Answer:

A) Denaturation, in biology, process modifying the molecular structure of a protein.

B) Denaturation can occur when proteins and nucleic acids are subjected to elevated temperature or to extremes of pH, or to nonphysiological concentrations of salt, organic solvents, urea, or other chemical agents.

Explain the influence of the Sun and the Moon on Earth's tides. (6)

Bess [88]

Answer:

Together, the gravitational pull of the moon and the sun affect the Earth’s tides on a monthly basis. When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides — both commonly called spring tides.

Explanation:

Tidal Variations - The Influence of Position and Distance Together, the gravitational effects of the moon and the sun affect the Earth’s tides on a monthly basis. The elliptial orbits of the moon around the Earth and the Earth around the sun have substantial effects on the earth’s tides.

The two systems that work together to cause this reaction are the endocrine system that secretes the hormone and the

Simora [160]

Two control systems of the body

Endocrine and Nervous

Endocrine and nervous system similarities

-Work together to maintain homeostasis

-Release ligands (chemical messengers) that bind to cellular receptors on particular target cells

Endocrine and nervous system differences

Endocrine system: -Transmits hormones through blood

-Targets any cell in the body with the correct receptor

-Very widespread

-Exhibits longer reaction times and has longer-lasting effects

Endocrine System

-Composed of ducts and glands that synthesize and secrete hormones

-Hormones are released into the blood and transported throughout the body

Endocrine system regulation growth and development

-Changes measured from birth to puberty

-Hormones help regulate embryonic cell division and differentiation

-Hormones regulate metabolism

How does the endocrine system maintain homeostasis or blood composition and volume

-Hypothalamus

-Hormones regulate blood solute concentrations (ex glucose ions)

-Hormones regulate blood volume, cellular concentration, and platelet numbers

The endocrine system controlling digestive processes

-Trigger digestion when food is in the stomach

-Hormones influence secretory processes and movement of materials in the digestive tract

Endocrine System controlling Reproductive Activities

-Make sure sperm and egg make it to each other

-Hormones affect the development and function of the reproductive system and the expression of sexual behavior

Endocrine Glands

Contain epithelial tissue that makes and releases hormones within a connective tissue framework

Endocrine Organs

-Glands with solely endocrine functions

-Ex: Pituitary, pineal, thyroid, parathyroid, and adrenal

Endocrine Cells

-Found in clusters in organs with another function

-Examples in Hypothalamus, Thymus, Heart, Stomach, Liver, Pancreas, Small Intestine, Adipose Connective Tissue

-Pancreases is not an endocrine gland, but it does release hormones

Cual es la relación del ADN con el tamaño de la bacteria?

rodikova [14]

Por lo tanto, la proporción de ADN no codificante aumenta con el tamaño del genoma más rápidamente en las no bacterias que en las bacterias. Esto es consistente con el hecho de que la mayor parte del ADN nuclear eucariota no codifica genes, mientras que la mayoría de genes procariotas, virales y orgánulos sí lo son.

What does a plant need to create a glucose molecule in photosynthesis?

DerKrebs [107]

Answer: 1 glucose

Explanation: Basically, in photosynthesis, energy from light is used to convert carbon dioxide and water into glucose and oxygen. For 6 carbon dioxide and 6 water molecules, 1 glucose molecule and 6 oxygen molecules are produced. So your answer is 1 glucose. BTW, I got my answer from Google and from the website called thoughtco Go check it out!
