I don't think the answer is A as that seems a bit drastic, I think it's C.
Landfills are harfull to the environment because many substances cannot decompose like styrofoam and all this matter keeps building up but never decomposes
Answer:
The correct answer is "a well-developed notochord".
Explanation:
The missing options for this question are:
A) paired fins
B) jaws
C) a well-developed notochord
D) a rasping tongue
The correct answer is option C) "a well-developed notochord".
Lampreys and hagfishes are two species of jawless fish that are uncommon to see, but they have more than 30 different species for each one of them. Both lampreys and hagfishes have a well-developed notochord, during their larvae and adult forms. The notochord provides support to their body as it has the function of a cartilaginous skeleton.
Answer:
The correct answer would be C. 0.60
It can be calculated with the help of Hardy-Weinberg equation i.e
p² + q² + 2pq = 1
Also, p + q = 1
- where p represents the frequency of dominant allele.
- q represents the frequency of recessive allele.
- p² represents the frequency of homozygous dominant genotype
.
- q² represents the frequency of homozygous recessive genotype
.
- 2pq represents the frequency of heterozygous genotype.
Number of homozygous dominant (YY) = 36
Number of homozygous recessive (yy) = 16
Number of heterozygous dominant (Yy) = 48
Total number of plants = 100
Now, frequency of homozygous dominant (YY) = 36/100 = 0.36
Therefore, p² = 0.36
So, p = √0.36 = 0.60
Hence, frequency of dominant allele (Y) = 0.60
