Answer: A. A dog chases its tail in a circle four times.
Explanation:
Distance can be defined as a scalar quantity. It describes how much area the object covers during its motion. Displacement can be defined as the vector quantity. It refers to the fact that how far an object is from a place. It describes the overall change in the position of the object.
A dog makes a circle four times chasing the tail thus its direction will remain the same. Its position will remain the same after motion, thus no displacement will occur. The dog is making a circle on the same place while chasing the tail hence the distance covered will become equal to the net displacement.

Three friends were walking along a Beach in New England. They looked closely at the Sand and noticed it was made up of tiny particles of Rock. They had different ideas about where the Sand came from.
Answer:
the probability (assumptions)of where the sand came from by the three friends may be
a. the thought that the sand came from distant mountains and landforms.
b. the thought that the sand came from rocks on the ocean floor.”
c. he thought that the sand came from undersea mountains and sea floor formations.
the best answer to this is the first probability answer (a)the thought that the sand came from distant mountains and landforms.
it is very essential as a student to have an idea about weathering, erosion, deposition, and landforms. if students/ individuals can identify/recognize that sand on a beach may have come from distant mountains and landforms due to rock weathering , deposition or erosion.

Notice in the image of the plant that both oxygen and carbon dioxide enter and exit the plant. Using what you know about photosynthesis and cellular respiration, explain what is happening with regard to these two gases.
A) Unlike animals, plants use carbon dioxide in cellular respiration and produce oxygen.
B) Plants, as autotrophs, only undergo photosynthesis and both use and produce oxygen and carbon dioxide in this process.
C) Plants require oxygen for photosynthesis and produce carbon dioxide. Plants then use the carbon dioxide produced in cellular respiration, releasing oxygen as a byproduct.
D) Plants require carbon dioxide for photosynthesis and produce oxygen as a byproduct. Plants then use the oxygen released in cellular respiration, producing carbon dioxide as a byproduct.
Answer:
D
Explanation:
Plants first go through photosynthesis, using sunlight and carbon dioxide. This creates glucose. It then releases oxygen into the atmosphere as a byproduct. To convert the glucose into usable energy, the plant goes through cellular respiration, which converts oxygen and glucose into ATP.

A factory that has not followed pollution control standards has been operating in an area that did not have such a factory before. Plants that used to grow well are not doing well. Fish in a nearby river are dying at a higher rate than usual. Why?
A Pollution from the factory is getting into the rain, which is making the pH levels in the soil and water rise.
B It hasn't rained enough and the plants aren't getting enough water.
C The factory has increased the temperature in the area.
D Pollution from the factory is getting into the rain, which is making the pH levels in the soil and water become lower.
Answer:
D
Explanation:
If the pH levels are becoming low then the water and dirt becomes acidic killing fish and plants
Explain the role of lactate dehydrogenase in enabling C. parvum to continue producing ATP by glycolysis
Answer:
Lactate dehydrogenase (LDH or LD) is an enzyme found in nearly all living cells. LDH catalyzes the conversion of lactate to pyruvate and back, as it converts NAD+ to NADH and back. This is how it allows glycolysis to continue.
The lactate dehydrogenase enzyme carries the lactic acid fermentation.
What is Lactic acid fermentation?Lactic acid fermentation may be defined as a process through which muscle cells and bacterial species like Lactobacillus oxidize NADH by transforming pyruvate into lactate.
The enzyme lactate dehydrogenase carries the conversion of pyruvate into lactate. It involves the oxidation of NADH.
During this anaerobic process, ATP is produced in an average amount which provides the energy to muscle cells in oxygen-deficient conditions.
Therefore, it is well described above.

Butterflies usually are identified by the colors and patterns on their wings. Butterflies have four wings: The two wings near the butterfly’s head are “forewings” while the wings near the butterfly’s tail are “hindwings.” You can use the following dichotomous key to identify four common butterfly species in North America.
The shown butterfly in the diagram is - Papilio polyxenes.
Butterflies usually are identified by the colors and patterns on their wings. To identify an organism using a dichotomous key, compare the organism’s traits to the first pair of descriptive statements on the key.
Follow the directions after each matching statement until you get to the organism’s identity.The points on the hindwings identify the butterfly as
a swallowtail butterfly is either Papilio glaucus or Papilio polyxenes.1. Hindwings rounded ………………… Goto 3
2. Wings mainly yellow …………… Papilio glaucus
Wings mainly black ………….. Papilio polyxenes
3. Wings orange with black piping…Danaus plexippus
Wings yellow with black edges….. Colias philodice
The wings are mainly black, so the butterfly is Papilio Polyxenes (common black swallowtail)Thus, the shown butterfly in the diagram is - Papilio polyxenes.

Explanation:
The pattern of natural selection where BOTH of the extreme versions of a trait are more advantageous than the average, so a population evolves in both directions away from the average.
Answer:
Stabilizing Variation.
Explanation:
This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.
Organisms with varied or specific traits within the population are selected against by the selection pressure, with little chances of reproduction, while organisms in between, ( with least variation of this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives rise to narrow population of these particular organisms,(stabilizing variation) which are therefore naturally selected.
Therefore, the variation of the organisms in this population is kept close to the centre of the same mean value.

Earthworms, small insects, and microorganisms live in the soil and break down dead plants and animals. What would happen to an ecosystem if this process was compromised?
A.
The population of green plants in the ecosystem would increase.
B.
There would be more energy available to consumers in the ecosystem.
C.
The soil quality of the ecosystem would dramatically improve.
D.
The carrying capacity of the ecosystem would be limited.
Answer: D
Explanation:
Since the Earthworms, small insects, and microorganisms live in the soil and break down dead plants and animals. They end up playing a vital role in the ecosystem, if this were to be compromised nothing good would come form it Disease, competition, predator-prey interaction, resource use and the number of populations in an ecosystem all affect carrying capacity. If Earthworms, small insects, and microorganisms couldn't break down the the dead material and return it to the soil, then surely the carrying capacity would be drastically effected.
explain how gas is compressed into liquid in a gas barrel
Explanation:
A gas can be converted into a liquid by increasing the pressure & decreasing temperature. So that the condensation occurs. You must also make the molecules closer so that it is a phase change from a gas to liquid. In liquids, the molecules are very near than that of gases.
Food contains a sugar called , which is broken down in a process called cellular . This process uses to break down food molecules and provide energy for cells.
