what did the large prokaryotic cell provide the mitochondria and/or chloroplast ancestors?
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.

Which of the following best explains how a dog is able to ingest and digest food, and remove waste
products from its body?
Choose 1 answer:
A dog carries out digestion and excretion through a series of redundant systems, so if one
system is injured, another will take its place.
A dog has cells whose genetic makeup can change depending on the circumstances, such as
whether the animal is ingesting and digesting food, or excreting waste.
A dog has systems of specialized cells, such as those that make up the urinary tract and
digestive system, that help it carry out these functions.
Answer:
1st is correct
Explanation:
At its simplest, a dog's digestive system is a long tunnel that runs from their mouth to the anus. Food goes in at the mouth and travels through this tube and at various stages is broken down and either absorbed into the body or excreted as waste at the anus.
Drea is comparing three organisms. Two have many of the same characteristics. But they have very few characteristics in common with the third organism. What can Drea infer about the relatedness of these three organisms?
Group of answer choices
The first two are unrelated, but each is related to the third.
Relatedness of the three organisms depends on the characteristics the first two share.
The first two are more closely related to each other than they are to the third.
The first two are equally related to the third.
Answer:
The first two are more closely related to each other than they are to the third.
Explanation:
The question tells us that the first two organisms share many common characteristics with each other, this tells us that the first two are related. We can cross out answer choice a. The question also tells us that the first two have very few characteristics in common with the third organism. With this much info given, the answer choices left are:
Relatedness of the three organisms depends on the characteristics the first two share.The first two are more closely related to each other than they are to the third.The first two are equally related to the third.First choice doesn't make any sense, there is no correlation between the common characteristics of the first two with the 3 organisms as a group.
Second choice makes sense and logical.
Third choice is wrong since the question does not give us enough information to know the first two is equally related to the third.
The first two are more closely related to each other than they are to the third. Is the right answer.

A new microbiology student failed to properly sterilize the pipet between creating E. coli and S. epidermidis cultures from the tablets in the lab kit. How would this mistake be recognized when the mixed culture is streak plated
With this error, the culture medium can be visualized with two different types of bacteria, with different stains.
In addition to staining in culture medium, what are the differences?Escherichia coli, or E. coli, is a bacterium that naturally inhabits the intestines of people and some animals, without any signs of illness.
Staphylococcus epidermidis is a Gram positive, coagulase negative bacterium that is part of our normal flora. The microorganism colonizes human skin and mucous membranes, notably moist surfaces such as armpits, nostrils, etc.
With this information, we can conclude that this error, the culture medium can be visualized with two different types of bacteria, with different stains.

explain how weather,climate,and seasons could affect the biotic and abiotic factors of an ecosystem
Weather, climate and seasons are factors that limit the distribution of different species of living beings in ecosystems, influencing survival and reproduction.
What are the biotic and abiotic factors of an ecosystem?Biotic factors are each of the living organisms of an ecosystem and abiotic factors are all non-living ones such as organic and inorganic substances in the system as well as environmental conditions.
Weather, climate, and seasons could affect these factors in altering the distribution of species, but would also decrease primary production, which would affect survival and growth.
Therefore, we can conclude that the weather, climate and seasons are factors that limit the distribution of different species of living beings in ecosystems, influencing survival and reproduction.
