ment is always true of work?
A) It is difficult.
B) It involves levers.
C) It involves a transfer of energy.
D) It is done with a machine.

Answers

Answer 1

Answer: C. It involves a transfer of energy.

Answer 2

Using the scientific definition, the statement that is always true of work is it involves a transfer of energy. The correct option is C.

What scientific theories?

Scientific theories are the theories that are given by scientific facts and information. These theories are based on observation of natural things and places.

There is the transfer of energy in the natural world. Every organism and plant is connected with each other in the form of a transfer of energy. This is called a food chain.

In the food chain, the organism is divided into different levels. These levels are based on their food. They are autotrophs, heterotrophs, and decomposers. Autotrophs have the largest amount of energy.

Thus, the correct option is C) It involves a transfer of energy.

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 :))

Answers

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

Answers

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

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.

Answers

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.

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.
