Answer:We need to break apart the food we eat so that our bodies can . . . ... Would make it more difficult for your intestines to break down food. Villi. Their main function is to absorb nutrients into the bloodstream
Explanation:
They all contain carbonyl groups. DNA has carbonyl groups in it's nucleotide ring structures. Every amino acid in a protein has a carbonyl group in its backbone structure. Fats too have carbonyl groups in their structures attached to hydrocarbon chains
Answers:
A) The membranes of the Chloroplast are the
1) Thylakoid membrane 2) Envelope membrane
B) Calvin cycle occurs within the stroma, while light reactions occur within the thylakoid membrane.
Explanation:
Generally, the chloroplast is made up of the; <u>Thylakoid membrane and Envelop membrane</u>. The thylakoid membrane is basically the region for light absorption, thus making it the site for light reactions within the chloroplast.
Calvin cycle, which occurs in the stroma, involves light independent reactions. It occurs shortly after the light-dependent reactions, and further breaks down ATP and NADPH, products of the light reactions.
The stroma is located outside the thylakoid membrane.
For the remaining listed organelles:
1) The Cytosol- It’s the liquid space within the cell. The chloroplast can be found floating within the cytosol of any involved plant cell.
2) Thylakoid space- The space within the thylakoid.
Answer:
oxygen
Explanation:
The answer is tiny organisms known as cyanobacteria, or blue-green algae. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen
During sperm penetration, human eggs are still surrounded by follicular cells.
Therefore, the correct answer is Option D.
<h3>What changes does egg undergo for fertilization?</h3>
- An egg goes through a few changes at the hour of sperm penetration during fertilization.
- These progressions happen at the cell surface, in development, physiology and gene expression.
- For fertilization, a sperm should combine with the cell membrane and afterward infiltrate the egg cells.
- Infiltration through the egg cell or extracellular matrix (ECM) is a troublesome task.
- The acrosome of the egg goes through acrosomal reaction to get through the hard shell of cell.
- To go through the follicle cells encompassing the egg or oocyte, the sperm discharges hyaluronidase enzyme.
- This chemical isn't delivered until the sperm comes into contact with the egg cell's zona pellucida.
