Spontaneous generation is the idea that new living organisms can form from nonliving matter. Cell theory, however, states that cells
can only grow from other cells.
Which of the following experimental results supports the idea that new cells can only form from other cells?
A. A plant cell had its cell wall broken, and the cell was found to no longer be able to function.
OB. A piece of uncovered meat that was left outside contained maggots by the end of one day.
OC. A container of soup that was heated and sealed did not grow mold even after several months.
OD. A mold sample examined under a microscope showed a regular structure made of many individual cells.

What is harsh winter ?
Harsh climates or conditions are very difficult for people, animals, and plants to live in.
How Does a Harsh Winter Affect Wildlife?
A snowy winter can alter migration patterns, make foraging for food difficult and make a typical environment uninhabitable.
How do animals rely on their natural environment?
This ecosystem is its natural habitat. This is where the basic needs of the organism to survive are met: food, water, shelter from the weather and place to breed its young. All organisms need to adapt to their habitat to be able to survive.

Answers
Answer:
the kind of material it is moving through
Explanation:
Sound wave is a type of mechanical wave, which requires a medium to travel, unlike longitudinal waves that can travel through vacuums. Since, sound waves travel through mediums, the KIND OF MEDIUM/MATERIAL it is traveling through has a role to play on how fast it moves.
Sound waves move faster in materials whose molecules are closely packed together than those with loosely packed molecules. This is why sound waves naturally travel faster in SOLID materials. Therefore, the the kind of material the sound wave is moving through affects how fast it moves.

Explain enzyme-substrate specificity.
Answers
[tex]\purple{\tt{\huge{Answer}}}[/tex]
substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.
Answer:substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.
Explanation:Enzymes and substrates share specificity in that an enzyme will only react with a specific substrate • This is because the active site is complementary in both shape and charge to a given substrate • The model by which this is known is ‘lock and key’ as the substrate is a precise structural fit for the enzyme, much like a lock and key • When the enzyme and substrate bind, they form an enzyme-substrate complex, before the substrate is catalytically converted into a product

C. Every organism has the same genetic sequence
d. All populations look identical within a species
Answers
Answer:
A
Explanation:
Has to be the same family to be genetic and you have to find which has the most variety
Different skin color within a species is an example of genetic biodiversity. Therefore, option (A) is correct.
What is genetic biodiversity?
Genetic biodiversity refers to the variety of genes and genetic traits that exist within a population or species. It is a fundamental aspect of biodiversity, as it underpins the ability of species to adapt to changing environmental conditions and to maintain resilience in the face of threats such as disease, climate change, and habitat loss.
Genetic biodiversity arises from mutations, genetic recombination, and other processes that generate new genetic variation within populations. This diversity provides the raw material for natural selection to act upon, allowing organisms with advantageous traits to survive and reproduce.
Genetic biodiversity is important for ecosystem functioning and for the conservation of species, as it helps to ensure that populations are able to adapt to changing conditions and maintain their long-term viability. The loss of genetic biodiversity can have significant negative impacts on populations and ecosystems, making it an important focus of conservation efforts.

3.) Cilia function like a filter, trapping dust and pollen in the nose,
4.) Mucus traps bacteria and viruses to be removed or swallowed.
Explanation:
Coughing involves a quick contraction of the diaphragm muscle, forcing air out while the cilia act like a filter, trapping dust and pollen in the nose. Mucus traps bacteria and viruses to remove or swallow. So, the correct options are A, C and D.
What is Respiratory system?The respiratory system is defined as the network of organs and tissues that help us breathe which includes the airways, lungs, and blood vessels. The muscles that power the lungs are also part of the respiratory system where these parts work together to move oxygen throughout the body and clear out waste gases like carbon dioxide.
Respiratory system works in that way with the immune system by keeping the human from getting sick by bacteria and viruses are removed or swallowed by mucus, while the cilia act like a filter, trapping dust and pollen in the nose.

what is a roan color in cattle is controlled by codominant genes for both red and white hair. if a roan cow is crossed with a white bull, what percentof offspring would be white?
Answers
Answer:
50%
Explanation:
Roan color is controlled by two codominant alleles. Let us assume that the red color allele is R and the white color allele is W. Thus, the roan color would be RW.
Roan color cow is crossed with a white bull;
RW x WW
RW RW WW WW
RW = roan = 50%
WW = white = 50%
1/2 or 50% of the offspring would be roan color while the remaining 1/2 or 50% would be white in color.
