What happens when the nucleotides in a DNA synthesis reaction are radioactive?

Answers

Answer 1
If a cell is grown in a medium containing radioactively labeled thymidine--which is one of the nucleotides needed to synthesize DNA--after the first round of replication, all of the DNA molecules will have one labeled strand and one unlabeled strand. Why? Because the radioactively labeled thymidine will be incorporated into the newly synthesized strands. If the cell undergoes ANOTHER round of replication in the same medium, the same sequence of events will occur.

The IQ range that indicates moderate mental *********** is A. 70-79.

What is an IQ?

IQ stands for Intelligence Quotient and is a measure of cognitive abilities and intellectual potential. It is determined through standardized tests that assess various cognitive skills, including problem-solving, memory, and analytical thinking.

The average IQ score is set at 100, with scores ranging from 70 to 130 considered to be within the normal range. Scores below 70 indicate varying degrees of intellectual disability, while scores above 130 suggest above-average intelligence.

While IQ scores can provide insight into a person's cognitive abilities, they do not account for other factors, such as emotional intelligence or creativity, that may contribute to overall success in life. It is essential to recognize that IQ tests have limitations and should not be used to label individuals or limit their potential.

This range is considered to be a mild to moderate intellectual disability, indicating limitations in adaptive functioning and potential need for support in daily life activities.

Blood pressure is a needed thing in a body. It gets blood to your organs and everywhere that needs it. If it didn't work, many things could happen.

Too high BP(hypertension):

If your blood pressure is too high, it can cause ruptured vessels, heart attacks, strokes, heart failure, which is where the heart enlarges too much to continue pumping blood at the adequate pressure/speed, kidney disease/failure, which would be from damage to the arteries around the kidneys, vision loss due to damage to the vessels in the eyes, angina, which is chest pain due to narrowed vessels in the chest, some forms of which may cause heart attacks.

Too low BP(hypotension):

If you're experiencing hypotension, there are many things commonly associated with it. These are dizziness, fainting, nausea, blurred/fading vision, lack of focus, and fatigue. If hypotension becomes extreme, it can cause someone to go into shock, which is life threatening and can and will cause death.

Answers

Answer: C. It involves a transfer of energy.

Using the scientific definition, the statement that is always true of work is it involves a transfer of energy. The correct option is C.

What scientific theories?

Scientific theories are the theories that are given by scientific facts and information. These theories are based on observation of natural things and places.

There is the transfer of energy in the natural world. Every organism and plant is connected with each other in the form of a transfer of energy. This is called a food chain.

In the food chain, the organism is divided into different levels. These levels are based on their food. They are autotrophs, heterotrophs, and decomposers. Autotrophs have the largest amount of energy.

Thus, the correct option is C) It involves a transfer of energy.

The temperature of the interior of the human body is about 37oC (98.6oF), regardless of the air temperature. Explain the importance of constant body temperature given the role of enzymes as catalysts in the body.

It’s very important because let’s say you’re outside on a hot summer day and you’re sweating a lot, sweat would be to help you cool down but you would be losing water in the process. If you stop sweating but you’re still hot you would sweat out and this would cause a heatstroke

Hope this helps

It is critical that we sustain an optimal temperature for our body's enzymes. When it gets too hot, our enzymes denature and become inactive/lost their function. If the temperature is too low, the enzymes will become ineffective.

What is homeostasis?

Homeostasis is the state of constant internal, physical, and chemical assumption is supported by living systems in biology.

This is the state of the organism's optimal functioning, and it includes many variables, such as core temperature as well as fluid balance, getting kept within certain pre-set limits.

Enzymes can only function when the body's temperature remains constant. As a result, homeostasis becomes an important part of the body's metabolism.

Homeostasis maintains optimal conditions for enzyme action and all cell functions throughout the body.

It is the preservation of a constant internal environment in the face of changing internal and external conditions. These include blood glucose concentration control in the human body.

Thus, having an optimum temperature is essential in functioning of enzymes.

cholesterol**

Cholesterol makes up cell membranes and is used to create hormones.

Cholesterol is a necessary lipid for the body as it contributes to the formation of cell membranes and hormones. However, high amounts of cholesterol in the blood have harmful consequences for health.

Cholesterol has different functions in the body such as:

- Formation of structures: It is one of the main components of the plasma membranes of animal cells.

- Contributes to the formation of hormones: sex hormones (progesterone, estrogens, and testosterone), corticosteroid hormones (cortisol and aldosterone).

- Contributes to the metabolization of calcium to obtain vitamin D.

Additionally, the options hydrocarbon (natural chemical compound obtained from the earth to be used as fuel), starch (natural macromolecule that contributes to the human digestion process) and glucose (the most abundant chemical compound in nature that serves as a source of energy for organisms) are not correct options, because these substances do not have the function of forming cell membranes and creating hormones.

Cuando la célula madre se divide varias veces de forma consecutiva y los núcleos se rodean del citoplasma dentro de ella, es una reproducción tipo: esporulación.

Explanation:

En la reproducción asexual, un solo ser origina nuevos individuos iguales entre si e iguales a su progenitor. Este tipo de reproducción es común en ciertos invertebrados, en las bacterias y en los protozoarios. La esporulación es uno de los tipos de reproducción asexual, esta consiste en varias divisiones del núcleo que se envuelve de fragmentos citoplasmáticos, originando muchos descendientes genéricamente idénticos. Dicha reproducción permite la formación de esporas y la liberación de las mismas cuando las paredes de la célula se rompen. Se observa en ciertas especies de protozoarios.

Shameeka is studying for an exam. She took the notes below about calcium and chlorine, which are known to form ionic bonds.

Calcium, which is a metal, donates 2 electrons to chlorine.
The individual calcium atoms become ions with a negative 2 charge.
The bond between calcium and chlorine makes the atoms stable.
Calcium and chlorine attract each other.

Which best describes Shameeka’s error?

Calcium is a metal, so it donates protons, not electrons.
The individual calcium atom has a positive, not negative, 2 charge.
The bond formed makes the atoms unstable, not stable.
Calcium and chlorine repel, not attract, each other.

Answers

Answer:

The individual calcium atom has a positive, not negative, 2 charge.

Explanation:

The error in her study is in the second line of her note which suggests that the individual calcium atoms becomes ions with a negative 2 charge.

When atom loses electrons, it has a net positive charge on it. Not a negative charge. This is because the number of protons is now more than electrons. Therefore, a net charge on the calcium atom will be a positive one. This is her mistake.

Answer:

B) The individual calcium atom has a positive, not negative, 2 charge.

In Homes, solid wastes usually include used plastic, shattered glass, metal objects and so on.

Plastic wastes and metals could be recycled and refined to make rubber and aluminium spare parts, hence, serving as raw materials.

Therefore, since solid materials take very long to Decay, hence recycling of the waste and their use in organic products are always good means of disposal.
