Answer:
If wolfs were absent from their environment the food they eat like rabbits for example would be overabundant and eat all the plants and not leave any food left for other animals that need it and those animals would die.
Explanation:
Answer:
Be used as source of reserve cells for the entire blood production system.
Explanation:
Stem cells can be described as special human cells that are capable of developing into many different cell types ranging from brain cells to muscle cells. They act like renewable source of replacement cells for treating diseases.
In this case, the proliferative potential and self-renewal of stem cells makes them a compensatory mechanism and reserve source for the entire hematopoietic system. While they could be of possible use in certain autoimmune conditions or in cases of organ failure, these statements do not capture their essence.
It should be noted that, hematopoietic system is the system comprising the organs that are involved in the production of components of blood. And this is the major reason why the couple should engage in the act after consulting the caregiver.

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.
The human body comprises about 650 different muscles, and all are under the control of the nervous system. The nervous system comprises billions of neurons, which are in spontaneous contact with each other for the aim of regulating and monitoring the sensory and internal activities.
The actions like leaning over to pick a pen incorporate the coordinated attempt of various groups of muscles. The conscious mind transfers this signal to the central nervous system that further translates it into electrical impulses.
These are then further transferred to the somatic component of the peripheral nervous system to the nerves accountable for monitoring the required muscles. With the arrival of a message, a chemical known as acetylcholine gets discharged from the nerve endings, instigating the muscle fibers membrane and making them a contract.
