Too much of Sodium mineral can to the disturbances in the balance of acids and bases.

Metabolic Acidosis:

It is the condition when the pH of the blood deceased less than the normal 7.4. It is caused by excess of Sodium ion.

When Concentration of the Sodium is increased in the extracellular fluid, the sodium exchanged with Hydrogen ions,

This increases in the hydrogen ions cause metabolic acidosis.

The reciprocal cross would be the best type of cross in to determine if a particular trait is a sex linked trait

The correct option is option c.

Reciprocal cross is basically a technique which used in genetics in order to determine whether a trait is sex-linked or it is autosomal. In a reciprocal cross, two different crosses are performed. The first one with the male parent having the trait of interest and the female parent which is not having that trait. The second cross is done with the female parent having the desired trait and the male parent not having the trait.

If the trait is found to be autosomal, the results of the two crosses will be the same but if the desired  trait is sex-linked, the results will differ depending on which sex carries the trait.

Hence, the correct option is option c.

Answer: Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions The major proteins in chromatin are histones. which helps package the DNA in a compact form that fits in the cell nucleus. Chromatin is like manuals in a factory to teach workers how to make the product. A cell membrane is a thin membrane (a double layer of lipids) enclosing the cytoplasm of a cell.

I hope this helps.

Answer:

Chromatin is a complex of DNA and protein found in eukaryotic cells. The primary function is so package long DNA molecules into more compact, denser structures. This prevents the strands from becoming tangled and also plays important roles in reinforcing the DNA during cell division, preventing DNA damage, and regulating gene expression and DNA replication. During mitosis and meiosis, chromatin facilitates proper segregation of the chromosomes in anaphase; the characteristic shapes of chromosomes visible during this stage are the result of DNA being coiled into highly condensed chromatin.

Answer: Fallopian tube

Explanation:

The fallopian tube is where eggs travel from the ovaries to the uterus

Answer:

it can't be used to make a protein in that cell.

Explanation:

If a gene is not transcribed in a cell, it can't be used to make a protein in that cell. If a gene does get transcribed, it is likely going to be used to make a protein (expressed). In general, the more a gene is transcribed, the more protein that will be made.

The transcription is affected as when the gene has not been transcribed the protein will not make. When a gene is transcribed, protein synthesis can happen.

Gene expression begins with transcription. To create an RNA molecule, the DNA sequence of a gene must be copied. RNA polymerases, which join nucleotides to create an RNA strand, carry out transcription (using a DNA strand as a template).

A gene cannot be used to produce a protein in a cell if it is not transcribed there. If a gene gets transcribed, it will probably be used to produce a protein (expressed). In general, more protein will be produced the more a gene is transcribed.

Therefore, the transcription is impacted since the protein cannot be produced if the gene is not transcribed. Protein synthesis can take place when a gene is transcribed.

A microscope is which produces large images of tiny  substance and provide observer a close view of minute structures at a convenient scale for examination and analysis.

Anatomically the microscope consist of  three structural parts, i.e. head, base, and arm, where head is known as the body and it carries the optical parts in the upper part of the microscope.

Base of microscope is used to support  and carries microscopic illuminators and Arms connect the base and the head and the eyepiece tube to the microscope base.

The optical parts are basically applied for the  view, magnify, and production of an image from a specimen placed and the various parts.

To determine if one trait could affect the inheritance of another trait

The parietal lobe, which is located in the middle of the brain, aids with object identification and spatial relationship understanding (the ability to compare one's body to the surroundings).

Detecting touch and pain in the body is another function of the parietal lobe. Numerous cortical areas are implicated in the nuanced perception of pain according to anatomical, physiological, and lesion findings. The primary and secondary somatosensory cortex, anterior cingulate cortex, insular cortex, and areas of frontal cortex are among these areas. The development of chronic pain following peripheral nerve injury is believed to be influenced by the anterior cingulate cortex (ACC), which is also thought to be critical for acute pain perception. In spite of this, it is unclear how ACC neurons respond to sensory stimuli when experiencing chronic pain.

Answer:

Pretty sure its A if not sorry

Explanation:

The frequency of the dominant allele (p) is approximately 0.982 and the frequency of the recessive allele (q) is approximately 0.018.

To determine if the population is in Hardy-Weinberg Equilibrium, we need to compare the observed genotype frequencies to the expected genotype frequencies under the assumptions of the Hardy-Weinberg Equilibrium.

Let's define our variables:

Under the assumptions of Hardy-Weinberg Equilibrium, the expected genotype frequencies are:

We can use the following equation to calculate the expected genotype frequencies:

p^2 + 2pq + q^2 = 1

Now let's plug in the numbers we have:

Total number of individuals (N) = 552

Number of individuals with purple petals (n) = 546

The frequency of the dominant allele (p) can be calculated as the square root of the frequency of individuals with purple petals:

p = √(n/N) = √(546/552) ≈ 0.982

The frequency of the recessive allele (q) can be calculated as 1-p:

q = 1 - p ≈ 0.018

Now let's calculate the expected genotype frequencies:

p^2 = (0.982)^2 ≈ 0.964

2pq = 2 x 0.982 x 0.018 ≈ 0.035

q^2 = (0.018)^2 ≈ 0.0003

The expected genotype frequencies are:

PP: 0.964 x 552 ≈ 531

Pp: 0.035 x 552 ≈ 19

pp: 0.0003 x 552 ≈ 0.2

Now let's compare the observed genotype frequencies to the expected genotype frequencies:

Number of individuals with genotype pp: 552 - 546 = 6

We don't have enough information to calculate the observed genotype frequencies for PP and Pp, so we cannot directly compare the observed and expected genotype frequencies.

However, we can check if the conditions of Hardy-Weinberg Equilibrium are met:

If all these conditions are met, then the population is in Hardy-Weinberg Equilibrium. In this case, we can assume that the population is in Hardy-Weinberg Equilibrium since we don't have any reason to believe that the conditions are not met.

X represents ATP (Adenosine TrisPhosphate) or simply put Energy.

The equations represent two biochemical processes that occur in living organisms, and here the letter X represents a molecule produced from process one, which is the ATP, or the energy.

Glucose oxidation is important in the cell because it provides the majority of the energy, which is ATP, if the glucose is completely oxidized by oxygen, whereas fermentation occurs in the absence of oxygen and produces only 2 ATP. The glucose oxidation is important for the ATP production that is required by the active processes, and along with the energy, water and carbon dioxide are released.

Answer:fter photosynthesis, plants release oxygen into the atmosphere. This is one of the most significant ways that plants contribute to the carbon cycle's oxygen cycling.

In the process of photosynthesis, plants create oxygen and glucose, a form of sugar, from carbon dioxide, water, and sunshine. Animals and other species use the waste product of photosynthesis, oxygen, which is discharged into the atmosphere, for breathing. Overall, photosynthesis and plant respiration are just two examples of the numerous creatures and natural processes that contribute to the intricate process of oxygen cycling in the carbon cycle.

Catalase has no effect on the pH of solutions.

Explanation:

Catalase has no effect on the pH of solutions when added to these solutions because it has a neutral pH of 7. So when Catalase is added to solutions having pH 3, the pH will remain 3, when Catalase is added to solutions having pH 5, the pH will remain 5, when Catalase is added to solutions having pH 7, the pH will remain 7, when Catalase is added to solutions having pH 9, the pH will remain 9 and when Catalase is added to solutions having pH 11, the pH will remain 11.
