Answer:
See the answer below
Explanation:
Prokaryotic cell: contain DNA, are surrounded by a cell membrane, were the first photosynthetic organisms on earth.
Eukaryotic cells: can be specialized for specific tasks in multicellular organisms, contain DNA, contain Nuclei, are surrounded by a cell membrane.
Prokaryotic cells are the earliest cells to be formed in the pre-oxygen earth. The photosynthetic prokaryotic cells released oxygen into the atmosphere during the process of photosynthesis and as such, other forms of cells were able to evolve. Prokaryotic cells lack a nucleus and membrane-bound organelles. Their DNA lies freely within the cytoplasm but the cell itself is surrounded by a cell membrane that controls the movement of substances in and out of the cell.
The eukaryotic cells evolved much later after the prokaryotic cell. It has both nucleus and membrane-bound organelles. The DNA is located in the nucleus and the cell is also surrounded by the cell membrane. The eukaryotic cells can aggregate together to form tissues, organs, or systems for a specific task in multicellular organisms.
Answer:
Prokaryotes.
1. Have dna.
2. Were the first photosynthetic organisms on Earth
Eukaryotes.
1. Have DNA
2. Have nuclei.
3. Are surrounded by cell membrane.
4. Can be specialized for specific tasks in multicellular organisms.
Explanation:
Prokaryotes are majorly unicellular organisms that have no membrane bound nucleus or organelles. They are the first photosynthetic organisms on Earth. They lack mitochondria and endoplasmic recticulum.
Eukaryotes are multicellular organisms that have membrane bound nucleus or organelles. They lack chloroplast and they gave mitochondria and Endoplasmic recticulum.

Which of the following groups of organisms uses sunlight to convert carbon dioxide and water into sugar and oxygen?
a. producers
b. decomposers
c. carnivores
d. herbivores
The group of organisms which uses sunlight to convert carbon dioxide and water into sugar and oxygen are producers. Thus, the correct option is A.
What are Producers in the ecosystem?Producers are any kind of green plants present in the ecosystem. Green plants make their own food by using the sunlight (solar energy) and carbon dioxide gas from the atmosphere with the energy to make sugar. The plant uses this sugar (carbohydrate), also called as glucose to make many different products, such as wood, leaves, roots, and bark.
This process through which plants produce their food is called photosynthesis. Photosynthesis occurs only in the plants which have chlorophyll pigment (chloroplast).
Therefore, the correct option is A.

is chlorine gas a polar or nonpolar covalent bond
Pretty sure its non-poaler (definitly sure) :)
Answer:
Explanation:
Covalent bonds are very similar to chlorine gas. Which is also known as (C12). Both of these atoms share and hold tightly onto their electrons.
The hydrogen atom has a positive charge becauseIt cannot hold as tightly to the negative electron bones. Covalent molecules with this type of uneven charge distribution are polar.

There are approximately 259 hectares per square mile. How many deer could a square mile of forest of mature American chestnut trees support for a year if they were the only organism consuming their nuts?
Answer:
25 deers
Explanation:
According to studies conducted by wildlife experts, a single deer needs roughly 25 acres of land in order to survive comfortably. Therefore we first need to find out how many acres are in a hectare, which based on a quick search online we see that 25 acres equal 10.11 hectares which is what a single deer needs to survive. Now we divide the total amount of hectares by the hectares a single deer needs in order to find out how many deers can survive on this total amount of land.
259 / 10.11 = 25.618
Finally, we can see that the 259 hectares can maintain roughly 25 deers.

Part1: Compare the relative concentrations (amount of GtC) of at least six (6) components of the carbon cycle
(e.g. The ____ has less GtC carbon than the ______ .)
Part 2: Explain how the total amount of matter is conserved during the carbon cycle.
hint-the earth is a closed system
Answer:
Explanation:
PART 2 : The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle.
Because elements are neither created nor destroyed under normal circumstances, individual atoms that compose living organisms have long histories as they cycle through the biosphere. In this depiction, a carbon atom moves from coal buried beneath the Earth's surface to a power plant and into the atmosphere. It eventually dissolves in water and is taken up by an algal cell, where it is then consumed by a copepod.
