A virus is a contagious particle that multiplies by "commandeering" a host cell and exploiting that cell's resources to create further viruses.
A virus is composed of a DNA or RNA genome enclosed in a capsid, a protein shell. Some viruses have a membrane envelope on the outside.Viruses come in a wide variety. They have various genome types, distinct forms and architectures, and they infect various hosts.By infecting their host cells and reprogramming them to become virus-producing "factories," viruses spread throughout the body.Points of similarities between viruses and eukaryotic cells are as follows:
Both viruses and eukaryotes have genetic material in the form of DNA.They are covered by an external membrane called envelope. In case of eukaryotes, an external cell membrane and cell wall (in case of plants) is also present which envelops the cytoplasm. Both have a capacity to change or evolve over time.Learn more about viruses here:

5. using unevenly distributed resources; less

6. using over half of all renewable fresh water
sources.
7. Three of these
Humans currently are found to be unevenly distributed and the difference is increasing, using almost half of the Earth's land. Humans also use unevenly distributed resources; less than 20% use over 80% of the energy and over half of all renewable freshwater sources making option 2 the correct answer.
Why are humans currently doing these things?
Humans currently are found to be unevenly distributed due to some factors such as climatic factors, economic factors, political factors, geographical factors, and so on. These factors differ across the world and thereby causing uneven distribution of humans and the factors are either getting better or worse in some parts of the world causing an increase in the differences.The human population is increasing rapidly with the increase in activities like agriculture, raising shelters, and economic expansions, as driven humans to almost half of the Earth's land.Resources are not evenly distributed throughout the world as climate differs and this difference is increasing due to humans concentrating more in areas where the resources are available in abundance. The majority of the population doesn't have access to energy resources.There is a big dependence on water by humans and freshwater resources are overexploited even when we have less than 3% of the world's water is fresh. Freshwater is a renewable resource from sources like lakes, rivers, reservoirs, and underground sources.In summary, the human population is increasing rapidly across the world resulting in using unevenly distributed resources, using over half of all renewable freshwater sources, and using almost half of the Earth's land.

What is a Food web?This consists of the food chains which are present in the ecosystem and it shows the food relationship between organisms.
Plants who are referred to as primary producers are the organisms who possess the most energy due to them undergoing photosynthesis and the food web starts with them which in this scenario is mangrove. This is then eaten by insects and then carp eats the insects.
The tertiary consumers are the ones with the least amount because only 10 percent is transferred from one trophic level to another due to some being lost as heat and during metabolic reactions and an example in this case is American alligator.

Each of your cells, whether you're a rat, tomato, bacterium, or human, will contain DNA (with some rare exceptions, such as mature red blood cells in humans). The genome is a set of instructions that is present in every cell in its entirety. Numerous factors lead scientists to examine DNA: They can determine how the instructions contained in DNA support the healthy operation of your body.

The rna transcript being produced by the rna polymerase is complementary to the template strand of the dna is True.
When necessary, cells may quickly produce a vast amount of protein due to the fact that the same gene can produce numerous identical copies of RNA and that each RNA molecule can direct the production of numerous identical protein molecules. However, the efficiency at which each gene is transcribed and translated can vary, allowing the cell to produce large amounts of some proteins and minuscule amounts of others.In the 5' to 3' direction, RNA polymerase creates an RNA transcript that is complementary to the DNA template strand.

Answer:
dogs. dogssssssßsssssssss
Explanation:
dogssss
Force of contraction decreases, when the skeletal muscle is fully contracting for a long duration because it creates a lag in muscle cycle duration.
What is skeletal muscle contraction?The neuromuscular junction, which is the synapse between a motoneuron and muscle fiber, is just where skeletal muscle contraction begins.
The propagation of nerve impulses to the motoneuron and subsequent depolarization leads the presynaptic membrane's voltage-gated calcium channels to open.
Calcium ions bind to the protein complex troponin, exposing the active-binding sites on actin, and triggering the muscular contraction cycle. Whenever the actin-binding sites are revealed, the high-energy myosin head crosses that gap, resulting in the creation of a cross-bridge.
Therefore force of contraction will decrease in skeletal muscle when contracting for a long duration.

What is color phenotype?A set of an organism's visible qualities or characteristics is referred to as the phenotype in genetics. The phrase includes an organism's morphology, or physical shape and structure, as well as its physiological and biochemical characteristics, behavior, and the outcomes of behavior.
The expression of an organism's genotype, or genetic makeup, and the impact of environmental circumstances are the two fundamental components that determine its phenotype. Both elements may interact, which would further influence phenotypic. A species is considered polymorphic if there are two or more phenotypes that are visibly distinct within the same population. The color of Labrador Retrievers is a well-known case of polymorphism; while the coat color is determined by a number of genes, it is readily apparent in the environment as yellow, black, and brown.

5.88235.10-7 is the energy of an orange lamp with a frequency of 5.10 x 10^14 hz.
What is frequency ?The number of times a repeated event occurs in a given amount of time is known as its frequency. It is also sometimes called "temporal frequency" to stress the contrast to "spatial frequency" and "ordinary frequency" to underline the contrast to "angular frequency." Hertz (Hz), which is equal to one (event) per second, are the units used to express frequency.
The reciprocal of frequency, the period is the length of time occupied by one cycle in a repeating event. The period, T—the space between beats—of a heart beating at a frequency of 120 beats per minute (2 hertz), for instance, is half a second (60 seconds divided by 120 beats). Science and engineering employ frequency as a key characteristic to define the temporal scale.

With a short time remaining in the day, a delivery driver has time to make deliveries at locations among the locations remaining. How many different routes are possible?.
84 different routes are possible for a delivery driver to make deliveries at locations within the outstanding locations.
The notion of combination in this question provides us with a number of alternative methods to organize a selection from a set. It is most commonly employed in probability. The formula for combination is given by:
(nCr)= n!/(n-r)!r!
To figure out how many paths are conceivable, we must first figure out what is available. Because there are only nine remaining places, we use n = 9. We can only accept 6 places; thus we use r = 6. We utilize combination to determine the number of possible routes that the delivery driver might take. (9C6)

Normal trade winds push warm surface water away from the coast of South America. This water is replaced by other seawater in a process called upwelling. Upwelling results in cold and nutrient-rich water along the coastline.
The result is the everyday float of water far away from South the USA decreases and ocean water piles up off the South the USA. This pushes the thermocline deeper and decreases the upwelling. within the tropical western Pacific, weakening or reversal of the alternate winds causes the pool of heat floor water within the western tropical Pacific to glide eastward along the equator closer to the coast of the South us.
This is due to the exchange winds blowing from east to west along the equator allowing the upwelling of bloodless, nutrient-rich water from deeper degrees off the northwest coast of South the united states. also, these identical change winds push water west which piles better inside the Western Pacific.
