Answer:
Natural selection
Explanation:
Natural populations have variations. Organisms of a population have various genetic traits. Some of these genetic variations make the organisms better suited to the prevailing environmental conditions. These organisms are more likely to produce more progeny. Over generations, the frequency of the beneficial genetic traits increases in the population due to the higher reproductive success of the organisms with these genetic traits.
This process of differential fitness of organisms of a population where the organisms with adaptive genetic traits have survival and reproductive benefits is called natural selection.
Answer: <u>The Plant Cell would die</u>
<u />
Explanation: Although the <u>Mitochondria</u> is unharmed the <u>Plant Cell</u> still needs the<u> Chloroplasts</u> because they are responsible for <u>Photosynthesis </u>which gives the plant energy, And without the Chloroplast ,Photosynthesis cannot be started
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
