a. Describe the endosymbiotic theory. Explain how chloroplasts are similar to prokaryotic cells.
b. Provide observations and evidence that supports the theory.
Answers
Answer:
The endosymbiotic theory was eukaryotes that evolved to prokaryotes then to other organelles. Chloroplasts are similar to prokaryotic cells because they have a double membrane structures and more. Things that support this theories can be like I said, double membrane structures which both have and circular DNA and bacteria ribosomes too.
Explanation:
:3
Answer:
The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.
Explanation:
The exterior structure similar to bacterial cell walls" IS NOT an evidence in favour of the endosymbiotic theory. Both mitochondria and chloroplasts are double membrane bound.
Explanation:
Both the organelles mentioned in your question, are present in eukaryotic cells.
Both mitochondria (the energy producer of the cell) and chloroplast (photosynthetic machinery) have their own circular DNA . (The DNA molecules present in the nucleus of eukaryotic cells are in the form of strings and are not circular. ) We know that circular DNA is more primitive as seen in all bacteria, linear DNA definitely evolved later.

What’s the difference between weather and climate??
Answers
Answer:
Weather reflects short-term conditions of the atmosphere while climate is the average daily weather for an extended period of time at a certain location. ... Weather can change from minute-to-minute, hour-to-hour, day-to-day, and season-to-season. Climate, is the average of weather over time and space.
Explanation:
Its difference: the ladder of time,
For example: the climate is a period of many years either, temperature and humidity. We can also say as the tropical climate or equatorial climate.
And time is the state of the atmosphere at a given time and/or place, whether it be temperature, wind or pitching.

What is the end result of succession?
Answers
Answer:
The early ecologists who first studied succession thought of it as a predictable process in which a community always went through the same series of stages. They also thought that the end result of succession was a stable, unchanging final state called a climax community, largely determined by an area's climate.

Pick an environmental factors that impacts enzyme activity (Temperature , pH, or substrate concentration ) and explain how it affects the rate of the enzyme. *
Answers
Answer:
I use substrate concentration as an example
As larger amounts of substrate are added to a reaction, the available enzyme binding sites become filled to the limit of the max reaction velocity. Beyond this limit the enzyme is saturated with substrate and the reaction rate ceases to increase. This can easily be verified by observing the Michaelis-Menten law

- Habitat destruction affects all species within that habitat
- Deforestation
- Pollution decreases the chance of species surviving as they eat plastic and other pollutants and get extremely sick from it
- Nature reserves and green spaces increase the chances of certain species surviving more
- Gardens and hedgerows increase the likelihood of a species surviving by giving it a small habitat to grow in and provides a new environment to thrive in

What are the possible consequences to an organism when the temperature becomes colder than the optimum range for a species?
Answers
Answer:
Different species and individuals have different heat ... and extreme cold and heat—influence thermal tolerance.
Explanation:
hope it helps please mark me as a brainliest please
Temperature gets closer has the temperature level falls. Lower temperature levels generally result in low enzymatic activities, hence slowing down the rate of reaction. At temperature lower than the optimum temperature level, enzyme activities will effectively cease.
An organism's optimum range of clod temperature defines the the lower level temperature boundary at which an organism can withstand the effect of cold. Hence, once these range is exceeded, enzymatic activities will stop and could lead to death of not steadied on time.Therefore, cold temperature level beyond the maximum range for a specific species could lead to an halt in different system functions and possible death.

Bleeding from artery is more dangerous than that from vein, why?
Answers
Answer:
Due to the high pressure arteries hold and it is difficult to control.
Explanation:
Consider most of the arteries (minus the pulmonary arteries) have a thicker layer (lumen) that basically resists the ejection of blood from the heart. Arteries hold oxygenated blood to the vital organs (the heart itself throught he coronary arteries, the brain that needs EXCLUSIVE oxygenated blood, and lungs). Contrasted to a bleeding vein, bleeding from an artery tends to go faster, which increases the risk of hemorrhage and death.

Why is vision one of the most important sense that you can have?
Answers
Answer:
Sight and vision are important because they allow us to connect with our surroundings, keep us safe, and help maintain the sharpness of our minds. Sight and vision are different entities. Sight is physical – it is a sensory experience in which light reflects off of shapes and objects and the eyes then focus this light.

Answers
Answer:

Explanation:
The pressure exerted by air on all bodies at all times in all directions is called air pressure. When air moves at high speeds, it creates a low pressure area. The air inside a balloon exerts pressure in all directions, and makes it blow up. Air opposes the motion of a moving object.

Answers
Answer:
The trilobite is the oldest.
Explanation:
In general terms (disregarding specific examples), the lower the level in the stratosphere, the older it is. In this case, the lowest level is taken by the trilobite.
Note however, that this is not always the case, especially near edges of the plates. Sometimes plates shift, which can cause certain older fossils to be moved upwards, while newer ones are shifted downward, as one plate "eats the other". Territory creations, including valleys and mountains when plates crash into each other, can also shift where a fossil is located.

the trilobite is oldest and that's the answer

And you 1100 KG car comes informally to a stop if the vehicle is accelerating at -1.2 mL per second which force is closest to the net force acting on the vehicle
Answers
Answer:
The net force acting on the vehicle is closest to -1,300 N
Explanation:
In the question, for the car that comes to rest uniformly, we have;
The mass of the car, m = 1,100 kg
The acceleration of the car, a = -1.2 m/s²
According to Newton's second law of motion, the force, 'F', which causes a body of a given mass, 'm', to accelerate by a magnitude, 'a', is given by the following formula;
F = m × a
Therefore, the net force acting on the vehicle, [tex]F_{NET}[/tex], is given as follows;
[tex]F_{NET}[/tex] = 1,100 kg × (-1.2 m/s²) = -1320 N ≈ -1,300 N
The net force acting on the vehicle, [tex]F_{NET}[/tex] ≈ -1,300 N
