Answer:

A: lower, speed

Explanation:

Enzymes definitely speed up chemical reactions because they are proteins that act as biological catalysts. Catalysts speed up reactions without being used up themselves. They are reusable.

Lowering the activation energy makes the reaction faster because less energy is required to do the same task.

B and C do not make sense because speed activation energy doesn't make sense and slow up doesn't make sense either.

The first event would be the formation of the earth, since in the beginning, conditions were so extreme that life was not possible. The next event would be the origin of life which occurred with the first prokaryotic cells since they are simple cells in structure. Later, there would be eukaryotes, more complex cells, with a nucleus and other organelles such as mitochondria. Eventually, the interaction between cells gave rise to multicellularity and with this, the multicellular organisms were formed, the first ones being plants, followed by reptiles in the Carboniferous and mammals in the Jurassic period. And because primates are mammals, they would be in the last place.

Bison, like cows and elk, have four stomachs. While you might think that bison can eat four times as much as animals with only one stomach, this is not the case.

Active transport is one of the three types of substances transport  accross the membrane. It needs energy to occur because it moves molecules against their electrochemical gradient. Pump protein and carrier proteins are involved in active transport. Phagocytosis, Endocytosis, Exocytosis, Pinocytosis are examples of active transport.

Active transport is one of the three cellular transmembrane types of transport. The other two are passive transport and simple diffusion.

Active transport acts against the electrochemical gradient, so it does need energy to transport substances.

It carries molecules from a low-concentration side of the membrane to a high-concentration side.

The energy used comes from

Carrier proteins are involved in active transport.

Pump proteins, like Na-K pump, expell Na and enters K into the cell.

Among the different types of active transport we can mention endocytosis, exocytosis, pinocytosis, and hagocytosis.

These processes refers to molecules transport mediated by vesicles. It occurs from and into the cell and needs energy to happen because it is active transport.

The effects of the human population on Easter Island led to the ecocide hypothesis.

The island's carrying capacity for sustainable crops was exceeded by human populations, which led to a significant loss of forest cover. Its natural cycle of matter and energy likewise decreased or changed, and as a result, the population fought over the island's limited resources.

They turned to cannibalism since they were short on food and starving. In the years 1862 and 1863, blackbirds also plagued the island. The palm tree seeds are thought to have provided food for the growing rat population, according to archaeologists.

This theory was in line with discoveries made on other Polynesian islands. The rats and human activity would have eventually caused the tree population to dwindle. Hunt used the "rat plague" as the basis for his theory regarding Easter Island's deforestation.

Deforestation can have destructive effects on soils. Trees and shrubs shield the ground from the force of raindrops and provide shade that reduces surface soil temperature, which in turn reduces evaporation. Logging and small-scale removal of trees exposes soil to rain splash which loosens and dislodges soil particles, eroding soil and creating a more impermeable bare surface, which increases runoff.

It was found that the majority of soil fertility indices were affected negatively by deforestation and more than half of the organic matter was lost to deforestation, which, in turn, could lead to deterioration in soil quality or land productivity capacity.

Option A. Both sodium and potassium ions are transported against their concentration gradient.

A concentration gradient happens when the attention of particles is better in a single area than in every other. In passive shipping, particles will diffuse down a concentration gradient, from areas of better awareness to areas of decreased concentration, until they are frivolously spaced.

The statistical test that is common for genetics and tests observed data against the probability of those values is the chi-square test.

A statistical technique called the chi-square test is used to compare actual outcomes with predictions. The goal of this test is to establish whether a discrepancy between observed and expected data is the result of chance or a correlation between the variables you are researching.

What is studied in genetics?

The study of genes and heredity, or how particular characteristics or traits are passed from parents to offspring as a result of changes in DNA sequence, is known as genetics. A gene is a section of DNA that has the instructions needed to create one or more molecules that support bodily function.

Therefore, the chi-square test is a statistical test that is common for genetics and tests observed data against the probability of those values.

Topsoil is the most fertile layer of soil, it is rich in microorganisms, humus and minerals.

the topsoil is the most fertile layer of the soil, in this layer there are a great amount of nutrients and microorganisms that allow the adequate growth of plant organisms. This is why the loss of topsoil after deforestation leads to desertification.

Since topsoil is a nutrient-rich soil, it would allow the growth of plant organisms again even though it is an area exposed to mining processes. Therefore, the answer would be the B option.

The tRNA sequence belongs to the complementary sequence of the mRNA sequence. Although an important conceptual difference is that tRNA goes in separate triplets, while mRNA is a continuos sequence. So, in this case the tRNA will be: UAC - UGA - UCG - ACC - CCC - AUA - AUG - AAA - AUC.

The adaptation that allows the conifers to grow so much taller than the ferns is the presence of vascular tissues such as the xylem and phloem.

The xylem and phloem are two fundamental plant tissues only present in higher plants that are required to transport nutrient products in arborous vascular plants such as angiosperms and gymnosperms.

Therefore, with this data, we can see that the xylem and phloem are two plant tissues that play essential roles in transporting nutrients to all plan tissues in higher vascular plants.

The infraspinatus muscle is included in the rotator cuff muscles.

Infraspinatus muscle are found  on the dorsal surface of the scapula, deep to trapezius, and parts of the deltoid. The infraspinatus is a portion of the rotator cuff muscles composed of the supraspinatus, infraspinatus, teres minor, and subscapularis. These muscles act to stabilize the glenohumeral joint.

The supraspinatus muscle abducts the upper arm. The infraspinatus muscle externally rotates the upper arm at the shoulder. The supraspinatus muscle originates from the supraspinous fossa, which is a concave surface at the top of the scapula. The supraspinatus muscle tendon passes laterally beneath the cover of the acromion.

RNA primers are short dna sequences. In DNA replication, primers pair up with sequences on the lagging and leading strand kickstarting the whole process of replication.

Nucleotides are composed of a sugar molecule (ribose in RNA and deoxyribose in DNA), a phosphate group and a nitrogen-containing base (which can be Adenine, Thymine, Guanine and Cytosine in the case of a DNA). Of those three parts, the only one that changes (and therefore identifies the nucleotide) is the nitrogen containing-base. Therefore, the correct answer is C. base.

Red blood cells will osmotically absorb water from a solution (such as pure water) that has a greater water concentration than their contents, swell up, and rupture. A higher concentration of water outside the cell will diffuse into a lower concentration of water inside the cell.

Osmosis happens when there is an inverse relationship between the concentration of solutes and the gradient in water concentration across the membrane. Osmosis continues to take place until the water concentration gradient is zero or the hydrostatic pressure of the water equals the osmotic pressure.

An animal cell would swell and explode if it were put in a drop of 100 percent pure water. This would occur because osmosis is permitted by the semi-permeable nature of the cell membrane.

At normal pressure and temperature, the water potential of pure water is always assumed to be zero. The kinetic energy that water molecules contain may be used to explain it.
