Explanation:
in q 1, part a, we need to tell what we observed in the growth of plants. we observed that the plant h was groing faster and healthier that plant g due to the fact that it was provided with a nutritive solution.
in its part b, we write the conclusion, i.e the plant which was provided with a nutritive solution grew more as all minerals required by the plants were replenished properly.
In q2, part a, we just compare their physical properties such as the plant g was not as healthy as plant h and plant h grew faster and taller than plant g.
in q2, part b, we just write what the solution is supplying the plant with, you can also check each one of their speciality on the web and write it also.
hope it helps

В
The electron transport chain in cellular respiration releases ATP, and the one in photosynthesis does not.
C
The electron transport chain in cellular respiration uses oxygen, and the one in photosynthesis does not.
D
The electron transport chain in cellular respiration uses NADH, and the one in photosynthesis does not.
Answers
Answer:
c
Explanation:
etc uses oxygen
photosynthesis uses carbon dioxide
The best statements could describe the differences between the electron transport chain in cellular respiration and photosynthesis is the electron transport chain in cellular respiration uses oxygen, and the one in photosynthesis does not. Thus, option C is correct.
What is Photosynthesis?Photosynthesis is a biochemical reaction that combines chemicals with biological species to produce energy. Atoms of hydrogen bond with carbon to form glucose.
Carbon dioxide and hydrogen are the reactants that are used from the environment by the plants to make energy. Glucose and oxygen are the products. Splitting water into oxygen gas, hydrogen ions and electrons produces the energy for subsequent electron and proton transport and provides the energy to produce the sugars the plant needs.
The hydrogen atoms from the environment are absorbed by the plants and are combined with the carbon dioxide to yield glucose or sugar molecules for energy.
Therefore, The best statements could describe the differences between the electron transport chain in cellular respiration and photosynthesis is the electron transport chain in cellular respiration uses oxygen, and the one in photosynthesis does not. Thus, option C is correct.

visceral reflex arcs differ from somatic in that ________.
Answers
Explanation:
somatic reflex occurs in skeletal muscles whereas, the visceral reflex occurs in soft tissue organs.
The difference between visceral reflex arcs and somatic reflex arcs is that visceral turns require two motor neurons.
What are visceral reflex arcs?For instance, somatic reflexes require a direct link between the skeletal muscle and the ventral horn of the spinal cord. The central neuron of a visceral reflex sends a signal to a ganglion, which then sends another signal to the target effector.
While somatic reflexes are aware, visceral reflexes are unconscious. Compared to somatic reflexes, visceral reflexes entail a somewhat slower reaction time.
Visceral reflex arcs use two motor neurons along with glandular tissue and non-skeletal muscle to carry out a reflexive reaction. Skeletal muscles only have one motor neuron, therefore somatic reflex arcs include them.
Therefore, two motor neurons are involved in visceral arcs, which differ from somatic.

how does the flow rate through capillaries affect the gas exchange rate between the blood in capillaries and interstitial fluid?
Answers
Answer:
the gas starts to bow
Explanation:
The flow rate through capillaries affect the gas exchange rate between the blood in capillaries and interstitial fluid by gas starts to blow.
What is interstitial fluid?In terms of nutrition, interstitial fluid serves as a sort of refueling station for our cells. Salt, fatty acids, glucose, and minerals like calcium, magnesium, and potassium are all present in interstitial fluid.
Blood capillaries are where the nutrients in interstitial fluid are obtained. Additionally, metabolic waste products can be stored in interstitial fluid.
A continuous glucose monitor will use a formula to offer a near estimate of what our blood glucose level is likely to be at that particular moment because the glucose level in interstitial fluid is not exactly the same as that in our blood.

Answers
We can see that the cell is shrivelled meaning osmosis has taken place. So it must be salt water
A red onion cell placed in a saline solution will lose water when water moves from the cell to the surrounding hypertonic medium via osmosis, causing the cell to shrivel up.
What is osmosis?The passage of solvent molecules from a lower concentration solution to a higher concentration solution across a semipermeable membrane. It is a passive process that occurs without the use of any energy.
Solvent molecule transfer proceeds from low to high concentration regions until the concentrations on both sides of the membrane are equal.
What are the types of osmosis?An isotonic solution contains the same solute concentration both within and outside the cell.A hypertonic solution has a larger solute concentration outside than inside the cell.A hypotonic solution contains a larger concentration of solutes inside the cell than outside.Thus, we can conclude that when a red onion cell is placed in salt water.
As we can see in the diagram the onion cell shrink which means it is placed in salt water which is a hypertonic solution.
So, option (3) salt water is correct.

During photosynthesis, from where does the energy for converting carbon dioxide into sugar come?
Answers
Answer:
Solar energy is converted to chemical energy in the photosynthesis process, which converts water and carbon dioxide to glucose.
Explanation:
Hope this helps!
During photosynthesis, the energy for converting carbon dioxide into sugar comes from the sun, it is solar energy.
What is photosynthesis?Photosynthesis, the method used by plants and other autotrophic organisms to make food, converts carbon dioxide into glucose and oxygen, both of which are vital for life.
Photosynthesis in plants uses the green pigment chlorophyll and produces oxygen as a byproduct. Plants use their leaves to trap light energy during photosynthesis.
Plants use the sun's energy to convert water and carbon dioxide into glucose, a sugar. Plants use glucose for energy and to generate other compounds such as cellulose and starch.
Therefore, the energy used to convert carbon dioxide into sugar comes from the sun during photosynthesis; this is known as solar energy.
