The seven levels of classification are Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Answer:
Soil erosion.
Explanation:
No-till plowing can be defined as a farming method or technique which typically involves planting crops (seedlings) without tilling the soil rather the farmer would only open a narrow or very shallow trench of sufficient depth and width to cover up the seedlings. Thus, the no-till plowing makes crop residues to be left on the soil and by extension preventing soil erosion through the absorption of water by the crop residues.
Hence, by leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent soil erosion.
Additionally, the water retention ability of no-till plowing is usually a boon to farmers because it slows down evaporation and serves as a good protection for drought-stricken environments.
Answer:
B
Explanation:
Prokaryotic cells lack a nucleus
Answer:
The correct answer is - each macromolecule has its own function and role in the body of an organism.
Explanation:
There are four major macromolecules that are essential for the energy and growth and development of an organism, are Proteins, carbohydrates, fat and nucleic acids. Each macromolecule is essential and found in various food sources so any specific macromolecule can not found in a healthy diet.
Proteins play various roles in the body such as support, building blocks, carriers, enzymes, and hormones. On other hand, carbohydrate provides energy for the cells, the transmission of the genetic information will be transferred by a nucleic acid. Fat also helps provide insulation, make lipid membranes.
<h3><u>Answer;</u></h3>
Coelom
Animals with 3 issue layers may be characterized by the presence or absence of a <u>Coelom</u>.
<h3><u>Explanation</u>;</h3>
- Animals may be characterized by the presence of a coelom, formation of the mouth, and type of cell cleavage during embryonic development.
- Diploblasts contain two germ layers that is the inner endoderm and outer ectoderm, while triploblasts contain three germ layers, that is; endoderm, mesoderm, and ectoderm.
- <em><u>Triploblasts can be further categorized into those without a coelom called acoelomates, those with a true coelom called eucoelomates, and those with “false” coeloms known as pseudocoelomates.</u></em>
