What is the major cause of changes in gene expression?

Answers

Answer 1

Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of information from DNA to RNA to protein provides the cell with a potential control point for self-regulating its functions by adjusting the amount and type of proteins it manufactures.

In the leaf cells of a plant, enzymes control the rate at which carbon dioxide is converted into glucose. Which environmental factor would MOST affect the action of the enzyme?

Answers

Answer: The environmental factor that would most affect the action of enzymes in the conversion of carbon dioxide into glucose (photosynthesis ) is the light.

PHOTOSYNTHESIS - Photosynthesis is a process by which plants and other organisms convert light energy into chemical energy, which is then released to fuel the organism's metabolic activities through cellular respiration. Carbohydrate molecules, such as sugars, store this chemical energy, which is created from carbon dioxide and water.

The first photosynthetic species most likely arose early in the evolution of life and used reducing agents such as hydrogen or hydrogen sulfide as electron sources rather than water. In the process of carbon fixation, carbon dioxide is transformed into sugars; photosynthesis uses energy from the sun to turn carbon dioxide into carbohydrate. Carbon fixation is a redox reaction that is endothermic. Photosynthesis is the oxidation of carbohydrate or other nutrients to carbon dioxide, while cellular respiration is the reduction of carbon dioxide to carbohydrate. Carbohydrates, amino acids, and fatty acids are nutrients involved in cellular respiration.

Using the diagram below, answer the following questions:

- True or False. The arrow labeled C represents a transfer of chemical energy to mechanical energy. Explain why this is true or false.
- True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false.
- Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?
- Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.
- Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.

Answers

Answer:

FALSE. The factory uses mechanical energy and when carbon is released into the atmosphere it is the process of chemical energy. ... Arrows C + F represent a release of carbon dioxide. Arrow C shows carbon being released into the air from the factory.Its true because the arrow letter A uses the of solar power from the sun then makes a chemical reaction to make food for the plant so basically photosynthesis. 8.arrow E represents cycling of carbon from living organisms to non-living organisms. this is because it is showing conversion of a carbon from the dead tree to fossil fuel.All the arrows in a combined form are used to show the biogeochemical cycle or the carbon cycle. In this cycle, carbon is cycled between the biotic and abiotic component of the biome. In any biogeochemical cycle, mas and energy are always conserved.

What is one significant drawback to transferring electricity produced by solar energy from states where sunshine is abundant to states where it is not? Electricity made from solar energy is different from fossil fuels, so it needs new types of power lines. Electricity made from solar energy is different from fossil fuels, so it needs new types of power lines. The transfer could only occur during the day because solar energy cannot be stored. The transfer could only occur during the day because solar energy cannot be stored. Electricity produced from solar energy farms must be used locally and cannot be transferred at all. Electricity produced from solar energy farms must be used locally and cannot be transferred at all. The cost to transfer electricity produced by solar energy over great distances can be high.

Answers

Answer:

The transfer could only occur during the day because solar energy cannot be stored.

Explanation:

The transfer of electricity produced from solar energy only occur during the day because solar energy cannot be stored at huge level. At homes, we can easily store the electricity made from solar energy with the help of batteries but for providing electricity to a state where thousands of houses are present, very big batteries are needed to store it which can't be made due to very high cost so that's why the solar energy can not be stored.

Answers

Answer:

1. Mitotic cell division

Explanation:

Embryonic development is the formation of organisms that starts from the process of fertilization. The stages of development represent mitosis.

What is mitosis?

Mitosis is a part of the cell cycle, that produces two identical nuclei and daughter cells from the division of the cell and replication of the parent cell.

From the diploid parent cell, two diploid daughter cells are produced in mitosis. This process is the first and the initial stage of embryonic development that initiates the growth and development of the embryo from the parent cell.

Therefore, option 1. mitosis is the process of embryonic development.

Explain what scientists might be able to learn about the seawater that existed millions of years ago by studying rocks that came into contact with seawater at that time in the past . Use evidence from the text to support your inference.

Answers

Answer:

About composition of water and organisms that lives there.

Explanation:

scientists might be able to learn about the composition of seawater that was present millions of years ago if we study those stones that comes in contact to that ancient seawater because the traces of particles still present on it. This study provides valuable information about ancient times of earth and its natural resources. These rocks also provides animals that were present in that sea water at that time.

Geologists using the aspects of geology and paleontology can study and analyze the evolutionary, physiology and ecological relation of plants, animals and other microorganisms with abiotic and other biotic factors.

The scientists will be able to understand the composition of the organism and the water that resided in the region.

This inference can be supported by:

The stones and rocks present in the seawater will depict the characteristics as they will have traces of particles present on them from the past years.

This evaluation will provide insights into the natural resources and organisms present during the ancient times on the planet.

This will also give data about the organism living in aquatic or terrestrial areas.

Therefore, it will give the composition of water and organisms.
