Stress granulesa. _________ The . . . has two concentric membranes, penetrated by pores to allow transport and making its internal space topologically equivalent to the cytosol.b. ___
Answer: option A - Nucleus
The Nucleus is a membrane-bound organelle. It has nuclear membrane, which consists of nuclear pores (made up of proteins) through which substances enter or leave the cell (RNA, proteins, etc)
Why is the kingdom protista considered the "junk drawer"kingdom? give at least two examples.
The kingdom that is protista is referred to as junk drawer because there are certain species which has no similar characteristics entirely to a particular kingdom. These species therefore are made an adjustment like a junk in the kingdom caller protista where a fungi, plant and many eukaryotic species gets to live.
What are eukaryotic organisms ?
Eukaryotic organisms are the organisms that are having the well defined organelles and their genetic material is not scattered.
Euglena is a species which is having a characteristics of both the plants and animals where the euglena is able to synthesise its food and on the other hand euglena is able to divide as well thus these characteristics make the species get an exemption from both the species.
On the other hand certain species as fungi are belonging to the kingdom of both plants and animals where the species get an exemption from following any kind of rules and regulations strictly belonging to one particular kind of kingdom.
These are Protists, they are considered the "Junk Drawer" because they arent Animals, Bacteria Plants, or Fungi.
They are Eukaryotes, and some examples are Forams, New Zealand Bull Kelp, and Sea Lettuce
One true-breeding line of mice is obese and dark and another is lean and light. Dark is dominant to light, but obese and lean exhibit incomplete dominance. What proportion of offspring from a dihybrid cross should be both dark and intermediate between obese and lean
6/16 Intermediate and dark ⇒ 2/16 OoDD + 4/16 OoDd
Due to technical problems, you will find the complete explanation in the attached files
The majority of the protein inside a red blood cell (erythrocyte) is:a. albumin b. hemoglobin c. fibrinogen d. immunoglobulin e. porphyrin
Explanation: Hemoglobin is a protein very rich in iron found in red blood cells and is responsible for the transportation of Oxygen from the lungs to the whole body. Oxygen binds to the hemoglobin in red blood cells and the red pigmentation of blood that is highly oxygenated is due to the hemoglobin content found in RBC's.
Passive expiration is preceded by the:a. recoil of the lungs b. contraction of the internal intercostals muscles. c. contraction of the diaphragm. d. increase in atmospheric pressure. e. increase in CO2 in the blood
The correct answer is option a. "recoil of the lungs".
Normal respiration is passive, which means that no energy is needed to release the air from the lungs. Passive respiration is preceded by the recoil of the lungs that happens without any effort because of the elasticity of the lungs tissue. After inspiration, the diaphragm and intercostal muscles relax and the thoracic cavity and lungs decrease in volume. This causes that the interpulmonary pressure rises above atmospheric pressure, creating an air pressure gradient that put the air out of the lungs without the need of energy.
Cells that do not have a true nucleus are called _____?
