Nonpolar fatty acid chains prevent organisms from dissolving in water.
Answer:
SARS-CoV-2 is the seventh coronavirus strain known to infect humans and it causes respiratory disease in humans. These viruses infect humans and are currently causing a pandemic in the world.
A pathogen is an infectious organism that causes illness or disease to its host. There are many types of pathogens that infect the body of the host that disrupts the normal physiological process of an organism. SARS CoV2 is also a pathogen as it infects the human body and disrupts its physiology and causes disease.
They are the managed consumption of natural resources to prevent their depletion or the destruction of the environment.
The house fly develops in four stages: egg, larva, pupal, and adult.
Explanation:
1. All of the following are periods of prenatal development except: a.germinal
b.embryonic
c.fetal
<u>d.postpartum</u>
Prenatal development describes the 40 week period before a child’s birth and the processes that occur during that time during prenatal development. Cells containing genetic material called chromosomes determine all physical characteristics of an organism including biological sex, height and eye color through expression of genes.
- The germinal stage describes the process from conception through implantation which is approximately two weeks, and begins when an egg is fertilized by sperm to form a zygote.
- The embryonic stage follows this until week eight of pregnancy; here the zygote divides into multiple cells in layers that determine systems like the nervous system; skeleton and respiratory system. The embryo travels through the fallopian tubes and implants itself in the lining of the uterus where blood vessels form the placenta.
- During the fetal stage spanning from week 9 until birth, differentiation, formation of sex organs internal organs and sensory perception occurs. The fetus also undergoes major brain development to form psychological and psychosocial traits. Immediately following the birth of the fetus is called the postnatal period
