Club or other NGOs
O make environmentally conscious choices
O lobby the government for more money
Answer:
The answer is "make environmentally conscious choices"
Explanation:
All the human are the reasons for global environmental change through a subset of proximate causes, which straightforwardly modify parts of the climate in manners that have worldwide impacts. We start this section by laying out and showing a way to deal with representing the major proximate reasons for worldwide change, and afterward continue to the more troublesome issue of clarifying them.
Different contextual analyses delineate the different ways human activities can add to global environmental change and give solid foundation to the more hypothetical conversation that follows. We have recognized explicit exploration needs all through that conversation.

How much of the energy (what percentage) of oxidizing Glucose to Pyruvate is captured in Catabolism as NADH ( H ) and ATP?
Answer:
40 percent.
Explanation:
About 40 percent of energy as ATP is produced due to oxidizing Glucose molecule in the process of respiration while the remaining 60 percent is lost as heat energy which is responsible for the generation of high body temperature. One molecule of glucose produces four molecules of ATP, two molecules of NADH, and two molecules of pyruvate during the first stage of respiration known as glycolysis while in the end of respiration process only ATP, carbondioxide gas and water is produced.

The diagram shows the gases that enter and leave a plant during photosynthesis. Which
gases do arrows 1 and 2 represent?
*
(Photosynthesis)
(1 Point)
Arrow 1 represents nitrogen and arrow 2 is oxygen
Arrow 1 represents oxygen and arrow 2 is nitrogen
Arrow 1 represents oxygen and arrow 2 is carbon dioxide
Arrow 1 represents carbon dioxide and arrow 2 is oxygen
Answer: Arrow 1 is carbon dioxide, and arrow 2 is oxygen
Explanation: I got it right in a test.
Photosynthesis is the process of preparing food in the presence of sunlight, water, and carbon dioxide. The process is carried out by the plants and certain bacteria and algae.
The correct answer is:
Option D. Arrow 1 represents carbon dioxide and arrow 2 is oxygen
The mechanism of photosynthesis can be explained as:
Photosynthesis is the process in which light energy is converted into chemical energy. The plants use up carbon dioxide and water in the presence of sunlight to yield products. During photosynthesis, the plants yield oxygen as a by-product and produce a sugar molecule to be used as energy.
Thus, the plants use carbon dioxide and give out oxygen during photosynthesis.

An organism is exposed to a mutagen, such as X-rays or ultraviolet light. What could be the effect of the mutagen on the organism? Select all of the answers that apply.
The mutagen may disrupt gene function to the harm of the organism.
B. The mutagen may change gene function in a way that benefits the organism.
C. The mutagen may change the genetic material of the cell from DNA to proteins.
D. The mutagen may change the binding between codons and anticodons.
E. The mutagen may have little or no observable effect on the organism.
Answer:
a, b, c, e
Explanation:
- since mutations are random, they could both harm or benefit or have no effect on the organism (depends on where in the DNA is mutated, on the type of mutation that occurs, on whether the mutation is fixed, etc.)
- the binding between codons and anticodons are always as follows:
A on mRNA binds to U on tRNAT on mRNA binds to A on tRNAG on mRNA binds to C on tRNA and vice versaMutagens are substances that damage DNA and can cause permanent changes in the DNA sequence, depending on the ability of the organism to fix the mess.
Mutagen's effect:Deoxynucleoside triphosphates (dNTPs), which are utilized by DNA polymerases to duplicate DNA, can also be damaged by DNA-damaging agents.
A mutagen could harm the organism by disrupting gene function.A mutagen may alter gene function to the organism's benefit.A mutagen can alter codon-anticodon binding.Therefore, the final answer is "Option A, B, and D".

Which sequence describes the formation of a gamete?
A.transcription → replication → translation
B.replication → cell division I → cell division II
C.mitosis → cell division I → translation
D.cell division I → cell division II → transcription
Answer:
part c
Explanation:
The sequence replication → cell division I → cell division II describes the formation of gametes.
Where does the formation of gametes occur?Meiosis (reduced division), in which a germ cell splits into two pieces and produces four gametes, is the process by which gametes are created.
Meiosis is a type of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell.
The gonads are where gametes (germ cells) are made. This process is known as spermatogenesis in males and oogenesis in females. The majority of novel mutations arise during gametogenesis, however males exhibit a higher mutation rate.

Enter your answer in the provided box. Calculate the frequency of the genotype Aa from a population that is made up of the following numbers of individuals: 41 individuals with the genotype AA 23 individuals with the genotype Aa 28 individuals with the genotype aa frequency of individuals with genotype Aa g
Answer:
25% or 0.25
Explanation:
The frequency of the genotype Aa from the population can be calculated from the formula;
Frequency of Aa = number of individuals with Aa/total population
number of individuals with Aa genotype = 23
Total population = 41+23+28 = 92
Hence,
Frequency of Aa = 23/92 = 0.25 or 25%
