The correct answer is C; Weathering is the breaking down of rock and erosion is the movement of the smaller pieces.
Q1. The answer is egg.
The fertilisation is a fusion of two gamete cells which results in the formation of the zygote. Sperms and eggs are gamete cells, male and female, respectively. After a sperm and an egg fuse, i.e. the fertilisation takes place, a zygote is created and then begins a development of an embryo.
Q31. The answer is 100% chance
Alleles:
T - the dominant allele for the tongue rolling
t - the recessive allele
Genotypes and phenotypes:
TT - people able to roll tongue
Tt - people able to roll tongue
tt - people not able to roll tongue
<span>The mother’s genotype is TT and the father’s genotype is TT. The offspring will get T allele from the mother and T allele from the father:
Parents: TT x TT
Offspring: TT TT TT TT
So, all of the offspring will have genotype TT and will be able to roll their tongues.
Q32. The answer is codominant.
A codominance is a pattern of inheritance in which both alleles of a gene are expressed. So, there are no dominant and recessive alleles and both will affect the phenotype. For example, plants with alleles for both red and white flowers will have flowers that are both red and white.</span>
Answer:
the sequence of three bases that codes for a specific amino acid
The main function of DNA polymerase is to make DNA from nucleotides, the building blocks of DNA.
Asking a question is the first part of the scientific process (followed by research, hypothesis, experiment, data/analysis and conclusion). A question that can be answered using the scientific process must have some answers, must be able to be tested or tried through an experiment and must lead to a supposition or proposed explanation that is verified.
