An experiment was conducted to determine which type of fruit attracts the most fruit flies. Equal sized pieces of apple, pear, and banana were placed in separate containers at different areas around the school. The containers allowed the fruit flies to enter, but the fruit flies were unable to escape. After one day, observations were made by the students. Which best describes an error the students made in the experiment? A) too many types of fruit were used B) fruit flies were unable to escape C) different areas around the school were used D) one day is not long enough for the experiment

Answers

Answer 1

Answer:

C

Explanation:

The error that the student made was to place the containers for the different fruits in different areas around the school.

In order to ensure that each contain receives the same treatment, they should have been placed in the same area around the school. Different areas around the school might have varied populations of fruit flies, hence, jeopardizing the result.

The containers should have been subjected to the same conditions in order to ensure an unbiased outcome.

The correct option is C.

Gravity is creating a downward force that is equal to the force of the table pushing up. There are balanced forces (gravity and upward push of table) holding the ball in place.

Answer:

Unbalanced

I cant really explain this from the top of my head but i do know that if the forces were the same, the objects velocity will remain constant, but if the forces are unbalanced it will either slow down or speed up the objects velocity. an example would be tug of war i guess

What do all living cells have in common? 1. A cell membrane and genetic material 2.Chloroplast and mitochondria 3. A cell wall and cell membrane 4. A nucleus and genetic material

Answers

Answer:

one.

Explanation:

nuclei aren't present in prokaryotes, a cell wall/chloroplasts are a part of plants. the basic beings just need a cell membrane (to separate it from it's environment) genetic material, to get information to code proteins, and ribosomes, to create proteins.

All living cells have a cell membrane and genetic material. The correct option is 1.

A cell membrane, also known as the plasma membrane, is a fundamental feature of all living cells.

It is a thin, flexible barrier composed of lipids and proteins that surrounds the cell and separates its internal contents from the external environment. The cell membrane regulates the passage of molecules, ions, and other substances in and out of the cell, maintaining an internal environment necessary for cellular processes.

Genetic material refers to the hereditary material that carries the genetic instructions for the functioning, development, and reproduction of living organisms.

In most cells, the genetic material is in the form of deoxyribonucleic acid (DNA).DNA contains genes, which are specific sequences of nucleotides that encode the information necessary to build and maintain an organism.

All living cells have a cell membrane that serves as a boundary and a genetic material, usually in the form of DNA, that carries the instructions for the cell's functioning and inheritance. These two components are essential for the basic structure and processes of all living cells.

Thus, the correct option is 1, A cell membrane and genetic material.

Will water that contains no solute ever stop flowing into a hypertonic solution through osmosis?

Answers

Answer:

No, it will never stop flowing

Explanation:

Osmosis is the movement of water from an area of lower concentration of solute to an area of higher solute concentration through a semi-permeable membrane. If one side of the membrane is completely free of solute, water will move to the hypertonic solution continuously in a bid to achieve equilibrium until all the water completely moves to the hypertonic side. This is because equilibrium cannot be attained since one side is completely void of solute and another has solutes.

It is like having red coloured paint on one side and water on another side of a membrane, and the water moves into the paint compartment and only stops when they both have the same color. No matter how much water moves across, they cannot have the same color on both sides.

O to provide a standard system of measurement
O to establish a point from which to measure future distance, or if movement has occurred
O to determine the speed of an object in miles per hour
O to provide a standard from which to evaluate variables in an experiment

Answers

A: to establish a point from which to measure future distance, or if movement has occurred.

(i do not know the exact definition, so my apologies if this is incorrect, however i do have an explanation)

using process of elimination, we can cross out the 1st, 3rd, and 4th option, as they do not logically make sense:
1 - a reference point is not a system of measures, hence the word ‘point’.
3 - a reference point is again, not a measuring tool or system
4 - at a glance this may make sense, but a reference point is just that, a reference, it’s something you can go back to to see if your work is accurate or has changed in some way, thus option 2 is the best answer.

C.) mitochondria
D.) chloroplasts

Answers

Answer:

Ribosomes

Explanation:

Prokaryotic cells do have a primitive form of ribosomes. Thus, the correct option for this question is A.

What are Prokaryotic cells?

Prokaryotic cells may be defined as the types of cells that lack a well-defined nucleus and other membrane-bound cell organelles. The genetic material of a prokaryotic cell is a single chromosome made up of a single strand of DNA.

A Prokaryotic cell typically has a cell membrane or plasma membrane that functions or operates like a protective cover. Golgi apparatus, mitochondria, and chloroplasts are significantly absent in prokaryotic cells. This is because they are membrane-bound cell organelles.

The traces of ribosomes are required for the process of protein synthesis in order to accomplish metabolic activities required for the survival of prokaryotic organisms.

Therefore, prokaryotic cells do have a primitive form of ribosomes. Thus, the correct option for this question is A.

How do particle speed relate to the distance between particles

Answers

Answer:However, particles will move in straight lines until they collide with something. Collisions usually change the speed and direction of the particles movements. If the motion of particles slows the particles move closer together. This is because the attraction between them pulls them toward each other.

Explanation:

Larger particles move slower, due to their larger mass and may be influenced by numerous collisions with many nearby smaller particles. Smaller particles move faster. ... Hotter particles move faster because they have more energy. The rate of diffusion increases as temperature increases because the particles move faster. You're welcome :) - xoxo madster
