A fly has two alleles for the color of its eyes. the green allele is recessive and is represented by q. the blue allele is dominant and is represented by p. if 44 of 100 organisms are green, what is p?​

Answer:

The statement that is true is B. Specialized cells allow for different organs to work together to perform a function.

Explanation:

The phenomenon of cell differentiation allows different cells to have contrasting structures and functions. Each cell can be shaped according to its function based on this phenomenon.  For example the erythrocytes have a hollow structure which allows it to carry oxygen from the lungs to other parts of the body.

Specialized cells that work together form tissues. For eg, the epithelial cells from the skin and small intestine form the epithelial tissue which functions to protect the body surfaces. And tissues work together to form organs, and different organs work together due to the functioning of specialized cells.  

Answer:

B

Explanation:

Answer:c

Explanation:

the question is asking for another name for red blood cells since they bind with oxygen and hemoglobin in our body.

The component of blood with the greatest affinity for oxygen is the erythrocyte, or red blood cell. This is because erythrocytes contain a protein called hemoglobin that binds to oxygen, enabling it to be transported from the lungs to the body's tissues.

The blood component that has the greatest affinity for oxygen is the Erythrocyte (c). Erythrocytes, also known as red blood cells, are the primary transporters of oxygen in the blood. They contain a protein called hemoglobin that has a high affinity for binding to oxygen, making it essential for carrying oxygen from the lungs to tissues throughout the body.

Lymphocytes (option a) are a type of white blood cell involved in the immune response, Leucocytes (option b) is a general term for all types of white blood cells, and Thrombocytes (option d), also known as platelets, are involved in blood clotting. However, none of these other components bind oxygen like erythrocytes do.

copies of DNA.

Explanation:

edge

During the final stage of the cell cycle, cytokinesis will allow the cell to finish dividing, creating two cells with identical copies of DNA.

Cytokinesis is a crucial process that follows cell division by ensuring that the newly formed daughter cells receive their fair share of organelles, cytoplasm and genetic material.

This event marks the culmination of the cell cycle specifically the M phase and is essential for the continuity of life. As the cell undergoes mitosis or meiosis, its genetic material which are organized in chromosomes is equally divided into two daughter nuclei.

Answer:

The correct answer is C) Passive transport

Explanation:

During the respiration process exchange of gases takes place between lungs and blood. This gas exchange is carried by simple diffusion which is a passive transport. Here gas molecule moves from area of higher concentration to the lower concentration area.

The lung's alveoli are surrounded by blood capillaries in which the concentration of CO2 is high while in alveoli concentration or partial pressure of CO2 is low so CO2 moves from blood to alveoli through diffusion.

In the case of oxygen, the concentration of oxygen is high in alveoli and less in blood inside blood capillaries so oxygen moves from alveoli to blood by diffusion. So the right answer is C.

Answer:

Conduction

Explanation:

Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are closer to together, than in gases, where particles are further apart.

Secondary pollutants are more harmful than primary pollutants. the given statement is true.

Pollutants that originate in the atmosphere are known as secondary pollutants. These contaminants aren't directly emitted by a source (like vehicles or power plants). Rather, they emerge when pollutants produced from these sources combine with molecules in the atmosphere to create a new pollutant.

Secondary pollutants are created by the reaction of primary pollutants with atmospheric chemicals. Ozone, smog, sulfur trioxide, acid rain, hydrogen peroxide, and acetylnitrites are all examples of this. These substances have been changed and are more harmful.

Switching all cars to fuel cells would lead to a significant reduction in harmful emissions, decrease global dependence on fossil fuels, and necessitate a shift towards renewable energy to produce hydrogen. It would also involve challenges like developing a comprehensive hydrogen fuel infrastructure.

If all cars switched from burning fossil fuels to using fuel cells, we would expect several significant changes. First and foremost, there would be a notable reduction in the emission of harmful pollutants, as fuel cells produce water as their only byproduct. Unlike the combustion of gasoline, which releases carbon dioxide, nitrogen oxides, and particulates into the atmosphere, the synthesis of gaseous water from hydrogen and oxygen in fuel cells results in a cleaner environment. Additionally, the global demand for fossil fuels would decrease, potentially reducing the geopolitical tensions associated with oil production and distribution.

Another consequence could be the transformation of the global energy infrastructure. Energy sources would need to shift towards those that can produce hydrogen efficiently, such as solar and wind power, to supply the hydrogen required by fuel cells. This would accelerate the transition to renewable energy resources, further diminishing the carbon footprint of human activity.

However, the shift to fuel cell technology would also present challenges, such as the development of a comprehensive hydrogen distribution network to refuel vehicles efficiently. This would require significant investment and innovation in storage and transportation technologies for hydrogen, which is highly flammable and requires careful handling.

The comparison of the role of ATP in cells with the roles of RNA is that the structure of ATP s made up of ribose sugar, adenine nitrogenous base, and three phosphate groups while RNA is made up of ribose sugar, four nitrogenous bases (adenine, guanine, cytosine, uracil), and one phosphate group.

ATP stands for Adenosine triphosphate. It may be defined as a high-energy compound that provides energy to drive many processes in living cells, such as muscle contraction. It is the major source of energy for use and storage at the cellular level.

Both ATP and RNA possess ribose in their structure. RNA directly involves in the synthesis of protein which plays an essential function in the metabolic processes. While ATP provides direct energy to the cells for their effective functions.

Therefore, the comparison of the role of ATP in cells with the roles of RNA is well described above.
