What are greenhouse gases?

2 answers:

7 0

Greenhouse gases are gases that have been shown to contribute to the phenomena called the "greenhouse effect" or the idea that higher rates of certain gases in the atmosphere are causing a gradual rise in the planets temperature. Common greenhouse gases are gases that are generally released through the burning of fossil fuels. These fuels include carbon dioxide (co2), methane (CH4), Nitrous Oxide (N2o), CFCS, and Water Vapor (H2o).

Green house gas is carbon minoxid that gets into the upper atmosphere and ozone layer and it traps heat and this heat heats up the surrounding atmosphere. Green house gases have lead to Global Warming.

Find out which animal is actually most closely related to the hawk: shark, bat, or alligator. Report your findings and explanati

allsm [11]

Hi, In my opinion, bat will be the most closely related to hawk.

This is because, when we consider the photo of a bat and a hawk, we notice the similarities like:-

• Wings- They have nearly the same short wings decreasing the area of contact with air and enabling higher flight area.

• Presence of small snouted beak-like structure and presence of less or more similar color.

• Both live in trees and are normally not companiable with humans.

• Hawks and bats are both having a similar anatomy, not body, I meant that they have similar positioning of organs like stomach, pancreas etc.

• They have the sense of locating prey miles away, enabling easier locating of food.

Hope this helps...

Are scientific hypotheses proved?explain your answer

Scientific hypothesis can be proven to create a theory but not often fact. In order to be provable it has to be probable. If its not probable it's not possible.

When comparing dogs to wolves, scientists found evidence that supports the idea they come from a common ancestor. Which evidence

yanalaym [24]

Evolution overs over time such that the best traits are being passed on from successive generations in every species or populations. We can compare these different species from a common ancestor. Evidences include fossil evidence, genetic evidence, comparative anatomy and more. These are usually shown in phylogenetic trees. Most apparent differences between wolves and dogs are their anatomy or morphology. Fossils support these. Behavior between them are different especially in terms of mental differences.

Best answer is A.

In the couple described in Problem, the woman gives birth to a color-deficient but otherwise normal daughter. The husband sues f

Rashid [163]

Answer:

See the answer below

Explanation:

From the problem, color is X-linked. Males have just one (XY) chromosome while females have two (XX). Hence, for a recessive trait, males will need only one allele to be affected while females will need two alleles.

Dominant form allele for normal vision = C

Recessive form allele for color deficiency = c

Genotype of a man with normal color vision = $X^CY$

Genotype of a woman with color deficiency = $X^cX^c$

Crossing the two:

$X^CY$ x $X^cX^c$

$X^CX^c$ $X^CX^c$ $X^cY$ $X^cY$

normal female normal female affected male affected male

(a) All their sons would be affected for color deficiency. Hence, the probability of them having a color-deficient son is 100% or 1.

(b) None of their daughters is supposed to be affected for color deficiency. Hence the probability of them having a color-deficient daughter is 0.

If the woman gives birth to a color-deficient but otherwise normal daughter and husband sues for a divorce on the ground of adultery, the case will definitely stand up in the court because none of their daughters can be affected for color deficiency based on genes of the man and the woman.

In order to produce an affected daughter, the father will need to supply an affected X chromosome in conjunction with the one that will be supplied by the woman.

In this case, the man does not have an affected chromosome, hence it is not possible for them to have an affected daughter except that the woman slept with another man who happens to have an affected X chromosome.
