Yuhan is creating a model of a virus, and she studies the table that outlines the differences between viruses and cells.
Viruses and Cells
Characteristic Virus Cell
Structure DNA or RNA in capsid, some with envelope Cell membrane, cytoplasm; eukaryotes also contain nucleus and many organelles
Reproduction Only within a host cell Independent cell division, either asexually or sexually
Genetic Carrier DNA or RNA DNA
Growth and Development No Yes; in multicellular organisms, cells increase in number and differentiate
Obtain and Use Energy No Yes
Response to Environment No Yes
Change Over Time Yes Yes
Study the table. For which reason do the datasupport the classification of viruses as nonliving?
A. Viruses contain genetic information.
B. Viruses evolve over time.
C. Viruses reproduce inside host cells.
D. Viruses do not take in nutrients.
Answer:
D
Explanation:
The answer is D, even though they also need a host cell to reproduce that is not mentioned in the table so the answer is D.
The data support classifying viruses as nonliving because they do not take in nutrients, lack independent metabolic processes, and cannot grow or develop independently. Option D is correct,
The data in the table support the classification of viruses as nonliving for several reasons. A key point is that viruses do not take in nutrients (Option D), reflecting their lack of metabolic processes and inability to obtain and use energy independently. Viruses also do not grow and develop like living cells, which further indicates they do not possess the full traits of life. Additionally, while viruses can reproduce, they can only do so within a host cell, indicating their dependence on other organisms for replication. In contrast, living cells have the ability to independently divide, grow, develop, obtain energy, and respond to their environment. These distinctions underscore why viruses are classified as nonliving entities.How might the human body be compared to a car bicycle? Need help like now! 15 points <33
Answer:
There are some similarities present between human body and car.
Explanation:
In human body, mechanical work is done with the help of energy while the car moves when energy is present in it. Human body gets energy by eating food while the car gets energy from the burning of fossil fuels such as petrol, diesel and CNG etc. Both human and car used organic compounds for the generation of energy. In human body, movement occurs through legs while in cars wheels used for movement from place to place. In human body, stomach produces energy while in cars, engine generates energy.
“A food chain or food web shows the flow of energy and matter though an ecosystem. Which organisms use the sun’s energy and make it available to other organisms?
Plants, algae, and cyanobacteria use sunlight energy to create organic matter from carbon dioxide as well as water. This marks the start of energy flow during almost all food webs.
What is a food chain?A food chain is a network of links in a food web that begins with producer organisms and ends with a top predator, detritivore, or decomposer species.
A food chain also demonstrates how organisms are related to one another through the food they consume. Each trophic level is represented by a different level of the food chain.
Food chains are significant because they reveal the intricate relationships that exist in ecosystems. They can reveal how each organism is dependent on another for survival.
Food chains also show what happens when there is a problem and a producer or consumer is lost.
Sunlight energy is used by plants, algae, and cyanobacteria to produce organic matter from carbon dioxide and water. This is the beginning of energy flow in almost all food webs.
Thus, this way, the producers use sun’s energy and make it available to other organisms.

Final answer:
Producers, or autotrophs, such as plants, use the sun's energy to create organic compounds through photosynthesis. They are essential parts of food chains and food webs as they make this energy available to other organisms. Producers are crucial for the flow of energy and matter within ecosystems.
Explanation:
The organisms that use the sun's energy and make it available to other organisms within an ecosystem are known as producers, or autotrophs. Producers are typically plants and other photosynthetic organisms that capture sunlight and convert it into chemical energy through the process of photosynthesis. This energy in the form of organic compounds is then passed on to other organisms, called consumers, within the food chain that feed on these producers or on other consumers.
In a food web, these producers form the base and are vital for the flow of energy and matter through the ecosystem. Without producers, other organisms would not have the necessary energy to survive. Thus, producers play a key role in ecosystem dynamics and in maintaining the balance of the food chain and food web.
how could knowing that giraffes are four distinct species change the approach of conservationists or zookeepers who work with giraffes?
Answer:
It would help the zookeeper in their breeding program so as not to interbreed the four different species, but rather to breed each species seperately, so as to keep the giraffe as a whole from population pollution by producing hybrids that do not have much conservation values.
Knowing that giraffes are four distinct species could change the approach of conservationists and zookeepers who work with giraffes by requiring different conservation strategies and breeding programs for each species.
Explanation:Giraffes are now recognized as four distinct species: the southern giraffe, the Masai giraffe, the reticulated giraffe, and the northern giraffe.
This new understanding of giraffes as separate species could change the approach of conservationists and zookeepers who work with giraffes by requiring different conservation strategies and breeding programs for each species.
Conservationists and zookeepers would need to consider the specific habitat requirements, feeding preferences, and social behaviors of each species in order to effectively protect and care for them.

