Answer:
D: Helicase breaks hydrogen bonds in the template strand, DNA polymerase adds nitrogen bases
Explanation:
DNA replication is the process whereby DNA content is duplicated. This process of DNA replication is carried out with the aid of certain enzymes. Two of those important enzymes as stated in this question are DNA Helicase and DNA polymerase.
- DNA Helicase is the enzyme that breaks the hydrogen bonds that holds the two DNA strands in the molecule together. This separates the double-stranded DNA into two single strands.
- DNA polymerase is another enzyme that which carries out the nucleotide synthesis. DNA adds nitrogen bases to the new DNA strand based on what it reads on the DNA template

Which is true about scientific knowledge?
Answer:
Explanation:
It changes as new evidence is found.
An example is the scientific knowledge of climate change. This scientific knowledge is not agreeable across all the world scientists. However as more and more evidence is collected, over time, the understanding of climate change will change and will either refute or corroborate the earlier understanding.
Why are most stray cats short hair cats, but a variety of colors?
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.

A wildlife biologist and her team counted 150 lizards in a 25 km area. What is the population density
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

-Calculate the fluid pressure at Piston A.
-Calculate the force exerted on Piston B.
-Which principle is being applied? What does the principle state?
Show all your work!
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

2. Why must the satellite use electromagnetic
waves instead of sound waves?
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.

Answer:
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.
A cell’s digestive enzymes are enclosed in a membrane-bound organelle. How can these molecules function in the cell?
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?
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.
