Answer: This is known as eco-localization and when they emit these waves they reflect them in fish; that way they know exactly where they are.
Answer:
Prophase of Mitotic phase
Explanation:
The cell cycle encompasses all the series of events that occurs in the cell from its DNA replication to the division of its cytoplasm (CYTOKINESIS). The cell cycle, however, consists of stages characterized by different changes; Interphase and Mitotic phase. The Interphase is the resting stage of the cell. It occurs between two successive divisions (mitosis). It consists of the G1, S, and G2 phases.
On the other hand, the Mitotic phase or M phase is where the actual division occurs. It consists of four stages viz: Prophase, Metaphase, Anaphase, Telophase. The Prophase is the stage that kicks off the division process called karyokinesis or mitosis. It is characterized by the condensation of the chromatin material into visible chromosomes. In this stage, the membrane that envelopes the nucleus (containing the chromosomes) is not yet degraded. The degradation of the nuclear envelope occurs in the metaphase stage, in order for the mitotic spindle to be able to attach to the kinetochore of each chromosome.
Answer:
3. B, D
Explanation:
A primary source is an animal that eats only plants. (herbivore) A secondary source is an animal that only eats herbivores (carnivores)
B has birds; which are food for carnivores, and fruits, nuts, and blossoms; which are food for herbivores.
D has vegetables and grains; which are food for herbivores, and meat; which is food for carnivores
The other options have only food for carnivores, or only food for herbivores, so the answer is 3
Answer:
The correct answer is C. Endosymbiotes
Explanation:
In endosymbiosis, one organism called endosymbiotes lives inside a larger organism in a symbiotic relationship with means both are benefitted from each other. According to the endosymbiotic theory, both chloroplast and mitochondria are generated through endosymbiosis of different bacteria by ancestral cells.
Therefore mitochondria is an evolved bacteria that was engulfed by a bigger bacteria. This is the reason why mitochondria contains its own genome and can replicate and divide but can not function outside the cell because it requires the condition present in the cell. So the right answer is C.
Genome is just the haploid set of the organism !
human has 46 chromosome ...So genome of human is 23 !
