What are the abiotic factors in salt marshes?

Biology
1 answer:
nadezda [96]3 years ago
3 0

The abiotic factors in salt marshes  include:

1. High, variable  salinity

2. Low oxygen levels

3. Turbidity

4. Varying temperature

5. Sulphide toxicity

Salt marshes occur in zones between low and high tides. Salt marshes are periodically flooded by tides , so the plants living there have had to adapt to being submerged in salt water.

 Only a limited number of plant and animal species can tolerate the harsh conditions of salt marshes  and therefore salt marshes are generally poor in species.

The right atrioventricular valve (tricuspid) regulates the opening between the _________ and the _________.
Ksju [112]

Answer:

The right atrioventricular valve (tricuspid) regulates the opening between the <u>right atrium</u> and the <u>right ventricle</u>.

Explanation:

Valves are gates that allow the connection between atria and ventricles. The two valves located on the right side (tricuspid and pulmonary) direct the incoming blood from the body to the lung, where it is oxygenated; from there it returns to the left atrium, to later pass through the mitral and aortic valves. The left atrium connects to the left ventricle through the mitral valve and the right atrium connects to the right ventricle through the tricuspid valve.

The normal shape of an enzyme is as shown in structure A. If the enzyme's shape changes to that shown in structure B, what are t
Varvara68 [4.7K]

Answer:

There is no image showing the shape of an enzyme, however, the question can still be answered based on basic understanding. The answers are;

- Less binding of substrate

- won't follow the lock-and-key pattern of enzyme binding

Explanation:

An enzyme is a biological catalyst that regulates the rate of chemical reactions in living systems. Enzymes are proteinous in nature and every protein is made up of an amino acid sequence. The amino acid sequence forms a three-dimensional shape that determines the functionality of the enzyme.

Enzymes catalyze reactions by binding to their substrates in a lock and key pattern. This makes enzymes substrate-specific. If the enzyme's normal shape changes, the following will occur:

- Less binding of substrate

- won't follow the lock-and-key pattern of enzyme binding.

Use a protractor to draw a parallelogram that has two side lengths of 5 inches and 2 inches and two adjacent angles that measure
Irina18 [472]

If the adjacent angles of a parallelogram measure 25° and 155°, the other two angles would measure 25° and 155°

<h3>What is a parallelogram?</h3>

A parallelogram is a quadrilateral (has four sides and four angles) in which both sides are equal and parallel to each other. Opposite angles of a parallelogram have the same measure and the diagonals are equal in length.

If the adjacent angles of a parallelogram measure 25° and 155°, the other two angles would measure 25° and 155° because opposite angles are equal.
