Students plan to conduct an experiment to measure the effect of light on photosynthesis in aquatic plants. The materials for this experiment are:30 g sodium bicarbonate (baking soda) Three 250 mL beakers filled with water Small aquatic plants, such as elodea Three large funnels with narrow tip Three large test tubes 100-watt lamp Procedure:1. Dissolve 10 ml of sodium bicarbonate into each beaker.2. With the help of an adult, cut the stem of each plant with a sharp razor blade 3. Place 5 plants under each funnel, then attach the test tubes to the top of each funnel. 4. Label the beaker setups as A, B, and C.- A is placed 10 cm. from the light source-B is placed 20 cm fram the light source-Is placed 30 cm from the light source 5. Set a timer for 10 minutes, then measure the displacement of the water of the top of the test tube This is the volume of oxygen produced 6. Conduct three trials of this experiment. Your experimental setup will look like this Part 3 Based on these results, predict what would happen if the test tube was placed 50 cm away from the light source. What would happen if the test tube was placed 1 cm away from the light source?

the answer to you question is   jet streams

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.

i think its white blood cells

i hope this

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )
