Answer:

The 3 limiting factors that might drive competition within a single species is the food, availability of mates, disease, and shelter (biotic factors) and temperature, climate, sunlight, rainfall, natural disasters, and pollution (abiotic factors).

Explanation:

These factors limit the size of populations. As a population grows, there is more and more competition for the limited resources that Earth provides.

Biotic factors are living things that affect the ecosystem (like when we manually burn/chop down trees and destroy habitats of animals who used to live there).

Abiotic factors are non-living things (natural causes) that affect the ecosystem (like climate change causing the melting of glaciers and mass burning of trees (aka forest fire))

I hope I got it right!! :D

Also if this was for your homework or something, i hope this helps you! :D

Water, Food, and Mates are examples of limiting resources that drive competition. With all of these in place, each species drive to thrive in their environment but they are limited; This creates competition within the species.

TRUE. Bryophytes, which include mosses and liverworts, are generally less adapted to hot and dry climates compared to gymnosperms.

Bryophytes lack a well-developed vascular system and have limited mechanisms to retain water, making them more susceptible to desiccation in hot and dry environments.

On the other hand, gymnosperms, which include conifers and cycads, have specialized adaptations such as thick cuticles, needle-like leaves, and deep root systems that enable them to tolerate and survive in hot and dry climates more effectively.

Bryophytes are a group of non-vascular plants that include mosses, liverworts, and hornworts. They are characterized by their small size, lack of true roots, stems, and leaves, and their dependence on water for reproduction. Here are some key characteristics and adaptations of bryophytes:

DNA profiling is a technology that can identify and distinguish among individuals based on variations in the number of short tandem repeats (STRs) in their DNA.

This technique involves analyzing specific regions of a person's DNA where these STRs occur. By examining the length and pattern of these repeats, scientists can generate a unique DNA profile for each individual. This technology has numerous applications, including forensic science, where it is commonly used to match DNA samples found at crime scenes to suspects or victims. DNA profiling can also be used in paternity testing, genealogy research, and even in wildlife conservation efforts to track the genetic diversity of endangered species.

One of the main benefits of DNA profiling is its ability to provide highly accurate and reliable results. Since the probability of two unrelated individuals sharing the same STR pattern is extremely low, DNA profiling can confidently link a specific individual to a biological sample. In summary, DNA profiling is a powerful technology that can accurately identify and differentiate individuals based on the unique variations in their short tandem repeats. Its wide range of applications, from forensic science to conservation efforts, showcases its value and importance in our modern society.

The false statement concerning Neisseria gonorrhoeae (gonococcus, GC) is that it can be selectively isolated on modified Thayer-Martin (i.e., supplemented hocolate antibiotics vcn).

Neisseria gonorrhoeae is indeed a fastidious gram-negative diplococcus. However, the false part of the statement is the reference to "hocolate antibiotics vcn." The correct term should be "chocolate agar" or "Thayer-Martin agar," which is a selective growth medium used for isolating N. gonorrhoeae. The medium typically contains antibiotics (e.g., vancomycin, colistin, and nystatin) to inhibit the growth of other bacteria and allow for selective isolation of N. gonorrhoeae.

Additionally, it is true that penicillin resistance was followed by fluoroquinolone resistance in N. gonorrhoeae. The CDC currently recommends dual therapy with intramuscular ceftriaxone as a treatment option for gonorrhea.

Answer:

Muscles are involved in the digestive system, immune system, and excretory system.

Ejection of urine and semen through the urethra is accomplished by the action of the "muscular contractions" in the urinary and reproductive systems.

Urine is expelled from the body through a process called micturition, which involves the coordinated action of the detrusor muscle and the urinary sphincters. When the bladder is full, the detrusor muscle contracts, and the internal and external urinary sphincters relax, allowing urine to pass through the urethra and exit the body.

On the other hand, ejaculation of semen is a result of the contraction of smooth muscles in the reproductive system. During sexual arousal, sperm cells produced in the testes travel through the epididymis and mix with seminal fluid to form semen.

Semen is propelled through the vas deferens and the ejaculatory ducts into the urethra by the action of the smooth muscles lining these tubes. At the same time, the bulbospongiosus muscle and the pelvic floor muscles contract rhythmically to expel semen through the urethra and out of the body.

