Phase 3
Explanation:
Phase 3 of the systems development life cycle describes the desired features and operations of the system. The objective of the systems design phase is to transform all requirements into detailed specifications covering all aspects of the system. It should also assess and plan for security risks. Finally, approval to progress to the development phase must be granted to complete the systems design phase.
what experiments led to the discovery of dna as the hereditary material?
Answers
Answer:
In the 1920s, Frederick Griffith He was studying two different strains of a bacterium, called R (rough) strain and S (smooth) strain. He injected the two strains into mice. The S strain killed (virulent) the mice, but the R strain did not (non-virulent). Griffith also injected mice with S-strain bacteria that had been killed by heat. As expected, the killed bacteria did not harm the mice. However, when the dead S-strain bacteria were mixed with live R-strain bacteria and injected, the mice died.

What is the most likely explanation of the data shown below?
A 3 column table with 6 rows. Column 1 is labeled Year with entries 0, 1, 2, 3, 4, 5. Column 2 is labeled Dark moths with entries 50 percent, 59 percent, 68 percent, 80 percent, 95 percent, 100 percent. Column 3 is labeled Light moths with entries 50 percent 41 percent, 32 percent, 20 percent, 5 percent, 0 percent.
a.
There has been a drought in the area that is affecting all life forms.
b.
The population of natural predators of the moths has gotten smaller.
c.
The moths are living in an environment with light trees.
d.
The moths are living in an environment with dark trees.
Answers
Answer:
The correct answer is D. The moths are living in an environment with dark trees.
Explanation:
In general, the data shows the population of light moths increases over time, while the population of light moths decreases to the point it disappeared. This would likely occur if there was an environmental change that allowed dark moths to have survival and reproductive advantage over light moths. This includes if the trees are dark because in this scenario dark moths have a better chance to avoid predators and reproduce, while light moths would have a lower chance to survive because predators can find them easily and this leads to the decrease in light moths population shown in the chart.

Answer: As the change in allele frequency causes the change in genome of the living organism inside few generations.
Explanation: The effect may leave the organism with the loss of some genes, while it can effect cause the loss of some of the beneficial genes inside the genome of the organism. Along with that the process can also improve the sequence of genes which are abnormal in nature.
What is unique about active sites?
A: active sites provide cells with energy.
B: active sites are specific to certain substrates (reactants).
C: active sites store the genetic information of cells.
Answers
The Unique feature of Active sites is that active sites are specific to certain substrates (reactants)
Active sites are specific regions of an enzyme where substrate molecules bind in other to bring about a chemical reaction.
The active site is made up of amino acid which forms temporary bonds with the substrate otherwise known as the binding site and the residues which brings about a reaction of that substrate.
Active sites are specific to certain substrates (reactants). Therefore, option (B) is correct.
Active sites are vital to enzymes, proteins that aid biological processes. They have a distinctive form that matches their substrate molecules. This specificity allows only particular substrates to bind to and interact with the active site, catalysing processes. This is called the "lock and key" or "induced fit" model.
Enzymes' catalytic action depends on active sites. A substrate attaches to an enzyme's active site and changes conformation, lowering the reaction's activation energy. This speeds up the reaction. After the reaction, the products are released and the enzyme's active site can bind to another substrate. Therefore, option (B) is correct.

Why might cyanide-producing clover produce striped leaves?
Answers
Answer:
increases its ability to resist predation because the snails that eat it die
In general, two types of white clover can be found in a variety of habitats around the world. The first has plain green leaves, while the second produces cyanide as a defensive strategy against herbivores and signals its presence with white stripes on the leaves.
What are defensive behavior?Claws, teeth, disguising, poison, imitation, and adaptations such as echolocation are all common defense mechanisms. Some are uncommon but extremely effective.
A nonhuman animal's behavior to avoid of been hurt or killed by another.
This could include defensive aggression against a potential predator or a member of its own species, from its own group or from another group, or animal escape actions to avoid the source of harm.
In general, two types of white clover can be encountered in a variety of habitats worldwide.

Nature vs. Nurture both influence the observed traits of an organism.
The controversy between nature and nurture have been an ongoing discourse for many years. It is believed that the traits of an organism are dependent on genes inherited from the parents. Another school of thought believes that environment alone has the sole influence over the traits of an organism.
However, most scientists today are of the opinion that the influence of nature and nurture are intertwined and they both work together to influence the traits exhibited by any organism.
