3. A population of 820 insects lives in a 1.2-acre area. They gather nectar from a
population of 560 flowering plants. The plants live in a 0.2-acre area. Which population
has greater density, the insects or the plants? Why?
Answer:
Answer:
The plants have the higher population density. This is because, when compared with that of the insects, the number of plant species per acre area is higher; 2800 compared to 683.3
Explanation:
The number of individual species per unit area of land is known as the population density. Population density describes how crowded or spaced out a given species is in a particular area. The higher the population density, the more crowded the species are and vice versa. The formula for calculating population density is given as:
Population density = Number of species/land area
Population density of the insects = 820/1.2 = 683.3 insects/acre
Population density of the plants = 560/0.2 = 2800 plants/acre
Therefore, the plants have the higher population density.
This is because, when compared with that of the insects, the number of plant species per acre area is higher.
The population which has greater population density is the flowering plants with a population density of 2800 per acre.
Definition:
The population density is a measure of how crowded an area is. In essence, the population density of an area is simply defined as the number of species per unit land area.
Mathematically, the population density is evaluated as follows;
Population density = No. of species/Land area.As a result;
The population density of the insects is;P.D(insect) = 820/1.2 = 683.33 insects per acre.
The population density of the flowering plants is;P.D(flowering plants) = 560/0.2 = 2800 flowering plants per acre.
Consequently, the population which has greater population density is the flowering plants with a population density of 2800 per acre as opposed to 683.33 per acre of the insect population.

Michaela spend the day at the lake with some friends. She spends some time exploring the lake as she looks around she notices that there are plants only in certain areas where would she see plants growing? Why?
Answer:
She would mostly see plants grow around the banks of the lake. In addition, she might see some plants growing in the lake. The plants are majorly aquatic plants. The ones on the banks are emergent plants because their roots are submerged in water and their foliage is above water. They grow on the shores because it shallow there. Free-floating aquatic plants may grow in the lake because they are suspended on the water surface with their roots just floating underneath the water surface.

Which concept is part of the theory of evolution by natural selection?
 A. It is impossible to pass along traits from one generation to the next.  B. The best-adapted animals in a population cannot reproduce
 C. New generations are better suited to survive than previous generations.
 D. Evolution can only cause small changes to a species.
Answer:
C. New generations are better suited to survive than previous generations.
Explanation:
According to the evolutionary theory proposed by Darwin, evolution can be defined as a gradual process by which organisms change over time. Natural selection is the mechanism by which evolution occurs: organisms exhibit variation that may be passed from one generation to the next, and part of this variation confers an adaptive advantage. The organisms that are better adapted to their environment will have more chances to survive and reproduce, and they will pass these phenotypic changes to the next generation. At the species level, these phenotypic changes between generations are gradual, it is for that reason that evolution is a slow gradual process. In consequence, it is expected that new generations are better adapted to survive in the same environmental conditions.
Why are plains landscapes more likely to form meandering rivers than mountain landscapes
Explanation:
First, what are meandering rivers? Put simply they are rivers that flow in a zig-zag shape across the landscape. In other words, they curve in a back and forth manner.
On the mountain landscape, it is less likely for the rivers to curve back and forth because of the high elevation in the landform; which makes the back and forth shape pattern impossible, only a straight trajectory is possible.
one of the earliest events that distinguish meiosis from mitosis occurs in prophase 1 and involves
Answer:
This question lacks options, options are:
A. Pairing of homologous chromosomes
B. Movement of chromosomes towards the metaphase plate
C. Condensation of chromosomes
D. Loss of the nuclear membrane
The correct answer is A. Pairing of homologous chromosomes
Explanation:
Mitosis and meiosis are two different forms of cell division in eukaryotic cells, those that have a nucleus.In meiosis in Prophase I: homologous chromosomes pair up and exchange genetic material by crossing over. In mitosis in Prophase I: genetic material begins to condense and form long, thin strands. The mitotic spindle is formed.During the cell cycle, the eukaryotic cell undergoes a series of changes that lead to the formation of new cells. Depending on the type of cell, it can divide by mitosis or meiosis.

Chances of having a child with blue eyes - 50%
Chances of having a child with brown eyes - 50%
Explanation:
Many of our traits are determined by our genetics. We inherit genetic information from both of our parents. From each of them, we get one copy of a gene that determines a certain trait. These gene copies are called alleles.
The dominant allele is the one that masks the effect of the other type of allele, called the recessive allele. This means that a person needs to have only one dominant allele in order for its effect to be expressed. In order for the effect of the recessive allele to be expressed, the person needs to have two recessive alleles.
If a man has blue eyes, which is a recessive trait, he needs to have two recessive alleles (bb). This is why the genotype of the man is bb.
If his child has blue eyes, this means that its genotype is bb as well. The mother's eyes are brown, which means that she needs to have at least one recessive allele. Based on this, we can conclude that her genotype is Bb.
Since the mother has one dominant allele, this means that her children could have brown eyes as well. This is what the Punnett square would look like:
B b
b Bb bb
b Bb bb
Two out of four children would have brown eyes, and the other two would have blue eyes. This means that their chances of them having a child with blue eyes are 50%. The chances of them having a child with brown eyes are the same.

What are the conditions for exponential growth?
Answer:
The rate becomes ever more rapid in proportion to the growing total number or size.
Explanation:
Answer:Exponential growth may occur in environments where there are few individuals and plentiful resources, but when the number of individuals becomes large enough, resources will be depleted, slowing the growth rate. Eventually, the growth rate will plateau or level off.

Answer:
The correct answer is option C. the movement of water from the central vacuoles of the cells into the solution.
Explanation:
In the given question onion cell was initially in 1% NaCl solution later student increase the concentration of the NaCl in the solution which makes the solution hypertonic.
A hypertonic cell is a solution with less water or more solute. Increasing salt concentration makes solute concentration high than inside the cell. Cell shrink in this case due to the osmosis or water movement from the high concentration region of water to the low concentration of water region.
