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.

Answer:

1. Protein - build lean muscle and strengthen tendons

2. Lipids - insulation and long-term energy

3. Carbohydrates - provides quick, easily digested energy

4. Nucleic Acids - repair and replicate DNA and RNA

Explanation:

a. Think of protein as what helps your muscles grow and strengthen

b. Think of lipids as fats (blubber, the extra fat, helps insulate seals from the cold)

c. carbohydrates are found in starch and bread products, and are used to help build up energy prior to marathons.

d. nucleic acids -  think of nucleus; it is where genetic material is located, and also where DNA and RNA is located.

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.

Answer:

may cause negative side effects

Explanation:

Answer:

May cause negative side effects.

Explanation:

I took the test

Genetic Engineering is used to put genes from one organisms into another. The new organism can reproduce. And while it may seem like it's the answer the nutrition value and scarcity of food is in no way impacted. It's not like cloning. Where more are being created in large amounts with similar diets. They can be cross-pollinated with organisms with different diets. So the only obvious answer would be the negative side effects.

Explanation:

enzyme + substrate complex =

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.

The order is tricuspid valve, right ventricle, p. valve, p. artery, lungs, left atrium, mitral valve, left ventricle, aortic valve, aorta, tissues and vena cava.

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.

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.

Answer:

The A band stays the same width and, at full contraction, the thin filaments overlap. ... The I band contains only thin filaments and also shortens. The A band does not shorten—it remains the same length—but A bands of different sarcomeres move closer together during contraction, eventually disappearing.

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.

Dolphins are highly sociable mammals that establish close links with other individuals of the same species and even with dolphins of other species sometimes.

Similarities is that they live in water and they are Viviparous (animals that are born out of the womb)

Like every mammal, dolphins are warm blooded.

Unlike fish, who breathe through gills, dolphins breathe air using lungs.

Short paragraph:

Homeostatis is the process by which the body maintains a stable internal environment. The hypothalamus is a part of the brain that regulates many key body processes. It works to restore the system to its normal state when an internal change in one of these systems occurs.

Long paragraph:

The hypothalamus is a part of the brain that regulates many key body processes including internal body temperature, hunger, thirst, blood pressure, and daily (circadian) rhythms. When the brain receives signals from the body about an internal change in one of its systems, it works to restore the system to its normal state. For example, the normal internal temperature for the human body is approximately 98.6 degrees Fahrenheit. If the body temperature rises because of exercise, the body will try and cool itself off. This happens through coordination between the hypothalamus and the various body systems that are affected.

Answer:

The process through which creatures evolve is known as evolution. Mutations cause genetic variety throughout populations, and the ecosystem works with this diversity to select people who are most suited to their surroundings. Eventually, a species can develop into a plethora of others; as a theory suggests that sapiens started as monkeys but evolved into the humanoid beings that we are today. In biology, adaptation is the procedure where a species fits to its habitat; it is the outcome of natural selection acting on hereditary diversity over numerous generations. Survival the fittest is a saying that suggests the fittest survive, not the weak. This is commonly seen in everyday life, whether with humans, animals, plants, it holds the same meaning. An example would be that a person in better physical and mental health would go farther and live longer than one with weak physical and mental health.

The concept of "survival of the fittest" is a key tenet of evolution, which refers to the idea that individuals with traits that provide them with a competitive advantage in their environment are more likely to survive and reproduce than those without these traits. This process of natural selection leads to the gradual accumulation of beneficial traits in a population, resulting in adaptation and evolution over time.

Adaptation refers to the process by which organisms develop characteristics that allow them to better survive and reproduce in their environment, such as camouflage or the ability to digest new types of food.

Evolution refers to the broader process of change over time in a population's genetic makeup and physical characteristics, resulting from the interaction between genetic variation, natural selection, and other factors. Together, these concepts help explain how organisms are able to adapt and change over time, resulting in the diversity of life that we see today.

The study of evolution has important implications for understanding the history and development of life on Earth, as well as for addressing modern challenges such as biodiversity loss and climate change.
