Answer
1. The vascular and dermal tissues
2. Protein capsid
Explanation
Dermal tissue present in plants offer the first defense mechanism against physical damage which could be caused by insects and infections.The dermal tissue covers the outside parts of a plant except in woody shrubs and tree which are protected by the bark. Vascular tissues in plants are responsible for the transportation of water and nutrients that are vital in cell repair and growth.Through vascular tissues, the plant obtains nutrients important for the restoration of the damaged cells.
A capsid is the protein shell of a virus.It is composed of protomers which are subunits.Some viruses are enveloped by a capsid coated with a lipid membrane called the viral envelop.The main function of a capsid is to protect the genetic material of a virus while interacting with the host environment.

Answer:
Correct
Explanation:
Homeostatic is nothing but ability of a system or living organism to manipulate its internal environment to maintain a stable equilibrium, for example the ability of warm-blooded animals to ascertain a constant body temperature.
The Homoeostatic feedback mechanism has three basis components and they are independent to one another.
These components are receptor, effector and integrating center. The function of receptor is to sense external stimuli and send information to integrating center. The integrating center generally hypothalmus in brain sends this signal to effector for example an organ to react to the stimuli.
So, the order in a homeostatic feedback system stimulus, receoptor, control centre, effector is correct.
Answer:
The animal cells get the organic compounds by eating plants. The only form of energy a cell can use is a molecule called adenosine triphosphate (ATP). Chemical energy is stored in the bonds that hold the molecule together.
Explanation:
A protein is a polymer of amino acids.
When amino acids are joined by dehydration synthesis (a process that removes
water to form a chemical bond), they form peptide bonds. <span>There are three main components of an
amino acid, the amino group, the side chain, and the carboxylic acid group. </span>
