A few years after a devastating forest fire, pioneer trees become established. after another 50 years, those trees are replaced

Keith_Richards [23]

Abiotic factors composed of water, light, temperature and air etc. due to fire's this primary succession was completely destroyed. Their remaining organic bodies were decomposed in soil texture.

In order to establish secondary succession there is need of water and light, because water help in translocation of food and nutrients in plants while light is important for photosynthesis.

Photosynthesis need three major components. these are H₂O, CO₂ and light, all these components are abiotic part of ecosystem. However, when secondary succession occurs, then light play a key role in changing the composition of plant community. The best example is the difference in height of plants of different community.

Determine whether each statement describes mitosis, melosis, or both mitosis and melosis.

Kruka [31]

Answer:

This question is incomplete as it lacks statements, the statements and the answers are as follows:

occurs in organisms that sexually reproduce - MEIOSIS

occurs during growth and development - MITOSIS

the DNA is replicated - MITOSIS AND MEIOSIS

occurs in all organisms - MITOSIS

the number of chromosomes remains the same - MITOSIS

the number of chromosomes reduces by half - MEIOSIS

Explanation:

Meiosis and mitosis are both types of cellular divisions that occur in living cells. Mitosis involves the formation of two (2) daughter cells that are genetically identical to the parent cell while meiosis involves the formation of four (4) daughter cells that are genetically different from the parent cell.

The following are characteristics of the two division processes based on this question:

MITOSIS:

- It occurs during growth and development of an organism.

- it involves DNA replication

- it occurs in all organisms since every living organism undergoes growth and development.

- the number of chromosomes after mitosis remains the same in the daughter cell i.e. 2n remains 2n

MEIOSIS:

- It occurs only in organisms that sexually reproduce.

- it also involves the replication of DNA

- The number of chromosomes in the daughter cells is reduced by half i.e. 2n to n.

Llamas have sexual reproduction. Some types of llamas have 74 chromosomes. That is how many chromosomes are in their somatic (bo

Sholpan [36]

Answer: 37 chromosomes.

Explanation: As is typical of mammals, llamas are diploid organisms, meaning that the number of chromosomes in each of their somatic cells is exactly twice of that found in the gametes (the so-called haploid number, referred to as "n"). If a particular species has 74 chromosomes in its somatic cells, we should expect to find 74/2=37 chromosomes in each gamete.

How were you able to determine if something was living, once living, or never living (non-living)?

snow_lady [41]

Answer:

Must have lived before.

Explanation:

For an organism to be classified as once living, an object must have been part of a living organism or is now dead. When a flower is plucked from a plant it is hard to distinguish between when it is considered alive and when it is now considered once living. An example of a nonliving object is an apple or a dead leaf.Apr 22, 2013

Is The sun warms up the swimming pool conduction or radiation

jenyasd209 [6]

Answer:

Given that water is clear and colorless, it seems that it will absorb very little direct radiation from the sun. The sides and the bottom of the pool can however heat it by conduction.

Explanation:

hope it help and if it doesnt sorry;)
