Kaleb has extensively resistant tuberculosis (tb). treatment for extensively resistant tb would include

klemol [59]

Extensively drug-resistant tuberculosis is a form of tuberculosis which is caused by bacteria that are resistant to some of the most effective anti-TB drugs such as isoniazid and rifampin. This form of tuberculosis occurs due to an individual’s mismanagement of multidrug-resistant TB. Treatment for extensively resistant TB would include medication with at least two drugs to which the TB is susceptible.

Determine whether each statement describes mitosis, melosis, or both mitosis and melosis.

Kruka [31]

Answer:

This question is incomplete as it lacks statements, the statements and the answers are as follows:

occurs in organisms that sexually reproduce - MEIOSIS

occurs during growth and development - MITOSIS

the DNA is replicated - MITOSIS AND MEIOSIS

occurs in all organisms - MITOSIS

the number of chromosomes remains the same - MITOSIS

the number of chromosomes reduces by half - MEIOSIS

Explanation:

Meiosis and mitosis are both types of cellular divisions that occur in living cells. Mitosis involves the formation of two (2) daughter cells that are genetically identical to the parent cell while meiosis involves the formation of four (4) daughter cells that are genetically different from the parent cell.

The following are characteristics of the two division processes based on this question:

MITOSIS:

- It occurs during growth and development of an organism.

- it involves DNA replication

- it occurs in all organisms since every living organism undergoes growth and development.

- the number of chromosomes after mitosis remains the same in the daughter cell i.e. 2n remains 2n

MEIOSIS:

- It occurs only in organisms that sexually reproduce.

- it also involves the replication of DNA

- The number of chromosomes in the daughter cells is reduced by half i.e. 2n to n.

Why do some small bridges have weight limits that depend on how many wheels or axles the crossing vehicle has?

Sladkaya [172]

Well you know sometimes you see a lot of small bridges that will have weight limit signs. I believe this is really for safety precautions. Keyword: SMALL bridge -

Due to some bridges being small, the materials and strength of the bridge may not can withstand a certain weight. The contents of the vehicle, axels, and wheels, all add to that weight. So there is a very good reason for that to matter.
I hope my somewhat, tied together answer provides just the information you need!

PLZ HELP!!!!

Karolina [17]

<h2><u>Answer:</u></h2><h3><u>Question 1:</u></h3>

The correct option is A (a curved path)

Explanation:

Their way is diverted by the revolution of the earth. This is the Coriolis impact. This is the motivation behind why wind streams on the northern side (north half of the globe) turn counter-clockwise and that blows south of the equator, the southern side of the equator, turn clockwise.

<h3><u>Question 2:</u></h3>

The correct option is B (forms at or near the ground)

Explanation:

Fog is an obvious vaporized comprising of modest water beads or ice precious stones suspended noticeable all around at or close to the Earth's surface.

Haze can be viewed as a sort of low-lying cloud, more often than not taking after stratus, and is vigorously impacted by adjacent waterways, geology, and wind conditions.
