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.
The spherical shape Bacteria is called cocci , the rod shape bacteria is called bacilli and the spiral shape bacteria is called spirilla
The body will stop making proteins that need it
Answer:
<em>B: The drug is a small charged molecule</em>
Explanation:
Substances can passively diffuse in and out of the cell via the cell membrane in two ways;
- Simple diffusion
- Facilitated diffusion
The cell membrane allows small molecules or ions to freely diffuse across it in response to concentration difference between the inner and outer parts of the cell membrane. This is known as simple diffusion.
In facilitated diffusion, special proteins in the cell membrane, known as channel/carrier proteins binds with molecules and facilitates their diffusion across the cell membrane by carrying them through special channels in the membrane.
Hence, to support the alternative hypothesis that the new drug will exhibit simple diffusion across the plasma membrane, the drug should be a small charged molecule.
<em>Correct option: B</em>
The answer is SPORES.
Some bacteria, take for example clostridium can be killed with heat but still leave their spores.
They are heat-resistant spores that may survive cooking and later grow and produce large numbers of cells if the storage temperature is appropriate for their growth.
<u>Answer:</u>
<em>Caurepa taxifolia is an invasive species of algae and is listed in the IUCN list of 100 invasive species.
</em>
<u>Explanation:</u>
In is an algae usually found in the pacific ocean. It was earlier used in aquariums as an <em>ornamental species of algae</em>. The dangerously invasive nature overshadows its attractive appearance.
It is inedible and increases in numbers at a surprisingly <em>accelerated rate.</em> The growth of other plants is difficult in areas dominated by the Caurepa taxifolia. The introduction of this <em>algae was in the Meditteranian sea.
