What is created from mitosis in animals?
lapo4ka [179]
A. two identical nuclei
<span>Mitosis, simply put, is the division of the nucleus of a cell. It is the phase in the cycle of a cell in which the two chromosomes in a cell divide and separate in a nucleus of their own. These chromosomes are completely identical. As a result of mitosis, two identical cells are formed and are known as daughter cells. This process copies and transfers DNA into both the cells that are formed as a result of Mitosis.</span>

Which statement below describes a feature that is shared between kinesin and dynein? a. Both proteins "walk" towards the (+) end
spin [16.1K]

Answer:

C)Both proteins bind ATP and F-actin

*C option is not mentioned* there is a flaw in the question

Explanation:

Two families of motor proteins, kinesin and dynein, transport membrane-bounded vesicles, proteins, and organelles along microtubules. Nearly all kinesins move cargo toward the (+) end of microtubules (anterograde transport), whereas dyneins transport cargo toward the (−) end (retrograde transport).While

both the protiens have globular ATP-binding heads that function as the motor domain and interact with the microtubules.

Which of the following is an autotroph? a. mushroom b. tree c. deer d. wolf
aliina [53]

The right answer is b. Tree.

Some plants (like trees) have evolved with different unusual nutritional adaptations over time. Heterotrophic plants are plants that use only or partly a source of organic carbon to grow, unlike the most common autotrophic plants, which use inorganic carbon and water to grow, often through the process of photosynthesis (photoautotrophic).
