However, in Earths First Billion years and over the past 4.5 billion years, the main source of water was from comets. We know that comets consist chiefly of chemical compounds that are either gases or liquids at earth-surface conditions: methane is one common component of comets and water is another.

Galactosemia is an inherited genetic condition. Children with this condition cannot break down the sugar galactose, which is part of lactose. Based on the pedigree chart, is this condition a dominant or a recessive disorder? Explain your reasoning.
Answer:
Recessive.
Explanation:
Galactosemia is an autosomal recessive genetic disorder. Recessive genetic disorders occur when an individual inherits a non-working gene from each parent.
There is no chart attached, so the reasoning is just common scientific knowledge. Please attach the chart so I can properly answer the question!
Answer:
It is recessive. Both parents are heterozygous for the trait, but they do not exhibit the disease themselves. If it were a dominant gene, both parents would have the disease if they carried the gene for it.

How does latitude affect a climate zone?
A. Climate zones at high latitudes are cooler because they are closer to the equator.
B. Climate zones at high latitudes receive a lot of precipitation because they are farther C. from the equator.
D. Climate zones at low latitudes receive little precipitation because they are closer to the ocean.
None of the options is entirely correct about latitude and climate zone.
Latitude and climate zoneLatitude is one of the main factors that affect climate, along with elevation, ocean currents, and prevailing winds.
Generally, the farther away from the equator a location is, the colder its climate is. This is because the angle of the sun's rays hitting the Earth's surface is more oblique at higher latitudes, resulting in less heat being delivered per unit of surface area.
However, precipitation patterns are not solely determined by latitude. They are also affected by other factors such as prevailing winds, ocean currents, and topography. For example, areas located on the windward side of a mountain range tend to receive more precipitation than those on the leeward side, regardless of their latitude.
Therefore, while latitude is an important factor in determining climate zones, it does not fully determine precipitation patterns or temperature.

What is a scientific theory? What is a hypothesis? How are they similar? How do they differ?
Answer: Scientific theories can be backed up with evidence/data (the evidence that backs the theory isn't common knowledge to everyone yet), while a hypothesis is just an educated guess, meaning that you are making a prediction based on something already known.
They are both similar in the sense that they are questions that are answered by facts, but theories are answered with factual evidence rather than factual reasoning (hypothesis).

O mRNA is made in large quantities in frequent batches.
OmRNA is made in small quantities in infrequent batches.
O mRNA is made in large quantities in infrequent batches.
O mRNA is made in small quantities in frequent batches.
Answer:
O mRNA is made in small quantities in infrequent batches.
Explanation:
mRNA is made in small quantities in infrequent batches because the affinity of positive transcription is lower and affinity of negative transcription is higher which is responsible for production of mRNA from DNA molecule. Transcription is a process in which the information that is present in DNA molecule is copied to new mRNA molecule. Positive transcription factor is a promoter which promotes the initiation of transcription in order to enable RNA polymerase while negative transcription factor is a repressor protein.
Why is digestion of fats difficult as compared to that of other nutrients?
This is because fats are insoluble in water and therefore are more difficult to digest than any other nutrients. They also present as large globules.
Hope that helped!!! k
Answer:
Fats take longer time to digest than carbohydrates. Fats can't be digested easily as its insoluble in water and are presented as large globules. The bile juice that gets secreted breaks down the fat from bigger droplets into smaller ones.

Answer:
4, based on the assumption that the R allele is dominant over the r allele, and that the T allele is dominant over the t allele.
Explanation:
Any bush with a dominant petal color allele (R) will have red petals. This includes Rr and RR.
Any bush with a dominant bush size allele (T) will have a tall bush. This includes Tt and TT.
The only way to acquire a short bush or pink petals is to have two recessive alleles together (tt, rr).
RRTT, RrTT, RRTt, and RrTt -> red petals with tall bushes
RRtt, Rrtt -> Red petals with short bushes
rrTt, rrTT -> pink petals and tall bushes
rrtt-> pink petals with short bushes.
These are the four phenotype variations possible in this dihybrid cross.

How are the proteins inside your body affected by the presence of water and other molecules?
Answer:
Our body is constitute of several essential molecules such as proteins, fat, carbohydrate, water, and other molecules.
Each molecule has some of the impact of other molecules in the body. Impact of water and other molecules on proteins inside the body are as follows:
Proteins have ligand-binding site and water provide stability to the ligand-binding site of proteins through its hydrogen bonds.Conformational flexibility and transitions of proteins are due to the presence of water molecules in it.Disbalance in the pH of body due to changing concentration of sodium-potassium ions can denature the protein. Enzymes present in the body can control the rate of formation of proteins in the body.
What is desertification?
a.
method of using desert land for agriculture
b.
the process of turning arable land into deserts
C.
drying up of stream beds and lakes
d.
the expansion of current deserts land areas
Answer:
B
Explanation:
I believe it's B because desertification is the process of land being turned into deserts due to many factors like animal grazing.
Desertification means the process of turning arable land into deserts, which is the second option. Desertification is a process in which agricultural land is affected the most, resulting in the land having fewer nutrients.
What is desertification?Desertification is a process in which arable land is affected, and as a result, crop production is reduced. Desertification is the result of many factors, such as climate change, rapid urbanization, population growth, global warming, etc. The less water, nutrients, and microbes there are in the soil, the more likely it is that the land will become a desert.
Microbes in the soil become extinct as a result of climate change, causing crop patterns to shift and more land to become desert. Global warming causes temperatures to rise and many species to become extinct, exacerbating the problem.
Hence, desertification means the process of turning arable land into deserts, which is the second option (b).
