Answer:
Depends on the genotype of the parents the child could be any blood type A,B,AB,O. Blood type A & B are dominant over O , so the parents could be heterozygous (genotype AO & BO, they have each the allele for the recessive blood O) and homozygous (genotype AA & BB).
# If the both parents have homozygous (genotype AA & BB) than the offspring will be blood type AB.
# If the parents have heterozygous (AO & BO) then the offspring will be A,B,AB,O.
# If the genotype of parents are AO & BB then the offspring will be AB, B.
# If the genotype of parents are AA &
BO then the offspring will be AB , A.
Crab in Rocky shore By rock pools - deep in ocean as they get older
Typical day - just shuffle along the rocks
To get food - from rock pools use claws to get fish
As they get bigger, they eat protozoa, diatoms and smaller crabs that live on the ocean floor. When the crabs reach 2 to 4 years of age, they move to deeper water where they join the adult crabs that eat worms, clams, mussels, snails and sea urchins. They also eat sand dollars, barnacles, fish parts and algae.
Hard shell is their protection and claws as a defends mechanism
PredAtors - possibly birds while on shore but bigger fish on ocean floor
Answer:
Explanation:All matter has mass and occupies space. All physical objects are made of matter. Matter itself is composed of tiny building blocks known as "atoms".
Genes are composed of stretches of DNA, a complex molecule shaped like a twisted ladder or staircase.
The shape of DNA is a double helix, which is like a twisted ladder. The sides of the ladder are made of alternating sugar and phosphate molecules. The sugar is deoxyribose. The rungs of the ladder are pairs of 4 types of nitrogen bases. A is always paired with T and G is always paired with C.
