9. Halobacterium has a photosynthetic membrane that is colored purple. Its photosynthetic action spectrum is exactly complementary the action spectrum for green plants. What wavelengths of light do the Halobacterium photosynthetic pigments absorb
Answer:
Yellow-green
Explanation:
Let us remember that the colour that is transmitted is always complementary to the colour that is absorbed.
Hence, if a substance absorbs a particular colour, it will transit the colour complementary to that absorbed colour.
The complementary colour of yellow-green is purple hence yellow green light of wavelength 560 - 580 nm is absorbed.

In addition to oxygen, which gases make up the largest percentage of Earth's atmosphere?
Answer: Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere's mixture of gases.
Explanation:
In addition to oxygen, the gases that make up the largest percentage of Earth's atmosphere may significantly include nitrogen, argon, carbon dioxide, etc.
Why oxygen is essentially required for living organisms?Oxygen is essentially required for living organisms because it helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their noses and mouth into their lungs.
Oxygen gives our cells the capability in order to break down food in order to get the energy they need to survive. Oxygen consists of 21% of the total earth's atmosphere along with 78% of the nitrogen and 1% of all rest of the gases like argon, carbon dioxide, etc.

The energy stored in the bonds of glucose comes from what?
What do animal cells need to make energy?
Answer: Eating.
Explanation:
Animals obtain energy by eating plants or animals. The only form of energy a cell can use is a molecule called adenosine triphosphate (ATP). Chemical energy is stored in the bonds that hold the molecule together. ADP can be recycled into ATP when more energy becomes available.
Answer:
Food
Explanation:
Animals obtain energy when they eat. So do we, because we have animal cells! If you don't eat you will get weak and your body needs the nutrients that it gets from the food that you eat. So to make adenosine triphosphate (ATP), you need energy and some other factors that go into making ATP.. but that is the just of it.
You need food.

do you think aquatic plants undergo photosynthesis? where/how do aquatic plants obtain the CO2 needed to go through the process
Answer:
Yes. Aquatic plants may take in carbon dioxide from the air or water, depending on whether their leaves float or are under water. The leaves of floating plants, such as lotus and water lilies, get direct sunlight. ... They can take in carbon dioxide from the air and release oxygen into the air.
the chart below lists substances involved in the process of photosynthesis
which statement best describes how these substances interact in photosynthesis
Answer:
C and D combine to produce A and B.
Explanation:
The chart you were given is shown in the image I attached below. The options you were given are the following:
A and B combine to produce C and D. C and D combine to produce A and B. B and C combine to produce A and D. A and C combine to produce B and D.Photosynthesis is a process in which organisms that possess the pigment called chlorophyll (most plants and some protists and bacteria) produce the energy necessary for their survival. With the help of sunlight, they convert water (D), carbon dioxide (C), and minerals into oxygen (B) and glucose (A).
This is why the second option is the correct one.

What type of mechanism is blood sugar
Answer:
Blood sugar regulating mechanism is operated through liver and muscle by the influence of the pancreatic hormones- insulin and glucagon.
Explanation:
... hope this answer may help u.... and for more answers follow me.❤️❤️❤️Your question is interpretable but the mechanism for blood sugar regulation is called negative feedback.This means that when the blood sugar levels increase an enzyme called insuline comes into play and decreases the levels of blood sugar by glycogeneis(syntheis of glycogen) and increases the membrane permeability of cells for glucose. When glucose level decreases an enzyme called gucagon functions that has opposite effects.

Zara had a birthday and was able to choose a pet. The pet that she chose was a beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.
Answer:
See the answer below
Explanation:
Zara should keep Bozo in a separate salt water-containing tank away from the goldfish.
Bozo is adapted to living in salt waters. If it is kept in saltless water like the goldfish, its cells would lyse and the fish may die. The saltless water would be hypotonic to the cells of Bozo and water moves osmotically from a region of high water potential to a region of low water potential. Hence, the cells of Bozo would take-in water, become turgid, and may eventually lyse, leading to the death of the fish.
The goldfish cannot survive in salt water with Bozo because the water would be hypertonic to its cells. Hence, it will lose water to the surrounding salt water due to osmosis and may eventually die of dehydration.

prevents blood from flowing into the atria when ventricle pumps
allows blood to flow between the two ventricles
Answer:
allows blood to flow between the two atria
allows blood to flow from the atria to the ventricle
prevents blood from flowing into the atria when ventricle pumps
allows blood to flow between the two ventricles
prevents blood from flowing into the atria when ventricle pumps
The valves allow the blood to flow in only one direction so for example when the left ventricle contracts the mitral valve prevents the blood from going back into the left atrium.

In another population, the white spot allele frequency is 0.55. What percentage of the moth population has white spots?
Answer:
The correct answer is - 30.25%
Explanation:
Allele frequency in a population is the number of a particular allele in the population divided by the total number of all alleles present in the population for the particular gene.
The population has the allele frequency or q = 0 .55
So, the percentage of the white spots moth in this moth population would be -
q^2 = (0.55)^2
q^2 = 0.3025
q^2 = 0.0325 *100
= 30.25 %
