Answer:
The correct words for the three blanks are as follows:
1. Endoplasmic reticulum. 2. Golgi apparatus. 3. Facilitated diffusion.
Explanation:
During the translation stage of protein synthesis, signal sequences are either attached or excluded from a synthesized protein in order to indicate the right location it should be sent to. Proteins that possess signal sequences are usually sent to the endoplasmic reticulum, where they will be folded into their right shapes. From the endoplasmic reticulum the proteins are then transported into Golgi apparatus via membrane vesicles. In the Golgi apparatus, proteins undergo their final modifications before they are transported to their final destinations. The final destination of glucose carrier proteins is the plasma membrane, where they help glucose molecules to enter the cell via facilitated diffusion.
Answer:
Ants and aphids have a special relationship, mutualistic in nature
Explanation:
hey each benefit from one another; ants protect aphids and aphids feed ants. Aphids feed their farmer ants a sweet honeydew liquid in exchange for protection from predators.
Answer:
Transpiration:
Losing the water absorbed by the plant through its aerial parts in the form of water vapor to the atmosphere. Water is absorbed by roots from the soil and transported as a liquid to the leaves via the xylem to mesophyll cells, through intercellular spaces, and moving through substomatal space to the stoma. The leaves and aerial parts have small pores that allow water to moves as a vapor.
Advantages:
With the transpiration exchange of gases also takes place.
Excess amount of water removed from the plant body.
Absorbing water and distribution of water among plant body parts
Cooling the exposed aerial parts of the plant to the sun and warm winds.
The osmotic balance of the plant cell is regulated by the process of transpiration.
The logical sequence in order to loss of water due to transpiration is as follows:
xylem, mesophyll cells, intercellular spaces, substomatal space, stoma.
<u>Answer:</u>
Approximately, the oldest stromatolites are 3.6 billion years old on earth.
<u>Explanation:</u>
- Stromatolites is not only oldest earths fossil but conspiracy in that they are singular visual portal in deep time on earth.
- It is defined as laminated accumulation structure that is they stick up above sea floor .
- Stromatolite buildings includes oldest fossils which are 3.5 billions old when the earth were too unfriendly to support life.
- The study of fossil age, evolutionary, method of formation are known as paleontology.
- These specimens are considered as old fossils which are around 3.4 to 4.1 billions years old.
