Oxytocin stimulates dilation of the cervix. As the cervical opening enlarges, this is an example of positive feedback.
Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.
Answer:
The body will behave as if it's being starved and the metabolic rates decreases.
Explanation:
Experimental Studies showed that individuals who used starvation diets for weight loss, consuming 50% of their body energy needs for three weeks, did have a significant reduction in their body weight entirely. It is also interesting to note that, if they lower their lean muscle mass by 5% it will reduce their lean muscle mass and organ size by 20%.
This leads to metabolism, resulting in a decrease in rate of metabolism causing a breakage of certain muscle stores so as to generate energy. Starvation diets is proven to give a far-reaching negative impacts on the body as starving to lose weight causes a decreases in the metabolic rate.
I found the exercise on the internet and bellow are the options:
"A. Seed cones contain ovules.
B. Germinated seeds are haploid.
C. A pollen tube is used to prevent the fertilization process.
<span>D. Pollen grains undergo meiosis to form egg cells."
The correct answer is D.
There are no seed cones, but pollen cones, where the ovules can be found. Germinated seeds are diploid, not haploid. The pollen tube role is to promote the fertilization process by leading the sperm to the egg, once the sperm in this type of plants do not have flagella and therefore no movement.
The correct answer is D because pollen grains are really the diploid germinative cells that </span><span>produce sperm cells.</span>
