Answer:
The correct answer is option a. "lower melting temperature".
Explanation:
Food makers add hydrogen to vegetable oil in order to make them more solid. The melting point of vegetable oils that go trough a partial hydrogenation process do not lower, actually, the melting point increases. Vegetable oils that are partially hydrogenated are partially saturated, which in consequence increases its melting point to the point that they could be solid at room temperature.
Ans. (C). lipids.
Oleic acid, phospholipids, and brassinosteroid hormone are examples of lipid molecules. Lipids are non-polar, water insoluble organic compounds, which include triglycerides, phospholipids, steroids, and natural oils.
Oleic acid is an example of fatty acid that helps in insulating the body and energy storage. Phospholipids are fatty acid derivatives, which represent major components of cell membranes. Brassinosteroid is a steroid hormone, which acts as a signalling molecule in plants.
Thus, the correct answer is option (C).
The answer would be: C) sexual selection.
Sexual selection happens where one of the individuals choose the partner to sex based on some criteria. In this case, the ability to have a beautiful bower will determinate the ability of the bird to have sex and produce offspring. The criteria are not limited to visual. It could be diverse in other cases, like a deeper croak in frog
Tertiary consumers produces less biomass but result in higher biomagnification.
<h3>What are different types of consumers?</h3>
Compared to primary consumers, tertiary consumers spend less energy. Organisms that eat secondary consumers are considered as tertiary consumers. Primary consumers are herbivores that devour plants. Consider insects. Secondary consumers are small carnivores that eat other animals, often herbivores. Consider frogs. Tertiary consumers are large carnivores that eat other animals, particularly secondary consumers. Consider birds. Bugs, frogs, and birds(First-tier consumers) The secondary market (Tertiary consumers).
The higher an animal is on the food chain (such as third-party consumers like seals), the higher the concentration of DDT in their bodies as a result of a process called biomagnification.
