What is the difference between a guard cell and a white blood cell?
Guard cells are found in plants and white blood cells are found in animals.
What are guard cells?Guard cells are specialised plant cells that regulate gas exchange in the epidermis of leaves, stems, and other organs. They are created in pairs, with a stomatal orifice separating them. What are white blood cells?The immune system's white blood cells, also known as leukocytes or leucocytes, are responsible for defending the body against both infectious diseases and foreign invaders. All white blood cells are created and developed from hematopoietic stem cells, which are multipotent cells found in the bone marrow. All parts of the body, including the blood and lymphatic system, include leukocytes.Guard cells function to allow gaseous exchange and white blood cells are responsible for the functioning of the immune system.

Which of the following statements correctly summarizes the process of photosynthesis?
A. Reactions and the Calvin Benson cycle of the grana release oxygen into the atmosphere.
B. Light dependent reactions convert CO2 to carbohydrates, which light independent reactions use to produce NADPH2 and ATP.
C. CO2 is converted to carbohydrates through reactions fueled by products from the light independent reactions.
D. Reactions in the thylakoids capture free energy from sunlight and use it to convert glucose and oxygen to water and carbon dioxide.
The correct statement would be 'CO2 is converted to carbohydrates through reactions fueled by-products from the light DEPENDENT reactions'. Photosynthesis produces simple carbohydrates.
What is photosynthesis?Photosynthesis is a series of chemical reactions by which plants can produce simple carbohydrates by using the energy from the sun and carbon dioxide.
Photosynthesis has two types of reactions: light-dependent reactions and light-independent reactions.
Light-dependent reactions produce energy (mainly in the form of ATP), whereas light-independent reactions produce carbohydrates (i.e., glucose).

Using an example for each, explain the following ecological concepts.
a) Succession
b) Energy flow between trophic levels
c) Limiting factors
Answer:
1-Ecological succession is the process of change in the species structure of an ecological community over time.
2-Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
3-A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system.

In the graph, “ppm” stands for parts per million. A concentration of one ppm is a ratio of one part to one million parts. Concentrations can also be expressed as a percentage. Why do you believe scientists choose ppm over percentage in some cases?
Answer: very small amounts are easier to express as ppm.
Explanation: 1 ppm = 0.0001 %
Answer:
Concentrations like the ones shown in the graph are relatively small. Writing them as percentages would require decimal points and many leading zeros. Therefore, scientists choose ppm over percentages to show CO2 concentrations.

The heart doesn't have to do as much work to pump blood when in orbit. After only one day beyond Earth's gravity, astronauts have a lower blood volume. They can lose as much as 20 percent of their blood volume while on a space mission. Since the body has less blood to push around and the heart is pushing more blood with each beat, an astronaut's heart rate also slows down to compensate.
