In a scientific investigation, after the question is defined, the next step is most likely which of
the following statements?
A. Collecting the data
B. Formulating a hypothesis
C. Designing the experiment
D. Identifying materials needed
In a scientific investigation, the next step after the question is defined is to formulate a hypothesis. A hypothesis is a testable explanation or a prediction. Therefore, the correct option is B.
What is Hypothesis?A hypothesis is the proposed explanation for a phenomenon. For a hypothesis to be scientific, the scientific method requires one to test it. Scientists generally form hypothesis on the basis of scientific hypotheses of previous observations that cannot satisfactorily be explained with the available scientific theories.
Types of hypothesis include simple hypothesis, complex hypothesis, and directional hypothesis.
After the question has been defined, the next step taken by a researcher is to form a hypothesis, or testable explanation. It is about making predictions based on the hypothesis and further test the prediction.
Therefore, the correct option is B.

ANNOTATE Write the inputs and outputs of cellular respiration on this diagram.
Answer:
Inputs---- glucose and oxygen.
Outputs----- ATP, carbondioxide and water.
Explanation:
The inputs of cellular respiration are the glucose and oxygen whereas the outputs of cellular respiration are energy in the form of ATP, carbondioxide gas and water. cellular respiration is a process in which glucose is broken down in the presence of oxygen gas for the production of energy in the form of ATP molecules. Carbondioxide gas and water which are the waste materials also produced in the end of cellular respiration process. Cellular respiration is the reverse of photosynthesis.

Consider the numbers of species known to exist on Earth, including the numbers that are being discovered and
the numbers thought to be going extinct. What do these
numbers suggest about biodiversity on Earth?
Answer:
A high diversity of species is known to exist among insects and land plants; fewer species are known to exist among vertebrates, bacteria, algae, arachnids, Protists, nematodes, mollusks and crustaceans. However, much greater diversity is estimated to exist among insects, fungi, bacteria, algae, and arachnids. Vertebrates are the best-studied organisms but are relatively less diverse than other groups.

Helicase is an enzyme responsible for unwinding the double helix of the DNA by breaking apart the hydrogen bonds between each of the base pairs. Which phase of the cell cycle is helicase most likely active?
A) S
B) М
C) G1
D) G
Helicase is an enzyme responsible for unwinding the double helix of the DNA by breaking apart the hydrogen bonds between each of the base pairs. Helicase is more active in the S phase of the cycle. Option A is the correct answer.
What are the events of the cell cycle?
The cell cycle consists of the interphase and the cell division phase, where the cell division takes a little time in comparison to the interphase. The parent cell spends the majority of its time in the cell cycle's interphase and less time in the cell division phase.
There are three phases in the cell cycle's interphase: G1, S, and G2. The cell grows in both the G1 and G2 phases, while the DNA replicates in the S phase.
Hence, helicase is an enzyme that is responsible for unraveling the double helix of DNA by breaking apart the hydrogen bonds between each base pair. Helicase is more active in the S phase of the cell cycle. Option A is the correct answer.

Mary pushes her cart across the floor with a force of 150N for a distance of 10m. What is the work done on the cart?
Answer:
1500Joules
Explanation:
Work done, denoted by W, can be calculated using the formula:
Work done (W) = force (F) × distance covered (d)
According to the information in this question, Mary pushes her cart across the floor with a force (F) of 150N for a distance (d) of 10m.
Hence, work done (W) by the cart is:
W = 150N × 10m
W = 1500 Newton.metre (N.m) or Joules (J).

Water reacts with minerals in some rocks and very slowly dissolves the rock. What type of weathering does this demonstrate?
Answer:
Salt wedging
Explanation:
Salt wedging is a natural phenomenon which occurs in rocks and stones. It is a physical weathering process. It is a process by which water enters into the small cracks on the rocks and form salt like NaCl and thereby enlarging the cracks.
Most water contains dissolved salts and when water enters into the small cracks of the rocks, the salt begins to grow and it exerts pressures on the walls of the crack thereby enlarging the cracks.
This type of phenomenon is mostly seen near the seacoast and in the arid regions.
Thus water reacts with the minerals in the rock and slowly dissolves the rock in salt wedging weathering process.

Answer:
It is a gel-like matrix composed of water, enzymes, nutrients, wastes, and gases and contains cell structures such as ribosomes, a chromosome, and plasmids. The cell envelope encases the cytoplasm and all its components. Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus.
Explanation:
Flagella, cell wall, and pili are parts of a bacterial cell.
What is a bacterial cell?Microscopically small, single-celled creatures known as bacteria are found in millions in every habitat, both within and outside of other living things.
Some bacteria are hazardous, but most serve a helpful role. They are employed in industrial and medical procedures and sustain a wide variety of living forms, including both plant and animal life.
Around 4 billion years ago, bacteria are assumed to be the initial lifeforms to emerge on the planet. The earliest fossilized creatures are bacteria-like ones. Most biological and some materials can be used as food by bacteria, and certain strains can withstand harsh environments.
New insights into the functions of the gut microbiome are being provided by this expanding interest in how microorganisms affect human health. Bacteria are prokaryotes that do not contain any membrane-bound organelles.
Therefore, flagella, cell wall, and pili are parts of the bacterial cell.

Women gives birth to a baby boy. A few years later she gives birth to another baby boy. What is the probability that her third child will be a girl? Play your reasoning
Answer:
50 %
Explanation:
It is given that a woman gives birth to a baby boy. Her second child is also a baby boy. Now she is about to give birth to her third child. We have to determine the probability of the child to be a girl.
Here, the probability of the child to be a girl would be 50 % or 1 out of 2.
There are two possibilities and the possibilities would result a boy child or a girl child. So there are two possible outcomes and is equally likely with each child birth.
Also each child birth is an independent event, so the probability that the one results will occur do not depend on the previous births.
