Saprophytes are fungi that feed on dead and decomposing organisms. They secrete enzymes that digest components of cell walls, su

ch as cellulose and lignin. Which statement explains why these fungi are an important part of the biogeochemical cycle?
A) Saprophytes perform gas exchange that assists the cellular activities of autotrophs.
B) Saprophytes extract minerals from living tissue to recycle them back into the soil.
C) Saprophytes transport nutrients through the xylem and phloem in autotrophs.
D) Saprophytes return organic material to the soil for use by living organisms

Answer:

The answer would be D

Explanation:

This is true because one of the main things for fungi to do is breaking down materials, when they break materials down it is easier for them to mix in with the ground around them there fore causing them to be returned.

Answer:

D) Saprophytes return organic material to the soil for use by living organisms

Explanation:

Saprophytes are organisms that feed on organic matter originating from decomposition processes. They are heterotrophic because they obtain energy from organic matter in other living beings.

The main saprophytic living beings are terrestrial fungi and some species of vascular plants. They are essential for biogeochemical cycles, because they return organic material to the soil for use by living organisms.

In other words, we can say that saprophytes act as nutrient recyclers. They act in the process of decomposition of the substrate (place where they live), favoring the use of substances by other organisms. This process also favors soil fertilization.

Example: there are fungi that decompose rotting tree branches and stumps. The result of this process generates organic substances that serve as nutrients for other organisms in that ecosystem.

Suggest how a cell may vary the rate of an enzyme controlled reaction:<br> nt
Marina86 [1]

Answer:

A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less.

Explanation:

A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less. Several factors affect the rate at which enzymatic reactions proceed include post translational modifications, substrate concentration, cofactors, temperature, pH, locations. The shape and structure of the enzyme will change as the pH value of the reaction medium changes.

What is your opinion on Global Warming?
PolarNik [594]
My opinion is that EVEN IF there is anything that humans can do to save our species,
we will argue, debate, play politics, bask in absurd conspiracy theories, fritter around,
dilly dally, and totally ignore the urgency before us, until a time when nothing we're able
to do can any longer have any effect.  And that's my opinion.

Which disappears more rapidly from a population, a deleterious dominant allele or a deleterious recessive allele?
Allisa [31]

Answer:

Selection is a directional process that leads to an increase or a decrease in the frequency of genes or genotypes. Selection is the process that increases the frequencies of plant resistance alleles in natural ecosystems through coevolution, and it is the process that increases the frequencies of virulence alleles in agricultural ecosystems during boom and bust cycles.

Selection occurs in response to a specific environmental factor. It is a central topic of population and evolutionary biology. The consequence of natural selection on the genetic structure and evolution of organisms is complicated. Natural selection can decrease the genetic variation in populations of organisms by selecting for or against a specific gene or gene combination (leading to directional selection). It can increase the genetic variation in populations by selecting for or against several genes or gene combinations (leading to disruptive selection or balancing selection). Natural selection might lead to speciation through the accumulation of adaptive genetic differences among reproductively isolated populations. Selection can also prevent speciation by homogenizing the population genetic structure across all locations.

Selection in plant pathology is mainly considered in the framework of gene-for-gene coevolution. Plant pathologists often think in terms of Van der Plank and his concept of "stabilizing selection" that would operate against pathogen strains with unnecessary virulence. As we will see shortly, Van der Plank used the wrong term, as he was actually referring to directional selection against unneeded virulence alleles.

Goiters may occur due to iodine insufficiency, but other causes are possible. Which of the following would NOT tend to result in
AleksAgata [21]

Answer:

Option A

Explanation:

Thyroid is primarily caused by lack of iodine but there are other reasons as well that lead to increased size of the thyroid gland. Some of these reason is

a) over- or underproduction of thyroid hormones

b) Nodules in the glans

Some times, due to overstimulation immune system itself attack the thyroid gland thereby producing excess thyroxine and hence causing  the thyroid to swell

Thus, Option A is correct
