The structure-function pair is which was mismatched from the task above is microtubule; muscle contraction.
The correct answer choice is option a.
What is microtubule mismatched with the function of muscle contraction?The simple reason why microtubule is wrongly mismatched with the function of muscle contraction simply is that the microtubules help to support cell division and protection to cell shape. That being said, cell structures which are found within the cytoplasm are known as cytoplasmic organelles.

What are the four steps in the transcription process?The process of copying DNA to create a complementary strand of RNA is called transcription. After that, RNA is translated to become proteins. Initiation, promoter removal, elongation, and termination are the four main phases of transcription.
In what transcription does the nucleus engage?Transcription takes place in the cell's nucleus since the genes are bound there, but the mRNA transcript needs to be delivered to the cytoplasm. In prokaryotes, which include bacteria and archaea, transcription takes place in the cytoplasm of the cell since these organisms lack organelles and membrane-bound nuclei.

Explanation:
many people believe that taking zinc lozenges reduces the severity and duration of the common cold. sebastien decides to conduct a study at his school to explore this claim. he sends a survey to a simple random sample of 100 students, asking them to if they took zinc lozenges or not during their last cold, and how long they experienced cold symptoms. he found that students who took zinc had a mean cold duration that was 1.2 days lower than those who did not take zinc. which of the following statements about his study is true?
Sebastien's study is subject to confounding.
What are zinc lozenges?
A well-liked remedy for the common cold is zinc. According to some studies, zinc lozenges may shorten colds' duration by one or two days and may lessen the incidence of upper respiratory infections. Zinc aids in wound healing and infection prevention. Treatment of the common cold with zinc gluconate lozenges, using adequate doses of elemental zinc, may be effective in reducing the duration and severity of cold symptoms. If the lozenges are started as soon as symptoms appear, the benefit seems to be at its greatest. The formulation of the lozenges also appears to be important because the addition of citric acid or tartaric acid may reduce efficacy due to the chelation of zinc ions.

The radial, musculocutaneous, median, ulnar, and axillary nerves are the brachial plexus' five terminal branches.
Note that the network of nerves called the brachial plexus is what carries signals from the spinal cord to the shoulder, arm, and hand. A brachial plexus injury happens when these nerves are compressed, stretched, or in the most severe scenarios, torn apart or severed from the spinal cord.

Prezygotic and Postzygotic barriers are reproductive isolation mechanisms, which avoid mating events or prevent viable and fertile mixtures between different species. Pre-zygotic barriers: One bird species prefers open areas, whereas another bird species prefers wooded areas. One frog species mates in the spring, whereas another frog species mates in the summer. Postzygotic barrier: A horse and donkey mate to produce a sterile mule. Individuals from two different species mate, but the resulting embryo dies before birth.

A beneficial mutation is one that has a good effect on an organism. These mutations are uncommon yet important. The benefit that a beneficial mutation provides the organism is passed down from generation to generation, increasing the chances of survival for the offspring.
Neutral mutations:
Neutral mutations are changes in DNA sequence that are neither beneficial nor harmful to an organism's ability to survive and reproduce. In population genetics, neutral mutations are mutations in which natural selection has no effect on the spread of the mutation in a species.
Harmful mutations: Mutations that are harmful can result in genetic diseases or cancer. A genetic condition is an illness that results from a mutation in one or more genes. Cystic fibrosis is a human example. A single gene mutation causes the body to produce thick, sticky mucus, which clogs the lungs and blocks ducts in digestive organs.

The human reproductive system occurs through the fertilization process, namely the meeting of male gametes and female gametes. The fertilization process will produce a zygote, the zygote then undergoes embryonic development until it is born as a child.
The fertilization process begins with the maturation of the egg and spermatozoa. During ovulation, the spermatozoa penetrate the corona radiata until the sperm attaches to the zona pellucida. When the spermatozoa successfully penetrate the zona pellucida, oocyte fusion will occur. Haploid sperm cell to fertilize the haploid egg.

In this project, you will design, evaluate, and refine a device that minimizes the force
on an object during a collision. You should apply scientific ideas to develop your
device and try to avoid unanticipated effects. Apply the law of conservation of linear
momentum to the situation in which your device should be used, and compare the
velocities and momenta of objects in the system. Note that the total momentum of a
system can change, but the change is balanced by the momenta of objects outside
the system. In your design, you should specify any criteria and constraints, such as
limiting risk. You should be able to quantify how your design satisfies these criteria
and constraints. You may have to break down complex criteria into simpler ones and
prioritize certain criteria over others.

An object's momentum is based on the mass and velocity of the object. The more
momentum the object has, the harder it is to stop the object or change its direction.
