The diagram below shows a portion of the concept map for the Rock Cycle:
(shown below)
Which of these would best fit in the missing part of the cycle?
Magma
Lava
Sedimentary rocks
Sediments
Answer:
Sedimentary Rock
Explanation:
The option that would best fit in the missing part of the rock cycle is the sedimentary rocks. Thus, the correct option for this question is C.
What is the Rock cycle?The rock cycle may be defined as a series of processes that a rock of the earth's crust can undergo in its lifespan. These processes significantly illustrate the transformation of a rock's state from one form to another.
The conversion of metamorphic to sedimentary rock is mediated by the process of weathering. Metamorphic rocks will be exposed to weathering processes and may break down into sediment. These sediments could then be compressed to form sedimentary rocks, which would start the entire cycle anew.
Therefore, the option that would best fit the missing part of the rock cycle is the sedimentary rocks. Thus, the correct option for this question is C.

What percentage of the offspring will have the type a blood phenotype
If father is heterozygous there are 50% chances of having blood type A, and if father is homozygous, every child will carry blood group A.
What is blood group?Based on presence and absence of antigens and antibodies on surface of red blood cells, blood is classified as blood groups. These antigens can be proteins, carbohydrates, glycolipids, or glycoproteins.
There are two types of blood grouping. ABO and Rh, where ABO denotes persons blood group as A, B, AB, O and Rh denote Rhesus positive and Rhesus negative blood type.
Blood groups are inherited from both parents. If type A is inherited from one parent and type A or O inherited from another parent blood group of offspring will be A.
Therefore, there are 50% of chances that offspring will have A blood type.

Complete the following sentence: Oxygen is taken into cells by the process of.....
Oxygen is taken into cells by the process of simple DIFFUSION.
Simple diffusion is a cellular process by which small molecules (e.g., oxygen and carbon dioxide) pass across the plasma membrane and thus can enter and leave the cell.Simple diffusion always occurs in favor of a concentration gradient, i.e., from a region of high concentration to a region of low concentration.For example, oxygen (O2) molecules move from a region of high concentration in the lungs to a region of low concentration in the blood.This process (diffusion) does not require energy to move molecules across biological membranes.In conclusion, oxygen is taken into cells by the process of simple DIFFUSION.
