What does it mean to say B is representing the dominant gene

Chemistry

1 answer:

Degger [83]2 years ago

8 0

Answer:

Dominant genes are always represented by a capital letter which in this case is the letter B whereas recessive genes will be represented by a lower case letter like b.

You only need one copy of a dominant gene or allele to inherit it. A dominant allele is always expressed even if only one copy is present.

But you need two copies of genes or alleles to inherit the recessive gene. There also can't be a dominant allele of the gene if you are to inherit this.

Metals react with oxygen to give oxides with the general formula MxOy. What is a balanced chemical equation for the reaction of

katovenus [111]

Answer: $4Fe+3O_2\rightarrow 2Fe_2O_3$

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here iron is having an oxidation state of +3 called as $Fe^{3+}$ cation and oxide $O^{2-}$ is an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral $Fe_2O_3$ .

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Calculate the amount of ATP in kg that is turned over by a resting human every 24 hours. Assume that a typical human contains ~5

valentinak56 [21]

Answer:

The correct answer is 66.35 kilograms.

Explanation:

Based on the data given in the question, the energy consumed by the body of a human being is 50%. Based on the given data, the energy consumed in a day is 8000 kJ, 50 percent is the energy transfer efficiency. Thus, the consumption of total energy is 4000 kJ, and for the transformation of ADP to ATP, the energy involved is 30.6 kJ per mole.

Hence, the total ATP produced in the process is,

ATP = 4000 kJ / 30.6 kJ/mol

= 130.7189 mol.

Thus, with the energy transfer efficiency of 50 percent, the total moles of ATP produced is 130.7 mol.

The mass of ATP can be calculated by using the formula,

moles = mass/molecular mass

The molecular mass of ATP is 507.18 g per mol

Now by putting the values we get,

mass of ATP = 130.7189 mol * 507.18 g/mol

= 66298.011 g or 66.298 kg

It is mentioned that human comprise 50 g of ATP or 0.05 kg of ATP. Therefore, the sum of the available ATP will be.

= Total production of ATP + Total ATP available

= 66.298 kg + 0.05 kg

= 66.348 kg

Hence, the sum of the ATP that is turned over by a resting human in a day is 66.35 kg.

Potential energy due to the position of an object above earth surface is called

KengaRu [80]

ANSWER:

Potential energy due to the position of an object above Earth's surface is called gravitational potential energy.

EXPLANATION:

Gravitational energy is the potential energy compared with gravitational force, as work is needed to further things against Earth’s gravity. The potential energy due to high positions is called gravitational potential energy, and is evidenced by water in an elevated storage or kept behind a dam. If an article falls from one point to different point inside a gravitational field, the force of gravitation will do actual work on the object, and the gravitational potential energy will decrease by the same amount.
