A common genetic mutation that lowers levels of the enzyme cathepsin C severely reduces a person’s ability to ward off periodontitis, or gum disease. The enzyme triggers immunological reactions that destroy diseased cells and eliminate infections
in the mouth. But researchers are developing ways to restore the enzyme to normal levels. Once that happens, we will be able to eliminate periodontitis.
Which one of the following is an assumption on which the argument depends?
(A) Restoring cathepsin C to normal levels is the only way to eliminate periodontitis.
(B) Genetic mutation is the only cause of lowered levels of cathepsin C.
(C) Researchers will soon succeed in finding means of restoring cathepsin C to normal levels.
(D) Persons who do not have the genetic mutation that lowers levels of cathepsin C do not get gum disease.
(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.

Answers

Answer:

(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.

Explanation:

Considering the fact that there may be some other causes of periodontitis aside from the lowered levels of the enzyme.

Therefore, should there be some other causes of periodontitis, hence, it can be concluded the process of restoring the enzyme to normal levels might not be sufficient for eliminating periodontitis.

Hence, the author's argument is solely based on this assumption, and option. Hence, option (E) is the correct answer.

All of the following are evidence for the big bang except: A. Cosmic background radiation B. Almost all galaxies are red-shifted C. The sound from the bang echoes though the universe D. The universe is expanding

Answers

Answer: C. The sound from the bang echoes though the universe

Explanation:

Cosmic background radiation proves the big bang because it shows that as a result of the big bang, the early universe was really hot but cooled as it expanded. Cosmic background radiation is the result of that earlier heat.

Galaxies being red-shifted means that the space between galaxies is increasing which means that the universe is expanding which provides evidence for a big bang because particles move away the single point they are concentrated in.

There was no actual bang from the big bang and sound cannot echo through space so c is incorrect.

Answers

Answer:

cannot be synthesized in the body in sufficient quantity to meet body needs.  

Explanation:

Amino acids are defined as the structural units which make up the proteins in our bodies. They help to break down foods, repair tissues, and serves many more functions.

Most fresh water fish are hypertonic, meaning their body cells contain more salt than the surrounding water. Since osmosis should push water into their cells, why don't they explode? They don'­t drink any water because they get so much from osmosis. They have adapted to live with high osmotic pressure. They urinate a lot, so the water does not build up. Their cells have adapted to absorb salt. All of the above

Answers

Answer:

They urinate a lot, so the water does not build up.

Explanation:

Freshwater fishes are fishes that live in freshwater habitat i.e. little or no salt. This means that the fishes are hypertonic (have more salt) to their external environment. Due to their hypertonicity, freshwater fishes tend to take in more water via osmosis.

Freshwater fishes, however, do not explode despite this phenomenon because they pass out the excess water via urine waste. Freshwater fishes urinate a lot, hence, the absorbed water does not build up in their bodies.

Answers

Answer:

is expressed roughly equally in both sporulating and nonsporulating yeast

Explanation:

A DNA microarray (also called DNA chip) is a microchip-based testing platform which can be used to analyze and compare gene expression profiles between samples. A DNA microarray contains microscopic DNA spots attached to a solid surface, where each spot corresponds to thousands of copies of a specific DNA sequence (i.e., probes). Subsequently, cDNA 'target' molecules obtained by reverse transcription from RNA are then hybridized to a microarray. This process of hybridization can be quantified by using fluorophore-labeled targets that determine the level of the expressed gene (transcript) in the target sample. In a DNA microarray, the intensity and types of color in each spot indicate the presence and level of each specific transcribed gene in the samples. In consequence, the presence of yellow spots in the DNA microarray indicates approximately equal expression levels of the corresponding gene in both yeast samples.

Which type of white blood cell is activated by antigens that are bound to antibodies?
monocytes
eosinophils
basophils
neutrophils

Answers

Answer:

basophils

Explanation:

Basophils are a class of white blood cells known as granulocyte, which also include neutrophils, eosinophils, and mast cells. These cells (basophils) are generated in the bone marrow as other white blood cells. When stimulated, basophils degranulate to release histamine, proteoglycans, and proteolytic enzymes and thus mediate immune responses. This process of degranulation occurs when a specific antigen binds to the IgE receptor on the basophil. Moreover, basophils may also be activated by inflammatory mediators (e.g., complement factors such as C5a and C3a, chemokines, etc).

Answers

Answer:

B Edge 2021

Explanation:

I just took the test

When a sperm fertilizes an egg, the fertilized egg, also known as a zygote, will travel from the fallopian tube to the uterus, where it will implant and grow into a fetus. Therefore, the correct option is B.

What is a fertilized egg?

A fertilized egg is also known as a zygote. It is a single cell that results from the union of a sperm and an egg during fertilization. Fertilization typically occurs in the fallopian tube of a female reproductive system when a sperm successfully penetrates and merges with the egg.

The egg is released from the ovary and travels through the fallopian tubes towards the uterus. It is in the fallopian tubes where the egg can be fertilized by a sperm, forming a zygote.

The zygote will then continue to travel through the fallopian tube towards the uterus. As it approaches the uterus, the zygote will undergo several cell divisions, forming a ball of cells known as a blastocyst.

The blastocyst will then implant into the lining of the uterus, where it will continue to grow and develop into a fetus. The cervix, which is the lower part of the uterus, plays a role in pregnancy by keeping the fetus inside the uterus during gestation and then opening to allow for delivery during childbirth.

Therefore, option B) the fallopian tubes and uterus is correct.

c. the movement of the flagella of sperm for motility
d. exocytosis of waste substances across a semi-permeable membrane

Answers

Answer:

b. diffusion and osmosis across semi-permeable membranes

Explanation:

ATP (adenosine triphosphate) is a high energy carrying molecule in the system of living organisms. It posseses the ability to store and release energy for use by organisms during biochemical activities. However, some processes do not require ATP to occur and are called PASSIVE TRANSPORT while those that require energy (ATP) are called ACTIVE TRANSPORT.

In the above options, the processes listed as follows require ATP to occur:

- The active transport of glucose from the small intestine to the blood

- The movement of the flagella of sperm for motility

- Exocytosis of waste substances across a semi-permeable membrane

However, the diffusion and osmosis across semi-permeable membranes, which is a passive transport does not require ATP.

An individual with two different versions of a gene is genetically ____________ . In traits with a simple pattern of inheritance, only the trait conferred by the ____________ form of the gene will be visible. The other form of the gene is ____________ : it confers a trait that is only visible when the individual is genetically ____________ , or has two identical copies of the gene.

Answers

Answer:

heterozygous; dominant; recessive; h.o.mo-zygous

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

In Genetics, co-dominance can be defined as a phenomenon in which two (2) alleles of the same gene are present in a living organism and both are equally expressed to a degree or simultaneously.

This ultimately implies that, co-dominance is a phenomenon that typically involves the relationship between alleles i.e the two (2) versions of a gene present in living organisms. Also, a single version of a gene expressed by a living organism is referred to as an allele.

Trait can be defined as a distinguishing quality or characteristic of a living thing.

Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.

Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.

In Genetics, when an individual has two (2) different versions of a gene, he or she is said to be genetically heterozygous.

In traits with a simple pattern of inheritance, only the trait conferred by the dominant form of the gene from the parent organism will be visible in the offspring of a living organism. The other form of the gene is recessive : it confers a trait that is only visible when the individual is genetically , or has two identical copies of the gene.
