Answer:
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents
Answer: Which biotechnology could we use to help alleviate that problem and produce more honey bees? So far no one has come up with a fix. But now scientists are on the case — and some of their possible solutions sound pretty wild.
Explanation:
Answer:
Explanation:
The mass of the substance is determined by subtracting the first reading from the second. A container holding the substance of interest is placed on the balance and weighed. This is the first reading. The substance to be used is removed from the container and the container weighed again.
Answer:
- Diploid → Prophase, metaphase, and anaphase
- Haploid → Telophase
Explanation:
During prophase I, chromosomes get condensed. Each of the chromosomes gets in pair with its homologous one. They do so to make the crossing-over possible, a stage where they interchange their parts → 2n
During metaphase I, each of the homologous pairs is driven to the equatorial plane, where they randomly line up → 2n
During anaphase I, occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair → 2n
In telophase I, half of the chromosomes are already in one of the poles, while the other half is on the other pole. Each group of chromosomes has now half the number of the original cell. The nuclear membrane forms again in each pole → n
Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.
The two new cells are ready for meiosis II.
<h2>Question:-</h2><h3> Which structure is found in all animal cells?</h3>
<h2>Answer :- Centrioles </h2>
<h2>Explanation:- </h2>
- They are barrel shaped cell organelles only found in animal cell
- There function is to help in division of cell membrane by forming microtubules which help in division of chromosomes ( spindle fibres)
- They play role in arranging microtubules which act as endoskeleton of the cell
- They also help in formation of cell structure like cilia and filaments
