The answer would be B. Females cannot inherit them because they have 2 X chromosomes, and no Y chromosome

Y linked diseases can't be inherited by females. This is because females have xx chromosomes while males have xy. Because if this, only males can inherit diseases linked with the y chromosome.

Which of the following statements best explains how elements can be distinguished from molecules and compounds?

Aleks [24]

Answer: Option (b) is the correct answer.

Explanation:

A compound is defined as the substance in which different elements are chemically combined together in a fixed ratio by mass.

For example, $MgSO_{4}$ is a compound and elements are present in 1:4 ratio.

A compound can be divided into its constituent or simpler substances.

On the other hand, a molecule is defined as a specie that contains same type of elements.

For example, $O_{2}$ is an oxygen molecule.

And, an element is defined as a substance which is made up of only one type of atoms. An element can never be broken down into its constituent particles.

For example, a piece of lithium metal will contain atoms of lithium only.

Thus, we can conclude that the statement elements are made up of one kind of atom best explains how elements can be distinguished from molecules and compounds.

Describe how an organism's genotypes codes for their phenotype. In your answer use the vocabulary terms: Phenotype, genotype, DN

Lemur [1.5K]

Answer:

The organism's genotype encodes their phenotype because the genotype corresponds to the characteristic that is determined by genes —formed by fragments of DNA— which are transcribed into mRNA to be translated into amino acid sequences in the synthesis of proteins, determining the morphological and functional characteristics of an organism, that is, its phenotype.

Explanation:

Genotype corresponds to the genetic information contained in the DNA, according to the sequence of nucleotides in its molecular structure. This genotype includes characteristics or polymorphisms that define the appearance and function of living beings.

Each DNA molecule constitutes a chromosome, formed by genes —DNA fragments— each of which determines specific characteristics.

When DNA is transcribed into mRNA, information is being sent that is necessary for the incorporation of amino acids into a protein that is being synthesized. The proteins, in turn, determine morphological and functional characteristics that constitute the phenotype of an individual.

4. If a reaction took 2 minutes and 30 seconds to complete. What rate would you report?

Arturiano [62]

Reaction rate is calculated using the formula rate = Δ[C]/Δt, where Δ[C] is the change in product concentration during time period Δt. The rate of reaction can be observed by watching the disappearance of a reactant or the appearance of a product over time.

Weegy 2. slight differences in inherited traits, such as feather color in birds, are called

Alla [95]

The right option is a. variations.

Variations are the differences between the individual organisms of the same species which is as a result of genetic differences or the influence of environmental factors on the expression of the genetic abilities. Variation may be expressed in behavior, physical appearance, learning, and metabolism. The two types of variations are somatic variation and germinal variation.
