Answer:

Basically, primary succession is a change in vegetation which occurs on previously unvegetated terrain (Barnes et al. 1998). Examples of where primary succession may take place include the formation of new islands, on new volcanic rock, and on land formed from glacial retreats.anation:

Three cells each contain a 98% water wash were soaked in different solutions cell number one is so funny solution containing 100

stepladder [879]

Answer: Cell number one is an hypotonic solution, cell number two is an isotonic solution, and cell three is an hypertonic solution.

Explanation:

Cell number one which is a 98% water content is added the 100% water solution, water moves from low to high concentration. Therefore, the water moves from the solution into the cell, which is hypotonic.

Cell number two which is a 98% water content added with a 98% water solution. These two solutions are equal to one another, so the water does not move. This is isotonic.

Cell number three which is a 98% water content added with a 80% water solution. Water moves from high to low concentrations, so water moves from the cell to the solution. The water leaves the cell, which is an hypertonic.

ANEK [815]

Answer:

T. Natural Reseeding.
D. Species Diversity
A. Ecosystem Diversity.

Explanation:

Natural reseeding uses natural elements and actors to plant the seeds of trees. These elements and actors include water, wind, birds, rodents and other actors capable of scattering seed.

Species diversity is what defines the differentiation between the different species in an ecosystem and Ecosystem diversity relates to how biological communities/ ecosystems can be different from each other based on the organisms and food chains available in each.

Evidence that cytoskeletal elements have ancient origins comes from the: sequence similarities of cytoskeletal elements when com

Gnesinka [82]

Answer:

All of these choices are correct.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles in all living organisms such as trees, birds, and bacteria include; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, cytoskeleton, etc.

Cytoskeleton refers to a structure consisting of filaments and tubules which help to maintain internal organization and support the shape of the cells. It comprises of three (3) main filaments and these includes: actin filaments, intermediate filaments and microtubules.

Generally, there are numerous evidence that cytoskeletal elements have ancient origins and they include all of the aforementioned facts.

Hypothesize why only one genus and species remains in the hominin group

laiz [17]

<span>Modern humans have been around for a very short period of time. There are differences in race, asian people tend to be smaller, stuff like that. The problem is different races marry and those genes mix. If Asians only married pure blood Asians, Africans only married and procreated with other Africans thanks in hundreds of thousands of years different sub species would most likely start to occur. Seeing as how human population is all connected today, that won't happen.</span>
