Answer:
Life on Earth goes back almost 4.1 billion years, but photosynthesis as characterized by cyanobacteria only appeared around 3.5 billion years ago (Ga). Since life on Earth predates photosynthesis, the exploration of this deep-water environment that lacks any source of light could provide information on what those life forms looked like.
Explanation:
This was the answer on edge
The major reason for exploring the mid-Cayman ridge is to provide
information on what those life forms looked like.
What is Photosynthesis?This is the process in which plants manufacture their food in the presence
of sunlight and other compounds.
The mid-Cayman ridge which is present in a deep water environment has
lacks any source of light has some life-forms present. The exploration was
to find out the type of life forms present and how they appear.

Molecules of DNA are composed of long chains of?
two long polynucleotide chains
A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together
Molecules of DNA are composed of long chains of nucleotides.
What are nucleotides?Nucleotides are the building blocks of DNA and RNA adenine (A), thymine (T), guanosine (G), and Cytosine (C. In RNA, uracil (U) is present instead of thymine.
The pentose sugar is the ribose sugar in RNA and deoxyribose sugar in DNA. In deoxyribose sugar, oxygen is absent from the 3' carbon.
Phosphate groups are attached through the 5-C of pentose sugar by an ester bond. One polynucleotide chain is formed when the phosphate of one nucleotide forms a phosphodiester bond with the sugar of another nucleotide.
A double-stranded structure is formed by base pairing between nucleotides. The adenine binds to thymine by two hydrogen bonds and guanine binds to cytosine by three hydrogen bonds.
Therefore the molecules of DNA are composed of long chains of nucleotides.

What is the energy source that allows photosynthesis to occur?
Answer:
[tex]\boxed {\boxed {\sf The \ sun }}[/tex]
Explanation:
Photosynthesis is a special process that certain organisms (plants, algae, and some bacteria) undergo to create "food".
This turns light energy, carbon dioxide, and water into glucose and oxygen. The glucose becomes the food for the organism, because it is turned into ATP during cellular respiration. The ATP is energy that fuels the processes, like growth, repair, and transport.
This process occurs because of the sun. It provides the light energy needed for the reaction. Organelles inside of the cells, called chloroplasts, contain a pigment (chlorophyll) that captures this energy.

Identify the natural processes that occur on the earth's surface to make and destroy rocks.
Answer:
You learned about the three rock types: igneous, sedimentary, and metamorphic. You also learned that all of these rocks can change. In fact, any rock can change to become any other type of rock. These changes usually happen very slowly. Some changes happen below Earth’s surface. Some changes happen above ground. These changes are all part of the rock cycle. The rock cycle describes each of the main types of rocks, how they form, and how they change.
The figure below shows how the three main rock types are related to each other (Figure below). The arrows within the circle show how one type of rock may change to rock of another type. These are the processes that change one rock type to another rock type.

An arrow is shown from the sun towards the left tree marked A. The sun is marked B. There is an arrow from the air above the clouds, marked C, towards the left tree. An arrow from a location close to the ground marked D points towards Dead Organisms, which is a label under the animal. An arrow marked E points from the right tree straight up to the clouds. An arrow marked F points from the animal straight up to the clouds. An arrow marked G points from the factory towards the air above the clouds, C. There is an arrow pointing from the air to the lake labeled Carbonates in Water, an arrow pointing down from dead organisms to Fossils and Fossil Fuels, and an arrow from Fossils to the factory.
Part 1: What is happening at location G?
Part 2: Which type of energy transformation is taking place at this location?
Part 3: Justify why this process is a recycling of carbon in the carbon cycle.
Use complete sentences to explain your answer.
Answer:
This is too difficult to read and understand... if you had a diagram I could be able to help more, but I can't figure out exactly what your asking... all I know is part A is CO2 being released into the atmosphere...
Hope you have a great day and if you have a diagram let me know.. I'd love to help :D
Answer:
Part I
At location G, the process of combustion is taking place where hydrocarbon or organic carbon from the fossil fuel is burnt in the presence of oxygen to produce carbon dioxide and water as the products.
CxHy = CO₂ + H₂O
Part II
At point G there is no transformation of energy since during the process of combustion energy will still be stored in form of chemical energy in the bonds of carbon Iv oxide and the water produced during the reaction.
Part III
The process shows recycling of carbon in the carbon cycle. This is because carbon from living organisms is cycled to non living organisms. When plants and animals die and are buried deep in the ground, they are then slowly converted to fossil fuels which contain organic hydrocarbon compounds including petrol, kerosene and other compounds. Then the fossils are used in the industries and undergoes combustion releasing carbon iv oxide which is then released to the atmosphere and used by the plants and animals. The process starts once again.

Answer:
1. Circulatory system is made up of your heart, arteries, veins and capillaries.
2. There isn't a photo attached. But Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle. Different tissues are in turn grouped together to form larger functional units, called organs.

Answer:
Once assembled, what is the key to a protein's unique function? The manner in which proteins fold is the key to their function
The endoplasmic reticulum is an important region where protein folding occur. Because proteins need to be appropriately folded into distinct structures, this is an essential biological function.
What is importance of protein folding?Proteins that are misfolded or are unfolded improperly impart to the pathophysiology of many illnesses.
Protein folding is a highly delicate process that is regulated by a variety of external stimuli, such as temperature, pH, chemicals, molecule crowding, electric and magnetic fields, and temperature.
These elements affect a protein's capacity to fold into the appropriate functional forms.
Therefore, Protein folding give unique properties to protein functions.

How is the earthworm limited by being a skin breather?
Answer:
Earthworms need oxygen just like humans, but they don't have lungs like we do. They have a special skin that allows them to “breathe” oxygen right through it. ... This means the amount of oxygen inside the earthworm will always be less (lower concentration) than the area outside of the earthworm (higher concentration).

What are the locations and end products for the processes of transcription and
translation?
Answer: The transcription is the process of production of mRNA molecules from each separate strand of DNA individually and the translation is the production of protein by using the genetic information present in the mRNA.
Explanation:
The process of transcription occurs inside the nucleus of the cell in the eukaryotic cell typically not in prokaryotic cell whereas the translation process occurs in the cytoplasm with the help of ribosome.
mRNA is the product of transcription whereas the polypeptide chain of amino acids is the production of the translation in which further forms the protein.
