Answer:
fossils are used to tell how long they lived what did they eat how they died habitat what they eat
Explanation:
The fossils present in a rock exposure or in a core hole can be used to determine the ages of rocks very precisely. Detailed studies of many rocks from many places reveal that some fossils have a short, well-known time of existence. These useful fossils are called index fossils.
Answer:
Fossils have been used by scientists to determine the dates of rock layers (or strata) that were laid down in succession hundreds of years ago. However, the accuracy and precision of this method depend on several conditions, such as depth, lithology, thickness and abundance of the fossils in that rock.

Explanation:
CELLULAR RESPIRATION:
Cellular respiration is the process whereby living organisms obtain energy (ATP) by breaking down food molecules in their cells. All living organisms including Cheetahs perform cellular respiration by breaking down glucose to synthesize energy in form of ATP needed for their metabolic activities. Photosynthesis is performed by green plants to synthesize glucose using light energy. These glucose molecules are broken down during cellular respiration performed by animals to synthesize energy.Learn more at: https://brainly.com/question/13721588?referrer=searchResults

Explanation:
2. The common organelles present in both plant and animal cell include the nucleus, cytoplasm, cell membrane, mitochondria, ribosome, etc. The presence of these common organelles is due to the fact that that these organelles help both plants and animal cells to carry out the basic functions of life. Also, plant and animals cells are both eukaryotic cells.
3. Plant cell differ from animal cells due to some specialized functions they carry out like photosynthesis, as well as some structural differences in plant cells. Plants cells have chloroplasts which are organelles responsible for photosynthesis in plants. Plant cells also have a large central vacuole unlike animal cells which help to maintain turgidity in plants. Cellulose cell wall in plant cell also serve to maintain the rigidity and give shape to the plant as well as to protect the plant cell.

Negative pressure rooms are sometimes referred to as source isolation rooms, while positive pressure rooms are sometime called protective isolation rooms. Explain the thinking behind these names.
Answer:
Negative pressure rooms are sometimes referred to as source isolation rooms because they prevent potentially contaminated air to exit the room.
Positive pressure rooms are also known as protective isolation rooms because they prevent the entering of any pathogen in the air to the room where a patient with a compromised immune system is staying.
Explanation:
Negative pressure rooms or source isolation rooms have lower pressure than the outside. Due to this pressure difference, air can enter the place but can not leave it, trapping the pathogens. Patients with infectious conditions are in these rooms to prevent the spreading of the disease. That is why they are also called source isolation rooms. These rooms have a system that filtrates and circulates the air.
On the other hand, in positive pressure rooms, the air pressure is higher. As a result, the air, with any potential bacteria, virus, or particles, leaves the room to keep the patient safe. They are also known as protective isolation rooms because patients with a compromised immune system are there to protect them from any pathogens in the air.
Microcystis aeruginosis is a freshwater photosynthetic cyanobacterium. When temperatures increase and nutrients are readily available in its pond habitat, M. aeruginosis undergoes rapid cell division and forms an extremely large, visible mass of cells called an algal bloom. M. aeruginosis has a short life span and is decomposed by aerobic bacteria and fungi. Identify the metabolic pathway and the organism that is primarily responsible for the change in oxygen level in the pond between times I and II AND between times III and IV.
Complete question:
You will find the figure with cyanobacteria, decomposers, and oxygen concentration curves in the attached files.
Answer:
- between times I - II: cyanobacteria produce oxygen through the procees of photosynthesis.
- between times II - III and III - IV: decomposers consume oxygen through the process of respiration.
Explanation:
Cyanobacteria, also known as green-blue algae, inhabits the euphotic stratum, producing oxygen through the process of photosynthesis. Probably they produce among 20 - 30% of the global photosynthetic activity. When they die, they sink to deeper water strata.
At the time I, the cyanobacteria population experiences a fast growth, which can be seen through the positive sharp increase of the curve slope. The curve reaches a maximum point just before time II, where it begins to decrease. Cyanobacteria reproduce, and the population grows in size. The more cells there are, the more photosynthetic activity, and the higher amount of oxygen is produced. Following cyanobacteria growth, there is an increase in oxygen concentration, which is reflected by the sharp increase in the curve slope. Both curves are very similar, but they are separated on time, meaning that first cyanobacteria need to reproduce and photosynthesize to posteriorly observe a proportional increase in oxygen concentrations.
Just before time II, the cyanobacteria population stops growing, and at time II begins a sharp decrease in size, reflected in the curve slope. Living cells still produce oxygen, but as there are fewer cells, oxygen concentration also decreases. Cyanobacteria are decomposed by aerobic bacteria and fungi. These last organisms consume oxygen through the process of respiration. As cyanobacteria die and are decomposed, aerobic cells can reproduce at higher rates, increasing their population size. This also can be seen reflected in the decomposers curve, which is stable until time II where it shows a sharp positive increase in its slope. As decomposers' population increases, they consume more oxygen, which concentration decreases inversely proportional to the decomposers' increase. This can be seen in the curves: from time II to time III, the aerobic organisms curve increases and the oxygen curve decreases, so as the cyanobacteria curve.
Just before time III cyanobacteria population stabilizes and during time IV keeps equal. Oxygen concentration keeps following, from time II to IV. When cyanobacteria stabilize, before time III, decomposers population starts to decrease, but they still consume oxygen.
At which location along a river or stream would the greatest rate of erosion most likely occur?
A. at its point nearest to the ocean
B. at its steepest incline
C. at its widest point
D. at its origin
Answer:
B. at its steepest incline
Explanation:
The steepness of a body such as river or stream refers to the downward slope or gradient of the body of water.
Generally, the steepness of a body affects the rate at which other materials would flow or move around. Thus, the steeper a river or stream, the greater would be its rate of erosion.
Hence, the location along a river or stream at which the greatest rate of erosion would most likely occur is at its steepest incline.
The study of rivers is called limnology.
The correct answer to the question is B that is at its steepest incline
What is erosion?The removal of the upper layer of soil is called soil erosion.

