Answer:

A new type of plant, when introduced in an environment, can have an adverse effect on the other native plants present in the environment. These new plants can have a high reproduction rate and grow aggressively reducing the space and nutrients for the native plants.

Reduction in space and nutrient for native plants reduce the population of native plants and reduction in native plants can dis balance the ecosystem of that region because most of the wildlife is dependable on native plants.

For example water hyacinth an invasive species when introduced in water bodies grows very fast and covers the entire surface of the water body which results in oxygen depletion in the water.

This oxygen depletion kills native species of plants and fishes and disturbs the balance of the environment.

The plant could become an invasive species and drive species that were present before to extinction.
For example, certain species of vines can wrap around and suffocate other plants, driving them to death.
Hope this helps!

A quantity of a gas has an absolute pressure of 400 kPa and an absolute temperature of 110 degrees kelvin. When the temperature

VMariaS [17]

Answer: The new pressure of the gas is (A) 854.46 kPa.

The pressure of a given mass of gas at the absolute temperature 110 degrees K is 400 kPa.

The temperature is raised to 235 degrees K with constant volume.

Therefore,

Initial pressure $P_{1}=400kPa$

Initial temperature $T_{1}=110K$

Final temperature $T_{2}=235K$

Final pressure $P_{2}=?$

According to pressure law of gas,

$\frac{P_{1} }{T_{1} }=\frac{P_{2} }{T_{2} }$ ( at constant volume) $P_{2}=\frac{P_{1}T_{2} }{T_{1} }$

$P_{2}=\frac{400X235}{110}$

$P_{2}=854.46kPa$

Thus, the required new pressure of the gas is 854.46 kPa.

How many atp molecules are added to get glycolysis started

romanna [79]

Answer:

2 ATP

Explanation:

2 ATP is required to get the glycolysis started. The glycolysis process is divided into two parts, the first part is called the preparatory phase in which energy is required and the second part is called the payoff phase in which energy is produced.

During the first phase in the first step during the conversion of glucose to glucose six phosphate one ATP is consumed and in the third step during the conversion of fructose 6 phosphate to fructose 1,6 biphosphate one more ATP is consumed and in the second phase, 4 ATP is produced.

Therefore the net gain is 2 ATP because 2 ATP are added to get glycolysis started.

If the nucleus of a cell was removed the cell wouldn’t be able to make proteins because

jasenka [17]

The nucleus contains the cells DNA(genetic material) which is basically the recipe for making proteins. mRNA is first transcribed off of DNA and then in translated(by ribosomes) to polypeptides(proteins).

Which features do most stratovolcanoes and cinder cone volcanoes have in common?

Sergeu [11.5K]

Answer:

Option (2)

Explanation:

Strato-volcanoes are the steep, conical shaped, formed by the alternative beds of ash and lava. The magma in this type of volcano contains high silica content and are comprised of bubbles. When the gases are released from these bubbles, then a greater force is exerted from the bottom towards the surface. Due to this, they are very explosive and ejects a huge amount of materials during eruption. For example, Mount St. Helens .

Cinder cones are the simplest volcanoes with steep sides. They are made of the materials and semi solidified lava that are ejected from the vents of the volcano. Eruptions are often explosive due to the force exerted by the gas and the molten lava and are accumulated near the vent. For example, Paricutin.

<u>These two types of volcanoes are similar in terms of its eruption that is violent and explosive in nature. In addition to that, they both have steep sides. </u>

Hence, the correct answer is option (2).
