Answer:

Option C, single-blind study

Explanation:

In a single blind study, the researcher is aware of the experimental group in which the subject is placed. However, the subject is unaware of its placement. Such kinds of experiments are conducted to reduce the risk of errors or variation in participant’s response, if they come to know the group type in which they are placed.  

In a double blind study both the researcher and the subject of the experiment are unaware of the groups in which the subject is placed while conducting the experiment

Hence, option C is correct

Electricity is added to recharge a battery. What is added to ADP to form ATP?
White raven [17]

Electricity is added to recharge a battery. A third phosphate group  is added to ADP to form ATP.

ATP or Adenosine triphosphate contains adenine, ribose and 3 phosphate groups.

ADP is converted to ATP by the following reaction:

ADP+Pi+energy⇄ATP

The analogy between battery and ATP can be explained as ATP is higher energy form and ADP is lower energy form like charged and uncharged form of the battery. When the terminal or third phosphate is removed from the ATP it becomes ADP and releases energy like a battery. The additional phosphate group when added to ADP forms the ATP molecule like the energy spent by the batteries are recharged by putting in additional energy. Here the additional energy is provided by the third phosphate group.

Given a population that contains genetic variation, what is the correct sequence of the following events under the influence of
natali 33 [55]

The correct option is (a) 2 → 4 → 1 → 3

A change occurs in the environment. → Poorly adapted individuals have decreased survivorship. → Well-adapted individuals leave more offspring than do poorly adapted individuals. → Genetic frequencies within the population change.

<h3>What is genetic variation in population?</h3>
  • The presence of various alleles, or different gene versions, within a population indicates genetic variety.
  • If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
  • Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.
