Answer:
Biological classification is the process by which scientists group living organisms. Organisms are classified based on how similar they are. Historically, similarity was determined by examining the physical characteristics of an organism but modern classification uses a variety of techniques including genetic analysis.

por que un globo con aire se agranda al sol y se achica en la heladera
Answer: El globo congelado se contrajo porque la energía cinética promedio de las moléculas de gas en un globo disminuye cuando la temperatura disminuye. Esto hace que las moléculas se muevan más lentamente y tengan colisiones menos frecuentes y más débiles con la pared interior del globo, lo que hace que el globo se encoja un poco.

In what organelle do the Kreb's cycle and the electron transport chain take place?
(1 point)
0. chloroplast
O mitochondria
O cytoplasm
o nucleus
Answer:
mitochondria
Explanation:
-The aerobic phases of cellular respiration in eukaryotes occur within organelles called mitochondria. These aerobic phases are the Krebs Cycle and the electron transport chain.
The Kreb's cycle and the electron transport chain take place in the MITOCHONDRIA.
Cellular respiration is an aerobic process, i.e., a metabolic process that requires oxygen (O2) by which energy from foods is used to synthesize ATP, carbon dioxide (CO2), and water (H2O). The three stages of cellular respiration are glycolysis, Kreb's cycle (also known as the citric acid cycle), and the electron transport chain.Glycolysis is an anaerobic pathway (i.e., does not require O2) and occurs in the cytoplasm.The Kreb's cycle and the electron transport chain (ETC) are both aerobic processes that occur in the intern membrane of the mitochondria.In conclusion, Kreb's cycle and the electron transport chain occur in the mitochondria.

A DNA segment is changed from AATTAG to AAATAG. What type of mutation is this and what is its effect on the genetic variation of a population?
A.
The mutation is a substitution which causes a decrease in the genetic variation of a population.
B.
The mutation is an insertion which causes a decrease in the genetic variation of a population.
C.
The mutation is an insertion which causes an increase in the genetic variation of a population.
D.
The mutation is a substitution which causes an increase in genetic variation of a population.
The mutation from AATTAG to AAATAG is a substitution which causes an increase in genetic variation of a population.
MUTATION:
Mutation refers to any change in the nucleotide sequence of DNA molecule. Mutation can be of different types depending on how it occurs. A substitution mutation is that in which one or more nucleotide base is replaced by another in the sequence. In this question, an original sequence of DNA is given as AATTAG. It was mutated to AAATAG via the replacement of 'T' with 'A'. This means that it is a substitution mutation. However, this mutation will cause an increase in the genetic variation i.e. difference in a population.Learn more at: https://brainly.com/question/21220597?referrer=searchResults

What is the function of a chloroplast? A. Gamete production B. Cellular respiration C. Fermentation D. Photosynthesis
Answer:
So i had these notes from a couple of days ago and I’d like to help u out
Explanation:
Photosynthesis
Carbon dioxide enters through the leaf which contains small pours called stomata. The carbon dioxide then enters the cells of the leaf.
Inside the cell carbon dioxide diffuses into the chloroplasts. Where photosynthesis takes place
Chloroplasts use energy from sunlight to transform carbon dioxide and water into sugar and oxygen.
The light reactions
Inside chloroplasts there are these flat membranous sacs called thylakoids.
Thylakoids are the place were light energy is converted into chemical energy in the first phase of photosynthesis the light reactions.
Photosystems
Photosystems are large complexes of proteins and chlorophyll (capture light energy)
Electron transport chain
This chain connects the two photosystems.
Electron carrier
These shuttle (transport that is mainly between 2 things going back and forth) electrons from one photosystem to another
Photosystem
One of the photosystems are used to absorb energy which then excites the electrons that then enter the electron transport chain. These electrons are replaced with electrons stripped from water creating oxygen as a byproduct.
The electrons on the chain
The energised electrons are flowing down the electron transport chain releasing energy that is used to pump hydrogen ions
Hydrogen ions
An atom or molecule that has a net electrical charge due to the loss of one loss or one gained electron.
The electrons on the chain
As the hydrogen ions get pumped out they are then absorbed into the thylakoids
In the photosystem on the right light energy excites electrons and this time the electrons are captured by an electron carrier molecule also known as NADPH
The high concentration of hydrogen ions inside the thylakoid powers ATP synthase producing ATPS the light reactions in the thylakoid have produced two products, ATP and NADPH.
Those two products then power the production of sugar in the Calvin cycle
THE CALVIN CYCLE (C3 Cycle)
The Calvin cycle takes place outside the thylakoids in the stroma (the thick fluid of the chloroplast).
At the beginning of the cycle
carbon dioxide molecules combine with molecules called rubp the resulting molecules go through a series of reactions powered by ATP and NADPH from the light reactions sugar molecules known as g3ps are produced.
G3ps
Most of the g3ps molecules are rearranged back into rubp’s that begin the calving cycle again.
The important product
Then some of the left over g3ps is the remaining g3p sugar, some g3ps are used to build glucose which can then combine into starch or even cellulose
Bits of left over g3ps are also able to break down by cellular respiration, which uses oxygen in the plants own mitochondria, this generates ATPS that can power other work of the plant.
The left overs
Excess oxygen diffuses out of the leaf through the pores while more carbon dioxide goes into the leaf pores.

A skateboarder drops in off the top of one side of the half pipe shown below. She does not push off and starts from rest. She stands straight as she skates down one side and up the other. She expected to get to the top of other side but didn’t make it. The skateboarder recalled the law of conservation of energy from science and didn’t understand why she didn’t make it to the top of the other side.
Which of the following actions would help the skater reach the top of the other side of the half pipe?
Lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
Hold a weight in order to increase her mass and cause the skateboard to move with a greater velocity down the half pipe.
Sit on the skateboard in order to lower her center of mass and increase the potential energy of the skateboard.
Push off at the bottom of the half pipe in order to replace lost energy and add kinetic energy to the skateboard.
The actions that will help the skater reach the top of the other side of the half pipe is to lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
The law of conservation of energy from science states that energy can neither be created nor destroyed but can be transformed from one form to another.
The skateboarder couldn't make it to the top of one side of the half pipe because the kinetic energy that was generated was converted to heat energy through friction.
As the heat energy is lost to the surrounding environment, the skateboard loses velocity.
Bending down by the skateboarder will provide additional energy to make up for the lost energy.
Therefore, in order for the skateboarder to reach the top of the other side of the half pipe, she has to lubricate the wheels in order to reduce frictional force that is causing her to lose velocity and bend down while skating off the side and bottom of the half pipe.
