Organs, cells with the same function make up tissue and tissue makes up the organ
Answer:
The researchers add a compound to the cell growth medium that both binds and releases protons (H+) and also pass through lipid membranes. The effect that the added compound will have on the ATP production by the cells is that ATP synthase will stop.
The little dots collected from under the fern leaves are spores, not seeds. Ferns are different from seed-bearing plants in that ferns in a sexless way through sporophyte generation. Spores dropped from or taken from grown fern leaves have developed prothallium. Each prothallium generates male and female organs in what is called the gametophyte stage. When fertilization of the female gametophyte happens, small fern plants or leaflets start to grow.
The best answer is C.
Enzymes are proteins that speed up the process of chemically breaking down food molecules. In other words they act as catalysyts. Catalaysts increase the rate at which chemical reactions occur without being consumed or permanently changed themselves.
A chemical reaction is a process that converts one or more substances known as substrates to another type of substance which is termed the product. As a catalyst, an enzyme can repeat the same type of reaction over and over again. Each enzyme has an active site where its specific substrate binds so that a reaction can begin to take place and continue to completion.
Answer:
Gl, gL, GL and gl
Explanation:
The heterozygous parent has the genotype Gl/gL. Since this is a diploid individual, it has two copies of each autosomal chromosome. The slash "/" represents a separation between the two homologous chromosomes, <em>Gl</em> are the alleles of genes "G" and "L" present in one chromosome, and <em>gL</em> are the alleles of those genes present in the other chromosome.
During meiosis the total chromosome number of the original diploid cell is reduced by half, creating four haploid gametes. In a specific stage of meiosis, homologous chromosomes pair and crossing over occurs, when recombination happens and one of the alleles present in one chromosome "switches" to the other chromosome, increasing genetic variation.
<u>Therefore, the Gl/gL individual can produce four different types of gametes:</u>
Gl and gL (Parental --> no crossing over occurred)
GL and gl (Recombinant --> crossing over occurred)
