<span>Answer:
TT=90
Tt=420
tt= 490
When there is 2 type of allele, there will be 3 possible genotypes: homozygous dominant, heterozygous, homozygous recessive. Dominant phenotype will be expressed for </span>homozygous dominant and heterozygous. That mean, the number of homozygous would be:
TT+Tt= 510
total population= TT + Tt + tt
1000= 510 + tt
tt=490
The frequency of recessive allele would be:
t= √(490/1000)= √0.49= 0.7
After that, you can find the frequency of the dominant allele
T+t= 1
T+0.7=1
T=0.3
Using both frequency, you can find the number of homozygous dominant (TT) and heterozygous (Tt) population
TT= 0.3 *0.3 * 1000 individuals = 90 individuals
Tt= 2 * 0.3 * 0.7 * 1000 <span>individuals</span>= 420 individuals
<span>The only incorrect
answer is d. within very short spans of time.<span>
<span>In his
Theory of Evolution, Darwin
noted three patterns of biodiversity:</span>
<span>1.
Species vary globally - different, but ecologically similar animal species inhabit separate habitats around the
Globe, but again, these habitats are ecologically similar.</span>
2.
Species vary locally - different animal species that are related to each other,
may occupy different habitats in an area not so far away.
<span>3.
Species vary over time - some traits become more common, other less common.

Answer:
They can't be in the same phylum because they are in two different categories on the basis of Mode of nutrition. Plants are autotrophs, while animals are heterotrophs. Cell wall is present in plant cells, while it is absent in animal cells.
Explanation:
A phylum is a major group of animals or in some classifications plants sharing one or more fundamental characteristics that set them apart from all other animals and plants/
Answer:
Global warming occurs when carbon dioxide (CO2) and other air pollutants collect in the atmosphere and absorb sunlight and solar radiation.
