The answer is C. Polar covalent
I attached the right answers, maybe some words were difficult to understand:
Vagina in the sex of the female
The urethra is a duct which is shared between the urinary system and the testis. It is located into the penis (it passes both sperms and urine)
Testis means the testicles, where spermatozoids are produced.
Fallopian tube, join between the ovary and the uterus of the female, it looks like an elephant trunk
<span>Vas deferens: are the ducts between the testis and the prostate, it transports the spermatozoid and will be mixed with the prostatic secretion (sperm).</span>
Answer:
D
Explanation:
This involves a dihybrid inheritance I.e. two genes are being passed on. During meiosis, specifically, the Prophase stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) line side by side. According to the question, one chromosome contains A and B alleles and its homologue, received by the other parent carries a and b alleles. This means that the diploid individual has a genotype AaBb for that gene.
According to Mendel's law of independent assortment, the alleles separate independently of one another into gametes. I.e. allele A and a separates into the gametes without affecting alleles B and b of the other gene.
Crossing-over, which is the exchange of chromosomal segment occurs between the two homologues. Hence, the exchange of chromosomal segments containing alleles in the individual will possibly produce four gametes with the genotypes: AB, Ab, aB, ab.
Answer:
Living cells go through a series of stages known as the cell cycle. The cells grow, copy their chromosomes, and then divide to form new cells.
