Answer:
The correct answer is - B) effective pumping of the ventricles ceases because the myocardial cells fail to work as a team, and the brain cannot get adequate oxygen.
Explanation:
When the heart is in an irregular and rapid heart rate due to chaotic electrical signals in the atrial chambers of the heart which leads to a very fast heart rhythm that shows 100 to 175 heart rate. That leads to failure of the myocardial cells that stop the pumping of the ventricles effectively and therefore blood would not reach the brain and the brain would not get an adequate amount of oxygen. This will result in organisms experiencing faint, blackout or stroke-like complications.
What characteristics do you think could be used to classify different kinds of single-celled organisms? Write your ideas here
Answer: flagellum, a plasma membrane and organelles.
Explanation: In that sense, it can be difficult to find traits that they all share. Still, Project Oceanography at the University of San Francisco indicates that single-celled organisms have a number of common characteristics, including the presence of flagellum, a plasma membrane and organelles.
Flagellum, a plasma membrane and organelles classify different kinds of single celled organism and prokaryotic organism.
What are the different features of prokaryotic cell ?Prokaryotic cell are single celled organism, do not have membrane bound organelles and its size varies from 0.2 μm – 2.0 μm.
Here the Cell wall is present but True Nucleus is absent, the cell wall is mainly involve in photosynthesis and provide protection to cell, the ribosomes are Smaller in size having 70s type and spherical in shape.
Circular DNA is present as genetic material in prokaryotes, Mitochondria is absent in prokaryotes, the reproduction usually occur by binary fission and some times it occurs through conjugation.

What information can be gained about the structure and function of plants by ring barking?
Answer:
About its different layers and their functions in the plant body.
Explanation:
By studying the structure and function of the plants by ring barking, we find out that the ring barking is very important for the plant because it provides support as well as protection to the inner part of the stem against environmental conditions such as temperature and intense light etc. These barks are responsible for the storage of water which can be used during drought conditions. This ring barking provides information about different layers of stems such as periderm, cortical and phloem tissue that has a specific function in the plant body.
Chyangras are only farmed in cold regions. Give reasons.
Answer:
hope this helps
Explanation:
Pashmina wool is a natural adaptation of the Chyangra goat that protects the animal from extreme weather conditions around the Himalayas. That is why they are farmed only in cold regions.
Who are Chyangra Goats?Chyangra goat is a type of famous breed of mountain goats which is found in the high altitude areas of the Himalayan region. It produces the world's most expensive and finest quality of luxurious cashmere wool. It is also used for meat. They are more famous for the development of the world famous pashmina wool industry in Nepal and India.
Pashmina wool is a natural adaptation of the Chyangra goat that protects the animal from extreme weather conditions around the Himalayas. The specialty of pashmina is that it can retain enough heat to protect the animal from the severe cold and strong wind of the high mountains all year round.
Thus, Pashmina wool is a natural adaptation of the Chyangra goat that protects the animal from extreme weather conditions around the Himalayas. That is why they are farmed only in cold regions.

You are observing a woodland habitat and take note of a few trophic
relationships. You identify a few species of ferns that are being eaten by beetles.
You are also able to observe a snake in the process of eating a small species of
finch. You analyze your notes later and realize you missed a part of the food
chain. What part are you missing?
A. Tertiary Consumer eating Producer
OB. Secondary consumer eating Tertiary Consumer
C. Producer eating Primary Consumer
D. Secondary Consumer eating Primary Consumer
By analyzing the notes, one can say that in the given scenario, secondary consumer eating primary consumer is missing. The correct option is D.
What are consumers?A consumer in a food chain is a living being that consumes organisms from another population. A heterotroph is a consumer, and an autotroph is a producer.
As in the notes it is mentioned that ferns are eating beetles, and snakes are eating finch. It is lacking secondary consumers eating primary consumers.
Thus, the correct option is D.

When environmental conditions change, selection can cause a change in the distribution of phenotypes of that species. Which of the following trends would provide evidence of disruptive selection in response to environmental change?
A shift in a population's frequency curve from an intermediate phenotype to an extreme phenotype
A shift toward equal distribution of all phenotype frequencies, including intermediate and extreme phenotypes
An increase in the frequency of extreme phenotypes and a decrease in the frequency of intermediate phenotypes
An increase in the frequency of intermediate phenotypes and a decrease in the frequency of extreme phenotypes
Answer:
One of the extreme phenotypes has the highest fitness. The bell curve shifts towards the more fit phenotype.
so I think w ould say the second one
Explanation:
Answer:
An increase in the frequency of extreme phenotypes and a decrease in the frequency of intermediate phenotypes
Explanation:
A disruptive selection is one where the extreme phenotype frequencies are increased and the intermediate phenotype frequencies are decreased.

A student created a table to compare animal adaptations. Based on the table, which
animal has a behavioral adaptation, and how does it give the animal an advantage?
Animal Adaptation
Duck Webbed feet
Squirrel Collects and stores food
The duck, because the behavioral adaptation allows it to catch prey.
The duck, because the behavioral adaptation helps it survive the environment.
The squirrel, because the behavioral adaptation provides food during winter.
The squirrel, because the behavioral adaptation to have more offspring.
Answer:
B
Explanation:
Ducks have the webbed feet so, they could swim in the water so they don't drown. That is animal adaptation to the environment.
Based on the given table, the animal with a behavioral adaptation is the squirrel, which collects and stores food. This adaptation gives the squirrel an advantage by helping it survive during times when food is scarce, such as during the winter months, which is in the third option.
What is behavioral adaptation?The behavioral adaptation of collecting and storing food is an important survival strategy for many animals, including squirrels. During times of abundance, such as the fall months, squirrels will collect and store food, such as nuts and seeds, in order to have a food source during times of scarcity, such as the winter months. This allows the squirrel to survive and avoid starvation during times when food is less readily available.
Hence, Based on the given table, the animal with a behavioral adaptation is the squirrel, which collects and stores food. This adaptation gives the squirrel an advantage by helping it survive during times when food is scarce, such as during the winter months, which is in the third option.

are the most reactive metals.
15. The elements in group_
are the most reactive nonmetals.
16. The elements in group_
are very unreactive.
17. The elements in group_
react very violently with water.
Answer:
14 Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
15 The halogen group of elements is the most reactive of the nonmetals. It is also the most reactive group of all chemical elements. Fluorine is the most reactive element in this group. Halogens are highly reactive because they are all electronegative.
16 Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
17 Group 1: Alkali Metals
Group 1 elements are called alkali metals because of their ability to displace H2(g) from water and create a basic solution. Alkali metals are also known to react violently and explosively with water.
