Answer:
C. Chlamydia. is the correct answer.
Explanation:
Chlamydia is a bacterial sexually transmitted disease, caused by obligate intracellular Chlamydia trachomatis.
In the life of chlamydia, there are two stages of developmental(Reticulate and elementary bodies are two forms of Chlamydia.)
The elementary body is the infectious substance, they are non replicating and have a rigid outer membrane that binds to the receptors present on the host cell and it initiates the infection and due to the rigid outer membrane there, no fusion between the phagosome and the lysosome hence oppose the intracellular killing.
Reticulate bodies are the metabolically active form of a chlamydia and non-infectious.
There are no choices, I'll assume that the Nereus in the question refers to the underwater vehicle.
Facts about the Nereus
1) It is an HROV or <span>hybrid unmanned autonomous underwater vehicle. Operated underwater but its operator is in a remote location.
2) Built and operated by WHOI or </span>Woods Hole Oceanographic Institution<span>
3) Designed to explore the deepest surveyed point of the ocean worldwide named Challenger Deep.
4) Deepest dive was at 35,768 feet of the Mariana Trench last May 2009.
5) Was lost on May 10, 2014 after it imploded due to pressure in the Kermadec Trench</span>
Answer: A) Two atoms share electrons so they can fill their outer shells
Explanation: A covalent bond is a type of bond formed by sharing equal number of electrons between two non-metal atoms so that both of them can attain a stable octet or duplet structure of noble gases.
In covalent bonding, there is no loss or gain of electrons between atoms. For example, the formation of chlorine molecule, chlorine atom has seven electrons in its outermost shell, remaining one electron to attain an octet structure of noble gases. Two chlorine atoms share one pair of electron, each chlorine atom donating one electron to form a pair so that each atom in the chlorine molecule attains an octet structure..
Well i don’t know what you could pick bc the statements aren’t here i don’t think you added them but here is the detention of meiosis // a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
hope that helps
