What is a Fossil? I am confused right now.
In a nutshell, fossils are the remains of plants
and animals from millions of years ago.
So, the answer would be C, the remains of a dead organism.
Fossils look like rocks with a design or picture in them
and the dead plant or animal becomes part of the rock.
Fossils usually form when a dead plant
or animal lies buried in the sand or the mud.
Answer:
The remains of a dead organism
Additional Information:
FossilA fossil is the mark or hardened remains of plant or animal that had existed thousands or millions of years ago.Some fossils such as leaves,shells or skeletons are preserved after the death of animals and plants.A fossil varies range from tiny microscopic to gigantic dinosaur bone in size.Most of the fossils are found in sedimentary rocks.

Explain the transcription and translation of fur color gene.
Answer:
Transcription of the fur colour gene involves the conversion of the gene that codes for the fur colour in the deoxyribonucleic acid of the animal to an ribonucleic acid template. While in translation, the ribonucleic acid template is converted to the required aminoacids which are linked up to form the protein that is expressed when the fur of the animal is to be determined.
Explanation:
In the process of transcription, the gene coding for fur colour in the animal found in in the deoxyribonucleic acid which houses all the genetic information of the animal is read in the ribonucleic acid format with adenine bases replaced with uracil instead of thymine. This format is then translated by the messenger ribonucleic acid per codon ( made up of 3 bases) into the protein responsible for fur colour until the stop codon terminates the transcription process. The polypeptide produced is then released and ready for expression.
Cancer cells are different because they don't enter the G - 0 phase and they are likely to do which of the following Your answer: a)fail to complete the S phase b) mutate during G1 phase c) repeat the cell cycle continuously d) die after completing mitosis
Answer:
c) repeat the cell cycle continuously
Explanation:
Cell division is a normal phenomenon for all cells as this is the way the cell reproduces and gets repaired in living organisms. However, some cells, due to mutation, keeps dividing and proliferating to form tumours. These cells are called CANCER cells. A normal cell undergoes cellular repair at certain checkpoints of the cell cycle. The checkpoints are necessary to determine a faulty cell and stop its division.
However, cancerous cells do not undergo any repair, which is why they do not enter the G0 phase as mentioned in the question. They keep on dividing out of control without death by repeating the cell cycle continuously.

Scientists who study the anatomy of the systems in the human body focus on the structure of the organ and organ systems of the body. So the correct option is D.
What is anatomy?Anatomy is a field of biological sciences that studies the description of body structure and their identification of living beings. Anatomy also studies the relationship of these structures with one another.
Gross anatomy is referred to the major body sections in a narrow sense after dissection. The body structures studied under gross anatomy are simply those that are big enough so that their observation does not need any kind of magnifying device.
Microscopic anatomy is the study of structures which can only be observed with the help of a microscope.
In all kinds of anatomical research, dissection is necessary because it's not really possible to study internal structures without opening them. The earliest record of the study of anatomy is from the Greeks, in fact, the word anatomy is derived from the Greek word ana temnein which means to cut-open.

F
Answer:
true
Explanation:
Recreational activities can cause an increase in erosion rates. So, the given statement is True.
What is Soil erosion?Soil erosion is defined as the removal or wearing away of the top layer of soil which is a form of soil erosion. This natural process is caused by dynamic activity of erosive agents, i.e. water, snow, ice, wind, plants and animals.
Erosion in recreational areas usually begins with vegetation removal as a result of activities such as walking, horseback riding, camping, motor vehicle use, mountain bike riding, and the development of visitor facilities. Stronger storms, higher river levels, and faster stream velocity can increase erosion.
Thus, Recreational activities can cause an increase in erosion rates. So, the given statement is True.

What happens when two parents with different traits have offspring why
Answer:
The answer is that the child will most likely look like half of one of the parent and the other half of the parent, like 50/50.
Explanation:
- The reason for this is each parent will pass only half of their gene to the child and the other half will either be from one of the parents or random (such as from their grandparents, parent's siblings, etc).
- However, sometimes other things can occur. For example, the child can look completely like one of their parents because that parent's genes are dominant.
For example, if you have parents, one with brown eyes, brown hair and the other one have blue eyes and blonde hair. There is a higher chance the child can come out looking like the parent with brown eyes and brown hair. The reason for this is blue eyes and blonde hair are recessive traits.
