Diffusion is a very slow process. If multicellular organisms used diffusion to meet all requirements of food, exchange of gases or removal of wastes it would take too much of time for carrying.

Explanation:

In the given data the amount of calories that  food contain 100 gram of calories or one calories.

An energy unit is a calorie. The terms "calorie" and "calories" are used interchangeably for historical reasons. The heat needed to raise one kilogram of water's temperature by one degree Celsius was the original definition of the big calorie, food calorie, or kilograms calorie (or one kelvin). The amount of heat required to produce the same increase in one gram of water was referred to as the tiny calorie or gram calorie . 1 large calorie is therefore equivalent to 1000 little calorie.

The term "calorie" and the symbol "Cal" usually generally refer to the big unit of energy in nutrition and food research.

Here are some uses of biotechnology in the production of washing powders:

Enzymes: Enzymes are commonly used in washing powders to enhance the cleaning efficiency and remove various types of stains.  Proteases, amylases, lipases, and cellulases are examples of enzymes used in washing powders. These enzymes break down protein-based, starch-based, lipid-based, and cellulose-based stains, respectively, into smaller fragments, making them easier to remove during the washing process.

Bio-surfactants: Surfactants are essential components of washing powders as they help to remove dirt and oil from fabrics. Biotechnology allows for the development of bio-surfactants, which are surfactants derived from biological sources, such as bacteria or yeast. These bio-surfactants are more environmentally friendly than traditional surfactants as they are biodegradable and have lower ecological impact.

Microbial Strains: Biotechnology can be used to isolate, characterize, and optimize microbial strains that produce enzymes or bio-surfactants. Microorganisms, such as bacteria and fungi, can be engineered or selected for their ability to produce specific compounds that enhance the cleaning performance of washing powders.

Genetic Modification: Genetic modification techniques can be employed to enhance the properties of microorganisms used in the production of enzymes or bio-surfactants. This allows for the creation of microorganisms with improved characteristics, such as increased enzyme activity or enhanced stability under varying conditions.

Fermentation Processes: Biotechnology facilitates the use of fermentation processes to produce enzymes and bio-surfactants at a large scale. Fermentation involves the controlled growth of microorganisms in bioreactors, where they produce enzymes or bio-surfactants through metabolic processes. This enables the efficient and cost-effective production of these ingredients for use in washing powders.

Transpiration refers to the process of water loss through the stomata of plants, evaporation is the process of a liquid turning into a gas, while evapotranspiration is the combination of both transpiration and evaporation and refers to the total water loss from a surface.

Transpiration is the process by which water is lost from a plant through small pores called stomata. This water loss can occur through evaporation from the surface of the leaves or stems and serves to regulate the temperature of the plant and maintain water balance.

Transpiration also plays a crucial role in the movement of water and nutrients from the roots to the leaves. It is an important aspect of the water cycle and helps to redistribute water and minerals throughout the plant.

The reflecting telescope gathers more radiation than the refracting telescope. Therefore, option (D) is correct.

Reflecting telescopes use mirrors to gather and focus light, allowing for larger apertures and higher light-gathering capabilities compared to refracting telescopes, which use lenses. This design difference typically gives reflecting telescopes an advantage in terms of gathering more radiation from distant objects in space.

However, without specific information about the sizes or specifications of the telescopes in the pictures, this inference is based on the general characteristics of reflecting and refracting telescopes.

Explanation:

The purpose of the lab is to identify the structures of the digestive and circulatory systems in a rat.

The digestive system of a rat is similar to that of other mammals. It consists of the mouth, esophagus, stomach, small intestine, large intestine, and rectum. The mouth is where food is chewed and mixed with saliva.

The esophagus is a muscular tube that carries food from the mouth to the stomach. The stomach is a muscular sac that churns food and mixes it with gastric juices. The small intestine is a long, coiled tube that absorbs nutrients from food. The large intestine absorbs water from food and stores waste products. The rectum is a muscular tube that carries waste products from the large intestine to the anus.

The gallbladder is absent in rats because they have a different diet than other mammals. Rats eat mostly plant matter, which does not require as much bile for digestion as a diet that is high in protein. Bile is a fluid that is produced by the liver and stored in the gallbladder. It helps to break down fats in food.

The stages of bee development are egg, larva, pupa, and adult. Eggs hatch into larvae, which then transform into pupae. Finally, adult bees emerge and undergo further maturation.

The stages of bee development are:

1. Egg: The bee life cycle begins when the queen bee lays an egg in a honeycomb cell.

2. Larva: The egg hatches into a larva, which is a legless, grub-like creature. The larva is fed a special diet called royal jelly, which stimulates its growth.

3. Pupa: The larva undergoes metamorphosis and transforms into a pupa. Inside the sealed cell, the pupa undergoes various changes, developing into an adult bee.

4. Adult Bee: After completing the pupal stage, the fully developed adult bee emerges from the cell. The bee then undergoes further maturation, such as its exoskeleton hardening, wings expanding, and adult coloration appearing.

It's important to note that there are three castes of bees: queen, worker, and drone. The development process for each caste is similar, but the diet and size of the cells they are raised in differ, leading to their distinct roles within the colony.

Answer:

symbiosis.

Explanation:

The term that you are referring to is symbiosis. (a symbiotic relationship)

Symbiosis is a proximate and often long-term interaction between two or more different biological species.

The generation time of the bacteria in the following culture is approximately 3.01  hours.

To determine the generation time of bacteria, we can use the formula:

Generation time (t) = (Time elapsed (T) / Number of generations (n))

In this case, we have a time difference of 10 hours between the two samples.

To calculate the number of generations, we can use the formula:

Number of generations (n) = log(N₂ / N₁) / log(2)

Where N₂ is the final cell count (10,000 cells/ml) and N₁ is the initial cell count (1,000 cells/ml).

Plugging in the values, we get:

Number of generations (n) = log(10,000 / 1,000) / log(2) ≈ 3.32

Now, we can calculate the generation time:

Generation time (t) = Time elapsed (T) / Number of generations (n)

Generation time (t) = 10 hours / 3.32 ≈ 3.01 hours

Therefore, the generation time of the bacteria in this culture is approximately 3.01 hours.

Volume has the greatest effect on living cell's ability to move material in and out of the cell by diffusion.

Diffusion is defined as the process  of movement of molecules under the influence of concentration gradient. It helps in movement of substances in and out from the cells.

Molecules have the ability  to move from lower concentration region to a region of higher concentration   till the concentration is equal on both sides.

There are 2 types of diffusion :1) simple diffusion 2) facilitated diffusion

Simple diffusion is a process by which substances move across a semi permeable membrane   or from a solution without any aid from transport proteins.

Facilitated diffusion is a passive process of movement of molecules from region of higher concentration to a region of lower concentration.It takes place with help of carrier molecule.
