Answer and Explanation:

Observing population directly gives you accurate result .

Direct observation does not need any intermediary as they themselves go for survey.

So, it is cost efficient.

Whereas indirect observing may involve manipulations.

It requires someone or many to hire who helps in surveying.

It incurs cost.

Thus, direct observation is always better than indirect observation.

Answer:

On the subjects, direct observation can be made by noticing the behaviors they possess in their natural habitat. In order to gather the information, the investigator can either hide to prevent any intrusion or can be either present physically to record the observations with the help of a camera. For example, recording or watching a chirping bird.  

On the other hand, indirect observation comprises recording of the traces left behind by the subject to comprehend the cause behind the behavior demonstrated by the subject. For example, recording the distribution of the bird droppings to determine their movement.  

Therefore, it can be concluded that direct observation helps in determining the behavior in a population and an indirect observation will assist in developing the cause behind the witnessed behaviors in the population.

Which statement is true for all sexually reproducing plants and animals? a) The process of mitosis always produces diploid cells
vazorg [7]

Answer:

d) The process of meiosis produces haploid cells

Explanation:

<em>Meiosis is a form of cell division that involves sex cells. A single diploid sex cell divides twice (meiosis I and meiosis II) to produce four haploid daughter cells. Meiosis is sometimes referred to as reductional cell division because involves halving of the chromosome number of the parent cell.</em>

When meiosis takes place in animals, the haploid cells produced can be directly referred to as gametes. However, in plants, haploid cells give rise to haploid gametophytic generations or simply gametophytes. The gametophytes eventually gives rise to gametes.

Hence, the most correct option is d.

Classify the enzyme inhibitors by giving the names, mechanisms, and effect on the kinetic parameters Km and Vmax.
V125BC [204]

Enzyme inhibitors are either competitive, uncompetitive or non-competitive inhibitors and have different effects on Km and Vmax.

<h3>What are enzyme inhibitors?</h3>

Enzyme inhibitors are substances which inhibit the catalytic activity of enzymes.

Enzyme inhibitors are classified into three:

  • Competitive inhibitors - compete with substrate for enzyme binding site. They have no effect on Vmax but increases Km.
  • Uncompetitive inhibitors- bind to the enzyme–substrate complex. They decrease both Vmax and Km.
  • Non-competitive inhibitors- bind to another site on the enzyme. They have no effect on Km but Vmax is decreased.

Therefore, the enzyme inhibitors are either competitive, uncompetitive or non-competitive inhibitors and have different effects on Km and Vmax.
