How did these shifts in the flu
population occur?
The Vine and the
Answer:
Due to resistance.
Explanation:
Shifts in the flu population occur due to attaining resistance or having no resistance in the body against the flu. If there is resistance against a particular flu, so decrease occur in the population of people having flu and shift will decreasing over time, while on the other hand, if the population is vulnerable to the flu, more population of people get infected from that flu and shift is increasing with time.
2. Please define pH and then explain the differences
between acids and bases in terms of biology!!!!
Answer:
The pH of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with an increased number of hydroxide ions is essential and has a high pH value.
Explanation:
Answer:
pH, es la medida del grado de acidez o alcalinidad de una sustancia o una solución, un valor de pH 7 es neutro, esto significa que la sustancia o solución no es ácida ni alcalina.
Acido, es una sustancia que es capaz de liberar iones de hidrógenos en solución.
Base, es una sustancia capaz de disociar iones de hidrógenos en una solución.
Acido es una sustancia capaz de aceptar un par de electrones
Base es una sustancia capaz de donar electrones.
Acido reacciona con algunos metales, son conductores de corriente eléctrica, poseen sabor agrio, pueden destruir tejidos organicos, reaccinan con base produciendo agua y sal.
Base, no reacciona con los metales, en disolución conduce corriente eléctrica, poseen sabor amargo, cambian el color del papel tornasol del rojo al azul, en disolución son distantes al tacto, reaccionan con los acidos produciendo agua y sal

Arecent study has shown an increase in the number of predators in an ecosystem. Which of the following is a possible
cause for the growth?
A) a decrease in the land space available
B) an increase in the population of prey it feeds on
C) a decrease in the biodiversity of the ecosystem
D) an increase in the number of predators that feed on it
E) an increase in the plant life in the ecosystem
PLS HELP ASAP
Answer:
The correct answer would be - B) an increase in the population of prey it feeds on.
Explanation:
In an ecosystem, if there is an increase in the number of predators there are several possible conditions behind it. The most suitable and important factor that can lead to this is an increase of prey they rely on.
If there is an increase in numbers of prey in the particular ecosystem then there would be more food and resources for predators which help in growing the development of predators.

The flow of thermal energy is called
Answer:
The term conduction refers to the transfer of energy. Conduction occurs when energy is passed between objects. The transfer of thermal energy is called heat. Particles of matter are in constant motion. Sometimes they collide with other particles.
Explanation:
Hope this helps :D
The flow of thermal energy is called heat transfer. Heat transfer is the movement of thermal energy from a region of higher temperature to a region of lower temperature.
This transfer occurs through three main mechanisms: conduction, convection, and radiation. Conduction involves the direct transfer of heat between objects in physical contact.
Convection occurs when heat is transferred through the movement of fluids (liquids or gases). Radiation is the transfer of heat through electromagnetic waves, such as infrared radiation.
Heat transfer is a fundamental concept in thermodynamics and plays a crucial role in various natural phenomena, engineering applications, and everyday life, from cooking to climate control.

Which of the following describes the net force acting on an object?
The sum of all forces acting on an object
The gravitational force minus any contact forces acting on an object
The difference between the normal force and the gravitational force acting on an
object
The sum of all the forces acting on an object in the same direction
Answer:
The sum of all forces acting on an object
The net force acting on an object is defined as the sum of all forces acting on the object, which is the first option because the force can be external or internal, and therefore the quantity of the force on the object is more important.
What is the significance of the force on the object?Force is either internal or external, where it can change the motion, shape, or orientation of an object and in everyday life, force is involved in many activities, such as lifting, walking, and doing some heavy work, and the significance of force is closely related to the concepts of work and energy.
As a result, the net force acting on an object is defined as the sum of all forces acting on the object, which is the first option because the force can be external or internal, and therefore the quantity of the force on the object is more important.

What causes cyclones to rotate counter-clockwise in the northern hemisphere and clockwise in the southern hemisphere?
A. the Coriolis Effect
B. the jet stream
C.low-pressure air moving upwards
D. prevailing winds
Answer:
A
Explanation:
As the air rushes toward the center, it winds up moving in a curved path thanks to the Coriolis effect. This creates a circular spinning pattern as air travels from areas of high pressure to low pressure. That's why hurricanes originating in the northern hemisphere rotate counterclockwise.
Answer: the Coriolis Effect
Explanation:
The Coriolis Effect causes the cyclones to rotate counter-clockwise north of the Equator and clockwise south of the Equator.

During the process of succession, only consumers can enter a developing ecosystem before producers
Answer:
This statement is false.
Explanation:
Producers (namely mosses and liches) are the first organisms to reenter an ecosystem and are known as "pioneer species". They are proceeded by (in this order) small plants, shrubs, bushes, and climax communities (i.e. large trees). Only then do consumers once again become part of the ecosystem. For all of these reasons, the statement presented in this question is false.

How does the stomach work with other systems to keep the body healthy? (3) examples
How does the esophagus work with other systems to keep the body healthy (3) examples
Answer:
(1) Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go. (2) Filters out waste from food and pushes it through intestines and out the body (and you know how and where it gets out).
Your esophagus is an important part of your digestive system and your digestive tract. Your digestive tract is a series of hollow organs that carry food from your mouth to your anus. The food you eat can't be used for energy until your digestive system breaks it down into small molecules that your body can absorb.
