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 1

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.

Explanation

sorry if I went overboard I tend to write a lot.

Cells in the body take in nutrients and produce wastes. After the wastes leave the cell, what structure do they
enter?

1. Another cell
2. A capillary
3. The digestive system
4. The kidney
5. The lungs

Answers

Answer:

The Digestive System

Explanation:

Most nutrient absorption occurs in the small intestine. Nutrients are absorbed through its walls into the circulatory system and by the time the chyme exits the small intestine, only water and undigestible substances are left behind. The chyme then enters the large intestine. (Or The Digestive sytem anways)

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.

Answers

Answer:

B

Explanation:

The answer is B because the scientific community didn't see or have any practical evidence to show that Copernicus was right so they rejected the heliocentric theory.

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.

B.
Photosynthesis uses oxygen and carbon dioxide, and releases water.

C.
Photosynthesis uses water, and releases carbon dioxide and oxygen.

D.
Photosynthesis uses oxygen, and releases carbon dioxide and water.​

Answers

the answer is A because that’s the only thing plants “breath”

The process by which green plants and some other organisms use sunshine to create meals from carbon dioxide and water is called photosynthesis. Therefore, option (A) is correct.

What is photosynthesis?

Photosynthesis is the process by which green plants and some other species use sunlight to create food from carbon dioxide and water. Other organisms may also participate in this process. Chlorophyll, a green pigment, is typically involved in the process of photosynthesis, which results in the production of oxygen as a byproduct in plants.

Photosynthesis takes place in the chloroplast, a specialized intracellular organelle found in plants and algae, which emerged considerably later. During the day, photosynthesis is carried out by chloroplasts. The photosynthetic cells use NADPH and ATP, the direct results of photosynthesis, to make a variety of chemical compounds.

C Eastern mole and side-striped jackal, because they have specified dietary needs.

D Side-striped jackal, red fox, and coyote, because they have shared physical characteristics.

Answers

Answer:

Kingdom Animalia

Explanation:

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.

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.

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%

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.
