Answer:
<h2>Coevolution</h2>
Explanation:
Coevolution : It is the influence of closely associated species on each other in their evolution, they affect each other.
In coevolution , two or more species reciprocally affect evolution of each other by natural selection.
Coevolution Examples:
There are lots of examples of coevolution, some are here
i) coevolution of Predator-Prey , this relationship is one of the most common examples of coevolution.
ii) coevolution of Herbivores and plants,
iii) coevolution of Acacia ants and Acacias and
iii) coevolution of Flowering Plants and Pollinators and many others.
Complete question:
Prophase of meiosis I has some important differences from prophase of mitosis. These differences include: ___________BLANK pair, and _________BLANK occurs.
A: chromatids; condensation
B.,chromosomes; separation
C. homologous chromosomes; crossing over
D. homologous chromatids; separation
Answer:
C. homologous chromosomes; crossing over
Explanation:
Prophase I of meiosis and prophase of mitosis are quite distinct with respect to the events occurring in the cells. Prophase-I of meiosis is a relatively long stage. The Zygotene stage of prophase-I includes the pairing of homologous chromosomes. This pairing is mediated by synaptonemal complex and the process is called synapsis. The paired chromosomes undergo the process of crossing over during the pachytene stage of prophase-I. In crossing over, the non-sister chromatids of the bivalents exchange some genetic material between them. The events of synapsis and crossing over do not occur during prophase of mitosis.
Answer: During mitosis a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells.
Explanation:
Answer:
Pleiotropy
Explanation:
Marfan syndrome has several signs and symptoms depending on the individual affected.
The main manifestations of the disease are related to the skeletal system, in which the affected individual presents with elongated limbs, elevated height, scoliosis and thoracic deformations; the cardiac system, characterized by mitral valve prolapse (closing of the upper and lower chambers of the left side of the heart) and dilation of the aorta; and the ocular system, characterized by a detachment in the lens of the eye, and myopia.
The ability of genetic defects such as Marfan syndrome to reach such distinct organs is called pleiotropy.
Producers are organisms that make their own food. Plants would be an example. Primary consumers would be those that eat producers(plants,algae). Secondary consumers are animals that eat primary consumers. Herbivores are animals that only eat plants. Carnivores are those that only eat meat and don’t eat plants. Omnivores are those that eat both meat and plants. De composers are those that decompose organic material like dead animals. The herbivores here are the kangaroo rats,grasshoppers and bunny’s. The carnivores here are the hawk,lizard,tarantula and rattlesnake. I don’t think there is an omnivore. And the only decomposed here is the bacteria. As it decomposes the bodies of the animals when they are dead.
