Suppose a scientist developed a hypothesis stating that a certain substance slowed down the growth of chili pepper plants. Briefly describe a controlled experiment
the scientist could conduct to test the hypothesis. Identify the controlled variables, the independent variable(s), and the dependent variable(s).

Answers

Answer 1

Answer:

The experiment consists of three different treatments:

1- Fifty (50) chili pepper plants treated with the substance X suspected to slow down the growth  

2- Fifty (50) no treated chili pepper plants that grown in normal conditions

3- Fifty (50) chili pepper plants treated with a substance known to slow down the growth (positive control)

Dependent variable: plant growth

Independent variable: the amount of substance x (suspected to slow down plant growth)  

Explanation:

The dependent variable is the variable that is being measured, while the independent variable isn't changed by the other variables in the experiment. In this case, the question is how chili pepper plants grow in response to the substance x, which is suspected to slow down the plant growth. During the experimentation, the plant growth will represent the dependent variable being analyzed. On the other hand, chili pepper growth will be in response to changes in the amount of substance x the plants receive, therefore being the independent variable.

Answer 2

Hypothesis development  for substance.

A hypothesis is a temporary or tentative arrangement or explanation that is made for the experiment on the basis of an assumption. The experiments highlight the development of certain substances that slowed down to the growth of the chili pepper plans.

Thus the answer is slow growth, normal growth, and positive fast growth.

The assumed experiment consists of 3 treatments. As the first (50) chili pepper plants treated with substance X tend to slow down the growth. The second plant shows a grown in normal conditions. The 3rd plant sows the slow down the growth (positive control).Thus the dependent variable is then planted growth and the independent variable is substance X.

Answers

Answer:

By 1920, physicists knew that most of the mass of the atom was located in a nucleus at its center, and that this central core contained protons. In May 1932 James Chadwick announced that the core also contained a new uncharged particle, which he called the neutron. Chadwick was born in1891 in Manchester, England.

Answer:

In May 1932 James Chadwick announced that the core also contained a new uncharged particle, which he called the neutron. Chadwick was born in1891 in Manchester, England.

Explanation:

Neutrons come from fusion. Let's say you push two protons together enough for them to "touch", specifically for them to experience attraction from the strong nuclear force that is stronger than electrostatic repulsion.You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there.

why virus is imortal?​

Answers

Answer:

Strictly speaking, viruses can't die, for the simple reason that they aren't alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can't thrive independently. Instead, they must invade a host organism and hijack its genetic instructions.

Explanation:

Answer:

A flu is a virus and the reason that you have to get flu shots every year is because every time a virus enters a host it is mutated by the antibodies, cells and biology of that host, so it can be passed on to another host who may not be immune to every part of this NEW virus.

Lenny accidentally drops his matchbox car into a graduated cylinder. The car has a mass of 10 grams and the water level in the cylinder rises from 41 ml to 46 ml. Determine the density of the matchbox car. The formula for density is D =
m
v
.
A) 0.5 g/ml
B) 2 g/ml
C) 15 g/ml
D) 50 g/ml

Answers

Answer:

B) = 2 g/mL

Explanation:

Given data:

Mass of car = 10 g

Volume of water = 41 mL

Volume of water+ car = 46 mL

Density of car = ?

Solution:

Density is equal to the mass of object divided by volume of object.

Formula:

d = m/v

volume of car =  Volume of water+ car - Volume of water

volume of car = 46 mL - 41 mL

volume of car = 5 mL

d = 10 g/ 5 mL

d = 2 g/mL

Answers

Answer:

Organisms use energy to survive, grow, respond to stimuli, reproduce

Explanation:

Three ways energy is used by the organism are food, nutrients, and sunlight.

What are living organisms?

Living organisms are those organisms that grow, adapt, and reproduce their young ones. Organisms need energy for their biological purposes. Organisms get energy from plants and other animals. This energy is used in the form of glucose.

Cellular functions require energy, which living things must obtain from food, nutrition, or sunshine. Energy is used in a cell for the transport, synthesis, and breakdown of nutrients and molecules.

Glucose and ATP are the two types of molecules that organisms primarily use for chemical energy. In the entire biological universe, both molecules are used as fuel.

Therefore, the energy is used by the organisms in three ways that are food, nutrients, and sunlight.

When do enzymes stop reacting to the substrates?

Answers

This structure is held together by weak forces between the amino acid molecules in the chain. High temperatures will break these forces. The enzyme, including its active site, will change shape and the substrate no longer fit. The rate of reaction will be affected, or the reaction will stop.

Answer:

If the reaction is divalent metal ion-dependent, you can stop the reaction by adding an excess of EDTA to bind the metal.

You can kill the protein by adding perchloric acid, then precipitate the perchlorate with an equivalent amount of potassium carbonate, leaving nothing but carbonic acid in the supernatant, which bubbles off as carbon dioxide. Centrifuge the sample and take the supernatant to analyze for the product.

A rather slow method is ultrafiltration, using a micro-centrifugal ultrafilter (e.g. Microcon) with a molecular weigh cutoff smaller than the molecular weight of the enzyme. This can be done at 4oC to slow down the reaction during the separation.
