Which of the following has the highest average salinity?
w. Mediterranean Sea
x. Atlantic Ocean
y. Arctic Ocean
Z. Gulf of Mexico
Salinity is the measure of how much salt has been dissolved in a body of water. It significantly affects conductivity and has an impact on a variety of chemical properties of natural waters, as well as the biological processes that occur there.
Explain about the salinity?Lake describes the Dead Sea. The Salt Sea is another name for it. With a salinity of 33.7%, the Dead Sea is the saltiest body of water on earth.
Either grams of salt per kilogram of water or parts per thousand are used to express salinity. For instance, your salinity is 1g/kg, or 1 ppt (ppt, or ), if you have 1 gram of salt and 1,000 grams of water. Salt content in freshwater is typically less than 0.5 ppt.
The Atlantic Ocean is the saltiest of the five ocean basins. Near the equator and at both poles, salinity generally decreases noticeably, though for various reasons. The tropics, which are close to the equator, consistently get the most rain.
The answer is Atlantic ocean

The 3 Basic Components of the Cell Theory were then complete:
The 3 postulates of the Cell Theory are:
-Every living being is composed of cells, therefore they are the minimal functional unit of life, in their different levels of structural complexity. One single
cell is enough to make up an organism, but also multiple cells can organize in colonies or in a single organism, diversifying their functions and having a margin of independence quite elevated as a whole.
-All of the vital functions of living organisms have a place inside the cell, through biochemical processes and are controlled by substances that the cell secrete. Each cell operates as a unique open system, that exchanges matter, and energy with its environment in a controlled way. Moreover, in each cell of an organism are present the same vital functions that are in the organism itself, that is birth, growth, reproduction, and death.
-Every existing cell comes from a previous cell, by cell division, or by formation from stem cells.

Although animal nervous systems differ in complexity, their nerve cells are still remarkably similar
a. True
b. False
It is true that, Despite the fact that the complexity of animal nervous systems varies, their nerve cells are still remarkably similar.
Nearly all multicellular animals have nerve systems, but their complexity varies greatly. Sponge and the tiny blob-like placozoan and mesozoan organisms are the only multicellular animals without a nervous system. A diffuse nerve net makes up the nervous systems of ctenophores (comb jellies) and cnidarians (such as anemones, hydras, corals, and jellyfish). With the exception of echinoderms and a few worm species, all other animals have a nervous system that includes a brain, a central cord (or two parallel cords), and nerves that radiate from the brain and central cord.
The nervous system's most fundamental roles are to direct an organism's movement and to influence its surroundings (such as through pheromones). Signals are sent from one cell to another or from one part of the body to another to accomplish this. Signals that travel to muscle cells trigger the activation of muscles and signals that travel to endocrine cells triggers the release of hormones into the bloodstream or other internal fluids are the sources of the output that the nervous system produces.

Photosynthesis question: Suppose that a plant had chloroplasts that could carry out the Calvin cycle, but these chloroplasts could not carry out the light-dependent reactions. Explain why these chloroplasts could not carry out photosynthesis to produce sugars.
Light-dependent reactions produce ATP and NADPH that are used during light-independent reactions. Chloroplasts could not carry out photosynthesis to produce sugars because no ATP or NADPH would be available to carry out the Calvin cycle.
What is photosynthesis?Photosynthesis is the process through which plants take solar energy to produce organic compounds. Two alternating and closely related stages are involved in this process.
Light-dependent reactionsDuring this stage, chlorophyll molecules absorb luminous energy from the sun and turn it into chemical energy.
This event takes place in the thylakoidal membrane where the electron transporter chain is located.
The final result is the production of ATP and NADPH and oxygen release from water molecules.
Light-independent reactionsThis stage is known as the Calvin cycle and occurs in the chloroplast stroma.
CO₂ enters the leaves and fixates, producing organic compounds like carbohydrates.
The whole cycle is possible because it uses ATP and NADPH produced during light-dependent reactions.
According to this information, chloroplasts could not carry out photosynthesis to produce sugars because, in the absence of light-dependent reactions, solar energy could not be absorbed, and chemical energy needed for the Calvin cycle would not be produced.

In the figure, Side A is pure water and Side B is a 10% starch solution.
There is a semi-permeable membrane between the sides. Is this osmosis or simple diffusion? Why does the level in side B rise?
Water may pass readily across a semipermeable membrane, but solute cannot. Water travels to the solution side as the membrane divides pure water on the right from solution on the left. Osmosis is the cause of this water flow.
Why did water cross the permeable membrane from one side to the other?Osmosis is the net movement of water across a membrane that is permeable only to certain substances, and it is caused by the concentrations of different solutes on each side of the membrane.
Osmosis is the mechanism through which water diffuses across cell membranes. Osmosis is the process by which water moves from one region of low solute (dissolved material) concentration to another region of high solute concentration through a semipermeable membrane.
Osmosis is the process through which water diffuses across a semipermeable membrane based on the gradient of water concentration across the membrane. Osmosis simply moves water over a membrane, whereas diffusion moves materials both inside cells and across membranes.

