Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Explanation:
Maybe this will help?
Enzymes are proteins that speed up the biochemical reactions in living organisms, and they are biological catalysts. Enzymes are substance-specific, each one controls only one type of reaction. They are denatured by high temperatures and by extremes of ph.
What are enzymes?Enzymes are biocatalysts made up of proteins, that increase the speed of the reaction.
Enzymes do not involve in the reaction and in the end of the reaction they separate from the reaction their substance is specific they are specific to reactions whose speed is increased by these enzymes.
In high temperatures and pH their structure changes as they are protein and with extreme where they also get the nature
Thus, the blanks are a. proteins, b. reactions, c. catalysts, d. Substance-specific, e. denatured.

I need a small text (about 50 words) for the human brain.
Answer:
The human brain is the command center for the human nervous system. It receives signals from the body's sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than any other brains.The largest part of the human brain is the cerebrum, which is divided into two hemispheres, according to the Mayfield Clinic. Underneath lies the brainstem, and behind that sits the cerebellum. The outermost layer of the cerebrum is the cerebral cortex, which consists of four lobes: the frontal, parietal, temporal and occipital. [Nervous System: Facts, Functions & Diseases]
Like all vertebrate brains, the human brain develops from three sections known as the forebrain, midbrain and hindbrain. Each of these contains fluid-filled cavities called ventricles. The forebrain develops into the cerebrum and underlying structures; the midbrain becomes part of the brainstem; and the hindbrain gives rise to regions of the brainstem and the cerebellum.

Which structure separates an animal cell from its surrounding environment? (1 point) 1 Golgi apparatus 2 plasma membrane 3 nuclear membrane 4 central vacuole
Answer:
2) plasma membrane
Explanation:
The structure that separates the cell from its surrounding is plasma membrane, the correct option is 2.
What is plasma membrane?The plasma membrane, also renowned as the cell membrane, is the membrane located outside all cells that distinguishes the cell's interior from its surroundings.
A cell wall is attached to the plasma membrane on the outer of the plasma membrane of bacterial and plant cells.
The semi-fluid living matter in the cell is called protoplasm or in other words simply plasm. This living matter, or one can say plasm, is contained within the plasma membrane, a biological membrane.
Lipids which are phospholipids and cholesterol, proteins, and carbohydrate groups attached to some of the lipids as well as proteins are the primary components of the plasma membrane.
A phospholipid is a sort of lipid that is created by glycerol, two fatty acid tails, and a phosphate-linked head group.
Thus, the correct option is 2.

What are the five main phases of the cell cycle? What are the main events in each?
Answer:
In the adult organism, mitosis plays a role in cell replacement, wound healing and tumour formation. Mitosis, although a continuous process, is conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase and telophase.
Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA.

A galaxy has less mass than a moon and more mass than a planet.
True
False
Answer:
False, major false. A galaxy is a small portion of the entire universe... it contains plants, stars, asteroids, moons are insignificant compared to it. Also, pretty much all moons are larger than planets so that wouldn't even make sense.
Answer:
FALSEExplanation:
First off a galaxy is one of the largest things in space, besides things like galaxy clusters.
Second all planets have more mass than the moon. Since planets have more mass than a moon, it is impossible to have less mass than a moon but more than a planet.
Finally, a galaxy is made up of millions of planets and moons. So it does not make any sense nor is it even possible.
Water that infiltrates into the ground is called ___________.
A. runoff
B. groundwater

Answer: B Infiltration
Explanation: The process by which water penetrates the ground to become groundwater is called b. infiltration. Runoff is water that flows on the earth's surface after a shower of rain. This water usually flows into rivers or streams. Precipitation can occur as rainfall, snow, hail or sleet and falls from clouds when condensation occurs. Transportation is the process by which trees release water vapor into the atmosphere via stomata in the leaves.

When energy is added to a wave, how can the wave change? Select all that apply
Explanation:
The amplitude can increase The frequency can increase Deceased wavelengthWhen energy is added to a wave, the wave changes with the following:
The frequency can increase.The wavelength can decrease.The amplitude can increase. What do you mean by Energy?Energy may be defined as the ability to do work. It is applied to an object to increase its velocity. It is something that defines how things change and move.
Frequency is inversely related to the wavelength and directly related to the amplitude. So, if frequency increases, the amplitude is also increased, but the wavelength decreases.
Frequency is defined as the number of peaks formed by the wave in 1 second.
Therefore, when energy is added to a wave, frequency and amplitude increase, while wavelength decrease.
