The event that is associated with convergent boundaries is ; ( A ) Formation of Island chains
Island chains also known as Archipelago are a group of Islands evenly distributed in lakes, oceans and rivers within a defined area. with the Islands sharing a convergent boundary with each other.
Examples of an Island chain is the Mariana Islands and Japan where the chain of Islands share convergent boundaries.
Hence we can conclude that the event that is associated with convergent boundaries is the formation of Island chains .

Which component of a DNA synthesis reaction determines the exact nucleotide sequence of the product?
Answers
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.

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?
Answers
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.

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
Answers
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

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.
Answers
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.

Explanation:
In the text area below describe the function of the
cell wall.
DONE
Answers
Plant cell walls perform many functions. Their main task is to support proper plant growth. This is accomplished by the cell wall creating a skeleton-like frame that enables plants to grow vertically and develop a rigid stem. Cell walls vary considerably in thickness and organization, which accounts for the wide range of plant shapes and sizes on the planet. They consist of two layers ‰ÛÓ a primary cell wall, which supports the cell as it matures, and a rigid secondary cell wall that appears after the primary wall stops growing. The primary cell wall is thinner and more flexible than the secondary wall. Internally, the primary and secondary walls have a similar physical composition. Over the course of a plant's life, they perform complementary functions to keep the plant healthy and vibrant.
Answer:
The cell wall supports and protects the cell, determines the shape of the cell, assists cells in communication, stores carbohydrates, and allows water and smaller particles to enter the selectively permeable structure of the cell.

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
Answers
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.

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
