Answer:
Cross each to a rabbit who you know is homozygous - i.e. a white rabbit. If there are any white offspring you know this is the heterozygote.
Explanation:
Heterozygous individuals are those with 2 different alleles of a gene. Homozygous individuals have have 2 alleles that are the same.
Imagine the allele for coat color is B black, or b white. If you cross 2 individuals who are homozygous for the black gene (BB), they would only produce black rabbits in the F1 (BB). If you cross the F1, they could only produce BB rabbits in the F2.
However, if you cross a heterozygous rabbit with a homozygous black rabbit (Bb x BB), you would get either BB or Bb rabbits in the F1. However, intercrossing them could produce BB, Bb, or bb rabbits. Therefore, white rabbits can be produced.
You know that white rabbits are bb. So if you are unsure about the genotype of the black rabbit, you can cross it with a white rabbit (either BB x bb or Bb x bb). If any white rabbits appear in the F1, you know there must be a b allele in the black rabbit genotype, so that rabbit must be heterozygous.
Cells are the smallest unit of life. This is true.
Cells are important to the structure and function of living things. This is true.
All organisms are made of multiple cells. This is false, because there are many single celled organisms like bacteria.
Cells come in different shapes and sizes. This is true, as there are cells with a variety of shape and size (round shaped cocci and the elongated and flat bacillus). There are cells from squid's nervous system, called the neurons, that are comparatively very large in size than the vast majority of the other cells.
Triacy because it seems like a long word
Answer:
proteins, because it helps in the regulatory function of the body.
Answer:
Play Therapy
Explanation:
Play therapy is a type of psychotherapeutic orientation by which play is used as a medium to help an individual, most especially children, to express their feelings. This therapy helps with the brain development of a child and enables a play therapist respond to the needs of a child, most especially the metal health needs.
Through play therapy, a child is naturally able to communicate his feelings as he is guided, and this helps children to become aware of themselves ad accept who they are.
