Answer:
Halting the use of resources is impractical. Increasing the mining efforts would lead to further depletion of resources. Hence, the correct options are: build dams, use cars that emit fewer harmful gases, and halt the runoff of factory waste into rivers and streams which would positively affect Earth's resources.
Explanation:
first step
A copy is made of one side of the DNA segment where a particular gene is located. This copy is transferred to the cytoplasm.
second step?
This mirror like copy of a DNA segment is called messenger RNA (mRNA)
third step?
Each group of three bases on the mRNA segment codes for one amino acid.
fourth step?
The mRNA segment is fed through the ribosome.
fifth step?
Molecules of transfer RNA (tRNA) deliver amino acids from the cytoplasm to the ribosome.
sixth step?
The amino acids are dropped off at the ribosome.
seventh step?
The amino acids are joined to make a protein. Usually, one protein is produced for each gene.
Answer:
C. Water will move into the cell through osmosis. The salt and water concentrations will become similar inside and outside the cell.
Explanation:
Osmosis is the movement of water from its higher concentration to the lower concentration through a semi permeable membrane. Here, the cell have higher salt concentration and lower water concentration as compared to its outside. Since cell membrane is semi permeable, salt cannot pass through it. So, water will move into the cell through osmosis to equalize the salt and water concentration on either side of cell membrane.
Given:
Time: 3.5 hrs
Velocity: 120 miles/hour
Now Distance= Speed x Time
Now Velocity and Speed have the same magnitude. Velocity being a vector quantity has a definite direction. Where as speed is a scalar quantity, it indicates only the magnitude and doesn’t define any direction.
Hence Distance= Velocity x Time
Distance= 3.5x20=420 miles
Answer:
Taproot systems feature a single, thick primary root, called the taproot, with smaller secondary roots growing out from the sides. The taproot may penetrate as many as 60 meters (almost 200 feet) below the ground surface. It can plumb very deep water sources and store a lot of food to help the plant survive drought and other environmental extremes. The taproot also anchors the plant very securely in the ground.
Fibrous root systems have many small branching roots, called fibrous roots, but no large primary root. The huge number of threadlike roots increases the surface area for absorption of water and minerals, but fibrous roots anchor the plant less securely
