Which Option Describes A Step In Designing Experimental Procedures?

Answers

Answer 1

Writing a hypothesis that must be true can describe a step in designing experimental procedures.

What does a research hypothesis entail?

A hypothesis outlines your expectations for the results of your investigation. It is a speculative, untested response to your research question. You might need to develop a number of hypotheses for some research projects that speak to various facets of your research issue.

Simple hypothesis, complicated theory, direction-based theory are types of a hypothesis.

What role does a hypothesis play in research?

As previously said, a hypothesis serves as a response to the research question and directs the gathering and analysis of data. Researchers can use hypotheses to both identify relationships between variables and forecast relationships based on theoretical principles and/or empirical data.

materials move down a concentration radeient
the methods cells use to materials with out expanding energy

Answers

Materials move down a concentration gradient  is called a concentration gradient and the methods cells use to materials with out expanding energy is called Passive transport.

How can you move substances down the concentration gradient without using energy?

Passive transport tells  more about the shifting of substances down a concentration gradient and does not need any issue of energy consumption.

A concentration gradient is simply a stretch of space across which a substance's concentration alters. Substances will naturally travel down concentration gradients, from a higher concentration point  to a place or area that is known to be lower concentration area.

Therefore, substance diffuses over a membrane through passive transport as it diffuses along its concentration gradient without requiring any energy from the cell.

Explanation:

glycolysis is the first way involved in cellular respiration.

The correct option is B. Fatty acids that are broken down for energy production are utilized for which aspect of cellular respiration is glycolysis.

What is glycolysis?

Through a sequence of processes known as glycolysis, glucose is divided into two pyruvate molecules, each of which has three carbons. Since the majority of species alive today still use glycolysis, it is an old metabolic route that developed long ago.

Glycolysis is the initial step in the process of cellular respiration in organisms. However, many anaerobic organisms—organisms that do not use oxygen—also contain this route since glycolysis does not require oxygen.

You push a book and it leaves your hand then slides along the table. the book covers a total distance of 1m the distance that you use to determine the work that you did is?

Answers

The distance used to determine the work is less.

What is work done?

When an external force drives an object a specific distance, it transfers a certain amount of energy to the object, which is known as work. The amount of work performed on an object is a measure of the energy transmitted to it. Work is defined as the sum of the force component acting in the displacement direction and the displacement magnitude (d).

A measurement of the energy that is transferred when an object is moved over a distance by an external force, at least some of which is applied in the direction of the displacement.

The output of a force is calculated by multiplying its component acting in the displacement's direction by its magnitude.

What causes cells to stop growing?

According to research coauthor and geneticist at Harvard Medical School Stephen Elledge, cell death — the stopping of cells from growing and dividing — is caused by extreme stress and genetic damage.Specifically because to water pressure, plant cells maintain their form.Water is actively pumped into plant cells to maintain their rigidity.The cellulose and pectin-based cell wall's durability prevents the cells from bursting under pressure.All living cells need a little chemical known as adenosine triphosphate (ATP) as fuel, which is one of the earliest and most persistent lessons that students learn in biology class. Numerous genes play a role in regulating cell division and development.The cell cycle is the orderly, sequential process by which a cell duplicates itself.This process is tightly regulated to guarantee that the DNA of a dividing cell is accurately duplicated, that any DNA errors are corrected, and that each daughter cell obtains a complete set of chromosomes.Checkpoints, also known as restriction points, are locations in the cell cycle when specific genes can check for issues and stop the cycle for repairs if something is wrong. A cell may self-destruct if there is a DNA mistake that cannot be corrected (apoptosis).Apoptosis is a process that occurs frequently throughout life to help the body get rid of cells that are no longer functional or that are unnecessary.A type of white blood cell known as a macrophage dissects and recycles cells that have undergone apoptosis.Apoptosis plays a critical function in the development of the embryo and the maintenance of adult tissues, as well as protecting the body by eliminating genetically compromised cells that could cause cancer. Diseases like cancer can result from an alteration in the cell cycle's regular regulation.Cells can divide randomly and collect genetic mistakes that can result in a malignant tumor when the cell cycle is out of control.

Earth's magnetic field, or magnetosphere, extends from the planet's core out into space, where it meets the solar wind, a brook of charged particles emitted by the sun.  The ozone layer buckles us from the harmful effects of immoderate UV radiation, which can lead to sunburn, skin cancer, and eye damage. Earth's magnetic field serves to divert most of the solar wind, whose charged particles would else strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, ozone layer stream of charged particles emanating from the Sun.
