What would happen to the sea lamprey population if it never reproduced? and what must a sea lamprey do in order to be a predator? thank you

Answers

If the sea lamprey population never reproduced, it would eventually go extinct. Reproduction is essential for the survival of any species. In order to be a predator, the sea lamprey attaches itself to other fish and feeds on their body fluids. Adult sea lampreys, which are 12-24 inches long, feed entirely on other fish. They are already predators. They are parasitic in nature and have no jaws, but possess a skeleton made of cartilage. In their native ocean, they don't typically kill their hosts, but in the Great Lakes, where no co-evolutionary link exists, they act as predators and can kill up to 40 pounds of fish each over their 12-18 month feeding period. The Great Lakes Fishery Commission is working on several methods to control sea lamprey populations, including the use of a pesticide called TFM and the release of sterile male lampreys. [2][3]

Answers

Sporophytes are attached to the gametophytes; green gametophytes that manufacture food; distinct leaves and roots; mosses. This statement is true.
Alternation of generation:
In mosses, alternation of generations occurs, which is a life cycle that alternates between two distinct phases: the haploid gametophyte phase and the diploid sporophyte phase. Haploid refers to a cell or organism with a single set of chromosomes, while diploid refers to a cell or organism with two sets of chromosomes. In mosses, the green gametophytes are the dominant and photosynthetic phase, which means they manufacture food through the process of photosynthesis. These gametophytes have distinct leaves and roots that help in anchorage and absorption of water and nutrients.
What are sporophytes?
Sporophytes, on the other hand, are the diploid phase that grows on and remains attached to the gametophytes. They depend on the gametophytes for nutrients, making them somewhat like a "parasite" in the sense that they rely on another organism for sustenance. The sporophyte produces spores through meiosis, which then germinate to form new gametophytes, thus completing the alternation of generations in mosses.

Answers

Living things have evolved and changed over time for specific, observable reasons, as stated by evolution. The correct answer is (C).

The process by which a population's genetic material changes over time is called evolution. Changes in genes, novel traits, and new species can all be the result of evolution, which is a reflection of how organisms adapt to their changing environments.

One of the mechanisms of evolution is natural selection. It is more likely that organisms will survive and pass on the genes that contributed to their success if they are better adapted to their environment. This interaction makes species change and veers over the long haul.

Natural selection is based on the idea that organisms with traits that can be passed down better adapt to their environment than other organisms of the same species do. When compared to other members of the species, this enables superior survival and reproduction, resulting in evolution.

Answers

Deforestation of rainforests can have significant impacts on the ecosystem, especially on the plants that inhabit it. The loss of leaves, stems, and roots from deforestation can have negative effects on the water cycle and nutrient cycling in the ecosystem. Leaves play a critical role in transpiration, which is the process by which plants release water vapor into the atmosphere, and also in photosynthesis, which is the process by which plants produce their own food. Stems and roots provide structural support, store nutrients, and help absorb water and other essential nutrients from the soil. The loss of these plant structures can lead to changes in the microclimate and soil properties, affecting the composition and diversity of the plant community and potentially leading to a decrease in overall productivity and biodiversity of the ecosystem.

True or False: DNA polymerase can only work to elongate DNA in the 5` --- 3` direction?

Answers

True. DNA can only be extended by DNA polymerase in the 5' to 3' direction. This is so that the 5' phosphate group and the phosphodiester bond can be formed, which is catalysed by DNA polymerase.

Why does DNA grow 5 to 3 times longer?

Using a deoxyribonucleotide, DNA polymerase separates the two terminal phosphates from the nucleotide's 5' end and then uses the free energy to create a phosphodiester bond.

Why only one way of DNA polymerase action?

DNA polymerase can only synthesise in one direction by extending the 3' end of the previous nucleotide chain because it needs a free 3' OH group to begin synthesis. As a result, DNA polymerase travels in a 3'–5' direction along the template strand.

Alcohol is a central nervous system depressant that affects various neurotransmitter systems in the brain, including the GABA and glutamate systems.

When consumed, alcohol inhibits the voltage-gated calcium channels in the presynaptic neurons, which are responsible for the influx of calcium ions necessary for neurotransmitter release. This results in a decreased release of neurotransmitters, particularly glutamate, which is the main excitatory neurotransmitter in the brain.

