A. Nutrients and Oxygen. (The blood transports oxygen from the lungs to the cells of the body, where it is needed for metabolism. ... Blood also provides the cells with nutrients, transports hormones and removes waste products, which the liver, the kidneys or the intestine, for example, then get rid of.)

(b) Identify the dependent variable in the experiments. Identify a control group missing from the second experiment. Justify the
hammer [34]

Hello. You have not submitted the experiments to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.

A dependent variable is one that is influenced by an element, in order to present a result, that is, it is a variable that does not establish itself, being dependent on another variable to establish itself. An example of a dependent variable can be seen in an experiment that seeks to determine the differences in growth rates of bean plants that were fertilized with different organic fertilizers. As you can see, this is an experiment where the different organic fertilizers influence differences in the growth rate of bean plants. Thus, the growth of these plants depends on the fertilizer, this growth being the variable dependent on the experiment.

A control group, in turn, is an element of the experiment that does not receive the element that is being tested in the same experiment. The control group is important, because it allows the researcher to see the results of a system where the tested element does not exist, thus being able to determine the real differences that the tested element is capable of causing. Using the same example presented in the paragraph above, we can see that the different organic fertilizers are the elements tested in the experiment. These fertilizers will be applied to the plants, however it is important that at least one of these plants does not receive any fertilizer, so that the difference between a system with fertilizer and a system without fertilizer can be evaluated. This plant that received no fertilizer is the control group.

Alex_Xolod [135]

During a myocardial infarction, proteins that are normally inside the cells leak into the plasma, due to loss of plasma membrane integrity.

<h3>Cardiac disorders and it's effects:</h3>

There are different types of cardiac or heart disorders that occurs due to different etiological origins.

Example of a cardiac disorder is the myocardial infarction.

Myocardial infarction is defined as the blockage of blood flow to the heart by the presence of blood clot.

This hinders the delivery of oxygen carried by the blood to tissue cells leading to apoptosis (which is a programmed cell death).

This will cause the plasma membrane of cells to lose its integrity leading to leaking of proteins into the plasma.

DNA is composed of two strands, only one of which typically is used as a template for RNA synthesis. By what mechanism is the co
Andreyy89

To choose the strand the promoter acts to aim the RNA polymerase.

<h3>What does RNA polymerase do?</h3>

RNA polymerase synthesizes RNA by following a strand of DNA. The primary transcription enzyme is RNA polymerase. When RNA polymerase connects to a promoter sequence near the start of a gene, transcription starts (directly or through helper proteins). To create a fresh, complementary RNA molecule, RNA polymerase employs one of the DNA strands (the template strand) as a template.

Three distinct RNA polymerases (RNAPs), which transcribe various kinds of genes, are present in all eukaryotes. RNA polymerase I transcribe rRNA genes, RNA polymerase II transcribes mRNA, miRNA, snRNA, and snoRNA genes, and RNA polymerase III transcribes tRNA and 5S rRNA genes.

What 2 enzymes are used during DNA replication? describe what each does during replication
polet [3.4K]

The two enzymes that are used during DNA replication is helicase and polymerase. Each enzyme has distinct role that made it a vital part of the replication. In the course of DNA replication, the initial stage is to unzip the double helix structure of the DNA molecule by the enzyme helicase, which breaks the hydrogen bonds that holds the complementary bases of DNA.

Moreover, the DNA polymerase has the ability to exactly copy a DNA template. This enzyme binds to the leading strand and then adding a new complementary nucleotide bases to the DNA strand. In addition, it catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the increasing DNA chain.
