Answer:
The correct answer is - Observations generate a scientific question, leading to a hypothesis, which can be tested through an experiment.
Explanation:
In any scientific knowledge development process, scientists need to follow the scientific process in a particular sequence that helps in developing and testing a hypothesis.
The sequence has:
observation: Observation requires you to pay attention to occurrences around
Forming question: on the basis of observation form a question about why that occurrence happens.
Hypothesis formation: The hypothesis is your initial prediction on why that happens.
Experiment: The experiment is being done in order to collect data and analysis so you can test your hypothesis
Explanation:
the first step in nitrogen cycle is formation of nitrates it is done by following ways.1. NITROGEN FIXATION: conversion of nitrogen into nitrates is called nitrogen fixation. it is done by three ways which include atmospheric nitrogen fixation(done by thunderstorms and lightning),biological nitrogen fixation(done by nitrogen fixing bacteria),industrial nitrogen fixation(done in industries). 2.AMMONIFICATION AND NITRIFICATION: ammonification is the breakdown of proteins and nitrogeneous wastes and nitrification is conversion of ammonia into nitrates and nitrites this procces is done by bacteria. the second step is assimilation in which the nitrates formed in the above procces are used by plants and in the third procces which is denitrification in which the nitrates are again converted into atmospheric nitrogen. I THINK IT WOULD BE HELPFULL TO YOU
Answer:
The technology that allows scientists to study the activity of many genes at once is a <u>microarray</u>.
Explanation:
A microarray is a laboratory tool which is used to detect the expressions of a thousand genes at a time and these are in the form of slides which are printed with thousands of tiny spots at a defined position, with each spot having a known DNA or a gene.

Answer:
Female egg cells grow in the ovary.
Explanation:
If we talk about female reproductive system in animals or particularly humans, ovaries are basically the sites where female egg cells are produced. These egg cells are also termed as oocytes or ova. After the production, they are transferred to fallopian tubes where the sperm is also reached and ultimately fertilization occurs. Once the egg gets fertilized, it moves towards another site called uterus. The walls of the uterus get thicker and thicker due to production of specific hormones and help in supporting the baby. You can see attached image for better understanding.
<em>Note: </em><em>The female egg cells grow in ovary but here we specifically focussed on human females. The option is true for all animals.</em>
Hope it helps!
