How is destiny calculated given mass and volume

Answers


Divide the mass by the density of the substance to determine the volume (mass/density = volume). Remember to keep the units of measure consistent. For example, if the density is given in grams per cubic centimeter, then measure the mass in grams and give the volume in cubic centimeters.

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.

Answers

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

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.

Which statement describes why hypotheses are valuable, even if incorrect? Select one: a. Adds to existing knowledge b. Answers a defined problem c. Allows theories to be proven d. Allows theories to be disproved A theory doesn't get disproved without large amounts of da

Answers

Answer:

The correct option is a: "Adds to existing knowledge"

Explanation:

A hypothesis is an idea that is brought forth based on an observation. It needs to be tested by carefully and thoroughly planning an experimental design that either supports or refutes the hypothesis. So even if it comes out to be incorrect, it still allows us to understand some aspect of a phenomenon that was unknown till then.

What is the purpose of a reference point?
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.



How was genetic engineering able to solve the problem of tomatoes being damaged in transit without sacrificing taste?

What was the problem with this genetic engineering solution?

Answers

Answer:

The genetic engineering produced on these tomatoes was the solution to reduce the amount of chemical usage to crops as well as introducing a greater disease resistance, insect resistance, and increase shelf life. Conclusively, scientists and farmers still wanted to keep their natural color and flavor, yet change it into a more positive way. 70 years ago, spoke of the dangers of nightshade foods, covering all this ground, and stating that traditionally in South America, where potatoes and tomatoes come from they were eaten as medicine – that is given specifically for a short period time for a specific condition.

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

The responsibilities of the federal government were clearly defined and generally limited to national duties such as defense, border maintenance, and international trade. In the 1930s, federalism shifted to a more cooperative system, often called marble cake federalism because the lines of responsibility between the federal government and the states became unclear. Considering the benefits and drawbacks of the current system, should the federal government and the states continue in the same partnership, or move back to a dual system?
