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.

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.

Nonsense mutation. A nonsense mutation is also a change in one DNA base pair. Instead of substituting one amino acid for another, however, the altered DNA sequence prematurely signals the cell to stop building a protein. This type of mutation results in a shortened protein that may function improperly or not at all.Sep 21, 2020

about rocks in geology class and tells her mom that the formation is made of gneiss, a type of
metamorphic rock. How did this metamorphic rock form?
Answers
Answer:it was heated and under pressure
Explanation:
Metamorphic rocks are formed from existing rocks, under high temperature and high pressure. This process is called metamorphism.
What is a metamorphic rock?Metamorphic rocks are those rocks that are formed from different kinds of rock like igneous, sedimentary, or gneiss rock under high pressure and intense temperature. They are rigid in nature.
In the formation of metamorphic rocks, firstly existing rock is broken down into small particles by physical, chemical, or biological agents. The process of breaking down rock is called weathering. Then erosion and transportation of these particles take place by the wind, water, or any biological agent.
The next step involves compaction after sedimentation. Thus, metamorphic rocks are formed from existing rocks.

Answers
Answer:
Postharvest physiology plays a fundamental role in extending the shelf-life and quality of plant products. An example of postharvest physiology methodologies is by reducing the temperature to improve shelf-life before consumption
Explanation:
Postharvest physiology refers to the methodologies used for extending shelf-life and quality, thus being a critical issue in food systems. Postharvest approaches include chemical treatments, temperature reduction, cleaning and disinfection methods, etc. Crop varieties are genetically selected in order to maintain nutritional qualities of stored seeds for a long time after harvest. These seeds are also controlled during storage by using postharvest handling practices (e.g., chemical and enzyme inhibitors that extend shelf life).

Five different types of heterotrophs are carnivores, herbivores, omnivores, scavengers, and detritivores.
Carnivores eat the meat of other animals. Example: Bear
Herbivores eat vegetation. Example: Deer
Omnivores eat a combination of both meat and vegetation. Example: Humans
Scavengers eat things left behind by carnivores and herbivores. Example: Raccoon
Detritivores eat small bits of organic matter, such as soil. Example: Worms
