All of the following are anthropoids from the Fayum EXCEPT Group of answer choices Oligopithecidae Eosimiidae Propliopithecidae Parapithecids
Given what we know, we can confirm that the animals listed that are not a part of the anthropoids are the Eosimiidae.
Why are they not anthropoids?The Eosimiidae' are a species of now-extinct primates that very closely resemble the anthropoid family. They were once linked to the anthropoids and thought to belong to this group due to their very similar traits and behaviors, over time, however, it was discovered that they did not in fact belong to this grouping.
Therefore, we can confirm that the animals listed that are not a part of the anthropoids are the Eosimiidae.

Answer:
hope it helps
Explanation:
There are three types of blood vessels:
Arteries carry blood away from your heart.Veins carry blood back toward your heart.Capillaries, the smallest blood vessels, connect arteries and veins.
Compare the relationship between carrying capacity and limiting factors
Answer:
The maximum population size that an ecosystem can support is called carrying capacity. Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem.

Hey mate here's your answer :-
The entire food webs of these dark, abyssal worlds would collapse. Shallower oceans would fare little better. Corals, which depend on microscopic algae and a surprisingly diverse collection of bacteria, would become weak and vulnerable.give one disadvantage of having a large number of stomata per mm squared of leaf surface
Answer:
The downside to wide open stomata is increased water loss (transpiration). So stomata of cool-season turfgrasses have decisions to make. The plant needs to capture and store energy via photosynthesis, however, excessive water loss through transpiration can result in plant injury or death.
One disadvantage of having a large number of stomata per mm squared of leaf surface might be the excessive loss of water.
What are stomata?Stomata are specialized plant structures used to exchange gases such as oxygen and carbon dioxide.
The plant structures (stomata) are especially located on the leaves where photosynthesis mainly occurs.
In conclusion, one disadvantage of having a large number of stomata per mm squared of leaf surface might be the excessive loss of water.

Are there any parts of the human body that get oxygen directly from the air and not from the blood? Are there nuclear reactions going on in our bodies?
Answer:
The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is the fastest healing tissue in the human body, thus, most corneal abrasions will heal within 24-36 hours.
Nuclear reactions do indeed occur in the human body, but the body does not use them.

What color is reflected back to cause plants to appear green?
Answer:
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.
Explanation:
Have a great rest of your day
#TheWizzer
The color that is reflected back to cause plants to appear green is the color green, as that is reflected back, the eyes can capture it, and as a result, the plants appear to be green.
What is the reason behind plants being green?Plants are green because of the presence of chlorophyll, a pigment found in plant cells. and this green color from sunlight is reflected back to the environment, and chlorophyll is crucial for photosynthesis, the process by which plants convert sunlight into energy, Photosynthesis occurs in specialized organelles within plant cells called chloroplasts. This absorbs light energy from the sun, and the absorbed energy is then used to power a series of chemical reactions that convert carbon dioxide and water into glucose, a form of sugar that the plant can use for energy.
Hence, the color that is reflected back to cause plants to appear green is the color green.

Suppose a new resort hotel is built on a hawksbill sea turtle nesting site, and hotel guests start removing the queen angelfish from the nearby reef to stock their home aquaria. If the hawksbill sea turtles and queen angelfish are removed, which organism is most likely to benefit?.
Answer:
Sponges, Anemones, Squid and Shrimp.
Explanation:
Those are the organisms that the sea turtle feed on.
Sponges, Anemones, Squid and Shrimp are most likely to benefit since the sea turtles and angelfish feed on them.
What happens if hawksbill sea turtles and queen angelfish are removed?Hawksbills contribute to the preservation of coral reef health. Reef fish have easier access to food because they clear sponges and other prey off the reef's surface. They are also valuable for tourism and have cultural significance.
Queen angelfish are omnivores that primarily eat algae and sponges. They are opportunistic and will consume jellyfish, soft corals, and sea fans. Young fish clean larger kinds of fish by removing parasites from their skin so that they can be eaten.
The populations of the organisms that Hawksbill Sea Turtles and queen angelfish consume, such as sponges and sea urchins, would probably explode if they became extinct. This would result in widespread erosion and possibly the collapse of marine ecosystems like coral reefs.

Which one below will end up being expressed in the protein?
a) Intron
b) Exon
c) Transcription factor
d) Terminator
e) Promoter
Exons are the DNA fragments that get to be transcripted and translated into proteins. Option b) Exons end up being expressed in the protein.
What are introns and exons?Even though more than 70% of the DNA is related to genes, just a part of the genes is translated to proteins. Most genes have DNA segments that are not transcripted or translated intercalated with segments that are translated.
Introns are non-encoding sequences that produce interruptions in a eukaryotic gene. Exons are the encoding sequences. Exons are the nucleotidic sequences that do codify proteins.Most of the eukaryotic, multicellular genes contain introns in their sequences, intercalated with exons.
Introns are transcripted to mRNA molecules and get excised before translation by a specific mechanism. This occurs before the mRNA leaves the nucleus. The introns are excised and the exons must splice to form a unique molecule. This process is known as splicing.
Exonic sequences are the fragments that are transcripted and translated into proteins.
The correct option is b). Exons end up being expressed in the protein
