a) violate the first law of thermodynamics.
b) decrease their entropy while increasing the entropy of the universe.
c) are only compelled to follow the first law of thermodynamics
d) are examples of a closed system
e) violate the second law of thermodynamics
Living systems are examples of a closed system, as they have an organism and unit configuration.
What is a closed system example?A closed system is one in which only energy is transferred and not any matter. Earth is considered the best example of a closed system as it only transfers energy and not matter around its atmosphere. And it is a natural process that is happening in and around the Earth.
With this information, we can conclude that Living systems are examples of a closed system, as they have an organism and unit configuration.

do you think the biodiversity is as high in a city park as it is in a rainforest?why or why not?
No, the biodiversity is not as high in a city park as it is in a farm or rainforest
because, in an urban city park, only the species with the most general habitat and resource requirements have generally remained in the urban park.
What is Biodiversity ?“Biodiversity” not only refers to the number of individual species, but also the genetic variety within and between species and the diversity of ecosystems and regions.
City Parks are less likely to have biodiversity richness as compared to a farm or a rainforest.This is because these parts are artificially created and a lot of naturally occurring flora and fauna are modified in the process.

What conditions make for a violent volcanic eruption?
A. Magma with low gas content
• B. Magma with high silica content
• C. Magma with low viscosity
•
D. Magma that can flow easily
Answer:
B. Magma with high silica content.
Explanation:
Too explain, magma with high silica context has very high viscosity which is perfect for a volcanic eruption to be formed (a very violent at that).
In each magma, there is always some type or degree of gases trapped such as carbon dioxide (CO2) and water (H2O).
This means the more gases trapped, the increase in the violence of the explosion.
So the silica content in magma overall control or determines how thick it is, the easiness of it's flowing, and how quickly dissolved gases that are trapped in the magma can be released. Due to these reasons, it can therefore be shown that the silica content of magma overall determines whether the eruption is violent or not. It would also determine the shape and size of the produced (resulting) volcanic cone.
So with Option B, due to the magma having high silica content, it has the right conditions for a violent volcanic eruption. Therefore, Option B. Magma with high silica content is correct.

Virioids are irresistible specialists that comprise just of bare RNA with next to no defensive layer, for example, a protein coat. Viroids contaminate plants and are reproduced to the detriment of the host cell. Viroid genomes are little single-stranded circles of RNA that are just 250-400 bases in length.
A prion is a "proteinaceous infectious particle," a name that was abbreviated to "prion" simply a protein.

The cell will initially depolarize, but repolarization will be considerably more difficult because it solely uses ion pumps.
How will the action potential affected and remove external K+? There will be an increase in the membrane potential. Na+ leaves the cell along a gradient of concentration, reflecting an early outward current.It makes the falling phase possible, enabling the action potential to complete its cycle.Action potentials are produced when certain ions pass the neuronal membrane. A stimulation causes the sodium channels to initially open.

At the molecular level, cells from different types of organisms vary in their tolerance to temperature and pH. This variation can mostly likely be attributed to the types of enzymes present in the cells.
The tolerance ranges for abiotic environmental factors are similar to the geographic ranges that organisms have. To put it another way, they can tolerate (or survive in) a specific range of a given factor, but they cannot survive if the element is present in either an excessive or insufficient amount. Take temperature, for example. Polar bears thrive in cold climates but would perish in the tropics from excessive heat.Cells are incapable of acting as "liquid machinery" at temperatures below freezing and above boiling.

An organism with genotype aabbcc will produce only one type of gamete i.e., abc.
An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype. Eye color is encoded by a gene. The allele in this instance can either be brown or blue, with one coming from the mother and the other from the father.every letter represents an allele, hence a, b and c are different alleles on the same locus. all alleles exist in pairs hence this makes up the genotype as aabbcc.on crossing two individuals with genotype aabbcc the following results are obtained:aabbcc X aabbcc

Air that is present in the conducting airways, in terms of volume is the anatomic dead space.Inhaled air entering this area of the lung cannot participate in gas exchange because alveolar capillaries are blocked (e.g., by a pulmonary embolism), therefore it behaves just like air entering the conducting airways. The amount of respiratory zone air that is not involved in gas exchange, known as physiologic or total dead space, is equal to anatomic plus alveolar dead space. The respiratory bronchioles, alveolar duct, alveolar sac, and alveoli make up the respiratory zone.The figure shows empty space.
