fossils at used to determine what
Answers
Answer:
fossils are used to tell how long they lived what did they eat how they died habitat what they eat
Explanation:
The fossils present in a rock exposure or in a core hole can be used to determine the ages of rocks very precisely. Detailed studies of many rocks from many places reveal that some fossils have a short, well-known time of existence. These useful fossils are called index fossils.
Answer:
Fossils have been used by scientists to determine the dates of rock layers (or strata) that were laid down in succession hundreds of years ago. However, the accuracy and precision of this method depend on several conditions, such as depth, lithology, thickness and abundance of the fossils in that rock.

3. Explain the digestion of a bite of mixed feed in a cow and a pig. Do this in a stepwise progression beginning with prehension and ending in defecation.
Answers
Answer and Explanation:
The process which our body uses to absorb and breakdown nutrients stored in food are called digestion. The cow has a unique digestive process to break down the food. It has four stomachs. When a cow takes a bite of food, it chews the food very little and then swallow. The reticulum and the rumen are the first two cats' stomach; the unchewed food travels to these stomachs—the food stored in this two stomach until later. Cow rests when this process of eating is completed. Later, cow coughs up unchewed food bits named cuds and chewed it thoroughly before swallowing again. The omasum and abomasum are the third and fourth stomach of a cow. The cuds then go to them, where it is completely processed. Some digested food enter in the bloodstreams, while rest goes towards the nourishment of cow. In the pig, the digestion of food starts in the mouth. Food is masticated into small pieces and mixed with saliva, then swallowed. After swallowing the food, it moves down into the stomach. In the stomach, food mixed with enzymes which help in the breakdown of the food. The food enters in the small intestine, where most of the digested food is absorbed. Then the food enters the large intestine. Large intestine absorbs salts and water from undigested material and get rid of left-over.
Which of the following statements correctly describes the difference between the semiconservative model of DNA replication and the conservative model of DNA replication?
A.The semiconservative model states both strands of DNA remain together after replication and the conservative model states both strands separate.
B. The semiconservative model states single-stranded DNA strands are used as a template strand to create newly synthesized DNA strands and the conservative model states only one side is used as a template.
C.The semiconservative model states the DNA strands are randomly paired with a newly synthesized DNA strand and the conservative model states only new strands are paired.
D.The semiconservative model states the two original DNA strands separate and are used as template strands to create newly synthesized DNA strands and the conservative model states the two original strands remain together.
Answers
Answer: B.
Explanation: As the DNA double helix is unwound by helicase, replication occurs separately on each template strand in antiparallel directions. This process is known as semi-conservative replication because two copies of the original DNA molecule are produced. Each copy contains one original strand and one newly-synthesized strand.
The statement that correctly describes the difference between the semi-conservative model of DNA replication and the conservative model of DNA replication is as follows:
The semi-conservative model states single-stranded DNA strands are used as template strands to create newly synthesized DNA strands and the conservative model states only one side is used as a template.Thus, the correct option is B.
What is DNA replication?DNA replication may be defined as a type of biological process that deals with the synthesis of two identical replicas of DNA from one original DNA molecule during cell division.
The semi-conservative model of DNA was proposed by Watson and Crick. This model implies that each double helix of DNA is composed of one new and one old strand.
In semi-conservative replication, the parental double helix is half conserved and each parental single strand remains intact. While in the conservative model of DNA replication, the entire original form of the DNA double helix function as a template and synthesize a new double helix.
Therefore, the correct option for this question is B.

An image of a mountain with three circles going up the side of it. The lowest circle is filled with many, smaller circles. The middle circle has fewer circles that are farther apart. The highest circle has the fewest circles that are the farthest apart.
What do the molecules in the circles model regarding altitude?
A. Air pressure increases at higher altitudes.
B. Air density decreases at higher altitudes.
C. There is a greater gravitational pull on air molecules at higher altitudes.
D. Temperature has a decreasing effect on air molecules at higher altitudes.
Answers
Answer:
B. Air density decreases at higher altitudes
Explanation:
Since air is compressible, air from higher altitudes will compress air from lower altitudes. As a result, air density at lower altitudes will be greater than air density at higher altitudes. Air particles at the highest altitudes, not being acted upon by air above it, will be more spread out.
Compare the two DNA sequences. How many of the DNA codons (sets of three nucleotide bases) are different between the two sequences?
options:
A: 1
B: 4
C: 3
D: 2
Answers
2 DNA codons are different between the two sequences. So, the correct option is (D).
What are Codons?Codon is defined as a sequence of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid. Some codons signal the beginning or end of translation, called start or stop (or termination) codons.
Codons are present on an mRNA or DNA. which are sequences of three nucleotides that code for a specific amino acid while the anticodons are present on tRNA (transfer RNA) molecules that help to transcribe or bring about amino acids in mRNA during the translation process.
The three-letter nature of codons that means the four nucleotides found in mRNA — A, U, G, and C which can produce a total of 64 different combinations.
Thus, 2 DNA codons are different between the two sequences. So, the correct option is (D).

Acid rain contains chemicals that can break rocks. Which describes this interaction?
A) hydrosphere and geosphere
B) geosphere and biosphere
C) biosphere and atmosphere
D) atmosphere and hydrosphere
E) hydrosphere and biosphere
Answers
The correct answer is A) Hydrosphere and geosphere
Explanation:
Planet Earth comprises different systems or spheres. Moreover, these systems often overlap or interact. This occurs in the case of acid rain that breaks rocks. Acid rain as well as other forms of water such as snow, hail, liquid water in rivers, etc. belongs to the hydrosphere, which includes all water (H2O) on Earth. On the other hand, the rocks belong to the geosphere, which comprises all the surface and materials in it such as rocks or minerals. This implies in this context the rocks from the geosphere interact with the rain of the hydrosphere.
Explain why organisms are more likely to be well preserved in mud than in sand? Justify your response in
two or more complete sentences in the essay box below.
PLS I NEED HELP ASAP!!!
Answers
Answer:
Explanation:
Organisms are well preserved in mud because mud has high water holding capacity. It retains water and does not allow oxygen flow which can destroy the remains of organisms. There are some microbes that preserved whose growth are enhanced in water related environment like mud.
But sand cannot retain or hold water. It drains it off and all oxygen bearing water to flow which enhance decay compared to mud. It can't preserve organisms because of the above reasons.
Answer:
Organisms are more likely to be well preserved in mud than in sand because sand allows oxygen that has water(oxygen-bearing water) to flow through it. This type of oxygen speeds up decay. Mud does not have this oxygen so it prevents the flow of water, and keeping oxygen away means it slows decay of the buried organisms.
