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.

A mouse population that is originally white in color becoming darker in color after several generations is an example of natural selection.

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways.

Answer:

Evidence for these geomagnetic reversals can be found in basalts, sediment cores taken from the ocean floors, and seafloor magnetic anomalies. Reversals occur nearly randomly in time, with intervals between reversals ranging from less than 0.1 million years to as much as 50 million years.

Answer:

The allele for dark blue fish must be dominant and the dark blue parent fish must be homo-zygous dominant;

This would mean the dominant allele would necessarily be inherited by all offspring and since it is dominant, it would be expressed over the other allele (light blue fish)

Your bronchioles are some of the smallest airways in your lungs. Inhaled air passes through tiny ducts from the bronchioles into elastic air sacs (alveoli). The alveoli are surrounded by the alveolar-capillary membrane, which normally prevents liquid in the capillaries from entering the air sacs.

This question is in accordance with the mendel law of independent assortment which stated that two alleles assort independently during gamete formation. Therefore, the resultant punnett square will show flower having the genotype of RB and purple color as its phenotype.  See Attachment for punnet square results.

Answer:

D - design a device that can throw an object at least 15 metres

Answer:

D. Design a device that can throw an object at least 15 meters.

Explanation:

First of all, the object shown as you may be able to tell, look like a catapult. It also shows the top end of it holding a ball, getting ready to launch it. It then shows a line of the ball traveling after being launched. The balls land of the ground at 15 meters. From this iformation you look at the options:

A. Design an object that is 10 meters tall.

No, because 10 meter is just the highest point of the ball being launched.

B. Design a vehicle that can travel across a 10-meter feild.

No, because it is the ball that is traveling, not the catapult.

C is about a vehicle traveling again, so eliminate that too.

D. Design a device that can throw an object at least 15 meters.

This describes exactly what we soo in the picture. Meaning D is correct.

Photosynthesis is the process by which plants generate simple carbohydrates. This process used the energy from the sun.

In conclusion, in photosynthetic reactions, plants turn carbon dioxide (CO2) and water (H2O) into simple carbohydrates by using the energy from the sun.

Explanation:

C. Exposure to radiation during the disruption caused damage to parental gametes (sex cells) resulting in mutations in newborns is a valid claim that can be made about how the nuclear disruption led to mutations.

Radiation can cause mutations in DNA by damaging the genetic material, and these mutations can be passed on to offspring through the parent's gametes.

This is because radiation can cause mutations in DNA by breaking the chemical bonds that hold it together or by causing other types of damage that alter the sequence of nucleotides. Since gametes are the cells that are involved in reproduction and pass on genetic material to offspring, mutations in gametes can be passed down to future generations.

Somatic cells, on the other hand, are the cells that make up the body of an organism but are not involved in reproduction. Mutations in somatic cells can lead to health problems for the individual but are not passed down to offspring.

Therefore, in this scenario, exposure to radiation during the nuclear disruption likely caused mutations in the gametes of the local wildlife, which were then passed down to their offspring resulting in genetic mutations in newborns.
