how would you check that the destarching had been effective
Answer:
Test a leaf or two for the presence of starch in order to determine whether the plant is completely destarched. If a positive result is obtained - leaves turn blue-black, the plant should be left under in the cupboard or under the coverd bell jar for longer, until a negative result- no colour change - is obtained.
B. How does its genotype and phenotype
differ from the non-circled offspring?
Someone answer me please
Answer:
Due to mutation.
Explanation:
The genotype and phenotype of circled offspring is different from the non-circled offspring because it has different genetic makeup, that is responsible for its different color. The change in the circled offspring's genotype was caused by a mutation. Mutation is a change that occurs in the DNA sequence, or genetic makeup of an organism due to mistakes when the DNA is copied or environmental factors such as UV light and smoke etc.

if all cells in an organism have the same DNA, the same genes why are there so many different types of cells in the human body for example there are nerve cells and skin cells and muscle cells
Answer:
The cell (from Latin cella, meaning "small room"[1]) is the basic structural, functional, and biological unit of all known organisms. Cells are the smallest units of life, and hence are often referred to as the "building blocks of life". The study of cells is called cell biology, cellular biology, or cytology.Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.[2] Most plant and animal cells are only visible under a light microscope, with dimensions between 1 and 100 micrometres.[3] Electron microscopy gives a much higher resolution showing greatly detailed cell structure. Organisms can be classified as unicellular (consisting of a single cell such as bacteria) or multicellular (including plants and animals).[4] Most unicellular organisms are classed as microorganisms.
The number of cells in plants and animals varies from species to species; it has been estimated that humans contain somewhere around 40 trillion (4×1013) cells.[a][5] The human brain accounts for around 80 billion of these cells.[6]
Cells were discovered by Robert Hooke in 1665, who named them for their resemblance to cells inhabited by Christian monks in a monastery.[7][8] Cell theory, first developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that cells are the fundamental unit of structure and function in all living organisms, and that all cells come from pre-existing cells.[9] Cells emerged on Earth at least 3.5 billion years ago.[10][11][12]

Answer:
Asthenosphere
Explanation:
Answer:
Below the lithosphere within the upper portion of the mantle is a plastic layer of rock called the asthenosphere. According to the theory of plate tectonics, the plates are driven by convection cells located within the plastic asthenosphere.

What types of food molecules make up chicken? (Carbs, Proteins, and/or Fats?)
no links!!
but its fats right??
Answer:
Fats
Explanation:
Chicken contains many different amino acids with different R-groups. In particular, chicken contains a large number of Tryptophan amino acids, which are amino acids that contain the side chain known as “indole”.
The type of food molecules that make up chicken is Proteins. It generally contains about 20% of proteins.
What do you mean by Food molecules?Food molecules are those which give energy to living organisms and contain chemicals that are required for the growth and repair of cells and their functions in the body of living organisms.
Proteins are the polymers of amino acids, which are linked via peptide bonds. The side chains of amino acids are varied from one to another. These side chains provide stability to the amino acid sequence. Mostly, the side chain of tryptophan and arginine gives the makeup to the food molecules of chicken.
Therefore, the type of food molecules that make up chicken is Proteins.

In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. What percentage of offspring are expected to be chestnut?
Answer:
This question is incomplete, the complete question is as follows:
- In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. A homzygous black horse crosses with a chestnut horse.
What percentage of offspring are expected to be chestnut?
The answer is 0%
Explanation:
This question involves a gene coding for color in horses. The allele for black coloring (B) is dominant over the allele for chestnut coloring (b) is recessive.
According to this question, if a homzygous black horse (BB) crosses with a chestnut horse (bb), the following gamete will be produced by each parent;
BB - B only
bb - b only
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
Bb, Bb, Bb, Bb
All of these offsprings are phenotypically black colored although heterozygous in genotype. Hence, 0% of offspring are expected to be chestnut.
Answer:
