Kudzu is a Japanese vine of the family of peas known to be an invasive plant in North America.
This plant grows horizontally by runners and rhizomes, its vine roots where it comes in contact with the ground and creates new plants.
The growth rate of this plant is about 30 feet per day, which is why it can cover large areas in a rela-tivelly short time period. This vine covers the native plants and trees covering the sun and air, which smothers and suffocates them. Since it is an invasive species, for example in the US, it does not have natural predators and outcompetes the native species for resources. As it competes with the native species, it disrupts the food chain because it threatens the plants that animals use for food and shelter and its roots modify the amount of water and nutrients that are in the soil.
This plant releases the chemicals isoprene and nitric oxide that when combined with the nitrogen of ozone can cause health troubles for humans.

Explain how the scientists are able to determine the liquid and solid layers. Use at least two pieces of evidence to support your answer.
Answers
Scientists rely on seismic waves that travel through earth and across its surface in order to reveal the structure of the interior of the planet i.e. liquid and solid layers.
What should we do to determine the different layers?Scientists use waves to study the different layers of the earth usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test density of liquid explosions. The seismic waves are bent, sped up, slowed down, or even reflected when they pass through the earth's layers. Different types of materials density of the liquid. A liquid is a sample of matter that conforms to the shape of a container in which it is held, and which acquires a defined surface in the presence of gravity. There is evidence density of liquid that the materials within the earth form distinct layers, each with a different density of the liquid. Scientists learned that the outer core is liquid by analyzing earthquake waves. The inner core is a dense ball of solid iron crystals.
So we can conclude that seismic waves are produced the vibrations generated by earthquakes or explosions.

How do the muscular and skeletal systems work together to make the human body move? A. They provide nutrients to the body B. They provide oxygen and carbon dioxide to the body C. The provide blood to the body D. They provide structure and movement to the body
Answers
The muscular and skeletal systems work together to make the human body move as: D. They provide structure and movement to the body.
The muscular and skeletal system is also known as the musculoskeletal system. The bones of our skeletal system work on protecting the body's organs, support the weight of our body and provides shape to our body. The muscles of the muscular system which are attached to these bones, pull on them to allow the movement of the body.
The muscles in our body can pull the bones, but they can't push them back to their original position. Therefore, they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint. After the movement is complete, the flexor relaxes and the extensor contracts to straighten the limb at the same joint.

Should you always begin observation of specimens with oil immersion lens?
Answers
You should always begin observation of specimens with oil immersion lens is false.
What are specimens?Specimens are defined as a single plant or animal that is studied by scientists and serves as an illustration of a specific species or type. Any material derived from a human, including blood, urine, tissues, organs, saliva, DNA/RNA, hair, nail clippings, or any other cells or fluids, is referred to as a human biological specimen, whether it was gathered for research or was left over as a specimen after a diagnostic, therapeutic, or surgical procedure.
When you have a sample that is only a few tens to one hundred micrometers thick, you should utilize an oil immersion lens. You should utilize it specifically when the structures you want to see are very small, possibly one or two micrometers in size or smaller.

Smithers thinks that a special juice will increase the productivity of two groups of
50 workers. He creates two groups of 50 workers each and assigns each group
the same task (in this case, they're supposed to staple a set of papers). Group A is
given the special juice to drink while they work. Group B is not given the special
juice. After an hour, Smithers counts how many stacks of papers each group has
made. Group A made 1,587 stacks, Group B made 2,113 stacks.
Use this scenario to answer questions 1-4
1. Identify the control group
A: Group A
B: Group B
C: There is no control group
2. Identify the independent variable
a: Amount of pages stapled
b: Special Juice
c: Stapler
3. Identify the dependent variable*
a: Special Juice
b: Stapler
c: Amount of pages stapled
4. What should Smithers conclusion be?
a: Group A made 1,587 stacks and Group B made 2,113 stacks of paper therefore the special drink DID work
b :There isn't enough evidence to make a conclusion
c: Group A made 1,587 stacks and Group B made 2,113 stacks of paper therefore the special drink DID NOT work

How does oxygen reach the cells of the body? Explain how the respiratory and circulatory systems work together to supply cells with the materials they need?
Answers
According to the research, the respiratory and circulatory systems have the anatomical structures responsible for pumping and distributing blood throughout the body.
How the respiratory and circulatory systems work together?The circulatory system has the main function of transporting blood throughout the body; this blood will contain nutrients and oxygen so that they reach all the cells where the respiratory system is responsible for capturing oxygen.
In this sense, this process is carried out by means of two circuits that process blood with oxygen and deoxygenated blood:
Systemic circulationPulmonary circulationVeins that contain oxygenated blood, such as the pulmonary veins, carry oxygenated blood from the lungs to the heart.
Therefore, we can conclude that the respiratory and circulatory systems work through two circuits to transfer oxygen and nutrients from the blood to the cells.

Answer
A diffusion
B) osmosis
C) active transport
D facilitated diffusion
Answers
Therefore, D, which stands for facilitated diffusion, will be the answer to this issue. Thus, one transport protein carries the molecules from across the membrane during assisted diffusion.
Active transport is affected by what particles?The process that includes the of pumping molecules and ions across membranes in “uphill” direction – against a concentration gradient – is known as active transport.
Transport proteins that are present in the membrane are typically responsible for the active transport of small molecules or ions across a cell membrane.
Do you mean active or passive aided diffusion?Passive transport can be said as a subset of facilitated diffusion.
Because the solution is going down the concentration gradient, assisted diffusion is still passive transport and when it incorporates transport proteins. The cell can easily disperse small nonpolar compounds.
