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

Answers

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?

Answers

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.

What do animal cells need to make energy?

Answers

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.

What are polymers? Through which process are they synthesized or made?

Answers

Answer:

Polymers are large molecules with a chain structure that can be linear, branched, and cross-linked. Polymer chains are mainly composed of covalently bonded atoms.

Explanation:

Polymers can be synthesized using  reactants of petrochemical or renewable origin. Polymers can be synthesized in two  methods, by step-growth and chain polymerization. Both ways of polymerization are  random processes during which chains of different lengths are formed.

The basis of step-growth polymerization is the condensation reaction.

how does proteinsynthesis happen in the ribosome​

Answers

First of all, transcription needs to happen inside the nucleus. An enzyme called RNA polymerase uses a strand of DNA as template for mRNA (messenger RNA) synthesis. The mRNA contains the codons. The next step of protein syntheis is called translation and occurs in the ribosome. Codons are groups of three letters that code for an amino acid. When the mRNA comes to the ribosome each codon pairs with an anticodon. Groups of three base pairs that are complementary to codons and are present in the tRNA(transfer RNA).

Each tRNA molecule has an amino acid attached to it and a specific anticodon. Depending on the order of codons proteins are build by binding amino acids.

Explanation:

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.

Answers

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.
