Answer: the factors that increase cardiac output include:
--> Nervous stimulation and
--> Hypertrophy of the heart.
Explanation:
Cardiac output can be defined as the quantity of blood pumped into the aorta each minute by the heart. This is also the quantity of blood that flows through the circulation. There are factors that can cause increased cardiac output or that can lead to a hypereffective heart. They are:
--> NERVOUS STIMULATION: The combination of sympathetic stimulation and parasympathetic inhibition does two things to increase the pumping effectiveness or cardiac output of the heart. These include:
• it greatly increase the heart rate from the normal level of 72 beats/mum up to 180 to 200 beats /mom.
• it increases the strength of heart contraction, which is called increased contractility to twice it's normal strength.
--> HYPERTROPHY OF THE HEART: A long term increased workload, but not so much excess load that it damages the heart, causes the heart muscle to increase in mass and contractile strength in the same way that heavy exercise causes skeletal muscles to hypertrophy. This effect of increased muscle mass of the heart, allows the heart to pump much greater than usual amounts of cardiac output.

What is one of the biomolecules for which nitrogen is needed (hint: they help build muscles)?
One of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.
What is the significance of the nitrogen in the protein?Proteins play many important roles in the body, including building and repairing tissues, and nitrogen is a critical component of proteins, as it is incorporated into the molecule as a part of the amino acids. Without nitrogen, proteins would not be able to form and perform their many important functions so a diet that is rich in protein is important for athletes and bodybuilders to build and repair muscle tissue.
As a result, of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.

explain the effects of the production of large amounts of antidiuretic hormone in the human body
Answer:
Antiuretic hormone is a hormone that performs functions related to the reabsorption of water molecules through of the kidneys and with the decrease in the amount of urine accumulated in the body. An excess of antiuretic hormone conditions a retention of water and the elimination of sodium in the urine
Explanation:
Antidiuretic hormone (ADH) participates in regulating the water balance in the body, controlling the amount of water reabsorbed by the kidneys after they have filtered waste from the blood. Excess ADH leads to increased water reabsorption in the collecting duct, with increased urinary osmolarity. If there is too much ADH, water is retained, blood volume increases and affect can lead to nausea, headaches, disorientation, lethargy and hyponatraemia (decreased sodium concentration in the blood).

What is reflex arc?A reflex arc is a neural pathway that mediates a reflex action. It is a rapid and automatic response to a specific stimulus that does not require conscious thought or decision-making from the brain. When a sensory receptor in the body, such as the skin or muscles, is stimulated, a nerve impulse is transmitted to the spinal cord, where it is processed by an interneuron.
The interneuron then sends a signal through a motor neuron to the effector, such as a muscle, causing a rapid and involuntary response, such as pulling your hand away from a hot stove. This entire process occurs without conscious control from the brain, allowing for quick and protective responses to potentially harmful stimuli.

Clematis C. Delphinium D. Ranunculus
Question:
Use the following dichotomous key to identify an irregular blue flower with five petals and a fruit that is a ripened flower ovary or follicle.
Dichotomous Key of Ranunculaceae
#1.
a. Fruit is a group of alkenes.............................. go to step 2
b. Fruit is a group of follicles..............................go to step 4
#2.
a. Petals are not present.....................................go to step 3
b. Petals are present............................................Ranunculus
#3.
a. The flower has 4 sepals.................................. Clematis
b. The flower has 5 sepals................................... Anemone
#4.
a. The flowers are regular..................................... Aquilegia
b. The flowers are irregular................................... Delphinium
The flower is a: A. Anemone B. Clematis C. Delphinium D. Ranunculus
Answer:
The species belongs to Delphinium genera.
Explanation:
A dichotomous key is relatively simple to interpret. All you need to do is to:
- carefully observe your organism,
- know some technical terms or have a biological dictionary, and
- follow the descriptions.
The dichotomous key is going to lead you to the answer.
In the example, we have a plant species with irregular blue flowers and five petals. The fruits are a ripened flower ovary or follicles.
Irregular flower: Term that refers to asymmetrical flowers that only have one plane. Follicle: Term that refers to dry dehiscent fruits originated from a flower with only one carpel. When mature, they open by the ventral suture.So, let us begin, step by step. For each number, we are going to have two options (a and b). By knowing our organism, we need to decide which one is correct and follow indications.
#1.
a. Fruit is a group of alkenes.............................. go to step 2.
b. Fruit is a group of follicles..............................go to step 4.
We know that our fruit is a follicle. Option a is not correct (it is not a group of alkenes). Option b is the correct one. Knowing this, we must go to step four. ***Note: In the hypothetical case that the fruits were a group of alkenes, and option a was correct, we should go to step two, as indicated***.
#4.
a. The flowers are regular..................................... Aquilegia
b. The flowers are irregular................................... Delphinium
We know that our flower is an irregular one. So the correct option is b. This option leads us to Delphinium genera. Our species belongs to this taxonomic group. ***Note: In the hypothetical case that the fruit was actually a regular flower, and option a was correct, our species would belong to Aquilegia genera***

These receptors are effective becauseGroup of answer choicesthey detect only human immune molecules.they result in rapid evolution of the host immune system.they recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.PAMPs evolve more quickly than other pathogen molecules.
They recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.
What are Pattern recognition receptor molecules?Pattern recognition receptor molecules detect pathogen-associated molecular patterns (PAMPs), which are structurally conserved components of pathogens such as bacteria, viruses, and fungi. These molecules are essential for the survival and function of the pathogen, and are not found in the host's cells.
By recognizing PAMPs, the immune system can quickly identify and respond to a wide range of potential pathogens, without needing to recognize every individual pathogen separately. Therefore, the receptors are effective because they recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.
