Answer:
Males are XY(have one X chromosome) so, when it comes to X linked diseases, they express everything that is on that chromosome. They only need one copy. Females need 2 copies of the recessive allele in order to have the same condition.
Answer:
Details about DNA are given in the explanation section. Hope it will be helpful for you.
Explanation:
DNA, or deoxyribonucleic acid, is the hereditary element in humans and almost all other organisms. Nearly every cell in a person’s body has the same type of DNA. Most DNA is found in the cell nucleus (nuclear DNA), but a small quantity of DNA can also be found in the mitochondria (mitochondrial DNA or mtDNA).
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same type in all people.
DNA bases pair up with each other, A with T and C with G, to form units that are called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. A base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix.
A valuable feature of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases.
Answer:
The most appropriate answer would be carbon dioxide and cellular respiration.
Yeast is a single-celled eukaryotic organism which is capable of doing anaerobic (fermentation) as well as aerobic respiration.
It uses cellular respiration (whether aerobic or anaerobic) for the production of energy, that is, adenosine triphosphate (ATP).
Cellular respiration refers to the set of chemical reactions which are involved in breaking down sugar or glucose to produce ATP. The carbon dioxide is produced as a byproduct.
Thus, yeast breakdown the sugar present in apple juice to produce ATP and carbon dioxide.
This carbon dioxide is released in the form of bubbles.
Answer:
<u>Isotonic</u>
Explanation:
If the solute concentration of the cell and that of its surrounding medium are the same there will be no net flow of water in either directions. In this case, the external solution is said to be isotonic to the cell.
Both the cytoplasm concentration and the glucose in the test tube are the same.
Answer: Option A) Exocytosis
Explanation:
Unlike the other pathways mentioned, exocytosis involves the outward movement of outside the cells. This is vital in the removal of waste products generated within the cell.
Thus, exocytosis is the answer because it expels materials out of the cell, rather than deliver materials to lysosomes
