Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.

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.

Leona [35]

The Best-Correct Statements as it Pertains to the Control Group and Experimental Group are:

The Control Group Receives No Drug while The Experimental Group Receives No Drug 911-918.

<h3 />

What are the control and experimental group in a study?

The control group in a study is the group in which no changes are applied to the group.

In the control group, the variables are kept constant, hence, the control group is also known as the constant group.

The experimental group in a study is the group to which the treatment being studied is applied. The control group receives the treatment of the variable under study.

Hence, the group that receives the drug 911-918 is the experimental group.

compare the reproductive strategies of a short lived species such as a starfish and a long lived species such as a hippopotamus

AVprozaik [17]

Answer:

Starfish reproduce every winter by ejecting there eggs into the water, since they only live on average 35 years they reproduce about 35 times in their lifetime. Only a couple of the eggs will fertilize and turn into a Starfish.

Hippos are the only mammals in Africa that reproduce in water, Hippos reproduce in May and through June. Hippos usually live to around 40 to 50 years, and most hippos through May and June reproduce more than one time.

Explanation:

Hippos strategies of reproducing are better than Starfish.
