B asexually reproduction increases genetic diversity in a species.
C. asexually reproduction involves male and female organisms
D. asexually reproduction produces more organisms, but they all are genetically identical
Answer: D. asexually reproduction produces more organisms, but they all are genetically identical
Explanation: i took the test
Answer:
During meiosis 1, the parent cell with double the normal amount of chromosomes, splits into two diploid cells (have enough chromosomes to survive). During meiosis 2, the two diploid cells each split into two haploid cells (have half the amount of chromosomes to survive). Meiosis ends with four haploid cells.
Both Meiosis 1 and 2 have the same phases: Prophase, Metaphase, Anaphase and Telophase. One difference is that Meiosis 1 starts with a diploid cell and Meiosis 2 starts with 2 haploid cells, each with a homologous pair. ... Since there are no homologous pairs (only chromatids), recombination can not occur

Ice is one of the many products that can be derived from water. it is just only in solid or ice form, after going through a physical change.
When a pregnant woman is in labor, the body sends hormones that increase the intensity of contractions, which then increases the secretion of the same hormones.
When blood sugar is too low, the body sends hormones that raise blood sugar until it reaches a typical level and hormone secretion slows.
When a person is jogging, the body sends hormones that continually decrease the rate of oxygen supply to the legs
Answer:
The statement - When blood sugar is too low, the body sends hormones that raise blood sugar until it reaches a typical level and hormone secretion slows, describes a negative feedback loop.
Explanation:
In the human body, the term homeostasis means the tendency of the various systems in the human body to stay in optimal ranges for health by self regulation through feedback controls. It is very important because it maintains equilibrium and provides stability to the human body. A negative feedback loop (inhibitory loop) is a type of self-regulating system in which increased output from the system inhibits the future production by the system. Example of negative feedback to achieve homeostasis are blood pressure, body temperature, blood sugar. In blood sugar regulation, the hormone insulin lowers blood glucose when levels are high and the glucagon increases blood glucose when levels are low. In a positive feedback system, the output amplifies the original stimulus. Examples of a positive feedback system are child birth, lactation, blood clotting etc. During child birth, the hormone oxytocin released increases and speeds up the contractions.
