Answer:
Explanation:
When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.

Los procesos de respiración aerobia celular y fotosíntesis, procesos considerados indispensables para la vida en la tierra, de los que es correcto afirmar que Son de carácter antagónico, es decir el cloroplasto ejecuta reacciones anabólicas y la mitocondria catabólicas. La respiración celular sólo la realizan los seres eucariotas del reino de los vegetales. Ambos son realizados por los seres considerados eucariotas. Ambos son realizados por eucariotas pertenecientes al reino de los vegetales
Respuesta:
Las opciones correctas son: a) son de carácter antagónico, es decir el cloroplasto ejecuta reacciones anabólicas y la mitocondria catabólicas; y d) ambos son realizados por eucariotas pertenecientes al reino de los vegetales.
Explicación:
La fotosíntesis y la respiración celular son procesos de carácter antagónico porque la fotosíntesis es anabólica y la respiración celular es catabólica. La fotosíntesis consiste en la producción de moléculas complejas a partir de moléculas simples (proceso anabólico), mientras que en la respiración celular se degradan moléculas complejas y se las convierte en moléculas más simples (proceso catabólico).
Ambos procesos son realizados por los eucariotas del reino de los vegetales, pero los eucariotas del reino animal sólo realizan respiración celular, ya que no tienen cloroplastos. Esta diferencia tan importante existe porque los animales pueden moverse para conseguir comida (heterótrofos), mientras que los vegetales necesitan producir sus propios nutrientes haciendo uso de la fotosíntesis (autótrofos). Más allá de esta diversidad, todos los eucariotas realizan respiración celular para producir energía en forma de ATP.

During fertilization gametes join to form a diploid cell known as a ________
Answer:
zygotes
Explanation:
Human fertilization and development
Fertilization is the process in which haploid gametes fuse to form a diploid cell called a zygote. To ensure that each zygote has the correct number of chromosomes, only one sperm can fuse with one egg.
This diagram below illustrates which specific cellular function?
A. Transcription
B. Transformation
C. DNA replication
D. Translation
Answer:
D. Translation
Explanation:
In the diagram you see a ribosome. Proteins are made at the ribosome, so it must be a process where proteins are being made from something. That something is mRNA. mRNA is made to proteins through a process called translation.
Which of the following is true about molecules?
1. Composed of the two same atoms
2. Composed of two different atoms
3. H2O is an example of molecule
4. All of the above is true.
Answer:
4) All of the above is true.
Why?
When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element. For example, when three oxygen atoms bond together, they form a molecule of ozone (O3). If a molecule forms from atoms of two or more different elements, we call it a compound. Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element. This is because they are all made up of different types of molecules. Molecules are not only made up of different types of atoms but also different ratios. Like in the water example above, a water molecule has 2 hydrogen atoms and 1 oxygen atom. This is written as H2O.

Your science teacher has charged you and your partner with making a dichotomous key .He has given you a chart of organisms that are all fish
The given question is incomplete it lacks the main question, group of choices, and dichotomous key, however, the correct question is attached as an image:
Answer:
The correct answer is - B) body shape
Explanation:
In this given dichotomous key, one can distinguish and identify the particular fish on their characteristics feature present in the diagram. In this chart, there are 9 different types of fish that share some characteristic features such as fins, stripes, the shape of tails, and others.
The body shape of the fishes is the best characteristic to begin the choice of keys here, the shape of fishes that are skinny and long and little fat and small in comparison helps in distinguish these fishes.

Estrogen helps control the menstrual cycle and also helps childbearing.
The hormone estrogen is highly produced by ovaries, while some of the estrogen is also produced by the adrenal gland.
What do you mean by Hormone?Hormones may be defined as the chemical substances which are secreted by the endocrine glands and are transported to the target site via the bloodstream.
There are numerous functions of the hormone estrogen found in the body of a human female.
It helps in stimulating the growth of the egg follicle. It regulates the menstrual cycle. It also controls the thickness of uterine mucus secretions.
Therefore, it is well described above.
