Answer:
can you tell question in English your launguage I can't understand
Answer:
Specialized structures such as
1. The brightly colored flowers attract insects that transfer pollen from the anther to the stigma of another plant.
2. The scented smell of flowers and their nectars also attract insect and other pollinators to them.
Explanation:
Reproduction refers to the way by which plants and animals produce offspring or their types. Pollination, which is the transfer of pollen grains from the anther to the stigma of the same or another flower is a vital way by which plants accomplish this.
Structures of plants such as their brightly colored flowers, the nectars produced by them, as well as their characteristic smells attract pollinators to them that, in turn, aid reproduction.
Answer:
D) Frequency results from environmental stresses, not dominance.
Explanation:
The allele frequency refers to the amount of frequency of a particular allele in a small population whereas the dominance and recessive are the measure of the effects of the allele on the population which decides the trait of an organism.
The frequency and dominance cannot be correlated with each other as the frequency of the allele in a population is the result of the environmental stress which are random and by chances, whereas the effect of dominance is not random but is the result of the favoured trait for survival.
Thus, Option-D is correct.
Answer:
excretory system and circulatory system
Explanation:
Blood is part of circulatory system and as it move through various organs it exchanges the gases i.e give oxygen to the cell and take carbon dioxide from them. After taking CO2, the blood becomes impure and hence it passes through the kidney before going to the heart. Kidney is part of excretory system which removes carbon dioxide from blood and thus purifies it.
