Answer:
To prepare a proper seed bed.
Hope this helps!
Answer: to mix and aerate soil, remove weeds, and in general create the perfect seedbed for many plants with less physical labor than using a manual tool like a spade.
meaning: aerate
introduce air into (a material)
Food webs are unable to cross from one environment into another (e.g., from land to water).
TRUE
FALSE
Answer: false, for example, if a frog eats flies, and the flies are land animals, if they go extinct the frogs could die off, meaning any fish or water dwellers that eat the frogs can starve and cause a large chain reaction.

If you have a transfer RNA molecule with the anticodon AAG what is the amino acid being carried in during elongation?
Answer:
The correct answer would be - Phenylalanine
Explanation:
The amino acid is formed during the process of translation that requires mRNA and tRNA sequences to make a three-base sequence code of amino acid which is complementary to the mRNA sequence triplet code.
mRNA sequences are complementary to the DNA sequence and tRNA sequences but tRNA sequences called anticodons and they have uracil instead of thymine which makes them different from DNA.
So, anticodon is - AAG
mRNA would be - UUC, (DNA would be - AAG)
then triplet code UUC is code for Phenylalanine amino acid.

Which weathering process uses a solvent to wear things down
A. Freezing ice
B. plants and animals
C. Moving air
D. Moving water **
I picked D. I need this answer quick!!!! Will give brainliest
Moving water is the weathering process uses a solvent to wear things down. So, the correct option is D.
What is Weathering?Rocks, soils, minerals, wood, and manmade materials all deteriorate due to weathering when they come into touch with water, air gases, and living things.
The natural dissolution of rocks and/or minerals found on the Earth's surface is known as weathering. To disintegrate rocks that are located on the surface, weathering is essential. Moreover, chemical weathering alters the molecular make-up of rocks and/or soils.
Even the most substantial of the boulders are being broken up into smaller pieces by the sun, rain, frost, and wind before they are hauled away. Weathering is the name given to this process.
Thus, the correct option is D.

How would different climate zones be impacted by climate change?
Answer:
Changes in Earth's climate have different effects in different areas of the world. Some places will warm much more than others, some regions will receive more rainfall, while others are exposed to more frequent droughts. Regional changes in temperature and precipitation are having impacts on people and ecosystems.
Answer:
A new global warming study predicts that many current climate zones will vanish entirely by the year 2100, replaced by climates unknown in today's world. ... Novel climates appear throughout the tropics and subtropics, while the climates now found in tropical mountain ranges and near the poles may vanish

Although they often live in the same habitat, the American toad breeds earlier in the spring than the Fowler's toad does.
What can be inferred from this information?
a
The American toad will cause the extinction of the Fowler's toad.
b
The two species interbreed throughout the spring season.
c
The two species do not interbreed because of geographic isolation.
d
The two species do not interbreed because of temporal isolation.
The two species do not interbreed because of temporal isolation.
What is temporal isolation?Temporal isolation, in biology, a type of reproductive isolation mechanism among organisms in which the differences in the timing of critical reproductive events prevent members of closely related species, which could otherwise breed with one another, from mating and producing hybrid offspring.
The American toad breeds earlier in the spring than the Fowler's toad does. Therefore, they do not interbreed, even though they often live in the same habitat.

on-site soil quality and crop productivity?
Healthy soils produce healthy crops that in turn nourish people and animals. Soils supply the essential nutrients, water, oxygen and root support that our food-producing plants need to grow and flourish. They also serve as a buffer to protect delicate plant roots from drastic fluctuations in temperature.
What are molecules and how are they used in running? Evidence
What is homeostasis and how does homeostasis work to maintain internal stability? Evidence
Answer:
Osmosis helps cells maintain homeostasis because a cell needs to maintain a specific water balance so that chemical reactions can take place. Osmosis can also be used to balance out the concentration of other molecules (such as sugar or salt) present on either side of a cell membrane.
Explanation:
Homeostasis is the ability of a system to regulate its internal environment through maintaining a stable, relatively constant set of properties such as temperature and PH. Key Terms homeostasis : The ability of a system or living organism to adjust its internal environment to maintain a stable equilibrium, such as the ability of warm-blooded.

1.Which way does water tend to flow in a hypertonic environment?
2.In which type of environment does a cell experience Equilibrium?
3.When would a cell have the most Turgor Pressure?
4. In a hypertonic environment, where is the concentration gradient?
5.What is the name of diffusion that is specific to water?
(ILL GIVE BRAINLY TO FIRST PERSON)
Answer:
1. The hypertonic solution has a lower water concentration than the hypotonic solution, so a concentration gradient of water now exists across the membrane. Water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic.
2. I am not sure
3. Generally, turgor pressure is caused by the osmotic flow of water and occurs in plants, fungi, and bacteria. ... In plants, this entails the water moving from the low concentration solute outside the cell, into the cell's vacuole.
4. The hypertonic solution has a lower water concentration than the hypotonic solution, so a concentration gradient of water now exists across the membrane. Water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic.

In your own words, explain how a radiosonde can be used to predict future weather conditions in a location.
Answer:A radiosonde measures and collects various data such as, pressure, altitude, geographical position (latitude/longitude), temperature, relative humidity, wind (both wind speed and wind direction), cosmic ray readings at high altitude, and many other things. You can then analyze all this data and combine it to see what the weather conditions will be possibly be like.

What does the law of conservation of energy state?
It is important to use as little energy as possible.
Organisms save the energy that they create.
Organisms change energy into mass.
Energy cannot be created or destroyed
Answer:
Energy cannot be created or destroyed
Explanation:
Similarly, the law of conservation of energy states that the amount of energy is neither created nor destroyed. For example, when you roll a toy car down a ramp and it hits a wall, the energy is transferred from kinetic energy to potential energy.
