Answer:
Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs.
Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder.
You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.
There are three types of genetic disorders:
Single-gene disorders, where a mutation affects one gene. Sickle cell anemia is an example.
Chromosomal disorders, where chromosomes (or parts of chromosomes) are missing or changed. Chromosomes are the structures that hold our genes. Down syndrome is a chromosomal disorder.
Complex disorders, where there are mutations in two or more genes. Often your lifestyle and environment also play a role. Colon cancer is an example.

22. An astronaut on the space station tests whether gravity affects the productivity of tomato plants. What
is the independent variable in this experiment?
When conducting an experiment, the independent variable is always the one that produces or causes an effect or reaction on the dependent variable. In the exposed situation, the independent variable is gravity.
--------------------------------------
During an experiment, you need to consider all the variables involved.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified to analyze how another variable responds to it. The researcher changes the independent variable to observe its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, gravity is the independent variable, and influences the productivity of tomato plants. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. Controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.------------------------

Answer:
(Q1: B)
(Q2:B)
(Q3:C)
(Q4:D)
(Q5:B)
Explanation:
Question 1:
A consensus hears all voices in a group and goes with the common "majority rule" and B shows this in clear detail.
Question 2:
They both have different skill sets but we can remove option A because all fossils are handled the same way. We can remove D because it doesn't make sense for the question which leaves us with C and B. This makes us know that the answer is B because it makes the most sense for the question.
Question 3:
An anthropologist is someone who specializes in the study of human societies and cultures and their development and an archaeologist is someone who digs up fossils. The only answer that makes sense here is C because the archaeologist can uncover the tools and where they made marks in the rock while an anthropologist can use those to discover what civilization it was and how those tools were used.
Question 4:
In the context of this question we can decide that the only relevant answer is D because it would watch over a period of time that could show climate change while the others are just simple facts that can be uncovered about the daily life of these insects.
Question 5:
The steps that can be taken to fix coral bleaching are to reduce stressors, such as sedimentation and pollution, and limiting climate change. This is because the main things that cause the coral to become bleached are changes in the temperature and salinity of the water. By polluting the ocean we change the chemical formula of the water and therefore affect the coral and the climate change heats the ocean to temperatures that the coral can't or will not be able to withstand.

an experiment is replicable if different scientist can do the experiment and get the same results true or false
Answer:
True
Explanation:
if multiple scientist do the same thing that means they are replicating the experiment
The statement "An experiment is replicable if a different scientist can do the experiment and get the same results" is definitely true.
What is a scientific experiment?A scientific experiment may be defined as a complete set of procedures that are carried out under controlled conditions in order to determine the validity and accuracy of a hypothesis or construct a discovery.
If multiple scientists construct the same hypothesis and perform identical research and received the same results. It implies that they are just replicating the same experiment number of times.
But the only difference is that they understand different things and methodology very closely based on such outcomes. This gives each scientist a sense of special perception based on facts and evidence.
Therefore, the statement "An experiment is replicable if a different scientist can do the experiment and get the same results" is definitely true.
