Which type of muscle is paralyzed when its nerve supply is absent?
A. Striated involuntary muscle
B. Nonstriated involuntary muscle
C. Striated voluntary muscle
D. Nonstriated voluntary muscle
Answer:
C. Striated voluntary muscle
Explanation:
Striated voluntary muscles are the skeletal muscles that are responsible for the voluntary muscular movements that take place in the body.When the body becomes paralyzed than a person loose his/her ability to utilize this motor muscles as it lacks nerve supply due to some injury. Therefore the muscle that is affected is the striated voluntary muscles.When a person removes co2 from the lungs by exhaling, the person also removes __________ from the blood?
When a person removes CO2 from the lungs by exhaling, they also remove carbon dioxide from the blood.
Explanation:When a person removes CO2 from the lungs by exhaling, they also remove carbon dioxide from the blood. Carbon dioxide is transported in the blood from body tissues to the lungs by several methods, including dissolution directly into the blood, binding to hemoglobin, or being carried as a bicarbonate ion. When the blood reaches the lungs, the dissolved carbon dioxide diffuses across the respiratory membrane into the alveoli, where it is then exhaled during pulmonary ventilation.

What is significant about the symbiosis between mycorrhizae and the plants known as ghost pipe and garlic mustard?
Final answer:
The symbiosis between mycorrhizae and plants like ghost pipe and garlic mustard is essential for nutrient acquisition and plant growth, with the ghost pipe relying completely on this association due to its lack of chlorophyll, and garlic mustard potentially disrupting mycorrhizal relations of native plants in invaded areas.
Explanation:
The symbiosis between mycorrhizae and plants like ghost pipe and garlic mustard is significant because it represents a mutualistic relationship that is crucial for the survival and growth of these plants. Mycorrhizae are a type of fungus that form associations with plant roots, enhancing water and mineral nutrient absorption. Through this relationship, the plant gains improved access to nutrients, particularly in nutrient-poor soils, while the fungus receives sugars and other photosynthetic products from the plant.
The ghost pipe, also known as Monotropa uniflora, is especially interesting because it lacks chlorophyll and so depends entirely on the mycorrhizal relationship for its nutrition, drawing upon the nutrient reserves of the mycorrhizal network. Garlic mustard, on the other hand, may affect the mycorrhizal associations of native plants negatively when it invades an area, thereby impacting native plant communities and ecosystem dynamics. Understanding these interactions is critical for conservation and management of native plant species and their habitats.

Which trna anticodon(s) could decode the mrna codon cag (recall that codons are always written in the 5'—>3' direction and anticodons are written in the 3'—>5' direction)?
The tRNA anticodon that can decode the mRNA codon 'CAG' is 'GUC' as it is complementary to the mRNA codon.
Explanation:The mRNA codon 'CAG' would be decoded in the process of protein synthesis by a tRNA anticodon which is complementary to it. Since in RNA, Adenine (A) pairs with Uracil (U) and Cytosine (C) pairs with Guanine (G), the anticodon that matches with the 'CAG' codon will be 'GUC'. Thus, the tRNA anticodon that can decode the mRNA codon 'CAG' is 'GUC'.

The two major UNIX system versions are the UNIX System V and the AT&T UNIX. UNIX System V is the evolutionary outcome of a developmental project at the AT&T Bell Laboratories. BSD UNIX is a subsidiary version, which began with an early spread of AT&T UNIX by computer science students at the University of California at Berkeley.
The two major versions of UNIX are BSD, which is known for its fast filesystem and TCP/IP network stack, and System V, which is known for its support for multiple processors and an easier to navigate file system hierarchy.
Explanation:The two major UNIX system versions are BSD (Berkeley Software Distribution) and System V. Both of these versions have influenced the development and evolution of Unix and Linux operating systems over the years.
BSD is derived from the version of UNIX developed at the University of California, Berkeley. It is known for its TCP/IP network stack and the fast filesystem. It has further evolved into systems like FreeBSD, OpenBSD, and NetBSD.
On the other hand, System V is derived from the version of UNIX that was developed by AT&T. This version introduced features like support for multiple processors and a file system hierarchy that was easier to navigate. It has influenced the creation of modern Unix systems like AIX, HP-UX, and Solaris.

