A Dew forms on grass when water vapor forms when molecules cool and join together.
B Gases expand when heated and contract when cooled.
Answer: Possession of Valves
Explanation: Veins possess valves which ensures that blood flows in only one direction. Valves helps blood to flow back to the heart against gravitational force.
Arteries don't have valves because the pressure originating from the heart is capable of causing the blood to flow in one direction.
Answer:
The offspring with large, deeply colored flowers is produced from vegetative reproduction which the offspring with small, lightly colored flowers is produced from sexual reproduction.
Explanation:
Reproduction of a plant is the propagation of that plant and it occurs via the sexual or asexual means. The asexual means also called vegetative reproduction involves only one parents and the resulting offspring grows from a part of this parent. Sexual reproduction involves the union of sex cells from two parents (male and female).
In asexual or vegetative reproduction, the offsprings are genetically identical to the parent they emanate from while in sexual reproduction, the offsprings can be genetically different due to the process of recombination that occurs in gametes during their formation (meiosis). This allows for genetic variation among the offsprings.
Therefore, the offspring that resembles the parent i.e. large and deeply colored was likely produced by the vegetative or asexual means of reproduction while the offspring that exhibited a different characteristics from the parent was produced from sexual reproduction.

I don't have any notes on this but research says C! Hope this helps :)
Answer:
a.glycolysis d.acetyl CoA b.citric acid cycle e.electron transport chain
Explanation:
Cellular respiration is set of metabolic processes that occur within the cell in order to produce usable energy (ATP) from the nutrients (food). It can be divided into four main stages:
- Glycolysis-anareobic process in which glucose is broken down and it occurs in the cytoplasm. Products of glycolysis are 2 molecules of pyruvate and 2 molecules of ATP.
- Transition- Pyruvate form the glycolysis is transported into the mitochondria, where it is converted to a molecule Acetyl CoA used for further breakdown
- Citric acid cycle or Krebs cycle- aerobic process that occurs in the mitochondria matrix in which 4 molecules of ATP, and NADH are produced
- Electron transport chain-set of reactions that occur within the cristae of mitochondria. NADH and electrons are passed through electron transport chain to result in the production of ATP (32 ATPs for every glucose).
