When a filament of algae is illuminated with light that is passed through a prism, different segments of algae are exposed to different wavelengths of light. When aerobic bacteria are present, they congregate in highest concentrations in the areas illuminated by the red and blue light. These data suggest a relationship between which of the following variables?
a) Wavelength of light and rate of aerobic respiration
b) Wavelength of light and amt of heat released
c) Wavelength of light and the rate of photosynthesis
d) Carbon dioxide concentration and the rate of photosynthesis
Answer:
The correct answer is C) wavelength of light and rate of photosynthesis.
Explanation:
The given question is a famous experiment conducted by T W Engelmann which is called the action spectrum experiment. In this experiment when light passes through a prism it splits into its constituent colors splits into violet, indigo, blue, green, yellow, orange and red.
Aerobic bacteria require oxygen for their survival. The green algae produce oxygen during photosynthesis. Engelmann released aerobic bacteria to it. it is found that the bacteria accumulated at the blue and red light because photosynthesis and oxygen release were higher there. So, it establishes the relationship between the wavelength of light and photosynthesis.
The energy released by respiration originally came from the sun.

How is relative dating of fossils different from absolute dating?
Answer:
Absolute dating is the actual date of the rock and can also been known as radioactive dating. Relative dating is using the rock layers and fossil records to determine the age of the rock, and it is not the actual age of the rock. :)

All essential amino acids
O must be obtained from the foods we eat.
are found in gelatin.
O come from enzymes.
are made in our body.
Answer:
Essential amino acids must be obtained from the foods we eat.
All essential amino acids must be obtained from the foods we eat. Thus, the correct option is A.
What are essential amino acids?An essential amino acid is also known as indispensable amino acid, these are the amino acids which cannot be synthesized from scratch by the organism fast enough to supply its demand in the body, and it must therefore come from the diet an individual eats. Of the 21 amino acids which are common to all life forms, the nine amino acids that humans cannot synthesize include valine, isoleucine, leucine, methionine, phenylalanine, tryptophan, threonine, histidine, and lysine.
Six other amino acids that are considered as conditionally essential in the human diet, meaning that their synthesis can be limited under special pathophysiological circumstances, such as prematurity in the infant or individuals in the severe catabolic distress. These six amino acids are arginine, cysteine, glycine, glutamine, proline, and tyrosine.
Therefore, the correct option is A.

What is the most important part in the respiratory system?
The lungs.
The lungs are paired, cone-shaped organs which take up most of the space in our chests, along with the heart. Their role is to take oxygen into the body, which we need for our cells to live and function properly, and to help us get rid of carbon dioxide, which is a waste product.
Al the following are parts of the cell theory except-
All cell function in unique ways.
All living things are composed of cells.
Cells are the basic units of structure and function in living things.
All cells are produced from other cells.
Other:
Answer:
All cells are made from the same major classes of organic molecules: nucleic acids, proteins, carbohydrates, and lipids, They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function.

Which of the following is NOT true about Earth’s systems? A.Together, the the geosphere, hydrosphere, atmosphere, and biosphere work to support life on planet Earth. B. Our atmosphere is the place that holds our oxygen. C. There are many systems, or, parts, that work independently. D. There are many , systems, or parts, of the Earth that work together.
Answer:
d
Explanation:
because each part and system as individual tasks or ways to help the earth
The statement that is not true is that there are many systems, or, parts, that work independently. The correct option is C.
What is Earth's system?The application of systems science to the Earth is known as earth system science. It focuses on interactions and 'feedbacks' in particular.
The five Earth systems interact to create the environments we are familiar with.
Everything in the Earth's system can be classified as either land, water, living things, or air. These four components of the system are referred to as "spheres."
They are the "lithosphere" (land), the "hydrosphere" (water), the "biosphere" (living things), and the "atmosphere" (air).
The geosphere is split up into four subsystems: the lithosphere, hydrosphere, cryosphere, and atmosphere.
Because these subsystems interact with one another and with the biosphere, they work together to influence the climate, trigger geological processes, and influence life on Earth.
Thus, the correct option is C.

Typically, acetylation of histone tails leads to ________. Typically, acetylation of histone tails leads to ________. relaxed packaging of the chromatin and increased transcription activation of topoisomerase removal of the protein components of the chromatin from the DNA tighter packaging of the chromatin and reduced transcription increased amounts of euchromatin relative to heterochromatin
Answer:
relaxed packaging of the chromatin and increased transcription.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and are responsible for condensing it to chromatin.
Typically, acetylation of histone tails leads to relaxed packaging of the chromatin and increased transcription.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
