Which best describes the ecosystem at Point C?
O A. There are plenty of resources.
B. Population growth is exponential
O c. The beetles are competing for resources
O D. It has not reached carrying capacity
Answers
Answer:
The correct answer is option C.
Explanation:
The graph shows that a controlled population of beetles, where other individuals do not leave or enter, experiences progressive growth from point A to C and plateau over time. This is because the population has sufficient resources to guarantee their development, the birth rate increases than the rate of mortality and there is no competition for these resources.
The adequate amount of resources allows that at point C, the carrying capacity is almost reached, which is the result of competition among members of the same species, which ensures that the net population growth rate is going to decrease or go stable due to limited resources..

C. The beetle are competing for resources

Which sentence best describes evolution? Populations remain the same over time. Individuals select different food sources due to competition. Inherited characteristics within a population change over time. An individual acquires certain traits during its lifetime.
Answers
Answer:
The inherited characteristics within a population change over time.
Explanation:
The evolution is related to the changes in the inherited characteristics over time in the biological population with the successive generation. These are inherited characteristics that are based on genes and passed from generation to generation through the process of offspring during reproduction.
Evolution can occur when the natural selection and the genes drift act together at the same level. The result is that some characteristics in the generation are common and some characteristics are different in this new generation.
Answer:Option C
Explanation:
Evolution can be defined as the change in the inheritable traits over successive generations.
The most preferable characters are selected by natural selection over a period of time. The organism having the desired trait will have more chances of survival as compared to the organism having no variation.
The characters that is inherited in the population changes over time is carried to the offspring.
Hence, the correct answer of this question will be option C.

The diagram shows embryo development of four different animals. How is this evidence used to suggest that life changes over time?
History of Life on Earth
All organisms have the same RNA at the beginning of development, but then the RNA changes over time to create new DNA for the differentiating characteristics.
Even in the early stages of development, these embryos are quite distinct from each other, indicating that life has changed over time to create this variety.
In the early stages of embryonic development, these four vertebrates are quite similar, indicating a possible common ancestor.
Late-stage embryonic development illustrates how, in spite of a common ancestor, each species has acquired differentiating characteristics over time that make each a unique species.
Answers
Answer:
C)In the early stages of embryonic development, these four vertebrates are quite similar, indicating a possible common ancestor.
Explanation:

What do you mean by embryonic development?The process by which the human embryo grows and develops is known as human embryonic development or human embryogenesis. The embryo's processes of cell division and cellular differentiation in the early stages of development are what make it unique.
Between the third and eighth weeks of pregnancy, approximately, the embryonic stage begins. The blastocyst starts to develop distinct human traits. Now it is known as an embryo.

Faster growing trees demand for wood can be met by trees that grow faster than average. Genetic engineering has produced trees that can ward off biological attacks, grow more quickly and strongly and creat better wood than trees that are not genetically modified. Do you think this is a good thing? Why or why not?
Answers
Answer:
Well, on one hand, this is a good thing as negative effects of the high demand for wood such as deforestation can be minimised. This will also sustain the supply of wood for several applications. However, there could be negative consequences of propagating such genetically-modified trees, which were not stated or are not yet known. For instance, the trees could be extreme soil nutrient consumers—depleting soil nutrients at a faster rate than they can be replenished and rendering such soil infertile in a short period.

What is the effect of building of roads in the rainforest?I am against of the opinion of building roads in the rainforest because there is no need for it as well as it increases human interaction with forest which leads to disturbance in the biodiversity and environment of the forest.
The construction of roads makes a way to establishment of more infrastructure around and in the rainforest which compels the organisms and biodiversity of the forest to migrate to other regions and in this way the rainforest will be destroyed.
So we can conclude that building of roads in the rainforest is a bad decision which can't be implemented.
