Blood tests can be used to check a person’s blood glucose and hormone levels. The tabular column given below shows the result of two blood tests carried out on three people to check their blood glucose levels. Person 1 is healthy.
a.Compare the glucose levels of person 1 with the glucose levels of person 2 after fasting for12 hours.
b.Compare the glucose levels of person 3 with the glucose levels of person 1, 2 hours after drinking 75g glucose.
c.Person 3 cannot produce the hormone that controls blood glucose levels. State the hormone that person 3 cannot produce.
Pic is the table to refer.
pls answer it is urgent
Answer:
See the answer below
Explanation:
a) From the table, the glucose level of person 1 (5.4) was less than the glucose level of person 2 (5.6) after 12 hours of fasting. The glucose level of person 1 falls within the normal fasting blood sugar range (3.9 to 5.6 mmol/L) while that of person 2 was borderline higher than normal.
b) Also from the table, the glucose level of person 3 (12.1) was greater than that of person 1 (6.4) when the glucose levels were measured 2 hours after drinking 75 g glucose. Normal after-meal sugar level ranges between 6 and 10.9 mmol/L. Hence, person 3 appears to be diabetic while person 1 seems normal.
c) The hormone that person 3 cannot produce is insulin.
Insulin helps lower blood sugar levels when necessary by signalling the liver to convert the excess sugar to glycogen which is then stored in the body. When the blood sugar falls below the normal range, another enzyme, glucagon, signals the liver to convert the glycogen back to sugar to compensate for the decrease.
What are the methods of waste disposal ? Write in briefly.
Answer:
Methods of waste disposal are :-
Biogas plant: - Biodegradable material is used to produce biogas and manure.
Sewage treatment plant: The drain water is treated at plants before adding it to river.
Land filings: - The waste are buried in low-lying areas and compacted with bulldozers.
Composting: - Organic waste are filled in compost pit to make compost for plants.
Recycle: - This means that you collect plastic, paper, glass and metal items and recycle these materials to make required things instead of synthesizing or extracting fresh plastic, paper, glass or metal. In order to recycle, we first need to segregate our wastes so that the material that can be recycled is not dumped along with other wastes.
Reuse: - This is actually even better than recycling because the process of recycling uses some energy. In the ‘reuse’ strategy, you simply use things again and again. Instead of throwing away used envelopes, you can reverse it and use it again. The plastic bottles in which you buy various food-items like jam or pickle can be used for storing things in the kitchen.
Refuse: -This means to say No to things people offer you that you do not need. Refuse to buy products that can harm you and the environment, say No to single-use plastic carry bags.
Repurpose - This means when a product can no more be used for the original purpose, think carefully and use it for some other useful purpose. For example, cracked crockery, or cups with broken handles can be used to grow small plants and as feeding vessels for birds.

Describe the thickness of the uterus lining during
menstruation process.
Answer:
As the cycle progresses and moves towards ovulation, the endometrium grows thicker, up to about 11 mm. About 14 days into a person's cycle, hormones trigger the release of an egg. During this secretory phase, endometrial thickness is at its greatest and can reach 16 mm.
Explanation:
Answer:
During this timeframe, the uterus is in the proliferative phase. Estrogen induces growth of the functional layer of the endometrial lining, which enables it to grow from about 1-3 mm post cycle to 6-8 mm approximately. Days 12-16 of the menstrual cycle At this point, the endometrial layer is about 6-8 mm thick.
Explanation:
The DNA of a prokaryote is arranged in a single coiled chromosome located in a region called the ____________ . Some prokaryotes carry genes on extrachromosomal pieces of circular DNA called ____________ .
Answer:
1. Nucleoid
2. Plasmid
Explanation:
Prokaryotes are groups of organisms characterized by the lack of a membrane-bound nucleus in their cell. Due to this, the genetic material (DNA) of prokaryotes are found naked i.e. not housed. The DNA of a prokaryote is arranged in a single coiled chromosome located in a region of the cell called NUCLEOID.
However, some prokaryotes e.g. bacteria carry genes on extrachromosomal pieces of circular DNA called PLASMID. Plasmids carry certain genes like antibiotic resistance genes.
Hantavirus is a relatively rare emerging infectious disease that is spread by contact with the contaminated feces and urine of rodents, such as deer mice. It does not spread between people and causes flu-like symptoms. How would scientists most likely recommend that the disease be controlled?
Answer:
They would instead focus on controlling and diminishing the rodent population.
Explanation:
They would instead focus on controlling and diminishing the rodent population. The best solutions are always those that target the cause of the problem. Therefore, since the cause of the virus are rodents and that is how the virus spreads, then targetting the rodent population would be the best choice. The scientists would have to figure out a way of keeping track and controlling where the rodent population moves, as well as figuring out how to control their reproduction and diminish their population size. All of this while also trying to predict the possible effects that the population size can have on the environment.

