What might happen to the Earth if human increase the amount of greenhouse gasses?
KonstantinChe [14]

Answer:

Global warming will occur

Explanation:

Greenhouse gases are special gaseous compounds that have this ability to trap HEAT due to their structural composition. They include; carbon dioxide (CO2), chlorofluorocarbons (CFC), methane (CH4) etc.

Anthropogenic activities such as burning of fossil fuels etc. release these gases into the atmosphere where they cause harm to the Earth. Greenhouse gases contribute immensely to the GLOBAL WARMING EFFECT, which is the increase in the temperature of the Earth surface. Therefore, if humans increase the amount of greenhouse gases in the atmosphere via their actions, there will be a GLOBAL WARMING occurrence.

Color in poison dart frogs is controlled by a single gene with multiple alleles. A blue poison dart frog that is heterozygous fo
8_murik_8 [283]

Answer:

Cb>Cy>Co>Cr

Explanation:

First of al we need to do the Punnett square. As a result we get the genotypes:

CyCb

CyCr

CoCb

CoCr

Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype.

Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.

The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.

As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.
