Answer:

All proteins would be translated in the cytoplasm

Explanation:

The signal recognition particle (SRP) is a cytoplasmic RNA-protein (ribonucleoprotein) complex whose primary role is to target signal peptide‐bearing proteins to the plasma membrane in prokaryotes and to the endoplasmic reticulum in eukaryotes. In eukaryotic organisms, SRP binds to the signal sequence of the protein when the growing polypeptide chain emerges from the ribosome in the cytoplasm. This binding is key because it results in a slowing of translation, a mechanism known as elongation arrest. Therefore, without a functional SRP, elongation arrest would not occur and proteins would be translated on free ribosomes in the cytoplasm.

2. If a cell has a very large amount of ribosomes attached to its rough
Otrada [13]

Answer:

Protein

Explanation

Ribosome and Rough E.R are organelles  in the cell.

E.R are extensive membranes (which are continuous with the nuclear membrane) that exist as flattened compartment in the cytoplasm.These compartment form sacs in the cytoplasm. The sacs are interconnected with one another to form a complete system  called the reticulum.

Based on structure two types of E.R exists -the Smooth E.R and the Rough Endoplasmic reticulum.The later is called rough because of Ribosomes attached to its outer membrane. the smooth lacks ribosomes attachment on its outer membrane. Ribosomes are the site of Protein synthesis in the cell.

They are small in number and are made up of RNA and protein.Generally the protein  synthesised  in the Ribosomes,are moved into the sacs in the R.E.R,where they are modified.They are eventually budded off in vesicles which form the Golgi bodies

What is evidence that each color of visible light has a wave of a specific wavelength. pls help me :)
aliina [53]

Answer:

Dispersion of white light by a prism

Explanation:

When white light is passed through a prism, the white light separates into its component wavelengths which are:

Red

Orange

Yellow

Green

Blue

Indigo

Violet

Together, all of these wavelengths constitute the spectrum of white light.

Hence, the dispersion of white light shows that each color of visible light has a specific wavelength.

Explanation:

To preserve Zoological garden expertise are needed to manage the creatures that are there.

Good and conducive environment should be provided for the animals.

Routine cleaning to avoid outback of diseases

Adequate resources should be provided this include food to avoid eviction of important species.

Geosphere is made up of the crust they form the layer of soil that support growth of plant and also supply nutrients.

Atmosphere is made of gas some of which help sustain life. Example is oxygen, carbon dioxide

Hydrosphere form the liquid portion of the earth it included large water bodies that serves as habitat for aquatic organism.

Oxygen and carbon are been released into the atmosphere where they are been taking up by plant or animal dead and remains of this organism lead to the release of this gases in both organic and in organic form back into the soil where it is taken up by plants back into the atmosphere and some are washed in the water bodies.

Plants takes in carbon-dioxide from atmosphere, absorbs nutrients from the soil through their root and water from the water table needed fro their growth.
