the sun shines on a flagpole, causing a shadow to be cast on the ground.the sun shines on a flagpole, causing a shadow to be cast on the ground. the distance from the base of the pole to the tip of the shadow is 49 feet. at that time of day, the sun's rays make an angle of 38° with the ground. How tall is the flagpole?​

Answers

Answer:

38.3 feets

Explanation:

Given :

From the diagram attached below ; we could apply trigonometry to obtain the height of the flagpole:

Tan θ = opposite / Adjacent

θ = 38° ; opposite = height of flagpole, h

Adjacent = 49 feets

Tan 38 = h / 49

0.7812856 = h / 49

Height of flagpole = 0.7812856 * 49

Height of flagpole = 38.282

Height of flagpole = 38.3 feets

What is the end product of amino acids converted to urea and excreted

Answers

Answer:

When in excess, the amino acids are processed and stored as glucose or ketones. The nitrogen waste that is liberated in this process is converted to urea in the urea acid cycle and eliminated in the urine. In times of starvation, amino acids can be used as an energy source and processed through the Krebs cycle.

Explanation:

Amino acid catabolism results in waste ammonia. All animals need a way to excrete this product. Most aquatic organisms, or ammonotelic organisms, excrete ammonia without converting it.

Why are lymph nodes considered secondary lymphoid tissue?
Lymph nodes produce white blood cells, but they do not use white blood cells to fight infection.
Lymph nodes use white blood cells to fight infection, but they do not produce white blood cells.
Lymph nodes are the second line of defense against infection.
Lymph nodes are produced by the primary lymphoid tissues.

Answers

Explanation:

they filter out pathogens they mantain the population of mature lymphocytes

The secondary lymphoid organs are the lymph nodes and spleen, which keep the number of mature lymphocytes in check and filter out infections, hence option B is correct.

What is secondary lymphoid tissue?

The thymus, where T-lymphocytes develop, and red bone marrow, which produces blood and immune cells, are the two main lymphoid organs.

Lymphocytes are also stimulated in secondary lymphoid tissues. Peyer's patches, tonsils, spleen, lymph nodes, and mucosa-associated lymphoid tissue are among them (MALT).

Numerous lymphocytes, a kind of white blood cell, are found in lymph nodes. They produce substances that stimulate other immune system components and aid in the battle against the illness. This is the reason why when you have an infection, your lymph nodes expand.

Therefore, the lymphocytes in your lymph nodes grow if you have an infection, hence option B is correct.

Sophia is hoarse and malnourished with nosebleeds.
Sophia complains of itching, nausea, and a racing heart.
Sophia has severe dental problems, anxiety, and a sleep disorder.

Answers

the first one

impaired memory and learning because it is long term effect so the docotor usually choose it

Explanation:

THC is the short-form term for delta-9-tetrahydrocannabinol, which is the psychoactive chemical in marijuana. Blood carries THC to the brain where it acts on cannabinoid receptors (the complexes that interact with the cannabinoid neurotransmitter). Cannabinoids naturally occur in the body.

The general effect of cannabinoids on cannabinoid receptor sites is to slow down communications between the cells in the body and the brain. The presence of THC has a similar effect, which is why marijuana is often associated with a relaxing and calming effect. THC also triggers the brain’s reward system, which results in the pleasurable effects associated with marijuana.

The symptoms observed by the doctor in Sofia as an indication of the use of marijuana are impaired memory and learning.

Marijuana is the name by which the cannabis plant is known. This plant is characterized by the psychotropic effects as a result of "consuming it smoked". However, over the years it has been scientifically proven that it can be the main component of medical treatments.

When used for leisure, its consumption can have side effects such as:

Behavioral symptoms: Engaging in risky behavior / criminal activities, felayed reaction time, presence of behaviors aimed at obtaining drugs, decreased motivation, decreased academic performance, inability to fulfill job responsibilities among others.Physical symptoms: Loss of motor skills, reduction in muscle strength, acceleration of the heart rate, increased appetite, hypertension, redness of the eyes, among others.Cognitive symptoms: Memory loss, distorted perception, difficulty thinking or solving problems, problems understanding time or wasting time, lack of concentration, learning impairments, making poor decisions, tendency to forget things during a conversation, among others.Psychosocial symptoms: Anxiety, panic or fear reactions, depressed mood, increased irritability, agitation, increased anxiety, among others.

According to the above, the symptoms that the doctor in Sophia perceives that allow him to confirm his suspicion that she has been using marijuana for a long period are her impaired memory and learning.
