Lysosomes break down food and worn out cell parts
Answer:
1. Supplying
2. Taking
Explanation:
Food chain is a linear relationship between organisms that depicts the flow of energy from one organism to another. In a food chain, organisms are arranged in trophic levels where arrows pointing to the right direction (➡) are used to show that the organim the arrow is pointing to eats the organism behind it.
Hence, according to this question, arrows in a food chain point from the organism SUPPLYING the energy to the organism TAKING the energy.

Multi cellular organisms are made up of billions of cells each specialized to a unique role and these cells are organized into structural and functional units such as tissues and organs.
For each cell and organ to function optimally, it requires oxygen and nutrients and needs carbon dioxide and metabolic waste taken away in a continuous, never ending process.
<span>A mechanism is needed to accomplish the important function of transporting the relevant materials to and from the cell. The circulatory system fits this bill splendidly. It is a specialized organ system which allows blood and lymph to flow through the entire body carrying nutrients such as glucose, amino acids and electrolytes as well as oxygen to each cell, at the same time carting away carbon dioxide and all sorts of metabolic waste over to excretory organs to be expelled from the body.

Answer:
Transitional fossils show how a particular taxa accumulated adaptations to fit particular environments and/or ecological niches
Explanation:
Transitional fossils are fossilized remains of taxonomic groups/species that illustrate an evolutionary transition between a known version of a taxa/species and the current taxa/species. Transitional fossils are fundamental because they can be clearly differentiated from the ancestral group as well as of its derived descendant group. For example, there exist transitional fossils known as "mammal-like reptiles"(i.e., therapsids that gave rise to the true mammals), which are clearly different from current mammals.
Answer: A. Research into a phytochemical from a plant which might inhibit cancer development.
Explanation:
The chemoprevention is a process of utilization of chemical formulations such as medication, supplements and vitamins to the stop the growth of cancer cells. This is necessary and important for people which are at high risk of developing cancer.
The research for the phytochemical derived from the plants can be an example of chemoprevention as this will help in inhibiting the cancer development.
