Crossing over occurs at the four-strand stage when two homologous chromosomes, each consisting of a pair of sister chromatids, are paired. Each crossover involves just two of the four strands and generates two recombinant strands.
Hope this helps!
Answer:
A superbug refers to a germ that has formed resistance to multiple drugs that once treated the infection caused by the germ. The term “superbug” was developed by the media. While any germ may become a superbug, bacterial and fungal strains that routinely infect humans, animals, and crops are most likely to do so.
Superbugs are strains of bacteria that are resistant to several types of antibiotics. ... And the overuse and misuse of antibiotics helps to create drug-resistant bacteria. Here's how that might happen. When used properly, antibiotics can help destroy disease-causing bacteria.
The priority after administering is to assess fetal heart
rate. After administering an opioid to a laboring mother, the main concern is
to evaluate the effect on the fetus. Opioid administration can cross the
placental obstruction with signs as well as measuring heart rate and
variability. Subsequently after birth, there may be a reduction in attentiveness.
Maternal factors of a reduced blood pressure, constipation and dry month are of
a lesser importance.
Answer:
It could largely impact the way you look.
Explanation:
Since 100% of your DNA decides how you look, if even one thing changes, one part of your look would change. Sometimes it's something big like eye color, or sometimes like a small change in skin color.
<span>Enzymes are used up as a part of the reaction and cannot be used again. Enzymes can be any shape to bind to the substrate. Enzymes are catalysts that lower the activation energy allowing the reaction to occur. Enzymes are formed into lipids. 3. Which macromolecule is most likely to be broken down for quick energy? nucleic acid carbohydrate phospholipid protein
The Central Role of Enzymes as Biological Catalysts. A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.</span>
