Plants make seeds that can grow into new plants, but if the seeds just fall to the ground under the parent plant, they might not get enough sun, water or nutrients from the soil. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire.

Blank 1: hawks and owls

Explanation: Tertiary consumers lie on the top of the food web or pyramid. They are dependent on other organisms for their food. These are carnivores by mode of nutrition. Here, the food web sequence would be like-

small birds----->snakes----->hawks and owls.

That's why they are the tertiary consumers.

Blank 2: decomposers

Explanation: The organic matter of dead plants and animals is decomposed by decomposers. They breakdown the complex organic compounds into simpler substances.

"Some people are tempted to say that the more genes an organism has, the more advanced it is. Discuss this idea: what kinds of a

stepan [7]

Answer:

The number of genes partially explains how an organism has evolved and how it gained complexity.

Explanation:

The number of genes of a bacteria versus an eucaryotic organism is quite distinct and so is their complexity. A prokaryotic organism like a bacteria has a set of genes necessary to exert their basic functions and the number of genes compared to a eucaryotic cell is 3-30 times smaller, which defines a direct correlation of number of genes and complexity. However if we consider only eucaryote organisms and their complexity there is no such direct correlation between number of genes and their complexity when, for example, we compare the number of genes of humans (approximately 18000) and the number of genes of the Trichomonas vaginalis, an anaerobic, flagellated protozoan parasite and the causative agent of trichomoniasis. The number of genes of T. vaginalis is far bigger than the human cell, however the human complexity is far more advanced than the parasite organism.

Glial cells called _____ help maintain the blood-brain barrier, whereas _____ create the myelin that envelopes axons. astrocytes

mihalych1998 [28]

Answer: Glial cells called ASTROCYTES help maintain the blood-brain barrier, whereas SCHWANN CELLS create the myelin that envelopes axons

Explanation: Glial cells are specialized cell that are found in both central and peripheral nervous systems, that surrounds the neurones, providing them with support and insulation. There are different types of Glial cells these includes:

- Astrocytes: they maintain the blood brain barrier.

- Schwann cells: create the myelin that envelopes axons of the peripheral nervous system neurones.

- satellite cells: These cells help regulate the external chemical environment of neurones.

- Microglia: they clean up cellular debris through phagocytosis.

- Oligodendrocytes: create the myelin that envelopes axons of the central nervous system
