process of photosynthesis?

Answers

Answer:

Plants convert energy from sunlight into sugar in a process called photosynthesis each plant contains a branched system of tubes called xylem which is responsible for water transport from the roots (where it is taken up) to the leaves (where it is used in photosynthesis).

Plants convert energy from sunlight into sugar in a process called photosynthesis each plant contains a branched system of tubes called xylem which is responsible for water transport from the roots (where it is taken up) to the leaves (where it is used in photosynthesis).

What is mesophyll?

Mesophyll cells are specialized cells present in the plant leaves and are significant for the process of most of the photosynthesis ( that is formation of food that is carbohydrate using carbon dioxide and water in the presence of sunlight).

These cells have chloroplast ( a green colored, membrane bound specialized organelle) where this mechanism of photosynthesis occurs.Plants convert energy from sunlight into sugar in a process called photosynthesis each plant contains a branched system of tubes called xylem which is responsible for water transport from the roots (where it is taken up) to the leaves (where it is used in photosynthesis).

Compared to worms, insects are highly responsive to environmental stimuli. Identify 2 external nervous system adaptations shown that make this possible in the insect?

Answers

Answer:

Eyes, Antenna and Hairs on their cuticle

Note: There are no diagrams or attachments provided.

Explanation:

Eyes

The eyes of insects serve the function of vision. Insects eyes are of two kinds; simple eyes or ocelli, and compound eyes. The simple eyes or ocelli can sense only light, darkness, and movement. The compound eye which consists of individual light receptive units called ommatidia can distinguish brightness and colour. More ommatidia in an insect's compound eye results in more clarity of vision

Hairs

Tiny hairs known as setae found all over the cuticle of insects are sensitive to vibration touch and sound and therefore serve as sense organs of touch and sound for insects.

Antenna

The antenna in insects serves various sensory functions such as sensing touch, air motion, heat, vibration (sound), and especially smell or taste.

1. The cells in our bodies are surrounded by these types of solutions.

3. When an animal cell is places in this solution, it will burst (get layer)

4. When an animal cell is placed in this solution, it will shrivel or shrink (get smaller).

5. This is a solution with more solute than the cell.

A) isotonic solution
B) hypertonic solution
C) hypotonic solution

Answers

Answer:

1. The cells in our bodies are surrounded by these types of solutions. → Isotonic solution.

3. When an animal cell is places in this solution, it will burst (get layer)  → Hypotonic solution.

4. When an animal cell is placed in this solution, it will shrivel or shrink (get smaller) → Hypertonic solution.

5. This is a solution with more solute than the cell. Hypertonic solution.

Explanation:

The cells in the body are in a balance of substances —concentration of solutes— between their cytoplasm and the extracellular space. This balance is dynamic in living beings, due to the constant exchange of ions and substances between the intracellular and extracellular space.  For this reason, the extracellular medium is isotonic with the cytoplasm.

A cell can lose or gain water depending on the amount of solutes that a medium has in which it is found, with respect to the cytoplasm. This difference in solutes concentrations produces an osmotic gradient that drags water from the least concentrated solution to the most concentrated, through the process of osmosis, which seeks to achieve an equilibrium of concentrations.

When a animal cell is exposed to a hypertonic solution with a higher concentration of solutesit loses water and tends to dehydrate and become smaller.An animal cell in a hypotonic solution receives water, so it can expand and even burst.

In practice, the concentrations of intracellular and extracellular solutes depend not only on the osmotic gradient, but also on the concentration gradient of substances.

What are forces and how do they affect the motion of objects?

Answers

Explanation:

Force is describe as a push or pull on a body. It causes the motion of a body generally.

Newton's law of motion greatly explains the synergy between force and motion. A body will maintain its position at rest or uniform motion unless if it is acted upon by an external force. When force acts on a body, there is a considerable change in the motion of the body.
