What “drives” active transport and what “drives “ passive transport?
Answers
Answer:
Passive transport uses the kinetic energy and natural entropy of molecules moving down a gradient. While active transport uses cellular energy to move against a gradient.
Answer:
The second law of thermodynamics
Explanation:
Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. Instead of using cellular energy, like active transport, passive transport relies on the second law of thermodynamics to drive the movement of substances across cell membranes.
Which of the following pairs of base sequences could form a short stretch of a normal double helix of DNA?
(A) 5′-AGCT-3′ with 5′-TCGA-3′
(B) 5′-GCGC-3′ with 5′-TATA-3′
(C) 5′-ATGC-3′ with 5′-GCAT-3′
(D) All of these pairs are correct
Answers
Answer:
The correct option is C
Explanation:
First of all, we need to know that a DNA molecule can have the following bases; Adenine (A), Thymine (T), Guanine (G) and cytosine (C). These bases have the ability to bind to each other on complementary strands in the following way; adenine can only bind to thymine and vice versa while guanine can only bind to cytosine and vice versa.
It also be noted that when one strand of the DNA runs from 5' to 3', the complementary strand runs from 3' to 5', hence they run anti-parallel to each other.
So, the only option sequence that meets the criteria discussed above is option C,
5'-ATGC-3'
3'-TACG-5'
The illustration above shows how the bases will be on the complimentary strands when they run anti-parallel to each other. And they can also be written as 5′-ATGC-3′ (this is read the way it is written) and 5′-GCAT-3′ (this is read from the back as in from 3' to 5')

As a skeletal muscle continues to contract, the amount of ATP available is _____, leading to weakening contractions, a phenomenon called muscle fatigue.
Answers
As a skeletal muscle continues to contract, the amount of ATP available is reduced, leading to weakening contractions, a phenomenon called muscle fatigue.
Does excess ATP cause muscle fatigue?In contrast, as soon as the exercise intensity exceeds the ATP synthesis rates of oxidative phosphorylation requiring an increased reliance on anaerobic metabolism, force and power become impaired, fatigue develops, and failure to sustain the exercise occurs within seconds to minutes of the onset of contractile activity.There are two main causes of muscle fatigue: the limitations of a nerve's ability to generate a sustained signal (neural fatigue); and the reduced ability of the muscle fiber to contract (metabolic fatigue).Learn more about muscle fatigue here: brainly.com/question/28179328

What corrective options are available to the surgical team members when a breach in sterile technique
Answers
When a breach in sterile technique is noticed, the surgical team members have several corrective options that they can consider to minimize any negative consequences. These corrective options include:
Disclosing the breach: If the breach is minor, it is important that the surgical team members disclose the breach to everyone involved in the procedure as soon as possible. This will allow everyone to take appropriate action to prevent any infections from occurring.
Correcting the breach: Once the breach has been disclosed, the surgical team members should work to correct the breach as soon as possible. For example, if a surgical instrument was dropped on the floor, it should be removed from the surgical field and replaced with a sterile instrument to minimize the risk of infection.
Restarting the procedure: In some cases, it may be necessary to restart the entire procedure if the breach is too significant to be corrected. While this may be time-consuming and may delay the procedure, it is important to prioritize the safety of the patient above all else.
Documenting the breach: Finally, the surgical team members should document the breach in detail. This documentation should include the type of breach that occurred, when it occurred, and what corrective actions were taken to address the breach.
This information can be used to help prevent future breaches and to identify areas for improvement in the surgical process.

77. Allergies, such as those caused by pollen, occur when a specific type of immune cell recognizes that pollen is as a(n) for which to create antibodies.
Answers
Allergies, such as those caused by pollen, occur when a specific type of immune cell recognizes that pollen is an allergen for which to create antibodies.
A substance that can trigger an allergic reaction is known as an allergen. The immune system of some individuals perceives allergens as threatening. In order to protect itself from the allergen, the immune system responds by producing a particular form of antibody known as IgE. Allergy symptoms result from this response.
The immune system's defense mechanisms include keeping harmful bacteria, viruses, and fungi out of the body and eradicating any infectious microbes that do get inside.
Allergens can enter the body through the skin, mouth, or respiratory system. Immunoglobulin E (IgE) is a kind of antibody generated by the body that has been related to common allergic reactions such as fever, some types of asthma, and hives. Each IgE antibody can respond quite specifically to particular allergens and pollens.
The immune system recognizes pollen as an allergen or intruder if someone has a pollen allergy. Immunoglobulin E (IgE) produces antibodies when the immune system overreacts.
Hence, the correct answer is an allergen.

Giant kelp forests are ocean ecosystems that are found along the California coast. This food chain shows one of the feeding relationships in giant kelp forests. Make a claim about how a decrease in the population size of California sea otters will most likely affect the population size of the giant kelp and provide reasoning to support your claim.
Answers
If the population size of sea otters decreases, then the population of the giant kelp will also decrease. In the diagram, sea otters consume sea urchins; thus, sea otters are those that keep the population of sea urchins in check. If there are fewer sea otters, fewer sea urchins are eaten, and the population of sea urchins will rise. In the diagram, the sea urchins consume giant kelp. Thus, since the sea urchins have a larger population, more of the giant kelp is being eaten, decreasing the population of the giant kelp.
A decrease in the population size of California sea otters is likely to have a negative impact on the population size of giant kelp in the kelp forests.
What is the role of California sea otters?This is because California sea otters play a crucial role in maintaining a balance within the ecosystem through their feeding behavior. Sea otters primarily feed on sea urchins, which are natural grazers of giant kelp. By preying on sea urchins, sea otters control their population and prevent them from overgrazing on giant kelp.
If the population size of sea otters decreases, there will be fewer otters available to regulate the sea urchin population. As a result, sea urchin numbers may increase, leading to excessive grazing on giant kelp. Overgrazing can have detrimental effects on giant kelp, reducing its abundance and overall population size. Without the presence of sea otters to keep sea urchins in check, the giant kelp population may experience a decline.
Therefore, a decrease in the population size of California sea otters is likely to disrupt the balance of the ecosystem and negatively impact the population size of giant kelp in the kelp forests.
