aalyn [17]

Answer:

1)Genus 2)Family 3)Order 4)Phylum 5) Domain

Explanation:

Species is a large group of living organisms that can breed freely among themselves, exchange genes and produce offspring.

Taxonomic rank is the group of living organisms that are related to each other and most basic rank is species. The lower the rank the smaller it be and contain most similar organisms.

The higher rank comprises by combining of smaller ranks like in your question the family contain many genus and order contain many families and so on. Thatswhy most higher rank would contain maximum number of species.

Determine how to make positive and negative ions. Based on your exploration which subatomic particle is positive? Which subatomi
Katena32 [7]

Answer:

Atoms are electrically neutral as a result of having an equal amount of positive (due to the protons) and negative (due to the electrons) charges on it.

An ion generally is an electrically unbalanced atom (i.e an atom with a net charge on it)

A negative ion called an anion is produced when an atom gains an extra electron from a neighboring atom, giving it an extra negative charge. This can be produced by ionization with a radioactive radiation or simply by dissolution.

A positive ion is called a cation and it is produced when an atom loses electron to a neighboring atom. The loss of this electron causes the positive charges to outweigh the negative charges in the atom. Cations can be produced by radioactive radiation ionization of an atom or by simple dissolution.

The subatomic particle that is negative is the 'electron'.

nalin [4]

Answer:

The use of the word "draw" here refers to the collection of blood samples for laboratory tests.

Step A - The first draw goes into the blood culture bottle or tube with a yellow cover.

Step B - This goes into the coagulation tube with a blue cover.

Step C - The next draw goes into the tube for non-additives. This usually has a red top

Step D - This features collection of blood into the tubes with additives. When dealing with additives, blood samples and additives it is important that the sample and additive is rigorously homogenized. This part can is broken down as follows:

  1. this goes into the SST tube. This tube contains a seperator and a clot activator and is usually is colour coded reddish-gray or gold top.
  2. This tube contains Sodium heparin and has a leaf green top
  3. This tube (PST) contains PST contains lithium heparin anticoagulant and a gel separator.  It's cover is colour coded light green
  4. This tube contains Ethylenediaminetetraacetic acid or EDTA for short. It's cover is usually colour coded lavendar
  5. This tube is labelled ACD that is Acid Citrate Dextrose. It's top is coded light yellow
  6. this tube contains Oxalate/Fluoride and it's cover must be colour coded gray.

Photosyntheis and resperationMove to Bottom Carbon dioxide is a product.A. Carbon dioxide is a reactant.B. Carried out in animal
EleoNora [17]

Answer:

The correct answer is-

1. Photosynthesis- Carbon dioxide is a reactant, Oxygen is a product,  Carried out in plants, Produces usable energy source.

2. Respiration- Carbon dioxide is a product, Oxygen is reactant, Carried out in animals, Produces usable energy source.

Explanation:

Photosynthesis is a complex process which takes place in the green plants which synthesize the energy molecule called glucose. The reaction takes place in the presence of sunlight combining the carbon dioxide and water forming the glucose and oxygen gas.

Respiration is a complex process which involves the breakdown of the glucose molecule in the presence of oxygen and forming the energy molecule called ATP which is utilized in the metabolic reactions. The complex process releases carbon dioxide.
