In an experiment, three plants of the same species were grown in each of six identical pots. The heights of the plants were measured when growth began. Each post was watered everyday with salt solutions of different concentrations. The data for the experiment are shown on the table
1.) state the effect of increasing the percent of salt in the solution used to water the plants on the average final height of the plants in groups A through D
2.) state one way diffusion was involved in the cause of death of the plants in groups E and F.
Answers
Answer:
See the answer below
Explanation:
1. The data from the experiment shows that as the percentage of salt in the solution used to water the plants increased, the growth rate of the plants decreased. As the percentage increased from A to D, the change between the average initial and the final heights decreased, meaning that an increase in the percentage of the salt in the solution used to water the plants had a negative impact on the growth rates of the plants.
2. Due to the solutions used to water the plants in groups E and F being more concentrated (hypertonic) to that of the cell sap of the plant, water molecules diffused out of the cell sap to the ambient solution. As time goes by, the plants lose too much water, become wilted, and died off eventually. Instead of water molecules to keep diffusing into the plants in order for them to grow, the reverse was occurring and this led to their death.

Maria visited the mountains in Wyoming and became interested in the different ways that mountains and valleys form. How do mountains and valleys develop from a series of normal faults?
A. A footwall slips down to form a valley at a converging plate boundary. Rock on either side of the valley becomes the mountains.
B. Walls of rock grind past each other in opposite directions. This pushes one side up above the other to form the mountains.
C. Compression causes rock to fold and bend, but not break, in the middle of a plate. The rock that folds upward becomes a series of mountains.
D. A hanging wall slips down at a diverging plate boundary. The slab of crust that falls forms a valley, and the slabs on each side form mountains.

Which two factors are used to calculate the kinetic energy of an object?
gravity and velocity
O velocity and mass
O mass and volume
O volume and height
Answers
Answer:
velocity and mass are the two factors.
Velocity and mass are two factors that are used to calculate the kinetic energy of an object. Therefore, option B is correct.
What are kinetic energy and its types?The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it. We must put in effort in order to apply force. After the work is finished, energy is transferred to the object, which then moves at a new, constant speed.
There are three types of kinetic energy and that is translational, rotational, and vibrational kinetic energy.
Kinetic energy depends on the velocity and mass of the object. Thus, velocity and mass are two factors that are used to calculate the kinetic energy of an object. Therefore, option B is correct.

Max has a group of goldfish in his tank at home. He notices that they are struggling a bit. Max wants to increase their rate of cellular respiration because he thinks that it would help them to survive. Which of the following actions would potentially increase the rate of cellular respiration in the goldfish?
A. reducing the amount of food placed in the tank
B. increasing the amount of carbon dioxide in the tank
C. increasing the amount of oxygen in the tank
D. reducing the amount of sunlight that hits the tank
Answers
Answer:
C. Increasing the amount of oxygen in the tank
Explanation:
If the fish are struggling or we see that they are going near the surface to breathe, that could indicate that there is not enough oxygen for the fish to breathe easily at all depths of the aquarium tank. By increasing the amount of oxygen present inside the tank we will assure that the fish have enough oxygen to live well. Not too much since too much oxygen can be bad for the fish.
The movement of water from an area of high concentration to an

The movement of
other molecules such as smoke or oxygen from an area of high concentration to an area of low concentration is called....
Answers
Answer:
1. Osmosis
2. Diffusion
Explanation:
The movement of water from an area of high concentration to an area of low concentration is called osmosis.
The movement of other molecules such as smoke or oxygen from an area of high concentration to an area of low concentration is called diffusion.
The movement of water from an area of high concentration to an area of low concentration is called osmosis.
Osmosis is a passive process that moves water molecules across a membrane that is semipermeable to solutes and other substances but impermeable to water molecules. The gradient in solute concentration determines the direction of flow, with water moving from areas of low solute concentration (hypotonic) to areas of high solute concentration (hypertonic) until equilibrium is achieved.
Osmosis is a fundamental process for preserving water balance in living things and is essential for many biological functions, such as cellular activity and water uptake by plants.

The answer is SUBSTITUTION MUTATION
Explanation:
A mutation is any change that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. One type of mutation is SUBSTITUTION MUTATION, which is a mutation in which one or more nucleotide base is replaced by another in the sequence.
Nucleotide bases are read in a group of three called CODON. Each of these codons specify amino acid. Hence, if the nucleotide base sequence is altered during mutation, the amino acid sequence is altered likewise. In this case where the original amino acid sequence is: Met-Ala-Gln-Arg-Glu-Leu, the mutation affected the nucleotide bases coding for Arginine (Arg), hence changing it to Glycine (Gly).
This means that a base substitution mutation occured, replacing the amino acid Arginine with Glycine in the mutated sequence.
Which organisms replicate cells by mitosis?
Answers
Answer:
All organisms, both prokaryotes and eukaryotes, can replicate cells by mitosis.
Explanation:
Mitosis is the process of cell division where, from a progenitor cell, two identical daughter cells are obtained. In the human being this process is carried out by somatic cells.
Cell division by mitosis is carried out by all living beings:
Prokaryotic organisms, unicellular, use it as a means to reproduce. Eukaryotic organisms, most of them pluricellular, use it in the processes of growth, development, repair and regeneration of tissues.All living beings can perform mitosis as a process of cell replication, although with different objectives.

What are the components of food web?A food web is defined as the cyclical event of energy transfer among different trophic level of organism.
The major components are primary producers, primary consumers, secondary consumers, tertiary consumers, quaternary consumers
Primary producers are the green autotrophic plants and capture some of the solar energy and convert it into chemical energy by photosynthesis.
The net primary productivity (NPP) of energy is defined as the rate of photosynthesis minus the rate of respiration of plants.
Primary consumers or herbivores feed on producers constitute the second trophic level of the food web.
in third tropic level, Secondary consumers eat primary consumers where as tertiary consumers, quaternary consumers or predators, carnivores or omnivores, which are both plant- and animal-eaters, such as humans.
