Answer:
Tilling breaks the natural structure of the ground by exposing the organic matter, accelerates mineralization, and pollutes.
Explanation:
Organic matter, together with porosity and humidity directly influence in the recovery of the soil structure and stability when these are exposed to different mechanical treatments or actions. Porosity and soil matrix continuity directly influence in the hydraulic conductivity and interchange water and air processes.
Tilling systems affect the productivity of the crops, and the physic, chemical and hydraulic characteristics of the soil. Tilling modifies the superficial layer of soil, alters the continuity of porosity and reduces the amount of organic matter in the ground.
Intensive use of tilling contributes severely to the carbon emission. Carbon is stored in the soil and when this last one is altered by tilling, carbon is exposed and released out in the open, becoming CO². This gas is one of the gases of the greenhouse effect and one of the causes of global warming.
Intense tilling breaks the natural structure of the ground by exposes the organic matter, it accelerates mineralization, and it pollutes.
Abrasion, plucking, deposition, and physical weathering are the glacial actions which can be observed all over the park.
Explanation:
When the huge ice masses slope down to fall over the land surface during a glacier, many glacial actions or processes take place which defines the landforms formed on the surface. These actions include abrasion, plucking, deposition, and physical weathering.
Abrasion is an erosive process which scrapes the surface of ice rocks and other frozen rocky material beneath the ice and causes striations over the rocks.
Plucking also an erosive process plucks the frozen rocks beneath the ice surface.
Physical or freeze-thaw weathering causes water to enter the cracks in the rocks when the temperature increases. This water enters inside and freezes inside when the temperature goes down. This repeated melting and freezing of water destabilizes the rocks and will break the rocks.
These materials which are worn off are transported and deposition on the land surface when the glacier settle down.
Longshore drifts occur along coastlines and brings materials along the coast when waves move at an angle with the coastline.
Answer:
The correct answer is B make cells produce a functional CFTR protein.
Explanation:
Cystic fibrosis is a disease that is caused due to the mutation in the transmembrane protein known as cystic fibrosis trans membrane conductance regulator or CFTR. Cystic fibrosis trans membrane regulator proteins helps in the formation of thin mucus and due to the mutation in CFTR the mucus becomes thick.The disease cystic fibrosis basically affect the respiratory system.
If gene therapy is used to treat cystic fibrosis then it can replace the mutated CFTR gene with a functional one so that the cell containing CFTR gene can produce functional CFTR protein.
Answer:
Tyr Ile Leu Ala Thr Thr
Explanation:
In a DNA sequence, a pair of three bases form a codon that codes one particular amino acid in the protein. Proteins are consist of 20 amino acids and these amino acids are coded by a pair of three bases.
There are four bases in a DNA - Thymine (T), Adenine(A), Guanine(G) and Cytosine(C).
The given mutated DNA sequence will also code for some amino acid, that is as follows:
TAC - Tyr (Tyrosine)
ATC - Ile (Isoleucine)
TTG - Leu (Leucine)
GCG - Ala (Alanine)
ACG - Thr (Threonine)
ACT - Thr (Threonine)
Thus, The mutated DNA sequence TAC ATC TTG GCG ACG ACT codes for Tyr Ile Leu Ala Thr Thr.
