Olive oil contains unsaturated fat. It is a liquid at room temperature because
1)
the fatty acids do not contain carbon-to-carbon double bonds.
2)
carbon-to-carbon triple bonds exist within the fatty acids.
3)
the fatty acids are packed very tightly together.
4)
carbon-to-carbon double bonds are found within the glycerol.
5)
carbon-to-carbon double bonds exist within the fatty acids.
Answer:
4 or 5
Explanation:
Olive oil contains monounsaturated fatty acids (MUFAs), which have one unsaturated carbon bond in their chemical composition. MUFAs are typically liquid at room temperature.

1.What is the main factor causing the salinity of the Everglades to change?(1 point)
snake populations
flood control levees
climate change
transportation canals
2.Which animal was responsible for a 99% drop in the opossum populations in the Everglades by 2012?(1 point)
wading bird
fox
python
whooping crane
3.How are Burmese pythons and whooping cranes similar?(1 point)
Both species were relocated to new environments as pets.
Both species’ populations were affected by human actions that caused environmental changes.
Both species’ populations were almost wiped out because of a variety of environmental changes.
Both species became top predators in their new environments.
4.A student is conducting research on the impact of humans on whooping crane populations in the North America. Which statement best supports the student’s claim that animals have been positively impacted by human intervention?(1 point)
Captive-bred whooping cranes have been introduced to natural environments.
In the 1800s, North America was home to over 1,000 whooping cranes.
In the early 1900s, the U.S. and Canada jointly signed a migratory bird treaty.
Although the hunting of whooping cranes was criminalized, their numbers continued to decline.
Explanation:
1. The Burmese python is an invasive species in the Everglades ecosystem. This means its numbers increase dramatically due to lack of natural predators. The python is feeding on small mammals such as rodents that feed of egg of animals such as the turtles. This, therefore, causes a ripple effect on the food web in the ecosystem e.g dramatically increasing turtle population.
2. Due to the lack of natural predators in the ecosystem, the Burmese python causes an imbalance in the Everglade ecosystem. They reduce the biodiversity of the ecosystem hence diminishing the quality of natural resources.
3. The number of Burmese pythons can be regulated by introducing a predator in the Everglade ecosystem. Examples of animals that can prey on the snake are eagles, pumas, lions, crocodiles, cobras, and humans. This will reduce the numbers of the Burmese python and restore the balance in the ecosystem.
Climate change leads to salinity, the python is responsible, the populations were affected due to human actions that caused environmental changes. In the early 19th, America and Canada signed a migratory bird treaty.
What is the explanation of the above answers. ?The Everglades is a wetland preserve of southern Florida and is made up of coastal mangroves. Due to the impacts of the climate the region is under threat from the rising seawater and hence salinity is also one of the factors that are due to climate change.
The python is a species that is responsible for the 99% for drop in the level of the possum population of the everglades. The native Burmese's python is a cause of animal decline they are similar to the cranes because both of them are wiped by the environmental changes made by man.
As per the research of the student the impact of human whooping cranes in North America is due to the early 19th century both the US and Canada signed the migratory bird treaty.

one evening you see a crescent shaped moon that looks very narrow. a couple nights later you notice if again but it looks thicker. which phase is it in?
If one sees a crescent-shaped moon that looks very narrow one evening, and a couple of nights later one notices it again, but it looks thicker, then the moon is in the waxing phase as in option A, which is leading to the first quarter phase.
What are the different moon phases?The waxing crescent phase is the phase of the moon that occurs after the new moon phase and before the first quarter phase, where the illuminated part of the moon visible from earth gradually increases in size, and the moon looks narrower on the first evening and thicker on the second evening because the angle between the sun, Earth, and the moon is changing.
Hence, one sees a crescent-shaped moon that looks very narrow one evening, and a couple of nights later one notices it again, but it looks thicker; then the moon is in the waxing phase as present in option A.

32. An early consequence of the release of oxygen gas by plant and bacterial photosynthesis was to a. make life on land difficult for aerobic organisms. b. change the atmosphere from oxidizing to reducing. c. make it easier to maintain reduced molecules. d. cause iron in ocean water and terrestrial rocks to rust (oxidize). e. prevent the formation of an ozone layer.
Answer:
d. cause iron in ocean water and terrestrial rocks to rust (oxidize)
Explanation:
The Great Oxygenation Event (GOE) refers to the introduction of huge amounts of free oxygen into the atmosphere. This phenomenon was caused by photosynthetic cyanobacteria during the Paleoproterozoic, i.e., 2.5–2.2 billion years ago. During this period, oxidized iron minerals appeared in the soil and also were deposited on the deep ocean floor due to reactions with oxygen in the seawater from oceans. Moreover, during the Devonian (approximately 410- 360 million years ago), land plants greened the continents and it had brought higher levels of atmospheric oxygen, thereby increasing the amount of oxidized iron in the soil and rocks.
What does nitrate do to eluglena plz look at the picture but if the eluglena was increased would chloroplasts decrease?
Answer:
Euglena have been shown to successfully process nitrates as a form of nitrogen. Chloroplasts within the euglena trap sunlight that is used for photosynthesis So YES the chloroplasts would DECREASE. There is a blance to everything and if that blance is messed up then the plant will soon feel somthing wrong. If that makes since.

Which location has the warmer air temperature: Tarapoto or Neuquén? Why?
view the pic below.
Answer:
Palmas is closer to the equator than Neuquén. Which location has a warmer air temperature.Neuquén, because more energy is transferred from the sun directly to the air. Neuquén, because more energy is transferred from the sun directly to the surface, and then from the surface to the air.
Answer:
The climate in Tarapoto is hot, muggy, and mostly cloudy. Over the course of the year, the temperature typically varies from 70°F to 94°F and is rarely below 67°F or above 98°F.
And that is why the neuquen has the warmer air temperature!

Analogy and homology are important concepts used in comparing species. Traits are homologous if they are derived, evolutionarily and developmentally, from the same source structure. Traits are analogous if they have similar functions but are derived, evolutionarily and developmentally, from different source structures. A classic example of analogous structures is insect wings and bat wings. Which of the following pairs of structures are analogous and which are homologous?
a. Dorsal fins of porpoise and a salmon
b. Flippers of porpoise and pectoral fins (front fins) of salmon
c. Joined leg of ladybird beetle and a robin
d. Rhesus monkey's tail and human's coccyx
e. Bright red bracts of poinsettia and green leaves of rose
f. Red bracts on a poinsettia and red petals on rose
Answer:
a. analogous
b. homologous
c. analogous
d. homologous
e. homologous
f. homologous
Explanation:
a. Analogous. Porpoises are mammals while salmon are fish. In this case, fins are analogous structures that evolved separately in both groups.
b. Homologous. Pectoral fins evolved from the forearms of tetrapods, and early tetrapods evolved from fish.
c. Analogous. These structures evolved independently through convergent evolution in both groups.
d. Homologous. They are homologous structures that were inherited from a common ancestor (primates).
e. Homologous. Bright red bracts (modified leaves) of poinsettia and green leaves of rose share a common ancestor (i.e., angiosperms).
f. Homologous. They are homologous structures that were inherited from a common ancestor (i.e., angiosperms).
