In this activity, you’ll open your non-dominant hand (the hand that you don’t use for writing) and then squeeze it into a tight fist as quickly as you can for 100 seconds and write down the number of squeezes every 10 seconds. If you have access to a ball, you can squeeze the ball with your non-dominant hand instead. How do you think the number of squeezes you can perform will change over the course of the experiment? How many squeezes do you think you can perform during the last 10 seconds of the experiment?

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
