Why oxygen moves into the blood during alveolar gas exchange and out of the blood during systemic gas exchange.

Answer:

Pollution.

Explanation:

Human activities such as burning of fossil fuel increases the production of carbondioxide gas that leads to increase the temperature of the atmosphere as well as the ocean. The warm temperature of ocean causes bleaching of coral reef because the algae present on the coral reefs are removed which turn it into white or colorless corals.  The human activities such as pollution causes destruction of coral reef which leads to the destruction of habitat of  thousands of organisms and as a result loss of biodiversity occurs.

Answer: Dopamine

Explanation:

Drugs of abuse such as methamphetamine and morphine increase the levels of dopamine in the central nervous system. Dopamine has a variety of functions but functions mainly in motivation and reward mechanism. People doing drugs of abuse create a pleasurable sensation in which there is a dopamine surge every time they use drugs. In the absence of drugs, the body "looks" for the pleasure thereby causing the person to be drug-dependent and addicted.

Drugs of abuse that are commonly abused by people are alcohol, cocaine, MA, heroin, marijuana, nicotine.

Most of these drugs increase the level of dopamine in the brain.

Dopamine is an amine neurotransmitter which generates feelings of pleasure and thus creates a sense of euphoria.

Further, this neurotransmitter is also responsible for reward behavior and thus generates a feeling of satisfaction in the abuser.

Answer: D. Dopamine

Explanation:

Dopamine is the neurotransmitter that has been classically associated with the reinforcing effects of drugs of abuse and may have a key role in triggering the neurobiological changes associated with addiction.

To determine how many parts of dissolved minerals will be produced when 5000 ml of seawater evaporates, we need to calculate the amount of dissolved minerals in that volume. When 5000 ml of seawater evaporates, it will produce 175 parts per thousand (ppt) of dissolved minerals.

The average salinity of the ocean is 35 parts per thousand (ppt), which means that for every 1000 grams of seawater, there are 35 grams of dissolved minerals. To determine how many parts of dissolved minerals will be produced when 5000 ml of seawater evaporates, we need to calculate the amount of dissolved minerals in that volume.

Since 1 ml of seawater is equivalent to 1 gram, we have 5000 grams of seawater. To find the amount of dissolved minerals, we multiply the mass of seawater (5000 grams) by the salinity (35 ppt):

Dissolved minerals = 5000 grams * 35 ppt = 175,000 parts of dissolved minerals.

Therefore, when 5000 ml of seawater evaporates, it will produce 175 parts per thousand (ppt) of dissolved minerals.

True. Aristotle's philosophy proposed that all reality is composed of two fundamental principles: form and matter.

According to his theory, form refers to the essential characteristics or qualities that define an object, while matter represents the underlying substance or material that the object is made of. Aristotle believed that form and matter are inseparable and together constitute the essence of any entity in the natural world. This concept of form and matter had a significant influence on subsequent philosophical and scientific thought, particularly in the fields of metaphysics and biology.

The white blood cells that increase when there is an allergic reaction is basophil.

We have to note that the white blood cells are the cells that are responsible for fighting off the foreign bodies that try to make their way into the body. We have to note that once there is an invader that tries to enter into the body, there would be a resistance because the white blood cells would tend to prevent that kind of invasion. Generally, there are three kinds of blood cells and they are;

1) White blood cells

2) red blood cells

3) Blood Platelets

Each of these blood cells do have a unique role that each one of them does play in the body of a person.

Given that the white blood cells are the blood cells that are said to be involved when there is an allergic reaction, we now know that the particular part of the white blood cells that is responsible for the allergic reaction is the basophil.

A protein structure called a spindle fiber divides a cell's genetic material. In both mitosis and meiosis, two types of nuclear division, the spindle is required to divide the chromosomes in a mother cell into two daughter cells.

The microtubules, centrosomes, and associated structures that form during cell division, specifically in eukaryotic cells, are known as spindle fibers (those with a nucleus and membrane bound organelles). You'll see that spindle fibers are used as a collective phrase and incorporate some more specific language when we get into more detail about what these terms are and how spindle fibers are significant.

The correct answer is false. Insulin speeds up glucose transport across cell membranes and promotes glycogen synthesis and slows down glycogen breakdown.

