Answer:
why is it important
Healthy marine ecosystems are important for society since they provide services including food security, feed for livestock , raw materials for medicines, building materials from coral rock and sand, and natural defenses against hazards such as coastal erosion and inundation.
How does it effect humans:
Recreation, tourism and water transport are familiar services provided by many marine ecosystems. Some unique estuarine, coastal, and marine habitats are also important stores of genetic material and have educational and scientific research value as well.

Seth will attend college in the fall and live in the dormitory, so he is required to obtain a blank against bacterial meningitis, which will stimulate his body to produce immunity to the disease. He reads that meningitis is a fast-acting and potentially fatal disease, transmitted by blank in the respiratory droplets of infected individuals. The bacteria are blank that cause disease by destroying blank and releasing blank that disrupt the body’s normal homeostasis. Bacterial infections are treated with blank , which block the growth and reproduction of bacteria.
Key answer: bacteria, vaccine, cells, pathogens, toxins, antibiotics
Answer:
vaccine
bacteria
pathogens
cells
toxins
antibiotics
Explanation:
Bacterial meningitis is a serious disease that is caused by an infection which results into Inflammation of brain and spinal cord membranes.
It is generally caused by virus but also caused by fungus and bacteria. A vaccine is required to fight against the bacterial meningitis. Symptoms include fever, stiff neck and headache. This disease is carried by the bacteria present in the throat of infectious person and can transmit through coughing, sneezing and kissing. The bacteria are the pathogens, releases a toxin which destroy cells and surface components of nervous system.
This disease is treated with intravenous antibiotics and corticosteroids (sometimes).
Hence, the correct answers for blanks are vaccine, bacteria, pathogens, cells, toxins, and antibiotics in sequential order.

A marine ecologist has constructed the conceptual model shown in the diagram. Which prediction can be made from using this model?
Hello. This question is incomplete. You forgot to put the diagram and answer options.
The diagram is in the figure attached below and the answer options are:
Where the tertiary consumers get their energy
How often primary producers are able to reproduce
When bacteria and fungi initiate the process of decomposition
Whether other secondary consumers are present
Answer:
Where the tertiary consumers get their energy
Explanation:
The diagram establishes the visualization of a food network where it is possible to visualize all the relationships between predators and game, in addition to being possible to observe the relationships between each trophy within a food chain.
With this, it is possible to determine all the ways that tertiary consumers are able to obtain energy and observe how that energy reached them.

what would happen if a new predator was introduced into the ecosystem that only ate mice ? Would the mouse population be lowered ?What else would happen because of this
Answer:
The mice population would be lowered, and that predator could be a prey to other predators in that environment.
Explanation:
The introduction of new predator has both positive as well as negative effects on the ecosystem and environment.
What happen when the predator in introduced in an ecosystem?If a new predator was introduced into the ecosystem that only ate mice so this results in the reduction of population of mice which leads to the disturbance of the ecosystem.
So we can conclude that introduction of new predator has both positive as well as negative effects on the ecosystem and environment.

After removing a cutting from a parent plant, farmers usually:
Answer:
Plant the cutting in a different location
Explanation:
A cutting is a piece of a plant that is usually cut by farmers during agricultural practices. It is a means of vegetative (asexual) propagation.
The part of the plant which is cut is usually the stem or root of the parent plant. The cutting is then placed in a favorable environment which is mostly moist soil for proper growth .

What is a Schwarzchild radius and what does it have to do with a black hole
Answer:
The Schwarzschild radius (sometimes historically referred to as the gravitational radius) is a physical parameter that shows up in the Schwarzschild solution to Einstein's field equations, corresponding to the radius defining the event horizon of a Schwarzschild black hole
Explanation:
The Schwarzschild radius define the “size” of a black hole. Theorists believe that all the “stuff” inside a black hole collapses into a singularity, an infinitely small and infinitely dense point well inside the boundary defined by the Schwarzschild radius.

Consider the food web seen here. One member, the northern spotted owl, lives in cavities of trees in old-growth forests. Old
growth forests contain trees that are more than 200 years old and have not been cut, pruned, or managed. Imagine that these
forests have been heavily logged, Predict the outcome on this food web if the habitat of the owl is removed
AY
The food web will collapse without this top-level consumer present
B)
The niche filled by the owl will be filled by other predators like the hawk
and fox
The niche filled by the owl will be empty. The other animals within the
food web will grow unchecked.
Without the owl present, the empty niche will result in an overpopulation
of hawks. Eventually the lower-level consumers will disappear
DY
Answer:
I'm pretty sure it is the third option: The niche filled by the owl will be empty. The other animals within the food web will grow unchecked.
Explanation:
The owl is a predator animal. As it hunts small prey, it keeps the population of those prey animals stable. If the owl is taken out of the habitat, then the population of the prey animals it used to hunt will grow out of control.
The niche filled by the owl will be empty. The other animals within the food web will grow unchecked.
What is a food web?All the food networks in a single ecosystem make it into a food web. Each organism in an ecosystem is a link in a number of food chains. Energy and nutrients can go along different food chains as they move through the environment. A food web is made up of all the linked and overlapping food systems in an ecosystem.
The trophic levels are divisions into which organisms in food webs are categorized. These levels can be roughly categorized as producers (first trophic level), consumers (second trophic level), and decomposers (final trophic level).
The first trophic level is producers. Producers often referred to as autotrophs, produce all of their own food and do not rely on any other living thing for sustenance. The majority of autotrophs convert sunlight, carbon dioxide, and water into food (a nutrient called glucose) through a process known as photosynthesis.
The most well-known form of autotroph is a plant, but there are numerous others as well. Algae are autotrophic, and their bigger forms are known as seaweed. Autotrophs include the small sea life known as phytoplankton. Autotrophic bacteria include certain varieties. For instance, microorganisms that live near active volcanoes make their own food by using sulfur rather than carbon dioxide. Chemosynthesis is the name of this process.
Therefore, The niche filled by the owl will be empty. The other animals within the food web will grow unchecked.

preventing damage to crops from precipitation
ensuring improvement of environmental health
relocating ecosystems away from polluted areas
Answer:
Protecting different kinds of wildlife.Restoring vegetation in certain areas.Ensuring improvement of environmental health.Relocating ecosystems away from polluted areas.Explanation:
These are all the factors that are included in watershed conservation. Watershed conservation is very important to the environment for several reasons. Freshwater from the watershed is often used by people for the purposes of drinking, cleaning and bathing. Conserving this source allows us to avoid the depletion of freshwater supply. Moreover, it is important to ensure that such water is not polluted, both for the benefit of humans, as well as to ensure that plants and animals that require this water are able to access it safely.

of her gametes will carry the allele for dimples?
A. 0%
B. 25%
C. 100%
D. 50%
Answer:
50%, i believe
Explanation:
So the mother in the problem must have gotten her alleles from her mother and father. Who donated what we are not sure. All we know is that she got one allele for dimples and one allele for no dimples. These are part of the mother's somatic cell DNA. This DNA is duplicated during interphase, right before meiosis occurs as the mother begins to form her gametes, however.
