Enzymes speed up chemical reactions. Which statement correctly identifies the function of the enzymes involved in DNA replication?
A: Helicase adds hydrogen bonds to the template strand DNA polymerase breaks nitrogen bases
B: Helicase adds nitrogen bases to the template strand, DNA polymerase breaks hydrogen bonds
I
C : Helicase breaks nitrogen bases in the template strand. DNA polymerase adds hydrogen bonds
D : Helicase breaks hydrogen bonds in the template strand DNA polymerase adds nitrogen bases
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
People’s choices can have a positive or negative effect on their health. Describe one positive choice and one negative health choice a person could make. Be sure to explain how each could impact an individual’s health and, if applicable, the health of others.
People nowadays try to live a healthier lifestyle. The positive and negative choices depends on some aspects. For instance, a person with a normal weight or thin can be unhealthy . Health also includes the good amount of nutrition and exercise not only the weight. A good choice a person can make is exercise more and intake good amounts of nutrition. A bad choice is not exercising and not having adequate intake of nutrition. Some people tend to lose weight by quiting some nutrients which will have a bad effect on their health since all the nutrients are important for the body and avoiding some nutrients can cause deficiency. The best thing to do is diet on calories, a type of diet from which you can eat anything(all types of food including vegetables and fruits ) but measure your calorie intake , with this a person has a higher chance of losing weight and being healthy. Exercise too is an essential factor needed for a healthy lifestyle. If a person has a lifestyle which they need to move alot(jobs including sports etc) then you can say its enough but if not a person must do exercise at least twice or more a week for better health. Quitting smoking and drugs of course has a good effect.
someone answer these 2 for me
Answer:
F=dominant, 6 fingers
f= reccessive, 5 fingers
Ff= 6 fingers( contains dominant gene)
if you combine Ff and Ff you get:
25% FF (6 fingers)
50% Ff (6 fingers)
25% ff ((5 fingers)
so only 25% will have 5 fingers (normal)
Answer2:
Dominant=normal hearing
Recessive= deafness
If one parent is RR and the other Rr, the offspring will be:
50% RR
50% Rr
so all the offspring will have normal hearing, and there is 0% of deafness.
Hope it helps!!
In order from smallest to largest, the ecological levels of organization are
A: biome, ecosystem, community, population, individual
B:community, individual, population, ecosystem, biome
C: individual, population, ecosystem, community, biome
D: individual, populations, community, ecosystem, biome
Answer:
D: individual, populations, community, ecosystem, biome
In order from smallest to largest, the ecological levels of organization are individual, populations, community, ecosystem, biome. So, the correct option is (D).
What is an Ecosystem ?Ecosystems are the complex living organisms and their physical environment and all their concerned correlation in a specific unit of space.
An ecosystem can be classified as
1.Abiotic constituents
It consists of minerals, climate, soil, water, sunlight, and all other non living materials.
2. Biotic constituents
It includes all its living organisms.
By combining these constituents together generates two important forces:
The flow of energy from the ecosystem The galloping of nutrients within the ecosystem.
Ecosystems have varied sizes like some are tiny enough to be encompassed within single water droplets while others are big enough to embody entire topography and regions.
Organic matter engendered by autotrophs directly or indirectly bolster heterotrophic organisms. Heterotrophs are the consumers of the ecosystem which cannot make their own food. They utilize, reorganize, and finally decompose the complex organic substance made up from autotrophs.
Thus, in order from smallest to largest, the ecological levels of organization are individual, populations, community, ecosystem, biome. So, the correct option is (D).

Answer:
Make observations or inferences: In school, most students carry a backpack. Students frequently complain that their backpacks are heavy or hurt their backs.
Ask questions: Do students who carry heavier backpacks report more pain than students who do not?
Construct hypotheses and make predictions: Students who carry heavier backpacks are more likely to experience pain in their back at the end of the school day.
Test hypotheses: Get a sample of students in the school to help with the experiment. All students in the experiment would be students from the school and have no known back conditions. Then weigh the students’ backpacks, and ask the students if they have back pain at the end of the day.
Analyze results: Record the data in a table, and then organize the information by the weight of the backpacks. Group the backpack weights in five-pound intervals (five pounds, ten pounds, etc.) and use a bar graph to show the yes and no responses to the pain question for each student.

Emission lines are lines that are made when wavelengths of light are given off by cooling gases.
O True
O False
Answer:
Its FALSE on edge
Explanation:
When cooling gases emit light wavelengths, lines known as emission lines are created. The first people to notice constellations were the ancient Romans and Greeks.
What Emission lines that are made when wavelengths light?Monochromatic light has a single wavelength and is generated by lasers, which exploit transitions between two atomic energy levels to generate light with an extremely restricted range of wavelengths.
While emission lines refer to the lines of light produced by burning hot gas, absorption lines refer to the tendency of cool ambient gas to absorb the same lines of light.
Some light at specific wavelengths is scattered when it travels through the atmosphere's gas, producing darker bands.
Therefore, It is false that Emission lines are lines that are made when wavelengths of light are given off by cooling gases.

Select all of the following that are a result of heating up a solution?
Molecules will move faster
Molecules will slow down
Molecular movement will not change
More collisions will occur between molecules
Answer:
a
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
The results of heating up a solution are:
Molecules will move faster
More collisions will occur between molecules
According to the kinetic molecular theory, when a solution is heated up:
The temperature of the solution risesThe attractive forces binding the molecules weakensThe speed of the molecules increases. This means that the molecules move faster than before The rate of collision between the molecules increases. This is because of an increase in the Kinetic Energy possessed by the molecules as the temperature risesTherefore, among the given options, the results of heating up a solution are:
Molecules will move faster
More collisions will occur between molecules
