Answer:
a. 10 species per day
Explanation:
The current rates of extinction are incredibly high, much higher than what is the natural average of extinction of the species. Even though it stands that around 10 species are getting extinct every day, there's many clues that suggest that the number reaches incredible 150-200 species per day. This just backs up the statements of numerous scientists that we are actually creating the sixth mass extinction that Earth has experienced, as such rates of loss of species are typical only for mass extinctions.
First, to answer this question, you need to draw a Punnett square. So you put the homozygous short alleles (tt) on top of the square, and the heterozygous tall alleles (Tt) on the left side of the square (or vice versa, it doesn't really matter).
When you create the Punnett Square, you then perform the cross between the two plants' alleles. I cross t with T and that gives me Tt. Same with the next one, t and T becomes Tt. Then, I cross t with t and that gives me tt. Same with the next one, t and t becomes tt.
So, the answer here would then be c. 50 percent Tt, 50 percent tt. You might say, well, couldn't answer d also work? Answer d could only work if the question was asking for the phenotypic ratio of the offspring. Then you could say 50% tall, 50% short. But the question asks for the genotypic ratio, so it would instead be c. 50 percent Tt, 50 percent tt.
Hope this helps!
They were gigantic. Way bigger than a normal toroise
Answer:
D.
Explanation:
Animals need oxygen (O) to survive. It's purpose is to bring oxygen into your body. One of the products of cellular respiration is carbon dioxide. Your respiratory system also helps your body get rid of that carbon dioxide.
