Answer:
That will Be Positive and negative
Explanation:
The two hydrogen atoms and one oxygen atom within water molecule (H2O) form polar covalent bonds. While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water's properties of attraction
hope that help, cheers :D.
Answer:
The scientist would be an ecologist i.e. an expert in ecology.
Explanation:
The scenario in question investigates the affect of a biotic factor (beaver population) on various abiotic factors such as water flow and soil nutrient content.
In this context, ecology is the scientific study of interactions between biotic and abiotic components of an ecosystem.
Environmental science can help us figure out how we interact with the earth, and how to deal with environmental problems.
Answer:
Law of Independent assortment
Explanation:
Gregor Mendel, who was regarded the father of Genetics, discovered principles that governs inheritance in his experiments. He discovered that the alleles of a gene will separate into gametes when he performed a crossed involving a single gene or character like height, pea color etc. He proposed his law of segregation based on this.
However, he considered two characters or genes in his cross, which he called a DIHYBRID cross. He discovered that the alleles of each different gene separates into gametes independently of one another i.e. without one gene influencing the other in each gamete. He called this principle his LAW OF INDEPENDENT ASSORTMENT.
He obtained a 9:3:3:1 phenotypic ratio for the F2 dihybrid offsprings which is only possible if each gamete equally likely contains two alleles of the two different genes in different combinations.
