The change in internal energy of this gas sample is equal to: c. 715 J.

<u>Given the following data:</u>

  • Quantity of heat = 874 J.
  • Work done = 159 J.

<h3>What is the First Law of Thermodynamics?</h3>

Mathematically, the the First Law of Thermodynamics is given by this formula:

\Delta H = Q-W

Where;

  • \Delta H is the change in internal energy.
  • Q is the quantity of heat.
  • W is the work done.

Substituting the parameters into the formula, we have;

\Delta H =874-159\\\\\Delta H = 715

Change in internal energy (ΔH) = 715 Joules.

Why should damage be repaired before a cell enters mitosis​
a_sh-v [17]

Answer:

Cells do not repair damage to DNA during mitosis because telomeres could fuse together. ... Throughout a cell's life, corrective mechanisms act to repair DNA strand breaks. The exception is during the critical moment of cell division, when chromosomes are most vulnerable.

How the combination of electrons, protons ans neutrons results in the neutral charge of an atom?
balandron [24]
Hi :D
Neutrons are neutral so they have no charge. Electrons have a negative charge and protons have a positive charge.
For an atom's charge to be neutral there has to be an even amount of protons and electrons in the atom.

Eggs have species specific receptors on their outer surfaces to which sperm must attach if fertilization is to occur
mafiozo [28]
The  question is; would a drug that binds irreversibly to these receptors be an effective contraceptive in mammals?, the answer is;Yes; because if the receptors are blocked the sperms will not be able to penetrate the zonal pellucida of the egg.  Contraceptives prevents pregnancy by interfering with the normal process of ovulation, fertilization, and implantation.

In flies, red eyes (R) are dominant to brown eyes (r). A heterozygous fly is crossed with a homozygous recessive fly
hichkok12 [17]

Answer:

The cross of a heterozygous fly with a homozygous fly can be shown as follows:

         r            r

R      Rr           Rr

r        rr            rr

The results show that there is a 50% probability that the flies produced will have red eyes. Their genotypes will be heterozygous.

The results of the punnet square show that there will be a 50% probability that the offsprings will have brown eyes. Their genotype will be homozygous recessive.

A homozygous trait can be described as a trait which has same alleles for the gene which encodes the trait. Heterozygous means that both the alleles for the trait will be different.
