Allopatric speciation is said to occur when two groups of organisms are separated by a physical or geographical barrier. Examples of such barriers are ocean, mountain range, rivers, etc. A good example of allopatric speciation is Galapagos finch. Different species of this bird can be found in different islands at Galapos, which is located at Pacific Ocean off South America. The ocean is barrier that isolate the species from one another.

Which of the following statements about idea models is not true?
a.
Idea models depict a concept.
b.
Idea models are typically used to predict natural disasters.
c.
Idea models are typically in the form of a graph or equation.
d.
Idea models are used to show the relationship between variables
the correct answer to this question is b
Answer:
The correct answer is the option A.
Explanation:In science, a model is a representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly. Models are central to what scientists do, both in their research as well as when communicating their explanations.Models are a mentally visual way of linking theory with experiment, and they guide research by being simplified representations of an imagined reality that enable predictions to be developed and tested by experiment.
Which of the following relationships correctly defines the situation: Lichen – cyanobacteria produces food for the fungus; fungus provides water and minerals for the cyanobacteria.
A. Commensalism
B. Predation
C. Competition
D. Parasitism
E. Mutualism
The answer is; B
Mutations change the order of nucleotide and therefore affects codons that code for proteins. A different protein is thus produced from the wild type hence creating variations. Genetic shuffling in sexual reproduction, also called gene recombination occurs during meiosis and also when different organisms exchange genetic material such as in bacteria.

A team of scientists altered the DNA of Pseudomonas bacteria. The bacteria thus developed had the ability to eat up oil. What could be the likely impact of this biotechnology on the environment and the society?
Toxic gases would be released, causing large-scale pollution.
Damage to marine flora and fauna due to oil spills could be prevented.
The consumption of nonrenewable energy sources would be increased.
The process of oil exploration would become simpler and more economical.
Answer:
B
Explanation:
If it can eat up oil, unleashing a swarm of these on an oil spill could help prevent damage that could be caused to the environment. Plus, we wouldn't need to dump the oil anywhere due to it being consumed.

If the concentration of a sugar solution is lower outside the cell than inside the cell, which will happen by osmosis?
The hypertonic solution has a lower water concentration than the hypotonic solution, so a concentration gradient of water now exists across the membrane. ... On the other extreme, a red blood cell that is hypotonic (lower concentration outside the cell) will result in more water flowing into the cell than out.
Answer:
Water molecules will move out of the cell
Explanation:
We are given that the concentration of a sugar solution is lower outside the cell than inside the cell. This means that a concentration gradient of water now exists across the membrane.
In Osmosis, we know that water molecules move from a less concentrated solution into a more concentrated one.
So in this case, water molecules will move out of the cell.

Answer:D
Explanation: all. Behaviors are innate
Answer: Mating is the correct answer.
Explanation: Innate behavior is also called instinctive behavior. Instinct is the ability of an animal to perform a particular behavior in response to a given stimulus the first time the animal is exposed to the stimulus. In other words, an instinctive behavior does not have to be learned or practiced. Answer is confirmed correct on test. I hope this helps you! Thanks!

All the complex feeding relationships among a number of different organisms make up the _____. ecosystem food chain food web
food chain or the food web is the answer, but im going towards the food chain :))
Answer: food web
Explanation:
A food chain is a linear sequence of transfer of food and energy when one organism is consumed by another organism in an ecosystem. The food web is a complex system in which a network of two or more food chains forms. It forms when organism belonging to one food chain feed upon the organism of other food chain.

In the pea plant, the allele for green pod color (G) dominates the allele for the yellow pod color (g). The Punnet square illustrates a cross for this trait. Which offspring can be described by these genotypes and phenotypes?
the color of the pea pods will be have a more of a chance to be green due to the fact that there is 75% of the square, because the big G means that it will be that color and if it has (gg) then it will be yellow.
Answer:
a) Homozygous offspring with yellow pod color - gg
b) Homozygous offspring with green pod color - GG
c) Heterozygous offspring with yellow pod color - None
Explanation:
It is given that green pod color (G) is dominant over yellow pod color (g).
Thus, an offspring will have green pod color, when its has heterozygous genotype (Gg) and homozygous dominant genotype (gg). While an offspring will have yellow pod color, only when it has homozygous recessive genotype (gg).
Thus, the offspring with under given phenotypes will have following genotypes -
a) Homozygous offspring with yellow pod color - gg
b) Homozygous offspring with green pod color - GG
c) Heterozygous offspring with yellow pod color - None , a heterogygous offspring will be green in color as green pod color is dominant over yellow pod color.

What phase of mitosis is shown in the diagram below
it is anaphase because yesterday i was studying this so yeah plz Brainlist me plz ill invite u to be my friend
Answer:
A. Telophase
Explanation:
When the anaphase ends, the DNA was separated an run towards both poles of the cell. The fibers from the centrosome retract and the nuclear membrane appears.
Also, when he nuclear membrane appears, DNA become descondensed so the Cytokinesis can begin and divide the plasma membrane to obtain the final two cells.
8) What are the differences between asexual reproduction and sexual reproduction?
A) Offspring are produced only by sexual reproduction.
B) An exchange of genetic material only occurs with asexual reproduction. C) Sexual reproduction involves one parent organism, while asexual involves two parent organisms.
D) Asexual reproduction produces offspring identical to the parents, while sexual reproduction produces offspring different from the parents.
Answer:Option D
Explanation:
The continuity of organism on Earth is maintained by the process of reproduction.There are two modes of reproduction. One is sexual reproduction and other is a sexual reproduction.
The asexual reproduction is the process by which identical progeny is produced by single parent. There is no need for two parent.
In case of sexual reproduction the offspring produced is not the exact copy of the parents they show variation. This variation in the offspring provides stability to the organism.
a specfic mutation in a certain animal leads to abnormal development of the heart and kidney, resulting in miscarriage. Why did this happen?
Answer:
These kinds of mutations are referred to as Lethal mutations
Explanation:
This type of mutation deleteriously affects the vital genes that are responsible for the core functions of the body. The heart supplies blood to the body organs for nutrients and oxygen while kidneys filter out toxins and end products of metabolism. Mutations in genes for development of these organs will be deadly.
