Answer:
it improves the growth
Explanation:
cause every fertilizer has artificial nutrients that are tested before use
The statements which describe the impact of the use of fertilizers are it improves the growth of crops and it harms the organisms which live in the oceans. Thus, the correct options are A and E.
What are the effects of fertilizers?A fertilizer is any material of natural or synthetic origin which is applied to the soil or to plant tissues for the supply of plant nutrients. Fertilizers may be distinct from that of liming materials or other types of non-nutrient soil amendments. Many sources of fertilizer which exist are both natural and industrially produced.
Fertilizers boost the crop yields, however the excessive usage of crops has hardened the soil, reduced fertility, also strengthened the insecticides, polluted air as well as the water quality, and emitted the greenhouse gases, creating health and environmental risks.
Therefore, the correct options are A and E.

From a sociological perspective, deviance:
Question 46 options:
A)
originates in society, not in individuals
B)
is an adaptation to the social structures in which people live
C)
needs to be responded to by making changes in society
D)
all of the above
Answer:
B
Explanation:
Deviance is where people don't blend into societal norms and cultures for various different reasons, meaning A cannot be the answer. C is not always applicable, and we can see this in the fact that clearly society isn't changing significantly every time there's someone deviant (or we'd have no need for prisons). This makes D also impossible, leaving the only answer that is plausible to be answer B.
At the end of this phase, two new daughter cells that are exact replicas of the beginning cell will be completed.
A. metaphase
B. prophase
C. telophase
Sort the following events into two categories:________.
1. Carcinogenic—changes that could cause cancer
2. Anti-carcinogenic—changes that could stop cancer
a) activation of cyclin gene expression
b) activation of a phosphatase that affects kinase 3 of the MAP kinase pathway
c) activation of a phosphatase that affects p53
d) activation of DNA synthesis genes
e) blocking GTPase activity of the G-protein α subunit
f) blocking degradation of p53
g) blocking dimerization of PDGF receptors
h) blocking cyclins from binding to cyclin-dependent kinases
Answers:
a) carcinogenic
b) anti-carcinogenic
c) carcinogenic
d) carcinogenic
e) carcinogenic
f) anti-carcinogenic
g) anti-carcinogenic
h) anti-carcinogenic
Explanation:
Cyclins are proteins that regulate the progression through the cell cycle, i.e., the transition of G1 to S phase. It is well known that high cyclin expression may lead to cell proliferation states, which is closely associated with cancer progression. Moreover, the blockage of cyclins may have an anti-carcinogenic effect by inhibiting the progression through the cell cycle. MAP kinases are serine/threonine kinases that regulate the progression through the cell cycle by phosphorylating a variety of substrates during cell proliferation. In consequence, phosphatases that inactivate MAPK kinases (i.e., by dephosphorylation) may have an anticarcinogenic effect. The p53 is a tumor suppressor protein involved in diverse cellular processes including DNA repair, cycle arrest and programmed cell death. This protein (p53) is activated by phosphorylation at target residues and phosphatases inactivate it, thereby the blockage of its degradation may have an anticarcinogenic effect. Oncogene activation (i.e., the expression of oncogenes), may alter diverse cellular processes including DNA replication, and thereby may lead to cancer development. The G-protein α subunit is a GTPase that hydrolyses GTP and thus has a major role in controlling the kinetics of the G-protein signaling cascade. Platelet-derived growth factor receptors (PDGFR) are kinase receptors that play roles in regulating cellular differentiation, cell proliferation and cell growth. PDGFR receptors are present on the surface of normal cells, however, it has been shown that mutations of the PDGFR genes that lead to their high expression lead to uncontrolled cell growth and consequently cause cancer (i.e., by increasing PDGF signaling).

Water molecules will move from the side of higher concentration to the side de of lower concentration until both solutions are isotonic at this point the equilibrium will be reached.
Which base pairs with cytosine (C) in RNA?
Answer:
guanine
Explanation:
The four bases that make up this code are adenine (A), thymine (T), guanine (G) and cytosine (C). Bases pair off together in a double helix structure, these pairs being A and T, and C and G. RNA doesn't contain thymine bases, replacing them with uracil bases (U), which pair to adenine1.
The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)
How do decomposition and synthesis reactions work
to serve the needs of individual cells of your body?
Answer:
Because those chemical reactions help the cell to dispose useless substance after they are used and synthetize substance they need or the body needs through them.
Explanation:
Hello.
In this case, since the overall processes inside the cell are constantly producing and getting rid of several substances such as nutrients, proteins, lipids and other, we can say that decomposition reactions serve as a mechanism that the cell uses in order to obtain energy or dispose a substance that is no longer important for it. Moreover, since the cell is the fundamental part wherein the most of the useful substances the body needs are synthetized, we can infer that synthesis reactions must occur in order to allow the body to perform lots of functions, for instance, proteins associated to the hair or nails growing are synthetized inside the cell via the protein synthesis mechanism.
Best regards.

NEED HELP ASAP!!!!!!!!!!!!!! Place these organisms (I have used the scientific names) in order from the least to most number of cells: Sorex minutus, Homo sapiens, Bacillus anthracis, Sequoia sempervirens. Look up these organisms' names if you don't know what they are.
Answer:
Bacillus anthracis
Sorex minutus
Homo sapiens
Sequoia sempervirens
Explanation:
Cells of different organisms are usually around the same size - so the larger the organism, the more cells.
Bacillus anthracis is a single celled bacteria, so it has the least amount of cells - one.Sorex minutus is a small shrew, so has less cells than a human or giant tree.Homo sapiens are humans - which have more cells than a small shrew.Sequoia sempervirens are huge trees, and likely havethe most cells.This is a type of mushroom called a cremini.

how can you maximize the use of useful materials that you have identified
Answer:
By recycling.
Explanation:
By recycling we can maximize the use of useful materials because in recycling process, the material can not be produced again in the laboratory but will be used in after cleaning process which decreases cost of production on the materials and can be sold at high profit. For example, the plastic bottle can be used again after the recycling process so recycling enables us to use the useful materials maximum times.

which action has the least impact on the environment
The action has the least impact on the environment is using a safe fountain for clean drinking water.
Which action has the least impact on the environment?The action has the least impact on the environment is using a safe fountain for clean drinking water. The plants use sunlight, water, and carbon dioxide to make sugars as well as food. Organisms can be divided into autotrophs and heterotrophs according to their pathway of producing food and energy. Heterotrophs are that organism which depend on another organism for their food and energy. They get their energy from carbohydrate, protein, and fat.
Those organisms that are able to make and produce energy from energy-containing organic molecules such as glucose from inorganic raw material such as water and by using light energy such as sunlight are autotrophs. Plants are the prime autotrophs, they produce their food and energy which is sugar from water, sunlight and carbon dioxide using photosynthesis.
Therefore, The action has the least impact on the environment is using a safe fountain for clean drinking water.
