In a fixed volume when temperature increases , pressure does what?

Answer:

When the volume is constant the pressure increases with temperature. 

Explanation:

Gay Lussac’s law precisely explains the relation between pressure and temperature of a system which has constant volume. In a system which has constant volume an increase in temperature indicates increase in temperature as well.

The reason behind the observation of this trend is the change in randomness of particles of the system. 

With increase in temperature the particle movement becomes random and fast. The particles hit the container walls at an increased rate and the pressure of the system increase.

Which is biotic? water temperature beeswax snow

Luden [163]

Bees wax is biotic.

Biotic means something that is related to or resulted from living things. Bio means life. Bees wax are produced by honey bees. It comes from a living thing, thus, it is biotic.

Water, temperature, and snow are all abiotic. Abiotic means "no life" or nonliving. They are not derived from any living thing.

Duchenne muscular dystrophy is an X-linked recessive disease. A phenotypically normal couple wants to start a family. The woman’

Andreyy89

Answer:

$\frac{1}{8}$

Explanation:

From the question: Duchenne muscular dystrophy is an X-linked recessive disease.

Now for an X-linked recessive disorder to be affected by a male individual; it only requires the presence of only one copy of the recessive allele of the disease to be present BUT in a female individual. both copies of the recessive allele must be present.

Let the X-linked recessive disease(i.e Duchenne muscular dystrophy) be = (ⁿ)

However, we are told that the couples are normal and are unaffected. Therefore;

the male partner (XY) will be: $X^NY$

the female partner (XY) will be: $X^NX^N$

Similarly, the question proceeds by telling us that: the woman's brother has the disease.

Definitely, it's possible that this unaffected woman is a carrier of the disease.

So, if she is a carrier; we have her traits to be: $X^NX^n$

NOW, if a cross exist between these couples; we have

$X^NY$ × $X^NX^n$

$X^N$ $Y$

$X^N$ $X^NX^N$ $X^NY$

$X^n$ $X^NX^n$ $X^nY$

So, we have offspring as follows:

$X^NX^N$ = normal unaffected female

$X^NY$ = normal unaffected male

$X^NX^n$ = female carrier for the Duchenne muscular dystrophy disease

$X^nY$ = affected male with the Duchenne muscular dystrophy disease

So, the probability of the child to be affected with the disease = $\frac{1}{4}$

Also, the probability that the first child will be a male or a female = $\frac{1}{2}$

∴

the probability that the couple’s first child will be affected = $\frac{1}{4}*\frac{1}{2}$

= $\frac{1}{8}$

Which form of reproduction would be most beneficial in an unstable environment?

Sliva [168]

Sexual reproduction would help the most because the offspring are genetically varied more than other types of reproduction and are more likely to adapt and survive.

Why do changes in suns energy affect the climate on earth

malfutka [58]

The sun is a vital part of the earth, so if it changes energy levels, it will clearly have an affect on the earth. If the energy increases, it'll most likely dry out the grass and melt the snow, etc. If it decreases, the snow could freeze and change the climate.
