A fetus develops in such a way that the type II cells of the lungs never develop, resulting in no production of surfactant in th
g100num [7]

Due to the high surface tension, the lungs remain crushed and you will not be able to breathe first.

During fertilization, the sperm and egg combine in one of the fallopian tubes to form a zygote. The zygote then descends the fallopian tube into a morula. Upon reaching the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the inner wall of the uterus. This is a process called implantation.

The prenatal development process occurs in three major stages. The first two weeks after conception are called the germination period, the third to eighth weeks are called the fetal period, and the period from the ninth week to birth is called the fetal period.

Thorns and small hairs on plant stems and leaves help to
Mkey [24]

The correct answer is - physically dettering herbivory, protection from frost, and minimizing evaporation.

The plants have developed multiple traits that help them in multiple different circumstances, and some of those traits are the thorns and the hairs on their steams and leaves.

The thorns primarily serve for protection of the plant. They are very sharp and give a painful sting (occasionally poisonous one), so they are a physical protection from the herbivores that would try to eat parts of the plants.

The hairs have multiple functions. They are like a coat that helps the plant to not be affected by frost, help to stop the evaporation, and also partially manage to stop most of the insects that feed on plants.