In both cases, the ejection of fluids through the urethra is a well-coordinated physiological process that ensures the proper function of the urinary and reproductive systems.

The  feature of cycads that distinguishes them from most other gymnosperms are they have flagellated sperm and they are pollinated by animals.

option D

Gymnosperms are a group of seed-producing plants that includes conifers, cycads, and others. Unlike angiosperms, which produce seeds enclosed in a fruit, gymnosperms produce seeds that are not enclosed in an ovary.

Cycads are a group of gymnosperms that are particularly distinct from other gymnosperms in a few ways. One of these is their flagellated sperm. Most other gymnosperms, such as conifers, have non-motile sperm that are carried to the egg by wind or gravity. Cycads, on the other hand, have sperm with long, flagella-like tails that enable them to swim to the egg. This requires a film of water, which is why cycads are typically found in habitats with high humidity or near bodies of water.

Based on the given options, Cycads are distinguished from most other gymnosperms by having flagellated sperm, which require a film of water to swim to the egg for fertilization. They are also pollinated by animals, such as beetles and moths, rather than by wind or self-pollination. However, like other gymnosperms, they do have exposed ovules.

Cladograms are scientific hypotheses that can be overturned by new data. This statement is true. Cladograms are diagrams that show the evolutionary relationship between organisms based on various traits. New data can cause changes to be made to cladograms which can result in a change to the interpretation of the evolutionary history of organisms.

Angiosperm plants did not appear until after the extinction of the dinosaurs. This statement is false. Angiosperms, also known as flowering plants, appeared in the fossil record at least 140 million years ago. Although the dinosaurs went extinct around 66 million years ago, angiosperms were already widespread and diversifying by that time.

The definition of an analogous character is "a character that has a similar function to a character in a different organism, but these similarities are due to different evolutionary origins". This statement is true. Analogous characters are traits that have evolved independently in different groups of organisms due to similar environmental pressures and not due to a shared ancestor.

Answer: The chemical reaction between oxygen and glucose that releases energy in cells is called cellular respiration. This process occurs in the mitochondria of cells and involves several steps, including glycolysis, the citric acid cycle, and the electron transport chain.

Glycolysis is the first step of cellular respiration, during which a molecule of glucose is broken down into two molecules of pyruvate, releasing a small amount of energy in the form of ATP (adenosine triphosphate). The citric acid cycle, also known as the Krebs cycle, is the second step of cellular respiration, during which pyruvate is further broken down and more ATP is produced.

The final step of cellular respiration is the electron transport chain, which occurs in the inner membrane of the mitochondria. During this step, electrons are transferred from molecules of NADH and FADH2 to oxygen, releasing a large amount of energy in the form of ATP. The oxygen used in this process is the oxygen we breathe in, and the glucose comes from the food we eat.

Overall, cellular respiration is a series of chemical reactions that converts glucose and oxygen into energy, releasing carbon dioxide and water as byproducts.

The air masses that originate in low latitude are called b) tropical.

Air masses are large bodies of air with similar temperature and humidity characteristics. The air masses that originate in low latitudes near the equator are called tropical air masses. These air masses are typically warm and moist due to the high temperatures and abundant moisture present in tropical regions. As these air masses move away from the equator, they can influence weather patterns and climate in the regions they encounter.

Tropical air masses are important in shaping weather conditions in many parts of the world, particularly in tropical and subtropical regions. When tropical air masses interact with other air masses, such as polar air masses, it can lead to the formation of weather systems, including fronts, storms, and precipitation. Understanding the characteristics and movement of tropical air masses is essential for meteorologists and climatologists in predicting weather patterns and studying climate dynamics.

Covering the land with concrete and asphalt creates natural resource depletion, alters water flow, impairs the growth of vegetation, and can cause the growth of invasive species.

Covering land with concrete and asphalt has adverse effects on the environment. It depletes natural resources during construction and maintenance.

The impermeable surfaces disrupt the natural water flow, altering rivers and increasing runoff, leading to flooding and erosion. Vegetation and trees struggle to grow as concrete and asphalt prevent sunlight, water, and air from reaching the soil.

This impacts biodiversity, wildlife habitats, and the ability of plants to purify the air and sequester carbon. Additionally, the transportation of materials and equipment for construction can introduce non-native species, causing ecological imbalances. Mitigation efforts and alternative land management practices can help alleviate these effects.
