The hydrogen ion concentration of a solution is indicated by its <u>pH </u>value.

Explanation:

  • A measure of acidity or alkalinity of water soluble substances (pH stands for 'potential of Hydrogen'). A pH value is a number from 1 to 14, with 7 as the middle point.
  • Under normal circumstances this means that the concentration of hydrogen ions in acidic solution can be taken to be equal to the concentration of the acid.
  • The pH is then equal to minus the logarithm of the concentration value.
  • Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.
  • The pH of a solution is a measure of hydrogen ion concentration, which in turn is a measure of its acidity.
  • Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions. For a neutral solution, [H+] is 10−7, or pH = 7.

Cerrena [4.2K]

Procreation comes from pairing. In different phrases you have 2 codes for each little thing. you have the code from the father and the code from the mother. evaluate the code for blood. you're attentive to that there are 4 varieties of blood variety O, variety A and variety B and variety AB. If mom has 2 codes for her blood, enable us to declare O and O and father has 2 codes for his blood enable us to declare O and A There are a sequence variety of combinatins the 1st mom O can combine with father O, OO The 2d mom O can combine with father A, OA. the 1st mom O can combine with father A, OA The 2d mom O can combine with father O, OO the baby is going to have the two OO or OA. If the baby has OO the the baby has no selection different than to have blood variety O because of fact the expressed phenotype. If the baby has OA the A is dominate and it takes expression. subsequently the only way a recessive allele could be expressed is that if and on condition that there are 2 recessive allele as interior the case of OO. Now do the different combinations mom OO mom OA mom AA mom OB mom BB mom OO can combine with father OO making OO mom OO can combine with father OA making OA mom OO can combine with father AA making OA mom OO can combine with father OB making OB mom OO can combine with father BB making BB The recessive allele is expressed if and on condition that the two codes are recessive. What if mom is dominant A. mom AA mom OA can a recessive allele be produced particular If and on condition that the recessive O of the mother combines with a recessive O of the father. subsequently a mom dominant A might desire to be coded as OA and a father dominant A might desire to be coded as OA. the baby can get carry of mom O blended with the father O and be OO, the recessive. the baby is recessive even whilst the mothers and dads are dominant because of fact the mothers and dads carried the recessive allele. this might ensue if and on condition that the two mothers and dads carry the recessive allele. pass via the mixture mom OA Father AA you will by no capacity get a recessive phenotype expressed

Step 11 of skeletal muscle contraction:__________.
malfutka [58]

Answer:

The suitable option will be - B

B) Phosphate and ADP form to make ATP which binds to the myosin head and causes cross-bridge to detach.

Explanation:

Until step 11, skeletal muscle has already done cross-bridge and power stroke. ADP is released just after the power stroke. After that phosphate and ADP form a new ATP which gets bound to the myosin head.  

Then at step 11, cross-bridge is released as a new ATP is bound to myosin head.  

So, we can say that option B is correct.

grigory [225]

Answer:

Apple tree and grass are producers, mushroom and bacteria are decomposers, and everything else are consumers. The bear is herbivore I believe, the rabbit is as well to my understanding. The pig is omnivore and lion is carnivore.

Explanation:

Starting with producers, most plants are producers. They photosynthesize to make their own food (glucose). Decomposers break things down like dead animals. Carnivores eat only meat, which is what a lion does. It eats no plants. The pig is an omnivore, meaning that it eats both meat AND plants. Lastly, the bear and rabbit are herbivores meaning that they only eat plants. I always remember it as "HERBivore which sounds like HERBS which are plants" Hope this helps!

In what places have bacteria resistant to antibiotics caused particular problems?
GenaCL600 [577]

Answer:

Bacteria that are non-controlled or destroyed by antibiotics are antibiotic-resistant bacteria. In the presence of an antibiotic, they will live and even develop. At least certain antibiotics can become immune to most infection-causing bacteria.

Explanation:

Some bacteria are immune to such antibiotics naturally. In most species found within the human digestive system, for example, benzylpenicillin has very little impact.
