Answer:
erosion will occur in that part of the hill.
Explanation:
Rainstorm refers to the rainfall which occurs with storm. The rainstorm is responsible for erosion of the soil where there is a slop which removes the upper layer of the soil and water comes to downward in the form of mud flood which destroy everything. At the hill, rainstorm will occur which does not causes erosion due to rocky surface but when this water goes to those areas where soil is present. This water takes that soil with itself downward and erosion of the soil will occur.

Why is a supply of oxygen important for muscle contraction?
Answer:
For muscle contraction to take place oxygen is needed. ... Oxygen allows the body to convert glucose into ATP more efficiently without creating a waste product.
Cellular respiration is the process in which your muscles use oxygen to produce ATP energy. ... Whether you're exercising or not, the oxygen in your body is used to break down glucose and create the fuel for your muscles called ATP
ATP= Adenosine triphosphate

What is the smallest or most specific level of organization organization you and your neighbors all have in common
Answer:
The cell
Explanation:
The smallest or most specific level of organization that all living organisms (including myself and my neighbors) have in common is the cell.
This is in accordance with the cell theory which has three basic components, including:
1. The cell is the basic unit of life
2. All living organisms are made up cells
3. Cells arose from pre-exsiting cells.
Other levels of organisation include tissues which are group of cells specialized for a certain function, organs which are group of tissues serving similar function, and systems which are group of organs working together as a unit.

Identical twins are produced from the same sperm and egg (which splits after the first mitotic division), whereas fraternal twins are produced from separate sperm and separate egg cells. If two parents, one with brown eyes (a dominant trait) and the other with blue eyes (the recessive trait) produce one twin boy with blue eyes, what is the probability that a fraternal twin will transmit the blue eye allele to his or her offspring
Answer:
This is 25%
Explanation:
Analysis, Since the dominant brown eyed parents produce blue eye child, this shows they are heterozygote dominant
However,this fraternal twin is not genetically identical, due to the blue eye color,(recessive) but the fact remain that they are the parents.(because he inherited the recessive allele from each of the parent)Therefore the probability is 25%.
This is because he is the only one out of the 4 kids( based on Mendelian fashion) this is 1/4,25%
Fraternal tweens are produced from different maternal and paternal gametes. The blue-eyed tween has 100% probability of transmitting the blue-eyes allele to the offspring, while the brown-eyed tween has 50% probability.
Available data:Fraternal twins are produced from separate sperm and separate egg cells.Brown eyes ⇒ Dominant traitBlue eyes ⇒ Recessive traitWe will name B to the dominant allele that codes for brown, and b to the recessive allele that codes for blue eyes.
So, the possible genotypes and phenotypes are
Gentoype Phenotype
BB Brown eyes
Bb Brown eyes
bb Blue eyes
Solving the problemThe parent with blue eyes must be only bbThe parent with brown eyes must be either BB or BbFor the twin boy to have blue eyes, he must have received two recessive alleles, one from the mother and one from the father.
So the father is heter0zyg0us for brown eyes, Bb.
Cross: Bb x bb
F1) 1/2 of the progeny is expected to be brown-eyed, Bb
1/2 of the progeny is expected to be blue-eyed, bb.
So we have two genotypes for the tweens, Bb and bb.
bbThe bb tween has blue eyes and is h0m0zyg0us recessive for the trait. So the probability that this fraternal twin will transmit the blue eye allele to his or her offspring is 100% This tween can only provide recessive alleles to his or her progeny. BbThe Bb tween has brown eyes and is heter0zyg0us for the trait. So the probability that this fraternal twin will transmit the blue eye allele to his or her offspring is 50% This tween can provide one dominant or one recessive allele to his or her progeny.So, the blue-eyed tween has 100% probability of transmitting the blue-eyes allele to the offspring. The brown-eyed tween has 50% probability of transmitting the same allele to the descendants.

Make a prediction: During the first trial, you will not be able to see how many people have the disease until the end. If no students are immune, how many do you think will have the disease at the end? __________ out of 20
Answer:
all 20
Explanation:
It is impossible to know how many individuals will have the disease at the end without knowing other factors such as the condition where the subjects are being held, trial specifications and safety measures, etc. Based on the information provided, the best prediction that can be made is that all 20 subjects will have the disease. This is because since none of them are immune the disease will spread between the patients/subjects through contact or testing equipment.

