Answer:

It wouldn't be able to survive

Explanation:

If the pH goes up than the coral reefs wouldn't be able to live and if they can't live there then there wouldn't be any life. There wouldn't be shelter for the fish and if there is no fish then the ecosystem would collapse.

Answer:

Extremophiles are a relatively small group of bacteria that thrive in extreme conditions. An example is Picrophilus torridus

Pathogenic bacteria are the bacteria which cause diseases.

Eubacteria are classified into Chlamydias, Cyanobacteria,Gram-positive bacteria, Proteobacteria, and Spirochetes.

Describe three examples of intracellular digestion by lysosomes
Harlamova29_29 [7]

Answer ;

Phagocytosis is when smaller organisms or other food particles are eaten.

Autophagy is when a damaged organelle or small amount of cytosol becomes surrounded by a double membrane and a lysosome fuses with the outer membrane of the vesicle.

Enzymes break down the material. Food vacuoles fuse with a lysosome, whose enzymes digest the food.

Explanation;

-The Lysosomes are organelles that are responsible for intracellular digestion. Lysosomes are vesicles that contain hydrolytic digestive enzymes capable of breaking down large molecules into smaller ones.

-There are several ways in which different varieties of macromolecules may be digested by lysosomes. One mechanism is phagocytosis, the other is autophagy, which entails the removal of membrane-bounded organelles or other cytoplasmic components through the action of lysosomes, and lastly the hydrolytic enzymes may break down or digest the unwanted materials.

Prokaryotic bacteria are surrounded by a ____________ that contains the ____________ to regulate the entry and exit of materials
lukranit [14]

Prokaryotic bacteria are surrounded by a cell membrane that contains the transport proteins to regulate the entry and exit of materials through the cell, the cell wall to help maintain cell shape and structure, and the capsule, which aids against drying out and protects bacteria from a host's immune system.

<h3><u>Explanation:</u></h3>

Bacteria are the prokaryotic organisms that are found in every part of Earth. These organisms do have an interesting ultrastructure. The coverings of the bacteria are three in layer. They are

A. The outer capsule.

B. The middle cell wall.

C. The inner cell membrane.

The capsule is the outermost covering of bacteria that is formed of different slimy materials. These materials contains hygroscopic substances which can absorb water from the surroundings even when the water concentration in outside is very very low. This layer of protection outside bacteria help them to protect themselves against drying out at dry conditions.

The middle cell wall is formed of polymers of N acetyl glucosamine and N acetyl muramic acid. This layer is chitin in nature and is strong enough to maintain the shape and size of bacteria irrespective of outer conditions.

The innermost layer of bacteria is cell membrane which is formed of proteins and lipids bilayer and this cell membrane contains different transport for proteins which help in transport of different substances like water and nutrients inside the cell by means of active transport or passive diffusion.
