Q3. Why do we need to break big molecules into smaller molecules? ​

Answers

Answer:

In order for them to be quickly and easily absorbed.

________________________________________________

Short Answer:

Enzymes help break down large molecules for us since certain of their components are the only ones that are useful to us. In order to create proteins, lipids, and other components necessary for survival, the tiny molecules become soluble and are quickly taken into the circulation. Additionally, they could need to travel through some membranes, therefore when they are little, they can do so without difficulty.

________________________________________________

Long Answer:

The nutrients in food must pass the gut lining in order to exit the digestive system and enter our blood. This absorption occurs in the ileum and jejunum regions of the gut. In some regions, the gut lining is brimming with chemical systems that may latch onto the food's smaller molecules and "chaparone" them across the gut and into the liver. These "chaparone" molecules can hold small peptides and amino acids but not whole proteins. Greater floor fragments do not absorb. Without "chaparones," some of the stomach-digested products pass through the gut's pores, but they must be smaller than the pores. Only tiny pieces and certain fragments with complementary "chaparones" of the food we eat are molecular fragments that are absorbed. A number of gastrointestinal conditions are caused by an imbalance in the gut's capacity to absorb nutrients. One condition where iron is not effectively absorbed is Cooly's anemia. Iron deficiency affects Cooly's anemia patients, even if their stomachs digest food correctly and they have normal iron absorption. Catabolism is the process of dissolving big molecules into smaller ones. Catabolism releases energy by rupturing bonds. Anabolism creates new connections and needs energy to function. Catabolic reactions (destructive or biosynthetic process) breaks down large molecules and release energy

C. More biodiversity increases stability
D. More biodiversity decreases stability

Answers

The ecology is absolutely necessary for biodiversity. Ecosystem stability also rises as a result of increased biodiversity.

What do you mean by biodiversity?

The term "biodiversity" is used to describe the variety of species that can be found on earth. It can include things like plants, animals, bacteria, fungi, and microbes. The diversity of life on earth is immense; while many species are still waiting to be discovered, many more have already gone extinct. The ecosystem is composed of every single living thing. It also covers their surrounding environment and how people interact with them.

The ecosystem depends heavily on the various species. Therefore, the ecosystem's ideal balance is impacted when a single species goes extinct or is lost. Plants use the energy from the sun as part of the ecosystem's cycle.

the growth of a plant in size is regulated by a plant hormone. explain​

Answers

Abscisic acid

Abscisic acid serves as an antagonist to Gibberellic acid. It is also known as the stress hormone as it helps by increasing the plant-tolerance to various types of stress.

[tex]\underline{\color{yellow}{hope \: its \: help \: you}}[/tex]

Plant hormones, also known as phytohormones, regulate growth by influencing cell division, elongation, differentiation, and various physiological responses in plants. These hormones include auxins, gibberellins, cytokinins, abscisic acid, and ethylene.

Plants regulate their growth in size through the action of plant hormones, also known as phytohormones. These are chemical messengers produced by various parts of the plant, such as the roots, stems, leaves, and flowers.

There are several types of plant hormones, each with specific roles in growth regulation:

Auxins: These hormones are responsible for cell elongation and differentiation. They promote growth by increasing the flexibility of cell walls, allowing cells to elongate. Auxins are also involved in tropisms, which are growth responses to external stimuli like light (phototropism) or gravity (gravitropism).

Cytokinins: Cytokinins promote cell division and growth in areas such as roots, shoots, and fruits. They play a role in controlling the balance between shoot and root growth.

Gibberellins: Gibberellins are involved in stem elongation, seed germination, and flowering. They stimulate cell division and elongation, leading to increased plant height and size.

Abscisic Acid (ABA): ABA is often called the "stress hormone" because it regulates responses to stress conditions like drought, cold, and salinity. during adverse conditions.

Ethylene: Ethylene is a gas that regulates fruit ripening, senescence (aging), and responses to mechanical stress. It plays a role in processes like leaf abscission (shedding) and root growth inhibition.

Thus, plant hormones, also called phytohormones, control growth in plants by affecting cell division, elongation, differentiation, and a variety of physiological responses.
