A. Leaves

Explanation:

The correct answer is (c) muscle fibers are unable to contract. During the recovery period following exercise, oxygen is consumed at above the resting rate, lactic acid is removed from muscle cells, heat is generated, and the muscle actively produces ATP.

Oxygen is consumed at above the resting rate: The body needs oxygen to generate ATP, and during exercise, the body is unable to provide the muscles with the required amount of oxygen. Thus, during the recovery period, the body tries to make up for the lost oxygen by consuming oxygen at a rate that is above the resting rate.

Lactic acid is removed from muscle cells: Lactic acid is produced during exercise, and it contributes to muscle fatigue. During the recovery period, the body removes the lactic acid from the muscle cells to prevent muscle fatigue.

Heat is generated: Exercise produces heat, and the body generates heat during the recovery period to maintain the body's temperature. The body can remove excess heat through sweating. The muscle actively produces ATP: During exercise, the muscles require ATP to contract. However, the body can't provide the muscles with the required amount of ATP during exercise. Therefore, the muscle actively produces ATP during the recovery period to recover the lost ATP.

However, muscle fibers are able to contract during the recovery period. This is because the muscles need to contract to generate ATP. Hence, the correct option is C. During the recovery period following exercise, all of the following are true except muscle fibers are unable to contract. Muscle fibers are not unable to contract; they are just recovering and may have a reduced ability to contract due to fatigue.

The statement "this process is common to all members of eukarya and allows noncoding regions of RNA to be removed so that proteins with the correct amino acid sequence are produced" best predicts the importance of the process being referred to.

This process is called RNA splicing, and it involves the removal of noncoding regions, called introns, from RNA molecules before they can be translated into proteins. This process is essential for the production of functional proteins in eukaryotic organisms, and it is a key step in gene expression. Without RNA splicing, the production of proteins with the correct amino acid sequence would be compromised, which could have severe consequences for cellular function and survival.

A 0.5% saline solution is hypotonic to a cell. It will cause the cell to swell.

The tonicity of a solution refers to its effect on the osmotic pressure and water movement across a cell membrane. In this case, if a 0.9% NaCl (saline) solution is isotonic to a cell, it means that the concentration of solutes inside the cell is balanced with the concentration of solutes in the saline solution.

When a solution is hypotonic to a cell, it means that the concentration of solutes in the solution is lower than the concentration of solutes inside the cell. In the context of the given options, a 0.5% saline solution is hypotonic to the cell.

When a cell is exposed to a hypotonic solution, water moves into the cell in an attempt to balance the concentration of solutes. This influx of water causes the cell to swell or expand.

Therefore, option 3 is correct: 0.5% saline solution is hypotonic to the cell. It will cause the cell to swell.

Answer:

Hemoglobin

Explanation:

Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. With SCD, the hemoglobin forms into stiff rods within the red blood cells. This changes the shape of the red blood cells. The cells are supposed to be disc-shaped, but this changes them into a crescent, or sickle, shape.

The sickle-shaped cells are not flexible and cannot change shape easily. Many of them burst apart as they move through your blood vessels. The sickle cells usually only last 10 to 20 days, instead of the normal 90 to 120 days. Your body may have trouble making enough new cells to replace the ones that you lost. Because of this, you may not have enough red blood cells. This is a condition called anemia, and it can make you feel tired.

The sickle-shaped cells can also stick to vessel walls, causing a blockage that slows or stops the flow of blood. When this happens, oxygen can't reach nearby tissues. The lack of oxygen can cause attacks of sudden, severe pain, called pain crises. These attacks can occur without warning. If you get one, you might need to go to the hospital for treatment.

When a stem cell differentiates and changes in size and shape, specific genes are being EXPRESSED.

Gene expression involves the flow of genetic information from genes (DNA) to RNA and proteins.

Differentiation involves first the transcription of genes to messenger RNAs (mRNAs) and second the translation of these mRNAs to proteins.

During gene transcription, a fragment of DNA called 'gene' is used as a template to create an mRNA in the cell nucleus.

Subsequently, this mRNA travels to the cytoplasm where it is then used as template to create a protein by the process of translation.

In conclusion, when a stem cell differentiates and changes in size and shape, specific genes are being EXPRESSED.

When light reflects off of an object being viewed under the microscope and passes through the lens, it bends towards the eye. This makes the object look bigger than it actually is.

Limitation: Low Resolution. Because optical microscopes use normal white light, the limit of their resolution is 200 nanometres. This means that objects smaller than this cannot be properly viewed by an optical microscope.

Advantages would be of course magnification and higher resolution

as electrons rather than light waves are used, it can be used to analyze structures which cannot otherwise be seen. The resolution of electron microscopy images is in the range of up to 0.2 nm, which is 1000x more detailed than light microscopy.

The main difference between SEM and TEM is that SEM creates an image by detecting reflected or knocked-off electrons, while TEM uses transmitted electrons (electrons that are passing through the sample) to create an image.

All cells share four common components: plasma membrane, cytoplasm, DNA, and ribosomes.

The defining characteristic of prokaryotes is that they lack a membrane-enclosed nucleus.  The single chromosome, usually circular, is tightly wound and compact. The region of the cytoplasm containing the chromosome is called the nucleoid.

Eukaryotic cells are defined by the presence of a nucleus surrounded by a complex nuclear membrane.

The cellular process responsible for the formation of gametes in sexual reproduction is g) meiosis.

Meiosis is a specific kind of cell division that happens in germ cells, which are reproductive cells that create gametes. The number of chromosomes in the daughter cells is halved as a result of two rounds of cell division. Chromosome pairing, crossing over, and recombination occur in the parent cell during meiosis. By moving and trading genetic material between homologous chromosomes, this genetic recombination boosts genetic diversity.

It results in the development of uncommon allele combinations, resulting in genetic variety in the progeny. Homologous chromosomes join up and cross over during the first division of meiosis to exchange genetic material. After that, they split into two haploid daughter cells that have a mixture of DNA from both parents. These daughter cells divide once more during the second division, resulting in a total of four haploid cells with each having half as many chromosomes as the parent cell. The gametes are these haploid cells.

The generation of DNA sequencing technology most appropriate for a 10 Mbp piece of DNA that cannot be fragmented would be the third generation sequencing technology. This technology is based on single-molecule sequencing and does not require the DNA sample to be fragmented into smaller pieces.

DNA sequencing is a process that involves determining the precise order of nucleotides within a DNA molecule. Nucleotides are the building blocks of DNA and include adenine, guanine, cytosine, and thymine. The order of these nucleotides within a DNA molecule determines the genetic code that controls the characteristics of living organisms. DNA sequencing technology has advanced significantly since the discovery of the structure of DNA by Watson and Crick in 1953. Over the past few decades, several generations of DNA sequencing technologies have been developed.

However, the first and second generation sequencing technologies have the limitation of requiring the DNA sample to be fragmented into smaller pieces before sequencing, which can be difficult for larger DNA molecules. On the other hand, third generation sequencing technologies, such as nanopore sequencing, are based on single-molecule sequencing and do not require the DNA sample to be fragmented into smaller pieces.

Therefore, third-generation sequencing technology would be the most appropriate for a 10 Mbp piece of DNA that could not be fragmented into smaller pieces.
