Answer:
a. lack of running water
Explanation:
The Tippy tap technology was invented to solve the issue of running water problem. This technology is designed mainly for hand washing and it is used in the rural area to solve the running water problem.
This technology technique needs only forty milliliters of water; it is less expensive and reduces the chance of transmitting diseases as the user only touches a bar of soap suspended by a string.
Answer:
16/64 = 1/4
Explanation:
This is a typical trihybrid cross involving three genes T, P and Y. A plant with genotype TTPpYy is crossed with a plant recessive for all traits (ttppyy).
According to Mendel's law of independent assortment, each allele for each gene will get sorted into the following 8 gametes with only 4 different: TPY, TPy, TpY, Tpy, TPY, TPy, TpY and Tpy.
The recessive parent, ttppyy will produce tpy, tpy, tpy, tpy, tpy, tpy, tpy and tpy.
Hence, using a punnet square, 64 offsprings will be produced with only 16 of them heterozygous dominant for the three traits with genotype (TtPpYy). Hence, proportion is 16/64 equivalent to 1/4.
Answer:
The false statement is e. It is found only in gram-negative bacteria.
Explanation:
Drug resistance is a condition that is usually developed in bacteria because of the wrong use of medicines. This condition can cause a mutation and can be transferred with horizontal gene exchange, that does not require breed and it can happen between two grown bacteria. As it happens in all species of bacteria, therefore it's not only found in gram-negatives.
