Answer:
Most populations <u>do not </u>experience: a) exponential growth
Explanation:
Populations that experience exponential growth models show an increase in proportion to their size. The increase in the population size depends on the individual´s reproduction rate: a population that grows at constant exponential rate gains individuals faster as the population increases in size.
This model states that populations live in an environment with unlimited resource availability, so the density factor does not influence population growth. There is no density-dependence effect nor competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita, and it is proportional to the population size.
Exponential growth is hardly seen in nature due to its characteristics.
Almost every environment shows a carrying capacity point. Carrying capacity is the capability of the environment to support a population. Commonly environments have limited resources and space, and as the population grows, competition increases too. The per capita growth rate decreases as population size increases. Finally, the population reaches the maximum point of carrying capacity, delimited by available resources, such as food or space.
The carrying capacity might be affected by limiting factors, which might be a result of the population density (for example, competition) or might be density-independent. This last case refers to dense-independent factors, and among these, we can mention human impact or natural disasters (fires, volcanic eruption, flooding).
Only a few species can experience exponential growth, such as bacterias.
Answer:
This loss can lead to coral death through starvation or increased vulnerability to diseases
Explanation:
Answer: due to insufficient exocytosis in the type II alveolar cells
Answer:
Activated
Explanation:
In the presence of lactose, and in the absence of glucose, lactose will bind to a protein called a "repressor," deactivating it. Through this, RNA polymerase has a free way to synthesize the mRNA that will give enzymes for lactose degradation.
Answer:
The question is incomplete, the correct question is;
Which statement describes asexual reproduction, but not sexual reproduction? A) New organisms are formed only after fertiliztion. B) A single cell will not develop into a full organism. C) Daughter cells contain half the genetic material of the parent cell. D) Daughter cells contain the same genetic information as parent cells.
Answer is option D. Daughter cells contain the same genetic information as parent cells.
Explanation:
The process in which organisms creates their offspring is called reproduction and the two types of reproduction are asexual reproduction and sexual reproduction.
In asexual reproduction, the offspring are produced from a single parent. They are genetically identical to each other and to the parent. Binary fission, fragmentation, and budding are the different methods of asexual reproduction. Examples of organisms which reproduce through asexual reproduction include bacteria, yeast, amoeba, hydra etc.
In sexual reproduction, the offspring are created by two parents and they are genetically unique. The gametes are reproductive cells present in the parents, produced by meiosis. They are haploid cells containing only half the number of chromosomes. The process in which the gametes from two parents combine to form a zygote (fertilized diploid cell) is called fertilization, where the zygote has twice the number of chromosomes. The zygote develops into a fully formed organism, which has a unique combination of characteristics inherited from both parents.
