The vast majority of a tree's carbon comes from the air, which averages 0.03-0.04% by volume (300-400 ppmv) CO2. This is fixed through photosynthesis and eventually stored as glucose which the plant can then use for its metabolism.
Answer:
1. HETEROzygous - Having 2 diff.alleles for a gene
2. Dominant - Allele whose trait is always expressed
3.Recessive - Allele whose trait is hidden unless paired.......
4. genotype - the genetic makeup of an individual
5.phenotype - the physical charact.of a trait
6.honozygous - having 2 identical alleles for a gene
Answer:
Microarray technology is a very useful technology that allows to study the measure the expression levels of large numbers of genes simultaneously. It consists of a solid support (that can be glass, silice, or nylon), and to it are attached a lot of single stranded DNA fragments that acts like probes. By complementarity, the genes corresponding to this probes that are being expressed at some time will attach to it. Probe-target hybridization is usually detected and quantified by detection of a fluorophore compund, a silver stained, or chemiluminescence-labeled targets.
True... Everything needs energy.
The correct answers are:
3) the nuclei of most euk cells contain chromosomes found in homologous pairs - diploid. one member from mother, one from father. At meiosis, one of two members segregates into daughter nucleus. Gametes have one set of chrms - haploid.
4) during formation of haploid cells, diff types (nonhomologous) chrms segregate independently from eachother
Chromosomes are structures that represent the genetic material of an organism and consist of DNA and proteins packed together.
The chromosome theory of inheritance claims that :
Chromosomes are organized in homologous pairs, one member from the mother and one from the father. During the meiosis (formation of gametes) the members of a homologous pair separate, each gamete receives one member which is selected randomly. The members of different chromosome pairs (nonhomologous) are sorted into gametes independently of one another in meiosis.
The chromosome theory explains the behavior of chromosomes during meiosis and helps understanding why genes are inherited according to Mendel’s laws.
