The correct descriptions that help to define luminosity are How much energy is emitted per second, How much surface area the object has, and The amount of brightness of an object.
What is the energy content of luminosity?An object's luminosity, which is the quantity of energy it emits over a predetermined period, is a measurement of its inherent brightness. Since it simply measures the object's power output, it can be expressed in units like Watts.
What factors affect luminosity?A star's luminosity, or the total amount of energy it emits each second, is determined by two factors: The stellar photosphere's "Effective Temperature," T. the star's total surface area, which is influenced by its radius, R.
What three things have an impact on luminosity?The size, temperature, and distance of a star are the three variables that determine how bright it seems to us on Earth. The brilliance of a star is measured by its magnitude.

Which of the following is an advantage of meiosis and sexual reproduction?
A. Meiosis ensures that offspring will not inherit any genetic disorders.
B. Meiosis ensures that offspring are genetically identical as their parents.
C. Meiosis ensures that offspring will have identical phenotypes to their parents.
D. Meiosis ensures a wider variety of genetic variation.
Answer:
D. Meiosis ensures a wider variety of genetic variation.
This happens above all thanks to the Crossing over, the process in which the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids results in recombinant chromosomes.

Which is the best explaination for how chemical energy is transferred with cells
Answer:
Inside the cell, each sugar molecule is broken down through a complex series of chemical reactions. As chemical energy is released from the bonds in the monosaccharide, it is harnessed to synthesize high-energy adenosine triphosphate (ATP) molecules. ATP is the primary energy currency of all cells.

C: population of species
D: animal species only
Answer:
Can confirm it is A
Explanation:
The process of the natural selection produce change occurs when there is the individual member of species.
What is species and natural selection?It refer to the group of the organism where it should be reproduced in a natural way with one another and also developed the fertilization off-spring.
The organism that does reproduction at a se-xually only, the species population, and the animal species should not change the natural selection.
It is the process via which populations of living organisms should be adapt and change.

Identify and analyze the way fossil fuel combustion has changed the composition of Earth's atmosphere, and the way this change has affected climate.
Answer:
Increases the concentration of carbondioxide gas in the atmosphere.
Explanation:
The burning of fossil fuel increases the concentration of carbondioxide gas in the atmosphere because when the fossil fuel burns, carbondioxide gas is released. Carbondioxide gas is a greenhouse gas which goes up in the atmosphere and make a layer which allow light radiation to the earth but prevent it from going to the space after reflection which causes increase of surface temperature of the earth leads to global warming.
The fossil fuel combustion has increased the concentration of carbon atoms in the atmosphere.
What is concentration of carbon?
Concentration of carbon means the amount of carbon in the atmosphere.
The amount of carbon dioxide has increased substantially after the industrial era.
The concentration of carbon is 400 parts per million in more traffic areas.
The level of indoor carbon depends upon the number of person present there.
Thus, the fossil fuel combustion has increased the concentration of carbon atoms in the atmosphere.

why is there a need to protct our forests coral reefs and mangrove swamps?
Answer:
If we don't protect our forests, they get either get burned or cut down so that people can build more places or more space for crops. If we have little forest, there will be little oxygen in the air and we will die, global warming will also increase. Coral reefs are meant to protect the sea from inhumane acts which pollute the sea and cause marine animals to die, if they die the sea will be very polluted and marine animals might become extinct. Mangrove swamps are a habitat to many different animals, if they are gone the animals will have no habitat to live in and might soon face the consequences of extinction.

If a mosquito cell has 3 chromosomes, is it haploid or diploid?
Answer:
If an orangutan cell had 24 chromosomes, then the cell is diploid or haploid (circle one). If a mosquito cell had 3 chromosomes, then it would be a gamete or a somatic cell (circle one).
mark me as brainlist please
All mosquitoes have six diploid chromosomes (2N = 6), and their chromosomes are either submetacentric or metacentric, mosquito cell has 3 chromosomes and is haploid.
What is the difference between haploid and diploid?Three pairs of chromosomes make up the Anopheles mosquito's chromosomal complement: two sex chromosomes As a consequence, when a sperm and egg cell join during fertilization, the resultant zygote has 46 chromosomes.
The number of chromosomes and their shape in mosquitoes are extremely similar mosquito cell has 3 chromosomes, and are haploid.
Therefore, to go from haploid to diploid cells, we only need to double the number of chromosomes. This quantity is denoted by the abbreviation 2n, where n is the number of chromosomes.

pls help!!! osmosis help needed!!
Answer:
1. 10% 2. 90% 3. 80% 2. Yes 3. Into 3. Swell 6. Hypotonic
Explanation:
1. Given the image, it shows there is 10% glucose outside the cell.
2. Because there is 10% glucose outside the cell, you can automatically conclude that there is 90% of water outside. (You want it to equal to 100%. So, 10 + 90 = 100)
3. Given 20% glucose inside the cell based on the image, you can conclude that there is 80% water inside the cell.
2. Yes, osmosis will occur. Osmosis is the movement of water from a higher concentration to a lower concentration. In this case, there is more water outside the cell than in. So, yes, osmosis will occur.
3. The water will move into the cell (There's less water inside, and more outside, so of course, the water will move in).
3. The cell will swell, since water is getting moved in.
6. This is a hypotonic solution. Definition of a hypotonic solution: The concentration of solutes outside the cell is less than that of water. Hypotonic solutions always swell, as water moves into it.

Which gene mutation would have the smallest impact on a protein's amino acid sequence?
Answer:
Point mutation
Explanation:
Point mutation is a kind of mutation that involves a single nucleotide base. Generally, mutation is any alteration that occurs to the genetic sequence of an organism, however, point mutation involves only one base of the numerous in the sequence.
Point mutation can be an insertion, substitution, deletion etc, but it is the gene mutation that would have the smallest impact on a protein's amino acid sequence. This is because the change to the genetic sequence involves a single base.
