than a pot of water.
In terms of heat energy, the total amount of energy in a substance is directly proportional to the number of molecules it contains. Therefore, the ocean, which is much larger than a pot of boiling water, contains a significantly higher number of molecules, resulting in more heat energy.
For example, if we compare a small pot of boiling water to the vast ocean, the ocean contains a much larger volume of water, and therefore, a greater number of molecules that contribute to its heat energy.
