which of the following statements best describes the major difference between metaphase 1 of meiosis and metaphase of mitosis? (a) in metaphase 1 tetard srts of homologous chromosomes stay together as they line up along the center of the cell (b) in metaphase homologous chromosomes sre separated as each sister chromatid set os pulled to one end of the cell (c) im metaphase sister chromatids are separated and pulled apart to form a total of four new haploid cells. (d) in metaphase 1 sets of sister chromatids line up at the center of the cell and spindle fibers pull them apart.
The statement that best describes the major difference between metaphase 1 of meiosis and metaphase of mitosis is as follows:
In metaphase 1, tetrad sets of homologous chromosomes stay together as they line up along the center of the cell.Thus, the correct option is A.
What is Mitosis?Mitosis may be defined as a type of cell division through which a parental cell produces two genetically identical daughter cells which are usually diploid in nature.
In the metaphase of mitosis, the chromosomes usually line up in one plane and form an equatorial plane. The chromosomes are attached to the spindle through the centromere.
While in the metaphase of meiosis I, the bivalents are arranged on the equatorial plane and the centromeres of each chromosome divide longitudinally.
Therefore, the correct option for this question is A.

Which sentence describes an example of sublimation
Asexual reproduction in the parent cell will result in offspring with
A) similar genetic information.
B) half the genetic information.
C) double the genetic information.
D) four times the genetic information.
Correct answer: A). Similar genetic information.
Asexual reproduction is a mode of reproduction, which involves one parent and gives offspring that are genetically similar to each other and to their parents. It does not involve the fusion of male and female gamete.
It allows the plant to reproduce quickly, as a result of that the parent plant is compete-ting with their offspring for the same nutrient, sunlight, and space.
Example: Binary fission, fragmentation, vegetative propagation.
to meet cellular needs for food,water,energy,waste removal,multicellular organisms have developed various specializations,such as organs,and organ systems.
Answer:
The correct answer will be- true and structural specializations
Explanation:
The evolution of life on earth has suggested that life has moved from the simplicity to complexity or from single-celled organism to multicellular organism.
This multi-cellularity is achieved through the property of called cellular differentiation and specialization. as the cellular complexity increases, therefore, cellular demands like the use of energy, food, water and other variables increased.
This lead to the formation of the organ and organs system specializes to perform specific functions like the digestive system and another biological system.
Thus, true and structural specializations are the correct answer.
Answer: the answer is Structural
