Which of the following statements about exponential growth curves is true?
- a. Exponential growth curves are common for R-selected species.
Explanation:
The statement that is true about exponential growth curves is as follows:
Exponential growth curves are common for R-selected species.Thus, the correct option for this question is A.
What is an Exponential growth curve?An Exponential growth curve may be defined as a type of growth curve that significantly illustrates greater increases in the population of organisms with respect to time. It immediately represents the growth with extreme fast rates.
Exponential growth is followed by the continuous breeding population which contains more individuals than a similar population breeding annually. It includes examples like some insects, r-selected species, etc.
The shape of the exponential growth curve is J-shaped. It represents only fast growth rates. While the logistic growth curve shows fast growth rates followed by slow growth rates. It possesses a shape known as S-shape. It represents the growth rate of k-selected species.
Therefore, the correct option for this question is A.

access the capabilities of animal and plant cell types owing the presence or absence of chloroplast and cell wall
Answers
Answer:At this point, it should be clear that eukaryotic cells have a more complex structure than do prokaryotic cells. Organelles allow for various functions to occur in the cell at the same time. Despite their fundamental similarities, there are some striking differences between animal and plant cells (see Figure 1).
Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.

When you think of the American Southwest, you probably think of cacti, both big and small. If you were to
visit the American Southwest today, you might be disappointed with the lack of variation among cactus
species, especially right off the major highways. In 1926, Route 66 was the nation's first major highway to
allow visitors to visit the Southwest. Like many tourists, these visitors wanted to take home a memento of
their travels. Many people would pull over and begin looking for their own living souvenir. Since many of the
tourists did not have the necessary tools to extract a spiny cactus out of the soil, they usually had to make a
conscious decision about what type of cactus they should dig up. The cacti with too many spines were seen
as too difficult to dig out, and the visitors likely didn't have gloves to protect their hands. The cacti with too
few spines were seen as homely and were often overlooked. Therefore, the tourists found a cactus that was
between these two extremes. Over the last century, the phenotypic variation within these small cacti has
changed (at least in areas accessible by these highways).

Human urbanization would generally decrease the biodiversity of any forest because habitats and resources are lost during the process of urbanization.
Urbanization refers to the process through which cities are created out of urban areas.Cities are created by removing vegetation and erecting infrastructures such as buildings, roads, bridges, etc. The removal of vegetation means that habitats of organisms would be lost as well as the biodiversity that constitutes the vegetation itself.Thus, urbanization would automatically lead to a loss of biodiversity in the Amazon forest.

The cell membrane (plasma membrane) is describe as a highly selective
barrier composed of alipid bi-layer. This structure plays an important role
in moving molecules across the cell membrane in order for the cell to
maintain homeostasis. If the cell is unable to take in the materials it needs
or remove vwhat it does not need, the cell may die. This inability of cells to
maintain homeostasis may cause sickness or even death of an organism.
Why is it important that the cell membrane is highly selective?
O So that the cell wall is stabilized and maintains its rigidity.
O To prevent certain ions and molecules from entering or exiting the celI.
O So that proteins and lipids can attach to the membrane where needed.
O To allow movement of materials in and out of the cel.

O To prevent certain ions and molecules from entering or exiting the celI.
