Answer:
Receptors provide information to nervous system about missing cells.
Explanation:
Your body know when cells are missing due to nervous system. The network of nervous system spreads throughout human body which provide information about what is going on in the body. If the cells are missing due to injury, the nervous system gives instruction to the body to produce more cells and transported that cells to the region where these cell are required. So receptors are responsible to provide information to nervous system about missing cells.
The body knows cells are missing as a result of the receptors sending
to the central nervous system.
The human body consists of cells which have neurons. These neurons are
responsible for the passage of messages and information to other parts of
the body.
When a cell is missing from the body, signals are passed to the central
nervous system which consists of the brain and spinal cord and they then
relay impulses which helps to fix the issue so as to ensure optimal
functioning of the body.

Biologists designed an experiment to test the effects of compost on the development of root crops
Answer:
The crop has good yield because Compost has a good effect on root crops.
Explanation:
Compost has a great effect on the development of root crops such as onion, potato, garlic and ginger etc. Compost provide nutrients to these crops as well as soften the soil due to which they grow rapidly. It also improved ventilation, soil structure and soil texture which is very necessary for the crop. Due to ventilation, oxygen gas is available to the roots which increases growth and yield of these crops. Compost also retain water and nutrients so they are available to the roots. So those plots where compost is applied observed increase in yield as compared to other plots.
What are the phagocytes cell in the skin
Answer: The mononuclear phagocyte system (MPS), which includes macrophages and dendritic cells, has also been implicated in the regulation of skin salt homeostasis and blood pressure [35]
Explanation:
Answer:
The phagocytes cell in the skin are the monocytes, macrophages, neutrophils, tissue dendritic cells and mast cells. One litre of human blood contains about six billion phagocytes.
When pathogens are detected, the immune system produces millions of white blood cells, which fight the infection. Blood vessels near the wound expand, and white blood cells move from the vessels to enter the infected tissues. Many of these white blood cells are phagocytes which engulf and destroy bacteria.
Myristoyl-CoA is a saturated fatty acid with 14 carbons attached to coenzyme A. How many molecules of ATP would be generated from the complete oxidation of a single molecule of myristoyl-CoA
Answer:
Total ATP molecules produced = 94 molecules of ATP
Explanation:
Myristoyl-CoA, is a saturated fatty acid with 14 carbons which has been activated for oxidation by attachment to coenzyme A. When it has undergone complete oxidation, it will yield 7 acetyl-CoA molecules and 6 FADH₂ and 6 NADH molecules each.
Each of the 7 acetyl-CoA molecules obtained from its initial oxidation enters into the citric acid cycle and is completely oxidized to yield further ATP and FADH₂ and NADH molecules.
The overall yield of ATP from the various enzymatic steps is shown below:
Acyl-CoA dehydrodenase = 6 FADH₂
β-Hydroxyacyl-CoA dehydrogenase = 6 NADH
Isocitrate dehydrogenase = 7 NADH
α-Ketoglutarate dehydrogenase = 7 NADH
Succinyl-CoA synthase = 7 ATP (from substrate-level phosphorylation)
Succinate dehydrogenase = 7 FADH₂
Malate dehydrogenase = 7 NADH
Note: 1 FADH2 molecule yields 1.5 ATP; 1 NADH molecule yields 2.5 ATP molecules. Therefore,
Total ATP from FADH₂ molecules = 13 * 1.5 = 19.5
Total NADH molecules = 27 * 2.5 = 67.5
Total ATP molecules produced = 19.5 + 67.5 + 7 = 94
Total ATP molecules produced = 94 molecules of ATP
who invented biology
Answer:
The term biology in its modern sense appears to have been introduced independently by Thomas Beddoes (in 1799), Karl Friedrich Burdach (in 1800), Gottfried Reinhold Treviranus (Biologie oder Philosophie der lebenden Natur, 1802) and Jean-Baptiste Lamarck (Hydrogéologie, 1802).
Explanation:
When was biology invented?
Antiquity
The science of biology was invented by Aristotle (384–322 BC). Before Aristotle, many Greek philosophers had speculated about the origins of the Earth and of Life, but their theorizing was unsupported by empirical investigation.
what is the key to the recognition of a trait whose expression is determined by the effects of two or more genes
Answer:
Explanation:
Polygenic inheritance occurs when many loci of a gene contributes to it genetic make up.
No particular allele can be selected for contributing to a particular traits all the allele are equally expressed.
Over expressitivity example is pleiotrophy effect have more than 5 fingers or toes

