Answer:
Fats would accumulate in the liver and the individual would show hypocholesterolemia
Explanation:
Familial hypercholesterolemia is a genetic disorder caused by a reduction and/or defect in the low-density lipoprotein (LDL) receptor. Moreover, apolipoprotein B is the unique protein component of LDL, which plays a critical role in lipid metabolism by binding the LDL receptor. Familial defective apolipoprotein B-100 refers to an inherited disorder associated with mutations of the apolipoprotein B-100 that leads to moderate or severe cases of hypercholesterolemia. Mutations in apolipoprotein B-100 are associated with a reduction in the binding capacity of LDL to the LDL receptor, thereby leading to hypercholesterolemia.
A man is brachydactylous (very short fingers; rare autosomal dominant), and his wife is not. Both can taste the chemical phenylthiocarbamide (autosomal dominant; common allele), but their mothers could not. Give the genotypes of the couple. If the genes assort independently and the couple has four children, what is the probability of all of them being brachydactylous
Answer:
The correct answer is -
A) BbTt x bbTt
B) .5^4 or 1/16 or 0.0625
Explanation:
As it is given that Brachydactylus and PTC tasters both traits are autosomal dominant conditions which mean only one allele would be enough.
For Branchydactylus and For tasting : man and women will be heterogeneous.
Hence,
The Genotype of man = BbTt
The Genotype of wife = bbTt
b. Answer = 0.0625
For Branchydactylus:
Bb X bb
Possible genotypes:
B b
b Bb( Brachydactylus) bb(normal)
b Bb (Brachydactylus) bb (normal)
The probability of a single child being Branchydactylus = 2/4 = 0.5
So, Probability of all 4 child being Branchydactylus = .5 x .5 x .5 x .5 = 0.0625

B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides. C) A polysaccharide consisting of 3 types of monosaccharide units and cross-linking oligopeptides. D) Two different polysaccharides and 1 type of oligopeptide, which are cross-linked.
Answer:
B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
Also, a unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
A bacterial cell is made up of peptidoglycan and its main function is to maintain the shape of a cell while preventing it from bursting due to osmotic pressure. Also, the bacterial cell inhibits the passage of larger molecules but allows the free movement (passage) of smaller molecules in the body of a living organism.
Basically, bacterial cell wall comprises a polysaccharide that's typically made up of two (2) types of monosaccharide units and cross-linking oligopeptides.

According to the ESRT, the rate of temperature increases below the Earth's surface is greatest between depths of
Answer:
Between depths of tectonic plate boundaries and the outer core.
Explanation:
The rate of temperature increases below the Earth's surface is greatest between depths of tectonic plate boundaries and the outer core. At the depth, some of the heat comes from the Earth's core while most of the heat comes from decay of radioactive elements, mainly uranium, thorium and potassium that is located in rocks of the crust. So we can say that the the increase in temperature with depth varies with the chemical composition and age of the rocks.

What is food web?A food web is a diagram that depicts the interconnection of various organisms in an ecosystem via the exchange of energy and nutrients.
The food web is made up of several interconnected food chains that represent the flow of energy from one organism to the next.
Fungi are decomposers that play an important role in breaking down organic matter and recycling nutrients in many ecosystems.
The fungus in the food web is most likely breaking down dead plant or animal matter, releasing nutrients like carbon, nitrogen, and phosphorus back into the soil.
These nutrients are then absorbed by plants, which are then consumed by herbivores such as the coati and sloth.
Thus, the correct option is A.

As more is learned about cancer, it has become clear that cancer, with few exceptions, ________. Group of answer choices is only dependent on the inherited genetics is a result of genetics and environmental factors is 100% dependent on inherited genetics has no genetic basis
Answer: Is a result of genetics and environmental factors.
Explanation:
Cancer is the common name for a group of diseases in which there is a division of the body's cells, whose growth exceeds that of normal tissues and which persists in the same excessive manner. It can begin in a localized manner and spread to other surrounding tissues and its malignancy is very variable, according to the aggressiveness of its cells and other biological characteristics of each type of tumor. In general, the behavior of cancer cells is characterized by lacking the reproductive control required by their original function, acquiring the capacity to invade tissues (metastasis), spreading through the organism via the lymphatic or circulatory system, and causing the growth of new tumors in other parts of the body.
A gene is a hereditary unit composed of DNA that carries the instructions for producing proteins, which do much of the work in our cells. Certain genetic alterations can cause cells to evade growth controls and become cancerous cells. These changes can be inherited from our parents if the changes are present in the germ cells (eggs and sperm) and they are called germline changes. In addition, cancer-causing genetic changes can also be acquired during a person's lifetime (somatic or acquired changes), as a result of DNA errors that occur when cells divide either spontaneously or by exposure to carcinogenic substances that damage DNA (environmental factors), such as certain chemicals in tobacco smoke, or radiation, such as ultraviolet rays from the sun. These substances damage DNA, acting as mutagens.
Sometimes, the changes are not in the DNA sequence. For example, the epigenetic modifications are the presence of chemical marks in DNA which can determine if the gene is expressed. This means, whether and how much messenger RNA is produced, because the messenger RNA is translated into proteins.
So, cancer cells have genetic changes compared to normal cells. These changes are due to mutations that can be inherited, acquired spontaneously during life, or acquired due to environmental factors such as sun exposure, smoking, and other factors. In addition, the fact that a person has the cancer-related mutation does not necessarily mean that he or she will develop the disease during his or her lifetime. In some cases, even if they have this genetic vulnerability, they remain healthy, because cancer is a multifactorial disease that depends on many factors, such as the immune system, nutrition and certainly many others currently unknown to medicine.
