Archea and Bacteria have prokaryotic cells, meaning their cells do not contain a membrane enclosed nucleus or other membrane enclosed organelles. The Eukarya ribosomal RNA (rRNA) sequence is unique and different from either the Archea or the Bacteria.
Sorry if this doesn't help :/
Flatworms have no need for circulatory and respiratory systems because they are able to actively diffuse oxygen through their skin and their body layout is such that they do not need to transport oxygen in order for it to get to their cells.
<span>Simple glucose through carbon fixation
Carbon dioxide enters the plants through its leaves. Present under the surface of leaves are small holes through which carbon dioxide diffuses into the plant to fulfil its requirements. The leaf also gives off oxygen from these same holes in the leaves. These small holes are called stomata which is the plural form. the singular form of this word, or a single hole on the underside of the leaf is called a stoma.</span> After it enters, the plant prepares the other needed requirements to perform photosynthesis such as water, sunlight and other nutrients.
He is right, it’s A. loss of Biodiversity.
Answer: The blank can be filled correctly by "if the seeds contain the gene or allele responsible for large size of the tomatoes"
Explanation:
In plants also, characters or traits of characters are defined by genes. Different alleles produce different traits of the same character.
For example, in classic Mendelian genetics, T was the allele responsible for tall plant trait while t was the responsible for dwarf trait.
Similarly, there would be a gene(s) responsible for size of the tomatoes. In addition, seeds are the products of sexual reproduction of plants. So, they may carry genetic combination different from parent plants (due to meiosis, crossing over, independent assortment, et cetera).
So, if the seed contains the gene or allele responsible for large size of tomatoes then only they will produce same kind of tomatoes.
