What is the main source of Earth's light?

Answer:

Reproduction.

Explanation:

Reproduction is the process by which organisms produce new organisms of the same type. This can be asexual (an organism not needing a mate to reproduce like certain plants or bacteria) or sexual reproduction (needing a mate to reproduce). Most species can only produce sexually.

Explanation:

Offspring need to carry just one dominant allele from their parents to inherit the polydactyl condition. The probability of the offspring having polydactyly is 50% (2 of the 4) and 50% not having it (normal). This can be expressed as a ratio, 2:2 which can be simplified to 1:1. - found on the internet

There are many rappers out there in the world yet only a few of them are really well known and recognized. Of course this is because they meet peoples expectations. Different people have different opinions on what makes a good rapper. Things that I think make a good rapper is that they need to have good flow, meaningful lyrics that actually make sense and not just rhyme any word with another that doesn't make sense. Another thing is how they are like as a person as well. If they are a pretty decent human being and meets peoples expectations then they will be considered as a good rapper. If the person is not only ignorant but also can't rap well then they are considered bad. Like I said many people have different opinions but these are just mines.

Answer:

The components of the fluid connective tissue are red blood cells, white blood cell and blood platelets

Explanation:

The connective tissues refer to tissues composed of some class of matrix. The blood is considered a fluid connective tissue which is composed of red blood cells (erythrocytes), white blood cell (leukocytes) and blood platelets (thrombocytes). Erythrocytes are cells that contain hemoglobin and whose function is to transport oxygen to the body. Leukocytes are cells involved in the immune responses which act to protect the body against both foreign pathogenic invaders. Finally, thrombocytes are cell fragments that form clots and stop bleeding.

Explanation:

High-energy electrons supply the needed energy to synthesize ATP from the lower-energy ADP in the electron transport chain. So, the correct option is (B).

An electron transport chain is defined as a series of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors through redox reactions and that link this electron transfer with the transfer of protons across a membrane.

Large amounts of ATP can be produced through a highly efficient method called oxidative phosphorylation where ATP is a fundamental unit of the metabolic process. Electrons are transferred from electron donor to electron acceptor thereby producing ATP which is the important step of Electron transport chain.

Thus, high-energy electrons supply the needed energy to synthesize ATP from the lower-energy ADP in the electron transport chain. So, the correct option is (B).

Answer:

Mutations leading to the better attachement of virus to the host cell would allow the virus to spread the infection and leave more progeny. The reproductive fitness of mutant viruses would allow the mutation to spread.

Explanation:

1. The organisms with same resource requirement compete with each other. Viruses are not living things but once inside the host cell, they behave like living things. Rapid multiplication of virus overpopulate the host cells.

2. Genetic variations are added to the viral progeny by random errors during replication of the viral genome. These random variations may  impart beneficial trait, harmful feature or remain neutral. If a random mutation in the SARS-CoV2 virus allows it to adhere better to the cells of the respiratory system, the virus would be better able to infect these cells to spread the infection. Once inside the host cells, the mutant virus would leave more progeny. On the other hand, the wild type virus that lack this mutation would  have lesser chances of entering the host cells and may or may not replicate.

3. The progeny of the mutant virus would compete better with the non mutant ones due to the presence of same mutation.

4. Differential reproduction and more progeny of the mutant virus would spread the mutation among the virus.

Animals use chlorophyll to produce glucose. This is a false statement. Hence, the correct answer is second one . Animals are not autotrophs but heterotrophs.

Photosynthesis is a process in which oxygen and glucose are produced from carbon dioxide and water with the help of sunlight in green plants. This reaction is carried out by the green plant because it consists of chloroplasts.

The chloroplast is the organelle that has chlorophyll pigment, and this pigment is responsible for the photosynthesis process. Due to this, plants are called producers. Animals depend upon the plant for food and are called heterotrophs. Animals cannot do photosynthesis.

In different ecosystems, different producers are present, such as in aquatic ecosystems, where algae and seaweeds perform this function. In terrestrial ecosystems, plants perform this photosynthesis. Consumers feed them depending on the producers, and after both the consumer and the producer die, both are decomposed by decomposers.

Hence, animals use chlorophyll to produce glucose; this is the false statement.

Answer:Through mRNA, the DNA is able to transmit its messages out to other parts of the cell. (Learn more about mRNA here.) Information from the DNA is coded into mRNA which leaves the nucleus of the cell DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies (the white region) and is used by ribosomes (outlined in green). hope this helps have a great night ❤️❤️❤️

Explanation:

There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. Dandelion seeds float away in the wind

We know that the sample is 35% adenine, which tells us that it is also 35% thymine. We know that cytosine and guanine pair together and will be present in equal amounts, so we can divide this final total by 2 to find our answer. The sample is 35% adenine, 35% thymine, 15% guanine, and 15% cytosine.

Answer:

I. Overall magnification (TM) = x40

II. Overall magnification (TM) = x100

III. Overall magnification (TM) = x400

IV. Overall magnification (TM) = x1000

Explanation:

A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.

Mathematically, the overall (total) magnification of a microscope is given by the formula;

Overall magnification (TM) = Eyepiece magnification(EM) X Objective magnification (OM).

I. When EM = x10 and OM = x4

TM = EM * OM

TM = x10 * x4

TM = x40

II. When EM = x10 and OM = x10

TM = EM * OM

TM = x10 * x10

TM = x100

III. When EM = x10 and OM = x40

TM = EM * OM

TM = x10 * x40

TM = x400

IV. When EM = x10 and OM = x100

TM = EM * OM

TM = x10 * x100

TM = x1000
