Where is this storage protein found?

please help

Answers

Answer:

Storage proteins serve as biological reserves of metal ions and amino acids, used by organisms. They are found in plant seeds, egg whites, and milk. Ferritin is an example of a storage protein that stores iron. Iron is a component of heme, which is contained in the transport protein, hemoglobin and in cytochromes.

One line with red flowers and the other line with violet flowers. You carry out a monohybrid cross and find that all of the F1 offspring have violet flowers, while 97 of 400 F2 offspring have red flowers.
Explain the inheritance of flower colour in this plant species.

Answers

Answer:

See the answer below

Explanation:

The inheritance of flower color in the plant species follows the simple dominance/recessive inheritance of Mendel. The red flower trait did not show up at all at F1 only for it to show up at F2. It simply means that the red flower trait is recessive while the violet flower color is dominant.

Assuming that the allele for violet flower color is designated as R while that of red flower color is designated as r. The genotype of the violet flower would be true-breeding, RR, while that of red flower color would also be true-breeding rr:

RR x rr

F1 Rr Rr Rr Rr

phenotype ratio = all violet flower color

Rr x Rr

F2 RR Rr Rr rr

phenotype ratio = 3/4 violet flower color and 1/4 red flower color

97 red flower offspring out of 400 is approximately 1/4.

Hence, the inheritance of flower color in the plant obeys a simple dominant/recessive Mendelian law with the violet color trait dominant over the red color trait.

The picture shows a 3-D model of a virus called a bacteriophage. Bacteriophages can infect In what way are the bactenophage and E. coli alike? F. They contain antibodies. che produce by tutosis. H They have idenbekl genomes, The lack membrane-bound organelles. Students, dawanywhere on this slide!

Answers

G is your answer. I took the test.

Bacteriophage and E.coli are alike in the sense that they both lack membrane-bound organelles.

What are bacteriophage?

Viruses that infect bacteria are called bacteriophage. The words bacteriophage mean "bacteria eater". Bacteriophages take over the machinery of host cells to produce copies of themselves and then destroy the host cell in the process.

Bacteriophages are composed of a supercoiled nucleic acid which is surrounded by a protein capsid.

A bacteriophage adheres to the surface the susceptible bacteria and injects its genetic material. This way they occupy the genetic machinery of the host and produce several copies of their own nucleic acid and also the protein capsid to surround it.

The result is the lysis of bacterial cell and release of thousands of bacteriophage viruses which are capable of infecting more bacteria in the same manner.

Bacteriophage are acellular structures lacking any membrane bound cell organelles. E.coli is a kind of prokaryotic bacteria which also lack membrane bound organelles.

Therefore, the correct option is D.

Answers

Answer:

A. Green after being placed in the light because the plant would remove CO2 by photosynthesis; yellow after being placed in the dark because the plant would release CO2 by respiration.

Explanation:

According to this question, Bromothymol blue (BTB) is a chemical that can be used as an indicator of the pH of a solution. The presence or absence of CO2 in a solution decreases or increases the pH of the solution respectively.

- BTB appears green in a neutral pH i.e. little CO2

- BTB turns yellow in a low pH i.e. high CO2

Plants, in the presence of light, will perform photosynthesis and use CO3 as a reactant while in the dark, will perform cellular respiration and release CO2 as a waste product. Hence, in this case where an aquatic plant was placed into a test tube and covered it to keep it air tight.

- When placed under light for 24 hours, the aquatic plant will undergo photosynthesis and remove CO2 from the solution to make the solution appear GREEN due to neutral pH.

- When placed in the dark for 24 hours, the aquatic plant will undergo cellular respiration and release CO2 into the solution making the solution appear YELLOW due to low pH.

Which of the following has the greatest effect
on soil's capacity to retain water?
A Soil color
B Soil particle size
C Soil texture
D Soil fragrance

Answers

The water-holding capacity of a soil is the the amount of water that a given soil can hold for plants to utilize

The soil particle size has the greatest effect on soil's capacity to retain water.

Soil particle size and organic matter (the soil's composition) are main determinants of water-holding capacity of a soil. Smaller particles (silt and clay) have a bigger surface area than larger sand particles, allowing the soil to hold more water.

What is the probability of short beaks in the offspring of the cross show above

Answers

Answer:

8/16 or 1/2

Explanation:

This question is a dihybrid cross involving two genes, one coding for feather color and the other for beak length. The alleles for green feathers (G) and long beak (L) are dominant over the alleles for yellow feathers (g) and short beak (l).

According to this question, a male with genotype GGLl was crossed with a female with genotype Ggll. The following combination of gametes is produced by each parent:

GGLl - GL, Gl, GL, and Gl

Ggll - Gl, Gl, gl and gl

Using these gametes in a punnet square (see attached image), the following offsprings in the following proportions will be produced.

Green feathers, long beak (GGLl, GgLl) = 8/16 or 1/2

Green feathers, short beak (GGll, Ggll) = 8/16 or 1/2

Hence, the probability of short beaks (ll) in the offspring of the cross is 1/2.

how does an organism reproduce by budding

Answers

Budding is a kind of asexual reproduction. It occurs most commonly in some bacteria and yeast. Organisms which reproduces in this fashion are usually very basic organisms that either lack reproductive organs or both female and male reproductive organs are located internally.
Examples of such animals are:
1. flat worms
2. Jelly fish
3. Sea anemones
4. corals.
5. Yeast cells (such as are found in baker's yeast)
The coral reef is a large colony of living organisms identical to each other, which propagate themselves through budding.

what is the difference between cell structure and cell function?

Answers

Answer:

These cells have a membrane-bound nucleus that houses their DNA and contain extensive internal organelles (“little organs”) that perform specific functions. ... Differences occur in size, shape, and presence and number of various organelles and other structures. Each cell's structure correlates with its specific function.

Explanation:

Answer:

A cell can be defined as the smallest unit of life and an example include muscle cells. An aggregation of cells form tissues.

The major difference between a cell structure and cell function is in their functions and physical properties.

Cell structure: This talks about how the cells look like when viewed. A call contains components such as the nucleus, cytoplasm, cell membrane etc and each has their various functions to ensure the organisms/animals are able to perform various life activities.

Cell function: This on the other hand refers to the various functions which a cell is able to perform and this is dependent on the component in question such as the nucleus which controls cell activities and cytoplasm which provides support and helps to house other organelles.
