Answer:
Father’s phenotype non roller Father’s genotype rr
Mother’s phenotype roller Mother’s genotype Rr
Probability of this couple having a child who is a tongue roller : 1/2
Explanation:
Given that allele for rolling (R) is dominant over allele for non rolling (r).
Since father is a non roller his genotype would be rr
Mother is a heterozygous tongue roller so her genotype would be Rr
Their progeny:
Rr X rr :
R r
r Rr rr
r Rr rr
Half of the offspring have Rr genotype which will make them tongue roller so probability of this couple having a child who is a tongue roller is 1/2.

The name for this type of energy is potential energy

It is called this because it has the potential to do work. Objects that are in

Answer:
The kidneys remove wastes and excess water from the blood to produce urine. Urine passes from the kidneys to the bladder via two narrow tubes called ureters. To discharge waste when the bladder is full, a person urinates through the urethra.
Explanation:
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:
Some mutations don't have any noticeable effect on the phenotype of an organism.
Explanation:
This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.
