PLEASE HELP ME IF YOU DONE THIS BEFORE Part 1: Introduction
Title
Title your lab report with a few words that
summarize the lab investigation
Purpose
The lab report should begin with one or two
sentences that state the purpose of the
investigation what you want to see, practice, loam
about, or test. The purpose statement answers the
question "What am I trying to find out by doing this
experiment?"
The three most common types of labs are:
inquiry labs, in which you measure how
changing one variable affects another variable
discovery labs, in which you observe a scientific
phenomenon, perhaps for the first time.
forensic labs, in which you gather and analyze
data as evidence to build an argument in
response to a question, as in a court case,
All three types of labs give you an opportunity to
learn important scientific skills and concepts.
Question
At its core, science is about inquiry, or the act of
asking questions and seeking answers. Most labs
begin as the result of a question, which is why the
introduction of your lab report should include a
question. For example, suppose you notice that you
seem to play basketball better at the court in one
park than in another. After conducting research, you
realize that one of the surfaces of the court at the
park is different from that of your driveway. As a
result, you might formulate the scientific question
"What effect does the court surface have on the
height that the basketball bounces?" To answer this
question scientifically, you could perform several
experiments and gather data,
Hypothesis (or Prediction)
A hypothesis is an initial answer to a question, a
possible explanation or expectation based on prior
knowledge or research. Before starting most lábs,
you will formulate a hypothesis. It should be listed in
the introduction of your tab report
A good scientific hypothesis states conditions,
expected results, and possible reasons for those
results, For example, you could respond to the
basketball question with a hypothesis like "If the
court surface is smooth concreto, as the park's
court is, then the basketball will bounce higher,
because smooth surfaces have better contact with
the ball." Like this hypothesis, hypotheses are often
structured using the format "il then, because
which is described below.
The "it' portion of the hypothesis describes
something that you will change in the experiment
• The "then" portion of the hypothesis describes
what you think will happen as a result of that
change
• The "because" portion of the hypothesis
describes the ason why you think that change
will occur
In other laboratory activities you will be asked to
make a prediction. You will conduct background
research, then predict the outcome of a known
scientific process
Special Note about inquiry Labs
For inquiry labs, questions are generally
written in the form of "What is the effect of X on
Y?" Hypotheses will generally be in the form of
X [describe how you will change X during the
experiment), then Y will predict how y will
change in response), because give your
reason." In many inquiry labs the variables
lend themselves to a scatterplot (X-Y plot)

After a few hours, the cells of each sponge would re-aggregate and form three new sponges.

We can reach this answer because:

In this case, if three sponges had their composition sieved and mixed, the glycoproteins of their cells would allow each sponge to be remade, as there would be communication and a regrouping of the cells of each sponge.

Answer:

Not every cell in the human body contains DNA bundled in a cell nucleus. Specifically, mature red blood cells and cornified cells in the skin, hair, and nails contain no nucleus. Mature hair cells do not contain any nuclear DNA. ... As part of the maturation process, human red blood cells destroy their cell nuclei.

This means they have no mitochondria, Golgi apparatus, or endoplasmic reticulum. They also lack a membrane-bound nucleus, although they do have genetic material located in a nucleoid region. Prokaryotic cells are surrounded by a plasma membrane, and some types of bacteria have cell walls as well.

Nucleolus. Within the nucleus is a small subspace known as the nucleolus. It is not bound by a membrane, so it is not an organelle. This space forms near the part of DNA with instructions for making ribosomes, the molecules responsible for making proteins.

I am not sure but I think Quizlet is the right answer

Earthworms and bacteria organisms obtain energy from dead or decaying matter.  Thus, the correct option is C and D.

The term "organic matter" refers to material that contains carbon compounds produced by living things. Lawn trimmings, leaves, twigs, branches, moss, algae, lichens, any animal parts, sewage sludge, sawdust, insects, earthworms, and bacteria are just a few examples of what it includes.

The main decomposers in many ecosystems are fungi and bacteria, which utilise the chemical energy in dead matter and wastes to power their metabolic processes. Detritivores, sometimes known as trash or debris eaters, are other types of decomposers. Typically, these are creatures with several cells, like vultures, earthworms, crabs, or slugs.

