Once the fragments are formed, DNA ligase joins them together to form a single, continuous strand.

After replication, the Okazaki fragments must be joined together to form a single continuous strand. This is achieved by the enzyme DNA ligase, which closes the Okazaki fragments' sugar phosphate backbone. This enables the replication of two identical daughter strands of DNA.

As the helix unwinds, DNA synthesis on the lagging strand restarts multiple times, resulting in many small pieces known as "Okazaki fragments." The Okazaki fragments are joined together into a single DNA molecule by DNA ligase.

The activity of DNA ligase joins these little chunks of newly produced DNA (dubbed Okazaki fragments after their discoverer) to generate an entire new DNA strand.

Explanation:

The proper order of structures that contact the substances removed from the blood is: c. nephron → ureter → bladder → urethra. Therefore, the correct option is c.

The nephron is a functional unit of the kidney that filters the blood and removes waste products. The ureter is a tube that carries urine from the kidney to the bladder.

The bladder is a muscular organ that stores urine until it is released from the body through the urethra. Finally, the urethra is a tube that carries urine out of the body.

The part of the kidney responsible for filtering blood and producing urine is called a nephron. The ureter, a muscular tube that transports urine from the kidney to the bladder, receives the pee next.

The urethra, a tube that extends from the bladder to the outside of the body, is where urine is expelled. The bladder is a muscular sac that holds urine until that time. Therefore, the correct option is c.

Mendel prevented self-pollination by the pea plants by removing the pollen-bearing part of the plant.

Mendel conducted several plant breeding experiments to study how traits are inherited in living organisms using the pea plant.

In some of the experiments, he needed the plant not to self-fertilize. Thus, he decided to remove the polling-bearing part of such plants.

The pollen-bearing part of a plant is known as the anther. By doing so, the male gamete, which is the pollen, will not be available to fertilize the female gamete of the same plant.

In the brachial plexus the posterior cord contains portions of C5 nerves.

Here, correct option is C.

The posterior cord of the brachial plexus contains portions of nerves C5 through T1. The posterior cord is a bundle of nerve fibers that arise from the anterior rami of the lower four cervical nerves (C5-C8) and the first thoracic nerve (T1).

These nerves provide motor innervation to the posterior muscle groups of the upper limb, including the triceps, deltoid, supraspinatus, infraspinatus, teres minor, and subscapularis. In addition, the posterior cord provides sensory innervation to the skin on the posterior aspect of the arm, as well as to the shoulder joint.

The posterior cord also contains fibers that travel to the brachial artery, supplying motor innervation to the vessels and muscles in the arm. As such, the posterior cord plays an important role in the proper functioning of the upper limb, providing motor, sensory and vascular innervation to the structures of the arm.

Therefore, correct option is C.

The statement that the nurse knows is true regarding a grade 2 goiter is: A grade 2 goiter is palpable and visible when the neck is in a normal position.

Classification of goiter by palpation:

Grade 0: no goiter is palpable or visible. Grade 1: palpable goiter, not visible when neck is held in normal position. Grade 2: a clearly swollen neck (also visible in normal position of the neck) that is consistent with a goiter on palpation.

A grade 2 goiter, also known as a "moderate" or "noticeable" goiter, is characterized by an enlargement of the thyroid gland that is both palpable, meaning it can be felt by touch, and visible when the neck is in a normal position.

This is in contrast to a grade 1 goiter, which is only palpable but not visible, and a grade 3 goiter, which is even larger and more visibly prominent.

The Ions that contribute to the resting neuronal membrane potential include potassium ion.

Ions are any atoms or clusters of atoms with an electric charge. Positively charged ions are referred to as cations. Ions with a negative charge are known as anion.

The amount that an ion will alter the membrane potential of a cell depends on its capacity to carry electricity. The three primary conductances that determine the resting membrane potential are chloride, potassium, and sodium.

Cations are the name for positive-charged ions. Anions are the name for ions that have a negative charge.  Sodium, potassium, calcium, chloride, and bicarbonate are typical examples.

Answer:

In the "Mystery of the Buffalo boom" scientists first try to find the answer in the two most common things that can affect a population of animals.  Food and predators.

First, they studied the buffalos' food supply, grass. They found that there has not been an increase in it so that the number of buffalos multiplied.

Then they studied the predator's population, and they found that there was not a decrease in the number of them that could affect the buffalos increasing numbers.

As the two main things that controlled a population were not affected, they had to find other causes. The next thing that they studied were historical facts about buffalos and diseases. Scientists discovered that a virus that affected cows had impacted these animals too, which was the cause of a considerable decrease in the buffalo's population many years back.

Due to the drastic impact that the rinderpest had on cows, a vaccination plan was implemented. As the cows now were protected against this virus, the virus could not reproduce as it did, ending the spreading of this disease in cows. As a consequence, the buffalos were no longer infected, and their population grew thanks to the vaccination plan.

In conclusion, when the most common things that can affect a population are not the cause, we have to look into the past and find what has changed and how it impacted the animals. It is using logical thinking skills to determine what has changed and what that change made.

Explanation:

In the video "Mystery of the Buffalo boom" the ecologist Tony Sinclair found an abnormal buffalos' number in Tanzania. As the increase in the buffalos' population was something unusual, he knew that something had changed, but he did not know what. Sinclair, with other scientists, used their reasoning skills and thought that the two most logical things that can affect a population are food and predators. When they studied these two variables, they found out that they were not the problem. The next step was to look for past events that impacted buffalos. They found out that a virus, which directly affected cows but also buffalos, had been erased from the Earth thanks to a vaccination plan. As a result, the disease spreading between cows stopped, and as a consequence, it also stopped between buffalos.

We can see that everything is connected and that by using reasoning skills and logic, scientists could determine what happened.

Monoclonal antibodies are used in pregnancy test kits. These are made to bind with a hormone called HCG, which is only present in pregnant women's urine.

Three different types of antibodies, two from mice and one from a goat, are used in home pregnancy tests. The test strip's papery substance contains the initial antibody molecules (where the urine sample is applied).

The primary methods for detecting human chorionic gonadotropin hormone have mostly been supplanted by the conventional immunoassay, which is based on the classic antigen-antibody reaction (HCG).

Antibodies are used in home pregnancy tests to look for the Human Chorionic Gonadotropin hormone, which can be detected in urine at levels that indicate pregnancy. The test strip has two antibodies that "sandwich" together to capture the HCG antigen.
