Answer:
1- Option A) describes an index fossil. Trilobite existed for a short time, but was abundant and lived in many locations.
2- Option B) Continents were once joined and have since drifted apart.
Explanation:
1) Fossils are animal and vegetable rests found in different strata of sedimentary rocks. Sedimentary layers deposit chronologically, so they are used to reflect history. They keep in each layer some of the forms of life that inhabited that area in the past. These fossils turn to be very useful while dating ages. The term Index fossils refer to those fossils that only existed in a given era or geological period during evolution.
Index fossils must:
• Be easily recognizable and distinguishable from all the other fossils
• Have lived in a relatively short geological period
• Present a wide geographic distribution
• Have lived in different sedimentary basins
• Appear in different types of rocks
• Be abundant
A) Trilobite existed for a short time, but was abundant and lived in many locations. The species accomplish the requirements. It is easily recognizable, had a wide geographic distribution, was abundant, and lived for a short time.
2) The tectonic plates theory states that there is a continual movement of the crust. It explains the movement of the different plates and their directions and interactions. The continental drift theory explains how these movements have been taking place since millions of years ago. When continents were together in a unique continent, many species used to inhabit it. When plates started to separate, they took some of these species that got apart by the ocean. Some species were already dead and fossilized, while some other organisms died during continental drift and got fossilized after the divergence. The existence of the same fossils, placed in the same layers and of the same age, suggests that they used to inhabit the same area and died during the same time, meaning that continents were together when they got fossilized.

what is photosynthesis
Answers
Answer:
please tell me you know, my hands are literally shaking at how easy this question is
Explanation:
the answer is photosynthesis is a way for plants to make oxygen
still not enough information? they convert carbon-dioxide and water into oxygen and sugar, so they eat the sugar making their own food, put plants are living if they eat sugar. so they also have cellular respiration from mitochindria (photosynthesis is from chloroplasts and chrolophyll inside the chloroplast) and plants BREATH OUT SOME CARBON-DIOXIDE and produce more Oxygen than carbon-dioxide, thus providing the earth with Oxygen

Describe the flow of energy between the ant and antlion.
A. The energy flows from the ant to the antlion
B. There is no energy being exchanged
C. The energy flows from the antlion to the ant
Answers
Answer:
A. The energy flows from the ant to the antlion
Explanation:
Secondary Consumer
The option that describe the flow of energy between the ant and antlion is A which is that the energy flows from the ant to the antlion.
The food chain shows the transfer (flow) of energy and nutrients from organisms to organisms in a feeding pathway.
The flow of energy in a food chain of an ecosystem occurs in the following direction:
from the primary producerto the primary consumerto the secondary consumer andlastly to the decomposers.Primary producers are the green plants which obtains energy through the food they produced during the process of photosynthesis.
The primary consumers, for example the ants, feed on the plant saps thereby obtaning energy from it.
The secondary consumer, for example the antlion, feeds on the primary consumers (the ants) and energy flows from the ant to the antlion.

Although nondairy coffee lighteners made with coconut oil contain 2 grams of saturated fat per tablespoon, or 7 times more than does whole milk, those lighteners usually contain no cholesterol. Yet one tablespoon of such lighteners causes the consumers blood cholesterol to rise to a higher level than does an identical amount of whole milk, which contains 2 milligrams of cholesterol per tablespoon.
Manufacturers of coffee lighteners based on coconut oil claim that their products usually cause the typical consumer’s blood cholesterol to rise to a lower level than does the use of whole milk as a lightener.
Which one of the following, if true, provides the most support for the manufacturers’ claim?
(A) Consumers of lighteners made with coconut oil who avoid other high-cholesterol foods and exercise more than average tend to have lower-than-average blood cholesterol levels.
(B) Coffee is frequently consumed with pastries and other rich desserts that themselves result in high blood cholesterol levels.
(C) One popular nondairy coffee lightener that is not based on coconut oil has reduced its fat content by 20 percent while keeping its cholesterol content at zero.
(D) Consumers typically add to their coffee substantially smaller quantities of coconut oil-based lighteners than of whole milk.
(E) Most consumers are convinced that whole dairy products increase blood cholesterol and that nondairy coffee lighteners do not.
Answers
Answer:
The correct option that, if true, provides the most support for the manufacturers’ claim is (D) Consumers typically add to their coffee substantially smaller quantities of coconut oil-based lighteners than of whole milk.
Explanation:
This can be explained by analysisng each of the options as follows:
(A) Consumers of lighteners made with coconut oil who avoid other high-cholesterol foods and exercise more than average tend to have lower-than-average blood cholesterol levels.
We're looking for something that backs up the manufacturer's assertion. This option refers to a subset of people who share particular features that make them healthier than the general public. Therefore, this option is not relevant.
(B) Coffee is frequently consumed with pastries and other rich desserts that themselves result in high blood cholesterol levels.
What we are doing is a comparison of Coffee Lighteners to Whole Milk, and we're seeking for proof that the Coffee Lightener is better for cholesterol. Therefore, this option is not relevant.
C) One popular nondairy coffee lightener that is not based on coconut oil has reduced its fat content by 20 percent while keeping its cholesterol content at zero.
Other products are not important to us outside the one we are discussing. Therefore, this option is not relevant.
(D) Consumers typically add to their coffee substantially smaller quantities of coconut oil-based lighteners than of whole milk.
The impact of the cholesterol can be overlooked (important word here is “substantially”) if consumers use significantly less coffee lightener, which cannot be true for whole milk. If this is the case, the manufacturer's claim should be taken seriously and we should believe it. This is therefore the correct option.
(E) Most consumers are convinced that whole dairy products increase blood cholesterol and that nondairy coffee lighteners do not.
It does not make any difference whether consumers are convicted or not. What we are seeking for is actual evidence to back up our claims. Therefore, this option is not relevant.

The point that the kinetic energy increasing and its potential energy decreasing is Oz.
How to measure kinetic energy?To calculate the kinetic energy of an object with mass “m” and speed “v”, we must apply the formula Ec = mv²/2, where: Ec – kinetic in joules; m – mass in kg; v – speed in m/s.
What is potential energy?Gravitational potential energy that depends on the vertical position and mass of an object.
With this information, we can conclude that The point at which the kinetic energy increases and its potential energy decreases is Oz.
