How is photosynthesis and cellular similar, and how are they different?
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
What kind of molecules were formed by abiotic synthesis? How did they form?
Answer: Abiotic processes synthesized small organic molecules, such as amino acids and nucleotides. These monomers were joined into polymers, including proteins and nucleic acids. Polymers were packaged into “protobionts,” droplets with membranes that maintained an internal chemistry distinct from their surroundings.

He walked 5 units south and met his friend Joshua. After that, he walked 2 units east and there he bumped into his friend Ethan.
At what location on the coordinate grid did Sam meet Ethan?
OA. point (-3,5)
B. point (-1,-3)
Oc.
point (-3,-5)
O
D. point (-3,-1)
Answer:
(-1,-3) on the coordinate grid.
Explanation:
The location from where Sam started his morning walk is 3 units to the left and 2 units up from the origin. This location is indicated by the point (-3,2).
He walked 5 units south and met his friend Joshua.
So, find the point that is 5 units to the south of point (-3,2). Distances north and south on the map represent a change in the y-coordinate. Moving 5 units to the south on the map from point (-3,2) places the new location at point (-3,-3).
Sam then walked 2 units east, where he met his friend, Ethan.
So, find the point that is 2 units to the east of point (-3,-3). Distances east and west on the map represent a change in the x-coordinate. Moving 2 units to the east on the map from point (-3,-3) places the new location at point (-1,-3).
So, Sam met Ethan at the location indicated by point (-1,-3) on the coordinate grid.

A community in Florida wants to minimize the impact that cane toads have on the local ecosystem. Which of the following should they identify as part of defining the problem?
A.
solutions that are likely to be effective for controlling the cane toad population
B.
methods that have been used to control cane toads in Australia
C.
ways to raise money to support their efforts
D.
the predator populations that eat cane toads
Answer:
B
Explanation:
It isn't D because Cane toads have no natural predators, and it isn't C because there isn't a solution, but B offers a solution that would work since they share some of the same environments.

If round pea shape is dominant to wrinkled pea shape, which of the following genotypes
would produce the wrinkled phenotype?
A.RR
B.Rr
C.rr
Answer:
C. rr
Explanation:
The dominant genotype will always be denoted by the capital version, or in this case R.
The round pea shape is dominant to the wrinkled pea shape, which means that, in the Punnett Square, the combinations of RR, Rr, rR, will all come out to be round pea shape.
The last box, rr, would be the one that gives the wrinkled phenotype.
In this case, by ratio, wrinkled phenotype show up 25%
by ratio, round phenotype show up 75%.

a. Describe the endosymbiotic theory. Explain how chloroplasts are similar to prokaryotic cells.
b. Provide observations and evidence that supports the theory.
Answer:
The endosymbiotic theory was eukaryotes that evolved to prokaryotes then to other organelles. Chloroplasts are similar to prokaryotic cells because they have a double membrane structures and more. Things that support this theories can be like I said, double membrane structures which both have and circular DNA and bacteria ribosomes too.
Explanation:
:3
Answer:
The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.
Explanation:
The exterior structure similar to bacterial cell walls" IS NOT an evidence in favour of the endosymbiotic theory. Both mitochondria and chloroplasts are double membrane bound.
Explanation:
Both the organelles mentioned in your question, are present in eukaryotic cells.
Both mitochondria (the energy producer of the cell) and chloroplast (photosynthetic machinery) have their own circular DNA . (The DNA molecules present in the nucleus of eukaryotic cells are in the form of strings and are not circular. ) We know that circular DNA is more primitive as seen in all bacteria, linear DNA definitely evolved later.
What are the products of cellular respiration? Next to each material identify whether it is organic or inorganic.
Answer:
Organic molecules have more chemical potential energy than inorganic molecules
Explanation:
Chemical molecules can either be organic or inorganic depending on whether they contain certain elements. Organic molecules are molecules that contain in their structure a carbon-hydrogen bond (C-H) e.g C2H4, C6H12O6 etc. while inorganic compounds do not contain the carbon and hydrogen elements bonded together e.g CO2, H2S
Considering the substances/compounds involved in photosynthesis and respiration, glucose (C6H12O6) is the only organic compound while every other compound is inorganic. However, organic compounds store more potential energy called chemical energy in its C-C or C-H bonds than inorganic molecules do.
Answer:
Oxygen and Glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP, waste products include carbon dioxide and water.
