Biology
1 answer:
Umnica [9.8K]3 years ago

Answer:

Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others. It turns out that although viruses can attack living organisms, cause diseases, and even reproduce, they do not meet the criteria that biologists use to define life. Consequently, virologists are not biologists, strictly speaking. Similarly, some biologists study the early molecular evolution that gave rise to life; since the events that preceded life are not biological events, these scientists are also excluded from biology in the strict sense of the term.

<h3>What is Chvostek sign?</h3>

The aberrant twitching of muscles that are stimulated (innervated) by the facial nerve  (also known as Cranial Nerve Seven, or CNVII) is known as the Chvostek sign.

The facial muscles on the same side of the face will occasionally contract when the facial nerve is touched in front of the ear (called ipsilateral facial spasm). Frequently, the muscles that regulate the nose, lips, and brows will spasm.

What type of chlorophyll does the reaction center contain
LuckyWell [14K]

Answer:

Chlorophyll "a"

Explanation:

The reaction centers of the photosystem have chlorophyll "a" molecules. The chlorophyll "a" that functions as a reaction center for the photosystem II has absorption maxima at 680 nm and therefore, it is called P680. The reaction center of photosystem I also have chlorophyll "a" molecules that have the absorption peak at 700 nm. The chlorophyll "a" molecules serving as reaction centers transfer the photoexcited electrons to a primary acceptor during the light-dependent phase of photosynthesis.

Which of the following is not being undertaken to reduce the risks to human health from pesticides?
Andru [333]

<span>Pesticide use is harmful to human agriculture because it contains an antifreezing chemical (present in transportation vehicles). When the chemical seeps into the leaves of the plant, it is distributed all over its body and remains there. The chemical may still be present there when we are going to the plant.</span>
