What happens to the temperature of a liquid as it evaporates?

Which will experience greater acceleration ?

son4ous [18]

Answer:

C

Explanation:

According to Newton's second law, when the same force is applied to two objects of different masses, a. the object with greater mass will experience a great acceleration and the object with less mass will experience an even greater acceleration.

A scientist performs an experiment to see if acids have an effect on the health of a particular type of plant. Three sets of pla

olga55 [171]

The question is not complete but it can be answered in general as the plants cannot survive in acidic conditions.

Answer: High acidity is harmful to this type of plant.

Explanation:

The plants that were kept in the higher acidic conditions are less likely to grow in higher acidic conditions.

The plants that were kept in more basic conditions will also not grow properly as the pH of the soil should be neutral, slightly acidic or slightly basic.

The plants that was kept as a control on the pH of 7 will grow the best as the pH is optimum for the growth of the plants.

The conclusion is high acidity is harmful for the life of the plants.

a. biological pest control

biological pest control is when other plants or animals are used to control pests. There are no chemicals used only the natural roles of the environment.

Hope this helped!

A plant contains the alleles Gg for green pod

Viefleur [7K]

Given:

Allele for green pod colour = Gg (Heterozygous)

Allele for Yellow pod colour = gg (Homozygous)

Explanation:

Parents: Gg x gg

When this two parent are crossed, it leads to the following F1 generation (off springs):

• Gg (green colour pod)

• Gg (Green colour pod)

• gg (Yellow colour pod)

Form the produced offspring it can be inferred that the allele combination for green colour pod is Gg. Among the four off springs obtained 2/4 are green colour pod and 2/4 are yellow colour pod.

The curly toe phenotype is controlled by 4 genes that act in an additive manner. The environment does not have an effect on this

Sergio [31]

Answer:

What is the highest number of risk units an individual can have with this model? 48 units of risk
What is the phenotype of an individual of genotype AaBbCCDd? The individual has curly toes
Is it possible for them to have a child with curly toes?

Yes, the couple can have children with curly toes.

Explanation:

Available data:

The curly toe phenotype is controlled by 4 diallelic additive genes
Genes A, B, C, D
A dominant allele has 6 units of risk
A recessive allele has 2 units of risk
Individuals with more than 35 units of risk have curly toes
Individuals with 35 or fewer risk units have straight toes

The term quantitative heritability refers to the transmission of a phenotypic trait in which expression depends on the additive effect of a series of genes.

Polygenic heritability occurs when a trait results from the interaction of more than one gene. And these genes can also have more than two alleles. The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.

Quantitative traits are those that can be measure, such as longitude, weight, eggs laid per female, among others. These characters do not group individuals by any precise and clear categories. Instead, they group individuals in many different categories that depend on how the genes were intercrossed and distributed during meiosis. The result depends on the magnitude in which each allele contributes to the final phenotype and genotype. When they interact, they create a gradation in phenotypes, according to the level of contribution.

According to this information, and knowing how each allele contributes to the risk, we can say that the minimum units of risk are 16, determined by the recessive genotype aabbccdd. Each recessive allele contributes with 2 units of risk, so (aa=4units + bb=4 units + cc=4 units + dd=4 units) = 16 units.

Each time a dominant allele is present in the genotype, it adds 6 units to the total risk.

What is the highest number of risk units an individual can have with this model?

48 units of risk, which corresponds to the genotype AABBCCDD. Each dominant allele contributes 6 units to the risk. There are 8 dominant alleles, so, 8x6=48 units.

What is the phenotype of an individual of genotype AaBbCCDd?

The individual has curly toes because it has a risk of 36 units, which is superior to the limit of 35 units. Dominant alleles A, B, C, C, D contribute with 30 units of risk (6x5), and recessive alleles a, b, d contribute 6 units of risk (3x2).

F1) 16 /32 = 1/2 individuals in the progeny are expected to have curly toes

16 /32 = 1/2 individuals are expected to have straight toes

Is it possible for them to have a child with curly toes?

Yes, the couple can have children with curly toes.

To have curly toes, individuals must have more than 35 units of risk.

To have more than 35 units, individuals´ genotypes must carry at least 5 dominant alleles (which equal 30 units).
