3. In 1981, a stray black cat with unusual curled-back ears was adopted by a family in California. Suppose you were the person who owned the first "curl" cat, and wanted to develop it into its own breed. How would you determine whether the allele for curled ears is dominant or recessive? Why does it make a difference for breeders whether an allele for a trait is dominant or recessive?
It is possible to determine whether the allele for curled ears is dominant or recessive by performing a test cross. It is fundamental for breeders because desired traits show differential patterns of inheritance.
In a diploid (2n) organism, a given gene locus exhibit two different variants or forms called 'alleles'.
An individual is homo-zygous when both alleles for a given gene locus are the same, while an individual is heterozygous when alleles are different.
In cases of complete dominance, the expression of the recessive allele is completely masked in heterozygous individuals.
A breeder is a professional who performs genetic crosses between different organisms in order to obtain offspring (eg., plants, animals, etc) with desired phenotypic features.
A test cross is a type of cross that breeders use to determine whether an allele is dominant or recessive (in this case, the allele for curled ears).
In a test cross, the organism that is a carrier of the unidentified allele is crossed with another organism that is believed to be homo-zygous for the recessive trait, and then the proportion of offspring is examined.

Viruses can not grow in nutrient media. Why ?
Answer:
Viruses are obligate intracellular parasites and cannot grow on inanimate media. They need living cells for replication, which can be provided by inoculation in live animals among other methods used to culture viruses (cell culture or inoculation of embryonated eggs).
what is the chemical composition of earth's core?
Answer: metal—specifically, iron and nickel.
Explanation: Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal—specifically, iron and nickel. The shorthand used for the core's iron-nickel alloys is simply the elements' chemical symbols—NiFe.

what organisms undergo cellular respiration
Answer:
Cellular respiration takes place in the cells of fungi, animals, and plants.
Explanation:
Notice how these things are all living things. Cellular respiration is the process of turning glucose into ATP. This ATP is used for cellular functions and also to break down more glucose for more ATP. It is kind of like a circular process.

describe the mechanism of blood sugar regulation (20 marks)
Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.
The pancreas releases glucagon when glucose levels fall too low. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream. High BG levels stimulate the release of insulin. Insulin allows glucose to be taken up and used by insulin-dependent tissues, such as muscle cells.p

What statement about the inheritance of mitochondrial DNA is true?
A) The sperm cell donates most of the material in the cytoplasm to the zygote, including mitochondrial DNA.
B) The egg and sperm cells contribute equal amounts of mitochondrial DNA to the zygote.
C) The egg cell donates most of the material in the cytoplasm to the zygote, including mitochondrial DNA.
D) The sperm cell donates most of the DNA in the nucleus to the zygote, including mitochondrial DNA.
Answer:
The answer should be C
Explanation:
The egg contributes all the cytoplasm and organelles to the zygote. The sperm only contributes one set of chromosomes.
The typical sperm midpiece contains approximately 50-75 mitochondria with one copy of mtDNA in each. This represents an 8- to 10-fold decline in copy number during spermiogenesis.
