The image above depicts a triangular piece of land, ACD, with two roads, segments BE and CF, cutting across the property. The ow

ner wishes to add a fence along segment BC. The entire triangular piece of land is an isosceles triangle in which sides AC and CD both equal 9 miles. Segment CF represents the perpendicular bisector of the 13 mile-long base. If triangles BKC and FKE, formed from the intersection of the two roads, are congruent and segment AE is equal to side CD, what is the length of segment BC?
Select one:
A. 2.5 miles
B. 3.0 miles
C. 3.5 miles
D. 4.0 miles

What is the name for the science that studies evolution that oc-
abruzzese [7]

Answer:

D. Population genetics

Population genetics is the study of genetic variation within populations, and involves the examination and modelling of changes in the frequencies of genes and alleles in populations over space and time. ... In natural populations, however, the genetic composition of a population's gene pool may change over time.

Explanation:

microevolution - evolutionary change within a species or small group of organisms, especially over a short period. (Not studying the overall evolution in the population, just a single allele usually) Not it then

macroevolution - Macroevolution in the modern sense is evolution that is guided by selection among interspecific variation, as opposed to selection among intraspecific variation in microevolution (this goes over huge groups of different species) Not it then

gene pool - The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. (Not the study of evolution in a population) Not that then

So it has to be D

If the same base pairs are use to code for all organisms why is there so much variation among organisms
Nikitich [7]
<h2>Answer:</h2>

Because same base pairs are arranged differently among organisms due to which there are so much variations in organisms.

<h3>Explanation:</h3>
  • Variation in the organism is due to the genes.
  • Every one have different DNA/genes which describes one's features.
  • Genes are various arrangements of these four base pairs.

So same base pairs with different pattern arrangement causes variation among organism.

The forked line and probability methods make use of what probability rule?
larisa [96]

Answer:

product rule

Explanation:

In Statistics, the product rule, also called the "Leibniz law", is a rule that allows the differentiation of products from differentiable functions. This rule says that the derivative of a two-function product is the first function times the derivative of the second function plus the second function times the derivative of the first function. This rule is often used in forked line and probability methods.
