Question 2 (11 points) What conclusion can be drawn from the change in population of light gray peppered moths and the dark-colored moths? The color change had nothing to do with the change in environment. There were previously no dark-colored pepper moths. Darkerd coloring is currently better for the peppered moth's survival. The lighter peppered moths migrated to a new environment. d
Answer:
Darker coloring is currently better for the peppered moth's survival.
Explanation:
Dark coloring is currently better for the peppered moth's survival because this dark colour enable the peppered moth to hide from the birds who feeds on them. Due to industrial revolution, a black powder of smoke emitted from industries spreads on the vegetation. This black powder helps the dark peppered moth to hide from the predators so it increases the survival of peppered moth.
Place the steps below in order from the first to happen to the last that will happen in hemostasis. Chemicals are released from the injury site and from underlying callogen. A blood vessel is severed. Blood and blood components leak out the breaks. The platelets become activated making them spiked and sticky. Fibrin forms a mesh that traps more platelets and erythrocytes, producing a clot. Fibrinogen is converted to fibrin. The smooth muscle in the vessel wall contracts near the injury point, reducing blood loss.
Answer:
A blood vessel is severed.
Blood and blood components leak out the breaks.
Chemicals are released from the injury site and from underlying callogen.
The smooth muscle in the vessel wall contracts near the injury point, reducing blood loss.
Fibrinogen is converted to fibrin.
The platelets become activated making them spiked and sticky.
Fibrin forms a mesh that traps more platelets and erythrocytes, producing a clot.
Explanation:
Hemostasis is the process by which the body prevents and stop blood loss through bleeding.
Hemostasis occurs in three steps:
1. Vasoconstriction: Once a blood vessel is severed or cut, the smooth muscles of the blood vessels start to constrict or get narrower around the severed vessel in order to reduce blood flow through it. This vasoconstriction occurs in response to chemicals released from the cut vessel and the underlying collagen.
2. Platelet-plug formation: the platelets become activated by a glycoprotein called Von Willebrand factor (vWF), which is found in plasma and begin to clump together sticking together. This is known as primary hemostasis.
3. Clot formation: in response to platelet-plug formation, several clotting factors are activated which eventually convert fibrinogen to fibrin. Fibrin is mesh-like and holds the platelets as well as red and white blood cells in place, thereby forming blood-clots over the wound.

DNA is made up of monomers called nucleotides. How many does mono- represent?
Answer:
It is often said that life is “carbon-based.” This means that carbon atoms, bonded to other carbon atoms or other elements, form the fundamental components of many, if not most, of the molecules found uniquely in living things. Other elements play important roles in biological molecules, but carbon certainly qualifies as the “foundation” element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role.

Imagine you are a systematist who has discovered an unfamiliar
animal. Which of the following observations about the animal will best
help you find its taxonomic classification?
The animal has an unpleasant temperament.
The animal has sharp, pointed teeth.
The animal was found near a herd of deer.
The animal bit you.
Answer:
1) taxonomy
2) species
3) the animal has sharp, pointed teeth
4) the current taxonomic system is based on the Linnaean system
5) he only had two kingdoms, animals and plants
Explanation:
did the quick check
The observation about the animal that will be helpful in finding its taxonomic classification is B. The animal has sharp, pointed teeth.
Taxonomy refers to the science of the classification of organisms into groups. The classification is based on the characteristics that the organisms have.
Therefore, in a situation whereby the person is unfamiliar with an animal, the shape of the teeth of the animal can be used for its classification.

Differentiate between the three major climate zone
Answer:
tropical, temperate, and polar
The three major climate zones are tropical, polar, and temperate.
What are the climate zones?A larger pattern, which helps one to understand weather is known as climate. The climate of the region is predicted by the average weather in the location over a long time duration. The three prime climate zones of the Earth are:
TropicalTemperatePolarThe climate region close to the equator with warm air masses is called tropical. In this climate zone, the average temperature in the coldest month is 18 degree C. This is warmer in comparison to the average temperature of the warmest month in the polar zone.
The polar climate zone is found in the North and South poles due to adjacent cold air masses. In this zone, the warmest months average is less than 10 degree C. This is lesser in comparison nto the average temperature of the coldest months in the tropical zones.
The climate zone situated between the North and South poles and the equator is the temperate zone. The average temperature of the coldest months in the temperate zone is lesser in comparison to the tropical zones, while the average temperature of the warmest months in the temperate zone is more than that of the polar zone.
Thus, the three major climate zones are tropical, polar, and temperate.

what provides new variation
Answer:
Mutation
Explanation:
The main cause of variation within a population is usually through genetic mutation.
Mutation is the alteration of the genetic sequence within an organism. It often lead to formation of new genetic patterns and codes.
Most times, environmental influences are paramount to causing genetic mutation within a population.
Other times, it might be due to competition and some other internal factors.
Mutation can be transferred from parents to offspring in most cases.

Answer:
Due to suitable environment of the equator.
Explanation:
Latitude is abiotic factor that has a great impact on the occurrence of fish species as we can see in the graph, the fish species increases as we go towards equator whereas decreases when we go away from the equator. This is because the climatic condition and temperature of water at the equator is suitable and warm so this suitable environment attracts more species to lives there.

A radioactive element has a half-life of 2,000 years. If a sample of this
element begins with a mass of 100 grams, how long would you have to waitfor the mass to decrease to 25 grams?
A. 4,000 years
B. 8,000 years
C. 500 years
D. 2,000 years
Answer:
A = 4000 years
Explanation:
Given data:
Half life = 2000 years
Total mass = 100 g
Mass remain = 25 g
Time taken to reduces to 25 g = ?
Solution:
At time zero = 100 g
At first half life = 100 g/2 = 50 g
At 2nd half life = 50 g / 2 = 25 g
Time taken:
Half life = Time elapsed / number of half lives
2000 years = Time elapsed / 2
Time elapsed = 2000 years × 2
Time elapsed = 4000 years
