Answer:

A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. Enzymes are proteins that act as catalysts in biochemical reactions.

Answer:

passed on, inherited, passed on to offspring, most adapted to the environment or have the best adaptive traits or higher genetic fitness

Explanation:

Natural selection results in change over time by acting on traits that are heritable and advantageous.

Natural selection is the differential survival and reproduction of individuals due to the differences in phenotype of the organism. Natural selection is a key mechanism of evolution, the change in the heritable traits characteristic of a population takes place over many generations.

Natural selection is the central mechanisms of evolutionary change in a species and is the process responsible for the evolution of adaptive features in an organism. This selection helps in storing the characteristics which are advantageous and are heritable for the species.

Answer:

Homeostasis is important to enzymes because the body would not be able to function properly.

Explanation: (This is a direct answer from the Web)

The maintenance of the conditions by homeostasis is very important because in the wrong body conditions certain processes (osmosis) and proteins (enzymes) will not function properly. ... The body's temperature must be kept at 37 degrees because this is the temperature at which enzymes optimally function.

Answer:

Silk is beautiful, highly-desirable and pricey. Do you know how it is produced?

Silkworms are the offspring of moths . They spew out thread from tiny holes in their jaws, which they use to spin into their egg-bearing cocoons. This entire production takes a mere 72 hours, during which time they produce between 500-1200 silken threads. These miniature, mulberry leaf-munching marvels lay, at minimum, 500 eggs each spring, thereby increasing the number of workers for the production line.

The ancient Chinese unearthed the silkworm's secret, and were the first to spin the silkworm's threads into cloth. They kept this covert, top-secret operation, from the rest of the world by imposing the death sentence upon those who smuggled the worm or its eggs out of China. Eventually, however, the secret was out, and silkworms are now farmed for their silk, in China, of course, in Japan, in India, in France, in Spain, and in Italy. These countries harness the power of the silkworm through a tedious, labor-intensive, time-consuming process, a process which prominently figures into the price of silk.

Farm workers painstakingly place the 500 plus eggs the grayish-white moth lays, upon strips of paper or cloth, until the following spring, when the incubated eggs hatch, and the tiny, black worms emerge. Once hatched, workers transport the worms to trays brimming with the worm's favorite fodder of finely chopped, white mulberry leaves. After approximately 6 weeks, the satiated worms begin slowly to sway their heads back and forth to signal that show time is at hand.

Once the silkworm completes its cocoon, the farmer snatches his cocoon from him, to prevent the shrunken chrysalis, carefully encased inside, from hatching into a moth in 12 days. The silk farmers ensure that this event does not transpire, and does not kill his moneymaking venture, by exposing the cocoons to heat, thereby executing the chrysalis. Now, the silkworm's labor of love is prepared for the silk production process.

The process begins by bathing the now-empty cocoons in troughs of warm water, which serves to soften the gum binding the silken filaments together. He now proceeds with the arduous task of unraveling several cocoons, and winding the filaments onto a reel that twists 10-12 filaments together into a "single" thread of silk. The end product is a skein of raw silk, which the farmer profits from by selling to the highest bidder.

Answer:

Hypotonic solution

Explanation:

Haemolysis of red blood cell refers to the destruction or breakdown of red blood cells. Red blood cell will undergo haemolysis if placed in an Hypotonic solution. Hypotonic solution is a solution that contain smaller amount or lower concentration of solutes like dissolved salt than other solution and also compared to the cystol. If a cell is placed in Hypertonic solution, red blood cell will swell because it will absorb solute and undergo hemolysis burst when placed in a hypotonic solution.

Answer:

Option A is correct

Explanation:

Given  

Pika are eaten by many animals of the grass land. The burrows of Pika are helpful in draining the ground water rapidly and the burrows also acts as nesting site for many bird species. Pikas consume grass and hence they are competitors of livestock animals.  

Removing Pikas from this ecosystem will destabilise the ecosystem as all the grass land predators will not get sufficient food. If Pika will not be there, then their burrows too will not exist and hence the excess ground water cannot be absorbed. Also the bird species will not be able to use burrows as nesting site.  

Hence, option A is correct

Explanation:

Complete question:

Directions: Read the descriptions of the four islands presented in the lesson.

1. List two new traits that each new species of rat might demonstrate as it adapts to the conditions on each island.

2. Introduce one of the four new rat species to another island and describe one challenge it would encounter and one success as it adapts to its new environment

Island A:  

The island is fairly flat with an occasional hill. The ground is made of soft dirt, and several species of shrubs grow toward the center of the island. There is no animal life on land, but the water around the island is teeming with fish. The island is surrounded by a coral reef, and the shore is sandy with no algae growing on it. Freshwater is available.

The rat on Island A:

1.

2.

Island B:

This island has a rocky shoreline. Numerous tide pools dot the island along the shore where the wave action is somewhat sheltered by rocky outcrops. The tide pools host barnacles, abalone, sea urchins, and crabs. Algae grow all around the island; however, the growth of algae is quite sparse in the tide pools where the various animals feed. The current is quite strong along the rocky outcrops where the algae grow best. Freshwater is available.

The rat on Island B:

1.

2.

Island C:

The island is somewhat barren. A few species of cactus thrive on the bare rocks, and a large, cactus eating tortoise inhabits the island. A species of very large birds’ nests on the island annually. The birds build their nests on the rocks and protect their eggs from the sun by standing over the nests with outspread wings. The nests are always found on the windy side of the island, which is somewhat cooled by offshore breezes.

The rat on Island C:

1.

2.

Island D:

This island is an extinct volcano. Vegetation on the island changes as the altitude increases. Grasses grow at the base of the volcano, but farther up the volcano’s slope, the grasses give way to low shrubs. Halfway up, the island becomes quite lush; tropical plants and trees dominate the landscape. At this altitude, the island experiences frequent rain showers. Two species of birds inhabit the island. One is a raptor that preys on the smaller birds. The other fishes the waters approximately one mile offshore. Both of the bird species nest in trees.

The rat on Island D:

1.

2.

Answer:  

The rat on Island A:

1. Behavioural adaptation → Diurnal habits, as there are no predators that might attack them.      

2. Morphological adaptation → Flat feet to move on the sand and Long strong nails to dig in the soft dirt and reach the roots of the shrubs which are a nutritious source of food.

The rat on Island B:

1.  Morphological adaptation → Strong extremities to move along the rocky shoreline, to avoid sudden wave impacts, and handle to swim counter-current if they fall.

2. Morphological adaptation → Strong mandibles, well-developed masseteric and temporal muscles, and teeth adapted to feed on barnacles, abalone, sea urchins, and crabs.

The rat on Island C:

1.  Stress-induced → Reduced transpiration rate due to the limited water availability.

2. Behavioural adaptation →  Skills to compete for scars food with the tortoise avoiding its attack or presence.  

The rat on Island D:

1.  Morphological adaptation → Waterproof coat, due to the frequent rain showers.

2. Morphological adaptation → Vestigial nails, as they do not need them to get food.
