Which statement best describes an organ? the basic unit of all living things; a building block a group of tissues joined together to perform a specific function the process in which tissues combine the smallest unit in a system that can function on its own

Answers

a group of tissues joined together to perform a specific function

Different types of tissues work togeether to carry out a function

a group of cells that work together to perform a common function.

Explanation:

a) Certain bacteria living in the roots of plants convert nitrogen to a form plants can use, and animals obtain their nitrogen by eating those plants.

Explanation:

Biological nitrogen fixation is a process by which soil bacteria traps the atmospheric nitrogen and convert it into organic compounds such as ammonia, nitrates and nitrites. These compounds are easily absorbed by the plant roots from soil. The plants use these forms of nitrogen to produce amino acids required for the synthesis of proteins and nucleic acids necessary for the plant growth.The animals eat these plants and obtain nitrogen so as to obtain energy and maintain the cellular metabolism. The nitrogen in the plant food facilitates the synthesis of amino acids in the animals necessary for production of proteins and nucleic acids.

On the basis of the above description, a) Certain bacteria living in the roots of plants convert nitrogen to a form plants can use, and animals obtain their nitrogen by eating those plants is the correct option.

A. The longer the life cycle, the larger the organism

Explanation:

Small animals ot insects usually die quickly, take a tree frog for instance it only lives for 5 years compared to an orca whale who live for 50-80 years. In conclusion, the larger the organism longer the life cycle.

I think D. The shorter the life cycle, the greater the chance of reproduction.

A group of tissues joined together to perform a specific function

Explanation:

group of tissues -> organ

D

Explanation:

You always want to put it in order. You never want to put the best part in the beginning. That as always left at the end. This is because it keeps the audience or the reader more into the story where they want to keep on reading till the end. if you put it at the beginning and then there's no reason to keep on reading it would have been a waste of time writing the whole story.

Explanation:

D. The organism is eukaryotic because it has membrane-bound organelles.

Cells are the basic microscopic units of all organisms. There are two cell types, Prokaryotes and Eukaryotes.

Prokaryotic ( meaning pro: before and Karyon: for kernel/nut) describes organisms which don’t have a cell nucleus or other organelles surrounded by membranes. Eukaryotic  (eu meaning true), are organisms with a cell nucleus and several other organelles surrounded by membranes. Example prokaryotes do not contain: nuclei , Golgi apparatus, chloroplasts, mitochondria

Both may contain a cell wall (seen in eukaryotic fungi and plant cells)

Arranged in a phospholipid bilayer, the membrane is semi-permeable; allowing entry into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water and hydrophilic molecules to move across the membrane along the concentration gradient.

Their structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates. In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:

may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins
