Describe what happened to the colored water and the pieces of paper after the holes were punched in the material covering the beaker
Answer:
The paper spreads over the surface of water and the colored water sunk to the bottom.
Explanation:
The paper hole punches were spread over the surface of the water in the large beaker due to lower density of paper as compared to water whereas the colored water had sunk to the bottom. Convection currents is the driving force that caused the pieces of paper to move over the water's surface. At the surface, the water cools and becomes more denser so the coloring sank toward the bottom of the beaker creating convection currents that will leads to the presence of paper on the surface of water.

What type of reaction does catalase facilitate- synthesis or decomposition? Why?
Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.
Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.
What is catalase?
An enzyme called catalase causes (catalyzes) the process by which hydrogen peroxide is broken down into water and oxygen.
Catalase, which is widely distributed in organisms that live in the presence of oxygen, inhibits the buildup of peroxide, which is continuously created by multiple metabolic reactions, and shields cellular organelles and tissues from harm. Catalase is primarily found in the liver of mammals.
Numerous industrial uses exist for catalase. It is used with other enzymes in the food industry to preserve foods, make particular dishes and beverages, and preserve foodstuffs.
Therefore, Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.

which is more common grass or humans?
Answer:
Grass
Explanation:
Cause most human food comes from grasses, directly as grain or indirectly as feed for meat and dairy producing animals.
people- estimate that humans have modified >50% of Earth's land surface.
The grass family, Poaceae, is one of the largest plant families, and, to humans, perhaps the most important, as it includes agricultural grains such as wheat, rice, maize (corn), and sugar cane. The Poaceae comprise about 600 genera and perhaps ten thousand species. It is estimated that grasslands cover about 20 percent of the earth's land area.
so the answer is humans
What are some featured species in the deep sea?
What is so fascinating about our deep blue sea is the fact that there could be so many more species than the ones we know about. Our oceans are so vast and deep anything could really be down there. I don't exactly know what you mean by this question but I can give you some deep-sea creatures that have been discovered, although some sound equivalent to science fiction, they are in fact real.
- Giant Isopod: they are a species of aquatic crustacean. Their appearance is that of a much larger bug, similar to those "rolly polly" bugs. They reside in the deep sea scuttling along the seabed and ultimately harmless to humans.
- Vampire Squid: This creature looks similar to many other squids such as their squid-like bodies and tentacles, however, what makes this squid unique is its black webbed skin (resembling a vampire cape) and its red eyes. The vampire squid's body is covered in photophores that produce light to attract prey.
- Frilled Shark: This is an odd-looking shark that lurks in the deep sea. It looks almost pre-historic and can grow up to a length of 7ft with a typical shark fin further down its back as well as the well-known rows of sharp teeth. Its gills appear to be frilled hence its name.
- Anglerfish: These deep-sea creatures are pretty commonly known. They are frightening-looking fish with long thin teeth lining their mouth and the notable luminescent fin ray that it uses to lure other fish to eat.
So these were just some notable deep-sea creatures that I have heard of and I wrote some information about them. Hope this helped :)

in a cladogram
Answer:
A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny. A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors. A cladogram can be simple, comparing only two or three groups of organisms, or it can be enormously complex and contain all the known forms of life.
Cladogram design is universal, although simple. A cladogram consists of the organisms being studied, lines, and nodes where those lines cross. The lines represent evolutionary time, or a series of organisms that lead to the population it connects to. Nodes represent common ancestors between species. At some point in the past a population of common ancestor organisms was divided, giving rise to the different organisms being studied. Some cladograms show evolutionary time through the scale of the lines, longer lines meaning more time. Some cladograms chose to show extinct species, while others omit them. Any particular cladogram is formulated specifically for the use it is needed.

Explanation:
The overall efficiency of oxidative phosphorylation, assuming standard conditions, can be calculated by comparing the free energy potentially available from the oxidation of NADH by O2 to the free energy required to synthesize 2.5 ATP from 2.5 ADP. This comparison reveals an efficiency of 35%, which is based on the experimental measurement of 2.5 ATP for every NADH oxidized during oxidative phosphorylation. Using this efficiency, calculate the number of ATP generated by each of the following Complexes:
Answer:
The number of ATPs produced wheh efficiency is 100% is 71.42 ATP.
Explanation:
It is known that at the end of Kreb's cycle 10 NADH are produced
Now by using the unitary method
1 NADH produces=2.5 ATP
10 NADH produces=2.5 ATP x 10
10 NADH produces=25 ATP
This is for the efficiency of 35%.
35% efficiency produces ATPS=25
1% efficiency produced ATP=[tex]\dfrac{25}{35}[/tex]
100% efficiency produced ATP=[tex]\dfrac{25}{35}\times 100[/tex]
100% efficiency produced ATP=71.42 ATP
The number of ATPs produced wheh efficiency is 100% is 71.42 ATP.

Kepler's laws describe common features of the motions of orbiting objects, including their elliptical paths around the sun. ... Use mathematical and computational representations of Newtonian gravitational laws governing orbital motion that apply to moons and human-made satellites.
Clarification Statement: Emphasis is on Newtonian gravitational laws governing orbital motions, which apply to human-made satellites as well as planets and moons.
Assessment Boundary: Mathematical representations for the gravitational attraction of bodies and Kepler’s Laws of orbital motions should not deal with more than two bodies, nor involve calculus.
A transcriptional repressor that controls the transcription of gene A is not normally active unless bound by an effector molecule X. In a certain cell, the domain of the repressor that binds to the silencer of gene A is mutated so that the repressor-X complex can no longer bind to its recognition site. With all other factors being the same, what effect do you predict on the transcription of gene A if X is increased in the cell and the cell is already expressing gene A
Answer:
Transcription of gene A is not affected
Explanation:
A transcriptional repressor is a DNA/RNA-binding protein that acts to suppress gene expression and/or protein synthesis by binding to target sequences. Moreover, a silencer is a DNA region that binds to particular transcriptional repressors in order to suppress gene expression. In this case, the transcriptional repressor is activated by binding to an effector molecule X (e.g., another protein). In consequence, and since the activated repressor-X complex is not more able to bind the silencer of gene A, it is expected that such complex will not be able to affect transcription of the target gene.
which of the following best describes how the Sun creates wind on Earth
The energy of the sun heats the land unevenly, creating wind.
What is Earth?Earth, the third planet from the Sun, is the planet where all known life is found. Although the Solar System contains enormous amounts of water, only Earth is home to liquid surface water.
The ocean covers roughly 70.8% of Earth's surface, dwarfing the polar ice, lakes, and rivers. Earth's surface is made up of continents and islands for the remaining 29.2% of its total area.
Several slowly moving tectonic plates that make up the Earth's surface combine to create mountain ranges, volcanoes, and earthquakes. The magnetic field that forms the Earth's magnetosphere and diverts harmful solar winds is produced by the liquid outer core of the planet.
Therefore, The energy of the sun heats the land unevenly, creating wind.

The movement of a substance through the cell membrane that requires energy.
Answer:
The correct answer is - active transport.
Explanation:
Active transport is the movement of a substance that crosses the cell membrane against the concentration gradient and therefore requires energy in the form of ATP. In contrast, passive transport does not require energy for the movement of a substance through the cell membrane as it moves to the concentration gradient.
This movement of molecules is towards the region of high concentration from the region of lower concentration through the cell membrane by elcectrochemical gradient or ATP.
