Haley knows that plants and animals are made up of many different materials. She wants to know how these materials can cycle through an ecosystem.
What question could Haley ask to learn more about this topic?
A.
What kind of organism is the most popular at Haley's school?
B.
What happens to the materials that make up a living organism after it dies?
C.
What will happen to a sunflower plant if it is grown in a dark closet?
D.
What kind of plant should Haley buy her mom for her birthday
Answer:
B. What happens to the materials that make up a living organism after it dies.
Explanation:
An ecosystem can be defined as the natural living habitats of both living and non-living organisms.
Ecosystem services such as plant pollination, nutrient cycling and water purification are essential services that are being provided by the ecosystem. These services are really very vital, important and useful for the sustenance of life, both for humans, plants and animals because they enhance social welfare.
In this scenario, Haley knows that plants and animals are made up of many different materials. She wants to know how these materials can cycle through an ecosystem. Therefore, the question Haley could ask to learn more about this topic is; what happens to the materials that make up a living organism after it dies?
Basically, the material that make up a living organism decomposes after it dies and are then used up as nutrients by plants growing on the soil.

What is a SNP mutation?
Answer:
Explanation:
Single nucleotide polymorphisms, frequently called SNPs (pronounced “snips”), are the most common type of genetic variation among people. Each SNP represents a difference in a single DNA building block, called a nucleotide.Most commonly, these variations are found in the DNA between genes.
single nucleotide polymorphism
A single nucleotide polymorphism, or SNP (pronounced "snip"), is a variation at a single position in a DNA sequence among individuals.
Each SNP represents a difference in a single DNA building block, called a nucleotide. For example, a SNP may replace the nucleotide cytosine (C) with the nucleotide thymine (T) in a certain stretch of DNA. Most commonly, these variations are found in the DNA between genes.

why cats hate pickles hahahhahahah
Answer:
"Anything that looks like a snake should produce the instinctive fear response," Slobodchikoff said. “Cucumbers are shaped more like snakes, with their curving sides, than ears of corn or eggplants, so they produce a greater response."
But don't go trying to prank your cat with cucumber-shaped objects just yet. Scaring cats can have long-term effects on their mental health.
"Anytime you scare an animal, you risk inflicting psychological damage, so that the animal will be afraid not only of cucumbers,” Slobchikoff said, “but also the surroundings in which the cucumber was presented to the animal.”

How does a tree grow? Explain in detail
Answer:
Trees grow in height as a result of meristems that are located at their branch tips. These meristems are called apical meristems. ... The vascular cambium produces new xylem and phloem each year and as a result, the trunk, branches, and roots continue to increase in diameter.
Explanation:
hope this helps have a good rest of your day :) ❤
Answer:
in botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world.

what is the function of DNA, and why is it called the heritable material
Answer:
DNA is an information molecule.
Explanation:
WHAT IS THE FUNCTION OF DNA?
DNA stands for Deoxyribonucleic acid.
It allows the body to tell it how to make larger proteins. It contains 46 chromosomes.Chromosomes are 1 strand of DNA. (Imagine your hair. Your whole head of hair is like DNA, if you were to pull out 1 string of hair, it would be a chromosome.)WHY IS IT KNOWN AS A HERITABLE MATERIAL?
It is known as a heritable material because your parents pass their genes onto you.
(If you cut your 1 strand of hair (chromosomes) into pieces then it would be a gene.)
Part of your fathers genes and mothers genes join to make up your DNA by passing on their genes to you.

Explanation:
What is the energy released from ATP used for?
A farmer decides to test whether or not a fertilizer will make her crops grow bigger. In year 1, she plants corn in two different fields on her property and fertilizes one and not the other. She measures the height of 10 corn plants in meters from each field. She takes her measurements every week for three months. In year 2, she puts irrigation in one of the fields and conducts the same experiment.
Required:
a. What is the independent variable and the treatments (increments) used in the experiment?
b. What is the dependent variable and the units in which it was measured?
c. Name at least two controlled variables:
d. What is the hypothesis?
e. Identify two sources of error in the first year in the experiment:
f. Identify two sources of error in the second year in the experiment:
Answer:
a. independent variable: the fertilizer.
treatments: the use of fertilizer in one of the fields.
b. dependent variable: the crop growth in height.
units: meters
c. two controlled variables: soil pH / solar-radiation exposure, and water supply
d. hypothesis: the fertilizer makes the crops grow bigger.
e. two sources of error in the first year:
the researcher might plant the two crops under different conditionstake wrong measures of the height of the cornsf. two sources of error in the second year:
she can fail in irrigating the crops climatic and environmental conditions might change and have different consequences on each of the fields (this source affects the results influencing the growth of the plants).Explanation:
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. These changes allow analyzing its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the fertilizer is the independent variable. Treatments: Refers to the experimental procedure applied in the experimental group. In this example, the use of fertilizer is the treatment. Here the experimental group (the one that receives the experimental procedure, with changes in the independent variable) is the fertilized field. Data from the experimental group is compared with the data from the control group, to analyze the effects of the fertilizer.Dependent variable: The values of these variables respond to any change in the independent variable. It represents the quantity of something. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. In the exposed example, the crop growth rate in height is the dependent variable, that depends on the fertilizer used in that field. The units in which the crop is measured are meters in height. Controlled variable: Refers to those variables equally applied to every group or subject in an experiment and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example, soil pH and solar-radiation exposure can be two controlled variables, as they must be equal for both fields. Water supply by irrigation ducts during the second year in both fields is also a controlled variable. Hypothesis: A hypothesis is a possible answer for a question, a speculation that is not verified yet and requires corroboration. A hypothesis must express what is expected to occur in a perfectly comprehensive manner. It must be objective and directly related to variables. In this example, the hypothesis might be that the fertilizer makes the crops grow bigger. Errors: These are the differences between the observed data or taken values and what is really happening in nature, which can lead to a misinterpretation of what is actually going on. These errors might be systematic mistakes performed by the researcher when measuring, taking data, applying the treatment, etc. Or they might be due to random errors, which are due to failures in the instrumentals, changes in the environment, a single mistake of the researcher while taking measures, among others. During the first year, the researcher might plant the two crops under different conditions (parcels with different slopes which affect solar-radiation) or might commit a mistake while applying the fertilizer (different concentrations for example), or might take wrong measures of the height of the corns. During the second year, she can fail in irrigating the crops correctly, providing more water to one of the fields. She can commit the same measuring mistakes. Or even climatic and environmental conditions might change and have different consequences on each of the fields.
