(b) Had soft parts
(c) Were generally large
(d) Lived in a narrow geographic area
Answers
Answer:
A.) Are extinct
You should mark me brainliest because I think I'm cool
Index fossils are usually defined as those fossils that were present on earth for a very short period of time. They were very broadly distributed in almost all parts of the world. They were comparatively smaller in size and comprised of hard parts that were preserved under favorable conditions which are found at many places in the present. These are extinct species. For example, trilobites and ammonites.
These index fossils are very useful because it helps in determining the age of the fossils as well as rocks by applying the radioactive dating method.
thus, the correct answers are options (1), (2), and (4).
the difference between prokaryotic and eukaryotic gene regulation
Answers
Answer:
READ THIS
Explanation:
To understand how gene expression is regulated, we must first understand how a gene codes for a functional protein in a cell. The process occurs in both prokaryotic and eukaryotic cells, just in slightly different manners.
Prokaryotic organisms are single-celled organisms that lack a cell nucleus, and their DNA therefore floats freely in the cell cytoplasm. To synthesize a protein, the processes of transcription and translation occur almost simultaneously. When the resulting protein is no longer needed, transcription stops. As a result, the primary method to control what type of protein and how much of each protein is expressed in a prokaryotic cell is the regulation of DNA transcription. All of the subsequent steps occur automatically. When more protein is required, more transcription occurs. Therefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level.
Eukaryotic cells, in contrast, have intracellular organelles that add to their complexity. In eukaryotic cells, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into the cytoplasm, where ribosomes translate the RNA into protein. The processes of transcription and translation are physically separated by the nuclear membrane; transcription occurs only within the nucleus, and translation occurs only outside the nucleus in the cytoplasm. The regulation of gene expression can occur at all stages of the process (Figure 1). Regulation may occur when the DNA is uncoiled and loosened from nucleosomes to bind transcription factors (epigenetic level), when the RNA is transcribed (transcriptional level), when the RNA is processed and exported to the cytoplasm after it is transcribed (post-transcriptional level), when the RNA is translated into protein (translational level), or after the protein has been made (post-translational level).
Answer:
Prokaryotic gene expression is primarily controlled at the level of transcription. Eukaryotic gene expression is controlled at the levels of epigenetics, transcription, post-transcription, translation, and post-translation.

Summarize the process of sexual reproduction and explain how variations of inherited traits can increase or decrease an organism’s chance of survival
Answers
Answer:
Explanation:
A Human cell has 46 chromosomes. (I’ll use humans to keep things simple). In sexual reproduction both humans have 23 chromosomes, in their sex cells. (Men have 23 in a sperm and women have 23 in an egg cell). These half cells merge to create 1 unique cell, that has characteristics of both male and female. The cells multiply and then a baby is born with a unique set of genes. These cause variations, and remember these variations can carry from generation to generation. As for how variations can increase a chance for survival, variations allow unique gene sets to be made, so that in case of a disease (in this case I’ll use a disease, but it could also include harsh environmental conditions), these unique gene sets may give an individual natural immunity to the disease. How can a variation decrease an organisms chance for survival? Well, s there are many ways that a unique gene set can make it difficult to survive. For example a genetic disease your family has had a history with. These diseases include, but are not limited to, cancer, diabetes, and schizophrenia.

D. Discarding data that does not fit with your personal expectations.
Explanation:
One of the ways in which bias can be introduced into an experiment is by discarding data that does not fit with one's personal expectations.
Bias in an experiment is the process whereby scientists alter the results of their experiment to achieve their own expected results.
Anomalous values defined by one's expectation can make an experiment highly biased. A scientist is supposed to be objective in their experimental approaches.What predication can you make about future levels of carbon dioxide CO2 in the atomphere

One side of the water molecule has a positive charge, while the other side has a negative charge. What do the charges indicate about the molecule?
Answers
Answer:
That its a nuetral
Explanation:
In the given case of water molecule, the charges shows that it is a polar molecule.
What is a polar molecule?It is a molecule in which one terminal of the molecule is slightly positive and the other terminal is slightly negative. In the case of water molecule, the unequal sharing of electrons provides the molecule with a slight negative charge close to its oxygen atom and a slight positive charge close to its hydrogen atoms.
When a neutral molecule, possesses a positive region at one terminal and a negative region at the other, it is considered as a polar molecule. The molecules of water attract each other on the basis of the positive end of one water molecule and the negative end of the other molecule of water.
Thus, the charges shows that it is a polar molecule.

An animal cell with a 30% salt solution is placed in a beaker with a 20% salt
solution. Which is the correct conclusion if the cell remains in the beaker for an
extended period of time?
Answers
Answer:
the animal cell will burst
Explanation:
If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.
Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.
Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.

Which effect does the sun's energy have on a comet?
A. It causes the comet to form a bright tail.
B. It causes the core of the comet to melt.
C. It causes the comet to turn toward earth.
D. It causes the comet to break apart.
Answers
Answer:
The answer is B because the sun melts the core of the comet
The sun's energy causes the comet to form a bright tail. The correct answer is A.
When a comet approaches the Sun, the Sun's energy causes various effects on the comet.
As the Sun heats up the comet, it causes the icy nucleus of the comet to vaporize and release gas and dust into space.
This process is known as outgassing. The released gas and dust form a glowing envelope called a coma around the nucleus.
Additionally, solar radiation and solar wind push the released gas and dust away from the comet, forming a glowing tail that points away from the Sun.
So, the correct option is A.

The effect of temperature on these molecules are ;
ATP will increase NADPH will also increase while Sugars will decreaseATP ( Adenosine triphosphate ) is the molecule in cells which stores energy in cells while transferring the energy needed within cells as well. When the temperature of a cell is raised above the required temperature this molecule will also increase in response.
NADPH is an electron donor which is found in organisms, it also provides the reducing power for certain reactions in the organism ( anabolic ) and the gathering of NADPH oxidase. increases as the temperature of the organism increases.
Hence we can conclude that as temperature increases , ATP will increase , NADPH will increase while Sugars will decrease.

When she looked at the cells under a microscope, she noticed that the cells in the leaf shrunk. Which statement best explains what caused the cells to shrink?
The hypertonic solution caused the water in the cell to move from the cytoplasm into the nucleus.
The salt moved from the hypertonic solution into the cell and chemically bonded with the water.
The salt within the cell moved through the cell membrane into the solution with the higher salt concentration.
The water within the cell moved through the cell membrane into the solution with the lower water concentration.
Answers
Answer:
The water within the cell moved through the cell membrane into the solution with the lower water concentration.
Explanation:
According to this question, a scientist removed the leaf of a plant originally grown in a freshwater aquarium and placed it in a hypertonic solution containing 8% salt. Firstly, A HYPERTONIC SOLUTION is that solution which contains a higher solute concentration than that of the intracellular environment.
Due to this concentration gradient i.e. difference in concentration, OSMOSIS process will be triggered. Osmosis is the movement of water from the region of low solute concentration (the leaf cells) to a high solute concentration (the salt solution) via a semi-permeable membrane (cell membrane).
Therefore, osmotic process causes water to move from the leaf cells into the salt solution via the cell membrane. hence, causing the cells of the leaf to shrink.
