Answer:
Regulatory genes is involved in controlling the expression of one or more other genes. In prokaryotes regulatory genes often code for repressor proteins.
Explanation:
Why are most genetic diseases caused by recessive alleles?
Answer:
Recessive disease mutations are much more common than those that are harmful even in a single copy, because such "dominant" mutations are more easily eliminated by natural selection.

Phototropism is a phenomenon observed in plants. Phototropism is best described as a plant’s response to light. Auxin is a hormone and signaling molecule found in plants that promotes cell elongation. It is observed that auxin concentrations are lower in the parts of the plant that are closest to light. Auxin concentrations are higher in the parts of a plant that are in the shade.

characteristics of viruses and organisms.
Help me
Answer:
Organisms and viruses both do not contain a DNA enclosing nucleus; however, these organisms differ greatly in the complexity of their structures. Generally an organism is encompassed within a semi-rigid cell wall made of peptidoglycan, which provides structural support. It is classified as gram positive if its cell wall is thick and stains purple when tested for identification. If its cell wall is thin and stains red, it is referred to as gram negative. Under the cell wall, the organisms also has a plasma membrane made up of a phospholipid bilayer with proteins inserted inside. Within its cytoplasm, ribosomes for protein synthesis and a single

PLEASE HELP! WILL GIVE BRAINLIEST. Describe the contribution of photosynthesis and cellular respiration to the exchange of carbon between the atmosphere and the biosphere.
Cellular respiration and photosynthesis are essential to the carbon cycle because cellular respiration involves the intake of oxygen o2 and the exhale of carbon-dioxide co2 into the atmosphere. Where photosynthesis uses the carbon dioxide and water to create oxygen and sugars through energy to repeat the cycle. Respiration in general is a process where carbohydrates are turned into dihydrogen monoxide or water and co2(carbon dioxide). Living organisms together throughout the biosphere and atmosphere work together to continue this because carbon itself is an organic substance.
Answer:
Explanation: Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

Explain this term as related to fossils.
inference
To figure out something based on observation or provided information is termed an inference. Information about the fossils is used by geologists to draw inferences about the organisms that existed long ago.
What are fossils?Fossils are the remains of once-alive organisms that are altered geologically. The dead remains of past lives had been preserved by the earth's crust. They are of interest to geologists and are used to determine the age of rocks
Any living creature – animal, plant, bacteria, and fungus – can be fossilized, but because fossilization is a process of destruction, not all fossilized organisms survive. Most fossilized organisms are consumed, rot or die out in the environment before they can become fossils.
Under normal conditions, only the outermost layers of the most difficult animals and plants fossilize. However, sometimes the conditions are right to fossilize entire soft-bodied organisms.

Hector is demonstrating the properties of light to his class. He tapes two pieces of construction paper—one blue and one red—on the classroom wall. He makes sure all the window blinds are closed to help make the room completely dark. He then instructs another student to turn off all the lights. Hector shines a beam of light from a flashlight onto the blue paper and then onto the red paper. Will the students be able to see the light traveling through the room as it hits the paper? Or will they only see the paper Hector shines the light on? Write down your predictions. Font Sizes
Answer:
Yes because the light from the sun will hit the paper and then when you add the flashlight the beam of light or color will do through
Explanation:
Answer:
I would have to say no. Light travels super fast, and if you did it would be gone in a blink of an eye. Light from a flashlight travels 300,000,000 per second. The only way you can see light traveling from the flashlight is if there is a lot of dust, air, and debris.
