7. In an abandoned field, the gradual replacement of grasses by shrubs and then by trees is known as A) predation B) saprophytism C) ecological succession D) transfer of energy
Answer:
C. Ecological Succession.
Explanation:
A is incorrect because predation is the act of an animal preying on another animal for food which has nothing to do with grass and trees. B is incorrect because saprophytism is the ability of certain plants to live in dead or decaying organic matter. For example, imagine mushrooms growing on decaying trees. That still doesn't explain what the REPLACEMENT of grasses, bushes, and trees are called. D is incorrect because that is energy transferring to another, that answer wouldn't make sense. From what I know, ecological succession is the process of change in the species structure of an ecological community over time. So, if there is an abandoned field but grasses and trees are slowly popping up there over time (There's a lot more to it) then C, ecological succession is your answer.
Hope this helps! :3
Which product of photolysis is needed for the continuation of the light reactions?
Answer:
Here, NADP+ is the final electron acceptor, which becomes reduced to NADPH. Meanwhile, ATP is also formed. Therefore, these light reactions release oxygen as a waste product of photosynthesis, while ATP and NADPH are essential to the next step in photosynthesis, the dark reactions.
What are two of the products of the Krebs cycle?

Two samples of radioactive material from the same rock is prepared for testing. Sample A is cut into a 2 inch cube. Sample B is crushed into a fine powder. Compared to the half-life of the material in Sample A, the half-life of the material in the powdered Sample B is:
Answer:
The same
Explanation:
Half life is the time taken for the number of atoms in a radioactive sample to decrease to half of the initial number of atoms. It is also the time taken for the activity of a radioactive sample to decrease to half of its original value.
If samples A and B were obtained from the same rock, then they contain the same number of atoms having the same initial activity even though the samples were not prepared in the same way for analysis.
Hence, samples A and B have the same half life.

What percentage of the human body is made up of water?
A) 10%
B) 30%
C) 50%
D) 70%
E) 90%
Answer:
According to question,Option D is the correct
Explanation:
Up to 60% of the human adult body is water. According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.
Which structure provides a link between the nervous and endocrine systems?

Answer:
denitrification
Explanation:
Denitrification occurs when N is lost through the conversion of nitrate to gaseous forms of N, such as nitric oxide, nitrous oxide and dinitrogen gas. This occurs when the soil is saturated and the bacteria use nitrate as an oxygen source. De-nitrification is common in poorly drained soils.
Which statement best predicts why a cell's progression through the cell cycle might be halted by the G1/S checkpoint?
Answer:
The missing options are:
A. Spindle fibers have not correctly attached to chromosomes.
B. Damage occurred to DNA when it was being copied in G1.
C. There are not enough nucleotides available to construct new DNA.
D. Proteins necessary for M phase of the cell cycle have not been produced.
The correct option is C.There are not enough nucleotides available to construct new DNA.
Explanation:
During the G1 phase, the cell grows in size since it prepares its organelles and molecule combinations for the next phase of the cell cycle, the S phase. Before the cell transitions to the S phase, it has to pass through a checkpoint that makes sure that there are no mutations, it has grown enough, and has the necessary molecules for the next phase, which is the synthesis of DNA. If there are not enough nucleotides, the cell will not be able to synthesize new DNA in the S phase, so the checkpoint stops the cells from moving to this phase till it has all the necessary things to do it.

explain why giving antibiotics to animals can affect human health
Answer:
Abstract. The use of antibiotics in food animals selects for bacteria resistant to antibiotics used in humans, and these might spread via the food to humans and cause human infection, hence the banning of growth-promoters.
Explanation:
why is being able to convert one energy form to another so important for us to do? please explain your answer in complete sentences.
Energy is the fundamental need of our everyday life. ... This means that we can convert electrical energy into heat energy and light energy, solar energy can be converted to chemical energy, potential energy can be converted into kinetic energy, Gravitational potential energy can be converted into kinetic energy etc
Since the 2 strands of DNA are antiparallel to on another, DNA must be replicated both continuously and dis-continuously. The side of DNA that is replicated dis-continuously is done so in small parts called___________.
Answer:
Since the 2 strands of DNA are antiparallel to on another, DNA must be replicated both continuously and dis-continuously. The side of DNA that is replicated dis-continuously is done so in small parts called okazaki fragments.
Explanation:
OKAZAKI FRAGMENTS - Okazaki fragments are short DNA nucleotide sequences (roughly 150 to 200 base pairs in eukaryotes) that are synthesized in a non-linear fashion and then linked together by the enzyme DNA ligase to form the lagging strand during DNA replication. They shape short double-stranded DNA sections when combined with the lagging template strand.
The primosome initiates Okazaki fragments by generating a new RNA primer. To restart DNA synthesis, the DNA clamp loader releases the lagging strand from the sliding clamp and reattaches the clamp to the new RNA primer. DNA polymerase III will then synthesize the segment of DNA.
Reiji Okazaki, Tsuneko Okazaki, and their colleagues first found Okazaki fragments in 1968 while researching bacteriophage DNA replication in E. coli.

To manage the grizzly bear population better, the government of Alberta introduced a hunting lottery that awards a limited number of grizzly bear hunting licenses. Predict the year that this regulation was introduced.
Answer:
The correct answer is - 1990.
Explanation:
From the graph and year - population size table it is clearly understood that the population of grizzly bear is reduced by 39 number from year 1988 to 1989.
But after 1989 from 1990 onwards population of grizzly bear is consistently rising.
Now, let us analyse the data given in question number 2 .
No. of grizzly bear deaths in Alberta from 1976 to 1988 = 581
No. of grizzly bear deaths in Alberta from 1988 to 2000 = 281
From the above data we can clearly say now that the grizzly bear population deaths starts increasing from 1990.
So, the prediction made in question no. 1 that " the government of Alberta introduced the hunting lottery award in 1990 because in 1989 it decreases and then it starts to go up again in 1990",
Merchandise with a list price of $1500.00 is purchased on account for 900.00 on August 1. A.1500.00 B.900.00 C.600.00 D.882.00
Answer:
C. $600.00
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to find the difference between the list price and the purchased value by simply subtracting as shown below:
$1500.00 - $900.00
Which is equal to:
C. $600.00
