Answer:
Yes
Explanation:
A phase change does not change the chemical make-up of a substance. Phase changes are typically temperature dependent, and change only the movement and physical arrangement of the atoms and molecules in the substance. Water, for example, is composed of two hydrogen atoms attached to an oxygen atom by covalent bonds. That stays the same whether the water is solid (ice), liquid (water), or gas (steam). The chemical structure of water does not change as it goes through the different faces. It's still water. What does change is the speed at which the molecules move and how far apart they are as a result. Water vapor consists of molecules moving quickly and at random. As temperature drops, water molecules slow down. Since water is slightly polar, hydrogen bonds form between the molecules bringing them closer together.
Answer: it stimulates the pancreas and the liver to produce secretions.
There are a lot of hormone in making a good digestion and is responsible in the process to function properly. Secretin stimulate bicarbonate (base) from the liver and pancreas to promote normal growth and maintenance of the pancreas. It also counteracts the blood glucose that triggers the increase of insulin release and oral glucose intake. It also reduce the gastric juice secreted by the stomach along the digestion.
Answer:
Do plants undergo photosynthesis, cellular respiration or both? plants undergoes both photosynthesis and cellular respiration
Explanation:
Plants are autotrophs i.e they produce food for themselves through a process called photosynthesis. Cellular respiration occurs both in plants and animals, it allows the conversion of adenosine diphosphate (ADP) into adenosine triphosphate (ATP). Plants needs energy which calls for it to undergo a chemical reaction called cellular respiration
Answer:
True
Explanation:
It is correct to say that the deeper in the ground we go, the older things get. This statement is specifically valid in a terrain that has not been disturbed by tectonic activities.
<em>According to the law of superposition of strata "in a sequence of sediment, the oldest layer is usually at the bottom and the youngest is on top provided the area is undisturbed". </em>
Based on this law of superposition of strata, it clearly seen that the deeper we go down in the earth, the older things get.
The expected progeny plants of the F2 generation (pink flower x<span> pink flower) will be:
</span>1/4 = 25% RR (homozygous dominant)- phenotype: red
2/4 = 50% Rr (heterozygous) phenotype: pink
1/4 = 25% rr (homozygous recessive)phenotype: white
R- red
r- white
