Answer:
The eukaryotic plant animal cells are differ having some cell organelles in it.
Explanation:
The first difference is the cell wall, which is present in all eukaryotic plants. It gives shape and rigidity to the plants. But all the animal cell the outer covering is cell membrane. They lack cell wall.
All the plant cell have chlorophyll pigment. It helps them to photosynthesis. In animal cell, chlorophyll molecule are absent. So they depend on plants for their food.
The eukaryotic plant cell more space is occupied by the vacuoles. It stores food and water for the plants. However, animal cells have no vacuole or if present, it is very small in size.
All animal cells have lysosomes, which help in digestion of various materials in the cell. Plants does not contain lysosomes.
Besides this organelles all other structure of plant and animals are similar. They both have nucleus, DNA, cytoplasm, mitochondria, etc.
Answer:
Phospholipids form the basic structure of a cell membrane, called the lipid bilayer. Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent. Membrane proteins are important for transporting substances across the cell membrane
Answer: The answer is B: The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.
Explanation: An enzyme is a biological molecule which speeds up the rate of chemical reactions in the body (reactions within cells). They are proteins.
The transition state is the transition from substrate to product. The molecule is no longer a substrate but also not yet a product.
The enzyme is able to speed up the reaction by stabilizing the transition state. The transition state's energy is also the activation energy in terms of reaction. The activation energy is the minimum energy that is required to break some bonds of the reactants in order to turn them to products.

Answer:
Estrogen levels days prior to ovulation
Explanation:
Estrogen is responsible for the reproductive system in women and high levels occur naturally during menstruation as compared to glucose levels in blood as the pancreas is constantly producing more insulin to lower the glucose in blood.
Answer:
Por medio de las hojas, las plantas realizan la fotosíntesis, respiran y producen los alimentos. La respiración se produce durante el día y la noche; para ello, las plantas toman el oxígeno del aire y desprenden dióxido de carbono.
