On a warm day near the ocean, a breeze or wind often blows from the water to the land. Explain why this happens

Answers

Answer:

It occurs because of the difference in temperature between the ocean and the land.  

This happens because the land heats up faster than the water, causing the air to rise above the land and allowing cooler air from the ocean to move in and take its place.

What is sea breeze?

Because land and water have different capacities for holding heat, the land will heat up more quickly than the water on a hot day near the ocean. As a direct consequence of this, the air that floats above land tends to become warmer and less dense than the air that floats above water. Because of this, a region of low pressure is created over the land, while a region of high pressure is created over the water. In order to maintain a natural equilibrium, air will always move from areas of higher pressure to areas of lower pressure.

A breeze or wind that blows from the water to the land is caused by the air that is cooler and denser over the water moving towards the air that is warmer and less dense over the land. This phenomenon, which is referred to as a sea breeze, can assist in moderating temperatures on land, thereby making it feel more bearable and pleasant to be there.

How does actin and myosin work together to help you lift an object?

Answers

Answer:

Muscle contraction thus results from an interaction between the actin and myosin filaments that generates their movement relative to one another.

Actin and myosin work together to help you lift an object in the following way:

Muscles are tissues of the musculoskeletal system that have the function of generating a force towards the bones with the ultimate goal of performing a movement.

In order for this function to be carried out correctly, it needs proteins that are found inside the muscle fiber, these proteins are myosin and actin.

The myosin head in the presence of ATP binds with the actin filaments, in order to generate a minimum slip that later becomes a coordinated and precise movement as lift an object.

That is, myosin binds to the actin protein to generate the contraction of the muscles, and therefore the movements we make with our extremities.

Therefore, we can conclude that actin is a cellular protein in muscles that is involved in muscle contraction when it connects with myosin.

Which of the following statements best explains the structure and importance of plasmids to prokaryotes?
Plasmids are circular, single-stranded RNA molecules that transfer Information from the prokaryotic chromosome to the ribosomes during protein synthesis.
B
Plasmids are circular, double-stranded DNA molecules that provide genes that may aid in survival of the prokaryotic cell.
с
Plasmids are single-stranded DNA molecules, which are replicated from the prokaryotic chromosome, that prevent viral reproduction within the prokaryotic cell.
D
Plasmids are double-stranded RNA molecules that are transmitted by conjugation that enable other prokaryotic cells
acquire useful genes.

Answers

Answer:

B  Plasmids are circular, double-stranded DNA molecules that provide genes that may aid in survival of the prokaryotic cell.

Explanation:

Plasmids would be additional chromosomal, double stranded also it is covalently that are closed and circular DNA molecules. It possesses genes that represent some unique attributes to the prokaryotic cell like fertility factor, F plasmid, etc. It may existed as an independent entity that should be within the cell or may be they integrate within the host genome this we called as an episomal in nature

In addition to this, Plasmids plays a significant role in the gene transfer i.e. horizontal that should be within the prokaryotes and are widely used in the recombinant DNA technology like vectors

Therefore, the option b is correct

Plasmids are the extrachromosomal material present in prokaryotic cells that divides independently. They are circular and aids in the survival of prokaryotic organisms.

What are plasmids?

Plasmids are the extra genetic material that is double-stranded and circular found along with the nucleoid in the cytoplasm of the prokaryotic cell. They are majorly used in the genetic engineering process.

They provide protection and antibiotic resistance in the prokaryotes like bacteria as they carry antibiotic degrading genes and enzymes. They are capable of producing enzymes that can degrade antibiotics by cleaving them.

Therefore, option B. plasmids are double-stranded molecules that confer protection to prokaryotic cells.

You are replicating Gregor Mendel's famous experiment with sweet peas. The genotype for dominant smooth-seeded parent is designated AA, while the genotype for the wrinkled-seeded parent is aa. Using a punnet square predict the first generation for this cross. What are the genotypic and phenotypic ratios? SHOW ALL WORK.

Answers

Answer:

The correct answer is -

A. genotype ration = 1/1 or 100% of Aa.

B. phenotype = all smooth-seeded.

Explanation:

According to the question, in this experiment, the smooth seed is the dominant trait over the wrinkled seed. The wrinkled seed is recessive, therefore, represented by aa and dominant is represented by AA

gametes: A and A from smooth seeded parent and a and a from the wrinkled-seeded parent.

Punnett square:

       A          A

a      Aa       Aa

In this cross of F1 generation, all the offsprings are Aa in genotype 4/4 or 1/1 or 100 percent chances.
