Answer and Explanation:
These lights can, in fact, promote the growth and reproduction of plants.
This is because growth, chlorophyll production, flowering and fruiting only occur if the plant is exposed to a band of light with 640-720 nm. Plants receive this band of light naturally through the sun, but when solar energy is not available it is possible to use cultivation lamps that emit this type of light band, which corresponds to the yellow/red spectra.
<span>b. photosynthetic organisms provide energy for other organisms on earth.
B is the most suitable answer as photosynthetic organisms get their energy from the sun, and other organisms get their energy from photosynthetic organisms, so the sun is the source of energy for all life.</span>
Answer:
1. The DNA of every eukaryotic cell is stored in one or more CHROMOSOMES located in the NUCLEUS
2. Chromosomes contain most of the cell's DNA which acts as the molecule of heredity.
3. A duplicated chromosome remains tightly paired with its partner at a region called the CENTROMERE
.
4. Before a cell divides, it copies all of its chromosomes. While the two copies of a chromosome are attached they are called SISTER CHROMATIDS.
5. DNA and protein together form a complex called CHROMATIN.
Explanation:
Chromosomes are the structures present in the nucleus of the cells and become visible during stages of cell division. Chromosomes carry genes in linear order. Chromosomes are composed of thin threads of chromatin which in turn is made of DNA and its packing proteins. Condensation of chromatin during cell division makes the chromosomes visible.
DNA is a nucleic acid and serves to store genetic information. Stretch of DNA that codes for a specific protein is called a gene. Genes regulate the genetic traits of organisms.
DNA replication occurs during the S phase of the cell cycle. The replicated DNA is accommodated in sister chromatids of chromosomes. Before the S phase, each chromosome has one chromatid and after the S phase, each of the chromosomes has two sister chromatids that are held together at the centromere. Therefore, each of the two identical halves of a duplicated chromosome is called sister chromatid.
It adds more carbon into the atmosphere
This question is supposed to have a table showing species member tested and the type of cells tested and the results. Based on this table, the species member that would be unlikely to pass the gene mutation on to its offspring is species member 4: [Body cells (+) and Sperm (-)] Hope this helps.
