What is the relaxed form of dna in a cells nucleus?

Answers

Answer:

The relaxed form of DNA that can be found in the nucleus is referred to as chromatin. This form of DNA is observed when the cell is not dividing.

Explanation:

hope this helps

The relaxed form of DNA in a cell's nucleus is called chromatin.

CHROMATIN:Chromatin is a complex of DNA and histone proteins within the cell's nucleus. The DNA is too long to fit into the cell's nucleus, hence, is coiled around proteins called histones.

This complex forms the structure called chromatin, which then condenses during the prophase stage of cell division to form a more compact structure called chromosome.

Therefore, it can be said that the relaxed or uncondensed form of DNA in the nucleus of a cell is called chromatin.

D - design a device that can throw an object at least 15 metres

Answer:

D. Design a device that can throw an object at least 15 meters.

Explanation:

First of all, the object shown as you may be able to tell, look like a catapult. It also shows the top end of it holding a ball, getting ready to launch it. It then shows a line of the ball traveling after being launched. The balls land of the ground at 15 meters. From this iformation you look at the options:

A. Design an object that is 10 meters tall.

No, because 10 meter is just the highest point of the ball being launched.

B. Design a vehicle that can travel across a 10-meter feild.

No, because it is the ball that is traveling, not the catapult.

C is about a vehicle traveling again, so eliminate that too.

D. Design a device that can throw an object at least 15 meters.

This describes exactly what we soo in the picture. Meaning D is correct.

Postganglionic sympathetic axons are carried from the sympathetic trunk to all spinal nerves through ______.

Answers

Answer:

gray rami communicantes

Explanation:

Postganglionic sympathetic axons are carried from the sympathetic trunk to all spinal nerves through gray rami communicantes. The sympathetic nervous system is almost connected to all parts of the body.

What is the nervous system?

The nervous system is made up of neurons that are connected to each other and send the message for action to different parts of the body. The whole nervous system of the body is divided into three parts: the central nervous system, the peripheral nervous system, and the autonomic nervous system.

The central nervous system is composed of the brain and spinal cord, while the autonomic nervous system is composed of the sympathetic and parasympathetic nervous systems. The peripheral nervous system includes the nerves of the brain and spinal cord that are derived from these two organs. The sympathetic nervous system activates the majority of the organs in times of danger, whereas the parasympathetic nervous system is associated with rest.

Hence, Postganglionic sympathetic axons are carried from the sympathetic trunk to all spinal nerves through gray rami communicantes.

How does your body respond to an increase in the waste products of energy production

Answers

Answer:

Energy is delivered to the body through the foods we eat and liquids we drink. Foods contain a lot of stored chemical energy; when you eat, your body breaks down these foods into smaller components and absorbs them to use as fuel. Energy comes from the three main nutrients carbohydrates, protein, and fats, with carbohydrates being the most important energy source. In cases where carbohydrates have been depleted, the body can utilise protein and fats for energy. Your metabolism is the chemical reactions in the body’s cells that change this food into energy.

Most of the energy the body needs is for being at rest, known as the Basal Metabolism. This is the minimum amount of energy the body requires to maintain its vital functions such as breathing, circulation and organ functions. The rate at which energy is utilised for such functions is known as the Basal Metabolic Rate (BMR) and varies based on genetics, sex, age, height and weight. Your BMR drops as you get older because muscle mass decreases.

Optimal energy metabolism requires getting sufficient nutrients from our foods, otherwise our energy metabolism underperforms and we feel tired and sluggish. All foods give you energy and some foods in particular help increase your energy levels, such as bananas (excellent source of carbohydrates, potassium and vitamin B6), fatty fish like salmon or tuna (good source of protein, fatty acids and B vitamins), brown rice (source of fibre, vitamins and minerals), and eggs (source of protein). There are actually many foods that provide an abundant amount of energy, particularly those packed with carbohydrates for available energy, fibre or protein for a slow release of energy and essential vitamins, minerals and antioxidants.

Foods are metabolised at a cellular level to make ATP (Adenosine Triphosphate)

by a process known as cellular respiration. It is this chemical ATP that the cell uses for energy for many cellular processes including muscle contraction and cell division. This process requires oxygen and is called aerobic respiration.

 

            Glucose + Oxygen → Carbon dioxide + Water + Energy (as ATP)

 

Initially, large food macromolecules are broken down by enzymes into simple subunits in the process known as digestion. Proteins are broken down into amino acids, polysaccharides into sugars, and fats into fatty acids and glycerol—through the action of specific enzymes. Following this process, the smaller subunit molecules then have to enter the cells of the body. They firstly enter the cytosol (the aqueous part of the cytoplasm of a cell) where the cellular respiration process begins.

Answer:

Agriculture gave people the opportunity to create civilizations, fight hunger and work to combat challenges in population growth and climate change.

Explanation:

Another positive development in farming is the rapid expansion of farmers markets. Farmers markets allow small farmers to interact directly with consumers. The food system remains within the local economy by being locally produced and eliminates the need for long-distance transportation. The opportunity to purchase locally grown food proves invaluable as the demand for it rises.

The child having an equal chance of inheriting the dominant allele or the

recessive allele for freckles from her mother is what applies.

The law of segregation by Mendel states that diploid organisms have a pair

of alleles and are passed to their offspring at random.
