The thing that makes a wave a wave is that it___________from one place to another.
A. Transport energy
B. Transports the medium
C. Travels with a vacuum
D. Carries Solids
Answer:
A?
Explanation:
All waves carry energy from one location to another, but they do not move any physical objects. The energy is transferred from one particle to the next, which then oscillates as well. Thus, option A is correct.
What is the energy transport property of wave?The vibration of particles, which transfers energy in waves, causes the particles to travel perpendicular to the wave's horizontal movement. As the particles transition from rest to movement and back to rest, energy is changed between potential (stored) and kinetic (moving) energy.
However, waves do not move mass. By colliding with one another and exchanging energy, the particles “participate” in the wave. Because of this, energy can be transferred even when the particles' average positions remain unchanged.
Therefore, The thing that makes a wave is that it transport energy from one place to another.

What are the differences between white blood cells and normal eukaryotic cells?
Answer:
White blood cells (WBCs) are specialized to respond to antigen and produce antibodies as well as undergo phagocytosis in response to toxic stimuli.
WBCs are part of immune system and there are five different kinds with specialized features.
In order to make a cell model, it is best to use a muscle cell and a nerve cell or neuron: there are pronounced structural differences and those are present throughout animal kingdom.
Lower animals ( such as insects, worms etc. ) have different immune system, however, they do have typical neuron and a muscle cell/skin cell (fibroblast). Such cell models are likely to be easy, distinct and bring you good grades without going through much complication and confusions of various organ systems and animal mod

If a SARS-CoV2 virus were to mutate and become and become better at attaching to respiratory cells, how would natural selection lead to this mutant virus becoming the dominant virus type? Use the four steps of natural selection in your response: overpopulation, genetic variation, competition, differential reproductio.
Answer:
Mutations leading to the better attachement of virus to the host cell would allow the virus to spread the infection and leave more progeny. The reproductive fitness of mutant viruses would allow the mutation to spread.
Explanation:
1. The organisms with same resource requirement compete with each other. Viruses are not living things but once inside the host cell, they behave like living things. Rapid multiplication of virus overpopulate the host cells.
2. Genetic variations are added to the viral progeny by random errors during replication of the viral genome. These random variations may impart beneficial trait, harmful feature or remain neutral. If a random mutation in the SARS-CoV2 virus allows it to adhere better to the cells of the respiratory system, the virus would be better able to infect these cells to spread the infection. Once inside the host cells, the mutant virus would leave more progeny. On the other hand, the wild type virus that lack this mutation would have lesser chances of entering the host cells and may or may not replicate.
3. The progeny of the mutant virus would compete better with the non mutant ones due to the presence of same mutation.
4. Differential reproduction and more progeny of the mutant virus would spread the mutation among the virus.

The culling of the cows was done as a means of preventing the spread of BSE
a.
process that determines which animals in a herd will not be bred
c.
The process of separating the herd by male and female
b.
taking blood samples from the cows
d.
all of the above
Culling of the cows to avoid the spread of the disease BSE is a process that determines which animals in a herd will not be bred.
What is culling?Culling refers to a selective slaughter of animals which are either infected or which have traits that make them undesirable.
The disease BSE is a disease that affects cows and which cannot be treated.
Therefore, culling of the cows to avoid the spread of BSE is a process that determines which animals in a herd will not be bred.

Which statement is NOT true of soils?
Weathered parent material makes up most of the B-horizon.
All of Earth's systems are represented in a soil.
The C-horizon of a soil can contain unweathered rocks.
Organic matter gives the A-horizon in a soil a dark color.
Answer:
b
Explanation:
The statement that is NOT true of soils is: "All of Earth's systems are represented in a soil."
How much soil is important on earth ?Soil is a critical resource on Earth, as it is essential for supporting plant growth and providing a habitat for a wide variety of organisms.
While soils are complex and dynamic systems that interact with many other Earth systems, not all Earth systems are represented in a soil. For example, soils do not directly represent the atmosphere or the hydrosphere, although they interact with both of these systems in important ways.
The other three statements are true of soils:
Weathered parent material makes up most of the B-horizon: The B-horizon is typically composed of weathered rock and mineral fragments that have been transported downward from the A-horizon.
The C-horizon of a soil can contain unweathered rocks: The C-horizon is the deepest layer of a soil and can contain unweathered bedrock or other geological material.
Organic matter gives the A-horizon in a soil a dark color: The A-horizon is the uppermost layer of a soil and is often darker than lower layers due to the presence of organic matter, which can give it a dark brown or black color.

how does spirogyra survive in a dry pond?
Answer:
I had a long answer that I would have loved to share but I can't because brainly does not like the words using and there is no way around it, tried using every synonym on the internet... LOL sorry
Spirogyra tends to grow in water in the spring, but when there is enough sunlight and warmth, it produces large quantities of oxygen, which adheres as bubbles between the tangled filaments. The filamentous masses reach the surface and appear as slimy green mats.
What are spirogyra?Spirogyra is free-floating green algae discovered in freshwater environments worldwide.
Spirogyras are filamentous algae with thin linear polymer chains of cylindrical cells that are named after their beautiful spiral chloroplasts.
Spirogyra is prized for human consumption in so many Asian countries and is recognized as an essential component of natural bioactive compounds used for antibiotic, antiviral, antioxidant, anti-inflammatory, and many more purposes.
In the spring, Spirogyra grows in water, but if it has enough sunlight and coziness, it produces large amounts of oxygen, which abides as bubbles seen between tangled filaments.
When the filamentous masses reach the surface, they form slimy green mats.
In a dry pond, using cell wall, it can survive and can get revive as the rain renew the pond.
Thus, this way spirogyra survive in a dry pond.
