The answer to the question stated above is letter c. Pasteur tested for microorganisms, but Redi studied larger organisms.

Redi experimented with rotting meat; Pasteur experimented with broth. Redi disproved spontaneous generation for large organisms by illustrating that maggots arose from meat only when flies laid eggs in the meat. Pasteur used his famous swan-neck flask experiment, to end the debate. On his experiment air is allowed to contact the broth. Microbes present in the dust were not able to navigate the tortuous bends in the neck of the flask.

If you were planting a vegetable garden, what should you consider for the time of planting?

zvonat [6]

When planting vegetables it is very important to know the climate of the area, its usual patterns, and how will that affect the growth and development of the crops. The soil quality too is very important, as it is the basis for the development of the root-stock of the crops.

If we have a temperate type of climate, than we have four different seasons, meaning different weather patterns throughout the year. We can take onions, radish, and peppers as vegetables of choice. The onions can be planted in mid-autumn, as they will need more moisture, and they are resilient to low temperatures, thus will not have problems in the winter, and in the spring they will already have the basis so will grow quickly and be larger. The radish can be planet in late winter or early spring, in a period when there is more precipitation. It is not a vegetable that likes high temperatures, so with its quick development, it will be able to develop the tuber by late spring. The peppers can not sustain low temperatures, so they should be planted in late spring. They also like warm weather and lot of water, so it will be needed to water them a lot in the hot and dry period. They will manage to develop and produce the vegetables by the end of the summer, thus not getting damaged by the cold nights in the autumn.

How do evolutionary psychologists use natural selection to explain our human behavioral tendencies?

Naya [18.7K]

Our genetic predispositions and our surrounding environments interact. Evolutionary psychologists seek to understand how our traits and behavior tendencies are shaped by natural selection, as genetic variations increasing the odds of reproducing and surviving are most likely to be passed on to future generations.

The same sentences are written with a substitution, deletion, or insertion, much as a gene may have a substitution, deletion, or

strojnjashka [21]

Answer:

The question is incomplete, the complete question has been added as an attachment.

THE DGR AN represents deletion mutation

THE RED ANA TRA N represents insertion mutation

THE FOX WTS RED represents substitution mutation

Explanation:

Mutation is a change in the nucleotide sequence of a gene. It can be of different types depending on how it occurs. A deletion mutation is that which involves the removal of one or more nucleotide base from the sequence.

An insertion mutation is the addition of one or more nucleotide bases to the sequence.

A substitution mutation is the replacement of one or more nucleotide base in a sequence.

The original sentences were:

1. THE RED ANT RAN

2. THE FOX WAS RED

3. THE DOG RAN

The three sentences that mutated/changed are:

1. THE DGR AN- in this sentence, letter O which represents one base is missing due to removal, making the original sentence (THE DOG RAN) alterated. Hence, this represents an example of deletion mutation.

2. THE RED ANA TRA N - in this case, Letter A has been added in between N and T. This makes the original sentence (THE RED ANT RAN) altered. Since addition of letter (base) occurred, this represents an example of insertion mutation.

3. THE FOX WTS RED - In this case, letter A in "WAS" was replaced by T, making the original sentence (THE FOX WAS RED) altered. Since a replacement of letter (base) is the case here, it represents an example of substitution mutation.
