What happens to a snail/slug if you pour salt on it? why would this happen?
Answer:
When you pour salt on a snail/slug the water is very quickly pulled out of the cells of the snail's body by a process called osmosis. As it dries out, the snail's body produces a slimy substance to protect itself. The bubbling comes from the slime and air being forced out of the snail's body as it shrivels up. If enough salt is poured on the snail it will die of dehydration very quickly.

The Arizona poppy has adapted to living in areas that receive less rain, but there are still periods of time that a drought occurs. What part(s) of photosynthesis would the plant not be able to perform if there is no rain? What would be the long-term effects on the plant if the drought were to continue? Explain your answer.
Answer:
I guess it would not grow??
Explanation:
Answer:
When plants lose more water than they can take up from the soil, they become water stressed. ... Such drought conditions certainly inhibit the growth of plants. If it goes long enough without water it will die because the plant uses water for a lot of different jobs needed to keep the plant alive, so the long-term effect is that the plant will die if the drought continues.
The equation for photosynthesis can be written as 6CO2 + 6H2O --->
C6H1206 +602. How many oxygen atoms are present in the products of
photosynthesis?
Answer:
six
Explanation:
There are 6 oxygen atoms present in the products of photosynthesis.
What is photosynthesis?Photosynthesis is a process by which green plants, algae, and some bacteria convert carbon dioxide and water into glucose (a sugar) and oxygen, using energy from light. This process takes place in chloroplasts within the cells of plants and is essential for life on Earth, as it produces the oxygen that other organisms breathe and the food that supports the food chain.
The glucose produced by photosynthesis is used by the plant as a source of energy or stored for later use. Additionally, the glucose can be converted into other sugars, starches, and cellulose, which are used to build plant tissues.

The diagram above shows the process of meiosis. The segregation that occurs during meiosis results in a -
a. group of genetically identical cells
b. single fertilized egg cell
c. decrease in the number of cells per organism
d. reduction in the number of chromosomes per cell
Answer:
Its D not b reductions in the number of chromosomes per cell
Explanation:
The segregation that occurs during meiosis as illustrated in the diagram above results in a reduction in the number of chromosomes per cell.
What is meiosis?Meiosis is the division process that results in the formation of daughter cells that are genetically different from one another.
According to this question, the meiotic process is depicted in the diagram above. Four daughter cells are produced as a result of the division process.
However, each daughter cell contains half the number of chromosomes as the parent cell, hence, there is a reduction in the number of chromosomes per cell.

What characteristics does a cell membrane have that the plastic bag does not have?
Answer:
The characteristic that differentiates the cell membrane from a plastic bag is that the membrane is permeable to the passage of substances.
Explanation:
Cell membrane covers the cell and is predominantly formed by a double layer of lipids, which gives it the main characteristic of behaving as a semi-permeable membrane. This indicates that the membrane allows the entry of some substances and prevents the entry of others.
Unlike the cell membrane, a plastic bag is impermeable, preventing the passage of water or any other substance.

List some characteristics of each type of seismic wave. Include what type of material (solids, liquids, or both) each can travel through. Primary wave: Secondary wave: Love wave: Rayleigh wave:
Explanation:
Seismic waves can be categorized into two main groups;
Body waves and Surface waves
Body waves are propagated through a material
Surface waves moves through the surface
Primary waves:
They are called P-waves or primary waves These waves have the fastest velocity of all types of seismic waves - 5 to 8km/sThey can pass through any materials because they are longitudinal waves. They are also called compressional wavesSecondary waves:
These are s-waves or shear waves and are body wavesThey have a velocity of about 1-5km/s These waves are transverse wavesThey cannot pass through a region made up of fluidsLove waves
They are transverse wavesThese waves are surface wavesThey move horizontally on the surfaceLove waves cannot pass through liquidsRayleigh waves
They are surface wavesThey have both horizontal and vertical motionThey can pass through both liquids and solids.On what basis are rocks classified into three

Explanation:
In an experiment, a scientist isolates mitochondria from living cells and suspends them in two different buffered solutions. One solution is maintained at pH 4, while the other solution is maintained at pH 9. The
scientist finds that mitochondria in the solution at pH 4 continue to produce ATP but those in the pH 9 solution do not
The results of the experiment can be used as evidence in support of which of the following scientific claims about mitochondrial activity?
Mitochondria in a cell free environment are unable to convert thermal energy into ATP.
The electron transport chain pumps electrons from the cytosol to the mitochondrial matrix,
CATP production in mitochondria requires a hydrogen ſon gradient that favors movement of protons into the mitochondrial matrix.
D
ATP synthase molecules change their orientation in relation to the proton gradient across the mitochondrial membrane.
Answer:C
Explanation:
The scientific claim 'ATP production in mitochondria requires a hydrogen ion gradient that favors the movement of protons into the mitochondrial matrix' SUPPORTS mitochondrial activity (Option C).
Cellular respiration is defined as a group of metabolic reactions by which cells can generate ATP (the energy coin of the cell), by using oxygen and the energy released in the chemical bonds of foods (e.g., glucose).Cellular respiration has three main types of reactions: glycolysis, the acid citric cycle and oxidative phosphorylation.Glycolysis occurs in the cytoplasm, whereas the citric acid cycle and oxidative phosphorylation occur in the mitochondria.During oxidative phosphorylation, the movement of electrons through a series of carriers is coupled to the generation of an electrochemical proton (H+) gradient across the inner mitochondrial membrane.Subsequently, this proton (H+) gradient is then used to generate ATP by using an ATP synthase.In conclusion, the scientific claim 'ATP production in mitochondria requires a hydrogen ion gradient that favors the movement of protons into the mitochondrial matrix' SUPPORTS mitochondrial activity (Option C).
