Inside of plants, there are xylem cells that carry water and minerals from the roots, to the leaves, when the food then gets dispersed to the rest of the plant. This is similar to the human circulatory system but there isn't a heart pumping blood around. Hope this helps :)
Answer:
A,C E
Explanation:
The inner membrane of the mitochondria separate the matrix of the mitochondria from the cytosol(inner membrane space.). It is invaginated folded inwards to form the critae. This is an adaptive feature to increase the surface area for biochemical reaction in the mitochondria.
The invagination gives two compartments the inner mitochondria also creates the outer intermembrane space and the inner matrix
These are the substances that can pass freely the inner membrane of the mitochondria.Pyruvate and H+ can not pass through.Specifically,it is not preamble to H+ because, hydrogen ions are needed to generate the electrochemical gradients needed for the chemical energy for phosphorylation of ADP by P to form ATPs by the enzyme ATPase synthase.If the inner membrane is permeable to H+ the electochemical gradient will not be produced, and therefore ATPs productions stops.
O2 needs to pass through the inner membrane because it it the final electron acceptor. Therefore if not allowed to pass through oxidative phosphorylation and ETC will nor occur.
CO2 must pass through because its accumulation will increase the acidity of the inner mitochondria
The purple spots on the colorless background of corn kernels observed by Barbara McClintock were the result of the transposition of the Ds elements out of the color gene.
<h3>What are the genetic elements found in corn?</h3>
- A transposable element is removed from one spot in the DNA and inserted into a different site in the DNA during the process of genetic transposition, which allows genes to shift their location on chromosomes.
- The first recognized genetic instability was caused by genetic transposition.
- The size of the tissue patch displaying the reversion phenotype increases as a reversion event happens earlier in the kernel development.
- Barbara McClintock saw purple dots on maize kernels with an otherwise colorless background.
- These spots were caused by the Ds components of the color gene being transposed.
- The wild-type (purple) phenotype manifests itself in cells where Ds from the color gene "C" sequence has been lost.
Hence, Barbara McClintock discovered purple patches on the colorless backdrop of maize kernels due to the transposition of the Ds elements out of the color gene.

1 ) The first terrarium was developed by botanist Nathaniel Bagshaw Ward in 1842. He was interested in studying insect behaviour. Once he accidentally left one of his bug jars open. A fern spore in the jar sprouted, grew and germinated into a new plant. This is how the first terrarium had been created.
2 ) <span />Because of the different conditions within, terrariums there are two, which can be classified as closed and open. Closed terrariums have a lid to enclose the plants entirely within the glass container. Open terrariums do not require a lid.
Sorry working on this right now as well, and I don't have the others yet :(
