Correct Answer: A. 50%

Explanation

Dominant alleles are referred to with capital letters, so let's call the dominant blue-petal allele B. Recessive alleles are referred to using lower case letters, so we will call the recessive white-petal allele b. A heterozygous organism has one dominant and one recessive allele, so the heterozygous flower has one B allele and one b allele. Its genotype is Bb. Because B is dominant to b, its phenotype (the trait produced by its genotype) is blue petals. A homozygous organism has two of the same allele. The homozygous flower will either have two BB alleles or two bb alleles. The question states that the flower with white petals is homozygous recessive, so its genotype is bb and its phenotype is white petals. The only genotype that produces a white phenotype is bb, because you need two recessive alleles in order to express the recessive trait. When you cross the two flowers, each parent donates one of its two alleles for petal color to the offspring. Accounting for every possible combination of alleles from each parent, there are four possible outcomes from a cross between Bb and bb: Bb, Bb, bb, and bb. (It may also help to draw a punnet square to visualize the four possible combinations). As you can see, these outcomes lead to two possible genotypes: Bb and bb. The Bb genotype produces flowers with blue petals, and the bb genotype leads to flowers with white petals. Because two of the four possible outcomes are genotype bb, two of the four possible outcomes are for flowers with white petals. Two out of four is equal to 50%, so 50% is the correct answer.

Agricultural finance is the act of acquisition and use of capital in agriculture. It deals with the supply and demand for funds in the agricultural sector of the economy while agricultural credit is a repayable loan given to farmers with or without interest to enable them carry out their farm operation more efficiently.

(b) Sources of agricultural credit available to the small-scale farmer are: (i) Agricultural Banks like Nigerian Agricultural and Cooperative Bank (N.A.C.B.). (ii) Supervised Agricultural credit schemes. (iii) Thrift and saving societies. (iv) Self financing or personal savings.(v) Money lender. (iv) Cooperatives societies. (c) Six problems associated with Agricultural credits are: (i) High interest rate. (ii) Lack of collateral security. (iii) Diversion of loan by .borrowers. (iv) Long gestation periods, especially for plantation crops (v) High incidence of loan defaulters. (vi) Difficulties in recovering loan

Correct Answer: A) Onhcocerciasis

Explanation

Immunization is a process where a person is given a vaccine to help the body build immunity against a particular disease. The question is asking which of these diseases cannot be prevented by immunization. The options are Onchocerciasis, Poliomyelitis, Cholera, and Tuberculosis. Onchocerciasis, which is also known as river blindness, is caused by a parasitic worm that is transmitted through the bites of infected blackflies. There is currently no vaccine available to prevent Onchocerciasis, so Option A is the correct answer. Poliomyelitis, also known as polio, is a highly infectious viral disease that can cause paralysis. The polio vaccine has been very effective in preventing the disease, so Option B is not the correct answer. Cholera is a bacterial disease that can cause severe diarrhea and dehydration. There is a vaccine available to prevent cholera, so Option C is not the correct answer. Tuberculosis, commonly known as TB, is a bacterial infection that affects the lungs. There is a vaccine called the BCG vaccine that can help prevent TB, although it is not always effective. Therefore, Option D is not the correct answer. In summary, the disease that cannot be prevented by immunization is Onchocerciasis, so Option A is the correct answer.

Correct Answer: C. good governance
