What is mean by photosynthesis?
Answer:
the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water.
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunligh, so we eat the plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the reen pigment found in the chlorookasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Variation in rates of cell division is regulated by a cell-cycle control system—a group of molecules, mostly proteins, within a cell that coordinates the events of the cell cycle. This control system functions through a system of checkpoints. Which assessment occurs at the G2/M checkpoint?
Answer:
See the answer below
Explanation:
At the G2 checkpoint, the accuracy of chromosome replication is assessed along with the cell size and proteins within the cell. The cell division will only proceed if all the listed conditions appear all right.
At the M checkpoint, the correct attachment of spindles to the kinetochores of the sister chromatids of each chromosome is assessed. This is to ensure that chromosomes are correctly separated to the opposite poles of the cell.

Rayleigh wave, surface acoustic waves called Rayleigh waves move along the surface of solids, hence option D is correct.
What is seismic wave?They are commonly employed in non-destructive testing to find flaws and can be created in materials in a variety of methods, as by a localized impact or by piezoelectric transduction.
These include what are known as Rayleigh waves. A Rayleigh wave's amplitude decreases with depth below the surface and becomes noticeably tiny at depths greater than a few wavelengths.
As a result, the disturbance is limited to a solid's surface layers. The motion experienced by the surface layers includes both transverse and longitudinal components.
Therefore, Rayleigh wave type of seismic wave is highlighted in the image.

If the study on the relationship between W. bancrofti and Wolbachia is correct, then combined with the results of the trials, significant numbers of microfilariae do not survive in circulation beyond what time period
Answer:
6 months
Explanation:
First, we must remember that doxycline has an effect only on nematodes, but it cannot effectively prevent microfilariae presented before treatment in the blood of the infected. What we can conclude from this is that it is possible that microfilariae grow and develop, however they will not be able to reproduce, since W. bancrofti is completely dependent on Wolbachia for replication. With that, the microfilariae are running out of time and with about 6 months the patients are free of any trace of microfilariae. So we can conclude that 6 months is the longest time that microfilariae survive in circulation.

Substance A and substance B are mixed together. To separate the mixture, water is added, and substance A is filtered out. Then, the remaining liquid is heated to remove the water, leaving a residue of substance B. Which statement about substance A and substance B could be correct?
Substance A is rice, and substance B is sugar.
Substance A is rice, and substance B is sugar.
Substance A is sugar, and substance B is instant coffee.
Substance A is sugar, and substance B is instant coffee.
Substance A is sand, and substance B is alcohol.
Substance A is sand, and substance B is alcohol.
Substance A is alcohol, and substance B is salt.
The correct answer would be that substance A is rice, and substance B is sugar.
For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.
Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.
Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

6. How are excess salts that accumulate in cells transferred to the blood stream so they can be removed from the body? Explain how this process works in terms of tonicity.
Answer:
Tonicity is the concentration of a solution compared to another, with regards to the number of solutes in these solutions. Too many solutes in a cell may cause them to be hypertonic hence absorb water too much water and lyse. Therefore, these solutes are excreted to the blood-stream through active transport and facilitated diffusion. These solutes are then excreted by the kidneys. If they are not excreted, the osmotic pressure (due to the inflow of water to the bloodstream by osmosis) may cause high blood volumes being pumped by the heart hence high blood pressure
Explanation:
Tonicity is the concentration of a solution compared to another, with regards to the number of solutes in these solutions. Too many solutes in a cell may cause them to be hypertonic hence absorb water too much water and lyse.
What is excreted from the blood stream?The solutes are excreted to the blood-stream through active transport and facilitated diffusion. These solutes are then excreted by the kidneys. If they are not excreted, the osmotic pressure due to the inflow of water to the bloodstream by osmosis may cause high blood volumes being pumped by the heart hence high blood pressure.
Osmosis is the net movement of water across a semi-permeable membrane from an area of lower gradient concentration to an area of higher gradient concentration. On the other hand, tonicity is the ability of an extracellular fluid to make water move into or out of a cell through osmosis. A solution's tonicity is related to its osmolarity or the total concentration of the solutes in a solution.
Therefore, Tonicity is the concentration of a solution compared to another, with regards to the number of solutes in these solutions.

Answer:
Water, high specific heat capacity
Explanation:
The temperature fluctuations are relatively small in Jameson city because takes water longer to heat up and cool down due to its high specific heat capacity because water has high heat capacity that is it absorb alot of heat before it start to get hot. takes more energy to increase the temperature of water compared to other substances which help to regulate extremes in the environment.
Water surrounding cities take longer to heat up and longer to cool down so cities that are near the oceans will tend to have less change and less extreme temperatures compared to inland cities.

When objects of two different temperature are in contact, what happens?
Answer:
The answer is C.
Explanation:
This is because the objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal. We say that heat flows from the hotter to the cooler object.
Energy is transferred from a warmer to a cooler object through the phenomenon of heat. For instance, a large pan of lukewarm water will gain heat from a lit match (a higher temperature object) (lower temperature object). Thus, option C is correct.
What change in temperature when object are in contact?It feels warmer in your hands to hold a hot cup. The heat is moving from one object to another, which is what you are feeling. Your hands receive the hot chocolate's thermal energy.
Heat is exchanged when two objects are at different temperatures. Up until the two items are at the same temperature, the cooler object warms up. Always, heat energy moves from a hot object to a cooler one.
The colder end will get energy from the hot end as it passes through the rod. The temperature will eventually equalize across the entire rod. Wearing gloves is crucial when working with hot metal, for this reason.
Therefore, The warmer object transfer heat energy to the cooler object.
