The ones that were tested positive were milk solution and 50% egg solution.

4. Describe in your own words what we should do if the test tube for di-water tested positive for protein. (2 points)

Since Di water is our negative control, we know that there would be no proteins but if it was tested positive. Then we should start the experiment all over again this time with new, clean equipment.

4) How many milligrams are in 1,455 grams?
1,455,000 mg
145,000 mg
1,450 mg
1.45 mg
O
145 mg

Answers

1455000 ( you just multiply the mass value by 1000)

Grams can be converted into milligrams by multiplying the amount in grams by 1000. Therefore, 1455 grams will be equivalent to 1,455,000 mg. Thus, the correct option is A.

The conversion of metric units from one unit to another can be done by multiplication or division by powers of 10. If the unit is to be converted into a bigger unit, it has to be divided, whereas if the unit is to be converted into a smaller unit, it has to be multiplied.

Thus, the conversion of gram to milligram is conversion of a unit into a smaller unit and the amount, therefore, has to be multiplied.

There are 1000 milligrams in 1 gram. Therefore, 1,455 grams will have 1000 × 1,455 = 1,455,000 milligrams.

How many cells does one gram of yeast contain?​

Answers

Answer:

20 billion cells

Explanation:

It is based on the assumption that there are 20 billion viable yeast cells per gram of dried yeast. While there are 20 billion cells, you'll find that many manufacturers will state other numbers on their products.

The number of cells that one gram of yeast contain is 12 billion cells.

What are yeast cells?

Yeasts are found in soils and on plant surfaces all over the world, and they are particularly prevalent in sugary environments like flower nectar and fruits.

It is predicated on the idea that each gram of dry yeast contains 12 billion live yeast cells. Despite the fact that there are 12 billion cells, several manufacturers will list different quantities on their products.

As opposed to mushrooms, yeast is a fungus that develops as a single cell, according to Laura Rusche, an associate professor of biological sciences. Although there is just one cell in every yeast organism, these cells form multicellular colonies.

Therefore, Yeast has 12 billion cells per gram.

Why does evolutionary theory absolutely require the earth to be very
old?

Answers

Answer:

Mainly because Evolution takes millions and millions of years to happen.

Explanation:

Evolutionary theory require earth to be very old because the process of evolution takes millions of year to happen.

What do you mean by evolution ?

Evolution is the process through which a population of organisms evolves as new generations replace ancestors. Individual species do not evolve; rather, communities of organisms do.

Natural selection processes like as environmental change, predation, or human disturbance create evolutionary adaptations, and these processes must continue and grow widespread for the change to remain and accumulate. That happens less frequently and slowly than you may expect.

Scientists have determined that Earth is 4.54 billion years old, with a 50 million year error, by dating the rocks in its ever-changing crust as well as those in Earth's neighbors, including the moon and passing meteorites.

Therefore, the Earth needs to be very old for evolutionary theory to be true.

Explanation:

Energy in a battery is used act as chemical energy that gives power to an electronic device along wires.

Energy of laptops battery transformed to light, heat and sound energy when left overnight without being charged. Light energy can be seen when laptop left turned on, laptops also creates sounds due to intense vibrations as the system is turned on and chemical energy is utilized, and when chemical energy converted into heat energy and the system get heat up.

Hence, the correct answer is "It was transformed to light, heat and sound energy."

During cell reproduction, chromatin fibers coil up into structures called

a. chromosomes
b. lysosomes
c. nucleoli
d. ribosomes

Answers

it is a. chromosomes

During cell reproduction, chromatin fibers coil up into structures called chromosomes. Therefore, the correct option is A.

What are chromosomes?

Chromosomes are structures made up of DNA and proteins that are found in the nucleus of the cell. They contain genetic information That are responsible for the inherited characteristics of the organisms such as eye color, hair color, height etc.

Chromosomes play a crucial role in cell division, as they ensure the proper distribution of genetic material to the daughter cells.

During cell division, chromosomes are replicated and then separated into daughter cells, ensuring that each cell receives a complete set of chromosome.

The number and arrangement of a chromosome vary depending on the species, but all human cells except the sperm and egg cell contains 23 pairs of chromosomes. Hence, the correct option is A.

Diffusion is the movement of molecules from an area of high concentration of molecules to an area with a ____ concentration.

A. Equal
B. Higher
C. Lower
D. None of the above

Answers

Answer:

lower

Explanation:

Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. So, the correct option is C.

What is diffusion?

Diffusion is a type of passive transport, this means that it does not require any kind of external energy for movement of molecules. The difference in concentration in two areas gives rise to a concentration gradient. Where, in one area there is high concentration of molecules and in another, there is low concentration of molecules.

If the molecules move from an area of higher concentration to an area of lower concentration, they are moving along the direction of concentration gradient. This is why no additional energy is required. Diffusion is a type of passive transport where molecules move along a concentration gradient.

This is in contrast to active transport where molecules move against the concentration gradient and therefore require external energy.

Therefore the correct option is C.

Every single cell organism is able to survive because it carries out

Answers

Every single celled organism is able to survive because it carries out metabolic activities. Metabolic activity is a set of chemical reactions which are needed for an organism to maintain it's life.

Every single cell of an organism is able to survive independently because it carries out metabolic processes at its own.

What is Metabolism?

Metabolism can be defined as the chemical changes or reactions which take place in a cell or an organism. These changes make energy and the compounds which cells and organisms need to grow, reproduce, and stay healthy.

Metabolism is divided into two classes: anabolism and catabolism.  Anabolism involves the synthesis of a complex compound from simpler or smaller molecules or atoms. Catabolism involves the breakdown of a complex molecule into smaller and simpler ones.

Living organisms are able to perform the metabolic processes such as respiration, excretion, reproduction, and digestion which is a distinguishing factor from that of non-living organisms.