Answer:

perfect cube shape

Explanation:

the shape of a cell is perfectly cube- shape then its volume must be calculated with an equation:

Height×Width×number of sides and number of boxes

Surface= area of volume ratio is calculated with an equation

Area /volume

if a cell has large surface area to volume into ratio means it has greater exposure to the environment.It means that flow of nutrients and gases move freely in the small cell compared to large cell.

Answer:

In the dehydration synthesis reaction above, two molecules of the sugar glucose (monomers) combine to form a single molecule of the sugar maltose. One of the glucose molecules loses an H, the other loses an OH group, and a water molecule is released as a new covalent bond forms between the two glucose molecules.

Explanation:

i hope this helps anyway

Glucose molecules bond together in a process known as dehydration synthesis. The process includes 1 water molecule is lost (OH + H) for every bond formed. The correct option is C.

Dehydration is a process of chemical reaction in which water is lost. A water molecule is released during the process of making larger molecules out of smaller monomers, which is known as dehydration synthesis.

In the synthesis process, the glucose monomers are bonded together and with each bond, the water molecule is lost in the process. From monomers of glucose, polymers are formed, like starch, and cellulose.

Polymers are formed through the process of dehydration synthesis. These polymers are DNA, proteins, and carbohydrate.

Thus, the correct option is C. 1 water molecule is lost (OH + H) for every bond formed.

Tertiary consumers in a food chain or food web are animals that obtain their nutrients and energy by feeding on other animals within the same food chain or web.

Tertiary consumers are usually at the top of the food chains in their ecosystem. They have the capacity to feed on animals that consume grasses directly (primary consumers) or even on animals that feed on other animals (secondary consumers).

Secondary consumers, on the other hand, are animals that feed on primary consumers. They, at the same time, serve as prey for tertiary consumers in the ecosystem.

Thus, an animal that has the capacity to be both a secondary and a tertiary consumer would have the capacity to feed on other animals as well as be hunted as food by other members of the ecosystem.

Limit fishing around reefs would not help to protect the diversity of coral reefs.

Coral reefs are among the world's most diversified ecosystem and an underwater habitat that is characterized by corals that construct reefs. 

Coral polyps, the invertebrates responsible for reef formation, come in a variety of shapes and sizes, including vast reef-building colonies, graceful flowing fans, and even small, solitary species.

Coral polyp colonies are bound together by calcium carbonate to build reefs.

According to UNESCO, if we continue to generate greenhouse gases at current levels, the coral reefs in all 29 reef-containing World Heritage sites would be extinct by the end of this century.

The Paris Agreement's goal of keeping global average temperature far below 2°C above pre-industrial levels is the only way for coral reefs to survive.

Hence the correct option is B.

Answer:

Explanation:

the path of a nerve signal involved in kicking a ball .When and where do you motor or sensory nerves fire?​

The nervous system is made up of two parts. Each part contains billions of neurons. The first part is the central nervous system. It contains the brain and spinal cord, which is a fibrous, ropelike structure that runs through the spinal column down the middle of the back.

The other part is the peripheral nervous system. It consists of thousands of nerves that connect the spinal cord to muscles and sensory receptors. The peripheral nervous system is responsible for reflexes, which help the body avoid serious injury. It's also responsible for the fight or flight response that helps protect you when you feel stress or danger.

Let's examine an individual neuron up close.

Here is a peripheral nerve. Each one of the nerve bundles, or fascicles, contains hundreds of individual nerve.

Here's an individual neuron, with its dendrites, axon, and cell body. The dendrites are tree-like structures. Their job is to receive signals from other neurons and from special sensory cells that tell us about our surroundings.

The cell body is the headquarters of the neuron. It contains the cell's DNA. The axon transmits signals away from the cell body to other neurons. Many neurons are insulated like pieces of electrical wire. The insulation protects them and allows their signals to move faster along the axon. Without it, signals from the brain might never reach muscle groups in the limbs.

Motor neurons are responsible for voluntary control of the muscles all over the body. The operation of the nervous system depends on how well neurons communicate. For an electrical signal to travel between two neurons, it must first be converted to a chemical signal. Then it crosses a space about a millionth of an inch wide. The space is called a synapse. The chemical signal is called a neurotransmitter.

Neurotransmitters allow the billions of neurons in the nervous system to communicate with one another. That's what makes the nervous system the body's master communicator.
