For any natural ecosystem, which of the following statements applies to the energy pyramid, the biomass pyramid, and the pyramid of numbers? *
1 consumes are at the bottom of the energy pyramid only
2 consumers form the bottom levels and producers are at the top
3 producers at the bottom of the biomass and energy pyramids only
4 producers are at the bottom of all three pyramids as they are the basis of all food chains and webs
Answer:
4
Explanation:
Producers are at the bottom of the energy pyramid because they prove the most energy, they make up most of the population, which is biomass. And the producers have the largest population, which is why they are at the bottom of the pyramid of numbers. Finally they are at the bottom of food chains and webs because they store the most energy inside of them.
Gorge and Hattie want to perform a set of experiments to test the optimal water and sunlight levels of a certain species of pea plant.
Gorge decides to test the amount of water that the species needs to thrive. He takes 24 pea plants and separates them into four equal groups and gives each group a different daily amount of water. He keeps all other environmental conditions the same for each group. He measures the initial height of all the pea plants and then measures their growth after one month.
Gorge averages the data from the individual pea plants and comes up with an average for each group, which he reports in the table below.
After Gorge's experiment is complete, Hattie decides to test the optimal sunlight exposure for this species. She takes 24 pea plants and separates them into four equal groups and exposes each group to a differing daily amount of sunlight. She keeps all other environmental conditions the same for each group, including giving each group 15 mL of water daily. She measures the initial height of all the pea plants and then measures their growth after one month.
Hattie averages the data from the individual pea plants and comes up with an average for each group, which she reports in the table below.
Which of the following conclusions can be made based on the results of these investigations?
A.

Explanation:
Why does ice have the lowest density?
Answer:
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

What is the function of a cell membrane?
Answer:
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
Explanation:
What are the subunits (monomers) of DNA and their function? O Monosaccharides that provide quick energy for the cell. O Lipids that store energy and provide insulation. O Proteins that provide the building blocks for the structures of organisms. O Nucleotides that store information.
Answer:
Nucleotides that store information
Explanation:
Deoxyribonucleic acid, commonly known as DNA, is one of the two nucleic acid biomolecules found in living systems. DNA is a polymer made up of long chains of monomeric units called NUCLEOTIDES. Nucleotides consists of three major subunits or parts namely: phosphate group, nitrogenous base (A,T, G, C) and a five-carbon sugar (deoxyribose).
Nucleotides are responsible for the functional and structural characteristics of DNA, which is to store GENETIC INFORMATION in living cells.
Where does the waste material in the body come from and why does the body need to get rid of these waste materials? Please help me!
Answer:
These waste materials are excreted out by the process of diffusion through general body surface. The removal of waste will help prevent the body from becoming ill, it will help clean the body inside and out, and will protect the body from infections.

Selectively permeable membranes are important in cell function. What makes a membrane selectively permeable?
A.The ability to remove bacteria from the cell
B.The ability to use energy to make proteins used in the cell
C.The ability to modify, sort and package proteins and lipids for storage or transport out of the cell
D.The ability to allow needed materials to enter and wastes to exit as well as the ability to block unneeded materials from entering the cell
The statement that makes a membrane selectively permeable is as follows:
The ability to allow needed materials to enter and wastes to exit as well as the ability to block unneeded materials from entering the cell.Thus, the correct option for this question is D.
What is a Selectively permeable membrane?A Selectively permeable membrane may be defined as a type of membrane that permits the entry of specific substances and the exit of a few substances but significantly prevents the transport of other substances through it.
This action of a selectively permeable membrane protects the cell from any unwanted impurities and damage. It also regulates the balance in the internal environment of the cell by the passage of toxic or unwanted substances outside the cell.
Therefore, the correct option for this question is D.

Which processes provides evidence for the claim that energy is transferred
during cellular respiration? Select all correct answers.
A. The electron transport chain
B. Carbon dioxide is released
C. hydrogen ions move down the concentration gradient across the inner membrane
D. transfer of electron carriers such as NADHand FADH2
E. water is formed
Answer:
B. Carbon dioxide is released
E. water is formed
Explanation:
Cellular respiration is defined as the metabolic processes in which chemical energy is converted into ATP and the waste product is released by the cells.
The processes that provide evidence for the claim that energy is transferred during cellular respiration are Carbon dioxide is released and water is formed. During cellular respiration, oxygen and glucose are converted into carbon dioxide and water, and the energy is transferred to ATP.
Hence, the correct answers are "B and E".

How is a hybrid different from its originating crops?
A hybrid crop is different from the original crops as they contain genes from other crops that are beneficial for them.
A hybrid has the genetic makeup of both of its parent crops but may have completely distinct external characteristics. This is due to the fact that two recessive genes from both parent crops can be fused together to create an outward visible impact in the hybrid.
Hybrid plants are the result of the cross-pollination of two plant varieties and the propagation of the seed resulting from the mix. The plant that emerges from this seed combination is known as a hybrid plant.

How many times farther from the Sun is Uranus (distance = 19.20 AU) than Saturn (distance = 9.58 AU)?
Answer:
Water is a polar molecule because one area is ________________ and another area is ______________________.
Explanation:
Uranus is approximately 2 times farther from the Sun than Saturn.
What is Uranus?Uranus is a planet in our solar system, orbiting the Sun at an average distance of about 1.8 billion miles (2.9 billion kilometers) or 19.2 astronomical units (AU). It is the seventh planet from the Sun and the third-largest planet in our solar system, with a diameter of about 31,518 miles (50,724 kilometers).
The distance from the Sun to Uranus is 19.20 astronomical units (AU), and the distance from the Sun to Saturn is 9.58 AU. To find how many times farther Uranus is from the Sun than Saturn, we can divide the distance to Uranus by the distance to Saturn:
distance to Uranus / distance to Saturn = 19.20 AU / 9.58 AU = 2.00
Therefore, Uranus is approximately 2 times farther from the Sun than Saturn.
