Answer:
- Based on this information you come to the conclusion that you have been able to identify in these cells the structure of <em>microfilaments</em> or <em>actin filaments</em>.
- <em>Oviductus oblatus</em> are indeed eukaryotic cells
Explanation:
In eukaryotic cells, the cytoskeleton is composed of three well defined filamentous structures: microtubules, microfilaments, and intermediate filaments. Each of these filamentous structures is a <u>polymer of proteinic subunits</u> united by weak, not covalent connections.
The microfilaments are the thinnest of the three structures. They have a <u>diameter of 7 nanometers</u> and are <u>composed of many proteinic monomers</u> united. This monomeric protein is called actin. Many monomers get combined to form a structure that assembles a double helix.
Due to the fact that these microfilaments are made of actin monomers, they are also known as actin filaments.
Actin filaments have directionality which means that their extremes have different structures.
In eukaryotic cells, genes that codify for actin microfilaments are highly conserved in all organisms, which is why <u>they are often used as molecular markers</u> for different studies.
No, you cannot.
25% of 1600 is 400
1600-400=1200

The correct option is (C) The neuron’s membrane voltage becomes more positive.
The resting neuron has a voltage across its membrane which is called the resting membrane potential. There is a concentration gradient of ions across the membrane when the neuron is in the resting state.
Inside the membrane the concentration of K⁺ and organic anions are more. Outside the membrane the concentration of Na⁺ is more. The membrane is much more permeable to K⁺ than Na⁺ .
The cell’s inside is more negative than the outside when the membrane is hyperpolarized. In neurons the resting membrane potential is close to the equilibrium potential for K⁺.

Answer:
In short, raw material extraction and processing always impact on the environment, resulting as they do in soil degradation, water shortages, biodiversity loss, damage to ecosystem functions and global warming exacerbation
Explanation:
Production is the creation, consumption is the use or destruction of resources and fuels
