Which one is for which
mr Goodwill [35]

Answer:

Claim: A tissue is made up of many similar cells that are connected and organised.

Evidence: In cardiac muscle tissue, group of cardiomyocytes are joined in the same direction.

Claim: Cells in a tissue work together to allow the tissue to carry out its function.

Evidence: In cardiac muscle tissue, group of cardiomyocytes expand and contract at the same time.

Explanation:

Cells are the building blocks of life, and a group of specialized cells form a tissue, which has a specific function.

In human heart, the cardiac muscle tissue is a specialized type of striated muscle tissue formed from cardiomyocytes. Their fibers are branched, have a single nucleus and are joined together by intercalated discs. This tissue contracts and releases involuntarily and helps the heart to pump blood throughout the body. Cardiac muscle cells (cardiomyocytes) are the muscle cells which form the cardiac muscle tissue. They are responsible for the rhythmic beating of the heart by expanding and contracting at the same time.

members of the gram-negative genera aquifex and hydrogenobacter are hydrogen-oxidizing bacteria. an example of their metabolism
melomori [17]

Hydrogen-oxidizing bacteria are the members of gram-negative bacteria, metabolism involves using hydrogen as an electron source and oxygen as a terminal electron acceptor, hence forming water.

Gram-negative genera Aquifex and hydrogenobacter stand for "water-maker"  to indicate hydrogen oxidation and terminal electron transfer to oxygen. They are chemoautotrophs, that share the ability to oxidize H₂ and fix CO₂ to provide energy and synthesize cellular material. Applicatated for resource recovery and pollution removal.

They are known to grow at the highest temperature and grow usually at neutral or slightly acidic pH. These microorganisms use CO₂ assimilation pathways. They are metabolically versatile chemolithoautotrophs, using reductive tricarboxylic acid (rTCA) cycle.

2. The mass of the nucleus is closest to A. 99% of that in the entire atom B. 1% of that in the atom C. 10–5 of that in the atom
Tanzania [10]

Answer: Option A) 99% of that in the entire atom

Explanation:

An atom consists of three subatomic particles named protons, neutrons and electrons. The protons and neutrons are found in the nucleus of the atom, while the mass of electrons is 1/1840 (negligible).

Thus, the mass of protons and neutrons in the nucleus makes 99% of the entire atom
