Answer:
The biological catalysts are enzymes.
Explanation:
Enzymes are proteins that function as catalysts that speed up reactions by lowering the activation energy. The best way to define an enzyme is that it's a biological catalyst that accelerates a chemical reaction without altering its equilibrium.

What is a frequency ?
Answer:
Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. Frequency is measured in units of hertz (Hz) which is equal to one occurrence of a repeating event per second.
Explanation:
Answer: Frequency means the rate at which something occurs or is repeated over a particular period of time or in a given sample.

A(n) _____ is a possible answer to a scientific question, must be based on scientific knowledge.?
Answer:
A hypothesis is a possible answer to a scientific question, but it isn’t just any answer. A hypothesis must be based on scientific knowledge, and it must be logical. A hypothesis also must be falsifiable. In other words, it must be possible to make observations that would disprove the hypothesis if it really is false.
Explanation:
what observations do you have about the bacteria cell
Answer:
Bacteria cells have no membrane bound organelles.Bacteria cells are prokaryotic.Bacteria cells have cell walls.Bacteria cells have strong flexible layers surrounding their cell membranes.Bacteria are called prokaryotes; they lack a nucleus and do not present organelles in the cytoplasm, their observable characteristics are:
The nuclear region of bacteria is not surrounded by a membrane, and consists simply of a single circular double-stranded DNA molecule, which constitutes the bacterium's chromosome (genome).The bacterial cell wall is composed of a macromolecular network called peptidoglycan or murein.The cell wall that gives them their shape and provides mechanical protection, since bacteria are found in environments that can have different concentrations of solute.
Glycocalyx is the polysaccharide-containing structure located on the outer side of the bacterial cell wall.Some bacteria produce flagella, these are long, thin appendages that serve as locomotion organelles.Axial filament a series of fibrils that arise at the ends of the cell below the outer sheath and follow a helical path around the cell.The fibria are structures that enable bacteria to adhere to inert surfaces or to form films on the surface of liquids.Therefore, we can conclude that bacteria are microorganisms that contain structures required for their growth and self-replication, without them these microorganisms lose their integrity.

Bacterial cells are prokaryotic while plant cells are eukaryotic.Bacterial cells have no membrane bound organelles but plant cells have.Answer:
I just had a question on my homework that im still doing so heres what i wrote
Explanation:
A plant cell has chloroplast so that it can make its own food while the bacterial cell does not as the bacterial cell is too small and the chloroplast wont fit. Bacteria cells have flagella so that it can move while plants don't as plants don't move.They both have a cell wall but a bacterias cell wall isn't made from cellulose.The bacterial cell doesn't have its genetic information inside a nucleus it is just in a single loop inside the cytoplasm.The plant cell has a vacuole while the bacterial cell doesn't.The bacterial cell has a slime capsule around the cell, outside of the cell wall. The plant cell is much bigger that the bacterial cell.Plant cells are eukaryotic while Bacterial cells are prokaryotic.Bacterial cells are single celled living organisms while plant cells aren't and they make up a plant.

I'm not so sure.
Auxin is a plant growth hormone (phytohormone) which is responsible for the cell division and large amounts of auxin inhibits the growth of roots in plants. Thus, the correct option is C.
What is Auxin?
Auxins are a class of phytohormones which show some morphogen-like characteristics. Auxins play the main role in coordination of growth and behavioral processes in plant life cycles. These are essential for the development of plant body.
Auxin is a key regulator of growth and development in plant, cell division, elongation and differentiation, development of embryo, root and stem tropisms, apical dominance, and flowering in plants.
In the shoots, auxin hormone stimulates cell elongation and the presence of high concentrations of auxin in plants promote growth. However, in the roots auxin hormone inhibits the cell elongation and therefore high concentrations of this hormone limits growth in plants.

What experimental evidence led to the development of this atomic model from the one before it? A few of the positive particles aimed at a gold foil seemed to bounce back. The colors of light emitted from heated atoms had very specific energies. Equations were used to identify regions around the nucleus where electrons would likely be. Cathode rays were bent in the same way whenever a magnet was brought near them.
Few positive particles aimed at a gold foil seemed to bounce back is the evidence that is responsible for the development of atomic model. Rutherford performed an experiment in which alpha particles are allowed to fire on the gold foil.
Some of the particles bounced back which tell us that there are heavy particles present in the center of an atom.
Most alpha particles pass through the atom which tell us that there is a lot of empty space in an atom.
There is also a slight deflection that occur due to similar charge that tells us the element which is present in the nucleus has positive charge.

2 ways pea plants pollinate
Answer:
Pea plants are naturally self pollinating.......
Explanation:
As they are self pollinating , there's no any way for their pollination . But we can also pollinate the pea plants manually
Answer:
Method 1 : Self-Pollination
Peas are naturally self-pollinating and self-pollination happens before the flowers open.
In self-pollination, pollen grains from anthers on one plant are transferred to stigmas of flowers on the same plant.
Method 2 : Cross -pollination
Peas can be cross-pollinated by hand, simply by ;
opening the flower buds to remove their pollen-producing stamen which prevents self-pollination and dusting the pollen from one plant to the stigma of another.

A willingness to accept different ideas that may not agree with their hypothesis is called what?
Answer:
ad hoc hypotheses
Explanation:
This statement could be used for any hypothesis in which the results (different ideas) do not agree with their hypothesis. In other words, there were no verifiable tests that could make valid the accepted hypothesis.
Thus, the researcher only accepted the hypothesis without a sound basis for doing so.
In the Endosymbiotic Theory for the origin of eukaryotes, the final step was the engulfing a functional cyanobacterium to produce photosynthetic eukaryotes ("plants"). Why is this stage considered the final step in the sequence of eukaryote evolution?
Answer:
The Endosymbiotic Theory of eukaryote evolution is known as Symbiogenesis that states the evolution of eukaryotic cells from prokaryotic organisms.
The engulfing a functional cyanobacterium to produce photosynthetic eukaryotes ("plants") is considered as final step of the eukaryote evolution because a functional cyanobacterium closely resemble the chloroplast and related to mitochondria and it maintains a large genome that encodes thousands of proteins.
A photosynthetic eukaryotes ("plants") require cholorplast (green pigment) for photosynthesis and protein synthesis, which all are provided by functional cyanobacterium, after that a eukaryote can functions as an individual eukaryote and not as prokaryote, and hence engulfing functional cyanobacterium is considered as last step of eukaryote evolution.

1. Which of the following correctly identifies the composition of an oxygen atom?
8 protons, 8 electrons, and 8 neutrons
6 protons, 6 electrons, and 6 neutrons
8 protons, 6 electrons, and 7 neutrons
06 protons, 6 electrons, and 12 neutrons
Answer:
The answer is A. 8 protons, 8 electrons, and 8 neutrons.
Explanation:
This is because Oxygen's atomic number is 8 and its atomic weight is 15.99 units. The atomic number is the number of protons in an atom. This means that there are 8 protons, along with 8 electrons, because the amount of electrons in an atom are equal to the number of protons (not including ions.) Additionally, to discover the amount of neutrons present in the given atom, you must take the atomic weight and subtract the atomic number (aka # of protons present). Once you subtract, you will be left with the number of neutrons. Since the atomic weight is 15.99, you will round it up to 16 and subtract 8, leaving 8 neutrons present. In all, it has 8 protons, 8 neutrons, and 8 electrons.
