A placebo is a fake treatment that mimics the experience of the experimental group.
true
false
Answer:
true
Explanation:
Doctors (or scientists) usually use this to make sure people aren't lying about the experience.
For example, some people might expect that if they take ibuprofen or Tylenol, they won't feel as much pain, so they might make themselves believe that they aren't feeling said pain. If you use a placebo group, you are less likely to have situations like that occur, and so your data becomes more accurate.

Answer:
Auxins are added to the agar because Auxins control the growth of plants by promoting cell division and causing elongation in plant cells.

7. Compare: Return the arrows to their tray and turn on the Displacement graph. How is the displacement
graph related to the acceleration graph?
Answer:
to know how many correspond to each tray if we divide the total cookies equally, we need to make a division of the total cookies divided by the amount of trays, that is:
567 cookies / 7 trays = 567/7
= 81
therefore, there will be 81 cookies in each tray

In the following pedigree showing the transmission of Cystic Fibrosis, an
autosomal recessive condition, what must the genotype of the indicated woman
be?
A: FF
B: Ff
C: ff
D: cannot determine
*red circle is affected female*
*blue circle is normal female*
*red square is affected male*
*blue square is normal male*
In the pedigree showing the transmission of Cystic Fibrosis, the genotype of the marked woman will be FF or Ff. Thus, options A and B are correct.
What is a pedigree?Pedigree represents the heritable phenotypic trait in the form of charts and diagrams. Cystic Fibrosis disease is inherited by the autosomal recessive alleles and is possible only if the genotype is ff.
The genotype for the woman being normal should not have recessive alleles and only can be heterozygous or purebred dominant. It is possible only if the genotype is Ff and ff.
Therefore, the genotype of the indicated woman will be Ff and ff.

____________________________________ use reduced, preformed organic molecules (usually from other organisms) as carbon sources, obtain energy from the oxidation of organic compounds, and use reduced organic compounds as their electron source.
Answer:
Heterotrophs
Explanation:
Heterotroph, in ecology, is an organism that consumes other organisms in a food chain. They acquire their energy by the controlled breakdown of preexisting organic molecules, or food.
¹All heterotrophs, use organic materials as their sole source of carbon. Heterotrophs use preformed organic compounds as their source of carbon. (Source: Brittanica)
Metabolic cycles in general—the extraction by organisms of useful ²energy and food molecules from environmental source material—can be described in terms of oxidation-reduction reactions
Heterotrophs can be organotrophs or lithotrophs. Organotrophs exploit reduced carbon compounds as electron sources, like carbohydrates, fats, and proteins from plants and animals. On the other hand, lithoheterotrophs use inorganic compounds, such as ammonium, nitrite, or sulfur, to obtain electrons.

Answer:
1. True
- Those are compounds
2. False
-They are actually polar molecules
3. True
-Acids are molecules that give away a type of subatomic particle
4. False
-While they are usually the same, it is not necessary to have equal protons and neutrons. However, the ratio of electrons to protons is always equal. An extra proton in an atom makes a new element and an extra neutron creates an isotope.
5. False
-An isotope is an atom that has gained an extra neutron.
6. True
-Oxygen is more electronegative than most of the halogen elements.
7. True
-Cellulose and starch are both polymers made from a glucose monomer.
8. True
-During DNA replication both strands that make up the double helix are used as a template that new strands copy.
9. True?
- I think the question is referring to a codon/nucleotide triplet, because each base cant specify a single amino acid and nucleotide triplets are made up of three nucleotide bases so id say true.
10. True
-Side chain groups vary in size, shape, charge, hydrophobicity, and reactivity, which makes them unique.

What is the relationship between ribosomes and rough endoplasmic reticulum (ER)?
Rough ER produces the polypeptide chains that ribosomes need to make protein.
Rough ER is the subunit of ribosomes that makes proteins
Ribosomes attached to rough ER make proteins that the rough ER then transports around the cell
Ribosomes transport proteins made by rough ER to the Golgi apparatus.
Answer:
Ribosomes attached to rough ER make proteins that the rough ER then transports around the cell
Explanation:
Trust me i got you
Ribosomes attached to rough ER make protein that the rough ER then transports around the cell.
What is rough Endoplasmic reticulum?Rough endoplasmic reticulum (RER), series of associated leveled sacs, part of a nonstop film organelle inside the cytoplasm of eukaryotic cells, that assumes a focal part in the blend of proteins. The unpleasant endoplasmic reticulum (RER) is so named for the presence of its external surface, which is studded with protein-orchestrating particles known as ribosomes.
This element separates it hastily and practically from the other significant sort of endoplasmic reticulum (emergency room), the smooth endoplasmic reticulum (SER), which needs ribosomes and is associated with the union and stockpiling of lipids. RER happens in both creature and plant cells.

how does the liver help in maintaining homeostasis
Answer:
The liver plays a major role in blood glucose homeostasis by maintaining a balance between the uptake and storage of glucose via glycogenolysis and gluconeogenesis. The liver is the primary organ for glucose metabolism.
Glycogenolysis: Glycogenolysis is the biochemical pathway in which glycogen breaks down into glucose-1-phosphate and glycogen.
Gluconeogenesis: Gluconeogenesis is the synthesis of glucose from non-sugar precursors, such as lactate, pyruvate, and the carbon skeleton of glucogenic amino acids.
