Answer:
893 snakes after first year
Explanation:
total population= 900
death = 30 per year left= 900-30= 870
birth each year= 20 per year so 870 +20= 890 snakes
6 snakes migrate into the population = 890 + 6= 896 snakes
3 migrate out of the population per year = 896-3= 893 snakes
After accounting for annual birth rate, death rate, and net migration, the snake population after one year would be 893 individuals.
To find out how many individuals are in the population after the first year, we start with the initial count of 900 snakes. We then subtract the death rate, or number of snakes dying per year (30), add the birth rate, or number of snakes being born per year (20), then also add the net migration, or difference between snakes moving into and out of the area (6 entering - 3 exiting = 3 net influx).
So the calculation would look like this: 900 (initial population) - 30 (death rate) + 20 (birth rate) + 3 (net migration) = 893
Therefore, after one year, there would be 893 snakes in this population.

Answer:
DNA in eukaryotes have introns which are the non-coding sequences and are spliced out of primary transcript. They are not present in mature mRNA.
Explanation:
The reading frame of 50 or more nucleotides without any termination codon in between is called an open reading frame. The long open reading frames mostly represent protein-coding genes.
Hence, long open reading frames are searched for in order to find the genes. The presence of introns in eukaryotic DNA does not allow the application of this approach to find genes in eukaryotes.
The post-transcriptional modification of the primary transcript removes the introns. Hence, a mature mRNA does not have introns. Therefore, introns do not contain open reading frames.

Mating rituals or displays can be very complex but are also _______ behaviors.
When animals fight and one wins and one submits, this allows for the establishment of a _______. This means that one animal (the winner) likely gets to reproduce and lead the group.
_______ behavior is used to intimidate other animals in social interactions. Examples include baring teeth or growling.
_______ behaviors rely on prior practice or experience.
When a dog is sleeping and does not react to the sound of a person walking around the house, that is most likely an example of ________.
A common type of learning that involves experimenting to get a reward is called _______.
_______ is the pattern of behavior that follows the day/night cycle.
Many bird species have seasonal behaviors that cause them to _______ or change their location.
Explain how territorial behavior helps an animal population survive.
Answer:
Innate
fight or flight
innate
hierarchy
Aggressive
Learned
habituation
trial and error
Circadian rhythm
migrate
When animals mark their territory they ensure that the mates and food in their area are not overwhelmed. Though territorial animals often fight, it is not to the death, and more to establish social order. This prevents them from over-eating their environment and helps the entire species stay in balance to survive.
