1. The exocrine function of the reproductive system in females is stimulated by the hormone produced in the anterior pituitary called follicle-stimulating hormone (FSH), which promotes the production of ovarian follicles. The exocrine product in females refers to the release of eggs or oocytes from the ovaries during ovulation.

2. The endocrine function of the reproductive system in females is stimulated by the hormone luteinizing hormone (LH) produced in the anterior pituitary. LH triggers the release of estrogen and progesterone from the ovaries, which regulate the menstrual cycle, promote the development of the uterine lining, and prepare the body for pregnancy.

3. The exocrine function of the reproductive system in males is stimulated by the hormone produced in the anterior pituitary called luteinizing hormone (LH), which stimulates the production of testosterone in the testes. Testosterone is the primary male sex hormone and is responsible for the development of male reproductive organs and secondary sexual characteristics.

4. The endocrine function of the reproductive system in males is stimulated by the hormone follicle-stimulating hormone (FSH) produced in the anterior pituitary. FSH promotes the production of sperm cells (spermatogenesis) in the testes.

Overall, the reproductive system has both endocrine and exocrine functions, with the anterior pituitary gland playing a crucial role in regulating these functions through the production of specific hormones.

Genetic suppressors are widely used in molecular genetics to study gene function in specific developmental stages and target tissues. Suppressing mutations are second mutations triggered at a different site from the mutation of interest in order to suppress the phenotypic effects caused by the first mutation. Caenorhabditis elegans is a model organism to produce genetic suppressors by taking advantage of its rapid generation time and large populations, which enables the application of rapid and powerful mutation screening procedures in the same experiment. In addition, this species reproduces by self-fertilization, thereby both dominant and recessive suppressors can be easily obtained.

On a carbon-carbon double bond, electrophilic addition results in the intermediate formation of a more stable carbocation.

The SN2 response system includes the nucleophilic replacement response of the leaving bunch (which by and large comprises halide gatherings or other electron-pulling out gatherings) with a nucleophile in a given natural compound.

The electrophilic atom in the vast majority of the nucleophilic substitution reactions covered in this and other textbooks on organic chemistry is a carbon bonded to an electronegative atom, typically oxygen, nitrogen, sulfur, or a halogen.

Electrophiles attack the C8 and C5 carbons of quinoline, which are electron-rich, rather than the C7 position, which is electron-deficient, and produce the following product, as shown in the quinoline reaction. Quinoline's resonance structure demonstrates this.

GGTTAACT is the complement of DNA sequence CCAATTGA.

A sequence of bases in a nucleic acid called a complementary sequence can be used to match base pairs to create a double-stranded structure. For instance, G-T-A-C is the complementary sequence to C-A-T-G, where each letter represents a different DNA nucleotide.

Every DNA sequence has a counterpart sequence running in parallel since DNA has two strands. Adenine (A) is always coupled with Thymine (T) in the complementary sequence, while Cytosine (C) is always paired with Guanine (G).

Natural complementary DNA plays a crucial role in the production of new DNA copies and has emerged as a key experimental tool. The two strands of DNA are unraveled from one another during replication. Each strand is replicated twice, one by a DNA polymerase molecule that runs the length of each strand.

It will affect the plant growth entirely. If it is a plant that needs sunlight to grow it will not grow but if it is a plant that needs shade it will depend on the hade to grow

Explanation:

The most likely explanation for the decrease in the density of gas particles in a section of Earth's atmosphere is that the air pressure in that section of the atmosphere decreased.

Density is defined as mass per unit volume. In the case of a gas, density is directly related to the number of gas particles (molecules or atoms) present in a given volume. When the air pressure decreases, it means that there are fewer gas particles exerting force per unit area. As a result, the density of gas particles in that section of the atmosphere decreases.

Air pressure is the force exerted by the gas particles on the walls of the container or the surroundings. It is influenced by several factors, including temperature, altitude, and the presence of other gases. Changes in these factors can cause fluctuations in air pressure. For example, if there is a decrease in temperature, the gas particles lose kinetic energy, which leads to decreased pressure and density.

It is important to note that the total number of gas particles in Earth's atmosphere does not necessarily change significantly over short periods of time. The atmosphere is composed of a vast number of gas molecules, and while there may be variations due to natural processes, such as volcanic eruptions or biological activities, these changes are relatively small compared to the overall composition of the atmosphere.

Therefore, the most likely explanation for the decrease in density of gas particles in a section of Earth's atmosphere is a decrease in air pressure, which can occur due to various factors such as weather systems, changes in altitude, or movement of air masses.

Answer:

h² = 0.6

Explanation:

Before answering the question, we need to know a few concepts.

Artificial selection is the selecting practice of a specific group of organisms in a population -that carry the traits of interest- to be the parents of the following generations.

Parental individuals carrying phenotypic values of interest are selected from the whole population. These parents interbreed, and a new generation is produced.

The selection differential, SD, is the difference between the mean value of the trait in the population (X₀) and the mean value of the parents, (Xs). So,  

SD = X₀ - Xs

Heritability in the strict sense, h², is the genetic component measure to which additive genetic variance contributes. The heritability might be used to determine how the population will respond to the selection done, R.  

h² = R/SD

The response to selection (R) refers to the metric value gained from the cross between the selected parents. R can be calculated by multiplying the heritability h², with the selection differential, SD.  

R = h²SD  

R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),  

R = X₀ - X₁

-------------------------------------------------------------------------------------------------------------

Now that we know these concepts and how to calculate them, we can solve the proposed problem.

Available data:  

According to what we sow previously, we need to find out the value of h².

We know that h² = R/SD, so we need to get R and SD first.  

R = X₁ - X₀

R = 27 - 30

R = -3

SD = Xs -  X₀  

SD = 25 - 30

SD = -5

Knowing this, we can calculate h²

h² = R/SD

h² = -3/-5  

h² = 0.6
