Answer : The correct answer is -

A-meiosis.

Meiosis is a type of cell division (a reductional cell division) that occurs during the process of formation of gametes particularly in sexually reproducing organisms.

During prophase of meiosis I, crossing over between homologous chromosomes takes place, resulting in the genetic diversity in new chromosome that come in the gametes.

Apart from this, when gametes from two parents fuse, new genetic combination is produced in the resulting zygote.

Thus, meiosis is a source of genetic variation in case of sexually reproducing organisms.

Clinical indications for the use of adrenergic drugs stem mainly from their effects on the heart, blood vessels, and bronchi. Th
uranmaximum [27]

Answer: Adrenergic drugs are used both in the emergency treatment of Myocardial infarction, Asthma attack and Anaphylaxis T/F.

Explanation:

Andrenergic drugs acts by blocking renin release,and interfers with synthesis and release of Nor-epinephrine (Nor-adrenaline) thereby helping to reduce the peripheral vascular resistance and lowering the blood pressure.example; Methyldopa.

As a bronchodilator in asthma attack, Adrenergic drugs relax bronchial muscle spasm then dilate the bronchial trees thereby allowing proper ventilation of the lungs example: Aminophylline

Adrenergic drugs like epinephrine are used in anaphylaxis/ allergic reactions as well as hypersensitivity reactions to inhibit the action of histamines and as such relieve allergic reactions.

Match each atom to the corresponding number of electrons it will steal or give away.
Stella [2.4K]

Answer:

1. Fluorine (7 electrons) => c. steals 1 electron

2. Calcium (2 electrons) => a. gives away 2 electrons

3. Oxygen (6 electrons) => d. steals 2 electrons

4. Lithium (1 electron) => e. gives away 1 electron

5. Xenon (8 electrons) => b. neither gives away nor steals any electron

Explanation:

Given the following valence electrons of the atoms listed above, each atom can be matched to its corresponding number of electrons it can steal or give away as they form bonds and attain a stable state:

1. Fluorine (7 electrons) => this will steal 1 electron from another atom to attain a stable state when it comes to make the number of electrons 8.

2. Calcium with 2 valence electrons, will give away this 2 electrons in its outer shell to be stable and form bond with another atom that will accept these 2 electrons.

3. Oxygen with 2 valence electrons, will steal 2 electrons to make the electrons in its outer shell 8, as it bonds with another atom to become stable.

4. Lithium will give away 1 electron to become stable when it combines.

5. Xenon with 8 electrons in its outer shell is in a stable state and kind of inert. It doesn't need to receive or steal any electron from or to any other atom in this state.
