Answer:
The correct answer is "horizontal gene transfer".
Explanation:
The most common way at which genes are transferred is vertically, from parents to their descendants. However genes could be transferred among species, in what is known as horizontal gene transfer (HGT). HGT is most clearly seen in bacteria, actually HGT is the cause of the phenomenon of the development of antibiotic resistance. The theory of an ancient mitochondria moving their genes to the chromosomes of its host is most likely the result of HGT. This makes sense since an ancient mitochondria most likely behaved as an alpha proteobacteria, an ancient bacteria that already developed its HGT mechanism..
The correct answer is: a. the agar and air in the petri dish are providing all of the resources needed by the bacteria.
There are four phases of bacterial growth:
1. Lag phase-bacteria prepare for reproduction
2. Log phase- cell doubling
3. Stationary phase- due to a growth-limiting factor
4. Death phase.
D. Salamander is not a reptile.
It is an amphibian. It looks like a lizard but is not one. It lives on both land and water.
It's Kingdom Animalia; Phylum Chordata; Class Amphibia; Order Urodela with sub-orders Cryptobranchoidea, Salamandroidea, and Sirenoidea
Answer:
Facilitated diffusion
Explanation:
Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient.
Facilitated diffusion is a passive transport process because they only depend on electrochemical gradients, so they do not need any energy to occur.
