Answer:
D)clues about the past climate of Earth
Explanation:
The fossil record certainly has gaps, mostly because the conditions required to create fossils have been rare ever since life began on Earth. A very small percentage of animals that have lived and died ever became fossils. Thus, many pieces of the puzzle are missing; some will never be found.

Will give brainliest Lions are the predator that most often hunt both wildebeest And Buffalo, what do you predict is happening to the lion population between 1960 and 1975?
Answer:
Fewer than 500 lions remain in West Africa, the study estimated. The team and a panel of lion experts used the savannah data to refine estimates of lion populations, which had ranged between 20,000 and 40,000 across Africa. Their estimate: 32,000 lions remain, down from an estimated 100,000 in 1960.
In which of the following ways is DNA replication different from DNA transcription? (4 points)
New cells can be created only after transcription has taken place.
Replication results in mRNA strands, while transcription creates new DNA.
Transcription happens outside the nucleus, and replication happens inside the nucleus.
Thymine is used in replication, while uracil is used in transcription.
Answer:
Transcription copies the DNA into RNA, while replication makes another copy of DNA. Both processes involve the generation of a new molecule of nucleic acids, either DNA or RNA; however, the function of each process is very different, with one involved in gene expression and the other involved in cell division.Explanation:
So,my answer is,transcription happens outside the nucleus,and replication happens inside the nucleus.

What is the defining characteristic of an acid?
Answer:
Acid in chemistry has distinguishing properties as a substance. Acidic compounds are acidic; they react with paper, bases and metals; they conduct electricity; they have a pH of less than 7. They can generate electricity. Based on reactivity, conductivity and pH levels, an acid can be categorized as strong or weak.
Explanation:
The defining characteristic of an acid is when dissolved in water, acids are sour in taste, conduct electricity and react with metals to produce hydrogen gas.
What is an acid?
"An acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis)."
What are the types of acid?
Usually acids can be divided into three major types:
binary acid, oxyacid, carboxylic acid.What are main characteristics of acid?
The main characteristics of acid are:
Aqueous solutions of acids are electrolytes, meaning that they conduct electrical current.Acids have a sour taste.Acids change the color of certain acid-base indicates. Acids react with active metals to yield hydrogen gas.Acids react with bases to produce a salt compound and water.To know more about acid here https://brainly.com/question/14072179

why would plants and animals store carbohydrates
Answer:
Why would plants store their energy as carbohydrates and not as fats, if fats are a more efficient energy store? Plants synthesize glucose from carbon dioxide, animals ingest carbohydrates in their diet and break them down into monosaccherides.
A student drew the following flowchart in her notes.
Crushing - Sizing → Concentrating - Dewatering
What does the process show?
A. Crystallizing magma
B. Blending coal
C. Processing minerals
D. Refining crude oil
Answer:
processing minerals
Explanation:
The flowchart which is shown here include: Crushing→ Sizing→ Concentrating→ Dewatering. This process is showing processing minerals. Thus, the correct option will be C.
What is Mineral processing?Mineral processing is the process which includes separation of the commercially valuable minerals from their ores in the Earth's crust. Depending on the processes which are used in each instance, it is often also known as the process of ore dressing or ore milling.
The profitability of an ore or a mine is based on how much concentrate of the desirable mineral can be extracted or mined from the ore. As a result of this, mineral processing can be designed to yield the maximum amount of mineral concentrate which is possible before products hit the market.
Therefore, the correct option will be C.

Question 3 options:
their soil and plants can filter and clean water
they can transfer pollutants
they cause precipitation and acid rain
they cause floods
Answer:
A. their soil and plants can filter and clean water
and
B. they can transfer pollutants
Explanation:
i took the same quiz and got an A! :D
Watersheds can transfer pollutants and their soil and plants can filter and clean water. So, the correct option is A and B.
What are Watersheds?Watershed also known as drainage basin defines an area of land where all flowing surface water converges at a single point, such as a river mouth, or flows into another body of water, such as a lake or sea.
The size of a watershed is defined on several scales referred to as its Hydrologic Unit Code (HUC) based on the geography most relevant to its specific area. A watershed may be small, such as a minor inland lake or a county.
Some watersheds cover thousands of square miles that includes rivers, streams, lakes, reservoirs, and underlying groundwater hundreds of miles inland. These can transfer pollution causing agents and clean the water.
Thus, watersheds can transfer pollutants and their soil and plants can filter and clean water. So, the correct option is A and B.

As a person exercises, this causes several body systems to work together. For 2 points each, answer the following questions: 1. Define organ system and what they are made up of to be able to do specific functions 2. Identify TWO organ systems (other than the nervous system) that would be involved in exercise. 3. Explain how the NERVOUS system would be involved in the exercise.
Answer:
The parasympathetic nervous system conserves energy as it slows down heart rate, increases intestinal and glandular activity, and relaxes the sphincter muscles of the gastrointestinal tract. It gets the nickname "rest and digest" for doing exactly so. Typically most active when sleeping, however is also the explanation for post-prandial fatigue, or being tired after eating (especially a large meal).
Explanation:
Define organ system and what they are made up of to be able to do specific functions An organ system is made of a few organs that perform multiple functions.
Identify TWO organ systems (other than the nervous system) that would be involved in exercise. parasympathetic nervous system
Explain how the NERVOUS system would be involved in the exercise.The peripheral system allows the brain and spinal cord to receive and send information to other areas of the body, which allows us to react to stimuli in our environment.The peripheral nervous system itself is divided into two parts: the somatic nervous system and the autonomic nervous system.Each of these components plays a critical role in how the peripheral nervous system operates.
Motor neurons: Also called efferent neurons, motor neurons carry information from the brain and spinal cord to muscle fibers throughout the body. These motor neurons allow us to take physical action in response to stimuli in the environment.
Sensory neurons: Also called afferent neurons, sensory neurons carry information from the nerves to the central nervous system. It is these sensory neurons that allow us to take in sensory information and send it to the brain and spinal cord.
Data from embyros can be used to help establish evolutionary relationships. True or false
Answer:
True
Explanation:
The study of the formation and development of the embryo is very useful in evolutionary biology in order to determine similarities derived from a common ancestor (i.e. homologies). In consequence, embryology is a discipline used to establish relationships between species and higher taxa. For example, vestigial organs and/or tissues (e.g., tails in humans) can be observed in the embryos during the first stages of development. In this regard, embryology has been an important aspect of the evolutionary theory proposed by Darwin (1859) by evidencing the process of species radiation from their ancient ancestors.
