Answer:
E-You disagree because the resulting increase in phytoplankton at the surface would inhibit sunlight from penetrating into the water, thus inhibiting photosynthesis in the submerged plants.
Explanation:
Eutrophication is the process wherein nutrients specifically phosphorus and nitrogen are present in excess in a water body such as a lake. The increased concentration of nutrients promoter the growth of cyanobacteria and algae such as phytoplankton.
The increased population of phytoplankton in surface water reduces the oxygen availability and clarity of water for the organisms present in deeper layers. Also, reduced clarity of water limits the amount of solar radiations penetrating the surface water to reach the deeper layers.
Increased nutrient levels of the lake would rather inhibit the growth of submerged plants due to reduced availability of sunlight as caused by presence of phytoplankton in surface water.
It's Out Of C Or D Because It Explains It
Complete question: A phylogenetic tree shows that birds and crocodiles share many features. A hypothesis based on this tree predicts that these features are present in a common ancestor. Which of these predicted traits is supported by fossil evidence?
A) four-chambered heart
B) singing for territory
C) eggs and nests
D) singing to attract mates
Answer: (c) eggs and nests
Explanation:
A hypothesis based on phylogenetic tree shows that birds and crocodiles have ancestral connection. Fossil evidence shows that their common ancestor exhibit oviparity as a means of reproduction (i.e. laying of eggs and embryo develops within the egg), and also housed their eggs in the nest for protection against predators and other important reasons.
Answer:
Option c. Only the haploid organism may also reproduce asexually.
Explanation:
It is scientifically approved that algae and fungi are able to form true asexual spores. This process of spore formation involves mitosis and resultant spore is called mito-spore which develop into new offspring.
