Blood type is inherited based on the transfer of alleles from parents to offspring. ... Dominant alleles mask recessive alleles when a person receives both. Of the three possible blood type alleles (A, B, and O), each person receives two - one from each parent - which determines their blood type. (I just looked up ur answer and found it)
Answer:
Nitrogen cycle is a biogeochemical cycle that involves the circulation and conversion of nitrogen into different forms among the living and non-living components of the environment. The following are the steps in nitrogen fixation.
1 Nitrogen fixation.
2 Plants absorb nitrates and conduct assimilation.
3 Nitrogen flows through the food chain as a primary consumer eats the plant, and a secondary consumer eats the primary consumer.
4 A consumer releases waste and ammonification occurs to convert ammonia into nitrates and ammonium.
5 Nitrification occurs to convert ammonium into nitrates. Denitrification occurs to release nitrogen back to the atmosphere.
The correct option is this: BOTH MOVE MATERIALS DOWN A CONCENTRATION GRADIENT.
Active transport is a type of transport in the living cells in which energy is needed to move materials across a semi permeable membrane against a concentration gradient. Passive transport on the other hand is a type of transportation in cells, in which energy is not needed to move the materials across a biological membrane but the movement of the materials is against a concentration gradient.
Answer:
B) mitochondria
Explanation:
Muscle cells require energy in very high amount because most of the time they are involved in mechanical work i.e. movement and for movement we require large amount of energy. Also, we know that mitochondria are the 'powerhouse of the cell' because they are involved in ATP production which serves as energy source in our body. They are able to produce ATPs with the help of ATPase pump which are located in inner mitochondrial membrane. So, cells found in the active muscles of animals must have large amount of mitochondria so as to perform their function efficiently.
