Answer: Option B
Explanation:
Desert farming is the practice of developing agriculture in deserts. Agriculture can be defined as the act of irrigation, water supply and farming.
The desert farming is different from the other types of farming and it has been practiced by the person living there.
These practices are to be used very precisely as the water is not available in a plenty amount. Taking into consideration drip irrigation is used in the desert and dry areas.
Drip irrigation can be defined as the modern method by which the micro-irrigation technique in which the water and the nutrients are saved and it allows the water to drip slowly into the roots of plants.
I think the correct answer among the choices listed above is the first option. In an ecosystem without primary consumers, t<span>he populations of producers would increase. This is because nothing will eat the the producers or the plants. The plants will only grow and increase.</span>
If we name the gene for pods with A, than the alleles are: A-dominant, a-recessive.
The possible genotypes for the smooth pods are: Aa and AA, while genotype for constricted pods is aa.
If one parent has constricted pods and the other parent is homozygous for smooth pods there are two possible combinations:
P: AA x aa
F1: Aa Aa Aa Aa all of the offspring are constricted
Another combination:
P: Aa x aa
F1: Aa Aa aa aa half of the offspring are with constricted pods and half with smooth pods.
So, the correct answers are:
• all of the offspring will have constricted pods
• 50% of the offspring will have constricted pods and 50% will have smooth pods.
