The homozygous dominant genotype will show all dominant offspring in test cross.

To as certain whether or not the dominant trait is heterozygous, a text cross between a person expressing a recessive trait and one exhibiting a dominant trait is performed. An individual expressing a dominant trait could have two copies of the dominant allele (homozygous dominant) or one copy of each dominant and recessive allele, according to the law of dominance in genetics (heterozygous dominant). A test cross can be used to ascertain whether a person is homozygous dominant or heterozygous dominant. An individual is bred with another who is homozygous for the recessive trait in a test cross, and the children of the test cross are then evaluated. The allele that the homozygous recessive person passes on determines the phenotype of the progeny because they can only transmit recessive alleles. Thus, this test has two potential outcomes:

Hence, test cross is used to determine genotype of offspring.

Based on Mary's observation that the five similar plants she planted in the same soil grew more slowly each year, a hypothesis could be that the soil's nutrient content became progressively depleted over time.

The hypothesis suggests that the plants' growth rate decreased because the soil lacked sufficient nutrients necessary for optimal growth.

Over the years, as the plants extracted nutrients from the soil, they were not replenished adequately, leading to a gradual decline in nutrient availability. This nutrient depletion hypothesis assumes that the soil's initial nutrient composition was sufficient to support the plants' growth but became insufficient over time.

To test this hypothesis, Mary could conduct soil tests to measure nutrient levels, both initially and after each year of growth. Comparing nutrient concentrations with the growth rates of the plants would provide evidence to support or refute the hypothesis. Mary could consider other factors such as soil pH, water availability, or pest infestations, which could also contribute to the observed decrease in plant growth rate over time.

Using a testcross, geneticists can analyze gene recombination by crossing an individual that is homozygous for the recessive alleles of two genes with a doubly heterozygous individual.

Each gene in each of us has two alleles, or variations. You are considered to be homozygous for a gene if you have two identical copies of it. In contrast, a genotype with heterozygosity has different alleles. Everyone who has a recessive trait, like red hair or blue eyes, is homozygous for that particular gene. A scientist can perform a test cross to establish if an organism exhibiting a dominant trait is homozygous or heterozygous for a specific allele.

A set of gene variants known as a dominant genotype have dominant alleles that, in circumstances of total dominance, prevent heterozygous people from expressing recessive alleles.

Explanation:

leading strand is the new DNA formed after replication. lagging strand is the old DNA strand

A chelating agent is required because it attracts and traps metal ions, which are cofactors in enzyme processes. If they were not removed from the solution, they would catalyse processes that would destroy the DNA, similar to DNAase devouring DNA.

Chelation is a sort of bonding that occurs between ions and molecules and metal ions. The creation or existence of two or more distinct coordinate bonds between a polydentate (many bound) ligand and a single central metal atom is required.

Chelants, chelators, chelating agents, and sequestering agents are all names for these ligands. They are often organic molecules, however this is not always the case, as with zinc and its usage as a maintenance treatment to limit copper absorption in persons with Wilson's disease.

Answer:

5.7 m/s     

Explanation:

The computation of Sheila 's velocity right after she gets thrown out of the bike is shown below:

1) The Physical principle: conservation of momentum.

If there is no net external force operating on a system, so the system's total momentum is conserved

The momentum, p, is a vector magnitude that is determined as the product of the mass by the velocity:

P = mv.

2) Taking into account therefore that there is no net force on the device, Sheila and the momentum of the bike are the identical pre and post collision.

Based on this, the calculation is as follows

Momentum before the collision:

       \(P_1 = (mass\ of\ Sheila + mass\ of\ the\ bike) \times velocity\)

       \(P_1 = (60kg + m) \times v_1\)

= 340 kg m/s

Now Momentum after the collision:

      \(P_2 = mass\ of\ sheila \times velocity\ of\ Sheila + mass\ of\ the\ bike \times velocity\ of\ the\ bike\)

\(P_2 = 60kg \times v_2 + m \times 0 = 60kg \times v_2\)

\(P_1 = P_2\)

\(= (60kg + m) \times v_1\)

\(= 60kg \times v_2\)

\(= 340 kg .\ m/s\)

\(= 60kg \times v_2\)

\(v_2 = \frac{340\ kg .\ m/s }{60\ kg}\)

= 5.7 m/s     

The velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.

The given parameters;

The velocity of Sheila immediately after she is thrown from the bike is calculated as follows;

P = mv

where;

v is the velocity Sheila

\(v = \frac{P}{m} \\\\v = \frac{340}{60} \\\\v = 5.67 \ m/s\)

Thus, the velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.

Answer:

30 calories of energy

Explanation:

In an aquatic ecosystem, zooplanktons are primary consumer i.e. they feed on primary producers e.g phytoplanktons. They are fed on by smaller fishes e.g tilapia, which in turn is fed on by sharks. Based on this, we have a food chain as follows:

phytoplankton → zooplankton → tilapia fish → shark

From this food chain, it appears that ZOOPLANKTON is a primary consumer while SHARK is a tertiary consumer. Since only about 10% of energy is transferred to each trophic level when organisms feed on one another, if there are 3000 calories of energy available at the zooplankton, the following will be available for sharks:

For secondary consumer = 10/100 × 3000 = 300 calories for tilapia fish

For tertiary consumer = 10/100 × 300 = 30 calories for shark.

Explanation:

Answer:

Explanation:

Phenotypes that Mendel studied was controlled by one gene that had two possible alleles, dominant and recessive allele. This made it possible to see just one or the other phenotype (total of 2 phenotypes).

Well now we know that a characteristic may be controlled by one gene with two alleles, but the two alleles may not have a traditional relationship of dominant and recessive. Which is why we see the patterns like codominance and incomplete dominance.

Codominance is when both alleles are expressed equally in the phenotype of the heterozygote. For example, you have a black flower and red flower, a codominant flower would have both black petals and red petals. Do you see how the traditional relationship of one being dominant and other being recessive no longer holds because you express both alleles.

Incomplete dominance occurs when the phenotype of the offspring is somewhere in between the phenotype of both parents. SO a black and red flower would make an offspring with purple petals where neither of the alleles reigns supreme over other rather we get a mixture of both alleles.

The passing of the alleles from the parent to the offspring in a particular manner was given by Mendel, he defined the passing of the recessive and the dominant allele in a specific way from generations.

Mendelian inheritance does not apply to incomplete and co-dominance.

Therefore, the Mendelian inheritance law does not apply to incomplete dominance and co-dominance.

Mitosis in a process where a cell is devided, resulting in two identical daughter cells.

Proteins produced by free ribosomes enter the cells cytosol, where they are rapidly subjected to post-translational modifications. These modifications include glycosylation, proteolytic cleavage and acetylation.

Whereas these proteins are responsible for the normal functioning of the cell, those produced by bound ribosomes are involved in a variety of functions. Bound ribosomes synthesize proteins associated with the endoplasmic reticulum, such as enzymes and structural proteins.

These proteins are subject to further modifications before being shipped out of the endoplasmic reticulum into other organelles such as the Golgi apparatus, lysosomes, and secretory vesicles.

From there the proteins are exported from the cell for use in the external environment, such as hormones, enzymes, and toxins. When the proteins are no longer need they are broken down by lysosomal enzymes and recycled for other uses.
