1.High yield modern agriculture refers to the practice of breeding genetically modified crops or using fertilizer to increase the production yield of planted crops. Two advantage of high yield modern agriculture are:
1. Production of large quantities of planted crops.
2. Ability to select and breed plants with superior qualities.
2. Agriculture have some negative influence on the environment, the major harmful environmental impacts of agriculture are:
a. Habitat loss: Agricultural practices present great danger to species and ecosystem. This is because, farmed areas serve as habitats for different types of wild plants and animals. Farming the areas makes these living organisms to lose their habitats and these throw the ecosystem into imbalance.
b. Soil erosion and degradation: When natural vegetation are converted into agricultural lands, the breaking up of the soil leads to erosion, which wash away the top soil and the nutrients that are embedded in it.
c. Pollution: The chemicals that are used during farming operations, such as fertilizers, pesticides, etc. cause pollution of the air and the surrounding waters.
3. Soil erosion is the process by which the top layers of soils are carried away by agents such as wind and water. The biggest negative effect of soil erosion is the loss of top soil. The top soil is the part of the soil that contain most of the nutrients that plants use to grow. When this part of the soil is lost, the soil usually becomes non fertile. Soil erosion can also lead to water pollution. When soils are eroded from the farm lands and carried to the surrounding waters, the waters will be polluted by the chemicals such as pesticides, herbicides and fertilizers, which are had been used on the soils. This can lead to the death of the animals that are living in the waters.
Answer:
the trait with Mendelian inheritance shows segregation in the F2 generation.
Explanation:
Blending inheritance is the theory that the offspring inherits any characteristic that are intermediate between those of the parents.
However, Gregor Johann Mendel showed that this not true that hereditary substances from parents merge together in their offspring.
In the given question,
the offspring of true-breeding parents show an intermediate phenotype, although a trait such as flower color in snapdragons is determined by two alleles with incomplete dominance.
The difference is that the trait with Mendelian inheritance shows segregation in the F2 generation.
El pulmón esta constituido por los lobulillos pulmonares que se continúan con los bronquiolos y bronquios intra pulmonares, también esta formado por el tejido conjuntivo que une lobulillos, vaso y bronquiolos. Lobulillos Pulmonares. Son pequeños sacos membranosos, pegados entre si y unidos por escaso tejido conectivo.
Answer:
IV, VI, III, I
Explanation:
Translation is the process of synthesis of protein from with the help of messenger RNA (mRNA).
The process of translation include initiation, elongation and termination.
- Initiation: In this step mRNA binds to ribososomes and tRNA, carrying start codon or methionine binds to mRNA.
- Elongation: In this step, the tRNA molecules carrying several amino acid bind to mRNA based on the sequence of mRNA codon and then moves (translocates) to the next mRNA codon which leads to amino acid chain.
- Termination: At the end, when a stop codon (UGA) identified, polypeptide is released.
So, the correct chronological order is IV, VI, III, I.
Organic matter in soil is called humus.
