Answer:
Karyotype
Explanation:
A karyotype is a picture of all the chromosomes in an individual. These images are analyzed by geneticists to identify structural changes in the chromosomes or to identify differences in number as is the case for Down syndrome.
Karyotyping is used to identify certain genetic diseases associated with chromosomal aberrations. This is associated with the field of cytogenetics.
Answer: Hydrogen bonds are created between the base pairs in DNA. Adenine pairs with thymine and cytosine pairs with guanine. Adenine and thymine create 2 hydrogen bonds while cytosine and guanine create 3. These bonds are fairly weak so that they can be broken when DNA is replicated (by an enzyme called helicase which unwinds DNA). However despite them being weak they do stabilize DNA's double helix structure as well.
Mitosis is important<span> because it is essential for growth and repair in the </span>body<span>. </span>Mitosis<span> happens when a parent cell divides, creating two identical copies, referred to as daughter cells. During this process, it is essential that the daughter cells are exactly the same with the same copies of DNA.</span>
Answer:
population size, population density, when scientists population spacing and age structure
Explanation:
because because four characteristics is defined a population and i kind of just know.
Answer:
The wrong statement is C. <em>Individuals with Type Il survivorship exhibit high survivorship throughout
</em>
their life cycle.
Explanation:
Different species have survival curves differently shaped. In general terms, there are three different survival curves.
- Type I. Organisms do not tend to die when they are young or middle-aged, but they do when they are old. These species, in general, have a few descendants and parents provide much parental care to ensure their progeny survival. Typical of K selected species.
- Type II. Organisms that have more or less the same probabilities of dying in each age interval. These organisms can also have a few descendants and they can provide significant parental care.
- Type III. Only a few individuals survive their first period of life or their firsts years. However, the lucky ones to reach a certain age generally have a long life. These organisms have a lot of descendants at the same time, but they do not provide much parental care. Typical of r selected species.
