Hello,
Your answer would be:
D. stalactite; stalagmite
Plz mark me brainliest
Answer is A Sunlight because the grass are staying in the shade which they’re not getting sun light
Answer:
C. Fi 1:0, F2 3:1
Explanation:
Firstly, Mendel's law of segregation states that the alleles of a gene will randomly separate into gametes during gamete formation. In this case involving a single trait, hence, a single gene. Mendel crossed two purebreeding plants i.e. homozygous plants that produced different phenotypes for the same gene. He obtained his offsprings which he called F1 offsprings. He realized that all the F1 offsprings expressed only one phenotype. For example, when he crossed homozygous tall (TT) and short (tt) plants, he got F1 offsprings that were all tall.
He then self-crossed these F1 offsprings to produce a F2 offsprings that had a phenotypic ratio of 3:1 i.e. 3tall, 1short plant. He concluded that the alleles of the single gene had segregated into the gametes but one allele was capable of masking the expression of another, as seen in the heterozygous F1 offsprings that were all tall (Tt).
Hence, he obtained a 1:O ratio for his F1 offsprings then a 3:1 ratio for his F2 offsprings.
Potato tuber cells do not contain chloroplasts as they are grown inside the soil so no sunlight is required so no chloroplasts.
Explanation:
Instead of chloroplasts potato tubers consists of amyloplasts. In all plant cells, plastids are always there. They are required as it is the place where amino acids and fatty acids are made. Amyloplasts are the place of starch synthesis in non-green plants.
If you place the potato tuber in sunlight the amyloplast may get converted to chloroplasts.
A hand-held SPAD-502 plus chlorophyll meter device is to check the chloroplasts.
They all apply except for D
