Answer: Option C. "Plasma cells"

Explanation:

An antibody can be defined as a protein produced by the plasma cells which are utilize by immune system able to bind with specific antigen that protects body from diseases.

Plasma cells are antibody-producing cell that originates from B cell. The antibody produced from plasma cells are released into body and lymph, these antibody molecules bind to the target antigen and allow destruction or neutralization.

Hence, the correct option is C.

In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) an
gregori [183]

The question is incomplete, the complete question is;

In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic cellular respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:

photosynthesis: 6CO2 + 6H2O + light ---> C6H12O6 + 6O2

cellular respiration: C6H12O6 + 6O2 ----> 6CO2 + 6H2O + 36 ATP

How do these equations explain why the total amount of O2 and CO2 remains the same?

Answer:

See explanation

Explanation:

If we look at photosynthesis and cellular respiration, we will realize that the both are complementary processes. The product of one process is the input material for the other process.

Respiration and cellular respiration helps to balance the amount of O2 and CO2 in nature because photosynthesis takes in CO2 and releases oxygen while cellular respiration takes in oxygen and releases CO2. This maintains the delicate balance between the both gases in nature.

The diagram below represents levels of organization in living things. Which term would best represent X?
Nutka1998 [239]

The correct answer is C. Tissue

Explanation:

In the diagram, x is between organ and cell level. This implies this level of organization is smaller than an organ but no as small as one cell. In this context, the most suitable term to add to this level is a tissue because these are structures composed of specialized cells, which shows this level encloses cells. Also, a group of tissues forms an organ; this implies the organ is the level that follows the tissue. Examples of this include muscle tissue composed of muscle cells and that is part of organs including the heart.

When vesicles of the cardiac sarcoplasmic reticulum (CSR) are incubated with ATP Mg^2+ and Ca^2+, they take up Ca^2+ and reach a
abruzzese [7]

Answer

I added 4 and 5 as an attachment due to time constraint.

Explanation:

1. at a steady state ca2+ taken by vesicle = 40n/mol

enclosed volume of CSR = 5μ/mg

concentration of ca2+ in vesicle =

40*10⁻⁶/5x10⁻⁶

= 0.008

= 8x10⁻⁹mol/L

2. radius of circle =75nM

volume = 150nm

volume of vesicle = 4/3 x pi x r³

= 1.33 x 3.14 x (75x10⁻⁹)³

= 1.77 x 10⁻²¹

when we convert this we get

1.77x10⁻¹⁸L since 1m³ is equal to 100oL

surface area =4x3.14x(75x10⁻⁹)²

= 12.56x5.625⁻¹⁵

= 7.065x10⁻¹⁴m²

this is 7.065x10⁻¹⁰cm²

3. number of vesicle/CSR

= 5x10⁻⁶/1.77x10⁻¹⁸

= 2.824x10¹²

surface are = 2.824x10¹² x7.06x10⁻¹⁰

= 19.95x10²
