Answer:
A.
Powders have more surface area and will dissolve faster.
Explanation:
please mark this answer as brainlest
The solute-like solids can dissolve in the solvent through the dissolution process. Powders have more surface area that permits more dissolution.
What is surface area?The surface area is the amount of space covered or occupied by an object. It is directly dependent on the solubility and increases with an increase in the solubility.
The surface area of the powder is more compared to the solid pill and hence, the solubility of the scoop of powder is more than the pill.
Therefore, powder dissolves faster because option A. has more surface area.

In an ecosystem, if the last three animals of a species are all females, the species will become extinct because it takes a male and a female to reproduce .
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Last week, scientists released incredible images of aurora australis, known as the northern lights, as seen from the Hubble telescope. The Hubble telescope was placed in orbit in 1990 by the space shuttle and has since delivered the sharpest images we have of our planet, our galaxy, and the universe. The images delivered last week show the beautiful display of lights in the southern hemisphere. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn.
Which statement in the news passage above is inaccurate?
The aurora australis cannot be seen from space.
The Hubble telescope does not orbit our planet.

Answer:water erodes the earth by passing over rock and thinngs many times, as in a river, the water slowly washes away the rock turning it into sediment or silt.
Explanation:
Answer:Hope this helps :) if so pleas could you mark brainliest:) enjoy!
Explanation:
The cycle of water erosion has been here since forever thanks to the rain rivers, ponds lakes, the sea and the ocean because it first starts off with the rain then the rain fills up the lakes and pond and start rivers and the rivers lead to the sea and ocean and from there the water evaperates then it rains again and the lakes and ponds help with the evaporation.

Answer the following questions with a picture only PLEASEEEEE.
1. What is the main source of energy for ecosystems?
2. What are some natural things that can disturb ecosystems?
Answer:
1.Photosynthesis is the process of converting light into energy
2.Natural events, such as wind, drought, flood, fire, or disease.
Explanation:
1.Since photosynthesis converts light into C-H bonds in organic material, photosynthesis is the most common source of energy in most habitats, and therefore carbon flow and destiny are inextricably related to energy flow.
2.Natural disasters such as wind, drought, storm, burning, or disease may cause disruption. These "natural occurrences" are often linked to human activities. Air and water emissions, as well as climate change effects such as temperature, rainfall, and ocean chemistry, are also examples of human disruptions.

Write a paragraph on why food needs to be digested. :)
Please hurry I need it.
Answer: You die if no digest
Explanation:
Food needs to be digested because your body can't contain large stuff whole, so it has to be converted into a smaller amount. For Instance, if you were to eat a entire turkey then your body would just explode I guess if you wouldn't digest it. Also, without digesting food you can't enter new food into your body. Therefore, this is why food needs to be digested.

In the electromagnetic spectrum, the headings which best describe the chart are X: FM, Y: AM.
What is electromagnetic spectrum?The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.
