Which of these is an important part of the scientific process?
A. Observation
B. Nationality
C. Phrenology
D. Religion
Answers
Answer:
A. Observation
Explanation:
To follow the scientific process you must first observe what phenomena you want to study, then you can make a hypothesis. The other options are not part of the scientific process.
Observation is the first step to the scientific process.
Nationality and religion can be a VARIABLE in the experiment, and phrenology is THEORY that has been tested through the scientific process but those answers are not an important part of the process itself.

A wildlife biologist and her team counted 150 lizards in a 25 km area. What is the population density
Answers
Given parameters:
Number of lizards = 150 lizards
Area of the study = 25km²
Unknown:
Population density = ?
Solution:
Population density refers to the number of organisms per area in a particular location.
Mathematically;
Population density = [tex]\frac{Total Population}{Area}[/tex]
Population density = [tex]\frac{150}{25}[/tex] = 6lizards/km²
The population density of the study area is 6lizards/km²
2. Why must the satellite use electromagnetic
waves instead of sound waves?
Answers
Answer:
Since electromagnet waves do not need a medium they can travel through space. Sound waves can't travel through space because they need a medium.
Explanation:
The satellite uses electromagnetic waves instead of sound waves these types of waves do not require any medium for the transmission of the information.
What types of electromagnetic waves are used by Satellites?The types of electromagnetic waves that are used by satellites are known as radio waves. These waves are utilized in order to carry out satellite signals with a speed of 3000,000km/sec.
Electromagnetic waves facilitate the required amount of speed and characteristics which ease the transmission of information required by the satellites. Radio waves are traveling through the vacuum of space with the fastest speed at which the information via the satellite can be transmitted. Radiowaves are also used for spacecraft communications as well.
Therefore, the satellite uses electromagnetic waves instead of sound waves these types of waves do not require any medium for the transmission of the information.

A cell’s digestive enzymes are enclosed in a membrane-bound organelle. How can these molecules function in the cell?
Answers
Answer:
A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.
Explanation:
Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily

What are three ways energy is used by the organisms?
Answers
Answer:
Organisms use energy to survive, grow, respond to stimuli, reproduce
Explanation:
Three ways energy is used by the organism are food, nutrients, and sunlight.
What are living organisms?Living organisms are those organisms that grow, adapt, and reproduce their young ones. Organisms need energy for their biological purposes. Organisms get energy from plants and other animals. This energy is used in the form of glucose.
Cellular functions require energy, which living things must obtain from food, nutrition, or sunshine. Energy is used in a cell for the transport, synthesis, and breakdown of nutrients and molecules.
Glucose and ATP are the two types of molecules that organisms primarily use for chemical energy. In the entire biological universe, both molecules are used as fuel.
Therefore, the energy is used by the organisms in three ways that are food, nutrients, and sunlight.

Why are most stray cats short hair cats, but a variety of colors?
Answers
According to the American Humane Society, roughly 95% of all cats are short hair cats (called domestic shorthair). This applies not just to strays but cats that have owners as well. So that fact alone is enough to be able to see why most strays are short hair cats.
Through my research, I'm reading that some people claim that long hair cats are more expensive and rare cats, so the owner is likely to take better care of them and keep them indoors. This further inflates the percentage of stray short hair cats out on the street. I couldn't find much about this from an official source, but instead just through forum posts.
As for the colors, I'm not entirely sure. The cat's fur color comes from its genetics. So it's possible that darker more earth-tone colors help the animal survive better compared to say a lighter color or white fur. Due to natural selection and survival of the fittest, the darker hair color cats will eventually out-number the lighter fur colors. That's my theory anyway. I couldn't find much data or studies to back that up.

C. Guanine
Explanation:
A pairs together with T, or U in RNA,
and C and G always pair together.
Answer:
The answer is C. Guanine
Explanation:
Pyrimidines always bond with purines. Since Cytosine is a pyrimidine, it must bind with a purine, which can either be Adenine or Guanine. However, Adenine has only 2 places for hydrogen bonding while Guanine has 3. Since Cytosine also has 3, it would bind to Guanine. GCAT is a useful acronym for remembering which binds to which.

Answers
Answer:
80N
Explanation:
in both sides, pressure is the alwyays the same whatever the area is..
First we calculate the pressure at piston A:
P= F÷a
given that,
#F= 20N
#a=1m^2
P= 20÷1
P= 20 Pa.
At piston B:
pressure is the same = 20Pa
Area= 4m^2
P=F/a
F= P×a
F= 20 × 4
F= 80N
