Answer:

C.) crystalline solids

Explanation:

The solid materials may be crystalline or amorphous. The concept of crystal structure is related to the organization of atoms in a geometrical form. Crystalline structures are present in various materials, where atoms distributed within their structure form a network called the crystalline lattice. Therefore, crystalline structures have salts, metals and most minerals. Crystalline structures are formed by unit cells that are their basic unit, as they constitute the smallest set of associated atoms found in a crystalline structure.

The molecules of the crystalline structures can have two types of bonds, the directional ones, which include the covalent and dipole dipole and the non-directional ones where the metallic, ionic, van der Walls bonds. When formed by ionic compounds, these crystalline structures can result in crystalline solids.

1. In a population of 200 field mice, 98 mice are homozygous dominant for brown fur (FF), 84 mice are heterozygous (Ff), and 18

iVinArrow [24]

A.
The genotype frequencies can be determined by dividing the number of individuals with a genotype by the total number all the individuals.
FF genotype frequency:
98÷200=0,49. There are approximately 5 homozygous dominant mice in 10.
Ff genotype frequency:
84÷200=0,42. There are approximately 4 heterozygous mice in 10.
ff genotype frequency:
18÷200=0,09. There are approximately 1 homozygous recessive mouse in 10.

B.
To determine the frequency of an allele we can divide the number of times that the allele appears by the total number of alleles.
F allele frequency:
 $\frac{(98*2)+84}{400}$ =0.7
There are 7 F alleles in 10 random alleles.
f allele frequency:
$\frac{84+(18*2)}{400}$ =0.3
There are 3 f alleles in 10 random alleles.

Read the passage. What is the claim?

malfutka [58]

Answer:

Hello There. the Correct answer to this is This drug helps people lose more weight than diet and exercise alone. The reason for this statement is that with diet and exercise alone, 23% lost weight whereas with diet, exercise and the drug, 48% lost weight so the conclusion is that the drug enhanced weight loss. As a personal comment, the trouble with synthetic drugs is that there are usually side effects so that avoiding the drugs also avoids side effects so therefore I think it is best to find the right diet and exercise that actually lowers weight or take a vitamin or herb supplement to help with this.

Hope it helps!
