Christopher Columbus used the presence of suspended seaweed in the ocean to
determine how far away he was from the coast of the Africa. Seaweed, or kelp, is
placed under the Protista kingătom. What type of protist did Columbus see?
a)protozoa
b) slime mold
c) water mold
d) brown algae
Brown algae is the type of protist Columbus saw. Therefore, option (D) is correct.
What are brown algae?Seaweed is a type of brown algae, which is a type of protist that belongs to the kingdom Protista. Brown algae are large, multicellular algae that grow in the ocean and are often found in shallow, warm waters. They have a complex structure and are made up of many cells that are organized into tissues and organs. Brown algae are photosynthetic, meaning they use sunlight to produce energy and nutrients, and they are an important source of food and habitat for many marine organisms.
Other types of protists include protozoa, which are single-celled, heterotrophic organisms that can move using cilia, flagella, or pseudopodia; slime molds, which are fungi-like organisms that can move and are often found in moist environments; and water molds, which are fungi-like organisms that can grow in water and can cause disease in plants and animals.

If researchers use only the number of coral found in dive 1, calculate the predicted population of brain coral in a reef that covers 120m squared. i forgot how to do this :))
Answer:
40
Explanation:
Each quadrant measured = 2m X 2m
Length = (2+2+2) m = 6m
Width = 2m
Total area = area of (quadrant 1 + quadrant 2 + quadrant 3)
Total area = 6 * 2 = 12 m^2
Number of coral found in dive 1 = 4
Population density = 4/12 = 1/3 (0.33)
Now,
=> Population density = (Predicted population)/area
=> 1/3 = PP/120
=> PP = 120/3 = 40
So, the required answer is 40.
The predicted population of brain coral in a reef covering 120m² is ; ≈ 40
First step : Calculate the value of the default population density
Population density = population size (dive 1) / total area
= 4 / 12 = 0.33
Total area ;
∑ Area of each reef quadrant = length * width = 2 * 2 = 4m²
∴ Total area = 4 + 4 + 4 = 12m².
Final step : Determine the value of the predicted population of brain coral
Population density = ( predicted population ) / predicted area
0.33 = ( pp ) / 120m²
∴ Predicted population ( pp ) = 0.33 * 120
= 39.6 ≈ 40 brain corals
Hence we can conclude that the predicted population of brain coral is 40

Is the coloring of the peppered moths an example of competition, differential reproductive success, or inherited variation? Explain why.
Answer:
Peppered moths get their color in lieu to become the fittest among all so that they can survive easily.
Answer/Explanation:
Differential reproductive success.
When the Birch(white) trees were covered in soot(making them black). The black pepper months could blend in to the tree while the white moths stood out.
When the Birch(white) trees were clean and white. The white pepper moths could blend in to the tree while the black moths stood out.
This is an example of differential reproductive success. Who ever could blend in with the tree had the better genes because it made them difficult to be spotted. The other type of moth would be not so lucky, easily spotted an eaten. The better gene lead is "successful," because that moth could live longer because of its characteristics..

In camellia plants, flower color is controlled by a single gene with codominant alleles. A camellia plants with red flowers (RR) is crossed with a camellia plant with white flowers (WW). What are the expected phenotypes of the offspring of this cross?
A.
All will have red flowers.
B.
Half will have red flowers and half will have white flowers.
C.
All will have both red and white flowers.
D.
All will have pink flowers.
Answer:
The answer is; c
It is important to distinguish between codominance and incomplete dominance.
In incomplete dominance, the two alleles blend with each other in phenotype giving offspring with intermediate phenotypes, hence offspring would produce pink flowers, in this case.
In codominance, both alleles are simultaneously expressed in phenotype in the offspring. Therefore flowers, in this case, would exhibit both red and white colors.

In eukaryotes the electron transport chain is composed of a series of electron carriers located in the blank of mitochondrion
Answer:
Facts that is right
Explanation:
In eukaryotes, the electron transport chain is composed of a series of electron carriers located in the inner membrane of the mitochondrion
The electron transport chain is composed of four large, multiprotein complexes. These protein complexes are formed of a series of electron carriers.
These complexes are embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them.These transfer electrons from electron donors to electron acceptors via redox reactions and joins this electron transfer with the transfer of protons across a membrane.Thus, in eukaryotes, the electron transport chain is composed of a series of electron carriers located in the inner membrane of the mitochondrion
