A rainforest plant would be least affected by the loss of guard cell function that closes the stomata.
<h3>What is Guard Cells?</h3>
Guard cells are types of specialized plant cells present in the epidermis of leaves, stems, and other organs that are used to control gas exchange.
They are produced in pairs with a gap between them that forms the stomatal pore. They are kidney-shaped cells that surround stomata and control the opening and closing of stomata.
When there is an excess of water in the plant, the guard cells swell and form a hole for the exchange of gases.
Thus, a rainforest plant would be least affected by the loss of guard cell function that closes the stomata.

the answer to this problem is c
The answer is C) 3/4
Let's analyze separately each of the traits:
Parental generation: AA x Aa
F1 generation: AA AA Aa Aa
So, all progeny will <span>phenotypically resemble the first parent.
</span>Parental generation: BB x bb
F1 generation: Bb Bb Bb Bb
So, all progeny will <span>phenotypically resemble the first parent.
</span>
Parental generation: Cc x Cc
<span>F1 generation: CC Cc Cc cc
</span>Only 3 (CC, Cc, Cc) out of 4 progeny will <span>phenotypically resemble the first parent.
The genotypes for first two traits will not affect </span>phenotypical resemblance to the first parent. So, it only counts the third trait, for which the chance to have progeny that <span>phenotypically resemble the first parent is 3/4.</span>
The methicillin-resistant form of the bacterium commonly known as staph was first identified in the 1970's in hospitals, but it has since spread across the world, showing up in day cares, schools and other public spaces. Today, 1.2 million MRSA infections occur in hospitals in the U.S. and invasive MRSA kills over 19,000 per year,However, In the past, penicillin was used to treat Staphylococcus aureus infections. Shortly after, S. aureus became resistant to penicillin. During the 1950s, derivatives of penicillin was discovered by pharmaceutical companies that could treat Staphylococcus aureus . The graph below depicts the Spread of Antibiotic-Resistant S. aureus Infections in the United States. Separate curves are shown for bacteria that caused infections in the hospital ("Hospital-Acquired") and in healthy people in the community ("Community-Acquired").

<span>1) It is the chromosomes, however, that assort independently, not individual genes.
2) </span> <span>It tells you they're really far apart.
You see, there's this phenomenon called crossing over. Chunks of DNA get randomly swapped between homologous chromosomes. If two genes are close together they're usually swapped together and if they're far apart (say, on opposite ends) they're probably never going to be swapped together because half a chromosome doesn't normally cross over at once.
</span>
3) <span>Sexual reproduction, because it results in offspring that combine alleles from two different individuals. </span>
<span>(Crossover is fine and dandy and you should mention it, but you'd get a C if you didn't mention that two different individuals are contributing genetic material to the offspring)</span>
