Male pattern baldness may have developed to improve the production of vitamin D because it expands the area of skin that is exposed to sunshine, according to a study. Thus, option A is correct.

Men do receive the major baldness gene from their mothers on the X, or feminine, chromosome.

A 2005 study from the German university of Bonn, which also contributed to the mother myth, backed up this claim. And it is accurate to say that the mother's side has a stronger hereditary influence.

Men don't get fully bald for 15 to 25 years on average. At any age, this process can start. By the age of 60, around two thirds of men are either bald or have a balding pattern. In conclusion, there is no specific age at which you should anticipate experiencing hair loss.

Therefore,  Prostate cancer, which disrupts reproduction and may cause early death, is prevented by this vitamin.

Explanation:

The gradualistic model of speciation is supported by many transitional forms is True .

The gradualistic model, also known as phyletic gradualism, proposes that species evolve slowly and continuously over time through small, incremental changes. This model contrasts with punctuated equilibrium, which suggests that species remain stable for long periods before undergoing rapid bursts of evolutionary change.

Transitional forms, or intermediate species, provide crucial evidence for the gradualistic model. These forms represent species that exhibit a mix of traits from both ancestral and more derived organisms. Fossil records and genetic studies offer numerous examples of transitional forms, demonstrating the slow and continuous evolution of species.

For example, the evolution of land-dwelling tetrapods from fish is supported by the discovery of transitional forms such as Tiktaalik, which shows a mix of aquatic and terrestrial features. Another example is the evolution of birds from theropod dinosaurs, with Archaeopteryx serving as a key transitional form.

Additionally, gradual changes observed in the fossil records of other organisms, such as the evolution of the horse or the development of the mammalian ear, also support the gradualistic model. In these cases, the transitional forms display a clear sequence of small changes that ultimately lead to the emergence of distinct species.

In conclusion, the gradualistic model of speciation is supported by a wealth of transitional forms. These intermediate species demonstrate the slow and continuous nature of evolution, as species accumulate small changes over time that ultimately lead to speciation.

Answer:

b.

Explanation:

The correct answer would be that all the genetic material is duplicated then segregated equally to the daughter cells.

Mitosis has to do with the division of vegetative or non-reproductive cells in the body of organisms. At the interphase stage of each cell cycle prior to mitosis, the genetic materials of the cell are doubled or duplicated.

These genetic materials are then distributed equally to the two daughter cells that are produced at the end of the mitotic process. It thus means that the resulting daughter cells are genetically identical in all ramifications.

The correct option is, therefore b.

Mitosis, followed by cytokinesis, results in the formation of two genetically identical daughter cells because: B. all the genetic material is duplicated then segregated equally to the daughter cells.

Mitosis refers to a type of cell division (duplication) through which a single (1) parent cell produces two (2) genetically identical daughter cells.

In a mitotic division, the two (2) genetically identical daughter cells produced by one (1) parent cell generally have an equal number of chromosomes as their parent cell, this process is referred to as duplication division.

In this context, if a cell divides by mitosis followed by cytokinesis, this would result  in the formation of two genetically identical daughter cells because all the genetic material is duplicated and then segregated equally to the daughter cells.

The growth rate of the shark population when it consists of 30 individuals is 0.9, which is equivalent to 18 individuals per year. Hence, the correct answer is option a) 18.

Logistic growth is a population growth model that takes into account the carrying capacity of the environment, which is the maximum population size that the environment can sustain. In logistic growth, the growth rate of the population decreases as it approaches the carrying capacity.

To calculate the growth rate of the shark population when it is composed of 30 individuals, we need to determine the proportion of the carrying capacity that the population represents. The proportion is calculated by dividing the current population size (30) by the carrying capacity (50), which gives us 0.6.

Next, we multiply the proportion by the maximum per capita growth rate of 1.5 per year. The calculation is as follows: 0.6 * 1.5 = 0.9.

2.do organisms make plants grow faster

3. what type of organism supports the plant the best

Answer:

D- The organisms uses most of the energy it takes in to sustain their own life.

Explanation:

D) Blood pressure does not directly contribute to total peripheral resistance.

Total peripheral resistance refers to the collective resistance of the systemic blood vessels to the flow of blood. It is an important determinant of blood pressure and plays a role in regulating blood flow throughout the body.

Vessel length and diameter (A) contribute to total peripheral resistance. Longer vessels increase resistance, while narrower vessels increase resistance as well.

Blood viscosity (B) also influences total peripheral resistance. Higher viscosity, which can be influenced by factors such as hematocrit and blood composition, leads to increased resistance.

Turbulence (C) can contribute to resistance in certain circumstances, such as when there are abnormalities in blood flow or when there are obstructions in the blood vessels.

