Why do paleontologist study fossils ?
Answer:
Paleontologists study fossils so that we can understand the evolution's from past species to the current ones. It also opens a window to discovering exactly how long earth has been around by finding out the age of the fossil itself. Though paleontology has been in the decline recently, and i'm sure we haven't found out all we need to know from these fossils.

in the blank circle, draw the moon phases we would see if we were on Earth in the diagram and then write the name of that moon phase on the blank line
Answer:yThe Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. ...

1.An increase in the population of an organism would most likely be associated with which of the following?
A.an increase in animals that prey on an organism.
B.A decrease in necessary resources.
C.An expansion of suitable living space.
D.A series of severe weather events in the habitat.
Answer:
a series of severe weather events in the habitat
An increase in the population of an organism would most likely be associated with a series of severe weather events in the habitat. The correct option is D.
What is the population?A collection of creatures from the same species that can interact to create fertile progeny. It is on a level above organisms but below the ecosystem and community.
An ecosystem is a level of organization where several communities of various species and the associated abiotic elements interact. It is the place where different population interacts with each other.
A biosphere and a biome are larger organizational levels than this one. Communities are levels of the organization where various populations coexist and engage in social interactions.
Therefore, the correct option is D. A series of severe weather events in the habitat.

The energy that fuels food webs begins as light energy from the sun. True or False
Answer: i think its true. ( based of information i got)
Explanation: The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs. also A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.

Which of the following statements about the process of science is accurate?
A. Science does not use evidence and data collected to advance our understanding of natural and supernatural phenomena.
B. Science attempts to solve a problem by evaluating the plausibility of only one solution without considering other possible explanations.
C. Science is a systematic method of procedures designed to answer questions by evaluating evidence.
D. Science can answer all questions regarding the human experience and personal values.
Answer:
C
Explanation:
The correct answer would be that science is a systematic method of procedures designed to answer questions by evaluating evidence.
Science is generally defined as man's way of obtaining knowledge about his natural environment through the evaluation of evidence available to him. Science follows a laydown procedure to obtain evidence through data collection, analyze such, and arrive at reasonable conclusions. This laydown procedure is referred to as the scientific method.
Hence, that science does not use evidence and data collected to advance the understanding of natural and supernatural phenomena is an antithesis to what science represents.
Science only arrive at conclusion after evaluating all available evidence associated with a phenomenon. That it attempts to solve a problem by evaluating the plausibility of only one solution without considering other possible explanations is, therefore, not true.
Science continuously seeks knowledge in order to understand the natural world. Hence, while science has been able to answer several questions about man and his natural world, several questions still have their answers pending. That science can answer all questions regarding the human experience and personal values is, therefore, far from being true.
The only accurate option that describes science is C.
The best description of science is that science is a systematic method of procedures designed to answer questions by evaluating evidence.
What is science?Science is defined as the process by which man obtain knowledge about his natural environment through observation and critical evaluation of facts and evidences in order to arrive at a conclusion.
The scientific method is as follows;

what is the base-pair rule for a DNA strand matching an RNA strand?
Explanation:
The base pairing of guanine (G) and cytosine (C) is just the same in DNA and RNA. So in RNA the important base pairs are: adenine (A) pairs with uracil (U); Guanine G() pairs with cytosine (C).
The Chargaff rule only holds true for DNA. Base pairing doesn't take place since RNA is single-stranded. Consider a DNA strand.
What make base pair unique in DNA and RNA?Compare the two DNA strands' base-pair rules to this one. Since uracil is absent from DNA, T and A complement one another. In contrast, T bonds with A and A bonds with U in a DNA/RNA match.
Important: It serves as the foundation for base pairing. This rule can be used to both determine the DNA strand length and if a base is present in the molecule.
Adenine and thymine are always equal, and cytosine and guanine are also always equal, allowing us to calculate the percentages of each base.
It assists in figuring out the makeup and structure of DNA in various species. It is constant within a species.
Therefore, the base-pair rule for a DNA strand matching an RNA strand.

bond forms between a hydrogen atom with a partial positive charge on one
molecule and another atom, such as oxygen, with a partial negative charge on an adjacent molecule.
Answer:
Due to difference in the values of electronegativities.
Explanation:
A covalent bond is formed between hydrogen atom with a partial positive charge on it and another atom, such as oxygen, have a partial negative charge on an adjacent molecule. This is because of the difference in the values of electronegativities. The hydrogen atom has lower electronegativity value as compared to oxygen so the shared pair of electron is slightly attracted by oxygen atom towards itself and formed partial positive charge on hydrogen and partial negative charge on oxygen atom.

1. Suppose you lived over 100 years ago and you had a whole bowl of
fresh milk but only one cup of yogurt left. Describe how you might
make more yogurt?
Answer:
Lactic Acid Fermentation
Explanation:
Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. Lactate, which is just the deprotonated form of lactic acid, gives the process its name. The bacteria that make yogurt carry out lactic acid fermentation, as do the red blood cells in your body, which don't have mitochondria and thus can't perform cellular respiration.

6. Cells require molecules that cannot simply pass through the cell membrane. Explain how the cell can use proteins to transport these molecules across the cell membrane.
.
Explanation:
1)The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails.
2) simple diffusion across the cell plasma membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down the concentration gradient is , by simple diffusion.
3) some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic or however, because they are charged the polar, they can't cross the phospholipid part of the membrane without help .
4) during fission a copy of the DNA is made and attached to the cell membrane as well. As this cell elongate in preparation for fission, the two DNA copies are pulled apart two opposite ends of the cell. New membrane material is deposited between the two ends of the cell, and a new wall grows between them .
