The right answer is B. The tree absorbing carbon dioxide
The Earth's atmosphere is the gas / particles surrounding our planet. Most of the air consists of nitrogen, oxygen, then other gases, including argon and carbon dioxide.
Biosphere is a planetary system including all living organisms and environments in which they live (the tree in this exercise).
2 daughter cells, 12 chromosomes each
mitosis maintains diploid number, only meiosis becomes haploid (half number of chromosomes)
Answer: Option A ,Band C
Explanation:
Red blood cells are called erythrocytes. They are produced from the bone marrow and deposited into the blood stream when they are matured. The red blood cells carry oxygen through out the body.
Lymphocytes are white blood cells that are produced from the bone marrow and help in body defence, they are found in lymph tissues. They are immune cells.
Platelets are tiny cells that contribute to blood clots
Answer: The answer would be Precipitation.
Explanation:
The correct answer is:
electronegativity
Explanation:
Electronegativity is a model of an atom's strength to attract the shared electrons of a covalent bond to itself. If atoms bonded together have the same electronegativity, the allotted electrons will be moderately shared. If the electrons of a bond are higher attracted to one of the atoms (because it is more electronegative), the electrons will be unevenly shared. If the difference in electronegativity is large enough, the electrons will not be allowed at all; the more electronegative atom will "take" them happening in two ions and an ionic bond.
