Answer:
B. an external force
Explanation:
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
Hence, a secured object in an orbiting spacecraft remains at rest unless acted upon by an external force.

In an experiment, Dr.Travis examined the effects of calcium intake on osteoporosis, a condition that causes an increased risk of bone fractures. The amount of calcium ____ variable. The risk of bone fractures _________.
1. A reliable
An independent
A dependent
2. Can be changed by the participants
Can be changed by the researcher
Could change with calcium intake
Answer:
Part 1. The amount of calcium is independent variable.
Explanation:
An independent variable is a variable in an experiment which is changed to see its effects on dependent variable.
In this experiment, to know about the causes of osteoporosis, the Ca level in blood or calcium intake in changed.
So the concentration of calcium will be independent variable.
Part 2.
The risk of bone fractures is could be changed with calcium.
Explanation:
In this experiment osteoporosis or risk of bone fracture is dependent variable.
Dependent variable are results of experiment which can be changed by independent variable.
As in experiment, Calcium concentration is independent variable.
So the risk of osteoporosis depends can change with calcium.

Using this information and what you learned about mechanisms of gene expression, why do cats have such fur pigmentation
Answer:
Explanation:
Gene expression is when information from a gene is used to product a gene product, this product enables to produce protein as the end product.
Phenotype which is the physical expression of the genetic make up gives the gene expression.
Cat having a fur pigmentation indicates the presence of a functional protein that has fur i.e the genetic make up of the cat has fur which give rise to the phenotypic expression.

You are examining a substance found at a crime scene. Using a chemical test, you are able to determine that glycogen is present
in the substance. What does this mean for your investigation?
Select one:
O a. The substance is from an animal source.
O b. The substance is the poison ricin.
O c. The substance is from a plant source.
O d. The substance is a lipid.
Answer:
a. The substance is from an animal source.
Explanation:
Glycogen is a carbohydrate polymer in which animals store their excess glucose as. When animals digest their ingested food, it gets broken down into GLUCOSE. This glucose, when in excess, gets stored as GLYCOGEN.
According to this question, a substance found at a crime scene is being examined using chemical tests. The test revealed that glycogen is present in the substance. This can mean that the substance is from an ANIMAL source because GLYCOGEN is only present in animals.
Answer:
a. The substance is from an animal source.
Explanation:
I, myself, took the exam, but also glycogen is found in animals cells. It is a branch of glucose that is usually stored in liver and the skeletal muscle.
