does the changing seasons remove co2 from the air ? i think it might due to increased plant grwoth but im unsure.

I don't think changing seasons can REMOVE CO2 from the air, but I do think instead it could add it to the air. It's a long process that involves several ecosystems and stuff. But, as the climate is getting warmer, ice caps are melting and within these ice caps... there are trapped bubbles of CO2 that are released ( I am not sure if this adds a lot of CO2 to the atmosphere, but I am sure that it does contribute to CO2 concentration).

In relation to your last statement... plant growth would actually reduce CO2 in the air because of the process of photosynthesis. Plants take in CO2 and give out O2 for us to breathe. In turn we conduct cellular respiration in which we take in the O2 and give out the CO2. So, plants are actually one good solution for decreasing CO2 levels.

The correct answer to this question is letter A. Speciation. <span>The Galapagos finch species are an excellent example of speciation. It was Charles Darwin himself who is responsible and made the start of the study in Genetics through his natural selection and survival of the fittest. Hope this helps answer your question.</span>

In hamsters, we can examine the genes for coat color and eye color which are linked:B = brown coat, b = white coat, G = green ey

Inessa [10]

Answer:

10.2 cM

Explanation:

Given,

pure breeding parent 1 : BBgg = brown coat and pink eyes

pure breeding parent 2 : bbGG = white coat and green eyes

BBGG X bbgg = F1 = BbGg ( All are brown with green eyes )

When F1 progeny is test crossed with white coat and pink eyes hamster:

BbGg X BbGg = F2 =

brown, pink eyes = 99 = parental

white, green eyes = 103 = parental

brown, green eyes = 12 = recombinant

white, pink eyes = 11 = recombinant

Recombination frequency =

(total number of recombinants / total progeny ) * 100

= [( 11 + 12 ) / ( 99 + 103 + 12 + 11 )] * 100 = (23/225)*100 = 0.102 * 100 = 10.2 %

1 % recombination frequency = 1 cM distance between genes

Hence, the distance between B and G gene is 10.2 cM

Answer: Food groups were coded by stripes in widths corresponding to the recommended servings from each group. All the stripes tapered toward the top of the pyramid to remind people that each food group includes both healthy and unhealthy choices, such as foods with added sugar or “solid” fat.

stiks02 [169]

Answer:

If both are (PP and ww) and one is dominant the other is recessive then it is 100% purple.

IF both are heterozygous (pw) then it is 75% purple and 25% white

if one is Hetro(pw) and the other is (ww) 50% white 50% purple

VARVARA [1.3K]

Answer:

It can lead to melanoma or a time of skin cancer.

Explanation:

This is because UV radiation in sunlight can destroy the DNA by destroying the base pairing. UV light will cause two Thymine that are very closer to each other to join together to produce dimer. After which, The melanin-assisted process form lesions that is popularly called cylobutane pyrimidine dimers in DNA, which can result in mutations that cause melanoma which is a form of skin cancer
