How does the transpiration mechanism compare with the coding mechanism of mammals?

1 answer:

3 0

<span>Trans = Transpiration is the process where plants absorb water through the roots and then give off water vapor through pores in their leaves. An example of transpiration is when a plant absorbs water in its roots. Persp = the process of sweating.</span>

Answer:

Implantation, gestation, and birth. Reproductive patterns in placental mammals are diverse, but in all cases a secretory phase is present in the uterine cycle, and the endometrium is maintained by secretions of progesterone from the corpus luteum.

What is the pH if 20 mL of pH = 2 solution is diluted to a final volume of 600 mL?

Mashutka [201]

Explanation:

Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge. pH measures how basic or acidic a water-based solutions are, with a formula for pH is

pH = -log[H+].

...where pH is -base 10 log of the concentration of hydrogen ions within the solution.

Initial volume= 20 mL

Final volume= 600 mL

# of dilutions= $\frac{600}{20}$ = 30

for a pH 2= [H+]= $10^{=2}$

∴ [H+]= $\frac{10^{-2}}{30} = 3.333 * 10^{-4}$

and pH is an antilog of [H+]= - log $\frac{10^{-2}}{30} = 3.333 * 10^{-4}$

∴pH = 3.47

The ability to curl one's tongue into a U-shape is a genetic trait. Curlers always have at least one curler parent but noncurler

irina1246 [14]

Answer:

A noncurler has a genotype cc.

Explanation:

If curlers always have at least one curler parent, it is possible being "curler" will be related to a dominant allele, in this example, "C". So, being "noncurler" could be a recessive trait. Noncurler can have one or both parents who are curlers, and this is concordant with a recessive inheritance if both parents are heterozygous (Cc) (with a probability of 25% of being "noncurler"). Also, it is possible if one parent is heterozygous and the other is homozygous for c (Cc x cc), this with a probability of 50% ob being "noncurler".

The Punnett square shows this clearly.

Receptors for acetylcholine are located on the

elena-s [515]

Answer:

plasma membrane of the target cell

Explanation:

There are two main types of acetylcholine (ACh)receptors:

muscarinic ACh receptors (because muscarin as agonist) which are G-protein coupled receptors that initiate slow response. Mostly, they are located in the central nervous system-CNS (involved in the release of neurotransmitters), heart (control of the heart rate), smooth muscles (contraction).
nicotinic ACh receptors (nicotin is agonist) which are ligand-gated ion channels involved in the fast response. They are located at neuromuscular junctions but also in CNS (involved in synaptic transmission between two neurons).
