<span>Within a more biodiverse ecosystem, there is a higher chance that species will be able to adapt to change. For example, even with the eradication or migration of any one particular food group, consumers higher up in the food chain will remain able to survive due to alternative sources of energy.</span>
Women are being advised to sleep on their side in the last three months of pregnancy, women in their third trimester are encouraged not to sleep on their backs. When they sleep on their back, the chances of the heavy uterus can reduce blood flow to the uterus and fetus, which can result in a stillbirth. Also, women are encouraged to sleep on their left side, as this is considered the best choice because the uterus naturally alternates to the right during pregnancy and left-sided lying will bring it more to the center and improve blood flow.
To help her sleep, a pillow can be placed between her legs or a long body pillow to support the back are often helpful. When a pillow is placed direct at her back and front, it helps support her body, resulting in a more comfortable position for sleep.
The major reason why she is having lightheadedness and dizziness when she lies on her back is that the weight of her uterus can compress a major blood vessel, called the vena cava, this then disrupts blood flow to the baby, leaving her nauseated, dizzy, and short of breath.

Typically you use experimental and control groups in an experiment. a control group is like the default, and the experimental is the one you actually experiment with.
for example if i run an experiment on the effects of food dye on a leaf stem, i’ll have my control group (the ones without food dye) to compare to the experimental group (the ones with food dye)
the control group is a way for scientists to see how an experiment truly affected or altered the subject
Answer:
Semi-conservation replication describes the mechanism of DNA replication in all known cells. This process is known as semi-conservation because two copies of the original DNA molecule are produced. Each copy contains one original strand and one newly-synthesized strand.
DNA is passed down to the next generation in big chunks called: Chromosomes.
Every generation, each parent passes half their chromosomes to their child. If nothing happened to the chromosomes between generations, then there would be around a 1 in 8 change that you would get no DNA from a great, great, great, great grandparent.
What most people forget, through, is that our chromosomes get mixed and matched before they are passed on. It is because of this "recombination" that your great, great, great grandparent's DNA is almost cetainly still lurking in yours.
