Answer:
poliinators and flagellated sperm
Explanation:
Cycads (phylum Cycadophyta) together with Ginkgophyta, Gnetophyta, Pinophyta, Pteridospermales and Cordaitales belong to the gymnosperms (naked seed-producing plants). They are different than angiosperms which produce encased seeds within an ovary.
Cycads (but also Ginkgo) produce swimming sperm that is different than all other groups which produce sperm without swimming flagella.
Also, unlike other groups of gymnosperms, cycads have specialized pollinators, beetls.
Answer:
The correct answer would be - structure of protein and conformation of the R group of the particular amino acid.
Explanation:
The functional properties such as solubility, color, water retention and absorption, texture, foam formation, curdling and other are decided and depends on the structure of the protein and make up of the R-group attached to particular amino acid.
Each amino acid has a single conformation different from other amino acid and which is extremely stable, this unique conformation has its chemical properties that helps in proteins to perform certain and particular catalytic and structural function.
Thus, the correct answer is - structure of protein and conformation of the R group of the particular amino acid.
Answer:B. Primary consumer
Explanation:The reason why Its b because that primary comsumers are mostly herbivores or the primary comsumer is the first consumer to eat the producer.Hope it helps!
Answer:
The correct answer is - b. Responsible for the formation of ATP
Explanation:
The cell membrane is the outer membrane of all types of the cell including eukaryotic, and prokaryotic cell. The cell membrane surrounds the cytoplasm and cell organelles.
The cell membrane is made up of phospholipids that have a hydrophilic and hydrophobic region in the lipid bilayer. The main function of the cell membrane is to protect the cell, provide support, and regulation what enters and leaves the cell. ATP formation is not produced by the cell membrane.
Answer:
B. Proteins
Explanation:
Salivary amylase is an enzyme that starts the breakdown of starch in the mouth. Gastric glands of the stomach secrete gastric juice, which contains HCl to kill bacteria and denatures proteins, intrinsic factors, and the enzyme pepsin. The chief cells of gastric glands secrete pepsinogen (an inactive form of pepsin).
Pepsin begins the digestion of proteins in the stomach. It breaks down certain peptide bonds between amino acids and thereby, breaks down protein chain into smaller peptide fragments. Pepsin requires a very acidic environment of the stomach (pH 2) and becomes inactive at a higher pH.
