Which of the following groups of cellular components are found in eukaryotic cells but not prokaryotic cells?
Answer:
mitochondria is found in eukaryotic cells but not prokaryotic cells
Prokaryotes lack mitochondria, There are no prokaryotic cells without mitochondria. The nucleus and the Golgi apparatus are examples of additional membrane-bound structures.
What is the cellular component of prokaryotic cells?All prokaryotes have DNA, ribosomes, cytoplasm, and plasma membranes but no membrane-bound organelles. Polysaccharide-containing capsules are also typical. Diameters of prokaryotic cells range from 0.1 to 5.0 m.
In the cells of almost all eukaryotic organisms, including plants and animals, are mitochondria.
Cells that require a lot of energy, such as muscle cells, can be seen to have many mitochondria. Red blood cells are one sort of cell that doesn't have any mitochondria at all.
Therefore, mitochondria are found in eukaryotic cells but not prokaryotic cells.

purchasing habits affect her ecological footprint?
A.Yes, because the resources used for transporting food are included in the ecological footprint
B.Yes, because local farms likely take up more space and use more resources than farms elsewhere.
C. No, because she is eating the same foods as before.
D. No, because local faros likely take up the same amount of space as farms elsewhere.
Answer:
The correct answer is - option A.
Explanation:
The ecological footprints can be understood simply by that it is an activity that is measured to produce a product in terms of consumption of resources like land or water and other resources.
Purchasing a specific type of food from local farms does not affect the ecological footprint of vera. Transportation is also included in the ecological footprint as it is also counted as one of the resources required.

is hydrogen sulfide an organic molecule
Answer:
no
Explanation:
Answer:
No
Explanation:
Organic compounds are those that contain carbon-hydrogen bonds, i.e. we can say that all organic compounds are made up of carbon and hydrogen, as well as other elements if the molecule contains them. In H2S , it is hydrogen sulfide, and no carbon is present, and so it cannot be an organic compound.

What do you think would happen to a jellyfish if it were placed in a freshwater lake?
A jellyfish would die if it was placed in a freshwater lake. Water would enter the jellyfish's cells, causing them to swell and eventually burst.
hope this help. :)
[ It's basically the same answer that someone else put, just with a little bit more information. ]
A jellyfish would die if it was placed in a freshwater lake. Salt water has more solutes than freshwater, so a freshwater environment would be hypotonic to a jellyfish's cells. Water would enter the jellyfish's cells, causing them to swell and eventually burst.

What effect did the increase in atmospheric oxygen by photosynthetic organisms have on Earth in terms of the geosphere?
Answer:
hope it helps you❤❤❤
Explanation: But roughly 2.45 billion years ago, the isotopic ratio of sulfur transformed, indicating that for the first time oxygen was becoming a significant component of Earth's atmosphere, according to a 2000 paper in Science. At roughly the same time (and for eons thereafter), oxidized iron began to appear in ancient soils and bands of iron were deposited on the seafloor, a product of reactions with oxygen in the seawater.
Most important, how did the amount of atmospheric oxygen reach its present level? "It's not that easy why it should balance at 21 percent rather than 10 or 40 percent," notes geoscientist James Kasting of Pennsylvania State University. "We don't understand the modern oxygen control system that well."
The growth of microbial metabolism was aided by an increase in atmospheric oxygen.
What is a photosynthetic organism?Photosynthetic organisms have been considered as an autotroph, able to produce organic substances from inorganic nutrients based on energy harvested from light.
Despite the fact that minuscule cyanobacteria were supplying the gas as a side effect of photosynthesis, Earth's first air and oceans were devoid of free oxygen. Around 2.4 billion years ago, the amount of oxygen in the atmosphere unexpectedly increased by several orders of magnitude in approximately 200 million years.
Atmospheric oxygen is the outcome of a change in a microbe's metabolism that occurred once in the earth's history.

How does a population's growth rate change as it goes through the phases of logistic growth?
A population increasing according to logistic growth normally has three phases in which the population is near to its limiting population due to intra-species conflict.
What is logistic growth?In 1845, Pierre Verhulst used the term logistic growth to describe a type of population expansion. A graph with time on the x axis, and population y axis, can be used to depict it. The curve's exact form is determined by carrying capacity and maximum growth rate, however all logistic growth models are s-shaped.Phases of logistic growth curve:-The beginning population, carrying capacity, and maximum population growth rate are all factors in a logistic growth model. The beginning population is self-explanatory the carrying capacity is the maximum population that can live in the environment and the maximum rate of growth is how quickly the population can develop if no limitations exist for example, a rabbit population can grow a lot faster than a human populationThe First Stage of Logistic Growth
A logistic growth model's early phase is generally steady or flat over time.Logistic Growth in the Middle Phase
The pace of growth may alter beyond the first period, based on the connection between the beginning population and the carrying capacity. The population grows fast if the original population is substantially lower than the carrying capacity. If the population is significantly bigger than the carrying capacity, the population will rapidly decline, for example, after some ecological devastation reduces the carrying capacity.The population will be steady if the original population is near to carrying capacity.Logistic Growth's Final Stage
When the population reaches or approaches carrying capacity, the final phase of logistic expansion occurs. Until the carrying capacity changes, the population stabilizes at this stage.To know more about logistic growth curve here

What is a volcanic eruption?A volcano is a hole or rupture in the surface of the earth through which gases, volcanic ash, and hot liquid or semi-liquid rock may escape. They often develop when tectonic plates collide or diverge, although volcanic hotspots may also cause them to form in the midst of plates.
When lava and gas are expelled from a volcano, often explosively, this is known as an eruption. A "glowing avalanche," which occurs when recently erupted lava slides down the flanks of a volcano, is the most hazardous form of eruption. They are capable of rapid movement and may reach temperatures of 1,200 degrees Fahrenheit. Other dangers include lahars and ash fall (mud or debris flows). Food shortages and population dislocation are frequent effects of volcanoes.

Explanation:
The Punnett Square would look like this (T - tall, t - short):
| T | T |
t | Tt | Tt |
t | Tt | Tt |
All offspring carry the short gene, but the tall gene is dominant, so the plants are tall with the possibility of having short offspring of their own.
Recessive: Short

• What type(s) of carbon-based molecules (organic compounds) are the source for most of the energy in the foods you eat..
•Where is energy stored in these molecules
Answer:
Carbohydrates
The answer to this question is yes and no. All of the carbon- based molecules in food store chemical energy in their bonds. Carbohydrates and lipids are the most important energy sources in foods you eat. However, this energy is only usable after these molecules are broken down by a series of chemical reactions.
The carbon-based molecules (organic compounds) that are the source of most energy in the food you eat are carbohydrates. Carbohydrates store energy in their chemical bonds.
What are carbohydrates?Carbohydrates are one of the three primary nutrients included in foods and beverages, along with proteins and fats. Glucose is created by your body's breakdown of carbs.
The bonds in every carbon-based food molecule store chemical energy. The two main types of energy found in food are carbohydrates and fat. But only after a sequence of chemical events has broken down these molecules can this energy be put to use.
Therefore, Carbohydrates are the carbon-based molecules (organic substances) that make up the majority of the energy in the food you eat. Energy is stored in the chemical bonds of carbohydrates.
