The correct answer is D.  In order for recessive trait to be expressed in the phenotype of the offspring, it must receive a recessive allele from each parent, making it homozygous for the recessive gene.

Answer:

D

Explanation:

Answer:

Referring to the attached figure, there are two alleles V and v for height. The reason for using capital and small letters is to indicate the dominant or recessive nature of the allele.

Explanation:

Dominant (V):

An allele that is dominant means only one copy of that allele is enough for the expression of trait. For example, if V is for tall height, an individual with genotype Vv or VV both will have tall height because they have the allele of tall height that is dominant in nature.

Recessie(v):

An allele that is recessive nature means two copies of that allele are mandatory  for the expression of trait. For example, if v is for short height, an individual with genotype vv will have short height because they have two copies of same alleles that are recessive in nature. However if the genotype is Vv, still the individual will have tall height because capital letter is masking the effect of small letter (v allele). This is because of recessive nature of allele.

Hope it help!

In genetics, the first letter of the dominant trait is used to denote genes, with uppercase and lowercase letters used to represent dominant and recessive alleles, respectively. This makes it easier to predict inheritance patterns across generations. For instance, in the case of a pea plant, we would denote the genotype of a homozygous dominant plant with violet flowers as VV, a heterozygote as Vv, and a homozygous recessive plant as vv.

In genetics, we follow several conventions to designate genes and their alleles. To illustrate, we use the first letter of the corresponding dominant trait to denote a gene. For example, if violet is the dominant color trait for a pea plant's flower, the gene's shorthand would be a V.

When it comes to allelic representation, we use uppercase and lowercase letters to differentiate dominant and recessive alleles, with uppercase denoting the dominant allele and lowercase indicating the recessive one. As a result, we'd denote the genotype of a homozygous dominant pea plant with violet flowers as VV, a heterozygote with violet flowers as Vv, and a homozygous recessive plant with white flowers as vv.

This convention makes it more manageable and efficient to depict and predict inheritance patterns of different traits across generations. For instance, by simply looking at the capitalized or lowercase letters, one can quickly discern whether a given plant is homozygous or heterozygous for a specific trait and whether it displays the dominant or recessive phenotype.

Many factors affect water quality

Sedimentation.

Runoff.

Erosion.

Dissolved oxygen.

pH.

Temperature.

Decayed organic materials.

Pesticides.

Water quality is affected by natural events and human-induced factors such as runoff from agriculture, pollutants from urban and industrial waste, and overuse of nitrogen and pesticides, leading to contamination and ecosystem imbalances. Regular monitoring and adherence to laws like the Clean Water Act are vital for maintaining water quality.

Water quality is influenced by a variety of factors, both natural and anthropogenic. Natural events such as storms, volcanic eruptions, and earthquakes can cause fluctuations in water quality. However, human activities have a more significant impact, leading to water pollution through the introduction of pathogenic organisms, chemical pollutants, and nutrient runoff, which in turn can cause issues such as algal blooms and oxygen depletion in water bodies.

Human settlement often contributes to water pollution, with common pollutants including untreated sewage, various chemicals, radioactive waste, and heat. Agricultural practices that involve heavy use of nitrogen and pesticides can lead to these substances entering the water supply, which can then accumulate in the aquatic food web, ultimately affecting human health. It is crucial for water management policies, such as the Clean Water Act enforced by the EPA, to address these issues by establishing standards and conducting regular monitoring of water quality indicators like pH, conductivity, temperature, and bacteria levels.

In summary, the deterioration of water quality can result from changes in water sources, such as aquifers, or through modifications in the physical infrastructure, like wells. To mitigate pollution, water quality testing and monitoring are essential, and compliance with environmental laws is necessary to ensure a safe water supply for consumption and support of ecosystems.

The Answer is B - A cell's genotype is determined by its DNA, and it's phenotype is determined by its proteins.

Hope this helps!  

The correct answer is option B.The correct statement is that a cell's phenotype is determined by its proteins, which are encoded by the genes within the DNA, forming the cell's genotype. The genotype consists of the collection of genes, while the phenotype is the expression of these genes as proteins under specific environmental conditions.

The true statement from the given options is: A cell's genotype is determined by its DNA, and it's phenotype is determined by its proteins. This is because the genotype refers to the full collection of genes that a cell contains, which are sections of DNA that encode for proteins. However, the phenotype of a cell is the result of the observable characteristics and traits which are produced by the expression of these genes into proteins acting within specific environmental conditions.

DNA is the carrier of genetic information and it specifies the sequence of messenger RNA (mRNA), which in turn, guides the amino acid sequence of proteins following the central dogma of molecular biology. It is the sequence and expression of these proteins that give rise to the phenotype, which can vary according to which genes are expressed at a particular time and the cell's environment.

Answer:

the thyroid gland is a butterfly shaped organ at the base of your neck that controls growth, hormones, metabolism, and development.

The answer is; a loss in biodiversity due to the replanting of the same modified crops each year

Monoculture has a drastic effect on biodiversity. Monoculture reduces the genetic diversity in a region and hence the environment is unable to maintain itself. This makes the environment less adaptable to environmental changes since natural selection acts on genetic diversity. Biodiversity is also important for living communities because it provides critical ecosystem services and resources critical for life, such as nutrient cycling.

Given,

The mass of phosphorus is 8.2 g,

The mass of hydrogen is 4 g,

The molar mass of P₄ is 123.6 g/mol

The molar mass of H₂ is 2.016 g/mol

The molar mass of PH₃ is 33.924 g/mol

The balanced chemical reaction is:

P₄ (s) + 6H₂ (g) → 4PH₃ (g)

First, there is a need to calculate the moles of P₄ and H₂,

Moles of P₄ = mass of P₄/molar mass of P₄ = 8.2 g / 123.6 g/mol

= 0.066 moles

Moles of H₂ = mass of H₂/molar mass of H₂ = 4 g / 2.016 g/mol

= 1.98 moles

From the reaction it is concluded that:

1 mol of P₄ reacts with 6 moles of H₂

0.066 moles of P₄ reacts with 6 × 0.066 = 0.396 moles of H₂.

This signifies that H₂ is in excess amount and P₄ is in limited amount.

Now, there is a need to calculate the moles of PH₃:

As, 1 mole of P₄ reacts to give 4 moles of PH₃

So, 0.066 moles of P₄ reacts to give 4 × 0.066 = 0.264 moles of PH₃.

Now, there is a need to calculate the mass of PH₃

Mass of PH₃ = moles of PH₃ × molar mass of PH₃

Mass of PH₃ = 0.264 moles × 33.924 g/mol = 8.955 g

Therefore, the maximum number of grams of PH₃ formed is 8.955 g.
