lord [1]

Answer:

TYPE OF LIQUID SUBSTANCE RECEIVED

Explanation:

The independent variable in an experiment is the variable that the experimenter deliberately changes or manipulates in order to bring about a response in the dependent variable/measured variable.

In this experiment, the TYPE OF LIQUID was changed for each group of plant in order to see how it affects how the plants grew. Hence, the TYPE OF LIQUID is the independent variable while the dependent variable is the plant growth, which is dependent on the independent variable.

An individual that is heterozygous for flower color and for height (PpTt) is test crossed. What is the phenotypic ratio of the o
MrRa [10]

Answer:

9:3:3:1

Explanation:

This type of crossing that involves two characters is referred to as dihybrid crossing. Generally, when there is a dihybrid crossing for heterozygous genes for both parents, the phenotypic ratio is usually 9:3:3:1 as shown in the figure in the attached document below.

Assuming the colour is White (P) and Black (p) and the

Height is Tall (T) and short (t)

The possible phenotypes will be in the ration

9 - White and Tall

3 - White and short

3 - Black and Tall

1 - Black and short

It should be noted that phenotypic ratio (phenotype) describes the outward appearance (what can be see physically) and not the genetic make-up. Thus, where there is a dominant character like P or T, the recessive characters are not considered to have been expressed.

Kai has a see-through glass tank with air, plants, and animals that eat those plants. He sealed the tank so no material can get
kipiarov [429]

Answer:

1. Carbon is moving from the living things in the tank into the air when they respirate, and from the air back into plants via photosynthesis

2. The amount of carbon in living things is increasing as plants use the carbon in the atmosphere, and animals eat the plants.

Explanation:

According to the question, a well sealed tank contains air, plants and animals. Since light can get into the tank, plants can perform photosynthesis. Living things in the tank release carbon in form of carbondioxide (CO2) gas through respiration. Plants then make use of this carbondioxide (CO2) to synthesize carbon-containing food (glucose) in the presence of sunlight. This process is called PHOTOSYNTHESIS.

Animals eat those plants and the stored carbon in the plants gets transferred to them. The animals release this carbon into the air again in the form of carbondioxide when they respire. Hence, carbon in the tank moves from the living things (respiration) into the air and back into plants (photosynthesis).

2. Since the amount of carbon in the air is decreasing, the carbon is being used by the living things in the tank. Plants absorb the carbon in the atmosphere for photosynthesis, then animals eat the plants to get the carbon. Therefore, the amount of carbon in the living things is increasing.
