Answer:
biochemical compound
Explanation:
A biochemical compound is any compound that contains carbon and is found in
living things. They're involved in every process of life, including growth, digestion,
respiration, you name it. There are four classes of biochemical compounds :
carbohydrates, proteins, lipids (fats), and nucleic acids.
All species share a common ancestor and that change occurs over time
I think its B as A and C are definitely out
Answer:
C. carrier proteins
Explanation:
The core of the cell membrane is made up of hydrophobic tails of phospholipid. It does not allow the water-soluble material to move across the membrane. Carrier proteins are the membrane proteins that serve as transporters.
The carrier proteins bind the ion or water-soluble molecules and undergo changes in shape. This transports the molecule across the membrane. Carrier proteins serve in passive facilitated diffusion and active transport. The carrier proteins involved in facilitated diffusion transport the molecules down the concentration gradient without any expenditure of energy.
Answer:
10g
Explanation:
A cross between genotype AA BB is crossed with a plant with genotype aa bb will produce
Parent genotype:AABB x aabb
Gametes: AB x ab
F1 generation - AaBb
Since an uppercase letter contributes 4 g to weight and each allele represented by a lowercase letter contributes 1 g to weight.
Thus, 4+1 + 4 + 1 = 10g
