Answer: The true statements about protein digestion and hydrolysis are;

1. Hydrochloric acid in gastric juices cause protein denaturation.

2. In small intestine trypsin attacks peptide bonds.

3.free amino acids are absorbed by the intestinal wall.

Explanation:

Protein digestion occurs in the duodenum and stomach and it is the breakdown of proteins to amino acids by action of Enzymes like trypsin, pepsin.

Protein is digested by the hydrolysis of carbon-nitrogen bond. Mechanical digestion of protein begins in the mouth and it continues in the small intestine and stomach.

Chemical digestion starts in the stomach where by hydrochloric acid in the gastric juice denatures the protein and convert pepsinogen to pepsin enzyme which convert the protein in food to peptides. Trypsin attacks the peptide bond that involves the carboxyl group which breaks it to polypeptide. Exopepdisases and dipeptidases breaks it down to amino acids. The amino acids released by protein digestion is then absorbed by the intestinal wall

Answer:

The most likely pathway is ER - Golgi - vesicles that fuse with plasma membrane.

Explanation:

The endomembrane system is an extensive sets of intracellular membrane. These system was first discovered in the late 1800s when scientist Camillo Golgi noticed that a certain stain selectively marked only some internal cellular membranes. Golgi actually thought that these intracellular membranes were interconnected, but advances in microscopy and biochemical studies of the various membrane-encased organelles later made it clear the organelles in the endomembrane system are separate compartments with specific functions.

How does the concentration of salt in water affect the rate of osmosis?
Nata [24]
The concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences.
Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.

Answer:

(Indian Leaf Butterfly) CAMOUFLAGED

(Monarch Butterfly) CHEMICAL DEFENSE and COLOURFUL WARNING SIGNALS

Explanation:

The Indian leaf butterflies survives by camouflaging to deceive a potential enemy. They could also seek survival by blending to their presents environment such that a supposed enemy finds it hard to identify with their presence.

The monarch Butterfly are very colourful and are super in defending themselves through chemical means.

By chemical defense, they do well to feed on milkweed which is highly poisonous but they have their way of isolating themselves from the consumed poison.

They also send away predators using their colourful warning signals and bright colours. This colours informs predators that they contain poisonous contents.

When a predator bites a monarch Butterfly, it taste the poisons in the wings of the butterfly and let it go. But if peradventure a birds swallows a monarch, the experience of the taste of the poisons teaches the bird never to hunt a monarch Butterfly again

Which number in the diagram represent the mangroves and algae in a mangrove swamp?
disa [49]

Answer: A. 1

Mangrove swamps are wetland ecosystem found in the coastal area. These are found in regions where water body and terrestrial land meets. These ecosystem are dominated by mangrove trees due to their ability to servive in harsh saline water conditions. The roots of mangrove trees exhibit salt filteration system. These trees are habitat of many bird and animal species. The roots of these trees provide shelter, to underwater aquatic plant and animal species such as algea, prawns, sponges and fishes. Mangroves trees and algea are primary producers of the food chain in mangrove ecosytem. Mangrove tree leaves are eaten up by herbivores insects and algal species are consumed by large number of sea animals. Hence, mangrove tree and algea will be on the 1 number of the food chain.
