I need help with this (#20)
tester [92]

Answer:

a Anaphase I

b Metaphase I

c Telophase I

d Anaphase II

e Prophase I

f Telophase II

Explanation:

Prophase I begins after the DNA has been duplicated, as shown in picture e. The chromosomes are condensed, and also visible, which is apparent in picture e.

The next stage is called Metaphase I, in which the pairs of homologous chromosomes align at The the centre of the cell and the spindle fibres attach, as shown in picture b.

The pairs of chromosomes are pulled apart to opposite poles of the cell by the spindle fibres., as shown in picture a. This stage is called Anaphase I.

Then, a process called Telophase I occurs, when the cell divides into two daughter cells. One of these cells is shown in picture c.

Picture d shows the stage Anaphase II, where the spindle has attached and the chromatids are pulled to the opposite poles of the cell.

The final picture left is picture f, which shows the daughter cell at the end of meiosis II, where the nuclear envelope is reforming, as in telophase II.

If an organism does not have its own means of locomotion and it produces new cells out of inorganic materials through the photos
Travka [436]

The organism is a plant.

Plants are photosynthetic and autotrophic organisms, characterized by plant cells containing chlorophyll. The plants do not have locomation devices and are therefore immobile.

Photyosynthesis starts from inorganic ingredients (CO2 and H2O) to give an organic molecule (glucose) and oxygen at the end.

Which is true about a daughter cell produced by mitosis? A. It is a haploid cell. B. It is connected to the parent cell. C. It c
ANTONII [103]

Answer:

D. It can function independently

Explanation:

A. Not a haploid, the daughter cell is going to be a diploid cell, because it is a body cell, not a sex cell; they are suppose to have the same amount of chromosomes as the parent cells.

B. It will go through cytokineses ( last step of the mitosis) the cells will not be connected to parent cell and is independent (D)

C. Inside the chromosomes, no matter it is a haploid or diploid cell, it will contain DNA.  

D. After going through the cell cycle, the new daughter cell produced will be a new individual and do not connect to other cells.

Which of the following statements is correct regarding engineering maize plants with a herbicide-resistance gene using Agrobacte
Mariulka [41]

Answer:

b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.

Explanation:

Ti-plasmid has the ability to introduce part of its DNA (t-DNA) into the genome of host plants. This is very important for the relationship of genetic manipulation in maize plants, with the aim of inducing a gene that promotes herbicide resistance. In addition, T-DNA has many genes that code for the production of plant growth phytohormones, which is extremely important for the cloning process to work. In this case, we can assume that the correct answer for yours is the letter B.
