Which atom woukd tend to lose one valence electron to another atom to become stable

2 answers:

8 0

An atom/electron (forgot which one) needs to have 8 atoms/electrons to become stable, hope I helped even tho I didn’t really understand the question

If you are saying losing an electron, so yes every atom needs to be in octate stage(8 electron) in outermost shell and if any atom have one extra electron than it loses electron gains positive charge and became stable by completing octet or duplet. They are found in first column of periodic table.

Examples - Na(sodium)

Flatworms use a system of canals and tubes with the ______ as their excretory organ.

Kazeer [188]

<span>Flatworms use a system of canals and tubes with the mouth as their excretory organ. They belong to the Phylum Platyheminthes. </span><span>Flatworms can be cut in half creating two individuals by binary fission. Binary fission is a type of asexual reproduction in which the offspring has the same features and characteristics of the parent. During binary fission, the DNA replicates into two and goes at the end of each membrane. And then the cell membrane divides into two daughter cells. Then cytokinesis follow.</span>

White blood cells are an important component of our immune system. One thing they do is consume and destroy bacteria by extendin

hammer [34]

Answer: Phagocytosis

Explanation: this is one of the various ways in which the immune system fights against bacteria and other pathogenic organisms. It does this by extending its plasma membrane outwards forming a structure like a pseudopodia which it utilises to engulf the invading organism.

I Using the key choices, identify the cell type(s) or blood elements that fit the following descriptions. Insert the correct ter

gregori [183]

Answer:

Neutrophil
Neutrophil
Eosinophil
Basophil
Red blood cell
Monocyte
Neutrophil
Monocyte
Lymphocyte
Megakaryocyte
Formed elements
Eosinophil
Basophil
Lymphocyte
Red blood cell
Plasma
Monocyte
Basophil

Explanation:

A. Red blood cell: Blood cell that is a product of the medulla. These cells contain hemoglobin that carries oxygen from the lungs to the rest of the body.

B. Megakaryocyte: Big cell easy to recognize for its size. Differs from other cells for being polyploid, growing by endomitosis, and being bigger. They have important biological functions. The most important one is the formation of plaquettes, necessary for hemostasia, damaged vessels reparation, and tissue healing.

C. Eosinophil: Granulosites. Immune System cells, active during infections, pathologies, inflammations, and allergies. Originated in the medulla and transported to the blood and organs. One of their functions is to defend the organisms from parasite infections, helping to destroy the pathogen.

D. Basophil: Granulosites. Immune System cells. in the medulla and transported to the blood. Only when there are parasite infections they can be present in tissues and organs. They release substances such as histamine that make possible the inflammatory process.

E. Monocyte: Agranulocyte phagocyte. Originated in the medulla and transported to the rest of the body. They differentiate into macrophages in tissues. They defend the body from bacteria and viruses. When monocyte values are elevated, usually means that there is an important process of infection.

F. Neutrophil: Phagocytic Leucocytes polymorphonuclear found in the peripheric blood. Compose the first defense line against bacterial and fungal infections. Product of the medulla and transported to the blood. They are the first to arrive at the affected tissue, followed by lymphocytes and macrophages.

G. Lymphocyte: Leucocyte. There are two types of lymphocytes: B cells, which can produce antibodies in the presence of bacteria, viruses, and toxins. T cells can destroy infected cells from the body. They all circulate in the blood.

H. Formed elements: Elements that might be found suspended in the plasma. These include all the mentioned cells and cell fragments

I. Plasma: Transparent, acellular, and kind of yellow liquid that represents 55% of the blood volume.

If LAL (limulus amebocyte lysate) turns into a gel when exposed to a sample, it

Vlad1618 [11]

Answer: The statement is TRUE.

Explanation:

Gram negative bacteria is a type of bacteria that possesses, from the interior to the exterior, a cytoplasmic membrane, a thin peptidoglycan layer, and an outer membrane containing lipopolysaccharide. The lipid portion of the lipopolysaccharide complex of the outer layer acts as an ENDOTOXIN.

The endotoxin of the gram negative bacteria can be detected in research or biomedical laboratories through a technique called LIMULUS AMEBOCYTE LYSATE test.

The test procedure follows a principle that the endotoxin of these gram negative bacteria are capable of forming gel clots (coagulation) of blood cell (amoebocytes) lysates of the Limulus polyphemus crab.

Therefore, If LAL (limulus amebocyte lysate) turns into a gel when exposed to a sample, it

means the sample is contaminated with endotoxins of gram-negative bacteria.
