All organisms come from pre-existing cells that divide.
What is Microscope?Microscope: a device that magnifies small objects, giving the user a close-up view of minuscule structures at a scale suitable for observation and analysis.
Even though optical microscopes are the focus of this article, an image can also be magnified by a variety of different wave types, such as acoustic, X-ray, or electron beams, and is then captured using direct or digital imaging, or a combination of these techniques.
The magnifying power of a microscope is a dimensionless ratio that expresses how often the thing under examination seems to be magnified.
Therefore, All organisms come from pre-existing cells that divide.

Where does the external respiration take place in pets?
Answer:
In mammals (like cat and dog pets), external respiration takes place by the exchange of gases in the alveoli of the lungs
Explanation:
External respiration refers to the process of exchange of gases, i.e., oxygen (O2) and carbon dioxide (CO2), with the environment. In mammals like humans, dogs and cats, external respiration occurs in the millions of alveoli in the lungs and the capillaries that are located in the walls of the alveoli. This process (gas exchange) happens due to simple diffusion. The O2 is taken from the environment (by inhalation) and travels from the alveoli to the blood in the capillaries that surround the alveoli, while and CO2 diffuses from the blood capillaries to the alveoli (where this gas is exhaled).

How are photosynthesis and cellular respiration related?
A. The products of photosynthesis are the reactants of cellular
respiration
B. Cellular respiration is the process animals use to produce glucose,
while photosynthesis is the process plants use to produce
glucose.
C. Photosynthesis produces water molecules, while cellular
respiration splits water molecules apart.
D. Cellular respiration provides the energy for photosynthesis.
Answer:
I would say your answer for this question would be Option D: Cellular respiration provides the energy for photosynthesis.
Explanation:
Photosynthesis is the process by which plants use the energy from sunlight, carbon dioxide, and water and convert them into food, and Cellular resipration is the process by which organisms use oxygen to break down glucose and convert it to usable energy. That means that Option B can be crossed out, along with Option C. In Option A, the products of photosynthesis are not the reactants of cellular respiration, but rather the user of the energy that Cellular respiration provides. That means you can cross out Option A, and now you are left with Option D as your answer.
Answer:
A. The products of photosynthesis are the reactans of cellular respiration

Water has a unique property. Like most liquids, it becomes denser as it cools, but at 4°C it reaches maximum density. Solid ice is less dense than liquid water, which is why ice floats. How would this property protect aquatic life in a lake?
A. The lake would not freeze solid.
B. Predators would be kept out of the lake.
C. Dissolved oxygen would remain in the lake.
D. Heat would be conducted away from the lake.
Answer:
A
Explanation:
It's A
Due to this unique property of water, the lake would not freeze solid.
What is anomalous expansion of water?The anomalous expansion of water is an abnormal property of water in which it expands instead of contracting when the temperature goes from 4 degree Celsius to 0 degree Celsius and it becomes less dense.
Due to this property of water, the aquatic life is protected deep in water in colder region so we can conclude that due to this unique property of water, the lake would not freeze solid.

What is another term for the responding variable?
O primary variable
dependent variable
independent variable
uncontrolled variable
The answer is DEPENDENT VARIABLE
-edgy 2021
Answer:
B. Dependent variable.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
Hence, an experiment is used by scientists or psychologists to illustrate how a change in variable affects behavior.
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In an experiment, there are two (2) main types of variables and these are;
I. Independent variable: this is the variable that is being manipulated or alters and as such it is the cause of a behavior. This variable stands alone.
II. Dependent variable: this variable is the direct effect of the actions of the researcher in an experiment.
Basically, the dependent variable is the variable that is being measured and tested by an experimentalist.
Hence, dependent variable is another term for the responding variable because it responds to an action.
The granite boulders in Rocky Mountain National Park are a favored place among talented climbers who specialize in the art of bouldering, or climbing harder (but shorter) routes without tying into a rope. Climbers have taken to (illegally) stashing foam crash pads underneath the boulders but marmots and other rodents chew up the pads and the litter is spread by the wind. Why would the park be overused in this manner
Answer:
Follows are the solution to this question:
Explanation:
The National Park for Rocky Mountain is among the nation's best popular national parks. Rich fauna wandering the valley and also some derisive recreational sports on the planet including its majestic peaks throughout every way is no surprise that each year upwards of 3.5 million people flocks to this park. Throughout this issue, the park would be overplayed as described, since the marginal private expense of using the parks is less than those of using the park at a marginal cost.

Scientists can learn all of the following by studying fossils EXCEPT:
Question 2 options:
How life forms have changed over time
How the environment has changed over time
How the surrounding rock layers have changed over time
How the Erath's surface has changed over time
Answer: How the surrounding rock layers have changed over time
Explanation:
I’m taking a minion quiz in science class and I submitted it and we’ll that’s the correct answer
The changes in surrounding rock layers over time cannot be studied by fossils. So the correct option is C.
What are the uses of fossils?We can learn a lot about the Earth's history of life thanks to fossils. They can help us understand the origins of life and humanity, the evolution of the planet and its environment across time, and the once-connected nature of the continents that are now widely separated.
Important evidence for evolutionary and the environmental adaptability of plants and animals may be found in fossils. Fossil evidence shows how organisms developed and how a "tree of life" may be used to illustrate this process, demonstrating the interconnectedness of all species.
Rocks can also be dated using fossils. Geologists may use fossils to study geological history because different types of fossils appear in rocks of various ages as a result of evolution. Fossils are one of the most crucial instruments for age correlation in geology.
Ammonites, for instance, are great reference fossils for stratigraphy because they may be used to compare the relative ages of two or more strata, or layers of rock, that are located in various locations across the same nation or elsewhere in the world.
Therefore, the correct option is C.

Why is absolute dating more accurate than relative dating?
Answer:
Absolute dating is a technique that uses radioactive minerals present in rocks and fossils while relative dating compare the sample in terms of age difference. However, absolute dating is more accurate because it uses half-life of an element and provides dates in years.
