Which of the following describes a positive feedback loop? O When blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugar concentration to a normal level.
O When the body senses that the heart rate is very high, it secretes hormones that decrease the heart rate.
O When blood sugar concentration is too high, the endocrine system secretes hormones that decrease blood sugar concentration to a normal level.
O When someone is exercising intensely, the body secretes hormones that increase oxygen supply for cellular respiration.

Answers

The statement that describes a positivefeedback loop is as follows: when blood sugar concentration is too low, the endocrine system secretes hormones that increase bloodsugar concentration to a normal level.

What is positive feedback loop?

A positive feedback loop is a feedbackloop that occurs in nature when the product of a reaction leads to an increase in that reaction.

A negative feedbackloop, on the other hand, occurs when increased output from the system inhibits future production by the system.

Therefore, the statement that describes a positive feedback loop is as follows: when blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugarconcentration to a normal level.

Glands in your neck contain digestive enzymes that help digest starch. Cells that produce and package digestive enzymes must contain relatively large amounts of __________ and ____________ in comparison to other cells.. . A). lysosomes; ribosomes. . B). ribosomes; Golgi bodies. . C). mitochondria; ribosomes. . D). Golgi bodies; mitochondria

Answers

The right answer is B). ribosomes; Golgi bodies.

Their function is the synthesis of proteins. Each ribosome consists of 2 subunits. In ribosomes there are two populations by their location, the free ribosome and those that are bound to a membrane system to form rough endoplasmic reticulum. Free ribosomes produce soluble proteins whose activity will take place in the cytosol and the nucleus. The rough endoplasmic reticulum membrane-bound ribosomes synthesize proteins that must leave the cell, such as hormones, but also synthesize proteins for membranes.

The Golgi apparatus: consists of vesicles from the rough endoplasmic reticulum, but without ribosomes (diameter 50 nm). There will be fusion of the vesicles with the dictyosomes or saccules of the Golgi of Cis side Then will advance contents, in particular the proteins on the side Cis towards the side Trans. And finally we will have budding vesicles, some surrounded by a protein structure (clathrin vesicles) on the side Trans.

If the cell must digest and package enzymes for transport, the glands will have more ribosomes and golgi bodies than other types of cells. The answer is B. Mitochondria does not produce or package digestive enzymes, and lysosomes only digest material that is engulfed into the cell.

The balanced chemical equation for cellular respiration is below. How does this equation represent the law of conservation of matter-that matter cannot be created or destroyed?C⁶H¹²0⁶ + 60² 》》》6C0² + 6H²0 + heat + ATP

A.) The inputs are different than the outputs.
B.) The atoms of hydrogen, oxygen, and carbon are rearranged.
C.) There are equal numbers of atoms on each side of the equation.
D.) The number of molecules is the same on either side of the equation.

Answers

There are equal numbers of atoms on each side of the equation. The correct answer is C.

Cellular respiration and the balanced chemical equation

The balanced chemical equation for cellular respiration, C6H12O6 + 6O2 → 6CO2 + 6H2O + heat + ATP, exemplifies the law of conservation of matter. This law asserts that matter cannot be created or destroyed, only transformed. In this equation, equal numbers of atoms are present on both sides, symbolizing this principle.

While the reactants, glucose (C6H12O6) and oxygen (O2), undergo rearrangement, their total mass remains constant. Carbon, hydrogen, and oxygen atoms are transformed into carbon dioxide (6CO2) and water (6H2O) while releasing energy in the form of heat and ATP.

This equation showcases the fundamental scientific concept of matter conservation in chemical reactions.
