Answer:
By providing an example using one organ for each of the four levels of complexity, we have the following:First level organ: Skin; this is because it takes up a few cells. Second level organ: Windpipes; this is because they have more complex shapes with multiple cells. Third level organ: Stomach; this is because the stomach has to act on demand instead of a flow. Fourth level organ; Heart. The reason it is difficult to make level four organs in a lab is that it has a complicated architecture with several cells, blood vessels and tiny capillaries included. So far, scientists are yet to fully develop solutions for the level four organs and hence, difficult to create in a lab.

Its
Haploid#2
Apoptosis#3
These processes occur in one region that's
nucleus#4
Parthenogenesis#5
n turns 2n
So DiploidDna is found coiled up into chromosomes within what cellular structure?.
Answer:
Your answer is the nucleus!
Explanation:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. DNA and histone proteins are packaged into structures called chromosomes.

Will give brainliest!!!!!! pls explain the student decides that measuring the amount of co2 produced will determine the total rate of both aerobic and anaerobic respiration. explain why she is correct. explain how the student could measure only the rate of anaerobic respiration.
The student could measure only the rate of anaerobic respiration by measuring the carbondioxide gas concentration.
How to measure the rate of anaerobic respiration?In the absence of oxygen, yeasts convert glucose into ethanol and carbon dioxide. This rate of carbon dioxide is used to measure of the overall rate of anaerobic respiration.
So we can conclude that the student could measure only the rate of anaerobic respiration by measuring the carbondioxide gas concentration.

Answer:
Scientists and researchers need to have a "universal language", so they can communicate with others around the world. They use scientific names that normally have Latin origins.
The reason we use common names is so people don't get confused. Normal people won't go around saying they need to walk their canis lupus familiaris. They'd say they need to walk their dog.

How to determine the chemical reaction of cellular respiration?
Answer:
C6 H12 O6+6O2-----6CO2+6H2O+ ATP
Chemical reactions of cellular respiration may be determined by where the respiration process undergoes. This is because cellular respiration may be of two types aerobic (in mitochondria), and anaerobic (in yeast and muscle cells).
What do you mean by Cellular respiration?Cellular respiration may be defined as the strategy by which living organisms incorporate oxygen with glucose molecules, and discard as waste products, carbon dioxide, and water, apart from energy.
The general chemical reaction of the cellular respiration may be determined as :
[tex]C_6H_1_2O_6 +[/tex][tex]0_2[/tex] → [tex]CO_2 + H_2O +[/tex] ATP. (Aerobic cellular respiration).
Glucose → Pyruvate → Lactate + ATP (Anaerobic cellular respiration).
Therefore, chemical reactions of cellular respiration may be determined by where the respiration process undergoes.

Answer:
The answer would-be producers. The fact that there are primary consumers today, you would know that producers make up the bigger population. If it were smaller, the primary consumers would have eaten them all up and eventually would die out because they would have no more food source. This would be bad for all higher-level consumers.

Without the greenhouse effect, temper on Earth would (F) be too cool or too hot. G) become constant. (H) increase sharply. (I) vary too much.
Answer: (F): Be too cool or too hot.
Explanation: The Greenhouse Effect on Earth is a process of when gases in the atmosphere capture the heat produced by the Sun. Without the Greenhouse Effect, the heat reflected by Earth's surface would be lost in space. The temperature on Earth would drop drastically low and this could lead to oceans/lakes freezing over and some living organisms to die out. This would make most life incapable of living on Earth.

If the following events are arranged in the order in which they occur for an animal hiding and holding still in response to seeing a predator, which is the fourth event in the series?.
Animal hiding-holding still response follows the reflex arc sequence. The fourth event in the series is option B) signaling by efferent PNS neurons.
When the animal receives the stimuli, it responds to them. In the case of hiding-holding still response, the animal might freeze due to motor inhibition that reduces excitatory signals.
The reception and reaction to stimuli follows the reflex arc sequence.
What is reflex arc?The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts.
