The diagram below shows a type of virus called a bacteriophage. Select the name of the structure that the virus can use inside a host cell to produce new virus particles.
Answer:
It's the DNA..........
The structure that the virus can use inside a host cell to produce new virus particles is the DNA.
Bacteriophage which literally means bacteria eater is a type of virus that has the ability to infect bacteria.
Basically all bacteriophages consist of nucleic acid molecule (DNA) which is surrounded by a protein coat( the capsid head).
It also possess a tail sheath through which it transfers it's DNA into host cell.
Eventually, new bacteriophages assemble and burst out of the bacterium in a process called lysis.
Therefore, the structure that the virus can use inside a host cell to produce new virus particles is the DNA.

Which pair is correct?
a. G2 phase, preparation for mitosis
b. G1 phase, DNA replication
c. M phase, cell growth
d. S phase, cell division
A pair that is correct with respect to the cell cycle is the G2 phase, preparation for mitosis.
What do you mean by Cell cycle?The Cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next.
In the G1 phase of the cell cycle, the cell grows in size and synthesizes mRNA as well as proteins which are required for DNA synthesis.
M-phase governs the nuclear division (Karyokinesis), and cytoplasm division ( cytokinesis).
S-phase is known to double the amount of genetic content within the cell.
Therefore, a pair that is correct with respect to the cell cycle is the G2 phase, preparation for mitosis.

Explanation:
A food chain always starts with a producer, which is an organism that makes food. This is usually a green plant, because plants can make their own food by photosynthesis. A food chain ends with a consumer, which is an animal that eats a plant or another animal.
Green plants are producers
They are the first link in all food chains
Plant cells contain chlorophyll and can photosynthesise
Photosynthesis produces glucose and oxygen
Animals are consumers
If they eat plants, they are the first-order consumers or herbivores
The chemical energy in the green plants is transferred to the animal when it eats the plant .
A student made a model of an ecosystem inside a sealed plastic bottle. She
placed soil, rocks, water, plants, and animals inside the bottle. How is the
model unlike a natural ecosystem?
A. The model has more consumers than a natural ecosystem.
B. The model lacks the producers found in a natural ecosystem.
C. The model has more predators than a natural ecosystem.
D. The model lacks the diversity found in a natural ecosystem.
The model lacks the diversity found in a natural ecosystem.
What is a natural ecosystem?A natural ecosystem is made up of living and non living parts. Energy is cycled in the system along the food chain from one organism to another.
Thus the model that is made by the student is unlike a natural ecosystem in the sense that the model lacks the diversity found in a natural ecosystem.

Define biodiversity and the importance of diversity in ecosystems. How could humans harm an ecosystem's biodiversity?
Answer:
Biological diversity - or biodiversity - is the term given to the variety of life on Earth and the natural patterns it forms. The biodiversity is the fruit of billions of years of evolution, shaped by natural processes and, increasingly, by the influence of humans.
Explanation:
Biodiversity is important to humans for many reasons. ... Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. If no changes are made in the ways humans use resources on earth, there will continue to be a degradation of biodiversity until human lives can no longer be sustained. Humans affect biodiversity by their population numbers, use of land, and their lifestyles, causing damage to habitats for species.

Which statement is not an example of how the use of resources has changed?
A. More products are made from recycled materials.
B. Cars still largely rely on oil.
C. Car companies have developed hybrid cars.
D. More wind farms are present in the United States.
Answer:
B. Cars still largely rely on oil.
Explanation:
Nowadays, most countries still use transportation systems that burn fossil fuels. An example of this may be private cars that consume gasoline, which derives from fossil fuels (oil). The use of fossil fuel transportation systems increases the emission of carbon dioxide (CO2), a major greenhouse gas involved in global warming. In the near future, it is expected that fossil fuel-based vehicles can be replaced by electric cars that use energy obtained from renewable sources (e.g., solar energy, wind energy, etc).

Since pesticides run off from
several farms and fields can make its
way to are waterways such as rivers,
lakes, and oceans, what type of pollutant
are they considered to be?
I know this is supposed to be a question but the answer is a Non-Point solution.
Answer:
It can also clog the gills of fish or smother fish larvae. In addition, other pollutants like fertilizers, pesticides, and heavy metals are often attached to the soil particles and wash into the water bodies, causing algal blooms and depleted oxygen, which is deadly to most aquatic life.Nutrients like nitrogen and phosphorus are essential for growing crops, but they can also trigger algal growth in rivers, lakes and bays. Agricultural runoff flows into the lakes and rivers that hundreds of towns draw their water from.Runoff picks up fertilizer, oil, pesticides, dirt, bacteria and other pollutants as it makes its way through storm drains and ditches - untreated - to our streams, rivers, lakes and the ocean. Reducing runoff can help prevent water pollution, reduce flooding, and protect our precious drinking water resources.
Explanation:
Stormwater runoff can also wash sediment, nutrients or other pollutants into water sources. Increased sediment, nutrients and other pollutants can diminish water quality, threaten drinking water sources, and complicate water treatment processes.

B some evidence can not be collected
C some evidence does not last / is temporary
D once evidence is used in court it is thrown away, and photographs allow CSI to study evidence years later
the answer would be d hope thos helps
The one that is not a reason to take photographs of a crime scene is once evidence is used in court it is thrown away, and photographs allow CSI to study evidence years later. The correct option is d.
What is an evidence?They photograph and physically measure the scene, identify and collect forensic evidence, and keep the evidence in the proper chain of custody.
Fingerprints, footprints, blood and other bodily fluids, hairs, fibers, and fire debris are all gathered by crime scene investigators all are included.
While the most obvious goal of crime scene photography is to create a visual record of the crime scene and all of its relevant features, the best example of photography's role is the presentation of a logical story.
The one reason not to photograph a crime scene is that the evidence is used in court, it is discarded, and photographs allow CSI to study evidence years later.
Thus, the correct option is d.
