At the time of Mendel’s pea plant experiments, no one knew how organisms formed gametes. As Mendel studied the inheritance of tw

o different characters, he wondered how the alleles for the two characters segregated into gametes. Mendel had two hypotheses for how this might work.

Answer:

Explanation:

one of the hypothesis put forward by Gregor Mendel states that when two different alleles are inherited together, one may be expressed, while the effect of the other may be masked.

the second hypothesis states that when gametes are formed, the two alleles of each gene are segregated.

Zolol [24]

Answer:

A. We can deduce that microorganisms such as Citrobacter have a classification from which it is possible to establish the most favorable environment for it, since being gram-negative, lactose positive, optional anaerobic, not endospore, it will prefer the environment as humid sites and that contain wastewater and soil as well as the intestine, it can therefore remain in some contaminated food and be transmitted with consumption

B. Given the aforementioned characteristics of Citrobacter, it does not infect all people and prefers those who have deficits in its defense mechanisms, thus it becomes a favorable site for colonization of newborns, who do not have adequate immunity, according to the case. Clinically, the neonate was able to acquire the infection in various ways, although the medical personnel who have manipulated it do not have positive tests, the microorganism can adhere to contaminated surfaces and it will be necessary to take samples of the mother's and neonate's feces, as well as the soil. and the water where the infected was, to subsequently carry out disinfection processes in the areas and avoid new infections.

In fast-twitch oxidative-glycolytic fibers, their rapid increases in force rely on the ________ activity where rapid relaxation
Kitty [74]

Answer:

1. myosin ATPase

2. Ca2+-ATPase

Explanation:

ATPase activity of myosin head hydrolysis ATP and energize the myosin head. The energized myosin head forms cross bridges to facilitate the power stroke of muscle contraction. The fast-twitch oxidative-glycolytic fibers have the ability to produce ATP by aerobic respiration.  

These fibers have the  ATPase in their myosin heads that hydrolyze ATP three to five times faster than the myosin ATPase in slow fibers. This ensures the faster speed of contraction of these fast-twitch muscle fibers.

During their relaxation, Ca2+ ATPase pumps the calcium ions back to the sarcoplasmic reticulum. As the level of Ca2+ ions in the sarcoplasm decreases, calcium ions are released from troponin. Tropomyosin is allowed to cover the myosin-binding sites on actin and the muscle fiber relaxes faster.

In about 100 words, explain how the use of flashback adds meaning to “Rules of the Game.” Be sure to use details from the story
babymother [125]

Answer:

The use of flashback in "Rules of the Game" provides insight into the complicated relationship between Waverly and her mother. Throughout the story, Waverly describes past incidents when cultural differences caused her and her mother to view events differently. Waverly sees events differently because of her American upbringing. Her mother sees events differently because of her Chinese upbringing. Waverly notes that her mother has had difficulty adjusting to American culture. She shows this struggle when she describes her mother’s reaction to the game manual for her brother’s new chess set:

“This American rules,” she concluded at last. “Every time people come out from foreign country, must know rules. You not know, judge say, Too bad, go back. They not telling you why so you can use their way go forward. They say, Don’t know why, you find out yourself. But they knowing all the time. Better you take it, find out why yourself.” She tossed her head back with a satisfied smile.
