According to the National
Institute of Health, ventricular tachycardia is a fast, regular beating of the ventricles that may last for only a few seconds or for much longer. A few beats of ventricular tachycardia often doesn't cause
problems. However, episodes that last for more than a few seconds can be dangerous. Ventricular tachycardia can turn into other, more serious arrhythmias, such as ventricular fibrillation.
Based on the passage above, how will prolonged ventricular tachycardia affect blood pressure?
O It will increase blood pressure because the ventricles are contracting with more force.
O It will increase blood pressure because the ventricles are filling with more blood between beats.
O It will decrease blood pressure because there is a longer rest period beats of the ventricles.
O It will decrease blood pressure because the ventricles are filling with less blood between beats.
Answer:
It will decrease blood pressure because the ventricles are filling with less blood between beats.
Explanation:
In ventricular tachycardia, the heart beats faster than normal, usually 100 or ... The chaotic heartbeats prevent the heart chambers from properly filling with blood. As a result, your heart may not be able to pump enough blood to your body
Answer:
It will decrease blood pressure because there is a longer rest period beats of the ventricles.

Explain how the body prevents particles in inspired air from reaching the gas
exchange surfaces.
Your respiratory system prevents harmful substances from entering the lungs by using: .Mucus produced in the trachea and bronchial tubes to keep air passages moist and aid in intercepting dust, bacteria and other substances; The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean
Mucus produced in the trachea and bronchial tubes to keep air passages moist and aid in intercepting dust, bacteria and other substances; The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean.
What is inspired air?Due to exchanges that occur in the alveoli, the amount of gases in the air that is breathed in and out varies. We only take in about 4 to 5 percent of the oxygen found in atmospheric air, and we exhale air with about 16% oxygen.
Normal air contains about 0.04% carbon dioxide, and as it diffuses from the blood into the alveoli, we exhale air with about 4% carbon dioxide. Exhaled air is hotter than that which we breathe in and includes more water vapor than that which we breathe in.
In contrast to ordinary smell, which occurs during the inhalation phase, the olfactory contribution to flavor occurs during the exhalation process. As a result, we can conclude that expired air differs from inspired air in terms of oxygen content, bacterial density, and water vapor content.
Therefore, Mucus produced in the trachea and bronchial tubes to keep air passages moist and aid in intercepting dust, bacteria and other substances; The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean.

where does reabsorbtion of glucose take place?
glomerulus
bowman's capsule
2nd coiled tubule
1st coiled tubule
Answer:
proximal tubule
Explanation:
Glucose reabsorption takes place in the proximal tubule of the nephron, a tube leading out of Bowman's capsule. The cells that line the proximal tubule recapture valuable molecules, including glucose.Under normal circumstances, up to 180 g/day of glucose is filtered by the renal glomerulus and virtually all of it is subsequently reabsorbed in the proximal convoluted tubule.

what is the function of cell nucleus?
Answer:
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.

Explain the structure of the nucleus in a living cell
Answer:
The nucleus contains nearly all of the cell's DNA, surrounded by a network of fibrous intermediate filaments and enveloped in a double membrane called the "nuclear envelope". The nuclear envelope separates the fluid inside the nucleus, called the nucleoplasm, from the rest of the cell.
hope that helps<3
Answer:
Look at the explanation
Explanation:
Nucleus is situated in the cytoplasm of the cell.
Usually, it is round but many different shaped nuclei can be seen in some cells.
It is surrounded by two porous membranes called nuclear membranes which remain continuous with the Endoplasmic Reticulum.
Within the nuclear membrane is present a liquid substance called nucleoplasm.
Nucleoplasm contains two types of chromatin material: Heterochromatin and Euchromatin.
Chromatin fibres are thin thread-like structures composed of DNA and proteins.
These fibres condense to form short thick chromosomes during cell division and become visible.
DNA molecules transfer hereditary information from one generation to the next.

Why do some ecosystems remain stable for centuries while others undergo succession
As long as the ecosystem inputs remain the same, the ecosystem will remain stable. Only when there is a fire, drought, or other disturbance in the ecosystem, will the ecosystem change. A new set of plants will arise to most efficiently use the resources that are available under the new conditions. However, over time, if the disturbance is temporary, the ecosystem will eventually revert to the stable ecosystem that was there before the disturbance.
What is a stable ecosystem?Stability (of an ecosystem) refers to the capability of a natural system to apply self—regulating mechanisms so as to return to a steady state after an outside disturbance.
What is succession?Ecological succession is the process of change in the species structure of an ecological community over time.
Causes of succession:Topographical: Extreme conditions cause abiotic topographical factors, which are mainly involved with secondary succession. Landslides and mudslides are examples of this type of factor.Soil: The soil, an abiotic factor, of an environment affects ecological primary succession greatly. Different species of plants require different soil conditions.Climate: Climate, an abiotic factor highly involved in both primary and secondary succession, plays a significant role in determining the direction of succession in an environment. Ecosystem remains stable: It’s all about balance, left to its own devises nature constantly rebalances.populations increase and decrease all the time, usually due to food sources either being plentiful or scarce, when plentiful the animals that feed on them thrive and breed.when scarce they starve and decline in number, this decline in numbers allows time for the food source to regrow or reproduce (if the food source is another animal species), The ecosystem is unaffected in the long run and remains in balance.Thus, it can be concluded that As long as the ecosystem inputs remain the same, the ecosystem will remain stable.

This fossil turtle and this living hawk both have a structure in their neck called the atlas bone. What best explains why both species have an atlas bone?
a) The turtle and hawk are different species, so they must not share an ancestor population. They inherited their atlas bone structure from separate ancestor populations.
b) The turtle and hawk both share the same ancestor population that had an atlas bone. They inherited this structure from the ancestor population.
c) It is impossible to say. Fossils are very old; therefore, we cannot make observations of the turtle’s ancestors, and we cannot explain its body structures.

The rocky material left behind by a retreating glacier forms what is called a moraine. When primary succession occurs on a moraine, which life-forms will help create the soil by breaking down bare rock?
A Insects
B Lichens
C Grasses
D Deciduous trees
Answer:
The correct answer is - B. Lichens.
Explanation:
Lichens are one of the pioneer species that can grow on bare rock such as moraine and help make soil for further ecological succession and making ground for other species.
Breaking the bare rocks to convert into the soil is part of the primary succession. Lichens are colonized over these rocks and they contain acid which leads to the breakdown of the moraine and other rocks.
Haploid gametes produced in females that are used in fertilization are called polar bodies.
