Answer:
e) from engulfed, originally free-living proteobacteria
Explanation:
The bacterium was captured by a eukaryotic cell and then the cell evolved into the mitochondria we know today!
According to the endosymbiotic theory of the origin of eukaryotic cells, mitochondria formed from engulfed, originally free-living proteobacteria. The correct option is e.
What is proteobacteria?Proteobacteria are a major phylum (group) of bacteria. Pathogens such as Escherichia coli, Salmonella, Vibrio cholerae, Helicobacter pylori, and many others are among them.
Others are free-living, and they include many of the bacteria that fix nitrogen.
Proteobacteria, which includes mesophilic and neutrophilic bacteria, is the second largest phylum of hydrogenogenic CO oxidizers. Members of this phylum can be found in a variety of classes.
According to the endosymbiotic theory, mitochondria and chloroplasts were once free-living bacteria that were phagocytized but not digested by another cell.
According to the endosymbiotic theory of eukaryotic cell origin, mitochondria evolved from a rickettsia that was phagocytized but not digested by the larger cell.
Thus, the correct option is e.

what is the name of the simple chart that shows the flow of energy from one organism to anotherwhat is the name of a network of interconnected food chains showing the energy flow through an ecosystem
Answer:
energy pyramid
Explanation:
An energy pyramid is a model that shows the flow of energy from one trophic level to the next along a food chain.
The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. ... At the first trophic level, primary producers use solar energy to produce organic material through photosynthesis. The herbivores at the second trophic level, use the plants as food which gives them energy.

Earth, both on land and in water. Wherever they
live, plants provide food and oxygen to the
creatures that live nearby – including humans!
In this activity we will examine both a

ways they get air, food and water change along
with the environments in which they live.
Explanation:
The Galapagos island has a variety of tortoises with different physical characteristics. Can a Domed tortoise survive that lives on Isabella survive on the Island of Espanola? Explain.
Explanation:
Shell size and shape vary between populations. On islands with humid highlands, the tortoises are larger, with domed shells and short necks; on islands with dry lowlands, the tortoises are smaller, with "saddleback" shells and long necks.
Answer:
Probably not. This is because the islands at Galapagos islands are all diverse and the turtles that live on each island have characteristics that help them survive on their island and not any other island so if you were to move one of the turtles locations it probably wouldn't survive because it doesnt have the needed characteristics do survive.

Food Availability, Places to live, and water availability are all ______ of an Ecosystem.
Answer:biotic factors
Explanation:
They are living
Food availability, places to live, and water availability are all Abiotic Factors of an Ecosystem.
What are Abiotic and Biotic components?Biotic and abiotic factors make up ecosystems in which biotic factors are living things within an ecosystem such as plants, animals and bacteria, while abiotic are non-living components such as water, soil and atmosphere.
An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, the abiotic factors are temperature, light, and water. In a marine ecosystem, the abiotic factors are salinity and ocean currents. Abiotic and biotic factors work together to form a unique ecosystem.
Biotic components are living things that have a direct or indirect effect on other organisms in the environment such as animals, and microorganisms and their waste materials.
Thus, food availability, places to live, and water availability are all Abiotic Factors of an Ecosystem.

how mutation occurs on replicated DNA molecules
Answer:
When strand slippage occurs during DNA replication, a DNA strand may loop out, resulting in the addition or deletion of a nucleotide on the newly-synthesized strand. ... But if this does not occur, a nucleotide that is added to the newly synthesized strand can become a permanent mutation.
Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

5. A dedicated earth science student using
an aneroid barometer measures the air
pressure at the base of Slide Mountain
as 1016.0 mb. At the same time another
dedicated earth science student measures
the pressure at the top of the mountain.
Which pressure reading could be correct
at the top of Slide mountain?
(1) 1016.0 mb (3) 1025.7 mb
(2) 988.5 mb (4) 1040.0 mb 5
Answer:
(2) 988.5 mb.
Explanation:
The air pressure descends as we ascend. In other words, they are inversely proportional.
The air pressure descends as we ascend the mountain because the air molecules that are above us in high altitudes are fewer than the number of air molecules that are above us in the base of the mountain. So, the exerted pressure of the molecules on ourselves is lower in high altitudes.
Due to the reason mentioned above, we can deduce that the only correct option is option number two since the other ones show increasing or the same pressure, which is not possible as we ascend.
A barometer is an instrument that is designed for measuring the changes in air pressure.
The aneroid barometer has metal chamber as when the air pressure increases the walls of metal push in and when the pressure is low they come out. The chamber is connected by the springs and needle. If the pressure of the base of a mountain is about 1016.0 MB. The pressure of the top of the mountain is 1025.7 MBHence the option 3 is correct.

One is increase whereas the other is decrease in concentration.
Explanation:
This table shows that concentration of carbondioxide gas in snake's blood is higher in the blood due to respiration process but after breathing, the concentration of carbondioxide gas decreases in the blood while on the other hand, when the carbondioxide gas is lower in the blood, the concentration of oxygen increases due to loading of blood cells with oxygen in the lungs so one is increase whereas the other is decrease in concentration.

What does it mean to be in the same species
Answer:
