Explanation:
True or False: Purine is connected to pyrimidine using oxygen bonds.
Answer:
False
Explanation:
In DNA double helix molecule, there are four types of nitrogenous bases: adenine, guanine, cytosine and thymine. Purines (i.e., adenine, guanine) and pyrimidines (i.e., cytosine and thymine) hold DNA strands together via hydrogen bonds. In base pairing, guanine always pairs with cytosine through 3 hydrogen bonds, while adenine always pairs with thymine by 2 hydrogen bonds. Hydrogen bonds are a type of dipole–dipole interaction where a hydrogen atom is covalently bonded to a very electronegative atom (e.g., Nitrogen or Oxygen).
An electrocardiogram (ECG) provides information about: Group of answer choices the pressure of blood in the heart chambers the rhythm of heart contractions the speed of blood flow through the blood vessels the amount of oxygen in the blood as it leaves the heart
Answer:
the rhythm of heart contractions.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
1. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
2. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
An electrocardiogram (ECG) provides information about the rhythm of heart contractions.
Additionally, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.

describe the "body " structure of a fungus
Answer:
A mass of hyphae make up the body of a fungus, which is called a mycelium (plural, mycelia). The hyphae of most fungi are divided into cells by internal walls called septa (singular, septum). Septa usually have little pores that are large enough to allow ribosomes, mitochondria and sometimes nuclei to flow among cells.

Which type of base is shown? How can you tell?
Answer:
The correct answer is - purine nitrogenous base (adenine).
Explanation:
The base given in the diagram in the image has two rings attach with the pentose sugar which is attached to the phosphate, which means it is the diagram of nucleotide. In this nucleotide base can be either purine or pyrimidine.
Pyrimidines have a single ring structure, whereas purines have 2 ring structures. Adenine and guanine are purines with two ring structures whereas cytosine and thymine are pyrimidines as they have one ring structure. Adenine contains an amine group on C6, and a double bond between N1 and C6.

What will happen to a plant cell placed in distilled water?
The cell will become flaccid due to the cell membrane.
The cell will become turgid due to the cell wall.
The cell will lysis due to the cell membrane.
The cell will burst due to the cell wall.
Answer:
the cell will become turgid due to tge cell wall
Explanation:
when a plant cell is placed in distilled water the water will move in the solution inside the cell is hypertonic to the distilled water serrounding the cell but it will not burst it producr turgor pressure keeping the plant upright
if a plant cell is placed in distilled water, and distilled water has a very low concentration of solutes the cell will become turgid due to the cell wall, hence option B is correct.
How distilled water affect the plant cell?This is because distilled water has a very low concentration of solutes and a high concentration of solvent, making it a hypotonic solution in comparison to the intracellular environment.
To put it another way, we can say that the solute concentration of When a plant cell is placed in distilled water, it becomes turgid.
This is due to the fact that it osmotically absorbs water from the hypotonic distilled water, causing the cytoplasm of the plant cell to enlarge and firmly press up against the cell wall.
Therefore, distilled water has a very low concentration of solutes, so cells will become turgid.

If having long fur helps a guinea pig survive, what
would you expect to see change in the population
as it evolves?
DONE
In a population with long fur, there will be more guinea pigs than short fur in the given scenario.
What is trait?A trait, as it relates to genetics, is a unique feature of an individual.
If having long fur helps a guinea pig survive, we can expect the long-furred trait to become more common in the population as it evolves.
This is because guinea pigs with long fur would have an advantage in colder environments, allowing them to retain body heat more effectively and survive longer.
As a result, longer-furred guinea pigs are more likely to survive and reproduce, passing on their long-furred trait to their offspring.
As this process continues over many generations, the proportion of guinea pigs with long fur in the population will increase, while the proportion with short fur will decrease.
Thus, this can be expected to see change in the population as it evolves.

Hydroelectric power is much cleaner and safer source of energy compared to coal, instead of digging out the Earth, we simply use its natural flowing water. Using hydroelectric power also ensures we do not suffer from the smog and harmful chemicals emitted by coal powered plants. A cleaner environment ensures happier people, a healthier ecosystem, and overall a better place to live. Not all areas can harness local water systems like our Town, we are lucky to even have the opportunity to live on hydroelectric power. Due to this, we can simply use the coal we mine and sell it to other less fortunate towns, while not needing to worry about our electricity or coal economy.

what is the best example of tropism in plants
Answer:
Explanation:
Some plants (flowers or leaves or both) follow the sun as it arcs across the sky each day; sunflowers (Figure below) are a well-known example. This behavior is misleadingly called heliotropism. Helio- does refer to the sun, but a tropism implies growth in a certain direction, and heliotropism does not involve growth.
One example is hydrotropism.

Plant stems can be ______, ______, thick,______, or _________.
Answer:
Underground stem, Aerial stem, and subaerial stem.
Explanation:
Plant stems can be Underground stem, Aerial stem, and subaerial stem due to its presence and strength of the stem. Underground stem are thick stems that run below the ground surface. e.g rhizome. Aerial stems are thin stems that can not stand erect. Examples include watermelon and strawberry etc. Subaerial stems are very thin stems that do not rise up but grow just above the ground. for example, water plantain, flowering rush etc.

Answer:
Receives sperm from the seminiferous tubules.
Explanation:
The rete testis is a set of tubules that transport the sperms from the straight seminiferous tubules, the last portion of the seminiferous tubules, to the efferent ducts. Then, the sperms go to the epididymis conduct. From there, they go to the deferent conduct, then to the ejaculatory duct, and lastly to the urethra.

Compression of mortality is the extent to which an organ can preserve essentially normal function despite decreasing cell number or cell activity. Group of answer choices True False
Answer: False
Explanation:
Compression of mortality refers to the reduction over time with regards to the variance of the age of people at death.
The extent to which the organ can help in preserving normal function despite the fact that there's a reduction in the number or cell activity is referred to as compression of morbidity.
When morbidity is compressed, it should be noted that individuals can be expected to live healthier and longer as well.
Therefore, the statement is false