A purebred tall pea plant is cross-pollinated with a tall, heterozygous pea plant. Use a Punnett square to determine the probability the offspring inherita
recessive short allele. (I point)
75%
25%
0%
50%
Answer:
The correct answer is - 25%
Explanation:
A cross between true tall pea plant and heterozygous tall pea plant is the cross of tall allele whic is TT and heterozygous which is Tt, so the gametes will be formed would be - T and T by true tall plant and T, and t allele by heterozygous plant.
The Punnett square of this cross is attached with the answer, where 2 heterozygous offspring and two tall offspring produced. In which there is only two recessive short allele formed in this generation out of 8 alleles.
So the probability of short allele would be:
= (2/8) *100
= (1/4) *100
= 25%

Food microbiologists are scientists who have a background in both microbiology and food science. They focus on how microbes grow, cause disease, and how they can be identified from food. Their work is of importance to the food industry as it relates to the production, preservation, and spoilage of food; and it is of importance to public health and regulatory agencies due to the many diseases that are related to food intake and consumption. Food microbiologists can have varying backgrounds, including training in veterinary medicine. This scenario is about a food microbiologist who works as a food safety inspector who pays a visit to a cheese manufacturing plant and makes some interesting discoveries!
Part A-Understanding the Role of Microbes in Fermentation The Midwest is known for its contribution to the dairy industry Fermented dairy products include milk, yogurt, and cheese. The fermentation process relies on lactic acid bacteria and pasteurization. Fermentation can vary based on what food is being produced, the type of bacteria used to produce lactic acid, and the time and temperature of pasteurization. It is important to the manufacturer to produce a product that won't spoil before it is packaged and sold and that won't result in disease for those who ingest and enjoy it. Julie, a food inspector for a local Michigan health department is going to a nearby cheese plant for a biannual inspection. When she gets there, she will take a tour of the plant and allow the operators to describe what makes their cheese so special. She will use what she understands about fermentation to inquire about their production practices Please sort the following statements as being true or false regarding fermentation and its role in food production. Please recall the role that microorganisms can play in the production of foods.
1. Fermentation allows for sugars to be broken down
2. Starter cutures are for the growth of pathogens or the food such as bread, vegetables, and n food Some grains, fruits, and
3. Fermentation can be used only to Bacteria ane the only have their own microbes that used in the Correct Statements
Answer:
Statements 1 is True.
Fermentation allows for sugars to be broken down
Statements 2 and 3 are false.
Starter cutures are for the growth of pathogens or the food such as bread, vegetables, and n food Some grains, fruits, and
3. Fermentation can be used only to Bacteria ane the only have their own microbes that used in the Correct Statements
Explanation:
In microbiology, fermentation is the process where sugars are broken down by the activities of bacteria to produce alcohol and carbondioxide...therefore statement one is true.
Starter culture are microorganisms use in diary production for producing yoghurt and cheese. They perform fermentation in diary production.
The role of the ___________ branch of the autonomic nervous system mediates control of organ processes when the body is essentially ______.
Answer: parasympathetic; at rest
Explanation: The parasympathetic nervous system branch of the autonomic nervous system is largely responsible for the relaxation of the body especially at rest where it undoes the activities of the sympathetic branch by decreasing respiration, heart rate and then increasing the body's digestion rate. As such, this branch is also responsible for digestion response in a relaxed, resting, or feeding states. The role therefore of the parasympathetic branch of the autonomic nervous system mediates control of organ processes when the body is essentially at rest.

What is a biological approach to determining when a mother and her conceptus become separate individuals?
Answer:
Electroencephalography.
Explanation:
Electroencephalography is used to measure brain activity in terms of electrical activity. It is done by attaching electrodes on the scalp, or sometimes by placing electrodes directly in the brain. Using electroencephalography can help determine when the fetus starts having its own brain activities, which means that it is now a separate entity distinguishable from its mother. Using electroencephalography to see brain waves can give us a deeper insight into the age old complicated issue of when a mother and her conceptus become separate individuals.
Describe the transport properties of the loop of Henle and explain the interactions between the ascending and descending limbs
Answer:
The loop of henle is a part of the renal functional unit.
This handle has an ascending part and a descending part.
In the descending loop, the urine that is formed inside enters a hypotonia, since a large amount of water is absorbed and the concentrations of solutes in the urine decrease, thus generating a hypoosmolar solution, that is, with less molarity.
In the ascending loop of henle, the opposite arises, ionic channels appear that increase the concentration of solutes, this is how the urine that runs through the interior of the ascending loop of henle becomes hyperosmolar.
Hyperosmolarity is the increase in concentrations of solutes, and the increase in molarity of the solution, which in this case would be urine.
Explanation:
A very important fact is that urea is absorbed in the ascending henle loop.

