During exercise, sensory receptors detect changes in oxygen and carbon dioxide levels in the blood. This information is then sen

t to the brain's medulla, which causes the heart to beat faster and increases the rate of breathing. Exercising also causes the nervous system to signal the pancreas and thyroid gland to release hormones which regulate metabolism. Which statement is best demonstrated by this scenario? A. Hormones act as signal molecules between all body systems. B. Exercise is important for the body to function properly. C. Nerves transmit and respond to every major system in the body. D. Increased heart rate and blood flow decrease oxygen supply.

A. Hormones act as signal molecules between all body systems

Peripheral Chemoreceptors (Carotid + Aortic Bodies) and Central Chemoreceptors in the Medulla Oblongata detect high Carbon Dioxide levels in the blood during exercise. The respiratory centre in the Medulla Oblongata + PONS stimulate the intercostal muscles and the diphragm to contract in order to increase the rate and depth of breathing as to decrease levels of Carbon dioxide in the blood.

The thyroid gland secretes thyroxine which speeds up metabolism (the rate at which cells use glucose)

A proficient engineer can easily design skeletal structures that are more functional than those currently found in the forelimbs
Darina [25.2K]

Answer:

Natural selection is generally limited to modifying structures that were present in previous generations and in previous species

Explanation:

The basic idea of biological evolution is that populations and species of organisms change over time. Today, when we think of evolution, we are likely to link this idea with one specific person: the British naturalist Charles Darwin.

In the 1850s, Darwin wrote an influential and controversial book called On the Origin of Species. In it, he proposed that species evolve (or, as he put it, undergo "descent with modification"), and that all living things can trace their descent to a common ancestor.

Natural selection, genetic drift, and gene flow are the mechanisms that cause changes in allele frequencies over time. When one or more of these forces are acting in a population, the population violates the Hardy-Weinberg assumptions, and evolution occurs. The Hardy-Weinberg Theorem thus provides a null model for the study of evolution, and the focus of population genetics is to understand the consequences of violating these assumptions.

New gene variants (i.e., alleles) are produced by random mutation, and over the course of many generations, natural selection may favor advantageous variants, causing them to become more common in the population.

When two objects are near each other, how would increasing one object's mass affect it
Bumek [7]

Answer:

When two objects are near each other, increasing one object's mass would cause the gravitational force of the object to increase. where m and M are the masses of the two objects, d is the distance between their centres, and G is the gravitational constant.

Explanation:

one is big one is small
