What evolutionary development allowed plants to grow tall? see concept 29.3 (page 626)?
Final answer:
The development of a vascular system with xylem and phloem enabled plants to grow tall, while the adaptations of seed and pollen facilitated reproduction independent of water and promoted wide dispersion, respectively.
Explanation:
The evolutionary development that allowed plants to grow tall was the development of a vascular system. This system includes xylem and phloem, which are tubes that transport water, minerals, and nutrients throughout the plant. The xylem is responsible for the upward transportation of water and minerals from the roots, while the phloem distributes sugars and other organic nutrients from the leaves to the rest of the plant.
Seed and pollen adaptations were crucial for the development and expansion of seed plants. Seeds allow plants to reproduce without being dependent on water, thus enabling them to survive in a variety of environments, including arid zones. Pollen, with its hardy structure, could be dispersed by wind or animals, reaching far distances and promoting gene flow between plant populations.
These developments provided plants with structural support to grow tall and compete for sunlight, while also being able to spread across vast territories.

Answer:
Jupiter is the largest planet.
Jupiter is the most massive planet.
Explanation:
There are 8 planets in the solar system. Jupiter lies beyond the asteroid belt. It is the largest and most massive planet of the solar system. It does not have retrograde motion. Saturn is the second largest planet and is the least dense planet. Jupiter is composed of mostly hydrogen and helium. Jupiter's axis of rotation is tilted to about 3.13 degrees. It does not rotate upside down.

Does meiosis and mitosis (or both) end with unreplicated chromosomes? Which begins with replicated chromosomes?
Yes, both meiosis and mitosis end with unreplicated chromosomes.
Both meiosis and mitosis end with unreplicated chromosomes because mitosis has diploid chromosomes and meiosis has haploid chromosomes. We know that in mitosis, two daughter cells are produced that has double number of chromosomes each.
While on the other hand, in meiosis, four daughter cells are produced, each has half number of chromosomes. Mitosis is a type of cell division that start with replication of DNA in which exact copy of DNA formed which is distributed equally among the two daughter cells so we can conclude that both mitosis and meiosis end with unreplicated chromosomes.

Why do we classify lionfish populations near the eastern united states as an invasive species? what suggests that these new populations are not an expansion of the lionfish's natural range? view available hint(s) why do we classify lionfish populations near the eastern united states as an invasive species? what suggests that these new populations are not an expansion of the lionfish's natural range? lionfish are native to the tropical pacific. there are no natural water routes of warm water between the pacific and atlantic oceans. lionfish are native to cold waters near the tip of south america. they could not survive in the warmer waters between their native areas and the colder waters of the east coast of the united states. so, it is very unlikely that these south american populations naturally spread north. lionfish are not good swimmers and have no other mechanisms to spread their populations over great distances. lionfish eat only a few specific types of algae that live in isolated regions of the pacific. if lionfish spread much beyond their native pacific home, they would have nothing to eat?
The answer is Lionfish are native to the tropical Pacific. There are no natural water routes of warm water between the Pacific and Atlantic oceans.
Invasive species is a species that colonizes an environment in which it is not a native species and tends to upset the natural balance of that environment. Lionfish are naturally found in the indo-pacific, which is their native environment. However, their presence in the eastern United States has have threatened the ecosystem of the region. The fish has decimated fisheries and reef ecosystem since they also don’t have natural predators in the region. Therefore, their population explodes unchecked.
Lionfish populations near the eastern United States are classified as invasive species because they are not native to that region and have been introduced there by human activity.
Explanation:Lionfish populations near the eastern United States are classified as invasive species because they are not native to that region and have been introduced there by human activity. Several factors suggest that these new populations are not an expansion of the lionfish's natural range. First, lionfish are native to the tropical Pacific and there are no natural water routes of warm water between the Pacific and Atlantic Oceans. Second, lionfish are native to cold waters near the tip of South America, and they could not survive in the warmer waters between their native areas and the colder waters of the East Coast of the United States. Finally, lionfish are not good swimmers and have no other mechanisms to spread their populations over great distances.

Explain why cellular respiration is more efficient when oxygen is present in cells.
Cellular respiration is more efficient when oxygen is present in cells because, in presence of oxygen, a living organism can break down the molecule of glucose into carbon dioxide. This liberates a sufficient amount of energy in order to derive approximately 38 molecules of ATP.
What is Cellular respiration?Cellular respiration may be defined as a type of biological process which utilizes oxygen in order to break down the foodstuff molecules of glucose for the purpose of the derivation of energy, i.e. required for metabolic activities.
When it comes to the absence of oxygen, a molecule of glucose can convert into pyruvate which gives the energy of only two ATP. This demonstrates the efficiency of oxygen during cellular respiration.
Therefore, the process of cellular respiration is more efficient when oxygen is present in cells.

What is the difference between Biogenous and Lithogenous?
When training all major muscle groups in a single strength-training workout, a person should complete when training all major muscle groups in a single strength-training workout, a person should complete single-joint exercises before multiple-joint exercises. large-muscle group exercises before small-muscle group exercises. low-intensity exercises before high-intensity exercises. small-muscle group exercises before large-muscle group exercises?
There are times when the intensity of the exercise is done in stages.
Further ExplanationSingle-joint (single exercise) is an exercise used to train only one part of the body, such as the biceps, legs, and others. Each set of exercises is focused on 1 or 2 body parts only. If arm training, start from light training such as push-ups, then gradually proceed to the intensity of strenuous exercises such as pull-ups or weight lifting. Remember, the intensity of the exercise must be gradual. This is intended to reduce the risk of muscle injury. If the intensity of the exercise is heavy then every wants to "push to the limit" must be carried out with caution, with more coercion then the muscles will spend a lot of energy and can reduce oxygen levels in the blood that can cause injury or muscle fatigue. If this happens the risk is great and the time to recover is likely to be rather long. All forms of exercise can be done but must understand your own abilities to avoid risks. Even a professional bodybuilder is also still at risk of injury. Therefore, the level of exercise intensity must be considered.
Rest and recovery have an equally important role in boosting the volume and intensity of your exercise program. For that, do not force to train all parts of your body so that muscle and energy are not concentrated. Make a proper training schedule. Remember, to train small body parts but using extreme weights will spend a lot of energy. For that, you need to take adequate rest and adequate nutrition.

Which theory of emotion includes a simultaneous arousal and interpretation of emotion?
A) James -Lange theory
B) canon bard theory
C) common sense theory
D) confirmed arousal theory
The correct answer is option B, that is, Cannon-Bard theory.
The Cannon-Bard theory of emotion also called the Thalamic theory of emotion. It is a physiological illustration of emotion created by Walter Cannon and Philip Bard. The theory states that one feels emotions and encounter physiological responses like trembling, sweating, and muscle-tension at the same time.
The Cannon-Bard theory suggests that one encounters physiological arousal and emotion at the similar time. The theory offers more attention to the role of outward behavior or thought that than was done by James-Lange.
