How do Venus flytrap obtain <br> homeostasis
Minchanka [31]
- The Venus Flytrap survives in subtropical wetlands, it is the environment the venus flytrap needs, for example on the east coast of the USA, Brazil and Argentina. This means the venus flytrap wants lots of sunlight and humid conditions.
- It also lives in places where there is a low mineral level in the soil, so it gathers these vital nutrients from catching and digesting insects.
- For reproductive purposes, the flowers of Venus flytraps usually grows on tall stalks far above the leaves. This adaption of the plant is made so the the insects pollinating the flowers do not get trapped in the leaves. This is an anatomical adaptation that affects the flowers and the stems.

In pea plants, tallness (t) is dominant to shortness (t). what are the predicted percentages of the genotypes of the offspring i
Yuri [45]

If a homozygous short plant (tt) is crossed with a heterozygous tall plant (Tt), the percentage of tall offsprings is 50% and the percentage of short offspring is 50%.

  • A heterozygous tall pea plant will have the genotype "Tt" and a homozygous short pea plant will have the genotype "tt" because homozygous means that both alleles are identical.

  • Since 'T' is dominant over 't', any plant with at least one "T" allele will be tall (the dominant trait), regardless of what the other allele is.

  • The punett square of the following problem will have 2 squares with Tt genotype and 2 squares with tt genotype.

Hence, the genotypic ratio of F1 generation will be

Tt : tt

1 : 1

And phenotypic ratio of F1 generation will be

Tall : Short

1 : 1