How is the carbon cycle similar to the water cycle?
Answer:
The water cycle uses plants for uptake of water and transpiration from the surface, so that water can be sent to the atmosphere. Carbon cycle uses plants for uptake of CO2, by which it is removed from the atmosphere
Explanation:
The carbon and water cycles are similar as they involve movement and transformation of substances in different reservoirs. Both play crucial roles in maintaining life on Earth.
Explanation:The carbon cycle and the water cycle are similar in several ways:
Both cycles involve the movement of substances through different reservoirs or spheres. In the carbon cycle, carbon moves between the atmosphere, living organisms, and the Earth's crust. In the water cycle, water moves between the atmosphere, bodies of water, and the Earth's surface.Both cycles involve processes that cause the substances to change state. In the carbon cycle, carbon dioxide is taken up by plants during photosynthesis and released during respiration. In the water cycle, water evaporates from bodies of water, condenses into clouds, and precipitates back to the surface.Both cycles play important roles in maintaining life on Earth. The carbon cycle is essential for plants to produce food through photosynthesis, while the water cycle ensures the availability of fresh water for drinking and other activities.Overall, the carbon cycle and the water cycle are interconnected processes that involve the movement and transformation of substances on Earth.

Light-colored moths were selected for on light-colored trees best describes the process that produced one of the ending populations of moths. Hence option D is correct.
What is natural selection?Natural selection is a process by which certain traits or characteristics become more or less common in a population over time, based on their ability to help organisms survive and reproduce in their environment.
This statement refers to the classic example of natural selection in peppered moths, which were studied during the Industrial Revolution in England.
Before industrialization, the majority of peppered moths had light-colored wings, which provided camouflage on light-colored tree trunks, where they would rest during the day.
However, as industrialization caused pollution to darken the tree trunks, dark-colored moths became more visible to predators, while light-colored moths became better camouflaged.
As a result, the light-colored moths were more likely to survive and reproduce on light-colored trees, passing on their light-winged trait to their offspring.
Therefore, option D is the best statement that describes the process that produced one of the ending populations of moths.

explain the factors that would influence how fast echinoderms grow and how big they become
Answer:
Environmental factors and climate conditions affect the growth and how fast they grow.
Explanation:
An echinoderm is an organism (all marine) that has a spiny skin. The word "echinoderm" means "spiny skin." Starfish, sea cucumbers, brittle stars, and sea urchins are examples.
Most echinoderms develop from larvae to adolescent echinoderms by direct, or indirect development. In direct development, the fertilized egg is able to enter juvenile stage without becoming a larva. The juveniles stay close to the parent, and are cared for and looked after.
Echinoderms evolved from animals with bilateral symmetry. Although adult echinoderms possess pentaradial, or five-sided, symmetry, echinoderm larvae are ciliated, free-swimming organisms that organize in bilateral symmetry which makes them look like embryonic chordates.
Echinoderms have adapted to match the colour of their surroundings. Also, to protect and structure their bodies, Echinoderms such as sea urchins have interlocking plates of Calcium Carbonate which form a very hard internal skeleton.

