Organs, cells with the same function make up tissue and tissue makes up the organ
The correct answer is - predator species in a community.
In the terrestrial ecosystems, a very good and usually sure predictor of the biodiversity is the existence of a predator species. The more predator species there are, the higher the biodiversity, and vice versa, the less predator species, the lesser the biodiversity.
The reason why the predators are such a good predictor of the biodiversity is that they are the species that are on the top of the food chain. That means that the predators are dependent for their survival on all the other species bellow them in the food chain, which is pretty much all species apart from themselves.
If a predator is present, than there has to be pray. If there's pray, omnivores and herbivores, than there has to be plants. All of the organisms are connected to one another, and the ones on the top of the food chain are the most dependent on the others, thus their existence usually means a healthy ecosystem with higher biodiversity.
Answer:
Whorl-1- petals
Whorl-2- petals (mutant)
Whorl-3- carpels (mutant)
Whorl-4- carpels
Explanation:
ABC model of flower explains the role of various genes in the formation of a flower from the shoot. Each gene forms a particular structure of a flower in the following manner:
1. A gene -sepals. (Whorl-1)
2. A + B- Petals (Whorl-2)
3. B+ C - stamens (Whorl-3)
4. C- carpels. (Whorl-4)
If a flower lacks the B gene, the effect will be observed in the phenotype in which B gene is involved that is in the formation of petals and stamens or whorl 2 and whorl 3.
The flower will produce
whorl-1- petals
Whorl-2- petals (mutant)
Whorl-3- carpels (mutant)
Whorl-4- carpels
Answer:
b. Foraging birds eat left over rice and trample the ground making trilling unnecessary.
Explanation:
The California ricelands Habitat Partnership is a partnership between rice farmer and conservation group that will promote long term sustainability of wetland species.
This farming method is beneficial to both the farmers and the species. The wetland species such as foraging birds will benefit by coming to eat the left over rice after the farmers have harvested the rice.
As the birds eat the rice, they trample the grounds making trilling unnecessary hence benefiting the rice farmers.
