Answer:
Hypothalamus
Explanation:
The hypothalamus is a part of the brain which possesses temperature receptor cells that detect changes in the man’s temperature, thereby sending signals in the form of electrical nerve impulses to the man’s muscles and nervous system, which in turn respond in counteracting the drop in the normal temperature of the body.
Once the muscle cells of this man receive these signals, they produce heat through thermogenesis by shivering when the muscle cells begin to contract. This is one of the mechanisms by which thermoregulation is achieved as controlled by the hypothalamus in the brain of the man.

Beyond size, the main structural differences between plant and animal cells<span> lie in a few additional structures found in </span>plant cells. These structures include: chloroplasts, the cell<span> wall, and vacuoles. For now you can use this to figure it out until you send me a picture of the model.

Predators and prey are both in a constant struggle for survival, foxes with bigger ears tend to catch more mice, and live longer, because of this, foxes with smaller ears don't live as long, pretty soon all foxes have larger ears. The same goes for prey, Mice with padded feet live longer due to the foxes having more trouble hearing them, pretty soon all mice have padded feet, and the cycle continues.
Answer:
The order of bonds in increasing order of bond strength would be Ionic, peptide, polar covalent, non-polar covalent hydrogen bond.
Ionic bonds are the strongest bonds which are formed by transferring of valence electrons between different atoms. For example, a bond between sodium and chlorine atoms in NaCl.
A peptide bond is a type of covalent bond formed between a carboxylic group of one amino acid and the amino group of another amino acid. It is provided with extra stability through resonance.
A covalent bond is a type of bond which is formed by the sharing of electrons between two atoms.
They bond strength of these bonds is less than that of ionic bonds and more than that of hydrogen bonds.
Hydrogen bonds are weak bonds formed through electrostatic interactions between a proton present in one molecule and an electronegative atom in another molecule.
