What is erosion explained?
Erosion is the geological system in which earthen materials are worn away and transported by means of natural forces consisting of wind or water. A similar technique, weathering, breaks down or dissolves the rock, but does no longer involve movement.
What are erosion and weathering?Weathering is the breaking down or dissolving of rocks and minerals on Earth's floor. as soon as a rock has been damaged, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, flora, animals, and modifications in temperature are all dealers of weathering and erosion.

C. Coronary artery disease can reduce blood flow to the heart and cause heart attacks.
D. Heart attacks occur when coronary artery disease is treated.
C) Coronary artery disease can reduce blood flow to the heart and cause heart attacks
CAD (or atherosclerosis) affects the vessels that supply blood to the heart muscle. It is caused by deposits of calcium, fat, cholesterol and fibrous tissues, which makes the lumen of arteries narrower. And due to inadequate supply of blood, the heart muscles get damaged. This can lead to a heart attack!

The immunoglobulin light chain does not have a D segment. In humans, there are two different possible light chain proteins, termed kappa and lambda. Assume that there are 35 V segments and 5 J segments in the human kappa light chain region, and there are 30 V segments and 4 J segments in the human lambda light chain region. How many possible light chain genes can be created from these different segments, simply due to combinatorial diversity
Answer:
295
Explanation:
Antibodies (also known as immunoglobulins) are immune system-related proteins that circulate in the bloodstream in order to recognize pathogenic harmful substances (antigens) and neutralize them. An antibody consists of two immunoglobulin heavy chains and two immunoglobulin light chains. There are two types of immunoglobulin light chains: 1-the kappa (κ) light chain, which is encoded by the immunoglobulin κ locus; and 2-the lambda (λ) light chain, which is encoded by the immunoglobulin λ locus. The immunoglobulin light chain is a multidomain protein composed of two domains: 1- the N-terminal variable (V) domain and 2-the C-terminal constant (C) domain. V(D)J recombination is a type of somatic rearrangement process by which T and B cells can assemble different gene segments, which are referred to as variable (V), diversity (D) and joining (J) gene segments. In the question above the number of possible genomic recombination events between immunoglobulin gene segments can be calculated as >> (5 x 35) + (4 x 30) = 295.

Explain the self-correcting nature of science.
The notion of a self-correcting science is based on the naive model of science as an objective process that incorporates new information and updates beliefs about the world depending on the available evidence. When new information suggests that old beliefs are false, the old beliefs are replaced by new beliefs.
There are a lot of cells and tissues that support the developing embryo. How do you think this changes if the mother is a litter bearing animal such as cat, dog or mouse? (be sure to provide references to defend your answer
Answer: The cells and tissues support embryonic development in mammalian offsprings as these cells have the capacity to divide and differentiate.
Explanation:
Since the time from copulation till delivery of fetus several changes occur in the body of the mammalian mother including animals like cat, dog, and mouse to support the pregnancy. There are specialized totipotent cells which are proliferating specialized cells they have tendency to divide quickly and differentiate into functional types so that they can become a specialized organ or part of the body. If take an example of human which is also mammal in mother body after conception the egg gets fertilized to form sperm which changes to embryo the embryo divides and differentiate to form blastocysts and further divides and differentiate in several stages to become fetus.

