Answer:
Habitat Loss and Climate Crisis
Explanation:
Due to an increasing human population more and more area previously left untouched is being used to fulfill our demands. This leads to habitat loss for the bees and wasps.
Further, a change in climatic patterns might mean some species will find themselves at the right place in the wrong season.
A result of a disease that causes a thickened plasma membrane might be C. decreased movement of molecules entering the cell.
Cystic fibrosis is one of those diseases, and thus molecules cannot move when they enter a cell, thus a thickened membrane is created.
Meiosis produces cells (germ cells or gametes) with only half the DNA, or chromosomes, as normal cells (somatic cells). This is called haploid or referred to as "n" number of chromosomes. Normal body cells have doubke that, called "2n," or diploid. For humans our n = 23, so germ cells (haploid) have only 23 chromosomes, while somatic (normal body) cells have "2n" or 46 chromosomes. It is important to only carry half the number of chromosomes or DNA (n), because it is going to combine with another half (n) when sperm meets egg during fertilization. This n + n = 2n restores the diploid number of chromosomes (DNA) in a zygote, the first cell of a future embryo, fetus, and new human being.
There are 5 different levels of cellular organization.
Cells, tissues, organs, organ systems and whole organisms. Cells hold genetic material and absorb outside energy.
Tissues make up the bones, nerves and connective fibers of the body. Organs work to perform specific bodily tasks, such as filtering blood. Organ systems are groups of organs that perform a specific kind of function together, such as digesting food.
Together, these smaller systems make up an entire living organism which can grow and then go onto reproduce.
