Waxes are considered to be important to living things, because waxes are a type of lipid. Lipids are energy stored within our body, somewhat like a storage of energy. Lipids, consists of other substances, such as oil, fats and the likes. Lipids store energy, for the cells to consume whenever they need it.
<u>Answer</u>: Natural selection.
<u>Explanation</u>:
- The concept of <em>natural selection</em> was given by <em>Charles Darwin.</em>
- According to this concept, in a given environment the organisms that possess <em>better adaptations</em> have<em> higher chances of survival</em> and, leave behind a <em>greater number of progenies</em>.
- When malaria outbreak occurs, the allele frequencies change and only the organisms that possess the alleles which help them to <em>survive</em> this outbreak due to resistance against malarial infection will be selected by nature and<em> hence, this is an example of natural selection.</em>
Answer:
- The Island population likely has fewer alleles-that is versions of genes-than the mainland population.
A- Agree <u>B- Disagree</u>
- Genetic drift is more pronounced in the island population than in the mainland population in these first few generations
A- Agree <u>B- Disagree</u>
- Some harmful traits may have become more common in the island population than in the mainland population
<u>A- Agree</u>- B- Disagree
- Biologist observed genetic drift but not evolution
<u>A- Agree</u> B- Disagree
Explanation:
If there was genetic drift, then allele frequency either increased or decreased by chance, irrespective of natural selection that is irrespective to weather those alleles helped individuals survive in the island environment. In molecular genetic data, there are statistical signature in the population variation that indicate weather selection or other processes occurred.
Answer:
I wasn't quite sure what virus you were referring to in your question, but here's a general answer: Viruses use their host cells' machinery to replicate themselves.
If they are a specific type of virus known as a retrovirus, they have the ability to use the host cells' enzymes to change the RNA contained within the virus into DNA (via some type of replication I suppose).
In other cases, if they contain DNA instead of RNA (that is, the virus), they can use the host cell's machinery to create RNA via enzymes involved in transcription and/or they can incorporate that DNA into the host cell's DNA. This is part of a type of viral replication cycle known as the lysogenic cycle.
In another type of viral replication cycle known as the lytic cycle, the virus simply has itself and its genome duplicated until the host cell bursts, releasing the viral material. Here, again, the virus uses the host cell's machinery to replicate itself.
• Skeletal and limb abnormalities
• Central nervous system alterations
• Heart defects
These are applicable in examples to many drugs that reach the developing fetus or embryo can cause death or congenital defects.
<h3>What is meant by congenital defects?</h3>
- A congenital anomaly is a morphological or functional abnormality that appears during intrauterine life.
- These illnesses, which are also known as birth defects, congenital disorders, or congenital abnormalities, arise during pregnancy and can be detected before or at birth as well as later in life.
<h3>What kinds of flaws are instances of congenital?</h3>
- Cleft lip and palate are typically discovered during standard prenatal screenings.
- congenital heart disease, which might include a hole in the heart, a valve issue, or a blood vessel issue.
- Usually identified in the first few years of life, cerebral palsy.
<h3>Each of the medications or drug classes listed below has the potential to give birth to abnormalities in an unborn child:</h3>
- ACE inhibitors (angiotensin converting enzyme).
- antagonist of angiotensin II.
- alcohol
- cocaine
- isotretinoin (an acne medication) (an acne drug)
- high vitamin A dosages.
