Answer:
The function of organelles is to provide a specific function for the cell.
Explanation:
Eukaryotes have organelles not prokaryotes. All the cellular processes of prokaryotes occur in one cell. The advantage of having seperate spaces to do various functions is for regulation and maintance.
Explain how Earth's magnetic field is generated.
Answer:
The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.
Answer:
On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet
spindle fibers attach to kinetochores during _____.
Answer:
Metaphase.
In prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores. In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles.
which part of electromagnetic spectrum drives the photosynthetic process in plants?
Answer:
visible ligth
Explanation:
Visible light ranges from low blue to far-red light and is described as the wavelengths between 380 nm and 750 nm, although this varies between individuals. The region between 400 nm and 700 nm is what plants use to drive photosynthesis and is typically referred to as Photosynthetically Active Radiation (PAR).
2. What is the difference between parasitic roots and mycorrhizae?

Water is reabsorbed during filtration by renal capillaries.
Answer:
Most of the solutes get reabsorbed in the PCT by a process called tubular reabsorption. In the loop of Henle, the filtrate continues to exchange solutes and water with the renal medulla and the peritubular capillary network. Water is also reabsorbed during this step.

A scientist hypothesizes that a new medication can reduce the chances of catching a cold. Which of these would most likely be the dependent variable in a study involving this medication?
A - The participants who do not receive the medication
B - The number of participants who catch a cold
C - The age of the participants
Answer:
B - The participants who do not receive the medication
Explanation:
I like to think of the dependent variable as the outcome variable. In this case it would be the number of people that catch a cold because it depends on if they take the medication or not.

Describe three ecosystem services that insects provide?
Answer:
dung burial, pest control, and pollination
The three ecosystem services that insects provide are dung burial, pest control, and pollination.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

area?
Select one:
a. Frontier species
b. Pioneer species
c. Explorer species
d. Pilgrim species
Answer:The answer is b. Pioneer species
Step-by-step explanation; The first species to colonize an area after a major disturbance are called pioneer species; they help to form the new environment. Secondary succession occurs after a disturbance such as a forest fire, where there is still some organic matter to allow new plants to grow.

Explanation:
Identify the independent variable and the dependent variable in your penny
experiment?
Answer:
Independent Variable = The thing you change
Dependent Variable = The thing you measure
Explanation:
An independent variable is the thing that you are changing in your experiment to be able to get different results. For example, if a question says "What will happen to a cup of tea when you change the temperature of the water added to it?"... then the independent variable will be the temperature of the water.
A dependent variable is the thing that you are measuring. For example, if you are studying the amount of light absorbed from different surfaces, then the dependent variable is the unit of light absorbed, which would be measured in Au (Absorbance unit).
You can now take this knowledge and apply it to your question.
How does refrigeration of food prevent it from spoilage?
Refrigeration preserves food by slowing down the growth and reproduction of microorganisms as well as the action of enzymes which cause food to rot. Freezing food slows down decomposition by turning residual moisture into ice, inhibiting the growth of most bacterial species.

The two strands that make up the DNA double helix are said to be antiparallel. What does that mean?
Nucleotides containing adenine base pair with nucleotides containing thymine.
The 5' to 3' direction of one strand runs counter to the 5' to 3' direction of the other strand.
Base pairings create unequal spacing between the two DNA strands.
Answer:
The 5' to 3' direction of one strand runs counter to the 5' to the 3' direction of the other strand.
Explanation:
Antiparallel strands of a DNA molecule means that the phosphate groups at the start of two DNA strands are in opposite position (pole).
The DNA molecule is composed of two strands held together by hydrogen bonds. A single strand is different at its two ends. One end is called 5' (5 prime), the other is called 3' (3 prime). The names come from the notation for the two sugar carbon atoms which participate in the phosphodiester bonds. The different strands in the helix run in opposite (anti-parallel) directions. At each end of the double helix, one strand is 5' and the other is 3'.

Proteins help Store energy and the genetic code. The long chain of amino acids describes the long chain of polypeptides.
What is protein?
Proteins are among the most prevalent organic molecules in biological systems and have a much wider range of structural and functional variations. Many thousands of proteins, each serving a different purpose, can be found in a single cell.
All proteins are composed of one or more chains of amino acids, despite the fact that their structures and activities differ substantially from one another.
In biological reactions, enzymes function as catalysts, accelerating the reactions. Each enzyme may distinguish between one or more substrates, or the molecules that act as the catalysts for the reactions they catalyze.
Therefore, Proteins help Store energy and the genetic code. The long chain of amino acids describes the long chain of polypeptides.
