Answer: Carbon monoxide

Explanation:

Carbon monoxide is a gas that is tasteless, colorless, and odorless, that is formed when wood, charcoal, gasoline is burnt.

When breathed in, carbon monoxide is harmful as it displaces the oxygen that is in the blood and this leads to the deprivation of the brain and other vital parts of the body of the oxygen that's is required for daily functioning.

Exposure to carbon monoxide is most likely affected cell differentiation in the growing embryo. When the pregnant woman inhales smoke, this affects the oxygen in the baby's bloodstream as it's being replaced by carbon monoxide and there's shortage of oxygen.

This affects the cell differentiation in the growing embryo and can lead to the child been born prematurely and can also lead to severe asthma like symptoms.

Which of the following molecular motors is associated with intermediate filaments?
azamat

Answer: d. none of the other answers

Explanation:

Enzymes that turn chemical energy into mechanical work are molecular motors.

There are three main components of cytoskeleton including microtubules, actin filaments and Intermediate filaments. Only actin  filaments and microtubules carry the motor-driven transport on the cytoskeleton.

The most important feature of intermediate filaments is to provide the plasma membrane with mechanical support where it comes into contact with the extracellular matrix and other cells.

Unlike microtubules and microfilament , intermediate filaments are not involved in motility of the cells, hence do not associat with molecular motors.

Hence, the correct option is d.

Why are sedimentary rocks the only ones to show fossils please help me!!!!!!!!!!!!!!
Gnoma [55]
They form under a pressure and heat that doesn't destroy the fossils. Igneous and metamorphic rock form from molten rocks thus reaching a temp that destroys the fossils within.

Which of the following statements comparing respiration in fish and in mammals is correct?
levacccp [35]

Answer: The following statements <em>comparing respiration in fish and in mammals</em> is correct:

  • The movement of the respiratory medium in mammals is bidirectional, but in fish it is unidirectional.

Explanation:

<u>Breathing </u>is the process by which living beings <em>exchange gases</em> with the external environment. It consists of the <u>entry of oxygen</u> into the body of a living being and the <u>exit of carbon dioxide</u> from it .

Active ventilation occurs if the animal produces the currents (of air or water) that flow to and from its respiratory membranes. It can be :

  • Unidirectional. (air or water is pumped onto the respiratory membrane in only one direction).
  • Bidirectional. (air or water is transported to the respiratory membrane and moves away from it through the same route like in the mammals).
