letter b, where the child tries to learn in speaking a second language because
this is considered to be a sensitive period in which is the period for a
development of new opportunities that a child could learn in which learning to
speak a second language is considered to be a sensitive period.
Answer:
A.
Explanation:
When we say that an individual is <u>heterozygous</u>, it means that the two alleles at the locus we are studying are different from one another. That is, each one of the parents contributed a different allele.
On the other hand, If the alleles at that locus were the same we would say the individual is <u>homozygous</u>. In other words, the two parents contributed each the same type of allele.
The DNA of the samples is isolated, and then the mapping is carried out, which is done by equipment called "DNA Sequencers". With this, it is possible to compare the genomes and conclude to whom the hair belongs.
<h3>DNA in the hair?</h3>
In the case of hair, researchers can rely on these two types of DNA (nuclear and mitochondrial). However, according to the Easy-DNA Laboratory, a hair that is cut, unfortunately, does not contain any valid DNA nucleus. However, when the hair still contains the hair bulb (hair root) it is possible to extract the nuclear DNA, because in that region we have thousands of hair forming cells (keratinocytes).
With this information, we can conclude that the DNA can be analyzed and compared, arriving at who committed the bank robbery.

Answer:
Aspirin works by inhibiting the production of prostaglandins. Aspirin inhibits the formation of prostaglandins by combining with the COX enzymes. Prostaglandins function as messenger molecules to monitor different physiological procedures in distinct regions of the body. One of the prime activities of prostaglandins is to stimulate inflammation and pain.
Prostaglandins are also the essential controller of platelet aggregation. By changing the COX enzymes inside the platelets, aspirin makes platelets to lose the stickiness, which is required to instigate clotting of blood.
There are two forms of cyclooxygenase, that is, COX-1 and COX-2. COX-1 generates prostaglandins and COX-2 mediates pain and swelling in response to tissue injury. Aspirin prevents both COX-1 and COX-2 functioning, while COX-2 is the therapeutic target of the drug.
However, it is the association of aspirin with COX-1 in the gastrointestinal tract, which results in the unwanted side effects of the drug. COX-1 is required to sustain a thick lining of the stomach. As aspirin inhibits the COX-1 enzyme, thus, the continuous use of the drug can result in the thinning of mucus, which safeguards the stomach from gastric juices.
In such cases, stomach bleeding, ulcers, and in certain situations perforation of the stomach can take place. Therefore, aspirin exhibits both bad and good effects.
The muscles of our lungs, stomach, and intestines are made of smooth muscle tissue. There are three types of tissue. Skeletal, cardiac and smooth.
