Answer: Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
The process in which impurities are removed from a mineral
Answer:
The removal of impurities is usually done chemically. For example, in the manufacturing of iron, calcium carbonate is added to the blast furnace to remove silicon dioxide from the iron ore. Zone refining is an economically important method for the purification of semiconductors.
Explanation:
The genetic diversity of a rocky shore habitat declines precipitously as the climate warms, causing a decline in the number of species present. The decline of species along the rocky shore negatively affects the entire region, including bird populations and shallow offshore habitats. This scenario is best described as a change in the region's ______________________.
The scenario that is best described here is a change in the region's BIODIVERSITY. This measure (biodiversity) indicates the genetic/phenotypic variability found in a region.
Biodiversity refers to the genetic and phenotypic variability of the organisms found in a particular geographic region or the variety of life on the Earth's planet.
Biodiversity can be used to indicate the amount of variation at different levels (i.e., genetic, species, and ecosystem levels).
The different types of animals, plants and microorganisms that live in a forest represent an example of biodiversity.

Why are fossils important to developing a theory of evolution?
Answer:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms
Explanation:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms
The preserved remnants or traces of extinct animals, plants, and other organisms are known as fossils. Because they demonstrate that earlier life on Earth was distinct from the life observed today, fossils are crucial pieces of evidence for evolution.
What is evolution?According to the idea of evolution, modern life forms have evolved from more ancient ones.
The original theory suggested that this occurred slowly and gradually, but fossil evidence suggests that the process occasionally went wrong and engaged in some very bizarre experiments.
Therefore, they demonstrate that earlier life on Earth was distinct from the life observed today, fossils are crucial pieces of evidence for evolution.

Stickleback fish protect themselves from predators with a thick covering of brownish plates. They feed on
small aquatic organisms and are preyed upon by bigger fish like trout. In a certain lake, the number of
stickleback fish was documented over a period of 30 years. During this time, the clarity of the lake water
also changed.

the graph to support your answer. Using what you know about natural selection and adaptation, what
generalization can you make based on these changes?
Explanation:
scam fakeeee
just kidding the answer is
every time the differences will change because of the large fishes which kill the small ones and the fishes het big like in one big fish there will be 100 of small fishes like the megladon
during this blood also leaks and the colour of the lake changes
Answer:
In each instance, the variations in fish populations are subject to change due to the predation of larger fish on smaller ones. As a result, the surviving fish grow larger, akin to the manner in which the Megalodon can have hundreds of smaller fish within its body. This process can also result in the release of blood, which has the potential to alter the color of the surrounding water body.

If you throw a ball straight up into the air, when is the kinetic energy the greatest?
Question 4 options:
Right before you catch it after it falls back down.
When the ball reaches the highest point and stops briefly.
Half the distance on the path traveling back down.
Half the distance on the path traveling up in the air.
Half distence on the path traveling up in the air.
Explanation:
When the ball is on thr ground there and not moving there is no potential energy or kinetic energy, when the ball is tossed into the air it will reach maximum height which is determined by how much kinetic energy it has (air resistence is important however) when the ball reaches its velocitu is 0 and all of the energy in the system is potential energy, as the ball falls to the ground that potential energy is converted to kinetic energy
If a ball is thrown straight up into the air, the kinetic energy is greatest when the distance is half on the path travelling up in the air. Thus, the correct option is D.
What is Kinetic energy?Kinetic energy is the energy associated with the body which is under motion. Kinetic energy is directly proportional to the distance, mass and velocity of the object.
When the ball is thrown on the ground and is not moving then there will be no potential energy or kinetic energy as the height and velocity is zero when the object is on ground. When the ball is tossed into the air, it will reach maximum height which is determined by the kinetic energy it has and the air resistance when the ball reaches zero velocity and the greatest kinetic energy is observed when the body attains half of the total distance on the path.
Therefore, the correct option is D.

Observing one property is often the best way to identify minerals,
Rocks are the components that make up minerals.
Minerals can only be identified by their color and hardness.
Minerals are the components that make up rocks.
O Minerals are naturally occurring substances
Minerals are made of one element or one compound of elements
Answer:
The correct answers are 1) minerals are the components that make up rocks. 2) Minerals can only be identified that make up minerals. 3) Minerals are made of one element or one compound of elements.
Explanation:
I took the test. I got this question wrong but after submitting it, the lesson should me the correct answer.
The items that are true about minerals are:
Minerals are naturally occurring substances.Minerals are inorganic and homogeneous substances, which can be found on the surface of the Earth, formed in it naturally / spontaneously.
Minerals are made of one element or one compound of elements.Minerals are found in various forms in nature since they can be of a single element, such as gold, silver, copper, or a combination of elements, such is the case of some chemical compounds such as quartz, which is formed by silicon and oxygen.
Minerals are the components that make up rocks.A rock is a material that can be made up of a mineral or a combination of them, but its chemical composition is variable.
Therefore, we can conclude that a mineral is a substance produced by processes of inorganic nature which are made of one element or one compound of elements.

Describe why enzymes are important in all living organisms?
Answer:
Enzymes are important because they make the chemical reactions in cells happen quickly.
Enzymes, by speeding up biological reactions, ensure that all necessary activities in a cell can take place simultaneously and prevent one particular activity from overtaking the entire cell or organism. This is possible because enzymes allow chemicals to react more specifically with only certain substances rather than reacting indiscriminately with any number of different substances within cells.
The most famous example of this enzyme effect is when stomach acid reacts with pepsin that turns food into a liquid. The body then uses this liquid for absorption through the intestines where nutrients are then used throughout the body. It's important for people to have enough enzymes in order to digest their food fully however if

Maxine miles runs a marathon in 2 hours and 40 minutes. Most of the ATP for this activity is supplied by AEROBIC glucose breakdown. ATP is the energy coin of the cell.
Cellular respiration refers to the metabolic processes by which aerobic cells produce ATP by using the energy stored in the chemical bonds of foods (e.g., glucose) and oxygen.
Muscle cells can produce ATP by both cellular respiration (aerobic conditions) and acid lactic fermentation (anaerobic conditions).
Acid lactic fermentation is a less efficient pathway than cellular respiration, but cellular respiration is slower than fermentation, thereby muscle cells use this pathway (acid lactic fermentation) when there is not enough oxygen in the body.
