Answer:
<h2>RrYy and rryy
</h2>
Explanation:
1. As given; Round seeds (R) are dominant on wrinkled seeds (r),
Yellow seeds (Y) are dominant on green seeds (g).
In a testcross, between an unknown genotype and a homozygous recessive with wrinkled and green seeds (rryy).
offspring are:
Round and yellow are 53; genotype (R_Y_)
round and green are 49; genotype (R_yy)
wrinkle and yellow are 44; genotype (rrY_)
wrinkled and green are 51 ; genotype (rryy)
Here, the genotype of parents of these offspring would be RrYy and rryy.
That isn't even possible. Your body is made of them. If you had none then you wouldn't be existing.
The flooding of half part of the forest have successful separate the population of frogs in that ecosystem into two different set of frogs. This is an example of allopatric speciation, that is, the population become separated as a result of geographical barrier. This separation will make the two set of frog population to become new species. On the long run, the two species may become unable to relate sexually.
Answer:
D) The fungicide will reduce the stability of the ecosystem because nutrients in the soil will be less likely to be recycled, directly impacting plant nutrition and growth.
Explanation:
Fungicide are primarily applied to an area to kill off fungi species in that place.
Fungi are very important groups of organisms. They are natural "recyclers".
In a food chain or web they can be classified as decomposers.
Decomposers are organisms that takes feeds on dead and decaying organic matter.
The produce useful materials and releases nutrients from life back into nature.
Killing them off by applying fungicides is a damaging act to their sustenance.
Without decomposers such as fungi, the ecosystem becomes less stable and soil nutrients will not be properly recycled.
