Red blood cells carry oxygen; white blood cells fight disease.
<span>The question says, vertebrates have notochord during early embryonic development. The statement is true. A notochord is a cartilaginous skeletal rod which support the body in all embryonic and some chordate animals. It has essential role in vertebrate development. It is a primitive beginning of the spinal cord.</span><span />
Hello There!
It contains dissolved substances, cells and cell fragments.
The other parts of blood are:
Red blood cells - Carry blood around the body
White blood bells - Fight against bacteria and diseases
Platelets - Small fragments of bells. They are involved in forming blood clots.
Hope This Helps You!
Good Luck :)

Answer:
e. The statement is true for meiosis I only.
Explanation:
When we talk about homologous chromosomes, we talk about two chromosomes forming a pair of genes. One comes from the mother, and one comes from the father in sexual reproduction.
The random segregation of chromosomes is what we call the result of crossing over during meiosis I, and is what generates genetically unique individuals in each reproduction.
The genotype for the F1 generation is PURPLE PETALS.
In cross breeding, the offspring of the original generation in a cross are called F1 generation. When two breeding of a particular living organisms are crossed, then the F1 generation will be all the same.<span />
