which of the following are reasons why eukaryotes have a more complex gene regulation than prokaryotes?
-RNA polymerase must have access to the DNA double helix
-RNA polymerase must be capable of binding the promoter

Answers

Answer 1

Option B, RNA polymerase must be capable of binding the promoter Eukaryotic cells are more complex than prokaryotic cells and therefore have a more complex system of gene regulation.

This is because eukaryotic cells contain a nucleus and other cellular compartments, such as the endoplasmic reticulum and Golgi apparatus.  RNA polymerase ,These compartments create a more diverse cellular environment that requires a more sophisticated system of gene regulation to coordinate the expression of genes. Eukaryotic cells also have a greater number of regulatory elements, such as enhancers and silencers, that can control gene expression in a tissue-specific manner. All of these factors contribute to the more complex gene regulation seen in eukaryotic cells compared to prokaryotic cells.

introduction of iron and functions of iron in the human body

Answers

Iron is an essential mineral that plays an important role in many of the body's functions. Here is a brief introduction to iron and its functions in the human body:

Introduction:
Iron is a metallic element that is found in many foods, including red meat, poultry, seafood, beans, lentils, fortified cereals, and some fruits and vegetables. It is also available in supplement form. The human body needs iron to produce hemoglobin, a protein in red blood cells that carries oxygen from the lungs to the rest of the body.

Functions:

Oxygen Transport: Iron is a crucial component of hemoglobin, which helps to transport oxygen from the lungs to the rest of the body.
Energy Production: Iron is involved in energy production, helping to create ATP (adenosine triphosphate), the body's primary energy source.
Immune System Function: Iron is also important for a healthy immune system, as it helps to produce white blood cells that fight infection.
Brain Function: Iron is essential for brain function, as it is involved in the production of neurotransmitters and myelin, which protects nerve fibers in the brain and spinal cord.
Collagen Synthesis: Iron is involved in the synthesis of collagen, a protein that is important for the health of skin, bones, and other tissues.
It is important to maintain an adequate iron intake, as a lack of iron can lead to iron-deficiency anemia, a condition in which the body doesn't have enough red blood cells to carry oxygen. This can result in fatigue, weakness, and other symptoms
INTRODUCTION OF IRON

Iron is a chemical element with the symbol Fe and atomic number 26. It is a metal that is essential for human health and is involved in many biological processes in the human body. Some of the key functions of iron in the human body include:

Oxygen Transport: Iron is a critical component of hemoglobin, a protein in red blood cells that carries oxygen from the lungs to the tissues throughout the body.Energy Metabolism: Iron is involved in various metabolic processes that produce energy for the body, including the production of ATP.Enzyme Function: Iron is a cofactor for several enzymes that are involved in various metabolic reactions.Immune Function: Iron is essential for the normal function of the immune system, including the production of white blood cells.Brain Development: Iron is important for proper brain development, especially in infants and children.

It's important to have enough iron in the diet to maintain good health. However, too much iron can be harmful, so it's important to consult a doctor before taking iron supplements.

c.Several hours after the meal, the blood glucose level will increase sharply because of an increase in the amount of glucagon secreted.
d.The blood glucose level will not change after the 5 p.m. meal because the person has already consumed two meals and the blood glucose level has been adjusted to a steady-state level.

Answers

The best forecast for what will happen to the blood glucose level if the person consumes another meal at 5 p.m. is that it will rise immediately after the meal and then insulin will be released to offset the rise. The right response in this case is option B.

In response to a meal, blood glucose levels rise and stimulate the pancreas to release insulin, which facilitates the uptake of glucose by cells and reduces the blood glucose levels. Insulin also stimulates the liver to store glucose as glycogen and reduces the production of glucose.

So, it can be said that insulin helps to regulate blood glucose levels by increasing glucose uptake and storage, and decreasing glucose production.

plant mass actually comes from

Answers

Answer:

One of the earliest experiments to determine the answer to this question was performed by van Helmont in the 1600s. He planted a 2 kg willow tree in a sealed pot that contained 90 kg of dried soil. He watered the pot with rainwater. After five years, he found that the willow weighed 77 kg while only 60 grams of soil were missing. He concluded that the added weight of the plant arose out of the water. [1]

In light of our knowledge of photosynthesis, we know that the weight added is due to both atmospheric carbon dioxide and water. What's interesting is that John Woodward discovered that more than water contributed to the mass of the plant in 1699.[2] About 100 years later, in 1796, Senbier showed that carbon dioxide was utilized by plants in photosynthesis. In 1797, de Saussure demonstrated that both carbon dioxide and water, along with light, are required for plants to gain mass. [3], [4]

So in the end, we (mostly) add mass via

nCO2+nH2O+light→(CH2O)n+nO2

(CH2O)n can be utilized in many forms. For example, cellulose is a polysaccharide formed from many units of glucose C6H12O6 linked together.

Photosynthesis does account for most of the mass that is added within a plant. Of course, there are other important nutrients that plants need. One of the most important is magnesium, which is at the centre of the chlorophyll molecule. These other nutrients come from the soil.
