What was the control in Redi's experiment?
Why is there so much biodiversity on Earth? Provide at least two examples
Answer:
climate and agriculture
Explanation:
for example the coconuts of the pacific warm water islands are far different than the crab apples of the north or how the heat of the south means for less clothes while the brisk of the north requires more layers.
Explanation:
There are several key reasons for high biodervisity in tropical ecosystems. High NPP directly contributes to a diversity by supporting more species with minimum viable populations of each organism increase overall mutation frequency and hence intraspecific genetic varation.

Two equal strips A and B were from a potato whose cell was 30% of sugar. The strip
A was placed in a solution of 10% sugar concentration while B was placed in 50%
sugar concentration
a) What change was expected in strip A and B
b) Account for the change in strip A
Answer:
Movement occurs from higher concentration to lower concentration.
Explanation:
Strip A cell has 30% of sugar which is placed in a solution of 10% sugar so the sugar that is present in the potato strip A moves from inside to the outside due to the process of osmosis while on the other hand, if strip B was placed in 50% of sugar solution so the sugar moves inside from outside environment through semi-permeable membrane. This movement occurs due to difference in concentration of both environments i.e. cell and solution.
Two equal strips A and B were from a potato whose cell was 30% of sugar. strip A was placed in a solution of 10% sugar concentration while B was placed in 50% sugar concentration
a) strip become flaccid and strip B will swell
b) hypotonic solution causes movement of water to diffuse out of cell
Simple diffusionSalts and sugars in solution will diffuse away from areas of high concentration into the surrounding solution
Water also diffuses away from areas of high free water concentration into areas of more solute concentration.here in strip A is placed in low sugar solution that causes movement or diffusion of water from the cell to the solution as it is only 10% sugar concentrationin strip B which is placed in low sugar solution that is placed in high sugar concentration solution that is 50% which means there will be movement of water from solution into the cells of the strip which cause them to swellThus, Two equal strips A and B were from a potato whose cell was 30% of sugar. strip A was placed in a solution of 10% sugar concentration while B was placed in 50% sugar concentration
a) strip become flaccid and strip B will swell
b) hypotonic solution causes movement of water to diffuse out of cell

Which would best allow a species to survive environmental changes? O A small population VE O B genetic diversity C. similar physical features 0 D. Iow mutation rate
Answer:
B
Explanation:
The situation that would best allow a species to survive environmental changes is genetic diversity. Thus, the correct option is B.
What is Species?Species may be defined as a group of organisms that can reproduce with one another in nature and produce fertile offspring. It is one of the major components behind the occurrence of speciation.
Genetic diversity may be characterized as the sum total of all the variations that are significantly found in the genetic makeup of individuals within a particular species.
Genetic diversity allows some individuals of the same species to adapt and survive better in the changing environmental conditions.
This is also favored by natural selection by accomplishing the favorable variation to those individuals and permits them to express those beneficial traits to their offspring.
Therefore, genetic diversity is responsible for the survival of any species in changing environmental conditions.

What device is used to measure water forming on the glacial ice sheet?
The device that is used to measure water forming on the glacial ice sheet is known as the Airborne Topographic Mapper (ATM).
What do you mean by Glacial Ice sheets?Glacial ice sheets may be defined as a mass or accumulation of glacial ice of more than 50,000 square kilometers. This sheet significantly contains about 99% of the freshwater on Earth and is sometimes called continental glaciers.
According to the context of this question, an instrument known as the Airborne Topographic Mapper (ATM) considerably collects the elevation of the ice surface along with its thickness. Apart from this, it also measures the formation of ice from water on the glacial ice sheet.
Therefore, the Airborne Topographic Mapper (ATM) is a device that is used to measure water forming on the glacial ice sheet.

Options are:
A. geotropism
B. transpiration
C. phototropism
D. photosynthesis
The correct answer is c.
Explanation:
Phototropism is known as a natural and organic movement of a plant towards the light. This is due to the natural ability of a plant to change direction based on changes in lighting in the environment. But external stimulus is not enough. It must generate some changes inside the plant that make it react in this way: hormones. A hormone is a chemical substance produced in one tissue and transported to another, in which it exerts one or more highly specific effects.Auxins are members of a group of plant hormones that are more beneficial to stimulate plant growth, it is the responsible mechanism of the response to phototropism in plants, which tends to be concentrated in the region of the stem and leaves, when a plant lacks this, it can be noted since the bending towards the light source is little or no, that is, auxins make the cells of the stem growth region (rhizomes and stems) lengthen.
How would this food web be affected by the extinction of the Osprey?
Answer:
The fish would grow in the population, because osprey mainly eat fish.
Because of the fish growth, the ocean, pond, or whatever, makes the water have less oxygen. The fish eat small fish, crustaceans, worms and almost anything that is not poisonous to them. These populations will decrease.
Because there are no Ospreys, the raccoons will get hungry too, as they sometimes eat Osprey eggs.

Answer:
"Manganese is a grey-white, hard and very brittle metal.
It tarnished on exposure to air and oxidized to manganese when heated."
Credits to: Yahoo
Answer:
Manganese is a pinkish-gray, chemically active element. It is a hard metal and is very brittle. It is hard to melt, but easily oxidized. Manganese is reactive when pure, and as a powder it will burn in oxygen, it reacts with water (it rusts like iron) and dissolves in dilute acids.

Explain why or why not you think so using evidence from the simulation
Answer:
I don't think so
Explanation:
An excessive amount of greenhouse gases cause the earth's temperature to rise and contribute to climate change. I didn’t do the simulation but too many greenhouse gases are bad for the environment. They raise the temperature of the earth instead of maintaining it.