As a result, alcohol slows down neurotransmission and leads to a decrease in cognitive and motor functions, including impaired judgment, slowed reaction time, and loss of coordination. The inhibitory effect of alcohol on calcium channels also contributes to its sedative and anxiolytic effects.

Answers

D. Negative charge for the cell, as sodium rapidly enters. An end plate potential is caused by the flow of sodium ions into a cell. This influx of sodium produces a localized negative charge within the cell, which results in a sharp excitatory post synaptic potential (EPSP).

What is Excitatory post synaptic potential (EPSP)?

Excitatory post synaptic potential (EPSP) is an electrical current created when neurotransmitters bind to receptors on the cell membrane of a postsynaptic neuron. This electrical current causes the neuron to become more likely (or “excited”) to release neurotransmitters of its own, leading to a chain of neuronal activity. This excitatory activity results in an action potential, which is the electrical signal released by neurons when they become “activated”. EPSPs are the basis for the way neurons store and pass along information in the central nervous system.

Answers

Selective perception occurs during the Stimulation stage of perception.

To explain, the perception process consists of three stages: Stimulation, Organization, and Interpretation. During the Stimulation stage, our senses are exposed to various stimuli, and we selectively focus on certain aspects while ignoring others. This selective focus is influenced by our past experiences, beliefs, and expectations.

This is where selective perception comes into play, as we tend to perceive things in a way that conforms to our preconceptions or mental templates.

The Primacy effect also plays a role in selective perception, as it suggests that our initial impressions tend to shape our overall perception.

In summary, selective perception occurs during the Stimulation stage, when we are exposed to stimuli and choose to focus on certain aspects based on our past experiences, beliefs, and expectations.

why are angiotensin-converting enzyme (ace) inhibitors contraindicated in hypovolemia or hypotension? (select all that apply.)

Answers

Angiotensin-converting enzyme (ACE) inhibitors are a class of drugs commonly used to treat hypertension. They work by inhibiting the conversion of angiotensin I to angiotensin II, a powerful vasoconstrictor, thus reducing blood pressure..

However, in cases of hypovolemia (low blood volume) or hypotension (low blood pressure), the use of ACE inhibitors can be contraindicated. This is because ACE inhibitors can further decrease blood pressure, which can worsen hypotension or hypovolemia and potentially lead to hypoperfusion of vital organs.

Therefore, caution should be taken when prescribing ACE inhibitors to patients with low blood volume or pressure, and alternative treatment options should be considered.

true or false once a couple makes a commitment to an intimate relationship is made by a couple, the relationship culture becomes static.

Answers

The statement "once a couple makes a commitment to an intimate relationship is made by a couple, the relationship culture becomes static." is false.

A relationship culture is not static even after a commitment is made because it evolves continuously based on various factors. Couples need to adapt to changes in their lives, such as personal growth, external circumstances, and evolving communication styles.

As a result, relationship culture requires ongoing effort and nurturing to maintain a healthy and successful partnership. Open communication, understanding, and flexibility are crucial components for a couple to effectively navigate changes and challenges throughout their relationship.

Fungi are necessary evil. Justify​

Answers

Answer:

The statement "fungi are necessary evil" is not an accurate representation of the role of fungi in the natural world. Fungi play a crucial role in many ecosystems and are essential to the functioning of the biosphere.

Firstly, fungi are decomposers and are responsible for breaking down dead organic matter and recycling nutrients back into the ecosystem. Without fungi, dead plant and animal material would accumulate and ecosystems would become choked with debris, leading to a decline in biodiversity and productivity.

Secondly, fungi form important symbiotic relationships with other organisms, including plants. Many plants rely on mycorrhizal fungi to help them absorb water and nutrients from the soil, and some fungi can even help to protect plants from pathogens and predators.

Thirdly, fungi have important applications in medicine and industry. For example, the antibiotic penicillin is derived from a species of fungi, and other fungi are used to produce food and beverages such as bread, beer, and cheese.

Overall, the role of fungi in the natural world is far from being a necessary evil. Fungi are essential to the functioning of ecosystems, support the growth and survival of many other organisms, and have important applications in medicine and industry.

Fungi are living organism that feed on others and are very harmful if came with contact.
