What is the basic difference between primary and secondary succession

Biology

Kobotan [32]3 years ago

Primary succession occurs when there are no remains of the previous ecosystem.
Secondary succession occurs when there are still remains of the ecosystem, so secondary succession kind of has a head start.

How do the small molecules of oxygen and carbon dioxide move through the cell membrane?
iris [78.8K]

Answer:

A.  passive transport by diffusion

Explanation:

Diffusion and osmosis are both types of passive transport. They do not require energy. Diffusion is the general term for the process. Osmosis is the diffusion of water molecules.

Many small, uncharged molecules can cross the cell membrane by diffusion. Oxygen and carbon dioxide are examples of two small molecules that pass the cell membrane by passive transport.

Larger or charged molecules require energy to cross the cell membrane. This is achieved by active transport.

Several students were having a discussion about the role of chromosomes in inheriting traits.
serious [3.7K]

Answer:

Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.  

Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.

Explanation:

Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.  - this is true. Prior to cell division, DNA molecules are organized into large structures called chromosomes. Specific regions of a DNA molecule are called genes. These dictate specific proteins which control our traits.

Genes contain thousands of chromosomes that carry specific information about building proteins for a particular trait.  - this is false - genes are segments of DNA that control specific traits by dictating the structure and functions of proteins. Chromosomes contain thousands of genes

Chromosomes are small sections of DNA that contain specific information about a trait to build proteins that people inherit. The thousands of different chromosomes passed from the parents allow for humans to look uniquely different. - this is false - chromosomes are large structures, genes are the relatively small sections of DNA. Humans have 23 pairs of chromosomes, not thousands.

Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.  - this is true. In diploid organisms, like humans, have two copies of each chromosome. These chromosomes contain slightly different versions of genes, which make us unique.
