The idea that some sections of DNA can accumulate mutations fast while other parts accumulate mutations more slowly.

The idea that some sections of DNA are resistant to mutations and do not have them.

The idea that DNA evidence can be used to support evolution.

The idea that a section of DNA accumulates mutations at a constant rate over time.

Answer:

Random protein sequence 5 amino acids long

LYSINE - GLUTAMINE - VALINE - GLYCINE - LEUCINE

Explanation:

Proteins are macronutriens formed by amino acids. Amino acids are the monomers of proteins, meaning they are the structural units. These organic compounds are made of amino and carboxyl groups.

For every amino acid there is a DNA sequence:

Lysine: AAA

Glutamine: CAA

Valine: GTG

Glycine: CCC

Leucine: AAT

This protein sequence of 5 amino acids long would be like this in its DNA:

AAA CAA GTG CCC AAT

Complete question:

A population of wolves predates a population of moose on Isle Royale, Michigan, where there are fewer wolves than moose to start. The wolves prey on the moose and eat well, allowing them to have abundant offspring. However, as the wolf population rises, the moose population drops, and over time, the wolf population begins to drop also because of the reduced availability of resources. As the wolf population drops, moose are able to better survive and reproduce, causing the moose population to rise. With this abundance of moose, the wolf population is able to rebound until their population exceeds the moose population’s ability to support the number of wolves. Which population dynamic does this series of oscillations represent?

Answer:

Explanation:

The Delayed density dependence occurs when two species are in interaction (prey-predator or parasite-host), and the dynamic of each population follows the dynamic of the other population. The natality and mortality rates of one species follow the rates of the other species.

Delayed density dependence dynamics regulate populations and allow the occurrence of equilibrium or balance in nature.

Predator-prey scenarios

Assuming that the prey lives in the ideal environment with no predators, it shows an exponential growth rate. Prey can grow, develop, and reproduce, increasing its population size. The more available items, the more predator there will be. The predator population increase in size, and its presence affects the prey populations, leading it to decrease. So there are fewer available items to prey on.    

The prey population also affects the predator population. After the increase in the predator population size, the number of available prey decreases. The predator lives in an ideal environment but depends on the prey density. The more predators there are, the fewer prey there will be left. The predator population decreases exponentially due to the item's lack. The predation rate depends on density as well as natality and mortality rates.

So, to sum up,

In this particular example, the wolves population follows the moose population and vice-versa. It is not simultaneous. It happens with a delay.

Moose influences the wolf population because they are their source of food. The more moose, the more wolves there are. The fewer moose, the fewer wolves there are.

This is a density-dependent dynamic because both populations are affected when they reach a high value.

Explanation:

Answer:

Acid slant: yellow, fermentation of glucose and lactose and/or sucrose. High concentration creates excessive acid formation

Alkaline slant: red, limited glucose in the medium and limited acid formation.

The pH of acids is less than 7. Alkalis have a pH more than 7 The pH of neutral substances is 7. If metal oxides are soluble in water, they are alkaline. Non-metal oxides are acidic, if soluble in water.

An acid is a molecule or ion that can either donate a proton (Bronsted-Lowry acid) or form a covalent bond with an electron pair (Lewis acid). The proton donors, also known as Bronsted-Lowry acids, are the first type of acid.

Only dextrose fermentation produces an alkaline/acid (red slant/yellow butt) reaction.

The fermentation of dextrose, lactose, and/or sucrose is indicated by an acid/acid (yellow slant/yellow butt) reaction.

An alkaline/alkaline reaction occurs when as a result, carbohydrate fermentation does not occur.

The presence of red (alkaline) in the slant and butt indicates that the organism being tested is a nonfermenter.

The formation of hydrogen sulfide results in a black precipitate in the butt of the tube. The splitting and cracking of the medium indicates gas production.

Thus, these are the basic difference between acid and alkaline slant.

Answer:

Due to difference in volume of both atmosphere.

Explanation:

There is difference in volume of carbondioxide and oxygen gas between the atmosphere and  the exhaled air because of the volume difference of atmosphere and exhaled air. The volume of atmosphere is larger than the body from where the gases are exhaled. The body has lower space for these gases so these gases are less in concentration in the exhaled air which the body releases as compared to the atmosphere where the concentration of these gases are larger.

Answer:

1.This doesn't help COMPLETELY get rid of pollution. It might help lessen the pollution, but it definitely won't solve it, because there are also other things that cause pollution.

2.The main problem with solar power that has stifled its use is the fact that energy production only takes place when the sun is shining. And it won't be beneficial to the countries that aren't really close to the equator ( the middle east) and that might be a problem cause there just might not be enough energy/electricity.
