The subclavian trunks of the lymphatic system filter lymph from the upper limbs and upper external part of the thorax.
The lymphatic system is an open system and is a part of the immune system. It consists of lymphatic vessels, lymph nodes, lymphoid tissues, and organs.
The lymphatic system is responsible for the circulation of a clear fluid which is known as the lymph.
The lymph contains lymphocytes which help in fighting against infections and diseases. The lymphocytes are produced in the primary lymphoid organs which are the thymus and bone marrow.
The subclavian trunks are formed after the unification of the efferent vessels of the subclavicular groups.

david decided to modulate his blood glucose level by increasing fiberintake. what will be the least effective food
The least effective food would be corn flakes to modulate blood glucose level as it has the least amount of fiber.
Fiber :
Fiber is a type of carbohydrate which the body can’t digest. Although fiber cannot be converted into glucose, the sugar that results from the breakdown of most carbs, fiber travels through the body undigested. In order to control appetite and blood sugar levels, fiber helps the body consume glucose in a more controlled manner.
Constipation, diverticular disease, heart disease, diabetes, and other illnesses all seem to be at a reduced risk when fiber is consumed. In the gut microbiota, fiber has a positive role that may have anti-inflammatory effects that reduce the chronic inflammation linked to various illnesses.

A potentially fatal condition with sudden onset, characterized by uremia, that can be caused by the kidneys not receiving enough blood to filter is called Renal artery stenosis or Acute kidney failure.
The narrowing of one or more arteries that supply blood to your kidneys is known as renal artery stenosis (renal arteries).Your kidneys can't get enough oxygen-rich blood because of artery narrowing. To assist in filtering waste materials and eliminating extra fluids, your kidneys require a sufficient blood flow. Your kidneys' decreased blood flow could harm renal tissue and raise your body's blood pressure.Clogging of the renal arteries. Your renal artery walls are susceptible to plaque buildup from fats, cholesterol, and other chemicals (atherosclerosis). Larger deposits have the potential to harden, decrease blood flow, result in kidney scarring, and ultimately restrict the artery.

Which of the resources above do you believe would be the most difficult to reproduce once it runs out? Why do you think this is?
Waste management would be the most difficult to reproduce once it runs out. Thus, option "C" is the answer.
What is waste management?Waste management~ includes the activities and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process.
For example, Incineration is the process of burning of solid wastes. It is one of the processes of solid waste management. In this process, combustion of organic and inorganic wastes takes place that leads to the formation of ash, heat and flue gases. Ash is composed of inorganic constituents.
The heat generated during this process can be used to generate electricity. The process is carried out by Incinerators. Incinerators does not completely replace landfilling but it reduces the volume of disposal of wastes.

Use the internet to find out more about kidney machines and kidney transplants . how is the donor's kidney tested to see whether it is suitable? why is rejection of the new kidney a problem and how is it dealt with?
Answer:
The kidney is tested to see whether it is suitable for donation by checking for diseases and conditions that could make it unsuitable for transplantation.
The rejection of the new kidney is a problem because it is not able to remove waste from the blood properly. The nephrons inside the kidney are not able to filter the blood properly and the waste accumulates in the body. The body then has to find a way to remove the waste and this can be done through dialysis or a transplant.

Meninges :
The meninges are the three membranes which envelop the brain and spinal cord and separate them from the walls of their bony cases (skull and vertebral column). Meninges are classified as either spinal meninges, which encase the spinal cord, or cranial meninges, which surround the brain.
The major function of the meninges is to protect the brain and spinal cord from mechanical stress, to support the blood vessels and to create a continuous canal through which cerebrospinal fluid (CSF) flows.

Transfer of children between mothers is known as cross-fostering. This method is used to distinguish between environmental and genetic impacts on behavior. Transferring some freshly born or hatched young of species A from their mother nest to the nests of species B is the primary process of cross-fostering.A behavior can be proven to have a genetic foundation if cross-fostered offspring have a behavioral attribute that is distinct from that of their foster parents and similar to that of their biological parents. Similarly, environmental variables are proven to be dominating if the offspring exhibits qualities that are different from those of their biological parents and comparable to those of their foster parents.There is frequently a combination of the two, demonstrating both genes.

Hydras and jellyfish both live in a freshwater lake that is slowly being acidified by the runoff from a chemical plant built upstream. Which population is predicted to be better able to cope with the changing environment
Answer:
Hydras
Explanation:
Algae support hydras because they provide hydras oxygen. Hydras have regenerative ability; they do not appear to die of old age, or to age at all. But sometimes, disease, predators and water contamination kill off hydras before they can achieve "immortality".
Jellyfish need to stay in the water to survive. They get their oxygen from their really thin skin. In some cases, it has been found that jellyfish have an immune system that presents bacterial-specific responses.
In the absence of an adaptive immune system, Hydra polyps employ an elaborate innate immune system to detect and interact with microbes using their two cell layers as efficient defense barriers, making them survive longer or have better defense against the chemicals.
Also take into consideration, what chemicals/acids are being put into the lake and the "age" of the hydra/jellyfish.

During fertilization, the sperm and egg combine in one of the fallopian tubes to form a zygote. The zygote then descends the fallopian tube into a morula. Upon reaching the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the inner wall of the uterus. This is a process called implantation.
