Which of the following best describes the genetic complement in each
daughter cell at the conclusion of meiosis?
A. A haploid set of chromosomes that are a recombination of the
parents' chromosomes
B. A diploid set of chromosomes that are identical to the parents'
chromosomes
C. A diploid set of chromosomes identical to the other daughter cells'
chromosomes
D. A haploid set of chromosomes that are identical to the parents'
chromosomes
Answer:
A
Explanation:
Meiosis end in four daughter cells that are haploid and contain half the chromosomes as the parent cell and genetically different from the parent cell and from each other, so A would be the right answer.
A haploid set of chromosomes that are a recombination of the parents' chromosomes best describes the genetic complement in each daughter cell at the conclusion of meiosis.
What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.
Moreover, meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.
Meiosis is important for three main reasons: it allows sexual reproduction of diploid organisms, it enables genetic diversity, and it aids the repair of genetic defects.

through facilitated diffusion. How will they be transported?
A. The molecules will move through channels in the membrane hy
proteins from inside the cell to outside the cell.
B. The molecules will move directly across the membrane from
inside the cell to outside the cell.
C. The molecules will move through channels in the membrane proteins from outside the cell to inside the cell.
D. The molecules will move directly across the membrane from the outside the cell to inside the cell.
Answer:
The molecules will move directly across the membrane from
inside the cell to outside the cell.
Explanation:
Ape-x
Facilitated diffusion is the type of transportation that moves the ions and the molecules. The molecules are transported directly through the membrane from inside to outside. Thus, option B is correct.
What is facilitated diffusion?Facilitated diffusion is the transportation of the molecules and ions across the cell membrane along the concentration gradient. It is a passive transport that involves the movement down the gradient.
The molecules are transported by the membrane proteins that facilitate their movement from inside of the cell towards the outer space of the cell. Unlike simple diffusion, facilitated diffusion uses energy in the form of ATP.
Therefore, the molecules present inside the cells will move directly towards the outside of the cell.

Which type of precipitation is most likely to occur when both air and cloud temperatures are above freezing?
A) Rain
B) Snow
C) Hail
D) Sleet
Answer:
it should be A or rain to be specific
Answer:
rain
Explanation:
If the ar is above freezing, the precipitation will most likely be rain. If the air is below freezing, the precipitation will most likely be snow. When air temperature is only a few degrees above freezing, precipitation may fall as sleet. Hail is most commonly formed within the cumulonimbus clouds of thunderstorms.
Mary poured 40,000 cm3 of water into an aquarium that
is shaped like a rectangular box. If the length and width
of the aquarium are 40 cm and 80 cm, respectively, what
is the height, in centimeters, of the water in the
aquarium?
Answer:
The correct answer is - 12.5 cm3.
Explanation:
Given:
volume = 40000 cm3 (aquarium an hold water)
length and width = 40 cm and 80 cm
Height = ?
Formula:
Volume = length*width*height
Solution:
Putting the value in the formula -
40000 = 40*80*h
h = 40000/3200
h = 12.5

Answer:
1. C
2. D
Explanation:
In an experiment, which aims at solving a particular problem or answering a scientific question about nature, the scientific method is employed. The scientific method contains the following steps:
- Making an observation.
- Asking a question.
- Formulating a hypothesis
- Testing the hypothesis via experimentation
- Analyzing the results
- Conclusion
According to question 1, the PURPOSE of an experiment portrays what is about to be done in a question format. For example, a purpose can go this: What will be the effect of pesticides on the growth of cowpea?. Furthermore, the PURPOSE helps make a research and state a hypothesis in the next step.
- In the analysis of result, the qualitative or quantitative approach is used. The QUANTITATIVE method involves the use of numbers or numerical data to express the outcome or result of the experiment. By counting or measuring, a numerical data is collected and given a unit depending on what is being measured

A certain species of trilobite is known to have lived 300 million years ago. If this index fossil was found in a rock layer containing other fossils, what could you infer about the other fossils
a The rock layer killed the trilobite and the other fossils
b The other fossils are about 300 million years old
c The organisms that formed the other fossils are still living.
d The rock layer formed before the trilobite and other organisms
Answer:
b The other fossils are about 300 million years old
Explanation:
From the description of the problem given, we can correctly conclude that the other fossils are about 300 million years old and even the rock layers formed around that period in time too.
Fossils are the preserved remains of organisms that has once lived. Through the principle of relative dating we can determine the age of fossils and those of other related ones. According to the principle of fossil and fauna succession, "fossils succeed one another in a predetermined form". So, the fossils occurring together within the rock layers are of the same age.Someone please help I took the picture this is my last question on my homework
Answer:
According to the image that represents a cell in the human body, the true statement is that structure 4 is the cell membrane that provides exchange of O₂ & CO₂.
Explanation:
In cells, the cell membrane acts as a semi-permeable barrier to the passage of substances, including nutrients and oxygen (O₂).
One of the functions of the cell membrane is to allow the exchange of O₂ —necessary for the cell— and carbon dioxide (CO₂), a product of cell metabolism that must be removed.
In the image, the structure identified with the number 4 corresponds to a cell membrane of human cells that provides this gas exchange.
The other options are not correct because:
Structure 1 is a ribosome, not a chloroplast. Structure 2 is the nucleus, not a vacuole containing DNA. Structure 3 is a mitochondria, but protein synthesis does not occur there.Biotic and abiotic factors are both essential in shaping an ecosystem.
