Well to be honest there are no unmistakable separating lines. Each layer mixes into the layer above it and the layer underneath it. Researchers are certain that the air becomes thinnerand more slender farther from the Earth's surface, until it at long last blurs off into space.

An astronaut is in a sleeping bag attached to a wall. When astronauts sleep in space, they sleep in small cabins or in sleeping
Mnenie [13.5K]

Answer:

Free fall.

Explanation:

When astronauts sleep in space, they sleep in small cabins or in sleeping bags that are attached to the wall or ceiling of the station. Everything is weightless as there’s no gravity in space. So while sleeping there is a chance of floating around and bumping into things. Astronauts use sleeping bags that can be tethered to the wall or ceiling to solve this problem. Also the tethered sleeping bags provide a normal sleeping environment to the astronauts  as they can feel pressure on their back and head.  Their sleeping cabin is well ventilated as they can wake up with breathing trouble as a result of the inhalation of their own exhaled carbon dioxide which formed around their heads as a bubble. They use earplugs and a sleep mask to block the noise and light and can sleep vertically or horizontally. Compared to earth, sleeping is a bit different in space.

List and describe three factors that affect how quickly enzymes can work to catalyze reactions
Lilit [14]

Answer:

The correct answer is - temperature, pH, substrate concentration.

Explanation:

Various factors affect the rate of enzymatic reaction such as pH, temperature, substrate concentration, availability of activators or inhibitors in the reactions, and enzyme concentration.

Temperature: Temperature affects the rate of the enzyme-catalyzed reactions. Like most of the reactions with an increase in temperature rate of enzymatic reaction also rises up to a maximum level and then declines if the temperature continues to increase as enzyme denatures after a particular temperature.

pH: Similar to the temperature pH also increases the rate of reaction up to a maximum level and then declines the rate as every enzyme acts only at an optimum pH range.

Substrate concentration: If the substrate concentration is increased gradually while the concentration enzyme remains constant, the rate of reaction will increase until it reaches a maximum.

zhenek [66]

Answer: This mode of inheritance is known as Incomplete Dominance

Explanation:

Incomplete dominance occurs when a cross between two contrasting alleles (such as Type A and B) produces a heterozygous phenotype different from the two parents.

Thus, both Type A and B are dominant over Type O blood
