What is an economic region?
an economic region is a district or an administrative division of a city or territory that is designed according to some material distributive or productive criteria.
Discussion of departmentalization?
Departmentalization is the division of the work load by allocating tasks to specific departments. This means that a department that manufactures a product has nothing to do with ordering the material to make the product.
What is velour material?
Velour material is material used to make tracksuits etc.
How does the material of the asthenosphere differ from the material of the lithoshere?
the material in the astehnosphere can flow slowly and the lithosphere flows on top of the astenosphere HOPE I HELPED!!
Can Raw materials be direct or indirect?
raw material are indirect material
What is the process whereby genetic material is exchanged between homologous chromosomes during synopsis of the first meiotic division?
The process is called genetic recombination or crossing over. It involves the exchange of genetic material between homologous chromosomes, resulting in the formation of new combinations of alleles. This increases genetic diversity among the offspring.
What type of material is exchanged during cross-over?
During crossover, genetic material is exchanged between homologous chromosomes. This process is essential for genetic variation and occurs during meiosis when homologous chromosomes pair up and exchange segments of DNA through a process called crossing over.
What are chromosomes that have the same length and carry genes for the same traits?
Homologous chromosomes are chromosomes that have the same length and carry genes for the same traits. One homologous chromosome is inherited from each parent. During meiosis, homologous chromosomes pair up, allowing for genetic material to be exchanged between them.
Could crossing over occur during second meiotic division?
No, crossing over occurs during the first meiotic division when homologous chromosomes exchange genetic material. In the second meiotic division, the chromatids of each chromosome separate, resulting in the formation of haploid daughter cells.
Is there crossing over in mitosis?
No, crossing over does not occur in mitosis. It is a process that happens during meiosis, where genetic material is exchanged between homologous chromosomes. Mitosis is a type of cell division that results in two identical daughter cells.
What is a result if a species have homologous chromosomes?
If a species has homologous chromosomes, it means that they have pairs of chromosomes with similar genes in the same order. This can facilitate genetic diversity through processes like crossing over during meiosis. Homologous chromosomes are essential for genetic variation and proper segregation of genetic material during cell division.
What type of material is exchanged during crossing over?
During crossing over, genetic material in the form of DNA segments are exchanged between homologous chromosomes. This process can result in the creation of novel combinations of genes, contributing to genetic diversity in offspring.
How many homologous chromosomes interact with each other or dont during mitosis and meiosis?
In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1. In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1.
Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation?
Crossing over during meiosis results in the exchange of genetic material between homologous chromosomes, creating new combinations of alleles. During the first division of meiosis, duplicated homologous chromosomes are separated, resulting in the formation of haploid cells with unique genetic content due to the random assortment of chromosomes.
What will happen to the cell as it undergoes prophase 1?
In prophase I the homologous chromosomes pair and form tetrads, during which crossing over occurs and genetic material is exchanged between the homologous chromosomes. Refer to the related link for an animated illustration.
What are the chromosomes that are paired one from each parent called?
The chromosomes that are paired, one from each parent, are called homologous chromosomes. These chromosomes carry genes for the same traits and are similar in size and shape. During meiosis, homologous chromosomes exchange genetic material through crossing over.
How do homologous chromosomes contribute to genetic diversity through the process of crossing over?
Homologous chromosomes contribute to genetic diversity through crossing over, a process where sections of DNA are exchanged between paired chromosomes during meiosis. This exchange results in new combinations of genetic material being passed on to offspring, increasing genetic variation.
