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.

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.

Which of the following variables did Pasteur change in his experiment to test the hypothesis of
spontaneous generation?
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

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.

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.
list two ways that the fungal life cycle is different from the animal life cycle
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").

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.

Question 7
In prokaryotic cells, the ribosomes:
O A. synthesize proteins
O B. synthesize nucleic acids
O C. synthesize sugars
O D. synthesize fatty acid
Answer:
[tex]\boxed {\boxed {\sf A. \ Synthesize \ proteins}}[/tex]
Explanation:
The ribosomes are small organelles made of RNA and proteins. Its function is the same in both prokaryotic and eukrayotic cells: protein synthesis.
The process begins in the nucleus. The DNA and genetic information is housed here. Certain sections are transcribed and copied to make messenger mRNAs that can fit through the nucleus and pores to travel out to the ribosomes.
The ribosomes use the mRNA in a process called translation. They match each set of 3 nucleotides (a codon) in the mRNA to 1of 20 different amino acids. A special sequence of amino acids forms, the molecule folds, and a protein is formed.
So, a ribosome is the main site for protein synthesis and the correct choice is A.

All of the above E. None of the above
Answer:
The correct answer is - D. all of the above.
Explanation:
Hydrophilic hormones are the hormones that can not pass through the cell membrane as they are poorly lipid-soluble and cannot pass through cell membranes and bind the receptors present on the surface of the membrane.
Insulin and glucagon are peptide hormones that bind to a receptor in the target cell's membrane surface. Norepinephrine and epinephrine are catecholamines that are hydrophilic in nature. Seratonin and Melatonin are also bound on the surface receptor due to their hydrophilic nature.

O X: negative
Y: negative
OX: positive
Y positive
Answer:
X: positive
Y: positive
Explanation:
The charges of the objects are:
OX: positive
Y: negative
The concept of electric field lines is a way to visualize the electric field around a charged object or group of objects. Electric field lines point in the direction of the electric field at each point, and the density of the lines corresponds to the strength of the electric field.
By following the direction of the field lines, we can make an inference about the relative charge of the objects. For example, field lines that originate from a positive charge will terminate on a negative charge, while field lines that originate from a negative charge will terminate on a positive charge.
Therefore, based on the field lines, we can determine that:
Option 1 is incorrect, as the field lines terminate on a negative charge.
Option 2 is incorrect, as the field lines originate from a negative charge.
Option 3 is incorrect, as the field lines originate from a negative charge and terminate on a negative charge.
Option 4 is correct, as the field lines terminate on a positive charge.
