What is the best evidence telling you whether this cell is diploid or haploid? what is the best evidence telling you whether this cell is diploid or haploid? the cell is diploid because it contains two sets of chromosomes. the cell is haploid because the chromosomes are not found in pairs. the cell is diploid because each chromosome consists of two chromatids?

Answers

The answer would be: The cell is diploid because it contains two sets of chromosomes

The only way to diagnosis haploid cells would be by exclusion. To do that you need to examine all the chromosome and make sure that they are no coupled chromosomes.
But you can diagnosis diploid right away if you can find two sets of any chromosomes.

The renal tubules secrete h+ into the tubular fluid, where most of it binds to bicarbonate, ammonia, and phosphate buffers.

Answers

The renal control of pH buffering involves neutralizing more acid or base more than other systems in the body because they can also expel them from the body. The renal tubule secretes H+ into tubular fluid, where most of it binds to bicarbonate, ammonia, and phosphate buffers in renal tubules. Therefore the bound and free H+ excreted is excreted in urine. Other body systems only reduce the concentration by binding it to chemical buffers.

An adult client, diagnosed with narcolepsy, admits being embarrassed to receive this diagnosis and is adamant that no one find out about it. the nurse should respond to the client by explaining what aspect of the etiology?

Answers

The correct answer is "this is the result of neurological factors over which you have no direct control".
Narcolepsy is a neurological condition which blocks a person's ability to control its sleep-wake cycle. Common symptoms could be bad sleep quality, hallucinations while sleeping, sudden loss of muscle strength and excessive sense of sleepiness during the day. Being a neurological condition, patients have no control over their symptoms. The causes of the disorder are unknown, only a very small percentage of the cases (10%) is considered to be familial. Specific psychological conditions, such as trauma, are suggested to play a role. 

A skeletal muscle deprived of adequate atp supplies will _____.

Answers

The correct answer is that the skeletal muscle will enter a state wherein actin and myosin cannot separate. In the presence of adequate ATP, ATP will act to detach the myosin head to actin then ATP will be hydrolyzed to ADP then the myosin head will attach to actin. In the absence of adequate ATP, there will be no ATP to detach the myosin head to actin therefore the actin and myosin cannot separate and muscles will be contracted and stiff. This happens in ATP depletion and muscle stiffness in dead persons called rigor mortis.

Explanation:

Small intestine breaks down food enzymatically into small enough pieces for the nutrients to be absorbed. Which statement best describes this process?

Option D Small intestine changes the chemical composition of food.

As said in the question, the small intestines breaks down food with the aid of chemical digestion i.e. using enzyme/chemicals to break down food from larger state to smaller ones enabling the nutrients to be absorbed. This enzymatic/chemical addition changes the chemical composition of the substances. For instance, protein is broken down by the enzyme trypsin into the smaller forms of peptides and amino acids allowing them to get absorbed into the surrounding environment.

Answers

DNA does not move out of the nucleus

Answer:

Option). it never moves out of the nucleus.

Explanation:

DNA and RNA are nucleic acids, made up of sugar, nitrogen bases, and phosphate groups. Both DNA and RNA are involved in the process of protein synthesis as information present in DNA is first transferred to RNA (transcription) and from RNA to protein (translation).

Generally DNA acts as genetic material in all living organisms, but in some viruses, RNA acts as genetic material. Both DNA and RNA have four types of nitrogenous bases.

DNA never comes out of the nucleus, but during protein synthesis RNA comes out from the nucleus as in eukaryotes, RNA is synthesized in nucleus, while translation takes place in cytosol.

Thus, the correct answer is fourth option.

"classifications of lipoproteins include: very low density lipoproteins, low density lipoproteins, high density lipoproteins and __________."

Answers

The four types of  Lipoproteins are:

Very Low Density Lipoprotein: Very low density lipoprotein consists of protein, cholestrol and fats. It is synthesized at liver. It has 5 apoporotein asosciated with it and in conversion to intermediate density lipoprotein and low density lipoprotein these apoproteins are removed except one apoprotein called B100.

Low Density Lipoproteinfats. It chiefly consists of cholestrol. It transport all the fat molecules around the body to extracellular fluid. LDL posses risk of cardiovascualr diseases if it invade the endothellium  and oxidized.

High Density Lipoprotein: HDL is the dense lipoprotein with highest protein to fat ratio.HDL takes awat fat from cells to liver thereby lowering blood cholestrol level. Hence also knows as good cholestrol. HDL increases with exercise, weight loss and higher estrogen level.

