Biotechnology

Biotechnology is the use of living systems and organisms to develop or make products that improve our lives and the health of our planet. The wide concept of "biotech" or "biotechnology" involves an extensive variety of procedures for modifying living organisms according to human purposes. For example, the domestication of animals and cultivation of plants, improving these through breeding programs which uses artificial selection and hybridization. For many years now, it has been used in many fields like agriculture, food production and medicine.

Steroid hormones exert their action by ________. A. entering the nucleus of a cell and initiating or altering the expression of

Blizzard [7]

Answer:

The correct option is A. Steroid hormones exert their action by entering the nucleus of a cell and initiating or altering the expression of a gene.

Explanation:

Steroid hormones are derived from cholesterol and regulate multiple biological processes. All steroid hormones exert their action by crossing the plasma membrane and by binding with their respective intracellular receptors. They stimulate cell growth in a very different way, their lipophilic nature gives them the ability to cross lipid barriers, so, without the need for extracellular signals, these hormones can easily enter the cell, cross the cytoplasm and reach the nucleus. There they bind to specific receptors that are associated with DNA promoter regions, modifying their structure and promoting the expression of the genes under their control.

Organism in which the embryonic blastopore becomes its anus

Anika [276]

Organism in which the embryonic blastopore becomes its anus Deuterostome

Explanation:

The term Deuterostome refers to second mouth. The first opening which is called blastpore becomes its anus in deuterostomes. In protostomes, this first opening will be the mouth. The other name given to these Deuterostomes enterocoelomates. It is the enterocoely from which the coelom of Deuterostom starts emerging and growing.

Chordata, Echinodermata, Hemichordata are the classes of deuterostomes:. The zygote is the one that gets developed first in protostomes and deuterostomes.Radial cleavage occurs in deuterostom in which the division of cells lies either in parallel direction or in perpendicular direction with respect to the polar axis.

Bacteria that may form endospores include A. E. coli.B. Pseudomonas and Micrococcus.C. Clostridium and Bacillus.D. Enterococcus

Degger [83]

Answer:

C. Clostridium and Bacillus.

Explanation:

Bacillus and Clostridium are the gram-positive bacteria and form endospores. Endospores are the resistant dormant structures formed by some gram-positive bacteria.

These bacteria form the endospores within their vegetative cells. The endospores are highly resistant to environmental stress conditions and make these bacterial genera the dangerous pathogens.
