The cross of heterozygous
AaBb as parental phenotype led to formation of 1
6 phenotype of the offspring.This is because this is dihybrid form of inheritance .The probability of having
aabb offspring is
1/16 since there is only one aabb type of offspring phenotype out of
the
16. An illustration of how crossing is done is as per punnet square below
Answer: Well, populations never evolved than one human might have gone extinct due to many different viruses and sicknesses but other animals might not be extinct. If populations never grew more then that would be because we could not overpower dome viruses. If we never. If we never evolved animals like a Carrier pigeon would not be dead or extinct today.
Answer:
mass doubled makes KE twice as large
velocity doubled makes KE 4 times as large
Explanation:
Try it with an example
m = 4
v = 8
KE = 1/2 m * v^2
KE = 1/2*4 * 8^2
KE = 1/2 * 4 * 64
KE = 128
Now double the mass
m = 8
v = 8
KE = 1/2 8 * 8^2
KE = 1/2 8 * 64
KE = 4 * 64
KE = 256 double what it started out as.
Now do it again.
m = 4 That was the original mass
v = 16
KE = 1/2 4 * 16^2
KE = 2 * 256
KE = 512
When the velocity is doubled the KE becomes 4 times as big.
4*128 = 512
The correct answer is C. Sphagnum moss
Explanation:
In biology, a renewable source of energy refers to a type of source that replenishes and therefore can be widely used to obtain energy such as wind energy or solar energy that are almost always available. On the other hand, a seedless plant is a type of plant that does not have seed and because of this, they reproduce through sperms.
All fo the plants listed (club moss, horsetail, fern and sphagnum moss) belong to the category of seedless plants; however, from this, the only one that has been widely used a source of energy is sphagnum moss because dried sphagnum moss or peat moss is used as carbon or coals source and therefore is useful for heating building and because it is a plant that grows extensively it is also a renewable source.
