Organisms are classified into one of three domains by scientists. Which of the following characteristics is used most often to classify organisms into the proper domain?

A. genetic similarities
B. body shape similarities
C. presence or absence of photosynthesis
D. presence or absence of a cell membrane

Answers

Answer:

Most likely A. Genetic similarities

Explanation:

Because that is how you can tell they are alike and what they have in common to actually classify what family, kingdom, and domain they are in.

Genetic similarities are used most often to classify organisms into the three domains. Therefore, the correct option is A.

What are the three domains of life?

The three domains of life are Bacteria, Archaea, and Eukarya, and they are distinguished based on their genetic differences. For example, Bacteria and Archaea are prokaryotes and lack a nucleus, while Eukarya are eukaryotes and have a nucleus.

The genetic material in Bacteria and Archaea is organized differently from that in Eukarya, and they also have distinct cellular structures and metabolic pathways. Therefore, genetic differences are the primary characteristic used to classify organisms into their appropriate domain. Therefore, the correct option is A.

If the subject without diabetes eats a high-carb food such as the candy bar or orange smoothie, then the blood glucose levels will (increase/decrease/stay the same) after a three-hour digestion period.

Answers

After 3 hours of the digestion period, the blood sugar level will be SAME if the subject is NOT DIABETIC.

Diabetes is a chronic condition of high sugar levels in the blood. Diabetes is of three types -  Type 1 and 2

Type 1 - The pancreas is unable to make insulin,  required to maintain blood sugar levels. Type 2 - In this type,  the pancreas does secrete insulin but that remains insufficient for it to maintain the levels of sugar in the blood. If the subject is suffering from diabetes and eats high card food then his/her sugar levels will increase after 3 hours of digestion.

describe an experiment (using 3-5 complete sentences) that you could conduct to test whether or not humans can see in complete darkness. Make sure to include your independent and dependent variables.

Answers

Answer:

An experiment that I could conduct to test whether or not humans can see in complete darkness is by simply going into a place where I know it would be pitch black if I turned off the lights. Such as an basement or closet. I could have a friend or family member place an object close to me in the same room. Once the lights have been shut off I could easily try and find it. I have tried this experiment using a friend and myself. I could find the object just by trying to use things near me to guide myself and eventually found it. My friend on the other thought that they didn't need to use any senses to find the object but failed sadly. I say that my way of working my way to the object in the dark was most helpful because if you are familiar with your surroundings it could make things a lot easier. If you try not to use senses to help yourself in the dark things could get dangerous. You could either run into something or get hurt or end up grabbing the wrong thing.

How does the level of surface water affect the amount of water vapor in the air?

Answers

if there’s more surface water then there will be more water vapor in the air (if the climate is warm then that will also increase the amount of water vapor because warm air can hold more water )

If there’s more surface water then there will be more water vapour in the air if the climate is warm then that will also increase the amount of water vapour.

What is condensation answer?

Condensation is the method where water vapour becomes liquid. It is the knock of evaporation, where liquid water becomes a vapour.

 the air is cooled to its vapour point or it becomes so soaked with water vapour that it cannot hold any more water.

Thus, the level of surface water affects the amount of water vapour in the air.

If the "A" represents red flowers and "a" represents green glowers, what are the chances of the flowers being green?

Answers

Answer: 50%.

Explanation:

The A allele, which corresponds to red flowers is dominant, meaning if one is present, the flower is red. This generates Aa, which matches 2 squares, denoting a 50% in 4 total boxes. The a allele, corresponds to green flowers but is recessive, meaning both alleles must correspond to said trait to be expressed. 2 squares fit this scenario, making another 50% chance. Therefore, the answer would be 50%.

50% chance
if you look at the table there is
Parent one: one dominant gene parried with a recessive gene
Parent two: two recessive genes
Any time this combination happens it will always be 50%

Nicolaus Copernicus was a Polish astronomer who is best known for the theory that the sun is near the center of the universe and that the earth and other planets revolve around it. Copernicus did not believe that the planets were influenced by or revolved due to the sun; instead he believed that the sun was located near the center of the universe and that it was this center which influenced those bodies and caused them to revolve. When this theory was first published, the scientific community did not accept it. Which reason BEST explains the reason for rejection of this theory? A) It was not published until his death. B) It was not understood by scientific world. C) It lacked sufficient evidence and explanation. D) It lacked practical examples in supporting theory.

Living organisms have been classified into a large group called DOMAIN. Based on the domain classification, living organisms are either prokaryotic (without a membrane-bound nucleus) or eukaryotic (possess membrane-bound nucleus). The domains were further classified into six (6) Kingdoms viz: Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia.

Each living organisms that make up a Kingdom has its own characteristics. Based on the characteristics outlined in the attached image, it depicts that of a living organism in Kingdom Animalia because all animals are belong to the domain Eukarya i.e. are eukaryotic, multicellular and heterotrophic.

Organisms in Kingdom Animalia depend on other organisms for their food source i.e. heterotrophic. They possess more than one cell i.e. multicellular.

What is the proton-proton chain reaction? Describe this process.

Answers

it operates inside the Sun and stars of similar mass. & The proton-proton chain reaction involves the fusion of two hydrogen atoms. the similar hydrogen nuclei and fuses are combined to form the larger helium nucleus. Nuclear fission takes a larger nucleus and splits it into smaller nuclei.

Answer:

Proton proton chain reaction involves the fusion of two hydrogen atoms.

Explanation:

Two protons combine together to form a deuterium nucleus, a neutrino and a positron.

This deuterium will then combine with another hydrogen to form a helium isotope with mass number three and gamma rays.

Now two helium isotopes combine to form a helium 4 nucleus and two protons.

These two protons will once again initiate another proton proton cycle.

These are called thermonuclear fusion reactions. They are responsible for the heat and light that are received from sun .

Proton proton cycle happens in all stars primarily.

Humans directly change the dynamics of the water cycle through dams constructed for water storage, and through water withdrawals for industrial, agricultural, or domestic purposes. Climate change is expected to additionally affect water supply and demand.

Fossil fuel production is another human activity that places considerable strain on drinking water — and not just because fracking and coal mining use a great deal of water, but because their waste products can pollute groundwater, and therefore drinking water, as well.Water resources face a host of serious threats, all caused primarily by human activity. They include pollution, climate change, urban growth, and landscape changes such as deforestation. Each of them has its own specific impact, usually directly on ecosystems and in turn on water resources.