However, blood pressure (D) itself is not a direct contributor to total peripheral resistance. Blood pressure represents the force exerted by blood against the walls of blood vessels. While blood pressure can be influenced by changes in resistance, it is not a component of total peripheral resistance itself.

Therefore, option D (blood pressure) is the correct answer as it does not directly contribute to total peripheral resistance.

1. Coriolis effect would deflect the path of the air mass to the west.

2. A horizon would provide the best assessment of the fertility of a soil.

3. Label E is located above Label D.

4. A La Niña can be described as cooler than usual waters in the tropical Pacific

The correct options for 1, 2, 3 and 4  are B, B, D and B respectively.

The Coriolis effect is the deflection of moving air (or an object) due to the Earth's rotation. The air moving in the northern hemisphere is deflected to the right of its intended path due to the Coriolis effect. As a result, in the Northern Hemisphere, air masses traveling from high to low latitudes will be deflected west.

The A horizon, commonly known as the topsoil, contains the most organic matter and nutrients, making it the most fertile layer of soil. This is the layer in which organic components such as degraded plant matter and humus interact with mineral particles to provide an optimal environment for plant growth.

The location at latitude D, which lies above the equator and parallel to the top of the Hadley cell, is where you might expect to find the driest average conditions in the Hadley cell circulation pattern mentioned in the question (north of the equator). Due to the compression, the air in the Hadley cell becomes warm and dry as it descends, resulting in arid or desert-like conditions.

La Niña is a climate phenomenon that causes cooling of sea surface temperatures in the central and eastern tropical Pacific Ocean. It represents the inversion phase of the El Niño–Southern Oscillation (ENSO) cycle.

A standard grasshopper cell has 24 chromosomes.During mitosis, each daughter cell will possess 24 chromosomes.

During mitosis, a type of cell division, the genetic material of a somatic cell is replicated and divided into two daughter cells. In the case of a standard grasshopper cell with 24 chromosomes, each daughter cell will also possess 24 chromosomes.

Mitosis is a highly regulated process that ensures the accurate distribution of chromosomes to the daughter cells. It consists of several distinct stages, including prophase, metaphase, anaphase, and telophase. During prophase, the replicated chromosomes condense and become visible under a microscope. The nuclear envelope breaks down, and the mitotic spindle, composed of microtubules, forms.

In metaphase, the condensed chromosomes align along the equator of the cell. The microtubules from the mitotic spindle attach to the centromere region of each chromosome, forming a complex known as the kinetochore.

During anaphase, the sister chromatids of each chromosome separate and move towards opposite poles of the cell. The microtubules shorten, pulling the chromatids apart.

Finally, in telophase, the chromosomes reach the poles of the cell, and a new nuclear envelope forms around each set of chromosomes. The cytoplasm divides through cytokinesis, resulting in two genetically identical daughter cells.

Therefore, as the grasshopper somatic cell undergoes mitosis, each daughter cell will possess the same number of chromosomes as the parent cell, which is 24 in this case.

The statement that best describes antigenic variation of a parasite is: a) Parasites can change their antigens or create novel antigens.

Antigenic variation refers to the ability of parasites to change their antigens or create new ones. This process is essential for the survival and evasion of the immune system by the parasite. By altering their antigens, parasites can avoid detection and clearance by the host's immune response.

Parasites have evolved sophisticated mechanisms to undergo antigenic variation. They can modify the surface proteins or switch between different antigenic variants. This variation can occur through genetic recombination, gene duplication, or mutation, allowing the parasite to constantly present a different antigenic profile to the immune system.

The ability of parasites to change their antigens or generate novel antigens poses a significant challenge in the development of effective vaccines and treatments. Since the antigens expressed by the parasite can change over time, the immune system may struggle to mount a targeted and long-lasting immune response.

Understanding antigenic variation is crucial in the study of parasitic infections and the development of strategies to control and treat them. By targeting conserved antigens or finding ways to disrupt the antigenic variation mechanisms, researchers aim to develop interventions that can effectively combat parasitic diseases.

Answer:

Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.

Explanation:

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.

Answer:

catabolite activator protein (CAP)

Explanation:

Catabolite activator protein (CAP) is a homodimeric transcriptional activator required for transcription initiation of catabolite-sensitive genes in Escherichia coli. CAP contains a ligand-binding domain at its N-terminus and a DNA-binding domain at its C-terminus. CAP activates transcription by binding at target DNA sites on promoter sequences, thereby enhancing the ability of the RNA polymerase to bind and initiate transcription. CAP binds cyclic AMP (cAMP) to increase CAP’s affinity to DNA and thus activates the transcription of genes for catabolism, such as the lactose (lac) operon genes (the lac operon is a set of genes that encode for enzymes taking part in lactose metabolism).
