Answer:

Red blood cell is a blood cell which contains hemoglobin necessary for the transport of oxygen in blood from one part of body to another part.

Explanation:

These are the most abundant cells in the blood and are developed from liver and yolk sac in fetus while from the bone marrow in children and adults. Red blood cells (RBCs), also called erythrocytes, are cells that circulate in the blood and carry oxygen throughout the body. These cells are produced in the bone marrow and are released into the bloodstream as they mature. RBCs typically make up about 40% of the blood volume. The normal RBC range for men is 4.7 to 6.1 million cells per microliter (mcL). The normal RBC range for women who aren't pregnant is 4.2 to 5.4 million mcL. The normal RBC range for children is 4.0 to 5.5 million mc.

How abundant are plankton?
lara [203]

Answer:

While plankton are most abundant in surface waters, they live throughout the water column.

Explanation:

Plankton inhabit oceans, seas, lakes, ponds. Local abundance varies horizontally, vertically and seasonally. The primary cause of this variability is the availability of light. All plankton ecosystems are driven by the input of solar energy (but see chemosynthesis), confining primary production to surface waters, and to geographical regions and seasons having abundant light.

Which data would not affect maximum likelihood estimates of phylogenies when comparing different tree hypotheses?.
Leona [35]

The set of species derived from one common ancestor.

To build phylogenetic trees, a variety of data can be employed, including genetic information, mitochondrial DNA sequences, ribosomal RNA genes, and any relevant genes, as well as morphological information such as structural characteristics, organ kinds, and specific skeletal arrangements

<h3>What is a Phylogenetic tree ?</h3>

A phylogenetic tree, also called a phylogeny, is a diagram that shows the evolutionary branches from which various species, creatures, or genes have descended from one another.

  • A phylogenetic tree can be used to track a species' evolutionary history back via the tree's branches and find their common ancestors along the way.

  • A lineage may preserve some of its ancestors' characteristics over time, but it will also change over time to accommodate the environment.

Which source should be avoided when conducting scientific research?
Dennis_Churaev [7]
When we're doing scientific research, we should definitely be avoiding any sources which aren't scientific by nature. This means we should avoid sources which haven't been peer reviewed by fellow authors of a similar field. With this, we avoid using literature of questionable quality.
