Which of the following functions at the same organizational level as the kidney in the human
excretory system?

Answers

Answer:

Its the Urinary bladder

Explanation:

A. skeleton

B. epithelial tissue

C. urinary bladder

D. a squamous cell

The correct answer as to which functions at the same organizational level as the kidney in the human excretory system would be the urinary bladder. The correct option would, thus, be C.

There are 4 progressive levels of organization as far as life is concerned. These are:

celltissuesorganssystems

The cell is the basic unit, tissues are made of 2 or more cells, organs are made from multiple tissues, while systems are formed from numerous organs.

The kidney is at the organ level and so is the urinary bladder. Skeleton is a system made from different organs, epithelia tissues are tissues, while squamous cells exist at the cellular level.

Answers

Answer:

only glucose

Explanation:

The second student set up solutions that were in equilibrium.

On which principle Dialysis is based?

Dialysis is based on the principles of osmosis, meaning the net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration. If the solute concentrations are the same on each side of the membrane, this spontaneous movement will not occur.

In passive diffusion, the small water molecules can move across the phospholipid bilayer seen in blue. This layer acts as a semi-permeable or selectively permeable membrane; its hydrophilic heads are attracted to water (seen facing outwards) while its water-repellent hydrophobic tails face towards each other- allowing  molecules of water to diffuse across the membrane along the concentration gradient.

Therefore, the second student set up solutions that were in equilibrium.

Answers

Answer:

The correct answer is -

Protein - amino acids

Glycogen - glucose or monosaccharides

Fats - fatty acids

Explanation:

Once protein sources reach the stomach of an individual, An enzyme called proteases and HCl break these proteins into small amino acid chains that were bonded with a peptide bond, thus protein macronutrient is absorbed in the form of amino acid.

Glycogen is stored in the muscles and liver for energy and digested into glucose by enzymes called amylase and maltase.

Fats are the main source of fatty acid in the body and help in providing fatty acid for the body requirements.

Do plants need to eat?Or do they acquire energy through a method different from animals?Write down the differences on how a tree and an ostrich acquire the energy they need for survival.

Answers

For the first half of your question, plants do need to eat. In fact, they are autotrophs, which means they are self feeders.

Plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.

What are Autotrophs?

Autotrophs are the organism that can produce its own food using light, water and carbon dioxide or some other chemicals. They are also known as primary producers.

The most familiar type of autotrophs are plant but apart from plants many different types of autotrophic organisms are there. For example, algae which live in water, phytoplankton which live in ocean and some type of bacteria.

Mostly autotrophs used the process called photosynthesis to make their own food. In this process, Autotrophs used energy from the Sun to convert water obtained from the soil and carbon dioxide obtained from the air to produce a carbohydrate called Glucose . It give energy to the plant.

Some rare autotrophs produces food through a process called Chemosynthesis . In this process, they make their own food using energy from chemical reaction combining Hydrogen Sulphide or Methane with oxygen . Organism that uses Chemosynthesis for making their food lives in extreme environment . For example, Bacteria live in active volcanoes oxidize sulphur to produce their own food.

Thus, plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.

What is the level of organization?

The level of organization may be defined as the process of sequence from the structures that are simplest in nature. It is usually defined by part-whole relationships, with things at higher levels being composed of things at the next lower level.

In organisms, a cell is the fundamental structural and functional unit of life. The collection of cells constitutes the formation of tissue which makes an organ that plays a specific function. Groups of organs form organ systems. While all cells, tissues, organs, and organ systems combine in order to form multicellular organisms.
