I suppose it's a zygote. In haplontic life cycle haploid gametes fuse together creating the zygote (diploid) that promptly divides meiotically creating 4 haplontic cells serving as spores.
Depending on what trait the alleles carry, the brothers will have a different phenotype and a different genotype.
For example; Eye color. My sister is heterozygous, meaning she has brown eyes. I am homozygous recessive, meaning I have blue(green/hazel) eyes. We both have the same parents, I just happened to inherit both of the recessive eye color alleles from my parents whereas, my sister inherited both the dominant and recessive alleles.
So, since the brothers inherited different sets of alleles, their genotype for a certain trait will be different.
Answer:
No atoms are created or destroyed in chemical reactions.
Explanation:
Matter cannot be created or destroyed. When two reactants contact each other, a chemical reaction occurs which breaks the bonds between atoms and rearranges them, forming new bonds which transform them into the product. The same amount of atoms exists before and after the reaction.
Our sleep cycles typically last usually 90 to 110 minutes on average.
The nitrogen cycle is completed with the process of Denitrification
<h3><u>
Explanation:</u></h3>
Denitrification finishes the nitrogen cycle by transforming nitrate behind to vaporous nitrogen. Denitrifying bacteria are the doers of this method. These bacteria utilize nitrate alternately of oxygen while gaining energy, delivering nitrogen gas into the environment.
Denitrification relies on microbial action to crumble freely nitrogen-containing components. Bacilli absorb nitrate to generate energy, but in the method, denitrification transpires and nitrogen is diminished. Denitrification is an anaerobic means, transpiring chiefly in soils and deposits and anoxic zones in ponds and shores.
