What the effects of sunlight on the aquatic life inhabiting your body of water on the Indian ocean?
Answer:
Any living creature that lives beneath the Pacific surface will absorb the sunlight for nourishment. If the sun banishes all the living organisms (plants and algae) will suffer due to the lack of photosynthesis. The sun has a massive effect on the aquatic life in the oceans, lakes, or any body of water; including the Pacific Ocean.

A multicellular organism begins life as a single cell-a fertilized egg with a
complete set of chromosomes. The picture in Figure 10-2 above shows how the
cell divides to become two cells, then four cells, eight cells, and so on. Which of
the following statements best describes what happens during this process?
Answer options:
a.) chromosomes are duplicated before cell division so that each new daughter cell has a complete set.
b.) chromosomes are divided evenly during cell division so that each new daughter cell has an equal share of the original set.
c.) chromosomes are stored in the original cell to direct the division of all daughter cells, which do not have their own chromosomes.
d.) chromosomes are randomly distributed during cell division so that some new cells have partial sets while others have complete sets.
Answer:
a.) chromosomes are duplicated before cell division so that each new daughter cell has a complete set.
Explanation:
The cell divisions that allow organisms to grow are called mitosis. Before mitosis, all the DNA is duplicated.
Then, during mitosis, it condenses to form chromosomes. The identical chromosomes align in the centre of the cell. Then, they are equally distributed to among two daughter cells.
These two daughter cells each have a complete set of chromosomes. Each daughter cell identical to the parent cell and to the other daughter cell.

Answer:her arm is puffy, red, and swollen
Explanation:
1)) The average depth of a lake is 10 meters. Do you think sunlight acts a limiting factor the same way it does in the ocean? Why or why not?
2)An area with a high population of crayfish in local lakes and rivers has begun experiencing acid rain, rain that has a pH of 3.0 - 4.0. Predict how this rain will impact the crayfish population.
Answer:
No.
Explanation:
No, the sunlight does not act as a limiting factor the same way it does in the ocean because the lake has lower depth as compared to ocean which is very deep i. e. more than 3000 meters where sunlight does not reach and we know that sunlight is very important for the survival of plants. Sunlight reach in the water about 1000 meters so plants can survive and do photosynthesis due to its low depth.
Acid rain will impact the crayfish population because acid rain decreases the pH of water and this lower pH causes death of the crayfish and also the food of crayfish and thus lower the population of crayfish due to unavailability of food..

Without this process, life would cease to exist because it is the first step in energy transfer from the sun.
Cellular metabolism
Cellular division
Oxidation
Photosynthesis
Answer: Photosynthesis.
Explanation: Photosynthesis is the process by which the producers make food by the help of photosynthesis.
This is the first step of the ecosystem, as there will be no food available to the organism if there will be no photosynthesis.
The producers use the sunlight available for the this vital process. It is the first step of the energy transfer.

The cycle of the moon circling the earth is _________
Answer:
The Moon circles the Earth once every 27.3 days – each sidereal month – but its phases repeat every 29.5 days – each synodic month. The difference arises because the Earth itself moves around the Sun by a distance of around thirty degrees each month.

Which of the following is true about the structure of DNA and RNA?
A. DNA and RNA have the uracil nitrogen base.
O
B. DNA is single stranded and RNA is double stranded.
O
C. DNA and RNA have a deoxyribose sugar.
O
D. DNA has thymine and RNA has uracil.
Answer:
Dna and RNA have a deoxribose sugar
The statement (D) is correct. DNA has thymine and RNA has uracil.
What is DNA and RNA?DNA and RNA are both types of nucleic acids, large molecules that are made up of monomers called nucleotides. Nucleic acids are used to store genetic information, which the cell uses to make proteins.
Moreover, nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.
Hence, DNA is a double-stranded molecule that has a long chain of nucleotides. RNA is a single-stranded molecule which has a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating. RNA does not replicate on its own.

Who was Albert Einstien and what was he known for ?
Here ya go , Fivez and marcus UwU
Answer:
Albert Einstein is a German-born physicist and scientist who has created many ideas and theories relating to the study of relative. He is famously known for creating the famous equation [tex]e = mc^{2}[/tex] (Energy equals mass times the speed of light squared).
He was involved in the help of creating nuclear powered- mechanisms (not for destroying things, but for helpful, everyday things). Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously. Nuclear fission takes place when a heavy atomic nucleus, such as uranium, breaks into two or more smaller pieces with the release of some energy. During this process some of the mass of the original atom is converted into energy in accordance with the equation [tex]e = mc^{2}[/tex].

Does the plant use all wavelengths of light to carry out photosynthesis? Why does this make plants look green?
Answer:
Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects. ... All photosynthetic organisms have chlorophyll a which absorbs violet-blue and reddish orange-red wavelengths. Chlorophyll a reflects green and yellow-green wavelengths. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.
