Answer:
The pulmonary veins carry oxygenated blood to the heart. Air enters the bronchioles in the lungs and reaches the alveoli. The capillaries join together to reach the arteries, transferring the oxygen. The oxygen-rich blood moves from the aorta and reaches the kidneys through a series of blood vessels.
Answer:Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: ... Hardness: All metals are hard except sodium and potassium, which are soft and can be cut with a knife. Valency: Metals typically have 1 to 3 electrons in the outermost shell of their atoms.
Explanation:
Answer:
They could have all four type phenotype that are A, B, AB, and O
Explanation:
If the man has A blood group and the woman has B blood group then the genotype of man can be IAIA or IAi and the genotype of woman can be IBIB or IBi.
IA i
IB IAIB IBi
i IAi ii
So if the genotype of the parents are IAi and IBi then out of four offspring one could have AB blood group, second could have B blood group, third could have A blood group and fourth could have O blood group as shown in the cross above.
Answer:
Eukaryotes
Explanation:
Eukaryotic cells have membrane bound organelles.
Prokaryotic cells do NOT have membrane bound organelles.
So, a Eukaryotic cell has structures such as a nucleus, mitochondria, a golgi complex, etc. This provides the cells with distinct stuctures that have distinct functions.
consider the expression of a protein (protein synthesis.) Transcription of the DNA into RNA happens within the nucleus. The mRNA is sent from the nucleus to the cyctoplasm, where translation occurs at either the rough endoplasmic reticulum or the free floating ribosomes.
A prokaryotic cell has all of its machinery floating around inside its cytoplasm with no separation. In these cells, transcription and translation both occur in the cytoplasm. In fact, translation often begins before transcription is finished...
Answer:
The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. ... At the first trophic level, primary producers use solar energy to produce organic material through photosynthesis. The herbivores at the second trophic level, use the plants as food which gives them energy.
