Can someone please answer these 4 questions. I’m begging you

1. Hormones are chemical messengers that are secreted directly into the blood, which carries them to organs and tissues of the body to exert their functions.

2. Hormones are chemical substances that affect the activity of another part of the body (target site). In essence, hormones serve as messengers, controlling and coordinating activities throughout the body. (See also Endocrine Glands.)

3. hormones consist of short chains of amino acids, whereas protein hormones are longer polypeptides. Both types are synthesized like other body proteins: DNA is transcribed into mRNA, which is translated into an amino acid chain.

4. hypothalamus.

pituitary.

thyroid.

parathyroids.

adrenals.

pineal body.

the ovaries.

the testes.

true, generally referred to as invasive species given that they have no natural predators in new environment

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
