What primary method does the cell employ to ensure gene expression only occurs when necessary?

Limited amounts of specific DNA

Phosphorylation cascade with multiple steps

Receptors that only fit specific hormones

Unique transcription factors made of carbohydrates

Answers

Answer:

Unique transcription factors made of carbohydrates

Explanation:

Gene expression refers to the way by which the genes which contain hereditary materials in the cells are converted to certain proteins. Gene expression is regulated to avoid the wastage of useful energy. Transcription allows the copying of genetic information from the DNA to the RNA.

Transcription factors can activate or deactivate a gene thus hindering its expression. Unique transcription factors help to regulate gene expression.

Answer: receptors that only fit specific hormones

Where does the oxygen released during photosynthesis come from​

Answers

Answer:

Oxygen liberated during photosynthesis comes from the splitting or hydrolysis of water in the green plants. Cornelius van Niel experimentally proved for the first time that the oxygen liberated during photosynthesis comes from water and not from carbon dioxide.

Answer:

Oxygen liberated during photosynthesis comes from the splitting or hydrolysis of water in the green plants.

Oxygen is just a by product of this splitting, and will be removed from the plant.

it was proven by Cornelius Van Niel that oxygen liberated during photosynthesis comes from water not carbon dioxide

(a) The oscilation in the pressure inside arteries and arterioles is called by the cardiac rythm. During ventricular systole the pressure rises and during ventricular diastole it decreases

(b)Because when referring to capliaries there is a smaller diameter in the cross section but the surface is bigger. This means that the pressure decreases and the blood has a steady flow instead of periodic bursts.

Read the information below. You just scratched a mineral sample with your fingernail. Your fingernail measures 2.5 on the Mohs scale and fluorite measures 4 on the Mohs scale. Explain why the mineral sample you have cannot be a piece of fluorite
Please help me I need to write a 3 sentence​

Answers

Answer:

It can't be fluorite because your fingernail is less on the Mohs scale than fluorite. When an object is less than another object on the Mohs scale it doesn't leave a scratch on the other object. Therefore if your finger leaves a scratch on the material then it has to be less than 2.5 on the Mohs scale. Fluorrite is not less than 2.5 on the Mohs scale so it is impossible that it is that mineral.

Question 9
How do animals get nitrogen that is stored in the soil?
O A) Animals do not take in the nitrogen stored in the soil.
O B) Bacteria change the nitrogen into a gas that the animals breathe.
OC) Plants ab orb the nitrogen from the soil and animals can eat the plants.
O D) The animals can eat the soil and absorb the nitrogen through their digestive system​

Answers

Answer: C) Plants absorb the nitrogen from the soil and animals can eat the plants.

Heterotrophs, specifically herbivores and omnivores, are animals that eat plants (autotrophs) to get the nutrients they need. Those that eat the plants get the nitrogen from the plant that has absorbed it from the soil. Omnivores and carnivores eat the herbivores to get nitrogen that way. For more more information, take a look at the nitrogen cycle.

How many atoms of carbon, hydrogen, and oxygen are there in the reactants of photosynthesis?

Answers

Answer:

The reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms. IN HYDROGEN ATOMS  It takes six atoms of carbon (C) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6). These atoms come from carbon dioxide (CO2) and water (H2O). IN OXGYEN It takes six atoms of carbon (C), six atoms of oxygen (O) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6).

In photosynthesis, the reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms.

What do you mean by photosynthesis?

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.

Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants. After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

Describe three other features of a bacterial cell.

Answers

Answer:

hope it helped

Explanation:

Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.

The features of a bacterial cell are the following:

Bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.

They are essential in the decomposition processes of organic matter, necessary for the recycling of elements such as carbon or nitrogen.

They reproduce quickly and by asexual procedures, which consist of the replication of the progenitor cell in two exactly equal to it (binary fission).

They are made up of a single cell without a cell nucleus, but with a nucleoid (an irregular region where the circular DNA of prokaryotes is found).

They have a peptidoglycan cell wall that covers the cell outside the plasma membrane.

Scattered throughout the bacterial cytoplasm are ribosomes (in which protein synthesis takes place) and there are also often plasmids (small non-chromosomal DNA molecules).

Some bacterial cell also have capsules, a rigid protective structure that is outside the cell wall and flagella to move (if they are mobile).

Therefore, we can conclude that bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.

Glucose molecules contain stored energy for plants. Glucose is made from carbon dioxide and water molecules during photosynthesis. What kind of energy do plants use to make glucose molecules? A Electrical B Sound C Light D Kinetic

Answers

Answer:

The correct answer is - C. light.

Explanation:

In plants, glucose is formed or produces by the process called photosynthesis, a process that uses light energy to produce glucose with the help of carbon dioxide and water.

In this process, light energy is converted into chemical energy stored in glucose or sugars. The process involves light energy, CO2, and water and produces, glucose, and oxygen as a by-product.
