Answer: :Total distance to be travelled = 4.4 km
= 4400 m
Diameter of wheel = 70 cm = 0.7 m
Radius of wheel= 0.7 / 2 m
Circumference of wheel = 2 * pi *r
= 2* 22*0.7 / 7* 2
= 22*0.1
= 2.2 m
No. Of revolutions = Total distance / Circumference of wheel
= 4400 / 2.2
= 2000
Explanation:
Answer:
There are two alleles, the recessive yellow allele and the dominant brown allele. The female is hom0zygous recessive while the male is heterozygous, this means that half of their children will be hom0zygous recessive and be yellow. The other half will be brown and heterozygous, meaning they have a yellow allele and a brown allele. If the female mated with a hom0zygous dominant male, then all of their offspring will end up being heterozygous and brown.
Answer:
Their similarity
Explanation:
Pharyngeal pouches are structures in vertebrates that develop in different parts of the body mainly in the face or neck. The similarity in their position and structural indicates a similarity . These structures provide evidence of evolution that the organisms evolved from the same ancestry.
The first option is correct.
Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.
The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.
Hope it helped,
Happy homework/ study/ exam!
