It has been demonstrated that environmental uva and uvb levels have resulted in this feature in homo sapiens:

Answers

Answer 1
Answer:

Answer:

variation in skin color.

Explanation:

The human skin color is determined genetically depending on the amount of melanin. However pigmentation can occur as a results of exposure to uv rays that causes induced pigmentation.  

The sun emits two types of ultra violet rays which can reach can reach the skin namely the uva and uvb. Both type of rays can damage the skin if unprotected. Due to this there was evolution against the damaging rays. More melanin that provides a natural sunscreen to the people leaving in the tropic environment.

A certain plant has a color that can range from green to yellow. Some plants are very green, and some are very yellow, but most are in between. What is most likely true about this trait? A. The color is a Mendelian trait. B. There are only two alleles for color. C. Being yellow is a recessive trait. D. There are several genes that control the color.

Answers

Because there are not strictly green and yellow plants, this means that the color can be affected by multiple genes. If it was only affected by one gene then you would see only the two groups for the color, green and yellow. The answer is D.

In the female body, each egg is surrounded by a _____________ which breaks open when the egg is mature.a. ovary
c. placenta
b. follicle
d. uterus

Answers

The correct answer is the ovarian follicle. In the female body, each egg is surrounded by an ovarian follicle which breaks open when the egg is mature. The ovarian follicle is the one responsible in secreting hormone during the menstrual cycle. 

Which biomolecule forms the cytoskeleton in cells? A Lipids
B Carbohydrates
С Proteins
D Nucleic Acids

Answers

The cytoskeleton is the internal structure that maintains the shape of the cell and is made up of proteins that polymerize into filamentous structures.

What are proteins?

They are biomolecules made up of structural units called amino acids.

The cytoskeleton is a protein-based system found in cells that provides internal support and is constructed of three main types of filaments (proteins), theseare microtubules, microfilaments, and intermediate filaments.

Therefore, we can conclude that the cytoskeleton is the internal structure that maintains the shape of the cell and is made up of proteins that polymerize into filamentous structures.

The dominant perspective in the nature-nurture debate today is called _____.

Answers

Answer:

interactionism

Explanation:

Final answer:

The dominant perspective in the nature-nurture debate today is interactionism or the biopsychosocial model. This view emphasizes the complex interaction of genetic traits and environmental factors in shaping human behavior and development. Subfields like neuroconstructivism further highlight this interaction, illustrating how experiences can shape neural pathways.

Explanation:

The dominant perspective in the nature-nurture debate today is often referred to as interactionism or the biopsychosocial model. This perspective holds that our identities are formed through a mix of both genetic traits (nature) and environmental influences (nurture). It emphasizes how our genetic underpinnings interact with our surrounding environment in complex ways to shape who we become. Interactionism acknowledges the role of genetic traits inherited from our parents including eye color, height, and personality traits. At the same time, it also considers how these traits are expressed and how we interact with the environment, influenced by our unique experiences and conditions of our environment. Similarly, the biopsychosocial model looks at the complex interaction of biological, psychological, and social factors in determining behavior and development. This model posits that these factors are all interlinked and work together to give rise to the complexity of human behavior.

How is nitrogen from the atmosphere, the abiotic part of the ecosystem, converted in to the biotic part of the ecosystem of the ecosystem in organisms?

Answers

In theprocess of the nitrogen cycle.               
The nitrogen cycle is abiogeochemical succession process of nitrogen that involves: fixation,ammonification, nitrification, and denitrification. Like any otherbiogeochemical cycles. This process undergoes and affects the biological, geometricaland chemical aspects in the ecosystem and the abiotic and biotic community. Hence,the nitrogen cycle leads the abiotic component –nitrogen- to contribute to thebiotic community, decomposition and primal production. Further, it becomes anessential part of the environment because some life components are contains it,similarly, amino acids, nucleic acids in RNA and DNA.  




Answer:

Nitrogen takes steps through the Nitrogen Cycle, taking an active role in the lives of organisms and changing forms to meet their needs. In fact, nitrogen is a critical part of the development of plants, many farmers even add nitrogen to plants to make the grow bigger and more fruitful. Even the human body needs nitrogen to, which is good because most of the air we breath is nitrogen.
