Chlorophyll ‘a’ is serves as the main light-absorbing pigment for photosynthesis.

Further Explanation:

Photosynthesis is a biological process that can be used by plants and other organisms such as blue green algae for the conversion of light energy into chemical energy for the formation of their food. For photosynthesis sunlight, water, and carbon dioxide is required. Chlorophyll ‘a’ is the main light-absorbing pigment for photosynthesis.

Chlorophyll serves as main light absorbing photosynthetic pigment. It plays an essential role in the transformation of light energy into chemical energy. It is found in the thylakoid membrane of the chloroplast of the plant cell. Chlorophyll ‘a’ is serves as the essential and primary pigment for photosynthesis whereas chlorophyll ‘b’ is serves as accessory pigment as it is not essentially required for photosynthesis.

All the photosynthetic organisms have chlorophyll ‘a’ rather than chlorophyll ‘b’. Chlorophyll ‘a’ acts as primary electron acceptor in the electron transport chain. As light is absorbed from the violet-blue as well as orange-red region of electromagnetic spectrum energy is transferred to the reaction center. Chlorophyll ‘a’ also donates two electrons in their excited state to the electron transport chain. In an electron transport chain, it captures solar energy of sun and transforms it into chemical energy that can be used by the photosynthetic organisms for further cellular processes.

The main light-absorbing pigment for photosynthesis is known as chlorophyll. This light absorbing pigment is found in many organisms, primarily in a variety of plant and bacteria species. Chlorophyll is necessary because it allows the light to be absorbed and allow energy to be absorbed by the organism in order to carry out a multitude of metabolic processes.

Ultimately, it is the environment which influences natural selection and thus the evolution of populations

shutvik [7]

Answer:

The given statement is true

Explanation:

Ultimately, it is the environment which influences natural selection and thus the evolution of populations. Is it true or false

Solution

It is true that environment influences the natural selection which is mainly governed by the presence of useful resources that can support an individual. Natural selection leads to emergence of useful trait that can help an individual in adopting traits that can make him/her fit thereby causing evolution of species.

Hence, the given statement is true

What would be the expected result if a competitive, nonhydrolyzable analog of ATP were applied to the cytoplasmic side of a plas

marusya05 [52]

Answer:

The cell interior would experience higher than normal Na+ concentrations and lower than normal K+ concentrations.

Explanation:

Na+/K+ ATPase exists in two forms: Its phosphorylated form has a high affinity for K+ and low affinity for Na+. ATP hydrolysis and phosphorylation of the Na+/K+ pump favor the release of Na+ outside the cell and binding of K+ ions from the outside of the cell. Dephosphorylation of the pump increases its affinity for Na+ and reduces that for K+ ions resulting in the release of K+ ions inside the cells and binding to the Na+ from the cells.

The presence of ATP analog would not allow the pump to obtain its phosphorylated form. Therefore, Na+ ions would not be released outside the cells. This would increase the Na+ concentration inside the cell above the normal. Similarly, the pump would not be able to pick the K+ from the outside of the cell resulting in reduced cellular K+ concentration below the normal range.

Choose one type of water pollution. How did the pollution happen? What negative effects does it have on the environment? What is

vivado [14]

Oil spill or a discharge from pipe from a factory or sewage system. Since this is a single point of origin water pollution, this type of water pollution furnish itself to relatively easy remediation.

What is point source water pollution?

Point-source water pollution is the one type of water pollution which is easy to recognize because it generates from a single source or event and affects a specific area.

The negative effects of single point origin is deteriorating water quality which damage the environment, health conditions.

Destruction of biodiversity is another negative effect of water pollution depletes aquatic ecosystems and prompt unbridled proliferation of phytoplankton in lakes called as eutrophication.

The solution to reduce water pollution is reduce carbon dioxide emissions to prevent global warming and acidification of the oceans. Another is to reduce the use of chemical pesticides and nutrients on crops.
