Answer:

The behaviour of molecules in different phases of matter represents a balance between the kinetic energies of the molecules and the attractive forces between them. All molecules are attracted to each other. ... The molecules are in the solid state. At higher temperatures, the kinetic energy of the molecules is higher.

In guinea pigs, dark hair (D) is dominant over light hair (d) and curly hair (C) is dominant over smooth hair (c). Complete a di

1. The Punnett square should be laid down in a table of two entries. On the top entry, the possible alleles of one of the parents, and on the other entry, the possible alleles of the other parent, which will be the same as both have the same genotype. The possible alleles for both parents would be: DC, Dc, dC, and dc. On the actual table's body, all alleles should be crossed from one entry and the other obtaining the possible genotypes of the offspring and their proportions, and, therefore, the possible phenotypes and their proportions.

2. By the Punnett square (attached is an example of it), we are able to identify that all possible genotypes have a 1/8 likelihood to happen, besides the genotypes that are homozygous for both alleles (whether dominant or recessive on both traits, or dominant on one trait and recessive on the other) which have a 1/16 likelihood to happen, and those that are equal to the parents (dihybrid) with a 1/4 likelihood to happen.
DDCC, 1/16; DDCc, 1/8; DdCC, 1/8; DDcc, 1/16; DdCc, 1/4; Ddcc, 1/8; ddCC, 1/16; ddCc, 1/8; ddcc, 1/16.

3. Dark and curly hair corresponds to 9/16 of all the offspring. These traits are dominant, and, therefore, are the ones that are present depending solely on the presence of one dominant allele on each trait.
Dark and smooth hair have a likelihood of 3/16 - all those that are homozygous recessive for smooth hair but still have, at least, one dominant allele for dark hair.
Light and curly hair have a likelihood of 3/16 - all those that are homozygous recessive for light hair but still have, at least, one dominant allele for curly hair.
Light and smooth hair have a 1/16 likelihood to occur, which corresponds to the only possible full homozygous recessive genotype.

What is the difference between arbitrary and natural levels? Why do these matter? (4) how do archaeologists recover the smallest

Vlada [557]

Arbitrary level refers to the fundamental vertical subdivision of an excavation square, implied only when easily identifiable natural strata are absent and when natural strata are more than ten centimeters thick.

Natural strata refer to a vertical subdivision of an excavation square, which is reliant on the natural breaks in the sediments in terms of grain size, color, hardness, texture, or other features.

It is important to know the difference between the arbitrary and natural levels as arbitrary levels could amalgamate artifacts from distinct natural levels, that is, of distinct geologic contexts.

The archaeologists can recover the smallest ecofacts and artifacts with the assistance of flotation, screening, and bulk matrix processing

In a population of birds, the average beak size is favored. What type of selection is this?

alexira [117]

Answer:

C. Stabilizing selection

Explanation:

Natural selection, is of three different types namely: disruptive selection, directional selection and stabilizing selection. Disruptive selection occurs when the two extremes of a population are being favored over the average or intermediate.

Directional occurs when one extreme of a population is favored. However, in STABILIZING SELECTION, the average or intermediate population is favored over both extremes of a population. Example is when the average-sized beaks of a bird population is being favored over the long and short ones (extremes).
