Answer:
The acts speakers perform when they make an utterance are called speech acts.
A speech act is an utterance that serves a function in communication. We perform speech acts when we offer an apology, greeting, request, complaint, invitation, compliment, or refusal. ... Here are some examples of speech acts we use or hear every day: Greeting: "Hi, Eric.
Explanation:
One important area of pragmatics is that of speech acts, which are communicative acts that convey an intended language function. Speech acts include functions such as requests, apologies, suggestions, commands, offers, and appropriate responses to those acts.

Chan Hee is inflating a basketball using an air pump. He notices that the pump gets warm as he uses it. What is a good
hypothesis that could lead to new experimentation?
If there is no air in a basketball, then it is hard to play the game.
A basketball that is inflated bounces better than one that is not inflated.
If air in a pump is squeezed more, then the air gets hotter because energy is added to it.
Basketball is more fun to play than baseball because you have to move a lot more.
Answer:
If air in a pump is squeezed more, then the air gets hotter because energy is added to it.
Explanation:
A good hypothesis in the given case is that inflating basketball is getting warmer, the more it is pumped, and as a result, it would possess more heat or more friction due to all the air being pumped into the basketball at a single time.

How does an artificial pacemaker work?
A pacemaker helps monitor and control your heartbeat. The electrodes detect your heart's electrical activity and send data through the wires to the computer in the generator. If your heart rhythm is abnormal, the computer will direct the generator to send electrical pulses to your heart.

Explanation:
A goal of using animal models is to explain the molecular detail of specific behaviors encoded in the human brain. How would you compare the developmental biology experiments on memory and learning using the fruit fly, drosophila melanogaster, as evidence about the evolution of a human behavior?
Answer:
It is possible to compare the expression of homologous genes in the brain of D. melanoganster and humans, because the expression levels of conserved genes may be associated with the evolution of cognitive features such as complex learning and memory.
Explanation:
Model organisms can be used to understand the patterns and processes that affect human evolution. Drosophila melanogaster is a model organism that has been used to study expression patterns of conserved genes in the course of evolution. This model organism has also been used to develop genetic mutant lines in order to examine the role of genes evolutionarily conserved in animals, including those involved in neurocognitive development.
In genetic research, an experiment as the above described is framed in a research field named 'Behavioral Genetics', which is a discipline that studies how evolutionarily conserved gene networks may be associated with neurocognitive tasks during brain evolution.
Which component of a DNA synthesis reaction determines the exact nucleotide sequence of the product?
Answer:
The complementary base pairing between incoming nucleotides and the DNA template
Explanation:
In a DNA synthesis reaction, the exact nucleotide sequence of the product is basically determined by both the DNA template from which a new strand is made and the incoming new nucleotides that makes up the new DNA strands. A complementary base Paris between these two gives the nucleotide sequence of the product.

When can exponential growth happen?
O A. When there is unlimited food and space
B. When the death rate is high
C. When carrying capacity is reached
D. When there is competition for resources
Answer: when there is Unlimited food and space
Explanation:
When there is unlimited food and space. Exponential growth occurs when a population has unlimited resources, such as food and space, and there are no limiting factors such as predation, disease, or competition for resources. In such a scenario, the population will continue to grow at an accelerating rate without reaching a carrying capacity. Hence option A is correct.
What is exponential growth?
Exponential growth can occur when there are no limiting factors that affect the population size. This means that the population has access to unlimited resources such as food, water, and space. In this scenario, the birth rate exceeds the death rate, and the population grows at an increasing rate over time.
As the population grows larger, the rate of growth also increases, resulting in a J-shaped curve on a graph.
However, in the real world, exponential growth is limited by factors such as predation, disease, competition for resources, and environmental factors like weather and natural disasters.
When these limiting factors are present, the growth rate of the population slows down, and the population may eventually reach a maximum size that the environment can support, known as the carrying capacity.
At this point, the population growth rate slows down to zero, and the population size stabilizes at or around the carrying capacity.
Hence option A is correct.

you are given a quadrat of 1.5 square meters and you count the
dandelions in 10 quadrats and find an average of 2 dandelions per quadrat
area. Use this information to estimate the population density of dandelions
per square meter in a 4500 square meter open field. (make your answer
just the number, round to the nearest 2 decimal places) *
Your answer
In a stable population of rabbits and wolves a government agency enacts a 1 point
Answer:
1.33 dandelions per square meters
Explanation:
The correct answer would be 1.33 dandelions per square meter of land.
Size of quadrat = 1.5 square meters
Average number of dandelions per quadrat = 2
Total study area = 4500 square meter
Population density = number of organisms per unit area
There were 2 dandelions per 1.5 square meters
How many would be per square meter?
= 2 x 1/1.5 = 1.3333 dandelion per square meters
To 2 decimal places = 1.33 per square meters

(1) What will be the frequency of the recessive allele in a population of 100 kangaroos if there are 50 dominant alleles?
a. 150
b. 0.75
c. 0.50
d. 0.25
(2) If the frequency of the recessive allele for a gene is 0.3, calculate the expected frequency of heterozygotes in the next generation if the population is in Hardy-Weinberg equilibrium.
a. 0.42
b. 0.21
c. 0.70
d. 0.30
Answer:
1. Option c
2. Option a
Explanation:
1. If there are 50 dominant alleles, this represent the frequency of dominant alleles p = 50/100 = 0.5
Using the formula p+q = 1 we can solve for the frequency of the recessive alleles q = 1 -0.5 = 0.5 = 50%.
2. the frequency of the recessive allele for a gene is 0.3 which is q = 0.3
From the Formula p + q = 1 we can solve for p the frequency of the dominant alleles = 1 - 0.3 = 0.7
To calculate for the number of heterozygotes, we use 2pq = 2 x 0.7 x 0.3 = 0.42
