Correct Answer: Eukaryotic cells are found in plants, animals and unicellular organisms The three main part of Eukaryotic cells are 1 Plasma membrane or membrane-bound organelles which carries out the cell functions 2 Nucleus which contains the cell's DNA (and) 3 Cytoplasm which is a jelly like fluid interior of the cell
Correct Answer: Proteins
Explanation:
Here the Nitrogenous Food is Proteins.
Nitrogenous Food ::
The animal body is more than a machine. It requires fuel to enable it not only to work but also to live, even without working. A part of the food eaten must go to maintain the body
Nitrogenous food compounds are sometimes classed together under the name of proteins. These may be divided into proteids, gelatinoids, and extractives.
Correct Answer: Deoxyribose
Explanation:
DNA - Deoxyribonucleic acid is a type of nucleic acid. The sugar contained in it is called Deoxyribose.
Correct Answer: Mitochondria
Explanation:
Mitochondria are present in both plant and animal cells.
Correct Answer: The auditory tube drains into the nasopharynx
Correct Answer: FALSE
Explanation:
Hemopoiesis begins in the red bone marrow, with hemopoietic stem cells that differentiate into myeloid and lymphoid lineages.
Myeloid stem cells give rise to all the other formed elements, including the erythrocytes; megakaryocytes that produce platelets; and a myeloblast lineage that gives rise to monocytes and three forms of granular leukocytes: neutrophils, eosinophils, and basophils.
Correct Answer: When there is no selective pressure
Explanation:
Genetic drift or allelic drift is the change in the relative frequency in which a gene variant (allele) occurs in a population due to random sampling and chance.
When is genetic drift a major factor in evolution is
* When there is low gene flow.
* When there is no selective pressure.
* When there is a bottleneck.
Correct Answer: TRUE
Explanation:
True. Hormones are chemicals secreted and regulated by the endocrine system.
Correct Answer: Pulmonary abscess
Correct Answer: Glycogen
Explanation:
Glycogen is the storage form of glucose in animals and humans which is analogous to the starch in plants. Glycogen is synthesized and stored mainly in the liver and the muscles.
