What is the main source of Earth's light?
Answer:
The Sun
Explanation:
Answer:
The sun
Explanation:
The main source of light on Earth is the Sun. Sunlight provides the energy that green plants use to create sugars mostly in the form of starches, which release energy into the living things that digest them. This process of photosynthesis provides virtually all the energy used by living things.
One change in the body results in another change. This second change reverses the first change in order to maintain homeostasis. This sequence describes a type of
Answer:
Feedback loop
Explanation:
A feedback loop is a process in which the body tends to return to homeostasis if it deviates from normal conditions.
A feedback loop consists o three components a receptor, a control center and an effector.
There are two types of feedback loops namely, positive feedback loop and negative feedback loop.
In a negative feedback loop, the effect of the stimulus is to shut off the original stimulus or reduce its intensity, while in positive feedback loop, intensifies a change in the body's physiological condition.
what are phosphates?
plsss help
Answer:
mineral is a phosphate
Explanation:
Answer:
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid H ₃PO ₄. The phosphate or orthophosphate ion [PO ₄]³⁻ is derived from phosphoric acid by the removal of three protons H⁺ .

Answer:
The study of living and nonliving components of a system can be best described as an. ecosystem ... Describe how you could determine the population size of a specific type of plant in a large forest without counting all of the plants
It is possible to determine the population size of a specific plant in a forest by counting the number of the specific plant in a small section of the forest and then multiply this by the total area.
This technique is known as quadrat sampling.
Quadrat sampling is a methodology by which organisms of a sample of the habitat are directly counted and then this value is used to calculate the total population of an area, i.e., the total number of individuals/organisms in a given area.
In this case, a quadrat delimits a small area in which the specific plant can be estimated.
The abundance of a population in a particular area can be estimated by using the number found per quadrat and then multiply this value by the total size of the area.
Quadrat sampling is a very useful methodology for the study of biodiversity.
In conclusion, it is possible to determine the population size of a specific plant in a forest by counting the number of the specific plant in a small section of the forest and then multiply this by the total area.

Investigator Campbell is in charge of the forensics lab. One of the analysts in the lab ended up with contaminated evidence from the scene of an explosion. Looking through their work area, she sees they have a very small table next to a sink with small nylon bags stored in tight rows at room temperature. What would she advise the analyst to change about their evidence system? The evidence needs to be refrigerated quickly between analyses. The evidence can't be stored in nylon bags at all. The bags can't be kept so close together. They can’t be near the sink—it’s too humid.
Answer:
The bags can't be kept so close together.

What percentage of energy is lost as you move up trophic levels?
Answer: 10 percent
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

8. Which of these is the direct result of an error in the transcription of a DNA
nucleotide?
A. Amino acids do not bond to tRNA.
B. Transportation of mRNA does not occur.
C. The nuclear membrane is ruptured.
D. RNA sequence is incorrect.
CLEAR ALL
Answer:
D. RNA sequence is incorrect.
Explanation:
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
When a RNA sequence is incorrect, it leads to an error in the transcription of a DNA nucleotide.
This ultimately implies that, an error in the transcription of a DNA nucleotide is the direct result of an incorrect codon sequence (RNA nucleotides).

1. Make a prediction of how self-control impacted the GPA of the students in the study and explain WHY you think so. 2. Then answer one of these questions: What helps you control yourself?
What makes you feel out of control?
What makes you fearful?
What helps you feel calm?
Answer:
Explanation:
1. A study conducted by Tangney, Baumeister, and Boone, indicates that self-control not only could predict GPA, but also better adjustment, better interpersonal, secure attachment, and more optimal emotional responses.
2. Start by slowing your thinking down. Take slow deep breaths. Take yourself to a quiet place. By learning how to recognize our inner emotions and thoughts, name them, and let them pass through us, we can practice more self-control, which also helps build greater agency.
