Answer:
Type O
Explanation:
Type O is the most demanded blood type in hospitals, both because it’s the most common and because O-negative blood is a universal donor type, meaning it is compatible with any blood type. Conversely, type AB-positive blood is called the universal recipient type because a person who has it can receive blood of any type.
Peripheral nervous system. I hope this helped:)
Answer:
The model showing the condition must represent a recombination between the X and Y chromosome during meiosis in male.
Explanation:
In males, the sex chromosomes are X and Y, whereas, the females have XX chromosomes. When the X chromosome of males fuses with the female gamete it give rise to a female progeny.
The Sry gene is present on the Y chromosome. In some cases, the recombination between the X and Y chromosome during meiosis in males takes place and result in an X chromosome containing Sry gene. This Sry gene is responsible for the male characters and progeny carrying two X chromosomes, in which one has the Sry gene would have the male characters.
So, the in this case should represented the crossing over between the X and Y chromosomes in males and then passing of the Sry containing X chromosome to progeny.
1.To produce organisms with new traits, breeders can introduce mutations (usually in bacteria) using radiation or chemicals, or they can create polyploid plants. Polyploidy describes an organism with multiple sets of chromosomes.
2.An outline of the relationship between mutations and genetic variation. A mutation is known to be a natural process in which theDNA sequences is changed in a living organisms. Although, genetic variation is the change in both alleles and genes, both throughout and amongst the population.
3. Assuming the traits are recessive, and this is not a case of incomplete dominance, begin crossing any plants you have. Hopefully, you will have two heterozygous plants (for both traits) and will see at least one trait show recessive in one of the progeny. If you are lucky, you will get two plants, one recessive for red flowers, one recessive for short stems. Cross the two, and you will get a completely recessive individual.
Probably the availability of each kind of food is different from the other. So the half of the species that has more food available would outcompete the other half. Therefore, the correct answer is C. One half of the species will outcompete the other half of the species.
