Answer:
Sperm cannot be delivered to the urethra.
Explanation:
The testes produce sperm and store it in the epididymis. The epididymis ejects the sperm through the vas deferens into the urethra. Sperm exits the body from the urethra. The incision or cut to the vas deferens prevents sperm from passing from the testis to the urethra.

Question 17 (5 points)
The elements in Groups 3 through 12 of the periodic table are the
actinides
alkaline earth metals
transition elements
halogens
Answer:
transition metals/elements
Explanation:
why could a loss of chlorophy 2 limit cellular respiration in plants
Unlike heterotrophs that take-in organic molecule (through ingestion) for cellular respiration, plants are autotrophs and therefore make their own organic molecule from abiotic factors. They do this through photosynthesis. Loss of chlorophyll pigment, that is significant in photosynthesis, would cause the plant to be unable to create glucose molecules. The plant would subsequently be limited in carrying out cellular respiration that occurs in the mitochondria.
why are bacteria needed in the nitrogen cycle
Bacteria, particularly cyanobacteria and rhizobia, play a crucial role in the nitrogen cycle through the process of nitrogen fixation. They convert inaccessible atmospheric nitrogen into a usable form (ammonia) for plants and animals, acting as natural and sustainable fertilizers. This process allows nitrogen to be incorporated into proteins and nucleic acids, supporting growth in terrestrial ecosystems.
Explanation:Bacteria play a vital role in the nitrogen cycle, particularly through a process known as nitrogen fixation, a biological process where atmospheric nitrogen (N₂) is converted into ammonia (NH3). Some bacteria like members of the genus Rhizobium and cyanobacteria perform this independently, while others, collectively known as rhizobia, interact symbiotically with legume plants to assist in nitrogen fixation. These bacteria, housed in specialized structures called nodules on legumes, convert atmospheric nitrogen into a form that is usable by plants and animals, essentially acting as a natural and sustainable fertilizer.
Nitrogen becomes incorporated into the proteins and nucleic acids of the organisms, leading to growth and development. The nitrogen fixation process is particularly vital as the nitrogen available in the atmosphere cannot be used directly by most living organisms. Therefore, through the conversion of atmospheric nitrogen to ammonia, these bacteria make nitrogen accessible and usable for terrestrial ecosystems.

Farmers have taken advantage of some plants that can reproduce without fertilization. This process allows plants to grow much faster and is known as
A. alternation of generations.
B. vegetative reproduction.
C. fruit reproduction.
D. double fertilization.
Answer:
The correct answer option is B. vegetative reproduction.
Explanation:
Some plants can reproduce without involving fertilization. This process allows plants to grow much faster and is known as vegetative reproduction.
Vegetative reproduction is a type of asexual reproduction in plants which means that only one plant is able to produce an offspring on its own.
Since there is no involvement of another plant to reproduce, therefore this process is faster than sexual reproduction.
When the herbicide glycoladehyde is applied to a plant, it’s cell are unable the Calvin cycle
Final answer:
Glycoladehyde inhibits the Calvin cycle in plants, leading to decreased glucose production and altered water balance, necessitating monitoring of changes in the plant, including growth, dormancy, and water conservation strategies like photorespiration.
Explanation:
Effects of Glycoladehyde on the Calvin Cycle
When the herbicide glycoladehyde is applied to a plant, the cells are unable to complete the Calvin cycle, an essential part of the photosynthesis process. The Calvin cycle uses energy from ATP and NADPH produced in the light-dependent reactions to fix atmospheric carbon dioxide into organic molecules like glucose. A key enzyme in the Calvin cycle is RuBisCO, which catalyzes the fixation of CO₂. However, when glycoladehyde is applied, it inhibits this cycle, resulting in reduced glucose production and a disruption in the plant's water balance. This can lead to the plant resorting to photorespiration, which is less efficient and produces cytotoxic by-products like phosphoglycolate. Additionally, the accumulation of abscisic acid (ABA) in response to stress can inhibit growth and promote dormancy in plants. In extreme cases, the plant may stop photosynthesizing for extended periods until favorable conditions return or switch to anaerobic metabolism.
Likewise, if the function of the cork cambium is impaired by an herbicide, it is important to monitor changes in the woody plant structure, as the cork cambium is responsible for producing cork cells that form part of the bark, playing an important role in protecting the plant.

How does the brain primarily interpret the strength of a stimulus in the nervous system?
A. Based on the size of the action potential
B. Based on the frequency of the action potential
C. Based on how much potassium is in the nerve cell
D. Based on which chemicals are released at nerve junctions
Answer:B. Based on the frequency of the action potential.
Explanation:
The brain primarily interpret the strength of a stimulus in the nervous system based on the frequency of the action potential.
Answer: Option B
Explanation:
The sign that is transmitted down the axon is called action potential. It passes quickly through the axon. At the axon terminal the entry of the action potential by and large causes the arrival of a transmitter that influences the layer of the objective neuron.
The activity possibilities imprint times at which the cell layer at the neuronal cell body arrives at the terminating limit. In this manner, there is an arrangement of action potential containing data about the layer potential at the neuronal cell body.
It is the data conveyed by the train of activity possibilities that gives data at the projection focuses for the neurons. Thus it is inferred that brain uses the frequency of the action potential to interpret the primary stimulus.

