What role do producers play in the water cycle? Plants need water to grow and maintain their structure. They absorb groundwater, that is, water collected below ground level due to percolation of rain water, through their root system

Plants need water to grow and maintain their structure. They absorb groundwater, that is, water collected below ground level due to percolation of rainwater, through their root system.

Transpiration is another important part of the water cycle. Transpiration is the process of water vapor being released from plants and soil. Plants release water vapor through microscopic pores called stomata.

There are four main stages in the water cycle. They are evaporation, condensation, precipitation, and collection. Let's look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice, and soils to rise into the air and turn into water vapor (gas).

The portion of the cell cycle when the cell is growing and does not contain a replicated genome is referred to as Growth 1 (G1) phase.

The cell cycle refers to the process from which a cell is born until it dies, which involves interphase and a mitotic phase.

The interphase can be in turn divided into a Growth 1 (G1) phase, ad synthesis (S) phase, and a Growth 2

The S phase is the specific period where the DNA is duplicated (DNA replication) during the cell cycle.

Answer: the answers are 1. They are vestigial structures that once performed... 2. imprints of leaves or footprints... 3. homo erectus... 4. the early stages of embryo... 5. a close evolutionary connection between humans and many other mammals

Explanation: 100% correct as of april 2022

Human embryo have many characters that disappear during their growth. Tail bone is vestigial in humans, they have hair and produce milk indicates that these are mammal.

Mammals are the animals that have some unique feature like giving birth to young once, have mammary gland, having body hair, etc.

The appearance of tail in mammals just like fish, amphibians shows evolution.

Humans have hair and mammary gland which produce milk to nourish the young means they belongs to mammals.

Thus, all these characteristics shows the evidences of evolution.

What is matter?

~ Matter is something which all physical objects are believed to be made of -- it is a material substance that occupies space, possesses mass, and is made up mostly of atoms (basic unit of matter) which consists protons, neutrons, and electrons, that constitutes the observable universe.

~ State of matter is the distinction or the difference in forms of matter we can observe in our daily life. The 5 states of matter thus far are; solid, liquid, gas, plasma, and bose-einstein condensate.

Matters differ in characteristics, appearance and compositions. Written here are the basic differences in 3 most fundamental states of matter.

Solid - a matter which composed of rigid and closely packed particles -- particles move only via vibrations. Has definite shape and definite volume.

Liquid - particles can move back and forth, not too tightly packed -- has definite volume but with no definite shape.

Gas - the particles in gas are relatively far apart compared to solid and liquid, they're moving fast back and forth/side to side, and bouncing nonstop. Gas neither have definite shape nor volume, and is way compressible than solid and liquid.

Answer: Increased interest in public transportation

Explanation: got it right

Due to public transportation, more vehicles need more petroleum, leading to an increase in petroleum prices, hence option a is correct.

Petroleum prices are likely to have risen as a result of both increased demand and worries about supply interruptions. Global demand for oil has been rising, exceeding any increases in supply and surplus capacity.

One major reason is that developing countries, particularly China and India, have been quickly rising. These economies have grown more industrialized and urbanized, contributing to an increase in global demand for oil.

This is because transportation costs will rise, raising the prices of numerous commodities. This is cost-push inflation, as opposed to inflation produced by increased aggregate demand excess growth.

Therefore increased interest in public transportation, leads to rising petroleum prices, hence option a is correct.

In bacterial cell division, the cell divides into two nearly equal halves. This process is referred to as mitosis.

To answer the question, we need to know what cell division is

This is the process in which parent cells divide into two or more daughter cells.

There are two types of cell division namely

Mitosis is the process in which non-reproductive (somatic) parent cells divide into two daughter cells that have the same number of chromosomes as the parent cell.

Meiosis is the process in which reproductive parent cells divide into four daughter cells with half the chromosoes of the parent cells.

From this, we see that cell division in which the cell divides into two nearly equal halves is refered to as mitosis.

So, in bacterial cell division, the cell divides into two nearly equal halves. This process is referred to as mitosis.
