Answer:
See explanation
Explanation:
Nitrifying bacteria convert the most reduced form of soil nitrogen, ammonia, into its most oxidized form, nitrate(Science direct).
Nitrifying bacteria converts ammonia to nitites and finally to nitrates in the soil.
Hence, when 30 g of ammonia, nitrate and nitrite are added to a soil sample in the presence of nitrifying bacteria; the concentration of ammonia decreases over time while the concentration of nitrite and nitrate increases over time.
ammonia stays the same
nitrates decrease
nitrates increase

All of the following are functions of asexual reproduction except _____.
growth
producing gametes (sex cells)
making new organisms
replacing old or damaged cells or tissues
All of the following are functions of asexual reproduction except producing gametes.
What do you mean asexual reproduction?Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.
Asexual reproduction is a type of reproduction in which only one parent is involved. There are basically 5 types of asexual reproduction. These are binary fission, budding, vegetative reproduction, fragmentation and by spores.
The major disadvantages of asexual reproduction are: Lack of diversity- Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent.

Answer:
Multiple organisms may be affected by the loss of a plant species
Explanation:
If a organisms food source were to vanish, it would affect the herbivores that feed on that plant, but also the carnivores/omnivores that feed on the herbivores. Because the herbivores will die as a result from not having food. This will also lead to the carnivores/omnivores to die.
A woman bought 10 crates of eggs from the market. On getting home, she realized that 15 eggs were broken. What is the ratio of broken eggs to unbroken eggs.
Answer:
B:U = 1:20
Explanation:
Let the number of broken eggs be B.
Let the number of unbroken eggs be U.
Given the following data;
Number of crates of egg = 10 crates
But, 1 crate of egg = 30 eggs
10 crates of egg = 30 * 10 = 300 eggs
B = 15 eggs
U = 300 eggs
Ratio B to U = B:U
B:U = 15:300
Dividing by 15, we have;
B:U = 1:20

Which is NOT a function of the stem in plants?
O Store water
O Carry nutrients
O Provide support to the plant
O Anchor the plant in the ground
Answer:
yes D is the answer
Explanation:
cuz steam store water carry nutrients and of course provide support to the plant
Stems are the part of the plant and the structural axes that help in support and transport. The stem does not anchor plants to the ground.
What are stems?Stems are the axis of the plant that bears shoots, leaves, buds, flowers, etc. The stem of the plant conducts water and mineral through the vascular system of the xylem and phloem.
The roots of the plant provide an anchor to the stem. They also store food and water in their structures that are used for further use and make them available at the time of requirement.
The stems are the mechanical structure that provides support to the plant parts and enables them to stand upright.
Therefore, option D. anchor to the ground is not provided by the stem.

Use your understanding of prevention and treatment of viruses to answer the questions below.
A
is a substance containing incomplete portions of a virus that produce an immune response when injected into the body.
I'm a bit confused about this question. But I will try my best to answer. :)
To prevent a certain virus, or increase someone's immunity towards a virus, doctors give patients a shot/vaccine. For example, people get a flu shot yearly to help prevent them from getting the flu. The shot contains a small portion of the flu itself. The flu remains dormant until the body decides to activate it or fight it off. This also helps the body become more immune to the virus/sickness and fight it off easier.
I hope this helps! :)
A hapten is a substance containing incomplete portions of a virus that produce an immune response when injected into the body.
What is the Immune response?The immune response may be defined as the type of reaction that occurs in response to specific antigens or foreign agents. Such types of responses defend the organism against foreign invaders.
A hapten is essentially an incomplete antigenic particle. Such small substances or molecules only elicit an immune response when attached to a carrier known as proteins.
Carrier molecules typically do not elicit an immune response by themselves.
Therefore, it is well described above.

why would you expect Greenland to have a higher albedo than its surrounding areas?
The albedo of the ice sheet is high in winter when much of Greenland is covered by fresh snow.
Greenland is filled with ice and has a higher reflectance rate as in winters it's covered with fresh snow.
Where is Greenland?The greenland is an island nation and lies between the arctic and Atlantic ocean. Has an area of 2.166 million square km and is among the largest island in the world.
It has the third-largest area in North America after Canada, The lowest temperature is recorded in Greenland in the northern hemispheres. Greenland is Greenland snow is thick and fresh in winter this creates a higher albedo.

Sustainable forestry: seeks to conserve forests for the long-term commercial harvest of timber and non-timber forest products by maintaining a mix of forest trees, by age and species, rather than imposing a monoculture. due to the complexity of goals, is most effective when it involves cooperation among environmentalists, loggers, farmers, indigenous peoples, and local, state, and federal governments. approaches vary from one forest ecosystem to another, in response to different environmental, cultural, and economic conditions. is all of the above.
Answer:
Yes, it is all of the above.
Explanation:
Yes, all the above statements are necessary for sustainable forestry because trees and other wild plants of the forest are necessary for all farmers, loggers, environmentalists, indigenous peoples and for the governments. The environmentalists study on these plants to find out the impact of these different plants on the environment, the farmers cultivate trees and plants to get money by selling it, the employment of loggers also related to these forests and the indigenous peoples also gain benefits by gaining food as well as medicines from it. This forest also fulfill the needs of wood and other products of the country.
Which type of rock is shown in each of these photographs?
In the first image, a sedimentary rock is seen. Sand, mud, and gravel deposits build up over time to produce sedimentary rocks. Typically, these sediments are laid down in layers throughout time, and after being crushed and cemented together, they solidify into rocks.
Due to the variety of sediments that make up sedimentary rocks, these rocks frequently have a layered look. In the second image, an igneous rock is seen. When molten rock, or magma, cools and hardens, igneous rocks are created.
Numerous processes, such as the cooling of lava on the Earth's surface or the crystallisation of magma deep below the Earth's crust, can lead to the formation of these rocks.