What is the meaning of life?
Answer:
The meaning of life is to positively influence as many of the lives around you as possible.
Explanation:
Some people begin to feel a sense of dread when thinking about how little space they take up, and how long they will be alive, because it seems quite small and meaningless in the grand scheme of things.
That, however, is a result of the human brain rationalizing the value and worth of something by how long it exists and how much space it takes up. In reality, something does not need to take up much space, or exist for very long, in order to be worthy and meaningful.
For instance, a hamster is very small and may live only three years before passing of old age. However, if that hamster made a person happy — filled them with joy every day when they arrived home, gave them a reason to get out of bed even when they didn't feel like it, gave them the feeling of love even while being isolated — then it had a very, very meaningful existence.
Humans are very small, and we exist for very short amounts of time, but we have the power to feel and love and change our surroundings, and as long as we leave behind a legacy of even one smile, or even one life saved (no matter how small - a lizard, perhaps), or even one moment of hope, then we will have fulfilled our purpose, and that is all we could ever ask for.
Mr. Cantrell's science class is conducting an investigation to observe the differences between plant and animal cell organelles. The students will observe an onion cell under one microscope, and an animal cell under another microscope. What should students observe as being similar in the onion cell slide and the animal cell slide?
A. Both cell types have a nucleus.
B. Both cell types have a rigid cell wall.
C. Both cell types have large vacuoles.
1. Correct the following paragraph describing pigments, energy and photons.
Photons are the particle that makes up light. Photons with a longer wavelength of light have more energy than photons with a shorter wavelength. Pigments can only absorb photons that have the exact amount of energy required to move
an electron to a higher energy state. If a photon's energy doesn't match exactly, the photon is absorbed. Most plants
have one kind of pigment in their leaves. If a pigment is red, it absorbs only photons with a red wavelength.
2. Correct the following describing the light dependent reactions of photosynthesis.
The first photosystem is photosystem II. In this photosystem, photons are absorbed by pigments in the antenna complex and the energy is used to create an electron at the reaction center. This excited electron is then given to ADP.
The electron carrier is then reduced which provides energy for the electron transport chain to pump H+ ions into the chloroplast stroma. Then, H+ flows through ATP synthase to power the reaction of ATP - ADP + P. The electron that
left the reaction center is replaced through condensation of a water molecule into oxygen and nitrogen. The second photosystem is photosystem I. In this photosystem, photons are absorbed by pigments in the antenna complex and the energy is used to re-excite the low-energy electron from photosystem II at the reaction center. This excited electron is then used to oxidize NADP+ into NADPH.
1. Light has two personalities. Light acts primarily as a wave, but it may also be thought of as a collection of tiny bundles of energy known as photons. If a pigment is red, it absorbs photons of different wavelengths while reflecting photons of the same wavelength.
2. Photosystems, which are huge complexes of proteins and pigments (light-absorbing molecules) that are tuned for light harvesting, play an important part in light reactions. Photosystems are classified into two types: photosystem I (PSI) and photosystem II (PSII).
How to illustrate the information?1 A photon is an electromagnetic energy packet. It is the fundamental unit of all light. The photon is also known as a "quantum" of electromagnetic energy. A photon's energy is proportional to its wavelength: longer wavelength photons have less energy, while shorter wavelength photons have more.
2 Light energy is used in light-dependent reactions to create two molecules required for the next step of photosynthesis: the energy store molecule ATP and the reduced electron transporter NADPH. Light reactions occur in the thylakoid membranes of chloroplast organelles in plants.

Photosynthesis, What goes in, What goes out, and Where within the cell does it occur?
Photosynthesis is the course where plants utilize sunlight, H20, and CO2 to build O2 and energy in the form of sugar.
In the course of photosynthesis, plants take in CO2 and H20 from the air and soil. Inside the plant cell, the H20 is degenerated or give up electrons, at the same time the CO2 is decreased or avails electrons. This converts the H20 into O2 and the C02 into glucose. The plant then discharges the O2 back into the air, and stock energy within the glucose molecules.
Photosynthesis takes place in small organelles called chloroplasts that stock the energy of sunlight. The chloroplasts contain the chlorophyll which is the primary pigment utilized in photosynthesis. The chloroplasts are enclosed by a double membrane and consist of a third inner membrane called thylakoid membrane that builds long folds within the organelle.
Answer - What goes in - CO2 and H20
What goes out - O2 and sugar
Where it occur - sunlight
The light reactions of photosynthesis takes place in the thylakoid membranes of the chloroplast. The light reactions catch energy from the sunlight which they alter to chemical energy and stock in molecules of NADPH and ATP.
Question: Use the image to explain how ATP provides energy to your body
The image shows the process of photosynthesis where conversion of light energy to chemical energy took place by cellular respiration thereby releasing sugar in the form of glucose to provide food to plants and other organisms. ATP is produced by glycolysis and electron transport chain which serves as the energy currency of a cell which are synthesized by the mitochondria.
The image shows a representation of the carbon cycle that could also be related to our human body as well. From the image, it shows that sugar are formed by plants using carbon dioxide and the energy from the sun which can develop for their own nutrients. The process of photosynthesis where conversion of light energy to chemical energy took place by cellular respiration thereby releasing sugar in the form of glucose to provide food to plants and other organisms. When animals, even human beings consumes sugar and they can break them in ATP, which is a molecule that contains energy, can be used in multiple processes.
