Answer:
Advantage and disadvantage of asexual reproduction in plant is described below in details.
Explanation:
An advantage of asexual reproduction is that the resulting plant will approach adulthood quicker. Since the new plant is emerging from a grown-up plant or plant components, it will also be stronger than a seed. Asexual reproduction can take a spot by natural or manufactured (assisted by humans) means.
The significant disadvantages of asexual reproduction are the Shortage of diversity. Following the seeds are genetically the same as the parent they are more sensitive to the same diseases and nutrient insufficiencies as the parent. All the negative deviations endure for generations.

Name three sources of atmospheric carbon dioxide. (Write in complete sentences and be very detailed.)
This is science.
First and best answer gets 5 stars, a thanks, and a brainliest!
Doing this because I know I'm kickass at Chemistry.
One source would be human emissions. As humans, we use a lot of machines (like power plants) that produce large amounts of carbon dioxide into the atmosphere. The ocean also produces a lot of carbon dioxide via the evaporation cycle. Polluted waters eventually will go into the atmosphere. Volcanoes, even when not erupted, emit a lot of carbon dioxide as well. Dormant underground magma releases carbon dioxide through the Earth's pores, and even when a volcano erupts, it produces carbon dioxide as well.

Researchers stationed at different areas on a mountain and in a tunnel midway through the mountain boiled water at the same time. Even though the water at every station was at the same temperature, the pot at the top of the mountain started boiling before the others. Why?
Water boils when the vapor pressure is
the atmospheric pressure. The atmospheric pressure
at the top of the mountain.
Water boils when the vapour pressure is least the atmospheric pressure.
The atmospheric pressure is equal at the top of the mountain.
What is atmospheric pressure?The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth.
As we go up in altitude the air pressure becomes less. When the pressure decreases, it takes less energy to get the water molecules to escape the surface. So the temperature is less than it would be at sea level.
Air pressure is higher or greater at the bottom of a mountain. This is because the height of the air above that level is thicker than at the top.
Pressure is given by the equation, P=rho*g*h, where rho is the air density, g is the gravity value and h is the thickness of the air layer on top of the level where we are considering the pressure.
Therefore, as we can see, at the bottom of the mountain, the thickness h of air is greater, and so is the pressure.
Hence, water boils when the vapour pressure is least the atmospheric pressure and the atmospheric pressure is equal at the top of the mountain.

The prefix "semi-" means "partly". Based on your knowledge of the properties of elements, which kind of element is most likely used to make semiconductors?
liquids
metalloids
metals
nonmetals
Answer:
metalloids
Explanation:
The kind of element most likely used to make semiconductors are the metalloids.
These elements have properties between those of metals and non-metals in that they are not truly metals and are partly non-metals.
Under certain conditions they show features of metals or non - metals. The class of these elements are the metalloids. They are used to make semiconductors which are major components of electronics.Question

How is the rock in the deep mantle similar to the rock in the parts of the mantle nearest the surface? How is it different?
Answer:
Similarity: Rocks within the mantle contain more magnesium and iron than the ones in the crust.
Difference: Rocks in the deep mantle are under intense heat and pressure. In this case, they are semi-solid rocks that flow slowly. On the other hand, the part of the mantle that is nearest to the surface consists of rigid rocks. It has a lower temperature than the rocks in the deep mantle.
Explanation:
Rocks within the mantle contain more magnesium and iron than the ones in the crust.
What is Rocks?
Rocks in the deep mantle are under intense heat and pressure. In this case, they are semi-solid rocks that flow slowly.
On the other hand, the part of the mantle that is nearest to the surface consists of rigid rocks. It has a lower temperature than the rocks in the deep mantle.
According to geologists, a rock is a naturally occurring material made up of crystalline crystals of various minerals that have fused together to form a solid mass.
Therefore, Rocks within the mantle contain more magnesium and iron than the ones in the crust.

You have a stock solution of HNO3 with a concentration of 4.5 x 10^-4 M. However, you need 275 ml of a 2.50 x 10^-5 M solution. How much of the stock solution will you need?
Answer:
15.28 mL
Explanation:
From the question given above, the following data were obtained:
Molarity of stock solution (M₁) = 4.5x10¯⁴ M
Volume of diluted solution (V₂) = 275 mL
Molarity of diluted solution (M₂) = 2.5×10¯⁵ M
Volume of stock solution (V₁) needed =.?
The volume of the stock solution needed can be obtained by using the dilution formula as illustrated below:
M₁V₁ = M₂V₂
4.5x10¯⁴ × V₁ = 2.5×10¯⁵ × 275
4.5x10¯⁴ × V₁ = 0.006875
Divide both side by 4.5x10¯⁴
V₁ = 0.006875 / 4.5x10¯⁴
V₁ = 15.28 mL
Therefore, the volume of the stock solution needed is 15.28 mL

What is the percent composition of Phosphorus in Li3PO3
Answer:
you will get 17.983 g of lithium for every 100 g of lithium phosphate.
Explanation:
69.7% is the percent by mass of Lithium in Li[tex]_3[/tex]PO[tex]_3[/tex]. A percent is obtained by multiplying the result by 100.
One approach to show the concentration for an element within a compound or component in a combination is as a mass percentage. The mass percentage is computed by dividing the total weight of the combination by the mass of each component and multiplying the result by 100%. The mass percent is calculated by dividing the mass that contains the compound and solute by the mass for the element or solute.
99.795g/mol = molar mass of Li[tex]_3[/tex]PO[tex]_3[/tex]
6.94g/mol = molar mass of Li
mass percentage of Li=(molar mass of Li/molar mass of Li[tex]_3[/tex]PO[tex]_3[/tex])× 100
=(6.94/99.7)× 100
=69.7%
