Compare and contrast properties of sister chromatids and homologous chromosomes. drag the appropriate items to their respective bin.

The primary stage is prophase. The nucleolus vanishes and the two centrosomes start to frame the mitotic spindle. The axle extends between two inverse shafts f the cell. Next is the metaphase. The centromeres of the chromatid sets adjust at the focal point of the thematic axle.

At that point anaphase, the centromeres will part that isolates the chromatid combine. They are presently called chromosomes. The last stage is the telophase. The chromosomes will at that point frame a string like chromatin and for throb envelope, a nucleolus shows up.

•Sister Chromatids consists of identical nucleotide sequences former to crossing over, segregate in the anaphase of mitosis, separate during anaphase II of meiosis.

•Homologous Chromosomes-present in a pair, one is of maternal origin, the other of paternal origin, and crossover between them contributes to genetic diversity, separate during anaphase I of meiosis.

Further Explanation:

When the chromosomes exist in pairs and each member of the pair has a specific length, centromere location, gene arrangement, and banding pattern, then the pair of chromosomes are referred to as homologous chromosomes. Homologous chromosomes are those who share some common characteristics like the length of the chromosome, the position of the centromere, the location of genes, and the banding pattern. Based on the centromere position, the chromosome can be to the following types:

Basically, homologous chromosomes are a pair of chromosomes, whereas sister chromatids are formed by the process of replication of a single chromosome. The genetic makeup of two sister chromatids is the same. The Haploid (n) number of chromosomes is half of the diploid chromosome. During gamete formation, every single cell produced contains a haploid set of chromosomes.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