Adipokines, proinflammatory substances, and free fatty acids are released by adipose tissue, an endocrine organ that affects both glucose and lipid metabolism. These substances reduce muscle ATP synthesis and glucose metabolism, encourage the synthesis of harmful lipid metabolites, and change insulin signaling. Insulin affects adipose tissue in two ways: 1) by increasing glucose absorption and triglyceride synthesis, and 2) by reducing triglyceride hydrolysis and the release of FFA and glycerol into the bloodstream. Elevated plasma FFA levels have been demonstrated to impair muscle insulin signaling, promote hepatic gluconeogenesis, and impair glucose-stimulated insulin response. Adipose tissue insulin resistance, which is the impaired suppression of lipolysis in the presence of high insulin levels, has been linked to glucose intolerance.

The part of the ventricle that is responsible for the last part of the QRS complex is A. endocardial surface of the apex of the left ventricle is depolarized last and thus is responsible for the last part of the QRS complex.

The QRS complex represents the depolarization of the ventricles during the cardiac cycle.

The depolarization wave spreads from the atrioventricular node (AV node) through the bundle of His and the bundle branches to the Purkinje fibers, which are responsible for rapid conduction of the depolarization wave to the ventricular myocardium.

During ventricular depolarization, the wave of depolarization spreads from the endocardial surface of the apex of the left ventricle towards the epicardial surface of the base of the ventricles.

The endocardial surface of the apex of the left ventricle is the last part of the ventricle to be depolarized.

As a result, the wave of depolarization spreads from the apex to the base of the ventricles, producing the characteristic QRS complex on the electrocardiogram (ECG).

Given the DNA sequence 5-TAC AAA ATA CAG CGG-3, these sequences represents a missense mutation is A) 5-TAC AAA ATA CAG AGG-3

A missense mutation is a type of mutation where a single nucleotide change in the DNA sequence results in a different amino acid being incorporated into the protein. To determine which of the given sequences represents a missense mutation, we need to compare each sequence to the original sequence (5-TAC AAA ATA CAG CGG-3) and identify the nucleotide change. A) The nucleotide change in this sequence is from CGG to AGG, resulting in the amino acid change from arginine to serine. Therefore, this sequence represents a missense mutation. B) The nucleotide change in this sequence is from AAA to AAG, but this does not result in a different amino acid being incorporated into the protein. Therefore, this sequence does not represent a missense mutation.

C) The nucleotide change in this sequence is from ATA to TAC, resulting in the same amino acid (tyrosine) being incorporated into the protein. Therefore, this sequence does not represent a missense mutation. D) The nucleotide change in this sequence is from TAC to TAG, which is a stop codon and would result in a truncated protein. Therefore, this sequence represents a nonsense mutation, not a missense mutation. E) The nucleotide change in this sequence is from CAG to CAC, resulting in the same amino acid (histidine) being incorporated into the protein. Therefore, this sequence does not represent a missense mutation. Therefore, the answer is A) 5-TAC AAA ATA CAG AGG-3, which represents a missense mutation.

The cycle of increased market demand that leads to overproduction and then a decline in market price has caused many firms bankruptcy.

The cycle described refers to a situation where there is a surge in market demand for a particular product or service. This increased demand prompts companies to produce more to meet the consumer needs. However, if the production exceeds the actual demand or if competitors flood the market with similar offerings, it can lead to overproduction. As a result, the market becomes saturated, causing prices to decline due to excess supply. This decline in market price can severely impact companies' profitability, potentially leading to financial struggles and even bankruptcy for some firms.

The average lifespan of a platelet in the peripheral circulation is around 8-10 days.

Platelets are one of the three main types of blood cells, along with red blood cells and white blood cells. They play a crucial role in the clotting process, helping to prevent bleeding and promote healing. Platelets are produced in the bone marrow and released into the bloodstream, where they circulate throughout the body.

While platelets have a relatively short lifespan, they are constantly being replaced by new platelets produced in the bone marrow. This ensures that there are always enough platelets in the bloodstream to help with clotting and healing. However, if there is a problem with platelet production or if platelets are being destroyed too quickly, it can lead to a condition called thrombocytopenia, which is characterized by low platelet counts and an increased risk of bleeding.
