Answer:

osmosis is the correct answer

Explanation:

BC it doesn't make energy.

I’m not positive but: having 2 nutrients on one side of the membrane, and 6 on the other side. 2 of the 6 cross over to make 4 and 4. It’s not using energy since it’s going with the concentration, so it’s passive transport.

Classify each cell as haploid or diploid. 1. microspore:
Alex17521 [72]

Answer:

microspore: haploid

2. first polar body: haploid

3. spermatid: haploid

4. ovum: haploid

5. secondary oocyte: haploid

6. primary spermatocyte: diploid

7. microsporocyte: diploid

8. oogonium: diploid

9. megaspore: haploid

10. spermatogonium: diploid

Your answer

Explanation:

1. Microspore is a haploid spore produced by mostly ferns. They give rise to male gametophytes, which in turn produces sperm cell.

2. Polar body is one of the haploid cells that forms during the process of oogenesis (gametogenesis), specifically when the primary oocyte undergoes an unequal division.

3. A spermatid is an haploid cell that arises from the second meiotic division of the spermatogonia.

4. The ovum is the female gamete of most sexual reproducing organisms. It is also called the EGG CELL. It is haploid.

5. Secondary oocyte are haploid cells that results from the meiotic division of the primary oocyte.

6. Primary oocyte is the diploid cell that starts the meiotic division during oogenesis. It arises from the mitotic division of the oogonium.

7. The microsporocyte is the diploid cell that undergoes meiotic division to produce microspores in ferns and other land plants.

8. Oogonium are the diploid stem cells that initially starts the oogenesis process. It undergoes mitosis to form the primary oocyte, which divides meiotically till the ovum is formed.

9. Megaspore is a haploid spore that gives rise/germinates to the female gametophyte in ferns. The female gametophyte produces the haploid eggs.

10. Spermatogonium are undifferentiated stem cells that produces the sperm cells in males via the process of spermatogenesis. The spermatogonia is diploid in nature

Which statements describe transform boundaries? Select two options,
Elan Coil [88]

The given question is incomplete. The complete question is:

Which statements describe transform boundaries? Select two options.

Rift valleys are formed.

Mountains are created.

Faults form in the lithosphere.

Plates move toward each other.

Plates slide in opposite directlồns.

Answer:

The correct options are that formation of faults takes place in the lithosphere and the sliding of the plates takes place in the opposite direction.

Explanation:

The transform boundaries signify towards the site where sliding of the plates takes place past each other, it is also called transform plate boundaries. In the process of the formation of the transform boundaries, neither the formation nor the destruction of the lithosphere takes place, however, in the process formation of thin rift valleys occurs.  

The majority of the formation of the transform boundaries are witnessed on the floor of the sea. These boundaries possess the tendency of giving rise to earthquakes of high intensity that imparts a deleterious influence on the ecosystem. California's San Andrea is an illustration of transform boundaries.

1. In a soil ecosystem, matter _________________ and energy ___________________.
Aliun [14]

Answer:

Recycled, not recycled

Explanation:

In a soil ecosystem, matter is recycled and energy isn't recycled.

Matter is recycled through biogeochemical cycles. Matter has to be recycled because it can neither be created, nor destroyed, and as such, recycling is the only option left.

Energy isn't recycled because most of the energy gotten is used by organisms, as gotten from the plants already, and thus, when it gets to the food chain there isn't much left to be recycled.
