Answer:

(B). an increase in the number of WBCs in the blood

Explanation:

WBCs or white blood  cells are components of immune system that fight against a number of infection-causing agents, such as bacteria, fungi, and viruses. Examples of WBCs include neutrophils, basophils, monocytes, B lymphocytes, T lymphocytes and mast cells.

As these cells help to fight against infection, their number increases at the time of an infection. Hence, an elevated level of white blood cells is used as an indicator of a body infection.

Thus, the correct answer is option (B).

How is loss of biodiversity connected to extinction of organisms?
Mariana [72]

Answer:

In an ecosystem, everything is connected. All ecosystems have some form of food chain and symbiosis. This means that animals rely on each other for life. If one animal were to die then others would be negatively affected. Overall, this means that when biodiversity is lost it becomes harder for organisms to survive. For example, pandas rely on bamboo to survive. So, when it gets cut down and destroyed the pandas also suffer. Additionally, in ecosystems, a wide variety of organisms helps other living creates have more forms of survival. This shows how important biodiversity is.

What is the volume of air that my lungs hold
UkoKoshka [18]

Answer:

Tidal volume

Explanation:

Tidal volume is the amount of air taken into the lungs in a single breath. However, the lungs can hold a total of about 4-6 liters, which is close to ten times the tidal volume. This amount is known as the vital capacity.

On rare occasions, mutations can be beneficial to an organism.<br> a. True<br> b. False
iogann1982 [59]
Yes, this is true, and it is actually one of the organisms driving evolution! Some organisms develop mutations that are actually beneficial (better eye-sight, for example) and they're more likely to pass those to their children that individuals without those mutations!

1. What is the Photosynthesis EQUATION? What is being consumed and what is produced?
Alla [95]
1. 6CO2 + H2O -----> C6H12O6 + 02

2. The idea of photosynthesis or light dependent reactions is to convert solar/light energy into chemical energy by the form of ATP and NADPH. CO2 and Water are consumed and react to release Glucose and 02. Approximately 36-38 ATP produced.

3. Water is the source of hydrogen atoms in the glucose (sugar) created by the photosynthesis reaction.

4 .
Step 1) The light absorbed by chlorophyll causes a transfer of electrons and H+ from H20 molecules already present. This causes the H20 to split into molecular 0xygen (02) and a H+ ion.

Step 2.) The O2 is released (we breathe it) and the H+ bonds to NADP+ creating NADPH

Step 3) ATP is formed through photophosphorylation. (ADP gets a phosphate group added to it creating ATP)

Step 4.) The NADPH and the ATP created here go on to fuel the reactions in the second part of photosynthesis - The Calvin Cycle

5. The Calvin cycle is a metabolic process that uses the carbon from carbon dioxide, along with energy in the form of ATP, to produce sugar.
A G3P molecule contains three fixed carbon atoms, so it takes two G3Ps to build a six-carbon glucose molecule. It would take six turns of the cycle.

6. To help synthesize carbohydrates for energy

7. In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADP +, respectively
