Symbiosis is a proximate and often long-term interaction between two or more different biological species.

1. The exocrine function is stimulated by this hormone produced in the anterior pituitary: follicle-stimulating hormone (FSH), and produces ova (eggs) in the female.

2. The endocrine function is stimulated by this hormone in the anterior pituitary: luteinizing hormone (LH), and produces estrogen and progesterone in the female.

3. The exocrine function is stimulated by this hormone produced in the anterior pituitary: luteinizing hormone (LH), and produces sperm in the male.

4. The endocrine function is stimulated by this hormone in the anterior pituitary: follicle-stimulating hormone (FSH), and produces testosterone in the male.

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.

The direction of wind is SW direction. Hence option D is correct.

Wind is defined as the air movement brought on by the Earth's rotation and the sun's uneven heating of the surface. The uneven heating of the Earth by the sun and the rotation of the Earth result in wind, which is the movement of air. Light breezes to natural disasters like hurricanes and tornadoes are all types of winds. In addition to being a plentiful and limitless resource, wind also generates power without consuming any fuel or polluting the environment.

An anemometer can measure wind speed, and a weather vane or wind vane can detect wind direction. When put with anemometers, many wind vanes can be installed in numerous locations to calculate the overall wind profile of a specific area.

Answer:

Water flows through this type of soil.

The correct option is C ; Both type I and type II topoisomerases. A type I topoisomerase only breaks one strand of DNA, but a type II topoisomerase breaks both strands. Because of this mechanistic variation, the linking number of DNA, L, varies by 1 or 2 for type I and type II topoisomerases, respectively.

Type II topoisomerases function by causing a brief double-stranded DNA break, which is followed by a double-stranded DNA passage event As a result, these enzymes may remove superhelical twists from DNA and untangle knotted or tangled duplex molecules.

Negative supercoiling serves an essential biological purpose by promoting local- and global-strand separation of DNA molecules during transcription and replication.

Answer:

The substances which can dissolve in water are termed polar substances, whereas the molecules or substances, which are unable to attract water molecules are known as non-polar molecules. Some of the examples of polar molecules are lactic acid, valine, ethanol, sulfur dioxide, and hydrogen sulfide.

Explanation:

Polar substances also referred to as hydrophilic substances, are dissolved in water through hydrogen bonding. The substances can be acidic, neutral, or basic in nature.

For instance, lactic acid is miscible in water, such that it forms a colorless solution. Glucose, lactose, and valine are neutral are readily soluble in water, and basic substances like adenine are dissolved in hot water.

The non-polar substances are known as hydrophobic substances, such that they do not dissolve in water.

For example, fatty acids cannot dissolve in water, as they are long chains of carbon and have less density than water. Also, neutral substances like vitamins (A, D, E, and K) and cholesterol are unable to dissolve in water.

Polar substances dissolve well in water as compared to non-polar substances.

Polar substances would dissolve well in water because water is also a polar substance which makes bond with the the polar substances. The partial positive atom of water attracts the partial negative atom of other polar substances making hydrogen bonding between them due to their opposite charges.

These charges enables them to dissolve in each other whereas non-polar substances can't dissolve in water due to absence of poles so we can conclude that polar substances dissolve in water.

Cork formation is a type of secondary growth that occurs in the stems and roots of woody plants. Gum formation, on the other hand, is a type of defense mechanism that occurs in response to injury or infection.

Explanation:

Answer:

Explanation:

The scenario is the following.

A population of yellow lizards lives on an island where there is no natural predator. Males of the species use the yellow color to attract females in reproductive seasons. The brighter the males are, the better their genetic quality is. Females are also yellow, but not as bright as males.

A new hawk species was introduced into the island to control some farm pests. But this hawk species prefer to feed on the lizards. The yellow color of these animals contrasts with the dark background and can be easily seen from the air. So the lizard population suffers from significant predation affecting its size sharply.

Some of the lizards then suffer from a mutation and change their color from yellow to greyish brown, which turns to be better to camouflage on the rocks and get to survive. Individuals with greyish brown color get to reproduce at a higher rate than yellow individuals, who keep being hunted by the hawk.

Eventually, after many generations, the yellow individuals decrease to near zero in the population, while greyish brown individuals increase significantly, with males still being brighter than females.

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

Natural selection is an evolutive force that can act favoring an allele or against it, according to how it affects the fitness of individuals. Natural selection selects beneficial alleles and increases their frequency in the population.

When many organisms in a population sharing the same trait die, it is because they did not have good fitness, so they were not adapted to the environment and its pressures. The alleles coding for that trait were not good for the fitness of the animals, so they do not get to survive.

These individuals die before reproducing, so they could not transfer their genetic charge to the following generation. Eventually, the alleles coding for the trait will decrease in the population, probably near zero. Natural selection is acting against this phenotype. Other alleles will be beneficiated, and their frequency in the population will increase.

This change in alleles frequency is what we call adaptation.

Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.

In many cases, adaptations can be correlated to environmental factors or selective pressures applied by other organisms or habitats.

Let us remember that a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.  

So, in the exposed example, we are focussing on the lizards population.    

• The selective pressure or modeling environmental factor is predation by the introduced hawk.  

• The lizards´ response to predation is the survival of only those that carry mutations ⇒ greyish brown color  

• Natural selection benefits these mutations.    

• Greyish brown lizards survive and increase their fitness.
