vekshin13 years ago
8 0
<h3><u>Answer;</u></h3>

The above statement is <u>false</u>

<h3><u>Explanation</u>;</h3>
  • Rocks have different porosity and permeability characteristics, which means that water does not move around the same way in all rocks below ground.
  • Permeability greater than 250 mD are considered very good, while permeability less than 1 mD are considered poor.
  • Low porosity normally results in low permeability, but high porosity does not necessarily imply high permeability. It is possible to have a highly porous rock with little or no interconnections between pores.

Large changes in temperature and acidity interfere with enzyme activity by _
ankoles [38]

Answer: Denaturing

Explanation: Enzymes are made of amino acids that are linked by bonds, amongst those bonds are hydrogen bonds that are very weak. High temperatures and low pH(acidity) breaks those bonds changing the molecular conformation of the enzymes. That way they denature and loss the ability to perform their functions. High temperatures and acidity alter the structure of their active site preventing the substrate from binding to them. While high temperatures denatures enzymes, low temperature renders them inactive.

The population density of frogs in a portion of a pond is 12 frogs per square meter. The size of the entire pond is 370 square m
max2010maxim [7]

Given: The population density of frogs in a portion of a pond is 12 frogs per square meter. The size of the entire pond is 370 square meters.

To find: The total population size of the frogs in the pond.

Method: Using unitary method of proportions

Solution:

Let p be the density of the frogs present per square meter.

Let A denote the total area of the pond.

∴ p = 12 frogs/m² and A = 370 m²

The total number of frogs in the pond is given by,

p \times A = 12 \times 370 = 4440

Therefore, there are 4440 frogs in the pond.

Bingel [31]

Answer:a positive feedback

Explanation: positive feedback is a type of feedback mechanism employed by the body,in which an output is enhanced or acclerated.

In contrast to negative feedback where the body regulates it's internal conditions by reducing the effect of a stimuli,In positive feedback ,the body enhances the effect of the stimuli.

It is not common as negative feedback in homeostasis.

An example is the increasing release of oxytocin to promote contractions during childbirth,until the child is born.

Another example is the accumulation of blood platelet , in the site of blood vessels injury to

cause blood clotting.
