Symaptric speciation is the formation of new species in populations that live in the same geographic area, while allopatric speciation occurs when the population is separated by a geographcial area. So, according to this: The difference between the sympatric speciation and the allopatric speciation is that sympatric speciation involves a behavioral barrier, while allopatric speciation involves a physical barrier.

Answer:
Lower Respiratory Tract
Explanation:
The lower respiratory tract or lower airway is derived from the developing foregut and consists of the trachea, bronchi (primary, secondary and tertiary), bronchioles (including terminal and respiratory), and lungs (including alveoli). It also sometimes includes the larynx, which we have done here. This is where gas exchange actually takes place.

I need help on 3 Factor that affects population thingy. I don’t understand anything :(.
Answer:
Population growth (I think because birth rates, death rates affect populations)
Dispersion: There are three types of population dispersion are uniform dispersion, random dispersion, and clumped dispersion.
example question: "Describe the types of population dispersion, with examples, and the factors that influence them."
(I'm using this as a example to explain dispersion)
(things that affect dispersion) - Water supply, climate, shape of the land, vegetation, soils and availability of natural resources. In uniform dispersion, individuals of a population are more or less evenly distributed for example, allelopathy plants. In random dispersion, individuals are distributed randomly in the ecosystem for example, dandelions plants. Clumped dispersion is when individuals in a population are clustered together for example, pine trees. (or any forest)
Explanation:
Birth rates are a major factor because it is a continuous way for a population to grow, if you have low birth rates and high morality (Death rates) a population wont be balanced and death would largely out number the morality rate and time span of a population. That being the older population dies quickly because there is no younger populations to help them. This can lead to extinction too. Immigration is a population or group moving to the current one, it impacts population because its a very large group of new species being introduced to the current one adding numbers. This can also be bad because some immigrated species could be invasive and kill or take over the current/native species.
Example:
Algae blooms can reduce the ability of fish and other aquatic life to find food.

What is the difference between emphysema and asthma?
Emphysema is an inflammation of the lungs, while asthma is a bacterial infection of the lungs.
Emphysema is the gradual destruction of the alveoli, while asthma is a sensitivity to irritants that causes the airway to constrict.
Emphysema is a sensitivity to irritants that causes the airway to constrict, while asthma is the gradual destruction of the alveoli.
Emphysema is a bacterial infection of the lungs, while asthma is an inflammation of the lungs.
Answer:
Asthma and COPD are both chronic lung diseases. COPD is mainly due to damage caused by smoking, while asthma is due to an inflammatory reaction. COPD is a progressive disease, while allergic reactions of asthma can be reversible.With asthma, the swelling is often triggered by something you're allergic to, like pollen or mold, or by physical activity. COPD is the name given to a group of lung diseases that include emphysema and chronic bronchitis. Emphysema happens when the tiny sacs in your lungs (called alveoli) are damaged.
Explanation:

Describe the path of a phosphorous atom through four parts of the phosphorous cycle. Be sure to explain the processes involved in the transfers. Note when a form of phosphorous is available to plants. (Will mark brainliest)
Answer: One of the ways the path of a phosphorous atom starts is in a rock containing phosphate. The rock weathers, so that a phosphate ion enters the soil. A plant takes up the phosphate ion and incorporates it into a DNA molecule in a pollen grain. The grain falls back to the ground and decomposes, converting the atom back into phosphate through mineralization. The phosphate ion then leaches into the groundwater, leaving the soil.
Explanation: Plato/ Edmentum
Phosphorus moves in a cycle through rocks, water, soil and sediments, and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals.
This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil.
How does phosphorus enter the phosphorus cycle?
Phosphorus enters the atmosphere from volcanic aerosols. As this aerosol precipitates on earth, it enters terrestrial food webs. Some of the phosphorus from terrestrial food webs dissolves in streams and lakes, and the remainder enters the soil. Another source of phosphorus is fertilizers.

Just for the fun of it, someone walking along the shore in Beaufort, South
Carolina, throws a bottle with a message in it into the sea. Some time later,
someone in Perth, on the west coast of Australia, finds the bottle.
Referring to map, trace the path the bottle probably took! Make sure to
reference specific currents on your path.
The currents that carry the bottle from South Carolina to Peth are the West Wind Drift and the South Equatorial Current.
According to the information provided by the map, it can be inferred that the bottle that is thrown into the sea in South Carolina, USA and arrived in Perth, Australia took the following route:
It traveled down the Atlantic Ocean from the United States to the West Wind Drift current. Once there, it is transported from the west to the east, passing through the lower part of Africa and Asia until it reaches the Indian Ocean. When it reaches the Indian Ocean it is carried by the South Equatorial Current with a northeast direction. In this direction it reaches the coast of Peth, Australia.

escribe ONE way that the use of rodenticides affects the kit fox population AND explain how the size of the kit fox population is affected.
One way that the use of rodenticides affects the kit fox population will be a
reduction in the population.
Foxes are secondary or tertiary consumers which feeds on smaller animals
such as rodents in the ecosystem. The use of rodenticides will kill and
reduce the number of rodents available for food.
The reduction in the rodents means lesser source of food for the foxes and a
decrease in the population. The size of the kit fox population is affected
because a larger size being more affected than the ones with a smaller
size/population.

how is cytokinesis different in plant and animal cells
Answer:
The main difference between plant cell and animal cell cytokinesis is the formation of new cell wall surrounding the daughter cells. Plant cells form a cell plate between the two daughter cells. In animal cells, a cleavage furrow is formed between the two daughter cells.

science questions , may be out of order but please help asap ( about mitosis ) may be out of order so i made two questions
Answer:
8. Prophase
9. Gap 1
10.Metaphase
Explanation:
Basically from what I remember
Prophase: Mitosis begins, nuclear envelope is gone
Metaphase: Chromosomes line up and spindle fibers attatch
Anaphase: Chromosomes are torn apart to separate sides of the cell
Telophase: Separates duplicated genetic material into 2 identical nuclei
Cytokenesis: The cytoplasm itself separates and forms 2 cells.
Gap 1: Cells increase in size as new organelles are formed
Synthesis: DNA is formed
Gap 2: DNA is checked as cell begins to divide
Mitosis: Cell divides
So from the simplified versions of things I remember, I think the answers listed above probably suit each question best.
