An allele that can only be expressed when no dominant allele is present
<span>In order to understand trans fat, you must understand the prefix. Trans and cis are prefixes that mean opposite and same side, just like transgender people identify with a gender that is not in line with their biological sex, and cisgender people identify with their biological gender. Cis fat describes the fatty acids attached to the glycerol in triglycerides. Cis fats have hydrogen attached to the carbon chain just like trans fats, but at one, two, or more places on the chain, two hydrogen atoms attached on the same side, and the fatty acid chain gets bent, making the collection of fats less dense and therefore healthier for you and I. Trans fats have hydrogen atoms on alternating sides all the way down the chain, making them denser and solid at room temperature. In order to turn a plant oil (cis fat) into trans fat, the cis fat has to be blasted with hydrogen in order to turn the fatty acid chains from cis to trans. This adds more energy to the fats while also making them denser, which turns olive oil into a butter-like substance.</span><span />

Hope I could help!!
Answer:
9:3:3:1
Explanation:
If two parents for a dihybrid cross are fully heterozygous for two genes, the phenotype ratio comes 9:3:3:1. Here, the alleles of both genes should exhibit complete dominance-recessiveness. This means that one allele of a gene should be able to mask the expression of its another allele. Similarly, alleles of one gene genes should assort in a random manner during anaphase-I irrespective of the assortment of alleles of another gene.
Under these conditions, each parent produces four types of gametes in equal proportion. And the random fusion of these gametes gives progeny in 9:3:3:1 phenotype ratio.
For example, a dihybrid cross between TtRr and TtRr would produce progeny in the following phenotype ratio=
9 tall and red: 3 tall and white: 3 dwarf and red: 1 dwarf and white
Here the allele T gives "tallness" while the allele "t" gives "dwarfism". The dominant allele "R" gives "red flowers" while the recessive allele "r" gives white flowers.
Answer:
Sustainable use of the environment
Explanation:
Be it the ecosystem or the food you eat, if you just take up whatever you need instead of over exploiting the resources, another life can benefit from it. The relationship we need to form with our environment should be mutualism or commensalism but not parasitism.
