The p wave on an electrocardiogram (ecg) represents the depolarization of cells in the sinoatrial (SA) node.

The sinoatrial node is close to the opening of the superior vena cava. This bundle of nerve tissue propagates electrical impulses and therefore governs sinus rhythm from minute to minute.

Electrocardiogram is a test, it is possible to detect the rhythm of the heart and the number of beats per minute.

Translocation can be investigated by using the ringing experiment, while peeling and removing the bark and phloem of a plant.

Translocation can be defined as a biological process which involves the transfer (movement) of water and other soluble nutrients from one part of a plant to another, especially through the xylem and phloem.

Generally, translocation can be investigated by using the ringing experiment, while peeling and removing the bark and phloem of a plant. Also, if sucrose is present, it would cause a swell and thus indicating translocation.

Explanation:

1 chemical reaction endothermic

2 physical change. exothermic

3 chemical reaction endothermic

Answer:

1. Chemical reaction   |    Endothermic

2. Physical change     |    Exothermic

3. Chemical reaction  |     Endothermic

Explanation:

• Chemical reaction or Physical change?

A chemical reaction occurs when one or more substances converted into one or more different substances; they are usually irreversible.

A physical change occurs when the state of matter, or any other physical property, of a substance changes; they are usually reversible.

• Endothermic or Exothermic?

An endothermic reaction or change is one in which the system takes in thermal energy.

An exothermic change is where thermal energy is given out by the system.

M. J. Schleiden:

In the year 1838, a German botanist presented the first cell theory (Although his theory was ultimately disproved, it did contribute to a change in scientific focus to cellular processes.)

All living creatures and body tissues are made up of the smallest unit that can live on its own. The cell membrane, nucleus, and cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates the molecules that enter and exit it.

His theory: Cells make up all plant tissues, and an embryonic plant is made up of just one cell. He declared that the cell is the fundamental building block of all plant matter.

Louis Pasteur- 1855 - German physiologist, physician, pathologist; and anthropologist. Added a third to the cell theory: Omnis Cellula e cellula (all cells develop only from existing cells).- Implied that there was no Spontaneous generation.

Rudolf Virchow- In 1862 he conducted a famous experiment supporting the theory that cells can only come from other cells.

His experiment:

Steralized flasks with straight and curved necks were used to heat nutrient broths. Bacteria only developed in the straight necks because bacteria cells from the air settled in the S-shaped necks' curves. Spontaneous gen did not produce proven cells in the broth.

Rudolf Virchow's and Louis Pasteur's contradicted the theory of spontaneous generation, which state that a living organism originates from non-living matter.

According to this theory, it was believed that dust creates fleas, maggot arises from the rotten meat, wheat and bread left in the dark corner producing mice.

Louis Pasteur was the first scientist to prove that cells originate from pre-existing cells.

Rudolf Virchow proposed that Omnis cellula e cellula, which means each cell comes from another cell.

All living creatures and body tissues are made up of the smallest unit that can live on its own. The cell membrane, nucleus, and cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates the molecules that enter and exit it.

1.

Freckles are caused by a dominant allele (F).

Marcus and Olivia have recessive homozygotes for the characteristic, ff, if neither of them has freckles.

Olivia's genotype is thus ff.

Marcus has a ff genotype.

Given that they are both recessive homozygotes for the ff gene, there is little chance that their offspring will have freckles.

2.

The straight hairline allele, W is recessive to the widow peak allele, W.

Marcus and Olivia share the hairline trait heterozygosity Ww.

The likelihood of a widow having children is highest when:

Ww = Ww, Ww, Ww, and ww

Widow's peak probability (WW or Ww) equals 3/4

The likelihood that a youngster will have a straight hairline is 1/4.

The likelihood that the offspring will be homozygous

3.

The attached-lobule trait, e, is recessive to the free-lobule trait, E.

The trait, EE, is homozygous dominant in both parents.

One to zero is the ratio of free to connected lobes.

The offspring will be homozygous dominant free lobules, EE, in all cases.

4.

The ability to taste bitter flavors is dominant (T).

Marcus is a recessive homozygote for the trait "tt" since he cannot sense bitterness.

Olivia possesses a "Tt" heterozygote for the trait.

Tt tt equals Tt, Tt, tt, and tt.

There is a 50% chance that each of their kids will try the PTC paper.

Violet's genotype is tt since she cannot taste PTC paper.

5.

T, tongue rolling is a dominant characteristic.

Marcus and Olivia both have tt genotypes since neither of them can roll their tongues.

tt = tt = tt = tt

Therefore;

Their offspring won't be able to roll their tongues.

No hybrids will be born to them.

The entire family shares the genetic tt.

6.

A dimple is a dominant trait (D)

The four youngsters all have dimples.

Therefore,

It's possible that both of their parents carry the dominant allele for the characteristic "DD" or

One of them is heterozygous, or "Dd," and the other is homozygous.

The dominant h0m0zygote "DD" is one of them, while the recessive h0m0zygote "dd" is the other.

The nervous system and muscular system respond to stimuli to produce movement.

The nerve impulse corresponds to an electrical current that propagates through neurons, thanks to a process of membrane depolarization. This depolarization process occurs through stimuli and its function is to transmit certain information to other cells (nervous, muscular or glandular).

With this information, we can conclude that the nervous system and muscular system respond to stimuli to produce movement.

All chordates share some structures during at least some stage of their development. These are the notochord, nerve cord, pharyngeal slits, and tail.

When talking about chordates we are referring to the chordate phylum. Individuals composing this group share four main structures,

The notochord is a dorsal spine precursor from which the nervous system gets formed.

The notochord is present during the whole individual's life (like some tunicates) or during only the embryonary period (like vertebrates).

The nerve cord is dorsally located, together with the notochord.

It is hollow, and, during embryogenesis, it might differentiate into a brain.

This cord connects external stimuli to the motor system to react to them.

Present only during a period of the embryonary stage. These slits give rise to different organs and structures like tonsils, ears, or gills.

All chordates have a tail in at least a period of the organism's development.
