Answer – Absolute Dating

In order to determine the absolute age (otherwise called the actual age) of a rock layer, Geologists make use of a technique known as absolute dating. This technique is performed by assessing the nuclear decay of radioactive isotopes, a phenomenon that behaves in a clock-like manner.

Which of the following is an autotroph? a. mushroom b. tree c. deer d. wolf
aliina [53]

The right answer is b. Tree.

Some plants (like trees) have evolved with different unusual nutritional adaptations over time. Heterotrophic plants are plants that use only or partly a source of organic carbon to grow, unlike the most common autotrophic plants, which use inorganic carbon and water to grow, often through the process of photosynthesis (photoautotrophic).

In Drosophila, a very prolific phenotypically normal female was crossed to a phenotypically normal male. All of the female offsp
erastova [34]

Answer:

22 mu

Explanation:

Since maximum number of flies are observed with +pb and s++ phenotype, they are the parental combinations.

Minimum number of flies are observed with +p+ and s+b phenotype hence they are the result of double crossover.

Gene order would be +bp and s++ since it is the only case which would lead to production of above mentioned double crossover. Hence gene b is in the middle of genes s and p.

Single cross over between genes s and b will give progeny +++ and sbp.

Map distance between s and b loci = recombination frequency =

(number of recombinants/ total progeny)*100

= [(single cross over between s and b + double crossover)/total progeny]*100

= [(102+106+7+5/1000]*100

=(220/1000)*100

=0.22*100

=22 mu

A client undergoing a skin test has been intradermally injected with a disease-specific antigen on the inner forearm. The client
yarga [219]

Answer:

Yes, there is a need to assure the client that this is a normal reaction.

Explanation:

In the given case, it is the duty of a nurse to assure the patient that swelling takes place while performing intradermal vaccination. As with the administration of disease-specific antigens, the injected area inflames that generally takes place due to the development of antibodies against the presented antigens.  

Thus, both the patient and the nurse need to be calm in such a situation and should leave the swelling open so that it can get heal by itself. In case, if one applies ice packs or rubs the affected area, it can enhance the condition and may result in more issues.
