Compare and contrast the elevated temperature of someone who is exercising vigorously and someone who has an infection
Answers
Answer:
Due to muscle contraction and fighting of white blood cells.
Explanation:
Exercise increases the temperature of body because about 20% of the energy produced in contracting muscles is used for muscle contraction while the remaining 80% is converted into heat energy, as a result body's temperature increases whereas a person who has infection also experience high body temperature because the body work faster to fight against the infection that leads to high temperature.

Darwin mean by the term Natural Selection?
!!pleas help!! :((
Answers
Answer:
Resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
Darwin meant this my term 'Natural Selection'
Answer:
He defined natural selection as the "principle by which each slight variation, if useful, is preserved".
Explanation:
Darwin's Theory of Evolution by Natural Selection
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.

A) Pressure increases
B) Temperature increases.
C) Particles spread apart.
D)Kinetic energy increases.
E) Particle motion increases.
Answers
Answer: B, C, D, E
Explanation:
In a generalised manner B, C, D and E takes place for a substance to change state, from a solid to a gas.
What is phase transition?The physical process of changing a medium's state from one to another is known as a phase transition. The phrase is frequently used to describe transitions between the three fundamental states of matter—solid, liquid, and gas—and, in rare instances, plasma.
Heat must be used to provide energy for molecules to go through phase change. The intermolecular connections that keep the substance in its current state are broken using this energy. When the element receives enough energy, the phase change will occur.
Without going through the liquid state, sublimation is the process by which a substance moves straight from the solid to the gas state.

The Rio Grande river flows through the South Texas Plains ecoregion of Texas. The river is a major source of water for cities and farms in the area. Sometimes, so much of the Rio Grande's water is used that the river does not reach the Gulf of Mexico. How does the loss of river water affect ocean plants near the mouth of the river? A. Less sediment is deposited in the soil. B. The ocean plants cause more weathering. C. More algae grows and competes for resources. D. The slow water causes more erosion.
Answers
Answer:
A. Less sediment is deposited in the soil.
Explanation:
Less sediment is deposited in the soil if there is less amount of water receives by the ocean plants because river water brings minerals with them from passing through the mountains to the ocean. These sediments brings nutrients which are necessary for the ocean plants for their growth and development so we can say that less sediments are deposited in the soil of ocean plants due to less river water.
