Do anaerobic organisms still exist? if no, why not? if yes give two examples.

Brrunno [24]

They do still exist and are mostly microscopic and consist of various types of bacteria. Two examples can be Actinomyces and Bacteroides, both obligate anaerobics, meaning that air actually harms them.

A chemical has an amine group and an organic acid group (carboxyl group). It does not however, have any peptide bonds. It is

777dan777 [17]

Answer:

An amino acid

Explanation:

Amino Acid:

An amino acid, the building block of a protein, is a biomolecule that contains the amino (-NH3+) and carboxylate (-COO−) groups.
Amino acids also contain an organic R- group that defines the properties of the amino acid.
R-groups classify amino acids into different categories such as non-polar, polar, acidic and basic.
The carboxyl group of an amino acid combines with the amino group of another amino acid to form a covalent amide bond or a peptide bond.
Amino acids form polypeptides by the formation of peptide bonds.

Explain how surface water is able to form on permafrosts able to form on permafrost

<h2>explain how surface water is able to form on permafrosts able to form on permafrost</h2>

Just as a puddle of water freezes on a frigid winter night, water that is trapped in sediment, soil, and the cracks, crevices, and pores of rocks turns to ice when ground temperatures drop below 32°F (0°C).

Which of the following statements correctly describes the relationship between biodiversity and sustainability? (1 point)

laila [671]

The statement that correctly describes the relationship between biodiversity and sustainability is, biodiversity increases while sustainability decreases with an increase in the number of species in an ecosystem.

<h3>What do you mean by Biodiversity?</h3>

Biodiversity may be defined as the sum total of all the living organisms living in a particular ecosystem.

As the number of species increases, biodiversity also increases because both are directly proportional to one another.

While the species enhancement negatively impacts the sustainability of the environment.

Therefore, the statement that correctly describes the relationship between biodiversity and sustainability is, biodiversity increases while sustainability decreases with an increase in the number of species in an ecosystem.

What is the driving force for the filtration of blood by the renal corpuscle?

Ipatiy [6.2K]

Answer:

Higher pressure in glomerular capillaries than in the surrounding Bowman's capsule.

Explanation:

The renal corpuscle is composed of the capillary glomerulus and the Bowman's capsule that covers it, there is a space inside the capsule, Bowman's space, where the filtered liquid from the glomerulus passes. The glomerular pressure must be higher than in the surrounding Bowman's capsule, so in that way it forces the filtration and tends to expel fluid from the glomeruli, allowing the passage of water, small molecules of solute and ions.
