Answer:
Certain viral pathogens can lead to death. Viruses like Human Immunodeficiency Viruses (HIV) are not considered lethal on their own but lower your body's ability to fight infections, and over time cause Acquired Immunodeficiency Syndrome (AIDS). If infected by this virus you could be killed by the common cold. That is why it is important to be protected against viral pathogens.
Explanation:
Explain why all diseases are not infectious.

how might a healthy, actively hunting wolf pack impact the elk herd population density?
The elk herd population density will decrease the density by feeding off them, however, if it's a healthy balanced amount.
What do you mean by population density?Population density is the average number of individuals in a population per unit of area or volume. For example, a population of 100 insects that live in an area of 100 squar e meter s has a density of 1 insect per square meter.
The number of individuals living within that specific location determines the population density, or the number of individuals divided by the size of the area. Population density can be used to describe the location, growth, and migration of many organisms
To calculate density, you divide the number of objects by the measurement of the area. The population density of a country is the number of people in that country divided by the area in square kilometers or miles.

Which statement is correct regarding the semiconservative nature of DNA?
A. RNA operates as a template to allow DNA to replicate itself using ribosomes
B. Nitrogenous bases in each "parent" strand serve as a template for the new strand to be made
C. The semiconservative nature of DNA allows for genetic continuity in gamete production
D. The structure of the sugars on the DNA molecule direct the correct nucleotides into place during replication
I need the answer fast, this is a 40 point and i will put you as brainliest
Answer:
B. Nitrogenous bases in each "parent" strand serve as a template for the new strand to be made
Explanation:
DNA replication is the process whereby the contents of DNA is doubled or duplicated. In other words, another copy of DNA is produced from one DNA molecule. The process follows the semi-conservative model, which generally speaks of how one template strand is used to synthesize another new strand.
In the semi-conservative model of DNA replication, the double strand of DNA is unwind and one of the strands called parent strand is used synthesize a complementary strand of DNA. At the end of the process, two DNA molecules results with each having one old strand and one new strand. Nitrogenous bases or nucleotides in each "parent" strand" serve as a template for the new strand to be made.

In the deep water where there is no sunlight, how do bacteria and plants create
their food?
Answer:
Bacteria and Plants use the process of chemosynthesis to create/make food using chemical reactions.
Explanation:
"Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen. ... Bacteria that live in the deep ocean, near hydrothermal vents, also produce food through chemosynthesis."
