Answer: This is because animals (like humans) have more organelles to store in our bodies than bacteria. This makes sense because without all of our organelles we wouldn't be able to function properly. This is just another one of those form=function things.

life cycles of sexually producing organisms involve the alternation of haploid and diploid stages true/false

kolbaska11 [484]

Answer:

True

Explanation:

The life cycles of sexually producing organisms generally involve alternation between the haploid and diploid generations.

Sexual reproduction involves the fusion of gametes - fertilization. The gametes are haploid (n) and are usually formed by the reductional division (meiosis) of diploid (2n) sex cells.

Haploid gametes represent the haploid stage of the life cycles of sexually reproducing organisms. During fertilization, the male and female gametes fuse together to form a diploid zygote. The zygote then continues to divide equationally (mitosis) and differentiates to give rise to a baby and eventually to either male or female adult organism.

Phoenix [80]

Answer:

seafloor

Explanation:

A plate, often described as a lithospheric plate, with seafloor, continents and mountains on top of it.
The earth is divided into three layers based on their chemical composition. Undoubtedly, there is a component called the lithosphere.
The lithosphere consists of a crust and a portion of a solid upper mantle.
Below the lithosphere is the asthenosphere.
There are two types of crusts: the continental crust and the oceanic crust.
Where there is a seabed there is a sea crust.
Mountains are also found in oceanic and continental crusts.
The intercontinental layer corresponds to the continents.
