What is speciation? What are the causes of speciation? How does isolation lead to speciation?NO LINKS PLEASE
The biological species concept tells us that organisms belong to the same species if they can breed to produce fertile and viable offspring. Speciation is therefore the development of reproductive isolation between individuals of an original population.
This can occur in 2 different ways:
1. Allopatric speciation. This is when speciation occurs due to some sort of geographic barrier separates a population into 2 groups. These two groups can then undergo genetic divergence, where each group grows increasingly dissimilar genetically due to random mutations and natural selection acting separately in each group, or from processes such as genetic drift. It is important to recognize that the lack of gene flow between these two groups contributes to the genetic divergence of the groups. Genetic divergence can lead to prezygotic and post-zygotic barriers which prevent production of fertile/viable offspring between the 2 groups. Each of these populations now represents a new species, whose gene pools are completely separate from one another.
2. Sympatric speciation. This is when speciation occurs without the presence of any sort of physical/geographical barriers. Truthfully, this is a much less common occurence. However, it is thought that sympatric speciation can occur as a result of strong divergent selection. Sympatric speciation may also occur as a result of a polyploid individual being introduced into a diploid population.
Isolation leads to speciation by preventing gene flow between 2 groups of an original population, allowing genetic differences between the groups to accumulate over time (via natural selection, genetic drift, etc.). Over time, the accumulation of these genetic differences may result in reproductive isolation between the 2 groups, causing these two groups to be committed to separate evolutionary paths.
Answer: So, how might speciation happen?
Explanation:
Speciation describes a situation where a population in a species becomes so different that it can no longer successfully interbreed with other populations of the ‘same’ species.

What is adaptation? What are the two types of adaptation? Give an example each.
Answer:
adapting can be learning from your environment and ways to survive etc.
Adapting can also go to sexual reproduction to survive diseases unlike asexual reproduction.
An adaptation is a trait which increases the relative fitness of an individual. The fitness of an individual has 3 components: 1. Probability of survival to reproductive age. 2. Probability of attracting a mate. 3. Average number of offspring. Any trait which increases the fitness of an individual by positively impacting one of these three aspects is considered an adaptation.
There are 2 types of adaptation: physical and behavioral. These are self-explanatory. Physical adaptations could include things like adaptations to morphology or physiology of an organism. Behavioral adaptations are adaptations to, well . . . behavior :)

59:14 Organisms that live in the tundra have developed unique adaptations that aid in their survival. Ursus maritimus has a variety of adaptations which enable it to survive in the tundra. It is the largest terrestrial carnivore, but it is also an excellent swimmer that spends much of its time in and near the water hunting its favorite food. It has large paws with small bumps to provide traction as it walks across the ice. Its fur is helpful as camouflage during the winter months, but not as helpful during the summer. Which organism has the adaptations described that enable it to survive in the tundra
Answer:
Polar bear.
Explanation:
Polar bear is the organism that has the adaptations which enable it to survive in the tundra. the polar bear has white skin and fur on all its body which helps it to camouflage in the ice and to prevent the loss of heat from its body. The polar bear catch its favourite food in the water which is the fish that provide high nutrition to the polar bear. It is a good swimmer and have large paws with small bumps that helps it to provide support while walking on the ice. The scientific name of polar bear is Ursus maritimus whose features are described in the question.

Based on the living things in the pyramid, please tell me what examples would fit into these categories:
Primary Producers, primary consumers, secondary consumers, and tertiary consumers.
Answer:
Primary producer = Oak tree leaves
Primary consumer = Caterpillars
Secondary consumer = Blue j a y s
Tertiary consumers = Hawk
Explanation:
An energy pyramid is a graph which shows how energy is transferred or flows from one trophic level to the next. Organisms which occupy the same level in the food chain within an ecosystem belong to the same trophic level.
The shape of an an energy pyramid is a pyramid indicating that the number of living things as well as the amount of energy flow decreases as one goes from one lower trophic level to the next higher level.
At the base of the pyramid are the primary producers which use energy of the sunlight to manufacture their own food. Example is the Oak tree.
The next higher level is the primary consumers who feed directly on the primary producers. For example caterpillars.
The next higher level is the secondary consumers who feed on the primary consumers. For example the Blue j a y s.
The highest levelin the pyramid is the tertiary consumers who feed on the secondary consumers. For example, the hawk.