a. Sabita is blind from a diet devoid of fortified milk, animal products, or dark yellow and orange fruits and vegetables.
b. Sabita has an enlarged thyroid gland due to a dependence on unfortified salt.
Nutrient:
1. Iron
2. Vitamin A
3. Vitamin D
4. Iodine
Answer:
a. Sabita is blind from a diet devoid of fortified milk, animal products, or dark yellow and orange fruits and vegetables. - Vitamin A
Sabita is suffering from Vitamin A deficiency. A lack of Vitamin A usually shows itself with night blindness but can cause complete blindness if not acted upon quickly.
Vitamin A deficiency is quite common in developing or poorer nations such as the area Sabita is located and usually attacks children of women in their reproductive stage. Sources of vitamin A include; fortified milk, animal products and fruits and vegetables.
b. Sabita has an enlarged thyroid gland due to a dependence on unfortified salt. - Iodine
Iodine deficiency leads to an abnormal enlargement of the thyroid gland leading to a condition known as Goiter which presents itself as a big bulge in a person's neck. Iodine is usually placed in fortified salt along with iron to reduce iodine deficiency so Sabita's dependence on unfortified salt is robbing her of a great source of Iodine.
The condition in which the body is deprived of minerals, vitamins and other macro and micronutrients are called malnutrition.
The correct matches and their explanation are as follows:
a. The correct answer is:
Option 2. Vitamin A
Sabita is blind from meals deficient in fortified milk, animal products, fruits and vegetables due to Vitamin A deficiency.Night blindness is a common symptom of a Vitamin A deficiency.It is most common in developing regions due to the lack of proper meals. The best source of vitamin A is milk, fruits and animal products like eggs.b. The correct answer is:
Option 4. Iodine
Sabita has a swollen thyroid gland due to habituation on unfortified salt deficient in Iodine.Iodine deficient diet causes thyroid gland enlargement a disease called Goiter. This type of disease also affects glucose metabolism and weight.To learn more about malnutrition and diet follow the link:

¿Qué características crees que deben tener los métodos anticonceptivos para ser eficaces en el control de la natalidad?
Answer:
Los métodos anticonceptivos para ser eficaces en el control de la natalidad deben ser seguros para las personas que los utilizan, es decir, no tener efectos adversos, o al menos, la menor cantidad posible. Ser reversibles, es decir, que no generen infertilidad de por vida. Deben ser además fáciles de usar, cómodos y fáciles de conseguir, esto es, económicos. Además deben ser eficientes en su objetivo de evitar la concepción, que es para lo que fueron creados.
Explanation:
La tasa de eficacia de un método anticonceptivo se mide por la cantidad de embarazos que se producen cada 100. Esta parece ser la característica más importante, y si bien es una de las más importantes, hay que tener en cuenta todos los otros factores mencionados, es decir que la gente pueda acceder a ellos, sean cómodos, seguros y a un precio coherente.
"If an organism were to die in an environment that had no saprotrophs or detritivores, what would you expect to see if you observed the area 2 weeks later?"
Answer: The options are not given, here are the options.
A. There will be no difference as compared to an area that has saprotrophs and detritivores. •
B. There would be nothing left, it will have completely decomposed. •
C. The body would remain, and be just as it was when it died except for weathering. •
D. The body would be decomposing at about half the normal speed.
The correct option is C.
The body would remain, and be just as it was when it died except for weathering.
Explanation:
"If an organism were to die in an environment that had no saprotrophs or detritivores, The body would remain, and be just as it was when it died except for weathering because detrivores and feed on organic matter and excrete the nutrients, without detrivores and saprotroph the the organic matter in the dead organisms will still remain the same.
Detrivores are organisms that feed on dead organic matter and releasing nutrients to the ecosystem through it's wastes.
Saprotroph are decomposers that survive on or in dead organic matter secreting enzymes and releasing nutrients to the ecosystem. Examples is fungi.
Without detrivore and and saprotroph the dead organisms will remain the same except from weathering be side weathering is carried out through the activities of air, water or some agents.