Which of the following factors might cause checkpoint genes to interrupt cell division? Check all that apply. Neurological signals sent from fear responses in an organism tell the cell to stop. The cell's DNA has been damaged somehow. The cell's DNA was replicated incorrectly.
Answer:
Neurological signals sent from fear responses in an organism tell the cell to stop. The cell's DNA has been damaged somehow. The cell's DNA was replicated incorrectly.
Explanation:
All the three options given can cause checkpoint genes to interrupt cell division.
Checkpoint genes are transcription genes that control cell cycle and sense defects during cells processes like DNA replication, segregation e.t.c and create response till the defects is repaired in the DNA. The important of checkpoint is that it ensure enough nutrients are available to support for division, ensure that the DNA has not been damaged, ensure that cells DNA is copied correctly and make sure cells have enough RNA for their protein synthesis.
Checkpoints genes can interrupt cell division if the dna is damaged, Dna is copied incorrectly and neurological signal sent from fear responses in an organisms tell the cells to stop.
Answer:
The cells DNA has been damaged somehow and The cells DNA was replicated incorrectly
Explanation:
sometimes, these checkpoint genes are mutated or damaged and, thus, are unable to tell a damaged cell to stop dividing. When this occurs, the damaged cell gives rise to many damaged cells, which in turn create more damaged cells. These dividing cells form a NEOPLASM

A woman who has blood type A positive has a daughter who is type O positive and a son who is type B negative. Rh positive is a trait that shows simple dominance over Rh negative and is designated by the alleles R and r, respectively. A third gene for the MN blood group has codominant alleles M and N. If both children are of blood type M, list all of the possible parental phenotypes
Answer:type A
Explanation:
Possible parental phenotypes could be mother with blood type A Rh positive and MN or MM while the father will have blood type B Rh negative and MN or MM type.
What is blood typing in humans?Blood typing is a method to tell what type of blood group or blood an individual has. Blood typing is done so a person can safely donate hos or her blood or receive a blood transfusion from another person. It is also done to see if a person have a substance called as the Rh factor on the surface of the red blood cells.
Blood typing in humans is an example of codominance and multiple allelism. Blood group A and B are codominant and O is recessive allele. Rh negative is recessive over Rh positive blood group. A third gene for the MN blood group is codominant, in which M and N are codominant.
In the given question, both the children are of blood type M. In this case, M and N are codominant over each. Therefore, the possible parental combinations can be MN × MN or MM × MN.

Which describes an atom that has fewer neutrons than protons and more electrons than protons? negative compound positive compound positive ion negative ion
Answer:
Negatively charged ion
Explanation:
Negatively charged ions are called anions and they have more electron than than protons and more protons than nuetrons.
When an atom has fewer neutrons than protons and more electrons than protons, such an atom is said to be an anion. Hence, it is negative ion.
Depending on the number of proton and electron, there are 3 types of atoms:
Neutral atoms in which the proton and electron numbers are balancedCation in which the proton number is more than the electron numberAnion in which the electron number is more than the proton numberIn this case, the atom has more electrons than protons and, therefore, is an anion. The excessive electron makes such atom to be negatively charge.
Therefore, an atom that has fewer neutrons than protons and more electrons than protons is a negative ion.

Assume that plant weight is determined by a pair of alleles at each of two independently assorting loci (A and a, B and b) that are additive in their effects. Further assume that each allele represented by an uppercase letter contributes 4 g to weight and that each allele represented by a lowercase letter contributes 1 g to weight. If a plant with genotype AA BB is crossed with a plant with genotype aa bb, what weights are expected in the F, progeny?
a.1g
b. 4g
c. 8g
d. 10g
e. 16g
Answer:
10g
Explanation:
A cross between genotype AA BB is crossed with a plant with genotype aa bb will produce
Parent genotype:AABB x aabb
Gametes: AB x ab
F1 generation - AaBb
Since an uppercase letter contributes 4 g to weight and each allele represented by a lowercase letter contributes 1 g to weight.
Thus, 4+1 + 4 + 1 = 10g
An unfertilized egg cell has six chromosomes. After fertilization, how many chromosomes should the zygote have?
Answer:
12 chromosomes, because the basic (haploid) number of chromosomes is 6 (n: 6)
Explanation:
The unfertilized egg contains a basic (haploid) number of chromosomes (n), being in this case 6. In humans, for example, the gamete haploid cells have a basic n content of 23 chromosomes, while in somatic cells this DNA amount is duplicated (2n), being therefore 46 chromosomes that are organized into 22 pairs of autosomal chromosomes and two sex chromosomes (X and Y).
