c) ribosomes on the rough endoplasmic reticulum; Golgi apparatus

d) mitochondrial ribosomes; smooth endoplasmic reticulum

e) cytoplasmic ribosomes; plasma membrane

Answers

Answer:

c) Ribosomes on the rough endoplasmic reticulum; Golgi apparatus

Explanation:

Endoplasmic reticulum, a member of endomembrane system. If it contains ribosomes on their surface, they are called Rough Endoplasmic Reticulum (RER). RER is the site for protein synthesis.

Newly formed protein undergoes modification, one such modification is the addition of carbohydrate side chains to form glycoprotein. The protein then moves to the Golgi for modification.

Bones act as a frame to which _____ are attached for movement.cartilage
organs
striated muscles
cardiac muscles

Answers

The three types of muscular tissue are skeletal, smooth and cardiac. Skeletal muscles are muscles which are attached to the bone. Their main function is to help with skeletal movements. The smooth muscles are also known as involuntary muscles. We are unable to control their movements. It is found in the walls of organs such as the stomach and the bronchi. Lastly, the cardiac muscle is the heart muscle. It is only found in the walls of the heart. Structurally, it is a combination of the skeletal muscle type as well as the smooth muscle type

i know this is late but the correct answer is the cardiac muscles

Which is the result of telophase 1 and cytokinesis

Answers

Answer:

The result of Telophase 1 and Cytokinesis is two haploid daughter cells that are genetically different from the original cell.

Explanation:

Telophase I. At each pole, during this stage, there is a complete haploid set of chromosomes (but each chromosome still has two sister chromatids). A cleavage furrow appears, and by the end of this stage the parent cell has divided into two daughter cells. This separation of the cytoplasm is called cytokinesis.