Plants on land and in the ocean convert carbon dioxide to biomass through photosynthesis.
What do you mean by photosynthesis?Plants and other organisms use a process called photosynthesis to transform light energy into chemical energy that can later be released to power the organism's activities through cellular respiration.
A chemical reaction that occurs when sunlight is applied to algae, plants, and some bacteria. During photosynthesis, water and carbon dioxide join to frame carbs (sugars) and radiate oxygen.
In plants and green growth, which grew a lot later, photosynthesis happens in a specific intracellular organelle — the chloroplast. During daylight, chloroplasts perform photosynthesis.

How might Kangaroo population suddenly increase? How might this affect the ecosystem?
Answer:
The kangaroo population could suddenly increase if the predator of the kangaroo found something else to hunt, or started to go extinct. If this were to happen, then the prey of the kangaroo would most likely go extinct due to the sudden rise in population of the kangaroo. If there were more kangaroo, then there would be less of whatever the kangaroo ate, then the prey of whatever the kangaroo ate would suddenly increase, it goes all the way down the chain.

Which discovery supported the endosymbiotic theory?
The discovery of independent DNA (from the host) in mitochondria and chloroplasts supports the endosymbiotic theory.
The endosymbiotic theory is the theory that mitochondria and chloroplasts, two important organelles found in eukaryotic cells, originated from bacteria that were engulfed by larger cells.
What is this theory?The presence of DNA in mitochondria and chloroplasts. Mitochondria and chloroplasts have their own DNA, which is separate from the DNA in the nucleus of the cell. This suggests that they were once independent organisms.
The similarity of mitochondrial and chloroplast DNA to bacterial DNA. The DNA in mitochondria and chloroplasts is similar to the DNA of bacteria. This suggests that they share a common ancestor.
The presence of ribosomes in mitochondria and chloroplasts. Mitochondria and chloroplasts have ribosomes, which are structures that are used to make proteins. Ribosomes are also found in bacteria.

Which of these statements best describes the characteristic of water that impacts its role in moderating Earth's climate?
Answer:
Water is a fluid with a high specific heat.
Explanation:
Specific heat is defined as the amount of heat energy measured in calories, that is required to change the temperature of one gram of a substance by one degree Celsius. Water has a very high specific heat of 4.184 Joules. This means that water does not get heated up or cooled easily.
This is important for earth's climate and the organisms in it as they are not subject to sudden and frequent temperature fluctuations.
