Answer:

Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.

How can a gene map be used? Why do scientists induce mutations in organisms?
jarptica [38.1K]

Answer:

Genome mapping is used to identify and record the location of genes and the distances between genes on a chromosome. Genome mapping provided a critical starting point for the Human Genome Project. Sequenced DNA fragments can be aligned to the genome map to aid with the assembly of the genome.

By inducing mutations, scientists have been able to increase genetic variation, which breeders depend on to produce crops with desirable traits, such as resistance to diseases and insects. ... Mutations can be induced in a variety of ways, such as by exposure to ultraviolet or ionizing radiation or chemical mutagens.

As a child, Alex was short for his age. But during his teenage years, his height increased and he surpassed most of his friends.
Vladimir79 [104]

Answer:

B. Cells in Alex’s body underwent mitosis to create new tissue

Explanation:

Mitosis is the cell division that forms two genetically identical daughter cells from one parent cell. It occurs in somatic cells and is responsible for the growth and development of individuals.  

Alex gained the height as the cells in tissues of his body underwent the mitosis and produced new daughter cells. Repeated cycles of mitosis added a large number of new cells to his body to form new tissues in his body parts and caused an increase in his height.

Which molecules are used to produce glucose during the calvin cycle?
Lelechka [254]

Answer:

B. ATP & NADPH

Explanation:

fruits and vegetables are full of energy. Energy in the form of glucose. The energy from sunlight is briefly held in NADPH and ATP, which is needed to drive the formation of sugars such as glucose.

As Melvin Calvin discovered, carbon fixation is the first step of a cycle. The Calvin cycle transfers energy in small, controlled steps. Each step pushes molecules uphill in terms of energy content. Recall that in the electron transport chain, excited electrons lose energy to NADPH and ATP. In the Calvin cycle, NADPH and ATP formed in the light reactions lose their stored chemical energy to build glucose.
