Explanation:
we need to see the laboratory experiment to answer this question. But according to my search, the answer may be the following:
Stems in these plants exhibit positive phototropism and grow in the direction of a light source. Photoreceptors in plant cells detect light, and plant hormones, such as auxins, are directed to the side of the stem that is furthermost from the light.

Which interest group opposed the U.S. Clean Water Act?
A) citizens of small towns that lacked water treatment facilities
B) mayors of large cities such as New York and Chicago
C) duck hunters
D) owners of printing companies in Tennessee
None of the interest groups mentioned opposed the U.S. Clean Water Act. In fact, the Clean Water Act was passed with broad support from a variety of stakeholders, including environmental groups, industry, and government agencies.
What is the Clean Water Act?The Clean Water Act (CWA) is a federal law enacted in 1972 with the aim of regulating and protecting the nation's waters from pollution and contamination. The CWA established a framework for controlling and limiting the discharge of pollutants into navigable waters, including rivers, lakes, and coastal areas, and set water quality standards to ensure that waters are safe for human use and aquatic life.
The Act provides a regulatory framework for permitting discharges of pollutants, sets water quality standards for contaminants, and establishes a program for regulating the discharge of pollutants from stormwater runoff. The CWA has been amended several times to strengthen its provisions, and it remains a critical tool for protecting water resources and public health in the United States.

These are composed of intersecting horizontal and vertical lines that form a cartesian plane.
, The number plane, or Cartesian plane, is divided into four quadrants by two perpendicular lines called the x-axis, a horizontal line, and the y-axis, a vertical line. These axes intersect at a point called the origin. Once a unit distance has been chosen, the position of any point in the plane can be uniquely represented by an ordered pair of numbers (x,y). For the point (5,3), for example, 5 is the x-coordinate and 3 is the y-coordinate, sometimes called the first and second coordinates. When developing trigonometry, the four quadrants are usually called the first, second, third and fourth quadrants as shown in the following diagram.

If there is a change in a squid's messenger RNA, this change does not appear in its genetic material. This change neither will be inherited by its offspring.
What is messenger RNA?During gene transcription, a fragment of DNA called gene is used as template to generate a messenger RNA (mRNA).
Subsequently, this mRNA is used as a template to create a protein by a process known as translation.
The mRNA is a molecule that carries the genetic material from DNA to protein but this process does not modify the genetic material.

Pioneer species move into an area after a disturbance that forms new land without soil.
Pioneer species are the first organisms to inhabit a region that has experienced a primary succession.
How do pioneer species arrive?
Primary succession begins in barren areas, such as on bare rock uncovered by a retreating glacier.
The first residents are lichens or plants that can survive in such an environment. Over hundreds of years these “pioneer species” transform the rock into soil that can support simple plants such as grasses.
Thus, Pioneer species move into an area after a disturbance that forms new land without soil.

What are muscles?Muscles are a special type of tissue that has the ability to contract in response to a given stimulus.
There are different three types of muscle fibers: cardiac muscle, skeletal muscle and smooth muscle.
Cardiac muscle and smooth muscle are involuntary muscles, whereas skeletal muscle is a voluntary muscle.
Learn more about skeletal muscle here:
https://brainly.com/question/1283837
Answer:
Involuntary: Smooth
Voluntary: Skeletal
Electrical Nodes: Cardiac
Tendons: Skeletal
Digestive Tract: Smooth
Arteries: Smooth
Extensors: Skeletal
Explanation:
Types of muscles. The three kinds of muscle in the body are the skeletal muscle, the smooth muscle, and the cardiac muscle. The skeletal muscles are attached to the bones and allow one to move at will. Because the skeletal muscles are mostly under your conscious control, they are sometimes called "voluntary" muscles. Smooth muscle lines the inside of such hollow organs as the digestive system, bladder, and arteries. Smooth muscles work automatically and are beyond your conscious control. They are referred to as "involuntary" muscles. Cardiac muscle is unique to the heart.
Although skeletal muscles seem to be under your control, a lot happens of which you are not aware. First of all, your posture, even when asleep, is controlled by skeletal muscles without your paying much attention to it. Your mouth, for instance, would flap open if your brain did not maintain a certain tension in your chewing muscles all the time. Your chin would spend a lot of time resting on your chest if your neck muscles didn't hold your head up. And your movements of all kinds would be pitifully awkward if your cerebellum did not coordinate all the muscles necessary to perform even the simplest actions. Just scratching your nose, for instance, requires dozens of muscles to move in exactly the right way at exactly the right time. You are truly "fearfully and wonderfully made."
We will now take a closer look at the other two types of muscles. Skeletal muscles can be attached to other muscles or to bones either directly or by a thin band of connective tissue called a tendon. Do not confuse this tendon with a ligament, which connects bone to bone and not muscle to bone. Two good examples of tendons can be found in the back of your legs. One is the Achilles tendon which attaches the calf muscle in the lower back part of your leg to your heel. The other tendons are on the back side of your knee, called the hamstrings. They serve to attach muscles in the upper back part of the leg to the bones of the lower leg and flex your knee. Locate these structures on your own leg.
The point at which a muscle is attached to the less movable part of the body is called the origin. The point at which a muscle is attached to the more movable part of the body is called the insertion. The biceps muscle of your upper arm is a good example of both these points. The biceps has its origin in your shoulder and its insertion in the bones of the forearm.
Skeletal muscles differ relative to their effect on the body. Those muscles that bend a joint are called flexors, and those muscles that straighten a joint are called extensors. Muscles always work in pairs, one opposing the action of the other. For instance, the upper arm has biceps on the front, which serves as the flexor. The muscle that opposes this motion and serves as the extensor of the forearm is the triceps, which is located on the back of the upper arm. When one muscle contracts, the other must relax. Study the diagram and then see if you can feel the alternating contraction of the biceps and triceps in your own upper arm as you bend and straighten it.
You should be careful to get enough exercise to keep your muscles in good shape. Muscles will grow larger and have better tone, which means they will always be slightly contracted, if they are used. If a person is lazy or is confined to a bed or wheelchair for a prolonged period of time, the muscles not being used will become smaller and lose their tone. This condition is called atrophy. A muscle atrophies at a rate of about 1% a day, so that it will lose a full third of its strength after a month of disuse. Disuse also causes bones to soften by losing their calcium. "Use it or lose it" is a solid maxim of physiology.

Differentiate between biotic and abiotic components.
Non-living physical and chemical elements in the ecosystem are referred to as abiotic factors. Typically, abiotic resources are obtained from the lithosphere, hydrosphere, and atmosphere [e.g. water, aer, soil, sunlight, and minerals].
Biotic factors are organisms that are alive or were onse alive in an ecosystem. These are obtained from the biosphere and have the ability to reproduce [animals, birds, plants, fungi, and other identical organisms].
