Answer:
The correct answer is (1) digestive and circulatory
Explanation:
Digestive system helps in digestion of complex organic matter present in the food like polysaccharides, proteins, lipids, etc. So due to the function of the digestive system, these complex molecules are converted into simpler forms like glucose, amino acids, etc. Then these simpler forms are absorbed in the body through intestine.
Ribosomes help in the production of proteins which requires amino- acids so the absorbed amino acids are moved into the cells through the circulatory system. Therefore digestive system and circulatory system provide the molecules required for metabolic activities.
The right option is; dark-field microscope
A light microscope that makes the specimen appear light on a dark background is called a dark field microscope.
Dark field microscopes are light microscopes that are used in different ways to clearly view various specimens that are unstained, transparent, and hard to see using a light field unit. Dark field microscopes are very effective because they show the details of unstained and live samples. It is also very simple to use, and inexpensive to set up.
Answer:
The parents must be Tt, Tt
Explanation:
Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:
T t
T TT Tt
t Tt tt
We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).
This means that the parents must be Tt, Tt.
I would say it’s probably B or C
