Machines known as “DNA synthesizers” can produce short pieces of DNA.
True or false
Answer:
Machines known as DNA synthesizers are used to produce short pieces of DNA, up to several hundred bases in length. These synthetic sequences can then be joined to natural sequences using DNA ligase or other enzymes that splice DNA together. A gene from one organism can be attached to the DNA of another organism.

is a grasshopper a herbivore carnivore or omnivore
Grasshoppers are well-known plant-eating insects that are herbivores.
Their typical diet consists of a variety of plant material such as grasses, leaves and plant stems. They chew and eat plant matter using their powerful jaws. Grasshoppers' digestive tracts contain symbiotic microbes that help them digest cellulose, a complex carbohydrate found in plants.
Although the primary trait of grasshoppers is herbivory, it is important to note that under certain circumstances, particularly when resources are limited, some species may engage in cannibalism. However, they are clearly classified as herbivores because of their overall diet and ecological function in the ecosystem.

In living organisms the cell
cycle is closely regulated.
What do you think will
happen if cell division is not
controlled?
Answer:
Explanation:
Disruption of normal regulation of the cell cycle can lead to diseases such as cancer. When the cell cycle proceeds without control, cells can divide without order and accumulate genetic errors that can lead to a cancerous tumor
The cell life cycle is controlled meaning that:
The reproduction of the cell is controlled.
The cell has a "programated death" meaning that at some point, all normal cells die.
If there is a problem with these (uncontrolled reproduction or cells that just not die) a tumor will appear.
Where the tumor is just a mass of these cells that reproduce uncontrolled and that don't die naturally.
So the thing that happens if cell division is not controlled, is that a tumor will appear.

what is the most durable part of the human body?
Answer:
the most durable and tough substance in your body is actually a tissue. Encasing your teeth and helping you chew, bite, and tear your food is your tooth enamel. That's the hardest substance in the human body.
Explanation:
The most durable part of the human body is Tooth Enamel.
What is Tooth Enamel?Tooth enamel is defined as the thin outer covering of the tooth that covers the crown of the tooth. This is the part that we can see outside the gums. This is the outer layer, the enamel is transparent. Dentin is the hard tissue that lies beneath the enamel, and is what gives teeth their color.
Once tooth enamel is damaged, it cannot be restored. Enamel can be restored to some extent by improving its mineral content. Enamel is the durable part of the human body.
While toothpaste and mouthwash can never "rebuild" teeth, they can contribute to this remineralization process.
Thus, the most durable part of the human body is Tooth Enamel.

A substrate is a molecule that an enzyme reacts.
enzymes catalyze chem. reactions with substrates. Substrates transform into 1 or more products. released from " active site," substrate is then able 2 receive another substrate molecule.
Answer:
An enzyme is catalyzing a reaction.
Explanation:
Two substrates bind to the active site of the enzyme. The enzyme catalyzes the reaction (lowers the activation energy needed to complete the reaction), and the result is the final product: two substrates bound together, and an enzyme that can go on to catalyze more reactions.

Answer:
True
Explanation:
The Long and Diffusion Path can Help the exchange surface to increased rapidly in a long diffusion path. in other words it grows faster.
If the diffusion path is long, the effectiveness of an exchange surface is improved is false.
What is diffusion?Diffusion is defined as the net movement from an area of higher concentration to an area of lower concentration caused on by the dispersal of any material's in-solution or gas-particle particles.
Diffusion is the process by which dissolved chemicals enter or exit cells.
What are the parameters that affect the diffusion?the three parameters that affect diffusion are
