1. What is the golgi apparatus?

Biology
1 answer:
Shalnov [3]4 years ago

1. The golgi apparatus is a membrane bound organelle found in most cells. It is responsible for packaging proteins into vesicles prior to secretion and therefore plays a key role in the secretory pathway.

3. A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.

5. A vacuole is a small cavity or space in the tissues of an organism containing air or fluid, or a cavity or vesicle in the cytoplasm of a cell usually containing fluid

6. Vacuole, in biology, a space within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid. Especially in protozoa, vacuoles are cytoplasmic organs (organelles), performing functions such as storage, ingestion, digestion, excretion, and expulsion of excess water.

7. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.

At rest, a cell membrane is said to be ___________.
max2010maxim [7]

Answer:

a. polarized

Explanation:

The whole living cell and in particular the nerve cells show electric potential difference between the inner and outer faces of their cell membrane.

The resting potential of a cell refers to the difference in electrical potential that the inner and outer faces in the membrane of a neuron that is not transmitting nerve impulses. The resting potential value is around -70mV (milliVolts). The negative sign indicates that the interior of the cell is negative relative to the exterior.

The existence of the resting potential is mainly due to the difference in concentration of sodium (Na +) and potassium (K +) ions inside and outside the cell. This difference is maintained by a mechanism of active ion pumping through cell membranes, in which sodium is forced out of the cell and potassium in.

At rest, the alternation between passive and active ion transport occurs. There is passive input of sodium (Na +) ions, which are subsequently actively expelled, while potassium (K +) ions enter actively. Then K + passes passively from the cell, making the external medium positive relative to the internal medium. With this, the cell becomes polarized.

Give five examples of gymnosperms and their geographical locations
nirvana33 [79]

Answer:

conifers, cycads, ginkgoes, Gnetophyte.

Explanation:

Gymnosperm (naked seeds). These type of plants don´t produce fruits nor flowers, the seeds are not contained within an ovary or fruit. The seeds are exposed on the surface of the leave-like structures named bracts, bracts are modified leafs or scales. The seeds of these type of plants are directly fertilized by pollination since they are open to the air.

Some examples are:

Conifers (cedars, douglas first, cypresses, etc), are distributed in most parts of the world, especially in cold areas. They are specially abundant in the boreal forest of the northern atmosphere.  

Cycads (genus Cycas, genus Bowenia, genius Dioon, etc) are natives of warm regions the Easter and Western hemisphere. They are well distributed in Africa, Australia, South America. They are prominent different species are found in Central America.

Ginkgo biloba (ginkgo) Is native from China.

Gnetophyte (Ephedra, Gnetum, Welwitschia mirabilis, etc) They are found in dry and cool regions in both hemispheres, western and eastern.

Ephedra is distributed in desert areas in the southwestern United States, and some parts in Mexico and South America.

Welwitschia mirabilis, is found in Namib desert of southwestern Africa.
