Phospholipids are made up of fatty acids, glycerol, and phosphate.
If you're referring to the structure of a phospholipid, they are composed of a water-loving (hydrophilic) head and a water-fearing (hydrophobic) tail. The tail is made up of long chains of hydrogen and carbon molecules as well.
The answer would be D being those are all learned or earned attributes.
Answer:
Independent Variable: Hours of sleep
Dependent Variable: Test scores
Experimental Group: Group A
Control Group: Group B
Explanation:
Hours of sleep is the independant variable because it is the factor being tested by the teacher. This is the factor that can be controlled.
Test scores is the dependant variable because it is the factor being affected by the changes in the independent variable. This is the variable being measured.
Group A is the experimental group because this is the one that has been altered or changed from what is normal.
Group B is the control group because nothing is being changed in this group but simply measured as a basis for comparison.
Answer:
In both groups, sperm swim from antheridia to archegonia
Explanation:
Bryophytes are the plant group that does not have a vascular system. These plants do not produce seeds. Ferns and horsetails are seedless vascular plants. These plants have vascular tissues (xylem and phloem) to serve in the conduction of water, minerals, and sugars from the one plant part to the other. But these plants do not produce seeds and hence, are seedless vascular plants.
Both bryophytes and the seedless vascular plants depend on water for fertilization. These plants release their male gametes in water which in turn move towards the female gamete. Sperms, the male gametes of these plants swim in the water to reach the female gamete.
Antheridium is the male gametangium that serves as a site for the production of male gametes while archegonia are the female gametangia where the egg cell is produced.