Explain how genetic mutations may result in genetic and physical variations (differences) within a population
The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism's DNA that create diversity within a population by introducing new alleles.

Explanation:

A heritable change in a person's genetic makeup is referred to as a mutation. Changes can be substantial or negligible. Chromosomes or chromosome parts may be lost, added, duplicated, or rearranged in significant alterations. Thus, option B is correct.
What mutation in a gene results in an animal?High-energy sources like radiation or chemicals in the environment can both result in mutations. They may also emerge on their own during DNA replication. The two main kinds of mutations are chromosomal abnormalities and point mutations.
Mutations can alter an organism's phenotype, which is its outward appearance, or they can have an impact on the way DNA encodes the genetic information (genotype). When mutations happen, they might kill an organism completely or only partially.
The likelihood that a gene mutation will cause an animal to be unable to produce the protein necessary for muscles to contract is that the animal will perish before producing any progeny.
Therefore, The animal will die before having any offspring.

i'm working on a lab report on water erosion on edg lol
pls help i'm so behind
is it okay??
Some facts about Water erosion :
Water erosion is the detachment and removal of soil material by water. The process may be natural or accelerated by human activity. ... Water erosion wears away the earth's surface. Sheet erosion is the more-or-less uniform removal of soil from the surface.
Water and Wind Erosion (cause)
Water erosion is the removal of soil by water and transportation of the eroded materials away from the point of removal. Water action due to rain erodes the soil and causes activities like gully, rill, and stream erosion leading to the downstream effects of flooding and sedimentation.

Can humans ever directly see a photon?
Answer:
Yes humans can directly see a photon.
Explanation:
In fact, photons are the only things that humans can directly see. A photon is a bit of light. Human eyes are specifically designed to detect light.
This happens when a photon enters the eye and is absorbed by one of the rod or cone cells that cover the retina on the inner back surface of the eye.
For Example
When you look at a chair, you are not actually seeing a chair. You are seeing a bunch of photons that have reflected off of the chair.Thus, Yes humans can directly see a photon.

3 ways in which our atmosphere is not like a greenhouse
( HELP ME PLEASE)!!!!
Answer:
1.) The atmosphere is an open system, with heat energy always escaping to space. Unlike the glass it absorbs 95% of the UV in the creation of ozone. This sounds insignificant, but one scientist argues variation in the 5 percent is the cause of warming.
2.) There are no winds in a greenhouse. In the greenhouse and in the atmosphere energy is partly transferred from the heated surfaces through collision between air molecules (conduction). However, in the atmosphere a large portion of that heat is transported vertically by rising air currents (convection), and also horizontally by advection or commonly wind. There are no winds in a greenhouse.
3.) Heat reduction in a greenhouse requires a physical change with a vent to let LW escape or a screen to block SW entering. Clouds are nature’s screen. However, they can block SW and LW, such that we have little idea how clouds work to modify temperatures
Explanation:
The basic idea of a greenhouse is that sunlight or shortwave (SW) energy passes through the glass and heats surfaces. The surfaces radiate that heat as longwave (LW) energy or sensible heat (heat you can feel). LW cannot pass through the glass, so is trapped and raises the temperature in the greenhouse; the glass acts like a one-way valve. A greenhouse is a closed system because the heat cannot escape unless artificially changed by opening vents or blocking sunlight. The glass supposedly represents the entire atmosphere. It also blocks 100 percent of the ultraviolet (UV) portion of the sunlight.
