What is a example of a base being dissolved in water
Answer:NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH-) and sodium (Na+) ions. ... An Arrhenius base is any substance that gives the OH-, or hydroxide, ion when it dissolves in water. Arrhenius acids include compounds such as HCl, HCN, and H2SO4 that ionize in water to give the H+ ion.

What are the products of krebs cycle?
Answer:
What are the Krebs Cycle products? Electron Carriers (NADH and FADH2), ATP, and Carbon Dioxide.
Explanation:
For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced. Each glucose molecule produces two molecules of acetyl CoA, enough for two cycles. These products can be multiplied by two to produce the per-glucose yield. Though only one ATP (or GTP) is produced directly per cycle, the products NADH and FADH2, can produce ATP (or GTP) in a further process of cellular respiration called oxidative phosphorylation. The main function of the Krebs cycle is to produce energy, stored and transported as ATP or GTP. The cycle is also central to other biosynthetic reactions where the intermediates produced are required to make other molecules, such as amino acids, nucleotide bases and cholesterol. The Krebs cycle is found in all cells that use oxygen. Combined with the process of oxidative phosphorylation, the Krebs cycle produces the majority of energy used by aerobic cells with the percentage energy provided for humans being greater than 95%.

A city experiences a heavy rainfall. Days later, when no rainwater is present, rock, debris, and soil fall down a steep hill. Which type of mass movement does this describe? creep landslide mudflow slump
Answer:
I think the answer is landslide
Landslide is the massive movement of material from high altitude to low altitude, producing slope breaks. The correct option is B. The type of mass movement described in the example is landslide.
What is a landslide?A landslide can be defined as a massive movement of materials that include rocks, soil, plants, debris, and other elements composing the ground.
Mass of material moves from high altitude to low altitude due to the action of gravity and the influence of other factors as humidity excess.
These movements occur because the material is exposed to external forces (gravity) that supersede the strength of these materials producing slope breaks.
Other factors such as rains, increase in water level, snowmelt, erosion, earthquakes, human activities, and others influence the landslide occurrence.
The correct option is B. The type of mass movement described in the example is landslide.

Why do you think the Staghorn coral's skeleton is so lightweight?
Answer:
The success of staghorns is partly due to their lightweight skeletons, which often grow quickly enough to outcompete other corals for sunlight, a resource demanded by their photosynthesizing algae. Some staghorn species can grow 4 to 8 inches (10 to 20 centimeters) per year — a blistering speed by coral standards.

Answer:When a plant is eaten by a primary consumer, only 10% of the energy is passed on. ... Decomposers break complex materials into simple components after producers and consumers die, using up the energy they contain. In this way, minerals and elements needed by plants are released in a form that can be absorbed by them.

A scientist at the polar ice cap was studying an ice sample from hundred of meters below the surface. While examining the ice, the scientist found some cells from many years ago. Using an electron microscope, the scientist identified these cell structures: a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes. What kind of organism did the scientist find? (LS1.2)a. plantc. virusb. bacteriad. animal
Answer:
the organism is a plant.
Explanation:
As the scientist, a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes, we can say that it is a eukaryotic cell since it has a differentiated nucleus. Also within eukaryotic cells, plant cells are those that have cell walls.
All structures are typically found in a plant cell.
Why is it more common for birds to have nests with a few eggs rather than just one or a lot?
Explanation:
The large size of a egg makes it difficult for the female to retain more than a single one egg at a time - carrying eggs would make flying harder and require more energy. (Bird eggs vary in size from the tiny 0.2 gramme eggs of hummingbirds to the enormous 9 kilogram eggs of the extinct elephant bird.)
Just as an aircraft cannot fly if it is overweight, all female birds must dispense with the fertile egg as soon as it is formed. And because the egg is such a protein-rich high-nuitrition prize to all sorts of predators, birds must find a secure place to hatch their eggs. Although birds' eggs appear to be fragile, they are in fact extremely robust. The oval shape applies the same rules of engineering as an arched bridge; the convex surface can withstand considerable pressure without breaking. This is essential if the egg is not to crack under the weight of the sitting bird. It takes 26 pounds of pressure to break a swan's egg and 120 pounds to smash the egg of an ostrich.
Female birds have one working ovary, unlike mammals, which have two. Ovaries are the organs where eggs are produced. A bird's ovary looks like a tiny bunch of different-sized grapes.
How does the information from the stimuli get communicated to the brain?
Answer:
Explanation:
Sensory receptor interact with stimuli, such as light sound temperature and pain which is transformed into the code that is carried to the brain by the chain of neurons. Once the signal reaches the end of an axon, which is at the end of neuron, a neurotransmitter is released and the process repeats.
The information is sent in the form of nerve impulses and reaches the spinal cord through the sensory neurons of the PNS.

Why do you think surface waves are the slowest moving waves?
Answer:
S waves are more dangerous than P waves because they have greater amplitude and produce vertical and horizontal motion of the ground surface. The slowest waves, surface waves, arrive last. They travel only along the surface of the Earth.
Explanation:
Answer:
They move a little more slowly than P waves, and can only pass through solids. As S waves move, they displace rock particles outward, pushing them perpendicular to the path of the waves. ... Surface waves are the slowest moving of all waves, which means they arrive the last

The crossing of a hybrid and a dominant purebred will always result in offspring which are what?
Answer:
Dominant
Explanation:
A hybrid trait is also known as heterozygous, which is the combination of the dominant and recessive alleles of a gene. On the other hand, a purebred is combination of the same two dominant alleles or the same two recessive alleles. For example, in the gene coding for height, allele for tallness (T) is dominant over the allele for shortness (t).
A purebred for this trait will either be "TT" or "tt" while a heterozygous or hybrid will be Tt. Hence, according to this question, crossing of a hybrid (Tt) and a dominant purebred (TT) will always result in offspring which are DOMINANT (see attached image).

The study of genes and inheritance is called genetics. In a gene pair, one allele is dominant and the other is recessive.
The correct answer is the variation in gene combination.
What is polygenic inheritance?A character that is controlled by more than one pair of alleles is called polygenic inheritance. The best example is skin pigmentation which is controlled by 6 alleles or 3 gene pairs.According to the question, pigmentation is different due to the combination of the different genes. These genes produced melatonin which decides the skin tone, The dominant genes code for a darker tone, and the recessive gene code for a lighter tone.
Hence, the correct answer is mentioned above.

Within the mitochondrial matrix of mitochondria, the Krebs cycle occurs. In the cytoplasm of the cell, glycolysis happens, hence option C is correct.
What is Krebs's cycle?The Krebs cycle processes occur in the mitochondrial matrix, a dense solution that surrounds the mitochondrial crests in eukaryotes. In addition to water, the matrix also includes all the enzymes, coenzymes, and phosphates required for the cycle's biochemical reactions.
While the majority of anaerobic (without oxygen) and aerobic (with oxygen) respiration respectively occurs in the cytoplasm and mitochondria of the cell.
The cycle occurs in the mitochondrial matrix and results in the production of chemical energy in the forms of ATP, FADH2, and NADH.
Therefore, in the mitochondrial matrix of mitochondria, the Krebs cycle occurs, hence option C is correct.
