Plant cell under the microscope

The structure and shape of the cell are more rigid when compared to animal cells as plant cells have a rigid cell wall that provides a more solid structure to the plant cell. The shape of the plant cell is usually rectangular in shape even though some plant cells have a triangular shape.

What would happen to the concentrations of ATP, NADPH and Sugars if PSII stopped working?

dezoksy [38]

Answer:

1. ATP - decrease

2.NADPH - decrease

3. sugars - decrease

And True- Both ATP and NADPH are needed to make sugars.

Explanation:

Photosynthesis is a form of biosynthesis that produces glucose from the reactants; it uses energy from sunlight, along with carbon dioxide and water. It happens in the chloroplast in two phases; the light-dependent and dark reactions. In the light reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.

Chlorophyll forms photosystems of proteins known as complex proteins (PS I & PSII). PS II absorbs and moves the reaction center with light energy.

H+, and oxygen, are formed from a water molecule as it's broken apart.
From photosystem II, electrons are transferred to photosystem I.
ATP is synthesized from ADP along with inorganic phosphate.
To form NADPHH, H+ is added to NADP

If PS II no longer works, there will be less ATP, NADPH, (both used later on) and no sugars produced.

In the dark reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of CO2 with Ribulose 1,5-bisphosphate (RuBP).

Answer

C. Tagging and wildlife tracking

Explanation

Wildlife tracking is a process employed by biologists and scientific researchers including conversational agencies to remotely the movements and migratory patterns of free-ranging wild animals using GPS and other sensors. The tracking and monitoring of these endangered species is vital because it helps in the conservation process. Through the monitoring of wildlife, agencies can keep track of animal potters, population demographics and habitat utilization.

The stronger the wind, the larger the particles it _____________ (deposits/erodes).

Lunna [17]

The stronger the wind, the larger the particles it erodes.

The stronger the wind, the larger the particles that are carried away. Erosion is the action of surface processes like wind flow and water flow that carries rocks, soil and dissolved particles from one point to another.

Which of these best explains why mitochondria are called the "powerhouses" of the cell?

Sindrei [870]

Answer:

They generate chemical energy in the form of ATP.

Explanation:

Mitochondria are the powerhouses of the cell because they "burn" or break the chemical bonds of glucose to release energy to do work in a cell. This releases energy (ATP) for the cell. The more active a cell (such as a muscle cell), the more mitochondria it will have.

Describe three different ways to administer drugs to animals

makkiz [27]

Answer:

Subcutaneous injections (SQ) are given under the skin. Intramuscular injections (IM) are given so that the medication is injected into a muscle. Intravenous (IV) is injecting the substance straight into a vein.
