Animals such as foxes and cats often prey on rabbits. Based on the growth curve of the rabbit population, what
might have happened if a group of predators moved into the rabbits habitat during the tenth generation and
began eating the rabbits?
Answer:
If this happened that would affect to amount of food the other predators got, eventually causing decreases in their species.
Explanation:
If a group of predators moved into the rabbit's habitat during the tenth generation and began eating the rabbits, it would definitely affect the amount of food and other resources that are available for other predators that directly or indirectly depend on the rabbit's population.
What is a Habitat?A habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection. In this natural environment, the basic demands of an organism are fulfilled like food, space, mating partner, etc.
When a group of predators starts eating the rabbits, the population of rabbits gradually decreases. Due to this, the other predators of the same species feel the scarcity of food and resources. As a result of this, their number or population also declines slowly or adapted to other species.
Therefore, it would definitely affect the amount of food and other resources that are available for other predators that directly or indirectly depend on the rabbit population.

what plate movements and earth features lead to the Earth Quake Prince William sound? (the Alaska Earthquake)
According to "M9.2 Alaska Earthquake and Tsunami of March 27, 1964",
On March 27, 1964 at 5:36pm local time (March 28 at 3:36 UTC) an earthquake of magnitude 9.2 occurred in the Prince William Sound region of Alaska. The earthquake rupture started approximately 25 km beneath the surface, with its epicenter about 6 miles (10 km) east of the mouth of College Fiord, 56 miles (90 km) west of Valdez and 75 miles (120 km) east of Anchorage. The earthquake lasted approximately 4.5 minutes and is the most powerful recorded earthquake in U.S. history. It is also the second largest earthquake ever recorded, next to the M9.5 earthquake in Chile in 1960.
The map shows the epicenter of the 1964 Alaska Earthquake (red star), caused when the Pacific Plate lurched northward underneath the North American Plate.

Explanation:
Active transport of fluid and electrolytes across the cellular membrane typically requires?
Active transport requires energy in the form of ATP conversion, carrier proteins, or pumps in order to move ions against the concentration gradient.
Active transport of fluids and electrolytes across the cell membrane normally requires the expenditure of energy (eg, in the form of ATP) to move a substance against its concentration gradient.
Active or passive transport?Passive transport is a great strategy for moving molecules into or out of the cell. It's cheap, easy, and all the cells have to do is stop and let the molecules diffuse.
In active transport, as opposed to passive transport, the cell expends energy (eg, in the form of ATP) to move a substance against its concentration gradient.
With this information, we can conclude that the active transport of fluids and electrolytes across the cell membrane normally requires the expenditure of energy (eg, in the form of ATP) to move a substance against its concentration gradient.

Why is plastic a non-biodegradable and nonpoint source of pollution?
Plastic is a non-biodegradable and non-point source of pollution because it cannot be broken down into degradable materials by micro-organisms. It comes from man-made substances and industries therefore, it is non-point pollutant.
What is Plastic?Plastic is a non-biodegradable and non-point pollutant. Because, the enzymes in the microorganisms cannot break down the waste into bio-degradable materials as microbes cannot recognize the bonds that hold these polymers together. Eventually, the polymers in plastic may break down, perhaps after hundreds of years. But after a long time, the damage is already done to the environment.
Nonpoint source of pollution comes from oil, pet waste, herbicide, bacteria, sediment, and any other contaminant that ends up on the ground naturally or from human activity.

(PLEASE HELP IF U CAN , 50 POINTS : NEED IT BY 11:59)
Answer:
Atomic Models Of Elements: Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). ... Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus.
Lithium:Lithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. because it is present in trace amounts in virtually all rocks.
Florine:Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium.
Electron:Electron is a free and open-source software framework developed and maintained by GitHub. It allows for the development of desktop GUI applications using web technologies: it combines the Chromium rendering engine and the Node.js runtime.
Neutron:The neutron is a subatomic particle, symbol n or n⁰ , which has a neutral charge, and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms.
Proton:A proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons".

Fill the container to the top with the particles. Place your hand tightly over the top of the container and shake it. What state of matter does this represent? Explain.
Answer:
It should be solid.
Explanation:
Solids have little to no movement in their particles. If you were to fill it to the top and shake, not much would move, therefore representing solids.
Particles are the unit that makes the matter. The states of matter based on particles can be solid, gas, or liquid. The matter in the experiment represents solid matter.
What are phases of matter?
The phases or states of matter are based on the composition and the distribution of the particles of the object. There are four known and observable states of matter namely solid, gas, plasma, and liquid.
The gas is the freest and most spaced particle with no fixed volume and shape. On the other hand, the particles of a liquid are a little closer than the gas but do have an indefinite shape.
The solid has particles closely packed with no space, which makes them have a definite shape and volume. When a container filled with particles is shaken, there is no movement as they are very closely packed, like solid.
Therefore, the container represents solid matter.

Some species of reptiles can regenerate body parts if the parts are lost due to injury. How can the reptiles regrow these body parts?
Answer:
the axolotl ( say "ax- oh- lot-el") is a Mexican species of salamendar . its also known as mexican walking fish .it can regenerate , repair or replace its arms,legs,tail ,lower jaw ,brain and heart
Explanation:
in reptile involves dropping a section of their tail and regenerating it as part of a defense mechanism
The reptiles regrow the body parts which are lost due to injury by the action of regeneration.
What is Regeneration?Regeneration may be defined as a process through which the reactivation of development into post-embryonic life in order to restore missing or damaged tissues is carried out.
The process of regeneration is carried out in Hydra (Morphollactic regeneration), Planaria (Stem cell-mediated regeneration), Salamander (epimorphic regeneration), and Mammalian liver (compensatory regeneration).
In reptiles like Salamander, epimorphic regeneration is carried out through which differentiated cell undergoes cell dedifferentiation in order to form regeneration blastema. This region is stimulated by the apical ectodermal cap (AEC).
Therefore, the reptiles regrow the body parts which are lost due to injury by the action of regeneration.
