Answer:

Circulatory and Longitudinal

Explanation:

The earthworm composed of two sets of muscles which are circular and longitudinal muscles. Circular muscles are thin layers of muscles located beneath the skin and they run around the earthworm’s body. Under the circular muscles is a thicker layer of longitudinal muscles which run from anterior end to posterior end of the earthworm's body. The earthworm becomes longer and thinner on contraction of the circular muscles and when the longitudinal muscles contract the worm becomes shorter and fatter. Therefore, on alternate contracting and expanding of muscles, the earthworm moves.

1. In a pedigree, a square represents a male. If it is darkened he has hemophilia; if clear, he had normal blood
coldgirl [10]

Answer:

a, 8

b, 3

Explanation:

If the pedigree you are referring to is the one that is attached then the answer would be:

A pedigree shows how a trait is passed on throughout generations. Like it says in the question, the squares represent males. If the square isn't shaded in, then that means they are unaffected by the trait or normal. If it is shaded, they are affected.

All you need to do for the first question is count the number of squares you see in the whole pedigree. In this case, there are 8.

The second one is asking how many are affected, or have hemophilia. You need to count the number of squares that are shaded in. In the pedigree, we see 3.

Which type of unconformity occurs when sedimentary rock overlies igneous rock?
Sergio [31]

Answer:

nonconformity

Explanation:

There are multiple types of unconformity that occur in nature, all of which are base on the relative position of the types of rocks. The nonconformity is one of the unconformities. This type of unconformity occurs when sedimentary rock overlies igneous or metamorphic rocks that existed there before the sedimentary rocks covered them. The nonconformity can be seen in lots of places around the world, but it is most common on places where there are water bodies like lakes, seas, oceans, ponds, marshes, or on places where there were water bodies of this type in the past.