"All honey flora are plants, but all plants are not honey flora". Justify.
Answer:
Beekeeping is affected by adverse climatic conditions and availability of floral resources. This study aimed to survey and characterize the flora in São João do Piauí, a semi-arid region in Piauí, Brazil, and to identify species providing resources to bees. Flowering plants were observed for 18 months, and records were taken of flowering date, growth habit, visitation and resources collected by bees. Melissopalinological analysis of honey produced in the area was performed. A total of 67 flowering plant species were recorded, of which 49 were considered as bee plants, with a predominance of herbs and shrubs. The low rainfall reduces the number of flowering species, which makes important the conservation and multiplication of species which bloom in dry season, such as Ipomoea glabra, Myracrodruon urundeuva, Sida cordifolia and Ziziphus joazeiro, as well as species that contribute to honey production such as Mimosa tenuiflora, Mesosphaerum suaveolens and Croton sonderianus.

Amy, a high-strung teenager, was suddenly startled by a loud bang that sounded like a gunshot. Her heartbeat accelerated rapidly. When she realized that the noise was only a car backfiring, she felt greatly relieved but her heart kept beating heavily for several minutes more. What hormone was released into her bloodstream that is causing this response
Answer:
Catecholamines, endothelins, glucocorticosteroids and thyroid hormones.
Explanation:
Catecholamines, endothelins, glucocorticosteroids and thyroid hormones are the type of hormones that is released into the bloodstream that causes increase of heart rate. Stress and anxiety is responsible for the raising of your heart rate. It may also increases when you're very happy or upset. People who have severe obesity can have a slightly faster pulse as compared to normal people.
In the nephron, the highest concentration of salt is found surrounding the
Select one:
a. loop of Henle.
b. Bowman's capsule.
c. distal convoluted tubule.
d. proximal convoluted tubule.
Answer:
The correct answer is - distal convoluted tubule.
Explanation:
Proximal convoluted has the maximum amount of reabsorption and the least amount of salt reabsorption. There will be the maximum amount of salt inside the proximal convoluted tubule as it absorbs most of the salt concentration. Whereas distal proximal tubules have more salt concentration in the surrounding area as they are not able to absorb salt in comparison to the other parts of the nephron.
The correct answer is - distal convoluted tubule.

construct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells
Structure and Function. All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins, which carry out most of the work of cells.
What is the name of the strategy that combines two plant proteins (grains and beans) to get all the essential amino acids
Answer:
Protein combining
Explanation:
The strategy involving the combination of two plant proteins to get all the essential amino acids is referred to as protein combining.
The practice of protein combining is common among vegans due to the general belief that a single plant-based protein does not contain all the necessary amino acids for the body. Thus, one would need to combine 2 plant-based proteins in order to get all the essential amino acids for adequate health.
When two populations of animals which arose from a common ancestor become geographically separated, the populations become increasingly different from one another as each adapts independently to a suite of unique ecological conditions. These populations are said to be __________. Conversely, when two populations of animals, especially those arising from unrelated ancestors, become increasingly similar as they adapt to common (shared) ecological conditions, they are said to be __________
Answer:
divergent; convergent
Explanation:
The first populations of animals are said to have evolutionally diverged while the second populations are said to have evolutionally converged.
In divergent evolution, closely related animal populations accumulate differences (due to differences in their environments) so much so that they can become different species.
In convergent evolution, different animal populations evolve similar traits (due to similarities in their environment).
Hence, the correct words to fill the gaps would be divergent and convergent respectively.
