How could fish-eating birds land on rocky islands be important in the formation of a new community of living things?

maks197457 [2]

Answer:

they would provide nutrients for new living things to feed on.

Explanation:

Fish eating birds would need important in the formation of a new community of living things because as they feed on these fishes on the rocks, they would also be eliminating wastes. The wastes that are being eliminated would serve as a source of nutrient on the Island. With time there would be enough nutrients for plants to tart growing

What organisms can get up to 10 centermeters in size

Svetach [21]

<h2>Answer:</h2>

A Single-Celled Organism

<h2>Explanation:</h2><h3></h3>

The giants of the deep are so-called xenophyophores, sponge-like animals that—like amoebas—are made of just one cell. They were found during a July research expedition run by the Scripps Institution of Oceanography in La Jolla, California.

The animals are about four inches (ten centimeters) long—among the largest single-celled organisms known to exist.

The creatures were discovered at depths of 6.6 miles (10.6 kilometers). That breaks a previous record for xenophyophores found in the New Hebrides Trench at 4.7 miles (7.6 kilometers).

Xenophyophores represent, "one of the few groups of organisms found exclusively in the deep sea," said Lisa Levin, a Scripps oceanographer who studied the expedition's data.

"If any creatures should be able to live at the ocean's greatest depth, then xenophyophores certainly should be among them."

The Mariana xenophyophores were seen in footage from Dropcams, free-falling devices equipped with lights and digital video that were developed by the National Geographic Society. (The Society owns National Geographic News.)

Protected by thick walls of pressure-resistant glass, the Dropcams were baited to attract whatever marine life might be lurking in the deep. Expedition scientists also saw, for instance, the deepest-swimming jellyfish to date. (Watch a video of the expedition.)

"The deep sea is the largest biome on Earth and holds much of the diversity on the planet—[yet it's still] largely undescribed," Levin said in an email to National Geographic News.

(Also see, "Pictures: Hard-to-See Sea Creatures Revealed.")

According to Jon Copley, a marine biologist at the U.K.'s University of Southampton, "many of the major discoveries in deep-sea biology have come from making direct observations at the seafloor."

"The Dropcam is a great tool for the future, because it can help us see more of what's down there for less cost than using ROVs or submersibles," he said via email.

For instance, "finding xenophyophores far deeper than before shows how much we still have to learn about our oceans depths and their inhabitants."

Tullis Onsott, an expert in deep-sea microorganisms at Princeton University, also called the xenophyophore discovery, "fantastic."

Which best describe fetus development?

mezya [45]

Prenatal or antenatal development is the process in which a human embryo and later fetus develops during pregnancy, from fertilization until birth. It is in between the embryonic state and during the birth. Fetal development begins at the gestational age of eleven weeks. The fetal stage is recognized when an embryo develop to the point where the major body organs is present.

If all living things are related then where did all their differences come from?

stiks02 [169]

Answer:

Hox Gene

Explanation:

First, you're question is very vital, there are many ways in classifying along with identifying all living organisms that includes; morphological analysis, molecular systematics (studying the similarities and differences of the genetic data such in the sequences of DNA, RNA, and rRNA ), homology, cladistics, etc. based on phylogenetic tree, which the study of the evolutionary among various species.

But through it said that all living organisms shared one common ancestor. However, what makes them different from one to another is the homeotic genes that called Hox Genes; which specify the fate of a particular segment or region of the body, meaning the number and arrangements of the Hox genes varies considerably among different types of animals.

For instance, Sponges have at least one homologous to Hox genes, also insects have nine or more Hox genes resulting in multiple Hox genes occur in a cluster in which the genes are close to each other along a chromosome. Therefore, increases in the number of Hox genes have been instrumental in the evolution of many animals species with greater complexity in body structure.

Overall, more Hox genes, more complexity in body structure resulting in the differences of their morphological structure.

Hope that answered your question!
