The hypothesis is; Increasing the concentration of fertilizer will lead to an increase in plant growth.

The variables to be tested are; concentration of fertilizer and plant growth.

A hypothesis is a speculative claim or explanation put forth based on scant data and used as a springboard for additional research or trial. It is an educated guess or testable prediction regarding the correlation between two variables or phenomena.

By manipulating the concentration of fertilizer as the independent variable and measuring the resulting plant growth as the dependent variable, we can test the hypothesis and determine if there is a correlation between fertilizer concentration and plant growth.

It is pertinent to understand that few things need to be considered in this process. The huge metallic vessel needs warming alongside legitimate guidelines of temperature for powerful heat need of the container(organism) in the first place. Simultaneously it is additionally appropriate to chill off the substance of the vessel and justified the cooling limit. Kindly note that it is temperature is additionally related to the encompassing pressing factor and diminished temperature is a characteristic of lower pressure, which can be considered surrounding pressure (one or lower than 1 air pressure).

SO;

Specific gravity = 1

mass of water = 135 kg which is equivalent to 135 liters

To \(cm^2\); we have:

1 liter = 100 \(cm^2\)

5 liter = 292 \(cm^2\)

∴

135 L will yield 2631.616 \(cm^2\)

However, converting this into MegaJoules

Recall that:

cal/\(cm^2\) = 1 calorie or 4.19 Joules

4.19 Joules = 4.19 × 10⁻⁶ MegaJoules

Hence;

2631.616 \(cm^2\) = (2631.616 ×  4.19 × 10⁻⁶) Mega Joules

= 0.0110264878

= 11026.47 × 10⁻⁶ Mega Joules per day

Cell Membrane = the semi-permeable structure that surrounds the cell and keeps all of the cells organelles from exploding everywhere.

Cell Wall = the rigid 'armor' of the cell that surrounds it after the membrane. Usually made up of cellulose and ONLY found in plant cells.

Nucleus = A really dense organelle of the cell usually surrounded by two membranes. They contain and protect your genetic material. Basically everything that makes you, you.

He could determine whether the hypothesis is based on repeated experiments.

Explanation:

A theory is a hypothesis that has been proven correct by many expirements.

Francis could design and perform a new controlled experiment to test the hypothesis to determine whether it is a theory. Therefore, the correct statement is option D.

A hypothesis is a scientific explanation for a phenomenon that is based on prior observation. However, a theory is a well-supported and widely accepted explanation for a natural phenomenon that has been tested and based on scientific fact.

A hypothesis has the potential to become a theory if tested through carefully designed and controlled experiments by collecting data needed for the experiment.

If the results of an experiment conducted by Francis are consistent with the hypothesis, the information can be used to develop a theory that can be used to explain a broader range of phenomena. However, if the results are not by the hypothesis, Francis cannot consider the hypothesis as a theory that must be supported by evidence.

Therefore, Francis needs to design and perform a new controlled experiment to test the hypothesis to determine whether it is a theory.

Answer:

to retain moisture and hold the soil in place.

Explanation:

this technology of putting dead plants on the soil under the plants and the area nearing the plants is called mulching.it is helpful in reducing the rate of evaporation and also reduces soil erosion.

Conservation plowing is achieved to minimise soil erosion. Thus, option C is correct.

Soil erosion is the deterioration of the topmost layer of soil. The top fertile layer of the soil withers leaving the soil infertile.

It is a gradual naturally occurring phenomenon but can be accelerated with human interventions.

There are many factors responsible for soil erosion:

• Deforestation

• Excessive grazing

• Mining

• Construction work

• Drought and floods

Soil erosion negatively affects the crop yield and also clogs the water bodies. This is therefore harmful for the aquatic species. Dry and barren soil is more prone to floods.

Soil erosion should be minimized as it produces a negative impact on the ecosystem.

Soil erosion can be prevented by planting more number of trees. The roots of the trees help in holding the soil in its place.

Therefore, soil erosion should be checked to preserve the soil fertility.

The genotype of the F1 offspring is YyTt, and the phenotype is yellow and tall. The probability of each phenotype in the F1 offspring is as follows yellow and tall is 1/2 or 50%, green and short is 1/2 or 50%.

Genotype refers to the genetic makeup or combination of alleles present in an organism, while phenotype refers to the observable traits or characteristics expressed by an organism. Genotype represents the genes an organism carries, while phenotype represents the physical or observable features resulting from the interaction between genotype and the environment.

When a heterozygous ail yellow plant (genotype Yy) is crossed with a homozygous short green plant (genotype tt), the F1 offspring will have the genotype YyTt and the phenotype of yellow and tall.
