The use of restriction enzymes and electrophoresis to generate a map of the DNA molecule is known as

Answers

The use of restriction enzymes and electrophoresis to generate a map of the DNA molecule is known as RESTRICTION MAPPING. This technique is used to map an unknown fragment of DNA.

Restriction enzymes are enzymes that cut a DNA fragment at specific nucleotides sites, thereby generally smaller fragments of DNA.

Restriction mapping is a strategy used to map unknown fragments of DNA by digesting them into smaller fragments and then identifying the specific sites of the DNA breakpoints.

Restriction mapping can then be used to create a diagram of fragments of DNA marked with specific sites where they are cut by specific restriction enzymes.

What can bacteria do with “broken down” materials ?

Answers

Bacteria have the ability to break down dead organisms into smaller particles and create new compounds. We use decomposers to restore the natural nutrient cycle through controlled composting. Bacteria secreting enzymes out of their cells into the soil or dead organism. The enzymes digest the organic material. When they break down organic material, they give off heat. Billions of aerobic bacteria working to decompose the organic matter in a compost pile causes the pile to warm up. As the temperature rises, different organisms thrive.

Write a hypostasis based on observations on identifying unknown materials and scientific principals.

Answers

Answer:

Until the past decade, scientists, research institutions, and government agencies relied solely on a system of self-regulation based on shared ethical principles and generally accepted research practices to ensure integrity in the research process. Among the very basic principles that guide scientists, as well as many other scholars, are those expressed as respect for the integrity of knowledge, collegiality, honesty, objectivity, and openness. These principles are at work in the fundamental elements of the scientific method, such as formulating a hypothesis, designing an experiment to test the hypothesis, and collecting and interpreting data. In addition, more particular principles characteristic of specific scientific disciplines influence the methods of observation; the acquisition, storage, management, and sharing of data; the communication of scientific knowledge and information; and the training of younger scientists.1 How these principles are applied varies considerably among the several scientific disciplines, different research organizations, and individual investigators.

Ovulation is the production of an ovum that occurs each month.
Ovulation is the monthly discharge of the uterine lining.

Answers

Answer:

b. Ovulation is the release of a mature ovum, which occurs once each month.

Explanation:is correct. post protected

Ovulation is the release of a mature ovum, which occurs once each month. The correct option is B.

What is ovulation?

The process of an egg being released from the ovary is called ovulation. The egg is released and travels down the fallopian tube, where it remains for 12 to 24 hours before being fertilised.

Although ovulation is necessary for conception, more than simply an egg is required. For instance, there needs to be a clear path to the egg. A blocked fallopian tube prevents pregnancy from happening.

Around the time of ovulation, you could notice that your cervical mucus is wetter, clearer, and more slippery. After ovulation, there is a slight increase in body temperature that you might be able to measure with a thermometer.

Thus, the correct option is B.

most of the energy that your brain uses comes from

Answers

Answer:

Glucose

Explanation:

The brain is an energy-hungry organ. Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake. Because the brain demands such high amounts of energy, the foods we consume greatly affect brain function, including everything from learning and memory to emotions.

Just like other cells in the body, brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the foods we consume daily and is regularly delivered to brain cells (called neurons) through the blood.  

Studies suggest the quality of the foods consumed over a lifetime affects the structure and function of the brain. For instance, the consumption of omega-3 fatty acids found in fish provides structural material to maintain neurons. Studies also suggest omega-3 fatty acids are essential for the transmission of information between brain cells. In contrast, foods that are rich in sugars and saturated fats have been found to promote oxidative stress, which leads to damage to cell membranes.  

The food you eat also affects molecules in the brain that support cognition. Some foods, such as those with turmeric, support cognition by helping to maintain molecular events related to energy metabolism.

Recent studies suggest lifestyle choices that affect the metabolism of nerve cells, such as diet and exercise, may in some cases provide a non-invasive and effective strategy to counteract neurological and cognitive disorders.

A student is conducting an experiment with biochemical reactions and notices that at high temperatures, the reaction rate decreases significantly.

Which statement best explains the decrease in reaction rate?


The bonds of the substrate were breaking.

The enzyme bonded with the substrate.

The enzyme denatured and changed shape.

The activation energy was increasing.

Answers

Answer:

The enzyme denatured and changed shape

Explanation:

Enzymes are proteins, which can only function properly within a certain range of temperatures- when things get too hot, proteins undergo a structural change and are considered to be 'denatured'. This means that enzymes will not be able to function properly under those high temperatures, because the substrate bonding site would no longer be the right shape for said substrate.

The statement best explains the decrease in reaction rate is the enzyme denatured and changed shape. Thus option 3 is correct.

What are enzymes?

Enzymes are defined as a material that functions as a catalyst in living things, controlling the pace at which chemical processes take place without changing the substance itself.

There are six types of enzymes.

Some rotifers are really planktonic and free-swimming, while others travel around a substrate via inchworming, and some are sessile and reside inside tubes or gelatinous holdfasts.

About 25 species are sessile or planktonic, colonial (such as Sinantherina semibullata), and some rotifer species have evolved four moveable toes that are equipped with pedal glands to facilitate swimming and crawling.

Rotifers swiftly colonize new environments and transform primary production (algae and cyanobacteria) into a form that is secondary consumers.

Answers

Given our understanding of the situation, we can confirm that a fossil classified as a transitional form, will show characteristics both of its ancestors and of the descendants that derived from it.

Transitional fossils are just that, fossilized remains of a transitional phase of evolution. What this means is that as species evolve, there will always be a point in time where a species is at a halfway point in between the species from which it comes, and the species that it will become.

These fossils, due to being a halfway point, will have characteristics that belong to their ancestors, but also characteristics that belong to their descendants, which is only logical considering that evolution is a process that spans many generations, not something instant.
