Answers

Answer 1

Answer:

The kingdom Archaebacteria is distinguished from the kingdom Eubacteria by the cell wall structure.

What is kingdom Archaebacteria?

The kingdom Archaebacteria represent the oldest class o living thing and the most primitive also. They are known to survive under very harsh conditions hence they existed in primordial times.

The characteristic that serves to distinguish the kingdom Archaebacteria from the kingdom Eubacteria is the cell wall structure.

Where should the biosphere label appear in the system model? Use reasoning to explain your answer.

Answers

Answer:

Biosphere is the one of the sphere of geological sphere of the earth such as geosphere, hydrosphere and atmosphere. It is deal with the interaction and existence of the living organisms.

In this model it can be seen that there are human, fishes, and vegetation of plants are living organisms so living organisms in the hydrosphere (fishes), geosphere (plants) and anthrosphere (human) should be label as biosphere instead of atmosphere or with atmosphere.

The biosphere label should be appeared in the system model that contains geological sphere of the earth.

What is biosphere?

It is the one of the sphere that comprise of the geological sphere of the earth like the geosphere, hydrosphere and atmosphere. In this, there should be the existance and the interaction of the living organism.

Here in the given model, there should be the human, fished, etc should be labeled as the biosphere rather than the atmosphere or without the atmosphere.

A root is absorbing water from the soil. Which route will the water travel inside the root? A. Cambium --> phloem --> xylem --> stele --> endodermis --> cortex --> epidermis/// B. Xylem --> phloem --> endodermis --> stele --> epidermis --> cortex --> cambium ///C. Epidermis --> cortex --> endodermis --> stele --> xylem --> phloem --> cambium

Answers

The router through which water will travel inside the root is Xylem --> phloem --> endodermis --> stele --> epidermis --> cortex --> cambium. The correct option among all the options that are given in the question is the second option or option "B". I hope that this is the answer you were looking for and it has helped you.

Answer:

Option B, Xylem --> phloem --> endodermis --> stele --> epidermis --> cortex --> cambium ///

Explanation:

The start of water transportation via roots takes place through the Xylem as these are the specialized cell in roots to intake water from the ground. These cells are arranged in the form of layer and filters the water before transporting. After the filtration in Xylem, water then passes to phloem (which are also part of conducting system of plants and runs parallel to the xylem). After the phloem, water then goes to the central part of the root which is known as stele and then it reaches the epidermis. From epidermis , absorbed water then goes to the cortex of other tissues and organ and finally it reaches the cambium.

Hence, option B is correct

Sodium has one electron in its outer energy level. According to the octet rule, _____.

Answers

A sodium atom has a single electron in its outermost electron shell, the first and second shells again being full with two and eight electrons respectively. To remove this outer electron requires only the first ionization energy, which is +495.8 kJ per mole of sodium atoms, a small amount of energy. By contrast, the second electron resides in the deeper second electron shell, and the second ionization energy required for its removal is much larger: +4562.4 kJ per mole. Thus sodium will, in most cases, form a compound in which it has lost a single electron and have a full outer shell of eight electrons, or octet.

Answer : According to the octet rule, sodium wants to lose an electron.

Explanation :

The given element is sodium with atomic number 11 that means it has 11 electrons.

The electronic configuration of sodium will be,

$1s^22s^22p^63s^1$

From the electronic configuration, we see that one electron of sodium present in its outer energy level. Sodium can be lose one electron easily for the stable electronic configuration.

According to the octet rule, sodium has the tendency to lose one electron and form positive ion with the charge (+1).

Hence, according to the octet rule, sodium wants to lose an electron.
