Answer:
They are called alleles.
Explanation:
Different versions of a gene are called alleles. Alleles are described as either dominant or recessive depending on their associated traits.
<h2><u>Answer:</u></h2>
Fossil: is preserved pre historic life form present under ground at high pressure for a long time.Animal die and burried under layers of sediments.
It provides evidence about the history of life on earth. It also shows different groups of organisms, including species,that have changed over time. Because the formation of any fossil depends upon the precise combination of conditions.
As the world changes, plants and animals change with time . From fossils we compare organisms of modern time with ancient , the species we see today are very different from species that lived in the past. Thus, the fossil record can be used to show that organisms changed to meet new condition.
Answer:
Explanation:
<em>Each trait of an organism is determined by discrete units called genes and individuals carry two alleles for each gene. (Mendel didn't actually discover genes though). Each gamete of an individual carries only one allele of each gene (this is Mendel's Law of Segregation).</em>
Answer:
Disruptive selection
Explanation:
According to the infographic that is attached below showing different the three main types of selection that occurs as a result of natural selection taking its course on any population, we can draw our conclusion regarding the information given to us from the question.
From the question above, it states that the finches studied by Darwin are majorly finches with either small beak or large beak which are all adapted to suit the type of food available for the finches in the islands. Whereas, finches with intermediate beaks are favored against.
According to the infographic, disruptive selection can be said to have taken place as extreme traits are favored against intermediate traits on the islands.
Hi There!
Question - Explain the cellular functions that occur when antibiotics attack a bacteria cell.
Answer - When bacteria grows to a certain limit it will not be able to divide or spread any further. (Transportation is trough the blood). The purpose of antibiotics in this case is to stop any further growth ot spreading from causing any harm to the body. In cellular functions the antibiotics used will ruin the DNA of the bacteria which will stop the growth.
Hope This Helps :)
