Mitosis is the division of the cell and begins with a stage called prophase. As the nuclear envelope finishes dissolving, the cells enter prometaphase, where microtubules from the spindle attach to the duplicated X-shaped chromosomes.
When all chromosomes are fully attached to the spindle, they align at the midplate between poles. This marks the middle of mitosis, which is metaphase. As sister chromatids separate, cells enter anaphase and they finish separating, and a nucleus reforms around each set of new chromosomes in telophase.

1. Which of the following events is not a source of genetic variation in eukaryotic organisms?
J. Mutation
K. Independent assortment
L. Mitosis
M. Fertilisation
Answer:
Mitosis
Explanation:
Mitosis is not a source of genetic mutation because it take place mostly in the somatic cells. This is because it does not lead to the production of gametes . In mitosis, the parent cells divide into two daughter cells and each daughter cells are genetically identical to the parent cell because they carry the same number of chromosomes as the parent cell. There is no genetic variation in this.

The temperature equivalent to 77°F is
°C.
Use the formula to convert the temperature.
Answer:
25 degree celcius
Explanation:
formula
(given degree Fahrenheit - 32)×5÷9
(77 - 32)× 5÷9
= 25°C
Here I will show you how to convert 77 F to C so you know how hot or cold 77 degrees Fahrenheit is in Celsius. The F to C formula is (F − 32) × 5/9 = C. When we enter 77 for F in the formula, we get (77 − 32) × 5/9 = C.
so therefore the answer is 25 degrees celsius
As a genetic counselor, you advise couples about the possibility of genetic disease in their offspring. This morning you met with an engaged couple, both of whom are phenotypically normal. The man, however, has a brother who died of Duchenne-type muscular dystrophy, an X-linked condition that results in death before the age of 20. The allele responsible for this disease is recessive. His fiancee, whose family has no history of the disease, is worried that the couple's sons or daughters might be afflicted.
Requied:
a. How would you advise this couple?
b. The sister of this man is planning to marry his fiancée's brother. How would you advise this second couple?
Answer:
a. This couple should not worry.
b. This couple should worry.
Explanation:
a. The man should not be worried. This is because he is normal (phenotypically).
b. They should be worried because the sister of the man can be a carrier of the recessive allele. If she was a carrier, then half of their male children can be affected.

1) Bacteria respond to changes in their environments, such as nutrient availability, by regulating their metabolic pathways. Describe two mechanisms that bacteria use in order to adapt to environmental changes. Include in your answer which mechanism is a short-term or long-term adaptation. (Pg. 364, paragraph 3, sentence 2; paragraph 4, sentence 1)
Answer:
Examples:
- Short-term adaptation: feedback inhibition
- Long-term adaptation: regulation of gene expression
Explanation:
Feedback inhibition is a mechanism where the product of a chemical reaction is utilized to modulate its own subsequent synthesis. In bacteria, feedback inhibition allows regulating different metabolic pathways in response to environmental conditions by modulating enzyme activity through enzyme reaction products. Moreover, bacteria may also respond to environmental inputs by long-term changes in gene expression. For example, bacteria contain transcription factors activated during stress, which are able to activate the transcription of particular genes into messenger RNAs (mRNAs) that would subsequently be used to generate particular enzymes by the process of translation. These transcription factors may bind to specific DNA motifs in order to promote transcriptional activity, thereby regulating the production of the corresponding enzyme.
How might a wildfire influence mass wasting? By drying out (removing the water) from the regolith on a slope, wildfires decrease the likelihood of a mass wasting event. A wildfire can dry out the regolith on a slope, making it less cohesive and more likely to travel downward. Wildfires burn only at the bottom of a slope, which oversteepens the slope and induces mass wasting. The ash from the wildfires lands on the slope, adding enough mass to instigate mass wasting. Because plants on a slope bind the regolith with their roots and shield the soil surface from raindrops, a wildfire that destroys these plants would render the soil looser and more susceptible to the erosional forces of rain.
Answer:
Because plants on a slope bind the regolith with their roots and shield the soil surface from raindrops, a wildfire that destroys these plants would render the soil looser and more susceptible to the erosional forces of rain.
Explanation:
The plants present in a region, protect the soil from being eroded by the impact of rain or wind. This is because the roots of the plants leave the soil more aggregated, block the impact of the wind and allow water to infiltrate. This protection is increased on slopes, where the chances of erosion are greater. However, when a fire occurs and these plants are killed, the roots no longer provide protection to the soil, leaving it drier and looser. This causes the wind to break this soil apart, facilitating erosion. In addition, rainwater has difficulties in infiltrating the soil and ends up draining, taking parts of the soil with it and causing erosion.

Which of these is a result of crossing over?
a.) Decrease in the number of chromosomes
b.) Exchange of proteins
c.) Exchange of genetic material
d.) Increase in the number of chromosomes
The result of crossing over is the exchange of genetic material that is present in Option C because this only happens in meiosis during the prophase and results in different gametes.
What is the importance of crossing over?"Crossing over" is a process that occurs during meiosis of cell division in sexually reproducing organisms that produces gametes such as sperm and eggs. During crossing over, the genetic material in the parent cells' chromosomes is exchanged, resulting in new combinations of genes in the gametes, and the importance of crossing over is that it creates genetic diversity within a population.
Hence, the result of crossing over is the exchange of genetic material that is present in Option C because this only happens in meiosis during the prophase and results in different gametes.

Answer: Primary succession: Glaciers, bare rock, lichen
Secondary succession: Wildfires, volcanoes, hurricanes, deforestation
Explanation:
Succession in ecology can be defined as gradual changes that occur in the biotic community in an ecosystem with respect to the changes that occur in the abiotic components of the environment. Primary succession initiate in an land which is not previously occupied by any living species. These includes the changes that occur at the primitive level on the land. That is the formation of glacier from the ice, bare rock will undergo withering and disintegration to form the soil, lichen are the biological composite organisms formed by the mutual association of algae and fungi. These lichens act upon the rocks to cause its withering by releasing the chemicals causing disintegration of the rocks.
Secondary succession occurs at those regions which have been colonized by the living species and get disturbed due to human oriented or natural disasters. Wildfires can be set up naturally, through volcanic eruption, or can be human induced can clear up the forests but some remains of seeds and deep rooted roots can help in growth of new plants which will again initiate the succession, again volcanoes, and hurricanes, are also natural hazards which can affect the population of species in an ecosystem. Deforestation is a human oriented practice in which vegetation cover or forests are clear cut. This will also cause loss of biodiversity.