Chylomicrons: Chylomucrons are largest and least dense lipoprotein. It has got highest triglyceride content. It transport fats and cholestrol from intestine to liver, muscles and fat cells.

 

The right answer is chylomicrons.

A chylomicron is a variety of lipoproteins (protein-associated lipids) present in the blood consisting almost entirely of exogenous triglycerides.

In other words, it is large, light and bulky particles, of a greasy nature, taking a certain shape in the blood (which has a milky appearance when they circulate there), and carrying the triglycerides coming from the diet after a meal. high in fat.

Any stimulus that, when removed after a response, strengthens the response is called a(n) positive reinforcer. negative reinforcer. unconditioned stimulus. conditioned stimulus.

Answers

A negative reinforcer is any stimulus that, when removed after a response, strengthens the response.
Final answer:

Negative reinforcement refers to the strengthening of a behavior by the removal of an undesirable stimulus after the behavior occurs. In contrast to positive reinforcement, which strengthens a behavior by adding a positive stimulus, negative reinforcement works by subtracting a negative one.

Explanation:

Any stimulus that, when removed after a response, strengthens the response is called a negative reinforcer. It is a term used in operant conditioning, a form of learning where the strength of a behavior is modified by its consequences, such as reward or punishment. The concept behind negative reinforcement is that by removing an undesirable stimulus after a behavior, that behavior will increase. For instance, if a student studies hard and as a result, the teacher cancels a scheduled test (an undesirable stimulus), the student's studying behavior might increase.

Its counterpart, positive reinforcement, refers to the addition of a pleasurable stimulus to increase the behavior. In contrast, a negative reinforcer involves removing an aversive stimulus to enforce the desired behavior. Both of these techniques aim to increase the likeliness of a behavior.

Assisted suicide requires some action on the part of the client, and this is not possible for a one- month old infant.  Both the nurse and the parents have an ethical duty to the child. Withholding the opioid analgesic from a dying child is not appropriate, because, of fear it may hasten death, at any age, and this is not considered a contradiction for administering of analgesia.

You are on the scene in the bad part of town for an unresponsive 18-year-old type 1 diabetic patient. his mother states that he is very noncompliant with his diabetes management and goes unresponsive often due to low blood sugar. after performing the primary assessment, you believe that this is the most likely cause of his unresponsiveness. however, after taking a capillary glucose reading you are surprised to see that the patient's sugar level is normal. how will you now determine the field impression?

Answers

The answer would be: Continue patient care by getting a complete SAMPLE history and perform a complete secondary assessment.

If the reading of glucose test is normal, then you can exclude hypoglycemia from the possible diagnosis. Because the patient is accompanied by his mother, you can ask a brief history to exclude other possible diagnosis and complete secondary assessment before further help comes. The information would be beneficial to the healthcare personnel that will comes for help.

Final answer:

In the case of an unresponsive type 1 diabetic patient with a normal blood sugar reading, one must consider differential diagnoses other than hypoglycemia. Tests like the insulin and glucagon tolerance tests help deduce the underlying cause of unresponsiveness. Monitoring blood glucose and maintaining strict dietary adherence are crucial in managing diabetes.

Explanation:

When an 18-year-old type 1 diabetic patient exhibits unresponsiveness and a capillary glucose reading reveals a normal sugar level, a differential diagnosis must be conducted to arrive at a correct field impression. This would include considering possibilities beyond hypoglycemia, such as hyperglycemia, ketoacidosis, or other medical conditions. Given the patient's history of noncompliance, it's crucial to consider if hormone resistance might be a factor, as is common in type 2 diabetes; however, type 1 diabetics are not usually hormone-resistant. It may also be necessary to conduct further tests, such as an insulin tolerance test or glucagon tolerance test, to understand the patient's specific diabetes complications, like defective insulin receptors or excessive insulin antagonists indicated by varying responses to hormone injections.

Water is transported to the leaves where it is combined with _________ to form a sugar.

Answers

Water is transported from the roots, where the main portion of water is absorbed, and up the plant through the xylem; the xylem is an interconnected system of tubes where the water circulates through the plant. Water then flows through the cortex of the plant, through the endodermis, or innermost layer of cells, and finally into the cells' vascular bundles. Transpiration, which is the evaporation of water through the stomata, is responsible for the movement of the water from the xylem into the mesophyll cells and finally into the leaves.
