The answer is conduction. This is a form of heat transfer due to temperature difference, through direct contact with objects that are touching, in which the hotter object passes heat to the cooler objects by molecular collisions. Convection is another form of heat transfer in which heat travels through fluids while radiation through empty spaces.

The combination of dominant tree species in Eastern forests will likely change in the future. Some forest types,
Katen [24]

Answer:

<em>C)  Eat locally-produced and organic food; cur meat and dairy consumption.</em>

Explanation:

Eating organic food will be of no help because humans do not usually use forest trees as food resources. And hence, it will be of no help to stop the carbon dioxide emissions. Hence, option C will be of no help.

The consumption of green products will lead to lesser production of carbon dioxide and hence can be helpful. Using alternate energy sources which are not carbon based will also help to reduce the amount of carbon dioxide. If lands are restored then, these trees will not change over time. Hence, option A, B and D are helpful for  no substantial change in the tree species over time.

If a boy exhibits a sex-linked trait that is carried on the X chromosome, what must be true?
ad-work [718]

Answer;

C. His mother carried at least one allele for that trait

Explanation;

-Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father.

-A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome.

-X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele.

The overall result of the proton-proton chain is that ________
Delicious77 [7]
Basically, the P-P chain turns 4 protons into: 1 neutrino, 1 gamma ray, 1 positron, 1 helium nucleus.
A gamma ray = energy.
The chain converts hydrogen into helium and makes energy.

This is all occurring through fusion reactions where 2 protons basically smash into each other. But, it could also be e.g. a proton smashing with a deuterium nucleus. Or, other nuclei smashing together to make something else.

Hope this helps!
