The bark of a tree trunk includes which of the following tissues?

The subatomic particles/units that govern potential chemical reactions among elements are?

kow [346]

The subatomic particles or units inside the cell that is responsible for the potential chemical reactions among chemical species are the electrons. Since they are found outside the nucleus, it is actually easier for them to transfer from one atom to the other. They may be also shared between two compound.

Which of the following statements best describes a benefit of sexual reproduction?

Ivan

Among the listed options, we can conclude that option C which states that "It results in the diversity of the species that enhances the probability of survival." is correct.

Sexual reproduction offers organisms an advantage over those who undergo Asexual reproduction. Though there are benefits and drawbacks to each method, Sexual reproduction is a method that is better adapted to a changing environment and promotes the faster evolution of a species.

The main benefit of sexual reproduction is that it allows for a greater diversity of the species which enhances the probability of survival. This is due to the fact that sexual reproduction leads to varying combinations of alleles for specific traits, which coupled with selective reproduction (the ability of a member of the species to choose a spouse with desirable traits) leads to offspring who over time are increasingly better adapted to life in the given environment, with specific traits tailored for survival.

The mitotic spindle consists of two types of microtubules: kinetochore microtubules and nonkinetochore microtubules. In animal c

Blababa [14]

Answer:

The correct answer will be

1. Lengthen

2. Lengthen, shortens

3. Disassemble

Explanation:

There are three types of microtubules present during cell division: kinetochore, aster and polar microtubules.

1. During prophase: all types of microtubules grow out at their positive(+) ends which functions to pull and push the sister chromatids apart towards opposite poles so they lengthen.

2. During anaphase : non-kinetochore microtubules- polar microtubules polymerization takes place at their (+) ends which causes the spindle fibres to move apart while kinetochore microtubules which have been attached to the kinetochores of chromosomes shorten at their (+) ends and motor proteins travel to (-) end because of which sister chromatids move towards the spindle poles.

3. During telophase: non-kinetochore microtubules depolymerize or disassembles.

Thus, 1. Lengthen, 2. Lengthen, shortens and 3. Disassemble are the correct options.
