How are chromosomes arranged in a karyotype?
Answers
Answer: A karyotype test examines these dividing cells. The pairs of chromosomes are arranged by their size and appearance.
Explanation:
In a karyotype, the arrangement of chromosomes is generally done in the order of size, that is, from largest to smallest.
What is a karyotype?It is the number and appearance of chromosomes. It comprises the length of the chromosomes, the banding pattern, and the position of centromere.
In a human karyotype, the body chromosomes or autosomes are usually aligned in approximate order of size from largest to smallest, that is, from chromosome 1 to chromosome 22.
However, the chromosome 21 is shorter in comparison to chromosome 22. The arms of the chromosomes protruding from either end of the centromere may be classified as long or short, based upon their relative lengths.
The long arm is abbreviated as q and the short arm as p. Each arm is subdivided further and is designated by a number. The locations on chromosomes can be illustrated by using the naming system.
Thus, in a karyotype, chromosomes are arranged on the basis of their size, that is, from largest to smallest.

[tex]\boxed {\boxed {\sf The \ sun }}[/tex]
Explanation:
Photosynthesis is a special process that certain organisms (plants, algae, and some bacteria) undergo to create "food".
This turns light energy, carbon dioxide, and water into glucose and oxygen. The glucose becomes the food for the organism, because it is turned into ATP during cellular respiration. The ATP is energy that fuels the processes, like growth, repair, and transport.
This process occurs because of the sun. It provides the light energy needed for the reaction. Organelles inside of the cells, called chloroplasts, contain a pigment (chlorophyll) that captures this energy.

What energy carriers can enter the electron transport chain in mitochondria to generate ATP?
Answers
Answer: The electron transport chain consists of complexes which are the proton pump for the hydrogen ions across the mitochondrial membrane which allows the synthesis of the ATP (energy currency).
Explanation:
The electron transport chain occurs in the mitochondria. ATP synthase present in the inner mitochondrial membrane is a carrier of electron. FADH2 AND NADH two molecules supply high energy electrons from the citric acid cycle from the electron transport chain at complex I (NADH coenzyme Q reductase) and II (succinate dehydrogenase)respectively.

Explanation:
Normal cells responds to contact inhibition. When they come into contact with other cells, they stop moving and dividing. This keeps the cell contained within their own tissues. How did the mutated (cancer) cells show the evidence that they do not respond to contact inhibition?
Answers
Answer:
Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.
Explanation:
The mutated (cancer) cells show the evidence that they do not respond to contact inhibition because there is no stopping of division of the cells.
Normal cells VS mutant cellsNormal cells show response to contact inhibition when they come into contact with other cells, so they stop moving and dividing.
While on the other hand, The mutated (cancer) cells show the evidence that they do not respond to contact inhibition because there is no stopping of division of the cells so we can conclude that no stopping of division occurs which is the evidence that the cancer cells show no response to contact inhibition.

OW
Answers
Explanation:
Given
mass of coolie = 40 kg
Mass of salt = 20 kg
Total mass (m) = 40 + 20 = 60 kg
Displacement (h) = 20*20 = 400 CM = 4 m
Work done (w) = ?
Power (P) = ?
We know we have the formula
work done =force × displacement
or work done = m * g * h
work done = 60×10×4
work done = 2400 joules
Similarly
power = work/time
power = MGH/time
power=60×10×4/120
power=2400/120
power= 20watt

Answers
two long polynucleotide chains
A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together
Molecules of DNA are composed of long chains of nucleotides.
What are nucleotides?Nucleotides are the building blocks of DNA and RNA adenine (A), thymine (T), guanosine (G), and Cytosine (C. In RNA, uracil (U) is present instead of thymine.
The pentose sugar is the ribose sugar in RNA and deoxyribose sugar in DNA. In deoxyribose sugar, oxygen is absent from the 3' carbon.
Phosphate groups are attached through the 5-C of pentose sugar by an ester bond. One polynucleotide chain is formed when the phosphate of one nucleotide forms a phosphodiester bond with the sugar of another nucleotide.
A double-stranded structure is formed by base pairing between nucleotides. The adenine binds to thymine by two hydrogen bonds and guanine binds to cytosine by three hydrogen bonds.
Therefore the molecules of DNA are composed of long chains of nucleotides.