Frogs are said to have “two lives” because they undergo a complete metamorphosis, meaning that they change form completely from one stage of life to another.
What occurs in frog metamorphosis?In their early life, frogs are called tadpoles. Tadpoles live in water and have gills for breathing. They eat algae and other small organisms. As they grow, tadpoles develop legs and lungs. They also lose their gills and become able to breathe air.
When tadpoles are fully grown, they metamorphose into frogs. Frogs live on land and have lungs for breathing. They eat insects and other small animals. The change from tadpole to frog is a dramatic one, and it is why frogs are said to have “two lives.”

Why is it important for DNA to be duplicated exactly before a cell divides?
Answer: DNA replication is important because it creates a second copy of DNA that must go into one of the two daughter cells when a cell divides. Without replication, each cell lacks enough genetic material to provide instructions for creating proteins essential for bodily function. DNA is generally tightly packed into a structure called chromatin.
Explanation:
It is important for DNA to be duplicated exactly before a cell divides because one copy of DNA transfers into the nucleus of the daughter cell.
What is DNA duplication or replication?DNA duplication is also known as DNA replication. A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication.
Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process. All living things replicate their DNA, which is the primary mechanism for biological heredity.
Thus, it is important for DNA to be duplicated exactly before a cell divides because one copy of DNA transfers into the nucleus of the daughter cell.

Why did the most recent storm in
Galetown have the greatest amount of
rain?
Answer:
What caused Galetown to have more severe rainstorms? The lake, warmer weather, and stronger winds all caused the most recent storm to have the greatest amount of rain. The addition of the lake caused there to be more water available to evaporate into water vapor in the air parcel
Final answer:
The greatest amount of rain during the most recent storm in Galetown can be explained by the combination of storm surges, erratic storm pathways, and possibly the effects of climate change leading to increased storminess and enhanced water vapor transport.
Explanation:
The greatest amount of rain during the most recent storm in Galetown can be attributed to several factors. One crucial component is the presence of a storm surge, which refers to the rising of the sea as a result of atmospheric pressure changes and wind associated with a storm. This not only creates immediate coastal flooding but also can contribute to higher rain levels inland.
Furthermore, storms with erratic pathways, such as Hurricane Harvey, can lead to unprecedented rainfall accumulation because they linger in one area and continue to draw and dump moisture. Historical data and recent observations such as the addition of a new color to the National Weather Service's maps for rain in Houston, Texas, in 2017 highlight the enormity of rain from such stagnant storms.
Additionally, there is evidence that climate change may be playing a role in increasing rainfall totals, referred to as storminess, where an increased incidence of major rainstorms has been observed. Moreover, extreme rainfall events depend on the strong horizontal transport of water vapor into the storm from the surrounding atmosphere, which can exceed the atmospheric water vapor's capacity to hold moisture over a given land area.

How are the 3 stages of cell division similar to how new animals are created?
ANSWER NOW WILL BE MARKING BRAINLIEST.
Answer:
Cell divison is defined as the process in which a parent cell split into two or more daughter cells. There are three stages of cell division that includes interphase, mitosis/meiosis and cytokinesis.
In the interphase the proteins, enzymes and cell organelles are formed and at the end of this phase single strand chromosome becomes a double strand carrying genes.
In the meiosis (in sexual reproduction) or mitosis (asexual reproduction) phase, divison of nucleus takes place. Meiosis gives rise to geneticaly different cells due to crossing over while mitosis leads to identical cells .
Cytokinesis occurs cocurrently after meiosis or mitosis in which cytoplasm of a parental cell divides into two daughter cells each with identical chromatin.
Creation of new animals are also undergo these 3 stages of cell division that is interphase, meiosis (eukaryotes)/mitosis (prokaryotes) and cytokinesis. Majority of animals (eukaryotes) undergo meiosis phase because their mode of reproduction sexual and have genetic variation due to crossing over of chromosomes and produces 4 daughter cells at the end cell division.
Hence, the 3 stages of cell division is similar to craetion of new animals.