What advantage do you think a protist would gain by having a unicellular, filamentous, or colonial form?
Final answer:
Protists can gain advantages such as efficient nutrient absorption, attachment to substrates, and division of labor by having different forms like unicellular, filamentous, or colonial.
Explanation:
A protist can gain several advantages by having different forms such as unicellular, filamentous, or colonial.
Unicellular protists have a higher surface area to volume ratio, which allows for efficient nutrient absorption and waste elimination. They can also reproduce quickly and adapt to changing environmental conditions.
Filamentous protists, like bacteria, can form long chains of cells that enable them to colonize surfaces and attach to substrates. This helps them access resources and form protective barriers.
Colonial protists can benefit from collective behavior and division of labor within the colony. Some cells can specialize in reproduction, while others carry out specific functions like locomotion or feeding.

The ER (endoplasmic reticulum) can be defined as an eukaryotic cell organelle, which makes interconnected network of membrane-bound, flattened sac-like structures. These structures are known as cisternae
The endoplasmic reticulum can be divided into two types, on the basis of presence or absence of ribosomes. The smooth ER does not ribosomes on its surface, while rough ER carries ribosomes on its surface. These ribosomes are known as protein-manufacturing units of cells.
Thus, the correct answer is option (C).
unlike most of the disorders of childhood and adolescence, the causes of eating disorders are disproportionately related to ____ influences.
Eating disorders like anorexia and bulimia nervosa, unlike other disorders of childhood and adolescence, are strongly influenced by cultural factors. Especially prevalent among White Western females aged 15-19, these disorders connect to societal values around thinness, portrayed in media and fashion. Although genetics may predispose some individuals to these disorders, the contribution of cultural influences is significant.
Explanation:Unlike most of the disorders of childhood and adolescence, the causes of eating disorders are disproportionately related to cultural influences. Both anorexia and bulimia nervosa occur across cultures, but White females from Western societies, mainly aged 15-19, are much more prone to them. These disorders are linked strongly to a thin ideal prevalent in popular media and fashion industries in these societies.
Eating disorders also have a genetic component, suggesting that some individuals may be predisposed to these disorders. Hence it's a combination of genetic predisposition and social pressures emphasizing thinness that contribute largely to the development of eating disorders. While biological factors normally play a vital role in other childhood and adolescence disorders, cultural factors play a key role in eating disorders.

Scientists predict that global warming could cause _____.
Scientists predict that global warming could cause extensive environmental and societal impacts, including more extreme weather, loss of biodiversity, rising sea levels, and increased human violence due to resource shortages.
Scientists predict that global warming could cause a wide array of impacts. These include the continued retreat of glaciers, greater weather extremes, and the expansion of deserts. Other significant changes forecasted due to global warming are shifts toward the poles in natural habitats, loss of biodiversity, modifications in food production, and rising sea levels, leading to displacements of human populations. Additionally, there may be increases in human violence because of exacerbated environmental stresses, such as water shortages and reduced agricultural yields.
Specifically, future global warming could result in more powerful storms, droughts, and altered precipitation patterns which can affect agricultural zones and cause food shortages. Severe hurricanes and tornadoes are also likely to increase due to more solar energy in the oceans and atmosphere. The melting of land glaciers, particularly the Greenland ice sheet, contributes to rising sea levels, which is a severe threat to coastal communities.
In the long term, warming greater than 5°C could potentially lead to an ice-free Earth, causing drastic sea-level rises. Such outcomes can pose serious threats to food and water resources, affecting the survival and habitation of billions of people. Overall, while there may be some isolated benefits to milder climates in certain regions, the net effect of global warming is widely considered detrimental, and potentially catastrophic, to our planet's ecosystems and human societies.
