Answer:
Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.

Iron reacts with atmospheric oxygen to form iron oxide or ferric oxide. Look at the chemical equation for this reaction: Fe + O2 → Fe2O3
Answer:
This question is incomplete, the complete part is as follows:
This equation is unbalanced. Which of the following is the correct balanced equation for this reaction?
A. 4Fe + 3O2 → 2Fe2O3
B. 3Fe + 4O2 → 2Fe2O3
C. 2Fe + 4O2 → 3Fe2O3
D. 3Fe + 3O2 → 4Fe2O3
E. 4Fe + 4O2 → 3Fe2O3
The answer is A. 4Fe + 3O2 → 2Fe2O3
Explanation:
This question involved a chemical reaction between iron element (Fe) and atmospheric oxygen (O2) to produce iron oxide. The equation is given as follows:
Fe + O2 → Fe2O3
However, this chemical equation is NOT balanced and not in accordance with the law of conservation of matter. To balance this equation, we have to make sure that the number of atoms of each element on the reactant side is equal to that on the product side. Hence, we use COEFFICIENTS. The balanced equation is given below;
4Fe + 3O2 → 2Fe2O3

Cell phones, radar, and televisions are examples of devices that function by
using electromagnetic waves. What property of electromagnetic waves makes
them useful for phone, radar, and television signals?
A. Electromagnetic waves cannot be changed.
B. Electromagnetic waves can travel long distances.
C. Electromagnetic waves travel at different speeds.
D. Electromagnetic waves are harmful at high frequencies.
Answer:
es la C. Electromagnetic waves travel at different speeds.
The correct option is B i.e. Electromagnetic waves can travel long distances.
what are electromagnetic waves?Electromagnetic waves, or EM waves, are waves that are formed when an electric field and a magnetic field vibrate together. EM waves, in other words, are made up of oscillating magnetic and electric fields. When an electric field collides with a magnetic field, electromagnetic waves are created. As a result, they're called 'electromagnetic' waves.
An electromagnetic wave's electric and magnetic fields are perpendicular to one other (at right angles). They are likewise perpendicular to the EM wave's direction.
Cell phones employ radio frequencies, a type of electromagnetic energy found between FM radio waves and the wavelengths used in microwave ovens, radar, and satellite stations on the electromagnetic spectrum. Ionizing radiation, the type that destroys DNA, is not emitted by cell phones.

Answer:
d
Explanation:
Pick a cell found in the human body and analyze how the structure of that cell allows it to perform it's specific function in the human body.
Answer: Blood Cell
Explanation:
The function of the red cell is to carry oxygen from the lungs or gills to all the body tissues and to carry carbon dioxide, a waste product of metabolism, to the lungs, where it is excreted. The biconcave shape of the cell allows oxygen exchange at a constant rate over the largest possible area.
The function of the red cell is to carry oxygen from the lungs or gills to all the body tissues and to carry carbon dioxide, a waste product of metabolism, to the lungs, where it is excreted.
What is cell?Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.
Basically, cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.
The unicellular animals are made up of single cell and all the functions carried out in a single cell like amoeba and multicellular organisms are made up of multiple cells and there is specific cell for specific functions.
Therefore,the function of the red cell is to carry oxygen from the lungs or gills to all the body tissues and to carry carbon dioxide, a waste product of metabolism, to the lungs, where it is excreted.

What are the differences between three types of inertia?
Answer:
Explanation:
Inertia of rest - An object stays where it is placed, and it will stay there until you or something else moves it. ( Dust particles stay at rest until you shake a carpet.)
Inertia of motion - An object will continue at the same speed until a force acts on it. ( Body going forward when a car stops.)
Inertia of direction - An object will stay moving in the same direction unless a force acts on it. ( One's body movement to the side when a car makes a sharp turn.)

Identify the most efficient way to protect biodiversity. Explain your reasoning.
Answer:
Protect habitat
Actually a mass extinction event and the adaptive radiation that follows has been great for biodiversity in the past
Explanation:
Answer:
Hi there!
The most efficient way to protect biodiversity is by using habitat preservation. Habitat preservation helps all species in an ecosystem.
Explanation: This is the original copy of Boriscat's answer
Wildlife conservation is the preservation and protection of animals, plants, and their habitats. By conserving wildlife, we're ensuring that future generations can enjoy our natural world and the incredible species that live within it.
another answer:
Preserving habitats is essential to preserving biodiversity. Migratory species are particularly vulnerable to habitat destruction because they tend to inhabit more than one natural habitat. Altering a natural habitat even slightly can result in a domino effect that harms the entire ecosystem.
Another answer:
Habitat preservation is the best option for the species in an ecosystem not only does it help those in danger and as well as protect biodiversity but it also helps all species in an ecosystem.
WHY IS IT important to protect animals? not an answer just a q and a :D
For maintaining a healthy ecological balance on this earth, animals, plants and marine species are as important as humans. Each organism on this earth has a unique place in food chain that helps contribute to the ecosystem in its own special way. But, sadly today, many of the animals and birds are getting endangered.
