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.

Telling Them Apart Suggest a way to distinguish between the two elements in each of the following pairs.
A. Bacterial cells; archaeal cells
B. Rough ER; smooth ER
C. Animal peroxisomes; leaf peroxisomes
D. Peroxisomes; lysosomes
E. Viruses; viroids
F. Polio virus; herpes simplex virus
G. Eukaryotic ribosomes; bacterial ribosomes
Answer:
A. presence or absence of phytanyl groups linked to glycerol
B. presence or absence of ribosomes
C. presence or absence of enzymes involved in photorespiration
D. presence or absence of catalase
E. presence or absence of coat proteins
F: Poliovirus's genetic material consists of RNA, while HSV's genetic material consists of double-stranded DNA
G. eukaryotic ribosomes and prokaryotic ribosomes have different sedimentation coefficients
Explanation:
Bacteria and Archaea are both prokaryotic organisms, but they have a different composition in their cell membranes. Archaeal membranes contain phytanyl groups linked to glycerol, while bacterial membranes contain fatty acids linked to glycerol. The rough endoplasmic reticulum (RER) has ribosomes (i.e., organelles that act to synthesize proteins), while the smooth endoplasmic reticulum lacks ribosomes. The leaf peroxisomes contain enzymes exclusively involved in photorespiration such as glycolate oxidase (GLO), which lacks in animal peroxisomes. Moreover, peroxisomes contain catalase, an enzyme that decomposes hydrogen peroxide (H2O2) to convert it into water, while lysosomes contain hydrolytic enzymes such as, for example, cathepsin proteases that degrade proteins. Viruses are composed of nucleic acids (either DNA and RNA) and coat proteins (capsids) while viroids consist only of RNA. Poliovirus is an Enterovirus (Picornaviridae family) whose genetic material consists of a single-stranded positive-sense RNA genome, while the genetic material of the Herpes Simplex Virus (Herpesviridae family) is double-stranded DNA. Finally, eukaryotic ribosomes have different sedimentation coefficients than their prokaryotic counterparts: prokaryotes have 70S ribosomes while eukaryotes contain larger 80S ribosomes.

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.

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).

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.

Which location has the warmer air temperature: Recife or Lima? Why?
Answer:
Recife has warmer air temperature because it is closer to the equator
Answer:Recife has the warmer air temperature
Explanation:Recife has the warmer air temperature.The first reason is that Recife,Brazil is closer to the equator than Lima,Peru which means Recife will receive more energy from the sun.Another reason is that the ocean currents that pass both locations have different origin.The current that passes Recife originated near the equator so that causes it to bring lots of energy causing the air temperature of Recife to be high and warm.The current that passes Lima originated near the South Pole so that causes it to bring less energy.Also Lima,Peru has upwelling as we see in the map and that also affects Lima,Peru to have colder air temperature

Membrane proteins offer structural support to the membrane but have no other function. Both plant and animal cell membranes are considered fluid mosaics.
Answer:
- In water, phospholipids spontaneously arrange into a bilayer
- Steroids in cell membranes allow the membrane to be more fluid
- Phospholipid bilayers surround all eukaryotic cells
- Both plant and animal cell membranes are considered fluid mosaics
Explanation:
All living things (i.e.. both eukaryotic and eukaryotic organisms) are composed of cells, and all cells have cell membranes. In an aqueous environment, phospholipids spontaneously form bilayers: hydrophilic heads of phospholipids face the water environment at the surface of the bilayer, while hydrophobic fatty acid chains are shielded from the water in the interior. Steroids are lipids that intercalate into the bilayer of the cell plasma membrane, reducing the fluidity of the membrane. Integral membrane proteins may have different biological roles. For example, permeases are integral membrane proteins that facilitate the diffusion of certain molecules (e.g., glucose) across the cell membrane by passive transport. Both plant and animal cell membranes are considered fluid mosaics where different types of molecules (e.g., phospholipids, cholesterol, proteins, etc) are constantly moving across the membrane.
