Answer:
Bacteria
Explanation:
Bacteria constitutes large group of unicellular organisms that lacks membrane bound organelles and constitute cell wall. Bacteria are used for the production of recombinant proteins.
Bacteria can be selected easily for the recombinant protein formation. The plasmid of bacteria is helpful for the integration of desired genes and the production of protein. The bacteria culture can be maintained easily in the laboratory. The different strains of bacteria with different traits can be used for the production of different recombinant proteins at low cost.
Thus, the correct answer is option (1).
9: Well big groups of birds are often found competing for food, causing fights and even death due to the fight. If a flock of birds from population A goes to population B, there would be more competition due to birds wanting food and nesting places that are good.
10: Many species evolve to suit environmental changes, but let's say this change in the environment was bad. Pollution, species of aggressive animals, which would eat the food the animals need and cause a downgrade in food leaving the area bare, and hunting, which would bring humans to the area and cause them to camp out, eat the animals and wild vegetables, such, can cause negative population changes. Due to these things birds could get sick and die off, causing population to go down. If trash and sewage are not cleaned up it could affect the birds food source and cause it to be bad for a long time, the aggressive animals would kill and eat the birds causing a continuous spiral of death, and hunting could cause them to die.
Answer:
What I expect would happen: First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.
Explanation:
The water cycle is the process where water falls as rain, is transported via rivers and streams to lakes and oceans, evaporates into the sky, condenses into clouds, and falls as rain again. Here's a diagram:
water.usgs.gov
water.usgs.gov
So what would happen if there were no condensation stage?
The condensation stage is the one where water vapour gathers together into clouds (and when the clouds become heavy enough with vapour, release water as rain). So the first answer is that there would be no clouds.
Without clouds, I foresee a few things happening:
From clouds come rain. With no clouds, there would be no rain.
Clouds move moisture from lakes and oceans (where it evaporates up) to mountains and other places inland that spark rainfall. And so vast stretches of land would become desert.
Clouds reflect sunlight and help cool the Earth. With no clouds, the average temperature of the Earth would increase significantly.
And so to summarize what I expect would happen. First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.

Answer:
Calcium is a silvery-white, soft metal that tarnishes rapidly in air and reacts with water. Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys. Calcium is essential to all living things, particularly for the growth of healthy teeth and bones. Calcium phosphate is the main component of bone. The average human contains about 1 kilogram of calcium.
Explanation:
People who are lactose intolerant are unable to digest lactose, the sugar commonly found in dairy, because their bodies don't make the enzyme lactase.
Lactase works by breaking down lactose into a simpler sugar that can be used by the body. Without it, lactose is not absorbed by the body & remains in the waste where gut bacteria metabolize it & cause the bloating, gas & other similar discomforts experienced by the lactose intolerant.
Hope that helps!
In truth, though, it is the non-lactose intolerant people that are the mutants. Not the other way around. Most wild animals don't consume milk after they have been weaned & it's just something humans developed to accommodate their diet.
