Answer:
Show that life can only come from life (rather than spontaneous generation)
Explanation:
Pasteur boiled a broth in a flask with an S-shaped neck. Thebend in the neck prevented particles from the air reaching the broth, but still allowed air to get in. No bacteria grew in the flask.
When the flask neck was broken so that particles could get inside, the broth became cloudy, showing that microorganisms were only able to grow from other living things from the outside, and not spontaneously from nothing

During cell reproduction, chromatin fibers coil up into structures called
a. chromosomes
b. lysosomes
c. nucleoli
d. ribosomes
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.

Provide evidence to support the claim that viruses fall on the border between living and nonliving.
Answer:
Just like living organisms, viruses use genetic material such as DNA or RNA, but unlike living things, they cannot reproduce using mitosis, binary fission or meiosis. Instead, they simply insert the genetic material into a living cell and then replicate their genetic material along with the cell's in order to create more viruses.

producing offspring
Reproduction is the process of producing offspring, whereas heredity is the process
of passing on traits.
Reproduction always involves changes in inherited characteristics, whereas heredity
does not
Heredity always involves changes in inherited characteristics, whereas reproduction
does not
Answer:
Reproduction is the process of producing offspring, whereas heredity is the process
of passing on traits.
Explanation:
PLEASE MARK BRAINLIEST, if you think this is correct and best! Thanks!
Reproduction generally means making copy of something, like giving birth/breeding, duplicating.
Heredity is inheritance of traits/ passing on traits from parents t thsir child/children through genes. It makes children have same traits as their parents and looks so what same like their parents!
They definitely aren’t same!
Reproduction is the process of producing offspring, whereas heredity is the process of passing on traits.
What do you mean by heredity?Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information.
Heredity explains why offspring resemble, but are not identical to, their parents and is a unifying biological principle. Heredity refers to specific mechanisms by which characteristics or traits are passed from one generation to the next via genes.
Heredity can be defined as the transfer of genetic characters from parents to offsprings by the process of fertilization, where the nuclei of male and female gamete fuses with each other and forms the genetic material of the zygote.

How many cells does one gram of yeast contain?
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.

how would you relate force and acceleration?
Force = mass * acceleration
This is Newton's second law
Explanation:
Hey there!
The external agency that brings change in body's action(i.e changes the body from rest to motion or motion to rest) is called a force.
We know;
The force is inversely proportional to acceleration. So, the best method to relate them is force in inversely proportional to acceleration of a place.

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
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.

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

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
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.
