Individuals in a species have genetic variation that can be passed on to their offspring
Answer: Genetic variation within a species can result from a few different sources. Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. ... As a result, the tree-colored moths are more likely to survive, reproduce, and pass on their genes.

A) It causes precipitation to form and collect in the ocean.
B) It warms the clouds in the sky and causes precipitation.
C) It warms the water on the Earth's surface and causes it to evaporate.
D) It warms the water vapor in the clouds and turns it into water droplets.
Answer:
d
Explanation:
It warms the water vapor in the clouds and turns it into water droplets.
The process involved in the formation of rains is option B, it warms the clouds in the sky and causes precipitation.
What is water cycle ?Water cycle is a geological phenomenon through which the water content in the atmosphere and hydrosphere is balanced. The heat radiated from sun warm up the water bodies make the convection currents that evaporates water.
The water vapor rise to the atmosphere and maintain the air moisture. When this vapor cools down they condense and precipitates as rain, snow or sleek.
This process involves the transfer of heat energy and matter. Here, the matter is water itself with its three phases. Hence, option b describes the cause of rain.

why CO2 still being produced for a few minutes after death?
Explanation:
As best as anyone can gauge, cell metabolism likely continues for roughly four to 10 minutes after death, depending on the ambient temperature around the body.
During this time period, oxygenated blood, which normally exchanges carbon dioxide with oxygen, is not circulating. Thus, cell respiration—which uses oxygen to make cellular energy while creating carbon dioxide as a by-product—creates carbon dioxide that is not transported out of the cell. This lowers the pH of the cell, resulting in an acidic intracellular environment. This acidic environment causes intracellular membranes to rupture—including those around the cell's lysosome, which contains enzymes for digesting everything from proteins to fats and nucleic acids. Once the membranes have burst, these enzymes are released and begin to digest the cell from the inside out. This process is known as autolysis (or self-digestion).

8. Which of these is the direct result of an error in the transcription of a DNA
nucleotide?
A. Amino acids do not bond to tRNA.
B. Transportation of mRNA does not occur.
C. The nuclear membrane is ruptured.
D. RNA sequence is incorrect.
CLEAR ALL
Answer:
D. RNA sequence is incorrect.
Explanation:
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
When a RNA sequence is incorrect, it leads to an error in the transcription of a DNA nucleotide.
This ultimately implies that, an error in the transcription of a DNA nucleotide is the direct result of an incorrect codon sequence (RNA nucleotides).
how does nonradom matting affect the gene pool
Answer:
I think it's, the nonrandom mating is defined solely in terms of departures from HW proportions for neutral alleles, without reference to phenotypes. The impact is measured in terms of genetic parameters, such as genetic variance, expected gene flow, and Δ F, assuming the infinitesimal model and mass selection.

Specialized cells have different dna from other specialized cells
Answer: for example in a nerve cell are different from the genes that are expressed in a muscle cell. Both cells have the same DNA, but expressing different genes generates different cell types.
Explanation:
Jill uses a magnet to pick up a nail. Then, she touches the nail to a paper clip and picks up the paper clip. What will most likely happen when she pulls the magnet away from the nail?
The paper clip will stay attached to the nail because the nail is now a permanent magnet.
The paper clip will stay attached to the nail because the paper clip is now a permanent magnet.
The paper clip will fall off of the nail because the nail was only a temporary magnet.
The paper clip will fall off of the nail because the nail is now magnetized in the opposite direction.
Answer:
C but see below.
Explanation:
e. The paper clip will likely fall off because it wasn't attached to the nail long enough to be magnetized.
The same answer would apply to the nail. It likely was not held onto the magnet long enough to pick up a magnetic force that would be strong enough to overcome the gravitational force pulling on the clip.
Of the four answers you have given us, I would agree with C. But as I've argued above, the real reason is likely there.

C

Thank you!
Answer:
I think it is maintaining water balance since transpiration in plants is basically when the plants roots absorb water and then release the water in the form of vapour (Don't know much about plants but I think maintaining water balance is most probably the answer)
Does DNA in animals and plants use the same nitrogenous base pairs?
Answer: There are pretty obvious differences between plants and animals, but – at the chemical level – the cells of all plants and all animals contain DNA in the same shape – the famous “double helix” that looks like a twisted ladder. What’s more, all DNA molecules – in both plants and animals – are made from the same four chemical building blocks – called nucleotides.

In chickens, Black feathers (B) are dominant over white feathers (b). Complete the Punnett
Square for the following cross:
Mother: BB
Father: bb
What percentage of offspring will be Black?
What percentage of offspring will be White?
Answer:
(attached Punnett square below)
100% of the offspring will have black feathers
0% of the offspring will have white feathers
Explanation:
All the possible offspring have the genotype Bb, and since B (black) is dominant it will be the phenotype regardless of the presence of a b allele.
Therefore, all the offspring will be black (100%) and since none of the genotypes are bb there's no chance for white feathered chickens (0%)
hope this helps!

Show are meiosis and mitosis different
Answer:
The purpose of mitosis is the creation of diploid somatic cells and the purpose of meiosis is the creation of haploid sex cells.
Explanation:
Mitosis takes place in somatic, or body cells, and meiosis takes place in gametes, or sex cells. The purpose of mitosis is growth and repair, while the purpose of meiosis is creating gametes with half the normal number of chromosomes and is for reproduction. Mitosis goes through Interphase, Prophase, Prometaphase, Metaphase, Anaphase, Telophase, and Cyokinesis once to produce two genetically identical diploid somatic daughter cells. Meiosis goes though that twice (Meiosis I and Meiosis II) to produce 4 genetically unique haploid gametes. It has stages (Prophase, Metaphase, Anaphase, and Telophase) such as Prophase I and Prophase II because meiosis occurs twice. Another difference is that mitosis happens throughout your life and meiosis occurs before females are born and throughout a males life.

Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another. What experamint did he perform to test this idea
Answer: He performed dihybrid crosses
Explanation:
Dihybrid cross is simply refered to as a cross that is done for two genes that are different with regards to their traits. For example, if we cross two maize plants which have different shapes and color let's say that one is white and round while the other maize's colour is yellow and its shape is wrinkly.
Since Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another, the experiment performed will be dihybrid crosses.