In order to attract females, the male Bowerbird of Australia constructs elaborate structures called "bowers" on the forest floor. His bower is made from twigs, leaves, and moss, and is decorated with colorful ornaments such as feathers, pebbles, berries, and shells. If a female is sufficiently impressed with a bower, she will mate with the male who built it. This is an example of which of the five evolutionary forces? mutation gene flow non-random mating genetic drift
Answer:
non-random mating
Explanation:
In animals, most cases of non-random matings are related to behavior. There are three main possible ways of non-random mating:
Harem reproduction ⇒ Dominant males mate with their group of femalesDiscriminated mating ⇒ Individuals mate with genetically similar partnersSexual selection ⇒ One of the couple members chooses the other one.Sexual selection
In many bird and mammal species, and even in some fish species, one of the sexes selects the other one to mate. In general, the one that chooses is the female.
Intrasexual competition between males to get access to females plays a significant role in sexual selection. Males can develop weapons that make them greater fighters.
There is also intersexual selection, in which members of each sex apply selective pressures on the other sex, modeling their phenotype by choosing partners.
As notorious structures and behavior make males be more vulnerable to predation, sexual selection seems to operate against other types of natural selection, as it might affect males´ survival.
However, there seems to be a compensation between sexual selection and natural selection.
----------------------------------------------------------------------------------------------------------
In the exposed example, the construction of elaborated and noticeable structures is done to attract females. If females are impressed with a bower, she will choose the male that built it to mate. The better the nest is, the better the male genetic quality. So the female chooses this male because his genetic charge is significant and reflects a higher fitness for their progeny.
These bacteria rapidly divide until they run out of space. Their growth then slows down, and their population size stabilizes. What kind of curve would accurately show these changes in the population?
The correct answer is B. S-curve
Explanation
There are two models of population growth. One of them is the J-curve in which the population grows constantly without stabilizing, forming a J-shaped graph. Second, the S-curve is a model in which the population grows to a point, and from there it stabilizes, forming an S-shaped graph. According to the above, bacteria that divide rapidly until they run out of space and their growth slows down stabilizing the size of their population has an S curve model because the population does not grow unlimitedly but stabilized under specific circumstances. So, the correct answer is B. S-curve

Mutations in which of the following cells would get passed on to the next generation?
I. sperm
II. Skin cell
III. Egg
IV. Neuron
A. II, III, and IV
B. III only
C.I and III
D. I, III, and IV
Answer:
C. I and III
Explanation:
A mutation needs to occur in a gamete cell in order to be passed down to the next generation.
If it occurs in a somatic (body) cell, the mutation will only be present in that organism.
On the other hand, in a gamete cell, the mutation will pass down because gamete cells are directly involved in the genetic makeup of the offspring.
So, since sperm and egg cells are gametes, mutations in those cells would get passed on.
The correct answer is C. I and III

In Gregor Mendel's work with pea plants, he found that when a tall pea plant, with genes TT, was crossed with a short pea plant, with genes tt, that _____ % of the first generation of offspring plants were _____.
Answer:
In Gregor Mendel's work with pea plants, he found that when a tall pea plant, with genes TT, was crossed with a short pea plant, with genes tt, that _100_ % of the first generation of offspring plants were tall pea plant_.
Explanation:
After crossing the two types of plants, Mendel observed that among the F1 there were only tall variants, while the other variant (short) disappeared. Mendel named "dominant" the expressed variant. Mendel then let these new plants auto pollinate and observed the results in the second generation, F2. He saw that the short variant that had previously disappeared, reappeared again. Both tall and short plants were present in the F2. Mendel named "recessive" the second alternative variant.
Mendel explained his results by arguing that discrete factors were responsible for these phenotypes. These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors then separated again when sex cells were produced, giving two types of gametes, each with only one factor.
Mendel concluded that each plant had a pair of factors -which he named alleles-, and that each factor coded for one trait -tall and short-. He thought that these factors -T and t- separate -segregate- during gamete formation. This conclusion is known as the segregation principle (First Mendels´ Low).
Assuming that you observed similar patchy bacterial growth pattern in plates "B-Amp, phage" and "C-LB, phage". The T4 phages greatly affected the growth of E. coli strain CR63 in the LB plate ("C-LB, phage" plate), creating a patchy bacterial growth pattern similar to the expected result in the ampicillin plate of strain BE with phage ("B-Amp, phage" plate). Besides experimental errors, describe the possible reasons why the bacterial colonies were isolated in these two plates. "B-Amp, phage" Plate (strain BE)?
Answer:
Some bacterias show a great resistance power to fight against T4 phages That leads to great growth in the medium given that resistance power may be given by plasmids As plasmids show the resistant genes that great work in the medium.
T4 phage is a virus that shows a lytic cycle after affecting bacteria and going to kill the bacterial cells in bacterial strain So no growth in LB media. Some bacteria are sensitive due to the lack of resistant genes therefore, their growth may affect by many factors of the medium. If the bacteria are recombinant, they show greater growth in the medium.
* B-Amp, Phage plate (strain Be), there is ampicillin, so inhibits the growth of bacteria but still there is patchy growth of bacteria and they still show the growth but due to presence of phage T4, they show patchy growth.
