Both have increased gradually over the past 150 years.
- Global warming is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect.
- Global warming is the increase of the Earth's average surface temperature due to accumualtion of greenhouse gases in the atmosphere. Climate change is a broader term that refers to long-term changes in climate, including average temperature and precipitation.
- Effects of global warming are rising sea level Increased temperature, Habitat damage and species affected Changes in water supply
- Burning of fossil fuels, pollution from coal, natural gas, and oil are reason of global warming happening

Pink snapdragons are a result of incomplete dominance. Cross-pollination between red snapdragons and white snapdragons result in pink when neither the white or the red alleles are dominant. The fruit color of eggplants is another example of incomplete dominance.
Answer:
Inbreeding and greater chance of passing deletereous mutations through generations
Explanation:
There are several reasons why small populations are more prone to genetic diseases. One of them is that in small populations there tends to be more inbreeding
, that is breeding between individuals are closely related. Inbreeding increase the chances of offspring being affected by deletereus homozygous genotypes.
On the other hand, the acquisition of a deleterious mutation in a small population is more likely to be spread in that small population than in a large population.
Answer:
A. 100%.
Explanation:
Since both spiders have either AA or aa, every possible combination would result in an Aa genotype. And, because A is dominant to a, they will all display the A trait—be patterned instead of plain.
So it is 100%.
The effects of the intertidal zone on two species of snails, and how an adaptation can help in an organism's survival.
Periwinkle (Littorina specie) is a very common snail that is found in the upper intertidal zone due to their adaptation abilities which increase its survival in its environment. They are small in size i.e. less than 1/4 inch and feed on micro algae that grows on the exposed rocks.
Snails close them in shells and excrete a sticky mucous that firmly attaching the animal to the rock of seagrass. so we can conclude that adaptation can help in an organism's survival.
