Answer:true
Explanation:
where do convection currents occur.
A. in areas with the same temperature.
B. in areas with the same altitude.
C. in areas with different air pressures
D. in areas with different cloud types.
Answer:
the answer is C-in areas with different air pressures
Explanation:
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated.

What best describes the role of molecular oxygen (O2) in aerobic respiration?
A. It accepts electrons when reacting to form water.
B. It combines with carbon and hydrogen to form glucose.
C. It is released when glucose breaks apart.
D. It reacts to form carbon dioxide and water.
Aerobic respiration involves the reaction of oxidation which involves the acceptance of electrons when the molecular oxygen reacts with protons to form water molecules. Thus, the correct option is A.
What is Aerobic respiration?
Aerobic respiration is the chemical process in which molecular oxygen is used to make the energy in the form of ATP from carbohydrates. It is also called as aerobic metabolism, and oxidative metabolism.
Aerobic organisms can use molecular oxygen (O₂) to generate energy in the form of adenine triphosphate (ATP). The role of molecular oxygen in the process of cellular respiration is to act as the end acceptor of electron. As the electrons are dropped off at the inner mitochondrial membrane during the process of cellular respiration, they travel through the electron transport chain and are finally accepted by the molecular oxygen to form water.
Therefore, the correct option is A.

Heat energy is transferred on Earth by the processes of convection, conduction, and radiation. How does heat energy cause materials to move during convection? Complete the sentences below.
It causes denser materials to ______.
It causes less dense materials to ______.
Answer choices are Rise, Sink, Reflect, Absorb.
Answer:
Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower system.
In heat transfer by convection, heat energy causes denser materials to sink and causes less dense materials to rise.
What is heat transfer?Heat transfer refers to the process by which heat energy is transferred from one point at higher temperature to another at lower temperature.
Heat energy is transferred on Earth by the processes of convection, conduction, and radiation.
Thus, during convection, heat energy causes denser materials to sink and causes less dense materials to rise.

Trilobites
Trilobites were crab-like animals
that lived in ancient seas.
Scientists have discovered many
trilobite fossils all over the world.
However, the fossils only appear
in rocks that are at least 250
million years old. In more recent
rocks, their fossils are absent.
1. What conclusion would you
draw about trilobites based on
their appearance and
disappearance in the fossil
record
Answer:
The trilobites probably disappeared because either: A) they evolved into something else, or B) they died out due to the amounts of land rising out of the ocean.
If something's neural center dies, would you classify its cells as dead?
Answer:
No because only the neural organ died not the cells

What are three methods for detecting radioactively labeled DNA in an experiment?
Answer:
Limitations. detect low abundance DNA binding proteins from lysates. test binding site mutations using many probe configurations with the same lysate. test binding affinity through DNA probe mutational analysis. non-radioactive EMSA possible using biotinylated or fluorescently labeled DNA probes.
Explanation:
Answer:
Proteins interact with DNA through electrostatic interactions (salt bridges), dipolar interactions (hydrogen bonding, H-bonds), entropic effects (hydrophobic interactions) and dispersion forces (base stacking). These forces contribute in varying degrees to proteins binding in a sequence-specific or non–sequence-specific manner.

A. They are the only organisms capable of capturing energy
B. They are the only organisms that are green
C. They can recycle nutrients and water.
D. They can take energy from other organisms.
A
Producers get their energy from non-living resources
We can take out D
Of course, B is not it.
Now, we have either A or C.
Producers capture energy from sunlight, this means its A.
Which of these characteristics is NOT a property of water? (SC.912.L.18.12) A. Increases density as it solidifies B. Functions as a universal solvent C. Exhibits a highly cohesive behavior D. Moderates changes in temperature
Answer:
Option A.
Increases density as it solidifies
Explanation:
Increases density as it solidifies is not the characteristics of water because when water solidifies or freeze it become less dense or lighter compare to liquid water. When water solidifies to ice, it molecules are packed together and it is arranged in six sided crystalline shape which make it to be less dense or lighter than the liquid water molecules which is denser or more heavier.

Which of the following statements describes one way that energy is transferred in a food web?
Plants provide energy to consumers.
Energy is cycled between producers.
Consumers obtain energy directly from sunlight.
Producers store energy made by animals.
Answer: energy is cycled between producers
Explanation:
Plants provide energy to consumers, herbivorous and decomposers consumers are the only two groups that directly receive energy from plants.
What is a food web?The process of photosynthesis in plants transforms solar energy, which makes up the vast majority of the energy in food webs, into chemical energy.
When molecules are broken down during respiration in plants, a small fraction of this chemical energy is converted directly into heat. From producers to consumers, energy flows.
The relationships between species in a biotic community that involves eating are described by food chains, food webs, and/or food networks. In other words, they demonstrate the flow of resources and energy within an ecosystem from one species to another.
Therefore, plants provide energy to consumers one way that energy is transferred in a food web, hence option A is correct.

Rosa uses a microscope to compare and contrast a group of cells. She sees that the cells are joined together, so she knows that they are from one organism. She also sees that all of them have cell walls. Rosa could be looking at: (HIGHLIGHT THE CORRECT ANSWER)
Answer:
plant cells
Explanation:
Rosa could be looking at plant cells.
Plant cells are generally joined together when tissues of plants are viewed under the microscope and each cell is usually with a cell wall. Animal cells, on the other hand, do not have cell walls.
Tissues are generally composed of similar cells that have been aggregated together to perform a function in the body of organisms. Both plant and animal tissues consist of many cells but only plant cells have cell walls.
Red-green color blindness is an X-linked recessive disorder.

Answer: 25%
Explanation: This is the correct answer on Edge 2020 (just took the unit test review and made a 100%) ^-^.
X-linked recessive disorder refers to the genetic condition in which mutations or errors are associated with the gene are present on the X chromosome. The male will be affected by the disorder, while the females can be carriers.
In the given Punnett square, there is a 25% chance that the offspring can be -red-green color blind.
Red-green color blindness in people refers to the difficulty in distinguishing the colors like red, green, orange, and yellow. People with color blind have a normal life and there is no proper cure for the condition.
Thus, the percentage of the offspring that will be red-green color blind is 25%.

How are the functions of a cell similar to the functions of an organ system?
Answer:
Organelles in a cell are essentially the same as organs in an organism. The mitochondria is the powerhouse of the cell, as we all know. It creates ATP, which is what gives the cell energy. This is similar to how we consume food and create energy from it. Cell membranes are similar to skin, as they keep needed things in, and unwanted things out. Our cells need water too, as it helps create the cytoplasm. We need water to keep us alive and well, as it helps to create many of our needed bodily fluids, and rid us of toxins.
