I'm pretty sure they are. Most large objects, like a log, (We are talking tree log here right?) will be composed of cells of some sort or another. Hope that helps:)

Yes logs are made up of cells, Plant cells to be exact.

2. Traditionally, protists were classified in kingdom Protista. How has the classification of protists changed? 3. Relate Cause
pantera1 [17]

Protists are the eukaryotes which are neither plants, animals nor fungi. But they are plant-like, fungi-like and animal-like organisms.  It is difficult to classify all the protists in one kingdom Protista because of their numerous diversified traits. There are a few parasites, predators and also producers among the protists. Some have a cell wall, while others have a cell membrane. Mode of locomotion can be flagella, cilia or the pseudopodia. The best example is the <em>Euglena</em> exhibiting both plant and animal like characteristics in having a chloroplast performing photosynthesis and exhibiting locomotion by flagella. These diversified traits made the scientists to reclassify the protists. The kingdoms which arose from protist ancestors include the kingdom animalia, plantae and mycota sharing common characteristic features with their ancestor. Scientists say that we should not look for the earliest ancestors of animals among modern-day protists because, the modern day protists have gone through a process of evolution which makes them different from their early ancestors. The gradual changes during the course of evolution has made them different from their ancestors with respect to their structure, adaptations and also the genetic composition.

Each orientation of chromosomes produces gametes with the same genetic information from each parent.
oksano4ka [1.4K]

Answer: a) true

Explanation:

The goal of mitosis is to produce daughter cells that are genetically identical to the mother cell, without a single extra or missing chromosome. Meiosis, on the other hand, is only used for one purpose in the human body: the production of gametes or sex cells, i.e. sperm and eggs. The question is oriented to mitosis, <u>in which prior to this cell division, the cell duplicates its DNA</u> so that each daughter cell then inherits the genetic material. That is, the cell originally possesses 23 chromosomes, they duplicate to a total of 46 so that then each daughter cell receives 23.

The metaphase is the second phase of mitosis and meiosis that occurs after prophase where the envelope is lost and microtubules of the achromatic spindle (also called meiotic or mitotic) appear.

During metaphase, the chromosomes align themselves in the middle of the cell and this balanced midline spindle alignment is due to the equal and opposing forces generated by the kinetochore brothers.

Then during metaphase, the chromosomes will line up in the center of the cell to be separated and go each to a different daughter cell. But the moment they're found there, each orientation of chromosomes produces gametes with the same genetic information from each parent. <u>Because because there have been no changes or mutations in the chromosomes, they have duplicated and have the same genetic information.</u>

Given an example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem
AveGali [126]

Answer:

In the absence of decomposers, soil, air, and water would not be replenished, and all the nutrients present would soon get exhausted. Hence, the cyclic process of life and death would be disrupted and life would come to an end.