Streams erode their channels by abrasion, by dissolving soluble material, and by _____. layering polishing grinding evaporation
Answer:
grinding
Explanation:
The streams are very powerful agents when it comes to erosion. With their power and chemical composition, the streams manage to erode the rocks easily and even the hardest rocks experience significant changes or are totally destroyed over time. The water of the streams manages to break down the rocks into small or big pieces, and as it does it moves them away. The rocks that are carried are constantly colliding with other rocks along the way, causing even more pieces to break and to be eroded, thus the grinding type of stream erosion.
Answer:
The correct answer is grinding.
Explanation:
The ability of a water stream to erode and transport materials that it has collected from the ground during the water cycle depends largely on the speed with which it moves. A current channel is the direction in which water moves in a current.
These currents perform erosion by lifting loose particles by abrasion, and grinding and dissolving the soluble material they collect. The faster the water moves and produces greater turbulence, it will produce greater erosion.
The three ways to transport sediments during this cycle are: in solution, in suspension and sliding or rolling along the bottom.

Although air is full of nitrogen, it is not available for organisms to readily use.
Nitrogen is changed into which substances before being used by living
things?
Answer:
Nitrogen is changed into AMMONIA, NITRATES AND NITRITES before it can be used by living things.
Explanation:
Nitrogen is the most abundant element in the atmosphere, approximately 78% of the air is made up of nitrogen. Despite the abundance of nitrogen, the element can not be used directly by plants and animals.
Nitrogen fixing bacteria that are found in the soil are the ones responsible for converting atmospheric nitrogen into the forms that can be used by plants. Nitrogen fixing bacteria convert atmospheric nitrogen to ammonia while nitrifying bacteria convert ammonia to nitrates and nitrites. Plants use ammonia, nitrates and nitrites to make organic molecules.
All living organisms use nitrogen to make various compounds such as DNA, proteins, chlorophyll, etc.
After the death of the living organisms containing the nitrogenous products, dentrifying bacteria decompose the nitrates in their body to atmospheric nitrogen.
Answer: Ammonia, nitrates, nitrites - apex

Answer: Their genes are Recessive
If the nucleus of a cell was removed the cell wouldn’t be able to make proteins because
The nucleus contains the cells DNA(genetic material) which is basically the recipe for making proteins. mRNA is first transcribed off of DNA and then in translated(by ribosomes) to polypeptides(proteins).
If the nucleus of a cell was removed the cell wouldn’t be able to make proteins because no matter proteins are manufactured by the ribosome which is present in cytoplasm, the mrna needed for proteins synthesis is manufactured inside the nucleus.
How are proteins made inside the nucleus?Translation is the mechanism used to create new proteins. During transcription, DNA is converted into a messenger RNA (mRNA) molecule. The mRNA formed inside the nucleus then needs to be translated into a protein. To generate proteins, ribosomes, transfer RNA (tRNA), and mRNA collaborate during translation.The three phases of translation are essentially the same, but they go by more elegant names: initiation, elongation, and termination. The ribosome joins the mRNA and the first tRNA at the initiation ("starting") stage, allowing translation to start.learn more about nucleus here:

A gene editing technology called CRISPR-Cas9 uses cellular machinery to change the cell's genetic material. How might this technology be useful in treating diseases like cancer?
Cancer is caused by a defective gene due to mutations. CRISPR-Cas9 tools can be used to edit out these parts of the gene. The tool can snip out and replace a section of DNA with a given DNA. The tool is a harnessed mechanism from bacteria that is a mechanism to identify foreign genetic material such as that of bacteriophages and destroy them.
CRISPR-Cas9 is a powerful gene editing technology that has the potential to revolutionize the field of medicine, including the treatment of diseases like cancer. Its ability to precisely modify specific genes offers new possibilities for targeted therapies and personalized medicine.
Cancer often arises due to specific mutations in genes that regulate cell growth and division. CRISPR-Cas9 can be used to target and edit these cancer-causing mutations, effectively correcting or disabling them. By doing so, it may be possible to inhibit the uncontrolled growth of cancer cells and potentially revert them to normal cells.
CRISPR-Cas9 can be used to modify immune cells, such as T cells, to make them more effective in recognizing and attacking cancer cells. This approach, known as CAR-T cell therapy, has shown promising results in some clinical trials, particularly in the treatment of certain blood cancers.
