Jerome also had blood work done to confirm the MI. The presence of troponin, or cardiac enzymes such as CK-MB, are a positive indicator of an MI. Why is their presence at higher levels in the blood indicative of an MI?a. They are by-products of aerobic metabolism and if they are present in higher amounts in the blood it shows that the myocardium is working harder.
b. They are substrates for aerobic metabolism and if increased in the blood show that the cardiac muscle is not functioning normally.
c. These proteins are normally found inside cardiac muscle cells and if present in the blood indicate damage to the cells.
d. They are by-products of anaerobic metabolism (glycolysis) and if increased indicate that the heart is not receiving oxygen.

Answer 1

Answer:

Answer:

c.These proteins are normally found inside cardiac muscle cells and if present in the blood indicate damage to the cells.

Explanation:

When there is a decreased blood flow to the heart or if a particular part of the heart stops working then this is known as myocardial infarction (MI) and due to this the heart muscle gets damaged.

There are several biomarkers that are used to evaluate the functioning of the heart and these are known as cardiac markers, an example of this is Ck-MB which is an isoform of creatine kinase.

The CK-MB isoform is found in the cytosol of the heart muscle cells and it plays a role in causing the movement of high energy phosphates in and out of the mitochondria.

If there is a damage to the heart muscle cells which usually occurs following a myocardial infarction CK-MB levels elevates in the blood for a short period of time and this indicates MI.

Fishermen have harvested certain fish to the point where the population of that fish is decreasing. This level of direct harvesting could cause (1) ecosystems to be improved for future generations (2) ecosystems to be severely damaged (3) the restoration of environmental stability (4) all other fish species to increase in number

Answers

This level of direct harvesting could cause the ecosystems to be severely damaged. The correct option among all the options that are given in the question is the second option or option "B". This type of fishing can disturb the natural balance and ultimately several species might vanish from our earth.

The different forms of a gene are called __________a. alleles.
b. factors.
c. masks.
d. traits.

Answers

Alleles

Each human body is composed of genes, and these usually come in pairs that are slightly different from each other. The different versions of genes are called alleles. Alleles are responsible for determining physical or notable characteristics and traits a specific person has.

Final answer:

The different forms of a gene are called alleles. These are different versions of the same gene that are located at the same position on a chromosome. Terms like factors, masks, and traits are not used to describe this concept in biology.

Explanation:

The different forms of a gene are called alleles. In biology, alleles refer to the different versions of the same gene, which are located at the same position, or genetic locus, on a chromosome. For example, in humans, the gene for eye color has an allele for blue eyes and another for brown. Factors, masks, and traits are not accurate terms for this concept. Factors typically refer to different elements or components that contribute to a particular outcome. Masks might be used in the context of genetics to refer to the concealment of a trait by the presence of another trait. Lastly, traits are the characteristics or features that are expressed by an organism, as a result of its genetic makeup.

Why are environmentalists concerned about the introduction of genetically engineered trees?

Answers

Environmentalists are concerned about the introduction of genetically engineered trees because genetically engineered trees decrease the biodiversity that is present in the natural ecosystem. environmentalists are concerned that this can lead to the eradication of several variety of plants.

Answer: The environmentalists are concerned about the introduction of genetically engineered trees because their introduction into the environment could have unexpected interactions with the other plants and animals present in the ecosystem.

Other reason can be loss of native species. The native species that is originally present in the environment can be lost due to the introduction of genetically engineered plant species.
