Answer:All living things are made of the same basic building blocks, cells. A human is made of 65 trillion cells. Cells are everywhere, on you skin, in your blood, and even on your tongue. In fact, your blood is clear but red blood cells are what make your blood red. Most living things are made up of many cells but some are made of only one cell, like amebas, paramecium, fungi, protists, monerans, and bacteria.
There are two basic types of cells, animal cells and plant cells. They have some common parts found in both and other parts that are unique to each. A cell membrane is found in both plant and animal cells. It is the structure that surrounds the cell and protects it. Plant cells have a cell wall, a rigid structure surrounding the cell membrane. Animal cells do not have a cell wall. Cytoplasm is the thick, jelly-like substance that makes up most of the cell. Vacuoles are fluid filled sacs in the cell. The vacuoles contain stored water or food that will be used by the cell. Cells also contain other "small organs" called organelles that carryout various cell functions. And then there is the control center of the cell, the nucleus, surrounded by a protective outer covering call the nuclear membrane. The nucleus contains the DNA, or chromosomes, that carries all the instructions on how a cell will function, live, and reproduce.
Every cell needs to energy to live and reproduce. Plant and animal cells obtain energy in different ways. Animals can not make their own food. They obtain energy by taking in food, water, and oxygen and converting it to sugar. Sugar is the only food a cell can eat. Plant cells can make their own food from water and sunlight. This process is called photosynthesis. Both plant and animal cells use energy from the food they obtain to reproduce.
All living things produce more living things. Cell reproduction is called mitosis.
Explanation:
You would have two splitting cells
Answer:
A. Falling raindrops are driven back up into the clouds by wind and freeze.
The initial assessment of bats suggested they lacked the ability to synthesize vitamin C (Birney, Jenness, and Ayaz 1976). However, several recent studies have shown that approximately two thirds of different bat species have functionally expressed GULO genes (Cui et al. 2011a; Cui et al. 2011b). The various bat taxon taxa that lack the ability to make vitamin C have varying levels of deletion degradation in their GULOgenes and the patterns of sequence variation show that they are lineage independent events. Trying to explain the discontinuous GULO deletion patterns within a common descent paradigm has produced a variety of difficult contradictions for a coherent model of bat<span> evolution </span>(Cui et al. 2011b).
Loss of vitamin C pathway function and GULO gene degradation has also been detected in guinea pigs, great apes, and humans (Lachapelle and Drouin 2011; Nishikimi, Kawai, and Yagi 1992; Nishikimi et al. 1994; Ohta and Nishikimi 1999). In addition, naturally occurring scurvy and osteogenic disease pathologies related to GULO inactivating mutations and large-scale deletions have been documented in rats, mice, and pigs (Harris et al. 2005; Hasan et al. 2004; Jiao et al. 2005; Kawai et al. 1992; Mohan et al. 2005). Thus, degradation of the GULO gene in a wide array of mammals and birds is a relatively common occurrence.
Answer:
The correct answer will be - in the bacterial cells
Explanation:
The complexity of life began on Earth when the simple amoeba-like organism started ingesting the bacterial cells. The ingestion of the aerobic respiration performing bacteria formed the mitochondria and ingestion of the photosynthetic bacteria formed the chloroplast of the cell. The bacteria while evolution lost their identity and now cannot live without the host cell.
This hypothesis was supported by the evidence like a comparison of the Ribosomes of this organelle is similar to the prokaryotic bacteria as the bacterial cell.
Thus, in the bacterial cells is the correct answer.
