Why are human populations not limited by the carrying capacity of their ecosystems?

Answers

Answer 1

Answer:

humans use their knowledge to locate resources.

Explanation:

The carrying capacity can be defined as the maximum number of individuals in a population of a species that an ecosystem or region can support on the basis of availability of water, food, habitat and other needs necessary for survival. Sometimes, the population of the species increases exponentially exceeding the carrying capacity of an ecosystem when the resources available are surplus.  

The human populations are not limited by the carrying capacity of their ecosystem this is because of the fact human beings possess special intellectual and thinking abilities which make them capable of availing themselves resources. They posses knowledge which allows them to search, and find resources even from the earth extreme locations not suitable for survival.

How does an artificial pacemaker work?

Answers

It sends an electrical impulse to make your heart beat. The job of a pacemaker is to artificially take over the role of your sinus node if it isn't working properly. Electrical impulses are sent by the pacemaker to stimulate your heart to contract and produce a heartbeat

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.

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.

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.

(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

in order to survive in its environment a single celled organism uses a contractile vacuole to remove excess water that diffuses into its cell. Another species a hydra also excretes excess water. Both processes involve the use of energy. Based on this information, state whether these two organisms live in fresh water or salt water support your answer

Answers

Answer:

They would live in salt water.

Explanation:

Salt water is a hypertonic solution where water needs to move outside of the cell because there is too much solute outside. Because the 2 organisms are removing excess water, it shows that they are living in salt water where water flows outside instead of inside the cell.

Based on the available information, these two organisms would:

Live in salt water

According to the given question, we can see that there is a need for survival which makes a single celled organism to make use of the vacuole to remove the excess water which it diffuses into its cell.

As a result of this, we can see that another specie, a hydra also excretes excess water which involves the use of energy.

Therefore, the conclusion we can reach about them is that they are living in salt water because it is a hyper tonic solution which allows water to move freely outside the cell because of the excess solute outside the cell wall.

DONE

Answers

The cell wall gives cells shape, enables plant growth, prevents bursting from water pressure, keeps out water and pathogens, stores carbohydrates and sends signals to cells. The flexible cell wall surrounds plant cell membranes.

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.
