An organelle is a cellular structure which performs specific functions within a cell. Organelles are important to the cell as cells would not be able to function without them: even the most common organelle - the nucleus. A cell without a nucleus cannot function (except prokaryotes, as they have an undefined nucleus)
A and C are the same and thus both wrong. B. The higher the temperature, the more molecules start moving, the more space inbetween them and thus the larger.
Meiosis is invovled in the production of gametos (sex cells) so that the plant can reproduce. This usually happens during the time the plant is flowering
I think you mean Round could be RR or Rr (round is dominant to wrinkled)
R=round
r=wrinkled
RR would be round phenotypically
Rr would be round phenotypically
To determine if they are RR or Rr you should perform a backcross with a wrinkled mutant!
I put a picture to demonstrate this.
If they are RR then if you cross with rr you would only get phenotypically Round pea plants.
If they are Rr then if you cross with rr you would get 50% round and 50% wrinkled. Any wrinkled? Definitely the heterozygote Rr!!
Answer:
In metaphase 1, chromosomes from the mother and father line up randomly along the middle of the cell.
Explanation:
In diploid (2n) organisms, the homologous chromosomes are the two copies of each chromosome, where one of these homologs is the chromosome from the mother, while the second one is from the father. During metaphase I, the homologous pairs of chromosomes pair together at the middle of the cell. The law of independent assortment, also known as or Mendel's Second Law, states that homologous chromosomes line up in random orientations at the metaphase plate during this period (metaphase I).
