The main molecule found in nucleus is called DNA(deoxyribonucleic acid). This molecule is made of subunits called nucleotides. A nucleotide is made of a nitrogenous base that can be adenine, thymine, guanine or cytosine; a five carbon sugar called deoxyribose and a phosphate group. This molecule controns protein synthesis. Proteins are crucial to the cell's function.

7. This type of organism consists of a group of cells, but there is no specialized relationship between the cells. (a) unicellular (b) multicellular (c) colonial (d) specialized.
it should be B 100% on that
A type of organism which consist of a group of cells without a specialized relationship between the cells is: (c) colonial.
A cell can be defined as the fundamental functional, structural and smallest unit of life, which is typically found in all living organisms.
Basically, all living organisms are broadly divided into two (2) main categories according to their cell type and these are;
Unicellular organisms: these are living organisms with a single cell.Multicellular organisms: these are living organisms that have multiple cells.On the other hand, a colonial organism refers to an organism that comprises a group of cells that do not have a specialized relationship between them. Thus, colonial organism are made up of connected, interdependent group of cells.

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.
WHICH choice refers to a single population in this image?
A The zebras
B The plants
C The animals
D The water
Answer:
would it be the plants
Explanation:
well all plants are the same and the animals there is more than one
In the given image, the zebras can be considered as the single population.
• A single, living thing, which can be an animal, fungus, or a plant is considered as an organism.
• On the other hand, a population is the term given to illustrate several organisms or individuals of a single species, which thrive in a specific geographical region.
• The single population forms an entire species present in the given geographical location.
• In the given figure, the group of zebras forms a single population, that is, if anything happens to that one population, the entire species will get vanished.
Thus, the correct answer is option A, that is, the zebras.

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 %

What is the function (purpose) of the valves which connect the heart chambers?
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
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.

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.

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.
From the provided choices, which color of light does the pigment chlorophyll absorb the most?
A) green
B) Orange
C) blue
D) yellow
Help!!! plz
Answer:
What color light is best absorbed by chlorophyll?
As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.
Explanation:
therefore it is blue
Answer:
Chlorophyll a: This is the most abundant pigment in plants. Chlorophyll a absorbs light with wavelengths of 430nm(blue) and 662nm(red). It reflects green light strongly so it appears green to us.
Explanation:
So in conclusion the answer will be Blue <3 Hope this helps!

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.

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.

Explanation:
Answer:
1. ATP
2. ADP
Explanation:
Thus, ATP is the higher energy form (the recharged battery) while ADP is the lower energy form (the used battery). When the terminal (third) phosphate is cut loose, ATP becomes ADP (Adenosine diphosphate; di= two), and the stored energy is released for some biological process to utilize.
