The picture below shows the fossilized remains of an insect trapped in amber. Amber is the
fossilized remains of tree sap. Which information can scientists learn by studying this sample?
Answers
Answer:
B. The type of insects that lived long ago
Explanation:
The point of amber fossils is that you get something that is more preserved and you can therefore analyze it better and determine what type of insect lived long ago.

1. a. processing
b. packaging
c. cleaning
2. a. decreases
b. stabilizes
c. increases
Answers
1. packaging 2. stabilizes
Answer:
Packaging and Increasing
Explanation:
Food processing offers a number of benefits. It helps remove toxins, preserves food quality, and enables clean packaging. The processing and preservation of food items drastically reduces the chances of food spoilage and the transmission of foodborne diseases. It also makes food items cheaper because of the lower cost enabled by mass production. Packaging simplifies the marketing and distribution of products, thereby increasing the availability of foods and perishable items around the world.

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
Answers
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.

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
Answers
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.

Sometimes younger rock layers are found beneath older rock layers: True
The map of earth has changed over millions of years, but it is now set: False
No fossils from the precambrian era have been found because there were no organisms that time: False
hope these are correct :)
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

How can you tell the stigma
from the stamens in a tubular insect-pollinated flower

B making more efficient gas-powered automobiles
C burning coal instead of wood in a fireplace
D mining for coal instead of drilling for oil
Answers
One way to reduce the use of nonrenewable energy resources is that make more efficient gas-powered automobiles. Thus, the correct option is B.
What is a Non-renewable energy resource?A non-renewable energy resource may be defined as a source of natural resources that can not be readily replaced by natural means at a speed quick enough to keep up with consumption. Such types of resources take millions of years to be synthesized.
Burning of coal, mining of coal, building additional gas-powered factories in rural areas, utilization of nuclear energy, etc. are not the measures that are helpful in the reduction of usage of nonrenewable energy resources.
If we want to reduce the usage of non-renewable energy resources, it is required to be less dependent on such resources.
Therefore, one way to reduce the use of nonrenewable energy resources is that make more efficient gas-powered automobiles. Thus, the correct option is B.
