The birds, because we can see from the food web that the bird eats both grain, a producer, and grasshoppers, a consumer.

Read each of the sentences that describe what happens either during mitosis or meiosis. Drag each sentence into the correct box.
kiruha [24]

Answer:

MEIOSIS:

- Each replicated chromosome pairs with its corresponding homologous chromosome

- Tetrads form and crossing over sometimes occur

- Paired homologous chromosome line up across the center of the cell.

- Four haploid daughter cells form that are not identical to the parent cell

MITOSIS:

- Homologous chromosomes do not pair

- One row of chromosomes line up at the center of the cell.

- The cell nucleus divides only once

- Two diploid daughter cells form that are identical to the parent cell.

Explanation:

Mitosis and Meiosis are the two cellular divisions that occur in living organisms. Mitosis is the kind of cell division that produces two diploid daughter cells that are genetically identical to the parent cell while Meiosis produces four haploid daughter cells (gametes) that are genetically different from the parent cell.

Based on the general description of the two cell divisions above, the following events take place in them respectively:

1) MEIOSIS:

- Each replicated chromosome pairs with its corresponding homologous chromosome (similar but non-identical chromosome from each parent).

- Tetrads form and crossing over sometimes occur. Tetrads are the structures that form when two homologous chromosomes pair while crossing over is the exchange of chromosome segment between two non-sister chromatids of homologous chromosomes. These two only occur during meiosis.

- Paired homologous chromosome line up across the center of the cell during metaphase I of meiosis.

- Four haploid daughter cells form that are not identical to the parent cell. Note that meiosis reduces the chromosomal number of the parent cell by half.

2) MITOSIS:

- Homologous chromosomes do not pair during mitosis.

- One row of replicated chromosomes (sister chromatids) line up at the center of the cell during metaphase.

- The cell nucleus divides only once in mitosis as opposed to twice during meiosis.

- Two diploid daughter cells form that are identical to the parent cell. Note that mitosis retains the chromosomal number of the parent cell.

pentagon [3]

Answer:

1. charophytes

Explanation:

  • These are macrophytes that grow entire in the freshwater and become fossilized by the calcification oozes,  going back to the Paleozoic era about 250 million years ago.
  • And they are unicellular to multi-cellular organisms also found in moist terrestrial habitats.

Can someone give me 4 examples of physical weathering
valkas [14]
Yes, sure!

1) Moving Water - Water, when running for a long period of time, can actually start to weather rocks.

2) <span>Ice wedging - Yep, this can cause rocks to weather as well. Water, when being constantly frozen and unfrozen weathers the rock due to the fact that water is able to expand.
</span>
3) Plant Roots - Ah, these little nutrient grabbers can certainly weather rocks over periods of time.

4) Winds - Winds can certainly physically weather the rocks, and it's probably the most common way they do.


<span>P.S. If this answer helped you, please, make sure to say "Thanks" just below my answer. It will help me a lot</span>
