Fossils can be formed in the mud because
luda_lava [24]
Well, when a plant or animal dies in a damp environment it will most likely get buried in mud or silt. The tissues over time will decompose and leave bones or shells behind ( depending on what was there originally it can vary) Eventually over time sediment builds up and hardens into rock.
I sincerely hope this helps you ~

All of the following contributes to turbulent blood flow except A) when there are irregularities in the vessel wall. B) at high
GaryK [48]

All of the following contributes to turbulent blood flow except  third and fourth heart sounds.

<h3><u>Explanation:</u></h3>

The blood flow in human body is always described to be laminar. Some conditions cause the high flow when there is an ascending aorta. This causes the laminar flow of blood into turbulent. When this occurs the flow of the blood will not be smooth and linear.  

When the kinetic energy in the fluid flow increases the turbulent flow of blood occurs. Both the magnitude and the direction of the flow changes in this type of blood flow. These are caused by the irregularities in the vessel walls, flow rates to ne higher and opening of the valves of the heart.

The light micrograph shows dividing cells near the tip of an onion root. Identify a cell in each of the following stages: propha
ad-work [718]

Mitotic division in onion root cells:

  1. Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
  2. Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
  3. Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
  4. Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.

Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.

A researcher wants to introduce the human gene encoding tissue plasminogen activator (used to dissolve blood clots) into a mamma
Dmitrij [34]

Answer:

In the given case, for the researcher to succeed, there is a need to place the gene next to the promoter sequence, which gets expressed in the mammary cells. The sequences of DNA, which illustrate that where the transcription of a gene by the RNA polymerase initiates is known as the promoter. These sequences are generally situated at the 5 prime terminals of the initiation site of transcription or are situated directly upstream.
