<em>Leaves fall from broken branches only if they were dry.Any others will not fall</em>
Answer:
A
Explanation:
Plants and trees couldn't thrive without capillary action. Capillary action helps bring water up into the roots. With the help of adhesion and cohesion, water can work it's way all the way up to the branches and leaves.
Farming is an agriculture practice, in which crops are harvested, cultivated, and yielded over a period of time. It can be of several types such as contour, terraces, nomadic, and sedentary farming.
<h3>What is Contour Farming?</h3>
Contour farming refers to the cultivation and growing of crops in sequential rows. The rows are level around the hill. Contour farming is found in hills and mountainous farmlands. The farming practice is common in European countries.
<h3>What is Terrace farming?</h3>
Terraces are the farming practice, in which the farmlands are formed by turning hills to form a ridged platform. Terraces are also found in the hilly regions are common in the countries China, Japan, and Southeast Asia.
Thus, contour and terraces farming is the type of agricultural practice done in the hilly and mountainous regions.

Answer: The genotype ratio of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant is 2TT:2Tt
The phenotype ratio is that all offsprings will be tall.
The genotype ratio of a cross between two heterozygous red flowers is 1RR:2Rr:2rr. The phenotype ratio is 3 Red flowers: 1 white flower.
Explanation: From the information given, tall is dominant and short is recessive while red is dominant and white is recessive.
Let T represent the allele for tall height, t represent the allele for short height, R represent allele for red flowers and r represent allele for white flowers.
The genotype of a homozygous tall plant is TT, the genotype of a heterozygous tall plant is Tt, the genotype of a heterozygous red flowered plant is Rr.
The possible genotypes of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant are TT and Tt.
Tt will manifest outwardly as tall because T is dominant over t. Therefore, all the offsprings will be tall.
The possible genotypes of a cross between two heterozygous red flowers are RR, Rr and rr. RR will manifest as red, Rr will also manifest as red because R is dominant to r while rr will manifest as white because white allele (r) is recessive. Therefore 3 plants will be red-flowered while 1 plant will be white flowered.
See the attached punnet squares for details of the cross.
