The secondary messengers carry out the effects of non-steroid hormones within the cell. Thus the correct answer is option (B).

The Secondary messenger refers to the tiny molecules and ions that transmit signals from cell-surface receptors to effector proteins. Cyclic AMP, cyclic GMP inositol 1,4,5-trisphosphate (), diacylglycerol (DAG), and calcium are examples of secondary messengers. increases intracellular free temporarily, whereas DAG activates protein kinase C directly.

Phosphatidylinositol is used in two different types of signaling pathways. Phospholipase C converts phosphatidylinositol-4,5-bisphosphate into IP3, an essential component of the Ca-signaling pathway that was previously discussed.

Yolk is a nutrient-rich substance that is found in the egg cells of many organisms, including some invertebrates and some fish. The amount of yolk found in an egg can have a large effect on how the organisms develop.

In many organisms, the amount of yolk in the egg affects the development of the embryo. In Xenopus laevis, a species of frog, more yolk in the egg leads to more unequal cleavage and an uneven distribution of cell types during gastrulation.

When the egg contains more yolk, some cells get more yolk than others, and this causes them to divide more slowly than cells that don’t have as much yolk. This leads to an unequal distribution of cells during cleavage, which can result in an uneven distribution of cells during gastrulation. This uneven distribution of cells means that some cells will migrate further than others during gastrulation, leading to an uneven distribution of cell types in the embryo. This can affect the development of the embryo, as the distribution of cells during gastrulation can determine which tissues and organs will form.

In organisms that undergo gastrulation, the amount of yolk in an egg can also affect the way in which the embryo forms. For example, in the frog, those eggs with more yolk tend to form a larger blastopore, which is the opening from which the gastrula forms. This is because the cells in the egg with more yolk will divide faster and spread to a larger area, which allows for a larger blastopore to form.

The following illustration shows the correct flow of molecules during cellular respiration: Acetic acid, pyruvic acid, glucose, and acetyl CoA

A metabolic process called cellular respiration converts glucose to ATP. Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are steps in cellular respiration. Respiration is the process by which complex molecules' C–C bonds are broken by oxidation within cells, resulting in the release of a significant amount of energy. This procedure is known as cellular respiration because it takes place within the cell. It is a multi-step process that begins with the breakdown of glucose to produce a pyruvate molecule with three carbons. The process here is called glycolysis.

An increase in heart rate and blood pressure would be an example of a biological influence into the development of a pathological fear of the sight of blood.

Blood pressure is the force of blood pressing against the artery walls while the heart beats. High blood pressure, often known as hypertension, occurs when that force becomes excessive and begins to injure the body. If left untreated, it will eventually cause heart and blood vessel damage.

When the heart contracts, the highest systolic blood pressure measures the force pressing against the artery walls. Bottom diastolic blood pressure measures the pressure in the arteries between heartbeats.

Normal blood pressure is 120 mmHg/80 mmHg or less. The dangerous readings are 120-139 mmHg/80-89 mmHg. High blood pressure is defined as readings of 140 mmHg/90 mmHg or greater.

As the sample size is increased, the bias will become smaller because it is inversely related to the population variance.

The population variance divided by N, the sample size, yields the variance of the sampling distribution of the mean (the number of scores used to compute a mean). Therefore, the variance of the sampling distribution of the mean is lower the higher the sample size. The sampling distribution tends to become normal as sample size rises. As a result, the sample distribution takes on a leptokurtic appearance. It only occurs because the variability diminishes as sample size increases since the distribution of the samples closely mimics the population. A chi-squared distribution with a degree of freedom equal to n1, where n is the sample size, represents the sampling distribution of the sample variance (given that the random variable of interest is normally distributed).

2. The dependent variable is the rate of photosynthesis

3. The controlled variables are all other variables involved in the experiment

4. Low amount of gas will be produced

5. Light intensity has a direct correlation with the rate of photosynthesis

Photosynthesis is a process whereby green plants use solar radiation and inorganic materials such as carbon dioxide and water to synthesize organic carbohydrates. During this process, oxygen gas is produced as a by-product.

Thus, in the experiment investigating the correlation between light intensity and the rate of photosynthesis, the input variable is the independent variable. Thus, the independent variable would be light intensity.

The variable that shows the effect of the input variable is known as the dependent variable. Thus, the dependent variable would be the rate of photosynthesis.

The remaining variables apart from dependent and independent variables are controlled variables. The higher the amount of gas produced, the higher the rate of photosynthesis. Thus, low gas production will be observed with a low rate of photosynthesis.
