A hypothesis is a plausible explanation for a particular fact, observation, or process. Write a hypothesis about how the various concentrations of acid will affect the amount of limestone that is dissolved from each jar.

Answers

The hypothesis will state as follows: IF the concentration of acid increases, THEN, the amount of limestone dissolved will also increase.

WHAT IS A HYPOTHESIS?

A hypothesis is a crucial part of the scientific method. It is a testable explanation of an observation or a proposed answer to a scientific question.

A hypothesis, which must be testable via experimentation, can either be accepted or rejected depending on the outcome of the experiment.

A hypothesis is an IF, THEN statement that must include the independent and dependent variables of the experiment i.e. it must show how the dependent variable (effect) is affected by the independent variable (cause).

Which of the following statements about eukaryotic RNA is true?

O -The modified RNA molecule is transported into the nucleus.

-Exons are spliced together.

-Introns are not transcribed from DNA to RNA.

Answers

Answer:

A small cap of extra nucleotides is added to both ends of the RNA

Hope you like it

Thank you ❤️

The statement 'exons are spliced together' is TRUE. The exons are the coding regions of genes.

RNA splicing is a eukaryotic mechanism by which non-coding sequences of genes called 'introns' are removed from the precursor messenger RNA (pre-mRNA), whereas protein-coding sequences called 'exons' are spliced together.

These gene coding sequences (exons) are spliced together by a macromolecular complex known as the spliceosome.

In consequence, a pre-mRNA is converted into a mature mRNA, which is subsequently used for protein synthesis.

In conclusion, the statement 'exons are spliced together' is TRUE.

An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone.

True

False

Answers

Answer:

The answer is true.. it is attached to the carbon backbone.

The statement "An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone" is definitely true.

What is Unsaturated fat?

Unsaturated fat may be defined as a kind of fat carrying a high proportion of fatty acid molecules with at least one double bond. This type of fatty acid is considered to be healthier in the diet than saturated fat.

An unsaturated fat generally contains almost all of the hydrogen atoms which are directly attached to the carbon backbone in a series of systematic arrangements.

Unsaturated fat is typically fatty acid that remains liquid at room temperature and comes from a plant, such as olive, peanut, corn, cottonseed, etc.

Therefore, the statement "An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone" is definitely true.

Ways in which biology, technology, and society are connected?

Answers

Biology and technology are connected in many ways and virtually everything will eventually affect society in some way or another. The technological advances of biology are currently having a massive effect on society due to the length of people's lives increasing. It is now common for people to live well into their 80's and 90's which is mainly due to new medications and treatments that can prevent and cure disease and infection. Most of the elderly will have a concoction of medications it is necessary for them to take on a daily basis in order for them to live happy and fulfilling lives. 50 years ago this would not have been available and they would have died much younger.

Technology and biology
The Technological advancement towards a cure for cancer seems to be getting closer every day. More and more people are now surviving cancer which was previously such a massive killer in people of all ages. Immunization is now available for every single person in developed countries so diseases are less common. Sanitation is now much better so illnesses that were previously caused by ill health, dirt and germs are now much lower because we are not exposed to such things on a daily basis.

This is all fantastic news as it living longer is something that virtually everyone wants.

Advancements and society
We want to get the most out of our lives and live a long and fulfilling life. But many countries are now struggling to cope with the increase in elderly people who need help and support from the government in order to survive. Many elderly people need people to care for them or do not have enough money to live and no way of working to provide themselves with an income. Pension plans, hospital care and home nursing care must be provided for the people who cannot afford it themselves and this is a massive drain on the economy and has a knock on effect to society and effects us all.

c. Operant conditioning
d. Extinction

Answers

Answer:

Explanation:

Ricky has been struggling to sleep due to the loud noise of police sirens at night, but has noticed that the sirens have been disturbing his sleep less as he gets used to the noise. Ricky is experiencing habituation.

What is habituation?

habituation is a type of response where complete elimination of a particular response or  zero frequency of occurrence occur.

If the stimulus continues  for an additional number of trials, although no changes occur but  the response will exhibit lower levels of recovery.

Habituation is a non-associative learning in which an automatic decrease in the intensity of a response occur which is repetitive, weak stimulus, without serious consequences, for example, ignoring stimuli

Habituation defines as  the fading of the response over the course of monotonous stimulation, and sensitization refers to processes of increased response.

It is true that inorganic compounds include carbon dioxide, oxygen, water, and most ionic compounds.

What are inorganic compounds?

Any substance in which two or more chemical elements usually other than carbon are combined, almost always in definite proportions, is an inorganic compound.

When carbon is bound to hydrogen, the compound is classified as organic.

Organic compounds are distinguished by the presence of carbon atoms. Most inorganic compounds do not contain carbon atoms.

Water, sodium chloride (salt), sodium bicarbonate (baking soda), calcium carbonate (dietary calcium source), and muriatic acid are examples of common inorganic compounds (industrial-grade hydrochloric acid).

Inorganic compounds are characterized by high melting points and varying degrees of electrical conductivity.

Answer:

tritium

Explanation:

a hydrogen atom with:

1 proton 0 neutrons = hydrogen

1 proton 1 neutron = deuterium

1 proton 2 neutrons = tritium

If the hydrogen has a mass of three, then it would be tritium

What it would be?

An atom of hydrogen with an atomic number of one and a mass of three would be a hydrogen isotope called tritium.

Regular hydrogen (also known as protium) has one proton and no neutrons, giving it a mass of approximately 1 atomic mass unit (amu). Tritium, on the other hand, has one proton and two neutrons, giving it a total mass of about 3 atomic mass units (amu). This makes tritium a heavier and less common isotope of hydrogen.

Answers

The breakdown of fat produces: b. more than twice the amount of energy than the breakdown of carbohydrates.

Biological macromolecules can be defined as a very large molecule (structure) that comprises of covalently bonded organic atoms and smaller molecular structures (monomers).

Biological macromolecules are organized into four (4) main categories and these includes;

I. Nucleic acid: it comprises of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) which are the genetic codes (blueprints) for living organisms.

II. Carbohydrates: it is contained in energy-giving foods and it aids the functioning of the muscles, nervous system and other organs found in the body.

III. Proteins: it contains amino acids and it is responsible for maintaining the functioning of the body system.

IV. Lipids: these categories of biological molecules is mainly made up of fats and it is responsible for providing the body with long-term energy.

In Biology, lipolysis is a process which typically involves the breakdown of fat into glycerol and fatty acids, so as to produce the energy required by a living organism. Thus, the fatty acid that are produced during these process are released into the bloodstream of the living organism and transported to the tissue that uses the energy.

Generally, the breakdown of fat produces more than twice the amount of energy than the breakdown of carbohydrates because it provides long-term energy that is required by the body of living organisms to function properly.
