Answer:
Please find the answers to numbers 10 and 11 of the attached image below.
Explanation:
10. This question lists the stages of mitosis namely: prophase, metaphase, anaphase, and telophase. The major events that take place in each of these stages are as follows:
A) PROPHASE:
- the supercoiled chromosomes known as chromatin begins to condense making it visible.
- spindle begins to emerge from the centrosome organelle.
- Nuclear envelope begins to break down in order to expose the chromosomes in the nucleus.
B) METAPHASE:
- The chromosome are aligned at the cell plate i.e. the equator/middle of the cell.
C) ANAPHASE:
- The sister chromatids of each chromosome i.e. replicated chromosomes are pulled apart at the centromere by spindle microtubules to the opposite poles of the cell.
D) TELOPHASE:
- Chromosomes at opposite poles begin to decondense into chromatin.
- The nuclear envelope reforms around the chromosomes
11) Cytokinesis is the process that occurs after mitosis (nuclear division). It is the process whereby the cell whose chromosomes are now separated into opposite poles divide into two. In other words, a cell divides into two in the cytokinesis stage.

Answers
Answer:
Please find the explanation of the differences between chromosomal DNA and plasmid DNA below
Explanation:
As stated in this question, a bacteria cell contains both chromosomal or genomic DNA and an extra chromosomal DNA called PLASMID. They are both circular in shape but are different from one another in the following ways:
- Chromosomal DNA is larger in appearance than the plasmid DNA, hence, they differ in terms of size.
- Chromosomal DNA encodes all the information in the genome of the bacterial cell necessary for their growth and development while plasmid DNA encodes few additional beneficial characteristics such as antibiotic resistance, virulence etc.
- Chromosomal DNA is wrapped around histone proteins to form the chromosome structure but plasmid DNA is naked and not wrapped around histone proteins.

Plants can't walk to different places and take their seeds somewhere else they have developed other methods to move their seeds. The most common methods are wind, water, animals, explosions and fire. Dandelion seeds float in the wind.
Explanation:
There are five different types of seed dispersal and they are gravity, wind, ballistic, water, and animals.
g It has been proposed that integrin proteins undergo conformational changes when they bind to small molecules diffusing into the extracellular matrix. Because integrins are transmembrane proteins, a change in their conformation can be transmitted across the membrane to the portion of the protein that interacts with intracellular structures. What biological role does this allow integrins to play in a cell's function within a multicellular organism
Answers
Answer:
Cell-cell communication
Explanation:
Integrins are heterodimeric transmembrane receptors that facilitate the adhesion to the cell-extracellular matrix by attaching the cytoskeleton to this matrix. Moreover, integrins also help the cells bind with other cells. Integrins are responsible for the communication between cells and thus control tissue structure. These receptors are responsible for the attachment of fibroblasts to collagen, as well as the attachment of fibroblasts to fibronectin. It is also important to highlight that the binding of integrins with their corresponding ligands activates signaling pathways that control diverse cellular processes including, among others, cell growth, cell development, cell migration, phagocytosis, etc.

You now find new cells which contains 200 mM CaCl2 and 15 mM glucose. The cell membrane is permeable to Ca ions, impermeable to Cl- ions, impermeable to Na ions and impermeable to glucose. You transfer these cells into a solution which has 140 mM (NaCl) and 150 mM glucose. What happens to the cells after the solution and cell have come to equilibrium
Answers
Answer:
The correct answer would be - ions will move from solution 1 to solution 2 so the cell will shrink.
Explanation:
The concentration of CaCl2- = 200mM
CaCl2 dissociates in the three different ions in a solution and each has the same osmolarity
The concentration of glucose = 15 mM
So, the osmolarity of solution 1 would be:
3 × 200 + 15= 615 mM
Similarly, the osmolarity of the second solution would be
The concentration of NaCl = 140 mM
The concentration of glucose = 150 mM
NaCl dissociates in the two different ions in a solution and each has the same osmolarity
140×2+ 150= 430 mM
The solution has more concentration of ions than solution two so the movement of the calcium ion of the CaCl2- would be possible only and therefore, the cell in solution 1 will shrink.

Which enzyme activate vitamin K in the liver and blocked by which drug?
Answers
Answer:
menadione
Explanation:
Vitamin K is a fat soluble vitamin that exists in two natural forms: phytonadione (K1: fye toe" na dye' one) which is derived from plant sources and menadione (K2: men" a dye’ one) which is derived from bacterial sources. Vitamin K is a cofactor in the photosynthetic electron-transport system in green plants, which are the major dietary source of vitamin K for humans. High levels of vitamin K1 are found in leafy green vegetables while vitamin K2 is found in meat, milk and butter. In humans, vitamin K is an essential cofactor in the gamma-carboxylation of glutamate residues of several clotting factors and anticoagulant proteins. Hope this helps!
