<u>Answer:</u>
<em>Caurepa taxifolia is an invasive species of algae and is listed in the IUCN list of 100 invasive species.
</em>
<u>Explanation:</u>
In is an algae usually found in the pacific ocean. It was earlier used in aquariums as an <em>ornamental species of algae</em>. The dangerously invasive nature overshadows its attractive appearance.
It is inedible and increases in numbers at a surprisingly <em>accelerated rate.</em> The growth of other plants is difficult in areas dominated by the Caurepa taxifolia. The introduction of this <em>algae was in the Meditteranian sea.
</em>
The correct answer is: B. In sexual reproduction, individuals transmit half of their nuclear genes to each of their offspring.
The main difference between sexual and asexual reproduction is that in sexual reproduction genetic material from two parents is combined, while in asexual reproduction produced offspring is genetically identical to the one parent. So, advantage of sexual reproduction is that produced unique organisms contribute to genetic diversity (variation is formed). But, comparing to asexual reproduction, sexual reproduction requires more energy and lasts longer.
Asexual reproduction is found in lower organisms and can be in different forms: budding, vegetative reproduction, fragmentation, spore formation.
Answer:
They are building blocks for larger polysaccharide which are important in structural rigidity of cells.
Polysaccharides such as Starch and Cellulose which are instrumental in cell structure and rigidity are formed from chains of monosaccharides.
They are also useful in the provision of energy which is used in cell functions (metabolism).
Monosaccharides such as Glucose, Sucrose are useful in provision of energy for physical and metabolic activities of the body.
<u>Answer:</u>
Limited resources contribute to evolutionary change in animals by increasing Intra-specific competition.
<u>Explanation:</u>
- Intra-specific competition means competition among the members of same species.
- Individual of same species have same ecological niche i.e. how an organism is related with biotic and abiotic aspect of environment.
- So they require same resources of their survival. When population of any species increases then there is high chance of intra-specific competition because of limited resources.
- Intra-specific competition also determine the population size of species. For example, competition among shark rodents.
