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.

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.

In a population with long fur, there will be more guinea pigs than short fur in the given scenario.

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.

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.

Explanation:

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.

The variables that Pasteur changed in his experiment to test the hypothesis of  spontaneous generation is the shape of the flask

Pasteur in 1856 was known for his contribution to the science world through the study of the causes of spoilage in beer and wine. He demonstrated his knowledge from his discovery of the properties of fermentation by microorganisms.

He demonstrated and discovered that airborne microbes were the cause of food spoilage not a spontaneous generation with his swan-neck flask experiment. He went ahead with a suggestion that if microbes were responsible for food spoilage and fermentation, they could also be responsible for causing infection and this was the foundation for the germ theory of diseases.

In the later year, Pasteur established his previous experiment with a new one. In this new experiment, he made several flasks with long, twisted necks called the swan-neck flasks where he boiled broth and sterilized it. The essence of the swan neck design is to inhibit the introduction of airborne microorganisms into the flask by trapping them between the twists and bends of the flask and also to allow the exchange of air in the flask with the surrounding air.

Based on the theory above, we can conclude that the variables that Pasteur changed in his experiment to test the hypothesis of  spontaneous generation is the shape of the flask

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.

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.

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).

Answer:

In some aspects, the fungal life cycle is contrary to vertebrates. In most fungi, hyphae with haploid nuclei are the dominant stages. Two nuclei from neighboring hyphae merge into a diploid zygote during sexual reproduction. The zygote undergoes meiosis after a brief period of time.

Explanation:

The haploid (called spores) cells produced from this process become new haploid hyphae. In the bread mold, the haploid hyphae form many haploid springs which can go to other places and lead to new hyphae. Most fungi can also reproduce asexually. Note that mitosis (why?) causes these spores. This asexual reproductive process is a distinct cycle and is more widespread in most fungi than the sexual life cycle. The characteristic black dots found on molten bread, for example, are clusters of asexually produced spores. See this animation which describes the bread mold life cycle.

Unique and complex fungal life cycles. Fungi breed sexually either cross-fertilization or self-fertilization. The Haploid fungus has gametes at tips and generates hyphae. There are two different types of matches (marked as "+ type" and "– type").

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.
