The right option is; crust
The crust is the layer of Earth that is like the shell of an egg.
The crust is the hard outer shell layer of the earth that lies on top of the mantle. The earth’s crust is composed of different types of rocks which are; igneous, metamorphic, and sedimentary rocks. The crust is of two different types which are; (i) the continental crust (thicker and located under the land), and (ii) the oceanic crust (thinner and located under the ocean).
Answer: hope this helps
Explanation:
Aerobic bacteria use oxygen, which is added mechanically, to break down wastewater contaminants, converting it into energy. Bacteria use this energy to grow and reproduce. Anaerobic bacteria obtain oxygen from their food source. As anaerobic bacteria break down sludge, they produce methane gas. This methane gas can be used as an alternative energy source, called biogas, to fuel the wastewater treatment process.
The particular polymorphism normallyused for DNA fingerprinting is the Short Tandem Repeats (STRs) which are non-conding portions of DNA that consist of a repeating genetic sequence of DNA code.
Answer:
a) HT
Explanation:
This question shows an animal with two distinct unlinked genes i.e. on different chromosomes. One gene codes for head shape and the other for tail length. The gene for head shape possess alleles H and h, while gene for tail length possess alleles T and t.
According to Mendel's law of independent assortment, the alleles of a gene will separate into gametes independently of the alleles of another gene. This occurs in such a way that each gamete will contain only one allele from a gene.
Based on this principle, an animal with genotype HhTt will undergo meiosis and randomly produce gametes with the following allelic combinations: HT, Ht, hT, and ht. As seen in the gametes, only one allele of a gene occured in a gamete at a time.
Therefore, HT is the genotype possible in a gamete of parent: HhTt.
