Is the phosphate group attracted to water (hydrophilic) or is it repelled by water (hydrophobic)

1 answer:

6 0

Answer: The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic. Since the heads are hydrophilic, they face outward and are attracted to the intracellular and extracellular fluid.

Answer:C) Traits like this are determined by the genes passed from parents to their children.

Explanation: Every trait in an organism is controlled by a pair of gene. A gene that controls a trait usually have two alleles. During fertilization, for every pair of gene one allele is inherited from the mother while the other allele is inherited from the father and the two alleles come together to form a pair of gene. Every trait in an organism is determined by genes that are passed from the parents to the offsprings.

The city of Los Angeles wants to know if there is a connection between physical fitness and air pollution. Fifty volunteers from

zheka24 [161]

Answer:

Control group: volunteer stationary bike riders in a pollution-free chamber

Experimental group: volunteer stationary bike riders in a chamber filled with air pollutants common to Los Angeles

Independent variable: exposure to air pollution

Dependent variable: The heart rates (physical fitness) of the volunteer riders.

Explanation:

In a scientific experiment, data is compared between the control group and experimental group to ascertain the effect of the independent variable on the dependent variable. A control group is the group in an experiment that is not treated with the independent variable i.e. the independent variable is controlled while the experimental group is the group that is treated with an independent variable.

N.B: The independent variable is the variable controlled by the experimenter in order to influence the dependent variable (measurable outcome).

In this experiment, the independent variable is the AIR POLLUTION the volunteer riders are exposed to while the dependent variable is the PHYSICAL FITNESS/ HEART RATES of the volunteer riders, which is dependent on the exposure to air pollution (independent variable).

The control group in this experiment is the volunteer riders placed in a POLLUTION-FREE CHAMBER where the independent variable cannot influence or have any effect on the measurable variable (dependent). The experimental group is the volunteer riders placed in a CHAMBER FILLED WITH AIR POLLUTANTS. The independent variable (air pollution) has been changed in the experimental group.
