According to the passage all but one is a reason to classify viruses as living which is that they lack mechanisms for metabolic function and is denoted as option D.
<h3>What is a Living organism?</h3>
This is referred to something which exhibits the presence of life and are able to transfer genetic traits from the parent to offspring. Living organisms are also able to perform certain types of activities for it to be referred to as being living.
Example of the activities which are performed by living things include the following below:
Virus is regarded as a living thing because they are capable of protein synthesis and contain a nucleic acid, DNA or RNA. They also have mechanisms for metabolic function which is therefore the reason why option D was chosen as the most appropriate choice.

The options are
A)are capable of protein synthesis.
B)contain a nucleic acid, DNA or RNA.
C)response to changes in the environment.
D)lack mechanisms for metabolic function.
The correct answer is: oxaloacetate
Anaplerotic reactions are chemical reactions that form intermediates that can be used in the further steps of metabolic pathways. These reactions are very important, because it is crucial for the cell to regulate concentrations of TCA cycle metabolites and intermediates.
The reaction in which pyruvate is converted to oxaloacetate is catalyzed by pyruvate carboxylase and it occurs in mitochondria. Also, pyruvate can be converted to L-malate, in a similar way.
I think under the influence of Antidiuretic hormone (ADH), more concentrated urine is produced. Antidiuretic hormone also called vasopressin acts to maintain blood pressure, blood volume and tissue water content by controlling the amount of water and hence the concentration of urine excreted by the kidney increases. It also helps to control blood pressure by acting on the kidneys and the blood vessels.
An organized way to collect and record scientific observation using a Hypothesis
Explanation:
Hypothesis is known as initial building block in scientist method. Hypothesis is written in the form of statement. It is based on theories and knowledge. It is proposed between two variables and is mainly classified as independent and dependent hypothesis.
There are six forms of hypothesis. They are simple, complex, Empirical, Null. Altered, Logical and statistical. Relation between two variable predictions is simple hypothesis. On the other side complex hypothesis is the relationship between two or more variables.
DNA is tightly packed up to fit in the nucleus of every cell. ... Condensing DNA into chromosomes prevents DNA tangling and damage during cell division.
