Which statements describe the effects of the solar wind on Earth? Check all that apply. The solar wind produces the northern and

Andrei [34K]

The correct answers are:

• The solar wind produces the northern and southern lights

• The solar wind disrupts communication systems.

• The solar wind distorts Earth's magnetic field.

Solar winds are geomagnetic stream of charged particles radiated from the outer atmosphere of the sun. All planets are protected from solar winds via magnetic fields but planets that are positioned closer to the sun can experience degeneration of the magnetic field.

Solar winds are capable to distort and even destroy the functioning of communication satellites in outer space, such as radio and tv communication and satellite based internet services.

The effects of solar winds that are visible to naked eye are the Aurora Borealis (the Northern lights) and the Aurora Australis (the Southern Lights).

Archaea

Explanation:

All observations and information that scientists perceive and record are called data.
A dependent variable, also known as response variable, defines the treatment/variable that changes in response to the independent variable.
According to the second postulate of the Cell Theory, the cell is the basic structural and functional unit of life.
Cells that perform similar functions are grouped together to form tissues.
An experiment is a controlled setting/test that investigates (proves or disproves) a scientist's hypotheses.
One of the major properties of life is to harvest and convert energy to drive basic cellular processes.
Independent or test variable does not depend on any other factors. It is itself changed to determine its effect on the response variable.The amount of coke is the independent variable.
Homeostasis is defined as an organism's ability to regulate its internal environment in response to fluctuations in the external environment.
A community is a group of populations (different species) inhabiting one place at one time.
In the scientific method, a good theory generates further hypotheses that can be tested.
Multicellular organisms are composed of more than one cells.
Biology is the scientific study of life. <em>Bio</em> means life and <em>logos</em> means study, thought or reasoning.
An ecosystem is an ecological structure in which both biotic and abiotic factors interact with each other.
According to the second postulate of the Cell Theory, the cell is the basic structural and functional unit of life.
Eukaryotes constitute one entire domain of the tree of life. They are distributed in 4 major kingdoms of life.
A dependent variable, also known as response variable, defines the treatment/variable that changes in response to the independent variable.
Homeostasis is defined as an organism's ability to respond and regulate its internal environment in response to fluctuations in the external environment.
Homeostasis is defined as an organism's ability to respond and regulate its internal environment in response to fluctuations in the external environment.
The experimental and control groups differ in the independent variable as only the experimental group receives the variable or treatment.
Quantitative data is quantifiable, numerical data in which the effects of the independent variable on the response variable can be compared through mathematical and statistical tools.
A good theory is universal,broad in scope and substantiated by a large body of evidence.
A good theory is universal,broad in scope and substantiated by a large body of evidence.
A jungle is a group of a single species of dense vegetation.
An organism is an individual living being composed of cells, tissues, organs and organ systems.
Fungi, being saprophytic in nature are the principal decomposers on Earth.
Independent or test variable does not depend on any other factors. It is itself changed to determine its effect on the response variable.
A population is a single species of organisms inhabiting a single area at a time.
Organisms of the domain Archaea are known to be extremophiles i.e. organisms that can survive and thrive in harsh environmental conditions.
A hypothesis is a potential explanation for observable phenomena.
The three domains of life: Eukarya (Eukaryotes), Archaea and Bacteria (Prokaryotes).
The three domains of life: Eukarya (Eukaryotes), Archaea and Bacteria (Prokaryotes).
A cell is made up of different organelles performing diverse functions for the cell.
The properties of life include: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing.
Each level of the hierarchy of life entails the addition of new properties, complexity and more complex functions.
One of the major properties of life is to harvest and convert energy to drive basic cellular processes.
A well tested and substantiated hypothesis leads to the development of a theory that can further be subjected to experimentation.
An ecosystem is an ecological structure in which both biotic and abiotic factors interact with each other.
Independent or test variable does not depend on any other factors. It is itself changed to determine its effect on the response variable.
The three domains of life: Eukarya (Eukaryotes), Archaea and Bacteria (Prokaryotes).

Paul had chicken pox when he was 5 years old. nicholas received the chicken pox vaccines. which type of immunity does each man h

GrogVix [38]

Answer:

Paul has natural active immunity, while Nicholas has artificial active immunity.

Explanation:

Natural active immunity is an immunity that occurs when an individual is exposed to a disease causing organism, gets infected, and also become immune to the disease due to the primary immune response. From the question, Paul has natural active immunity because he had chicken pox before, and the virus that causes chicken pox has interacted with his immune response, hence, making him to develop natural immunity to the disease.

Artificial active immunity is an immunity that an individual acquires when small amount of immunity to a disease is deliberately exposed to his body. Artificial active immunity is usually produced in the form of vaccinations. From the question, Nicholas has artificial active immunity because chicken pox vaccines were intentionally introduced to his body.
