Which statement best summarizes "Save the Coral Reefs”?Coral reefs are a very important component of the ocean’s ecosystem becau
cupoosta [38]

Answer;

-Coral reefs are a very important component of the ocean’s ecosystem because they support sea life, such as crabs and sea turtles. In fact, over four thousand species depend on the survival of the reefs, which are being destroyed by bleaching. More must be done immediately to save the reefs.

Explanation;

-Coral reefs are important for many different reasons aside from supposedly containing the most diverse ecosystems on the planet.

-They protect coastlines from the damaging effects of wave action and tropical storms ( they provide a buffer, protecting our coasts from waves, storms, and floods, helping to prevent loss of life, property damage, and erosion) and also provide habitats and shelter for many marine organisms.

During upwelling, nutrient-rich water rises to the surface. How would this most likely affect the biotic components of the ecosy
hodyreva [135]

Answer: Increase in species numbers and diversity

Explanation:

Upwelling is an oceanographic phenomena in which the water from the bottom layers of the ocean usually above the seafloor get displaced and reach upto the surface layers with the effect of wind currents. The water carries away along with it the nutrients and the organic matter to the surface layers which allows the efficient growth of plant and planktonic diversity which favors the growth of sea animals like fishes and others. Hence, by this way the species diversity and numbers increases by the process of upwelling.

Part A - Modification of chromatin structure Which statements about the modification of chromatin structure in eukaryotes are tr
Salsk061 [2.6K]

Answer:

Some forms of chromatin modification can be passed on to future generation of cells

Acetylation of histone tails in chromatin allows access to DNA for transcription

DNA is not transcribed when packaged tightly in a condensed form

methylation of histone tails can promote condensation of the chromatin

Explanation:

chromatin modifications that can be passed on includes epigenetic modifications that are heritable changes made to the chromatin structure that does not involve the DNA sequences. Some epigenetic modifications include DNA methylation and Histone modifications. examples of histone modification include acetylation, methylation, phosphorylation, ubiquintylation etc. All these function either in allowing the DNA become more accessible to transcritional factors or vice versa. for exmple, histone tail acetylation encourages unwounding of nucleosomes allowing transcriptional factors to have access to the DNa while histone tails methylation further tightens the nucleosomes promoting condensation of the chromatin.

What information can not be obtained from the sequence of a gene? view available hint(s) what information can not be obtained fr
olganol [36]

The right answer is A.

The methylation profile of DNA is not obtained when DNA sequencing is performed.

Methylation is a process that can occur in DNA especially at the cytosine level. And this has a very important role in gene expression as it is part of the epigenetic expression.

Gene methylation can induce or repress gene expression depending on the localization of methylated bases.

What would happen if photosynisis stoped happing on earth
Neporo4naja [7]

We can confirm that the absence of photosynthesis on Earth would cause a mass extinction of most of the species on the planet.

<h3 /><h3>Why would the absence of photosynthesis be so harmful?</h3>

The process of photosynthesis is extremely important as it produces oxygen as a byproduct. The absence of this process on Earth would limit the available oxygen in the atmosphere which would at some point be entirely consumed. From then on, most species on the planet would die out as they require oxygen to live. Most plant species would also die off as they use photosynthesis to sustain life.

Therefore, we can confirm that the absence of photosynthesis on planet Earth could be considered an apocalyptic event as it would cause a near-complete extinction of life on the planet.
