Answer:
Explanation:
There are 100 division in degree celsius between 0°C - 100°
There are 180 division in degree Fahrenheit between 0°C - 100°C
There are 100 division in degree celsius equal to 180 divisions of Fahrenheit
1 division of celsius = 180 / 100 = 1.8 divisions of Fahrenheit .
1 degree of celsius = 1.8 degree of fahrenheit .
Answer:
Perception
Explanation:
When a person is given some sensory information, the receptors of sense organs sense the given information and send it to the brain which analyses and interpret it to make the required response.
Likewise, when someone is given a picture of a dog, the photoreceptors see the image and send the sensory information to the brain. The brain analyzes the sent visual information and identifies it as a dog based on previous experience.
The process of sensing the information followed by its analysis and interpretation by the brain to develop the required understanding is called perception.
Answer:
The roman numerals in blue are the labels I will write below.
Explanation:
i. lone pair of electrons on oxygen atom
ii. covalent bond between oxygen and hydrogen
iii. partial charges that are due to oxygen's high electronegativity. Oxgen will pull the pair of electrons in the covalent bond towards itself and that obtaining a partial negative charge, while hydrogen obtains a partial positive charge.
iv. hydrogen bonds between partially negative oxygen and partially positive hydrogen.
PS. EACH WATER MOLECULE CAN MAKE UP TO 4 HYDROGEN BONDS. ONE WITH EACH HYDROGEN AND TWO FOR EACH ELECTRON LONE PAIR ON OXYGEN. (refer to the middle water molecule in the diagram)
Answer: Meiosis is important because it helps to sexually reproduce offsprings with diploid number of chromosomes and enables genetic diversity in a population. Without meiosis, gametogenesis (production of new gametes) can not occur.
Explanation:
Meiosis is a type of cell division in which parents' cells undergoes division twice to produce four daughter cells each with half the number of chromosomes of the parents. In meiosis, a diploid cell undergoes division to produce a haploid cell and two haploid cells combine to form a diploid offspring. Meiosis occurs in sex cells or gametes. The crossing over of genes that occurs in meiosis allows the combination of the two parental (paternal and maternal) genes resulting in an offspring in which either of these genes is expressed
