Fossils help scientists date rocks
Sometimes younger rock layers are found beneath older rock layers
The map of earth has changed over millions of years, but it is now set
No fossils from the Precambrian era have been found because there were no organisms at that time
Answer:
1. True 2. True 3. False 4. False
Explanation:
Fossils help scientist date rocks: Fossil presence is one of the most useful characteristics to date a rock, a fossil will set a specific geological age in which the organisms was present in the world, and vice-versa a new fossil can be dated by studying the age of the rock it was found. Answer: True
Sometimes younger rock layers are found beneath older rock layers: This phenomenon can be found in rock layers near the surface because process such as landslides that happen on the surface moves the surface rocks often resulting in older rocks appearing in the surface and younger rocks being buried by them. Answer: True
No fossils from the Precambrian era have been found because there were no organisms at that time: Although the number of organisms where very little organisms like algae (Stromatolites) were present in this era and fossils can be found. Answer: False
The map of Earth has changed over millions of years: but it is now set: The Earth crust is actually still moving, and will always move due to the tectonic plates and their movement caused by density and pressure, Nowadays The countries have moved from their once mapped location, because of this maps are needed to be updated by new geodesic measurements of the surface. Earth crust moves 2.5 centimeters per year. Answer: False

A mouse populations has various traits within its population. The mice have different fur colors, speeds at which they run, and different tolerances to a lack of food. If a new predator is introduced to the mice populations environment, which mice would be most likely to survive?
A. Fast mice that blend into their environment
B. Mice with a long tolerance for a lack of food, only
C. Slow mice that have a long tolerance for a lack of food
D. Mice that do not blend into their environment, only
Answer:
I'm thinking its A hope this helps!
Explanation:
Fast mice that blend into their environment mice would be most likely to survive, hence option A is correct.
How does mice survive in environment?Dark-coated mice are therefore difficult to spot for predators. As a result, their chances of surviving and reproducing are increased because they are more acclimated to this environment.
Predators are species that hunt and consume particular other animals. Additionally, they are described as beings that hunt and eat other living things.
Predators devour live things, which are referred to as “prey.” There are different qualities present in a mouse population.
Therefore, the mice differ in terms of the color of their fur, the speed at which they run, and how well they tolerate hunger. People alter their color to mix in with their surroundings.

B. An area on Earth that contains a ring of volcanoes
C. A giant landmass that existed over 250 million years ago
D. The process by which plates move
Answer:
C. A giant landmass that existed over 250 million years ago
Explanation:
Pangea was the Earth when the continents were mainly together and there was only one "continent".
Pangaea was a supercontinent that included all the landmasses n earth. The supercontinent was surrounded by super or mage ocean Panthalassa. It existed some 299 million years ago.
That existed in late Paleozoic to early Mesozoic era. Hence it includes all seven continents of the world known today. The giant landmass that existed over 250 million years ago.Hence the option A and C are correct.

Identify examples of adaptation in organisms
(Do not use the artic fox example)
Frog adaptations
- thin skin which allows them to breathe through their skin
- strong hind legs and feet allow them to jump long distances
- small, thin body structure which allows them to be excellent swimmers
- bulging eyes allow them to be better hunters
Answer:
Camouflage, mimicry, and animals' body parts and coverings are physical adaptations. The way in which an animal behaves is an adaptation, too—a behavioral adaptation. Behaviors that animals are born knowing how to do are instincts. A lion preying upon a zebra and a bird building a nest are examples of instincts.

AB->A+B+energy Which best describes this reaction A.)it's an anabolic reaction B.)it's an endergonic reaction C.)It's a photosynthesis reaction D.) It's A catabolic reaction
Answer: The option that best describes the reaction is D (It's a catabolic reaction).
Explanation:
Both plants and animals use the chemical energy in food to carry out the activities that are necessary for living,for growth and reproduction. These are metabolic processes which are divided into:
--> Anabolic process and
--> Catabolic process.
The Catabolic process involves the BREAKDOWN of large molecules with the release of energy. From the question:
AB -> A+ B+ energy
A typical example of a catabolic process that occurs in the body is cellular respiration which is the source of energy for the many anabolic processes that occur in a living organism. During a catabolic process (respiration),
--> stored chemical energy is released for doing work;
--> heat energy is given off;
--> large organic molecules are broken down into simple molecules.
The best describe option for the reaction AB → A+B+energy is It's a catabolic reaction.
What is a catabolic reaction?In catabolic reaction is the reaction, breakdown of large molecules is happens and energy is released.
The molecules such as glucose, protein, carbohydrates.
An example is the process of digestion is a catabolic process.
The metabolism process of the body completes in two process
Anabolic process
Catabolic process.
Thus, the correct option is D, It's a catabolic reaction.
