Answer:
The number of genes partially explains how an organism has evolved and how it gained complexity.
Explanation:
The number of genes of a bacteria versus an eucaryotic organism is quite distinct and so is their complexity. A prokaryotic organism like a bacteria has a set of genes necessary to exert their basic functions and the number of genes compared to a eucaryotic cell is 3-30 times smaller, which defines a direct correlation of number of genes and complexity. However if we consider only eucaryote organisms and their complexity there is no such direct correlation between number of genes and their complexity when, for example, we compare the number of genes of humans (approximately 18000) and the number of genes of the <em>Trichomonas vaginalis, </em>an anaerobic, flagellated protozoan parasite and the causative agent of trichomoniasis. The number of genes of <em>T. vaginalis</em> is far bigger than the human cell, however the human complexity is far more advanced than the parasite organism.
Answer:
The correct answer is C. Mammals can produce milk for their offspring.
Mammals are the members of class mammalia. The word mammalia was derived from Latin word "mamma" which means "breasts" as they had a unique feature i.e. presence of mammary glands.

Answer: water and light
Explanation:
Abiotic factors are non living things that affect biotic factors for an example plants need water and sunlight to live which are abiotic factors
<h2>Sewerage & water system</h2>
Explanation:
- The purpose of municipal water delivery systems is to move consumable water from a water treatment office to private purchasers, for use as drinking water, water for cooking, water for sterile conditions, and other water use in a household situation. Water supply additionally is basic for business furthermore, industry to work in a metropolitan domain.
- A civil water supply systems can't support its clients except if there is a ceaseless stockpile of water to meet household utilization needs in the broadest sense and water requirements for auxiliary fire assurance. Water sources should be chosen cautiously to ensure that this central necessity is met.
- Hence, the right answer is "a fair and accurate evaluation of sewerage & water system"
