solong [7]4 years ago

An atom that gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion. Some atoms lose electrons and become positive ions. Others gain electrons and become negative ions.

<h2>Answer: </h2>

An atom becomes a positive ion by losing one or more of its electrons. Positively charged ions are called cations.

Positively charged ions are called cations. Generally, metallic elements turn into positive ions due to the quantity of valence electrons they contain. Metallic ions can achieve a full valence shell if they lose their outer electron(s). When they lose these electrons, the inner shell is now their valence shell, and it's complete. When this happens, they will have more protons than electrons, giving the atom a positive charge.

If a phospholipid is located in the outer layer of the bilayer in a vesicle, where will it end up when the vesicle fuses with th
Leviafan [203]

If a phospholipid is located in the outer layer of the bilayer in a vesicle, it will end up in the cytosolic face of the bilayer when the vesicle fuses with the plasma membrane.

The lipids on the exterior of a vesicle will end up in the phospholipid layer on the interior (cytosolic face) of the plasma membrane when it fuses with the membrane. The extracellular fluid in the plasma membrane will be in contact with the lipids on the interior of the vesicle membrane.

What is a phospholipid?

Phospholipids are a subclass of lipids that have two hydrophobic "tails" made of fatty acids connected by an alcohol residue. Their hydrophilic "head" contains a phosphate group (usually a glycerol molecule).

What type of evidence would you look for in a natural setting to indicate that there is competition taking placle among the plan
alexdok [17]

In a study, competition among plants are normal. Hence, all plants required a few basic elements like the light, water, nitrogen, or phosphorus, depending upon the species and the location. Evidence that can conclude that competition do really happen in plants is that some plants release toxins into the soil, in their dropped leaves which wipe out the competition for soil nutrients (such as weeds). And when it come an area with many trees in close proximity such as a forest, height is also indicative of competition for light.

Active and passive immunity involves all of the following except receiving mother's antibodies through breast-feeding. exposure
Bingel [31]

Explanation:

Immunity is the ability of an animal to resist infection.

There are two types of immunity in the body; INNATE OR INHERITED IMMUNITY AND ACQUIRED IMMUNITY. Inherited immunity it is the type of immunity that one is born with. It is passed from parent to offspring.

Acquired immunity is immunity to particular infections that is not inherited but has developed in the animal's life as it interacts with its environment. Acquired immunity can develop naturally in which case it is called NATURAL ACQUIRED IMMUNITY OR ARTIFICALLY.  

ACTIVE IMMUNITY is the form of acquired immunity in which the body produces its OWN antibodies against infections. While PASSIVE IMMUNITY is the form of acquired immunity in which an individual is PROTECTED AGAINST INFECTION BY RECEIVING ANTIBODIES.  

NATURAL ACQUIRED IMMUNITY

when attacked by the same pathogens again, they don't became seriously ill. this is because memory cells are able to recognise the antigens and stimulate the immune system to produce antibodies against the pathogens. This is known as NATURAL ACTIVE ACQUIRED IMMUNITY. It develops when one recovers from an infection.

During pregnancy, the mother passes antibodies across the placenta to the foetus. At birth the baby gets antibodies from the mother through breast milk. This is natural passive acquired immunity.
