Read through this series of events that lead to cellular respiration, or the production of energy in your body. Put these events in the correct order by numbering them from 1 to 5 in the blank boxes next to the events.
You eat a hamburger and breath oxygen
Oxygen and glucose combine to form carbon dioxide, water, and ATP.
Energy is used by cells in your body to function and grow; you exhale carbon dioxide.
Oxygen goes immediately from your lungs to blood vessels to cells.
Food molecules in the hamburger are broken down into glucose in the digestive system.
Answer:
You eat a hamburger and breath oxygen
Oxygen goes immediately from your lungs to blood vessels to cells.
Food molecules in the hamburger are broken down into glucose in the digestive system.
Oxygen and glucose combine to form carbon dioxide, water, and ATP.
Energy is used by cells in your body to function and grow; you exhale carbon dioxide.
The digestive and respiratory systems work together to provide oxygen and organic compounds to the body, which, through cellular respiration, produce ATP and water and release CO₂. The order is A, D, E, B, C.
Every function in the organism needs the energy to occur.
Different systems work together and are equilibrated to achieve correct functioning.
For instance, the digestive and respiratory systems work together to provide oxygen and organic compounds that are used to produce energy through cellular respiration.
Cellular Respiration processCellular respiration is a process through which cells produce energy by degrading organic compounds.Aerobic cellular respiration depends on the presence of free oxygen, and occurs in the mitochondria.It is a series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules. GlycolisisRespiration begins with the process of glycolysis, which occurs in the cytoplasm.It does not need oxygen to occur. Glycolysis is the process through which the cell partially decomposes glucose and turns it into pyruvate.
Pyruvate enters the mitochondria matrix and turns into Acetyl CoA.
Krebs CycleIt takes place in the mitochondria matrixAcetyl CoA enters the Krebs cycle through which CO₂ is released and ATP, NADH, and FADH₂ are produced.Oxidative phosphorylationThe process of oxidative phosphorylation is constituted by the electron transporter chain + chemiosmosis.It occurs in the internal mitochondrial membrane. It uses electrons from NADH and FADH₂ to produce ATP and water molecules.
The correct order of events is as follows,
A) You eat a hamburger and breath oxygen
D) Oxygen goes immediately from your lungs to blood vessels to cells.
E) Food molecules in the hamburger are broken down into glucose in the digestive system.
B) Oxygen and glucose combine to form carbon dioxide, water, and ATP.
C) Energy is used by cells in your body to function and grow; you exhale carbon dioxide.

Artificial Selection is another name for _____________.
Answer:
selective breeding
Explanation:
Artificial selection is also known as selective breeding. Selective breeding refers to the process of breeding plants or animals selectively.
explain how mutation evolution might
occur in a population
Answer:
mutations create a new particular gene, a new allele. If that allele is passed down to the next offspring and the next, the mutation would be carried throughout the population. Some of the species in the population might not show any symptoms of a mutation or not feel the effects of it, but pass it down. If the mutation is neutral (causing no harm or no good), it may be passed down. If the mutation is beneficial to the species, and helps them survive, it may be passed down more. If the mutation is harmful, the mutation may eventually stop being passed down, and start to only appear if something happens genetically (mutation still may happen, but not because of passing down from parent to offspring).

Consider two pure-breeding lines of grapes, P1 and P2. The average diameter of P1 grapes is 1.2 cm and the variance is 0.30 cm2. The average diameter of P2 grapes is 1.6 cm and the variance is 0.56 cm2. The two pure-breeding lines are crossed to produce F1 progeny. Based on this description, which of the following statements is false?
a) VG for F1 is > 0
b) VP for P1 < VG for P2
c) VE for F1 is > 0
d) VG for P1 = 0
e) VG for P2 = 0
Answer:
a)
Explanation:
From the given information:
The avg diameters:
For P1 grapes =1.2 cm
For P2 grapes = 1.6 cm
Their vairance is also given as follows:
For P1 = 0.30 cm²
For P2 = 0.56 cm²
Recall that:
the phenotypic variance VP = genetic variance (VG) + environmental variance VE
As stated that P1 and P2 lines are pure breeding lines, which means that the diameter of the seed in F1 was around halfway between the two parents' and the difference in the F1 was close to the parents'.
This implies that, provided the parent lines exist as pure breeding;
The genetic variation would be absent, indicating that VG is zero.
∴
VP = VE and VG = 0
Now, averaging the results of two pure breeding lines, we have:
[tex]V_E = \Big (\dfrac{0.30 + 0.56}{2} \Big) \\ \\ V_E = \dfrac{0.86}{2} \\ \\ V_E = 0.43 \ cm^2[/tex]
The formula used in estimating F1 genetic variance can be expressed as:
VP = VG + VE
Recall that
VE = VP = 0.43 cm²
∴
0.43 = VG + 0.43
VG = 0.43 - 0.43
VG = 0
Thus, The statement that is false is in Option a.
VG for F1 is > 0

Three complex carbohydrates that are very important in living things are starch, cellulose, and glycogen (see below).. All three of these polysaccharides are polymers of glucose, yet they behave very differently in our bodies. We can digest starch and glycogen, but not cellulose. Examine the drawing of these three polysaccharides below. What differences can you see between these molecules that might explain why
Answer:
The functional group highlighted in pink alternates its position on the carbohydrate molecule
Explanation:
Complex carbohydrates or polysaccharides are large molecular weight molecules composed of repeating unit of simple carbohydrates which are joined together by covalent bonds known as glycosidic bonds. These glycosidic bonds are foremd between the carbon at position number 1 (known as the anomeric carbon) of one simple carbohydrate and a hydroxyl group of another simple carbohydrate.
The configuration of these linkages determines the properties and functions of the complex carbohydrates. The complex polysaccharides starch, glycogen and cellulose are all composed of glucose monomers linked together by glycosidic bonds.
In storage polysaccharides such as starch and glycogen whose function is to store the simple carbohydrate glucose for when needed by the organism, the glycosidic linkages are said to be in α-linkages, placing the functional groups (CH₂OH) all on the same side.
Even the branching points in glycogen are all in α-linkages. Humans have the enzymes to break these bonds so that starch and glycogen molecules can be metabolized by the body.
In a structural polysaccharide such as cellulose, the glycosidic linkages are β-linkages which results in alternating positions for the functional groups. Since humans do not have the enzymes responsible for the breakage of these linkages, hence, we cannot digest cellulose in our bodies.

Describe how individual cell breakdown energy rich molecules to provide energy for cell functions
Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Explanation:
Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy. This process is called 'cellular respiration'. The process is happens in all the cells in our body. Oxygen is used to oxidize food, main oxidized food is sugar(glucose).

What is the life cycle of the sun? What are the phases of its life? Birth What is it now? ________________ What will it become? ______________ What will it be called as it dies out? _______________
Answer:
Main sequence, red giant, white dwarf.
Explanation:
The life cycle of the sun is called as solar cycle and is the phase of solar development. There are about seven-stage in its life cycle. Starting with the birth of the sun that is found in the solar nebula theory took place about 4.56 billion years. The sun starts to enter the T Tauri stage, followed by the main sequence stage where the sun is currently in. After this stage that is when the sun runs out of hydrogen from its core. It will produce violent helium flashes and will shrink its size. When this happens it will reach the tip of the red giant stage. Later on, the naked core will form into a white dwarf.4. which of these substances cannot pass through cell membranes?
