After a meal, blood glucose levels rise and stimulate the secretion of which hormone?
a. glucagon
b. glycogen
c. pancreatisone
d. insulin
Answers
After a meal, blood glucose levels rise and stimulate the secretion of insulin.
After a meal, when blood glucose levels rise, the pancreas releases insulin into the bloodstream. Insulin is a hormone that plays a crucial role in regulating blood sugar levels. Its primary function is to facilitate the uptake of glucose from the bloodstream into cells, where it can be utilized for energy production or stored for future use.
Insulin acts on various tissues, including muscle, liver, and adipose (fat) tissue. In muscle and adipose tissue, insulin promotes the uptake of glucose by increasing the number of glucose transporters on the cell surface. This allows glucose to enter the cells more efficiently. In the liver, insulin inhibits the production and release of glucose, reducing the amount of glucose that is released into the bloodstream.
By promoting the uptake and utilization of glucose, insulin helps to lower blood glucose levels, preventing them from becoming excessively high. It also promotes the storage of excess glucose as glycogen in the liver and muscles for later use.
Overall, insulin acts as a key regulator of glucose metabolism and helps maintain blood glucose homeostasis.

Discussion 1. What percentage of asci observed resulted from the fusion of cells from different strains? 2. What percentage of those asci resulting from the fusion of different strains demonstrates crossovers?
Answers
During the study of genetics and inheritance, it is important to observe the sexual cycle of fungi to determine the genetic variations within the offspring. In the 1920s, T. H. Morgan and his colleagues used fungal genetics to test the hypothesis of the existence of recombination. For instance, they observed the sexual cycle of the common bread mold, Neurospora crassa, to investigate how crossing-over occurs between homologous chromosomes during meiosis.
As a result of their investigation, Morgan and his colleagues discovered that, during meiosis, four haploid ascospores are produced within a specialized sac called an ascus. These ascospores are produced when two nuclei from two different hyphae (cells) combine and fuse together.
This fusion creates a cell with two haploid nuclei, which subsequently undergoes meiosis to create four haploid ascospores. Hence, an ascus will contain four haploid ascospores produced by a single diploid cell resulting from the fusion of two haploid cells.
The percentage of asci observed that resulted from the fusion of cells from different strains is 100%. This is because the fusion of haploid cells from different strains is essential for the production of a diploid cell that will then undergo meiosis to form four haploid ascospores.

what was the problem with reusing contaminated water from other parts of the mill to extinguish the coke fires? From the book ‘When smoke ran like water’
Answers
Answer:
1. The problem with that was that the already poisonous water was made worse after using it to quench the flames from coke production.
2. It contaminated the soil, making it difficult for plants to grow.
Explanation:
As the author described the last stages of coke production, she explained that water was needed to quench the very hot flames from coke production. A 'bright fellow' suggested using dirty water from other parts of the mill to quench the flames from the coke production. The problems with this were;
1. The already contaminated water was made worse after it was used to quench the flames from coke.
2. Mrs. LaMendola noted that she was unable to grow her tomatoes in the path where the plumes from the oven ran. So the contaminated water negatively affected the soil.
The problem that should be already poisonous water is also made worse when it quenches the flames at the time when the production of the coke should be done.
Also, it contaminated the soil also it is difficult for growing the plants.
The problem of reusing contaminated water:Since the author explained the last coke production stage so here the water required to quench that it should be very hot flames arise from the coke production. Also, the contaminated water should be worse whenever it is used for quenching the flames. Also, the contaminated water does not positively impact the soil.

Explanation:
Hope this helps!
Starch paste and starch milk are different in their constituents as starch paste contains a mixture of cellulose which is added to rice or wheat whereas starch milk is just raw starch with fibers in it.
What are starch paste and starch milk?Starch paste is a water-soluble adhesive which is primarily used to bond the sheets of paper. It is widely used in paper industry. It is made from the starch of the grains, potatoes, or other plants that are easily available. Before hardening of this paste, starch paste is a highly viscous, gel-like mixture with high moisture content. The starch paste based adhesives adhere well to the cellulosic materials hence used widely in industries.
The waste product formed from the mashed potatoes smuggling with water i.e., the dewatered potato pulp is known as the starch milk.

Guppies with spots that are the same size as the rocks on the bottom are harder for bigger fish to see and catch. The diagram above shows a population of guppies that lived in a river. Scientists had previously only seen guppies with medium or large spots in this river; they had never seen any guppies with any other spot sizes. The diagram below shows how the population changed after many generations.
• Karina says the change in the guppy population was caused by a mutation.

The statement 'Karina says the change in the guppy population was caused by a mutation' is correct. Mutations change the frequency of phenotypic traits in a population across generations.
What is evolution?The word 'evolution' refers to descendence with modification which especially happens due to the process of natural selection.
The mutations in the genetic material serve as raw material for natural selection and consequently for evolution.

Are r-selected species short lived?
Answers
R-selected species are indeed short-lived.
Species whose populations are governed by their biotic potential are called r-selected species.
Biotic potential is defined to be the maximum reproductive capacity of a species under optimum environmental conditions. Environmental resistance, which includes any factor that holds back the increase in number of the population, restricts full expression of the biotic potential of a species.
The defining characteristic of r-selected species is the production of numerous small offspring, followed by exponential population growth. R-selected species mature quickly (thus require little or even no parental care), require short gestation periods, and are short-lived. Members of this group, unlike K-selected species, are capable of reproduction at a relatively young age, but many offspring die before they reach reproductive age.

Answers
The half-life of the given radioactive isotope is approximately 1.49 days.
To determine the half-life of the radioactive isotope, we can use the formula:
N(t) = N0 * (1/2)^(t/T)
where N(t) is the activity at time t, N0 is the initial activity, t is the time elapsed, and T is the half-life.
In this case, N0 = 400,000 Bq, N(t) = 170,000 Bq, and t = 2 days. We can now solve for T:
170,000 = 400,000 * (1/2)^(2/T)
Divide by 400,000:
0.425 = (1/2)^(2/T)
Take the natural logarithm of both sides:
ln(0.425) = (2/T) * ln(1/2)
Now, solve for T:
T = 2 * ln(1/2) / ln(0.425)
T ≈ 1.49 days

However, using too much fertiliser can be harmful because it causes eutrophication and the emission of greenhouse gases.

Farmers must add this essential plant nutrient when soils are unable to provide crops with the K levels they require.When urea is added to the soil, it quickly turns into ammonium through a reaction with water and the soil enzyme urease.
