Answer: Tomato plant is a multicellular organism.
Explanation: A multicellular is a organism composed by many types of cells or cell lines. A tomato plant is composed not only by million of cells but by many types of them in the different tissues and organs, for example, leaves have epidermic cells that protect them, stomata cells for gas exchange, chlorenchyme cells that have chloroplasts to do photosynthesis, phloem and xylem cells to transport fluids, etc.
Felicia's teacher gives her the following list of types of organisms:
1. Ferns
2. Mushrooms
3. Algae
4. Insects
Protists, like Cryptomonads and Diatoms, are often unicellular and photosynthetic. Fungi, like Yeast and Agaricus bisporus, absorb nutrients from other organisms, distinguishing them from plants. Algae include various photosynthetic organisms important in aquatic ecosystems.
Explanation:The subject at hand involves understanding the classifications and characteristics of various organisms within the fields of biology and ecology. When asked to name two types of protists and two types of fungi, one could mention, as examples, Cryptomonads or Diatoms for protists, and Yeast or the common mushroom, Agaricus bisporus, for fungi. Protists are often unicellular and can be photosynthetic like Cryptomonads and Diatoms, while fungi such as Yeast and Agaricus bisporus are not capable of photosynthesis and instead absorb nutrients from their environment.
It's important to note that while plants undergo photosynthesis, fungi do not; they absorb nutrients from other organisms. This distinct mode of nutrition separates fungi from plants and places them in a unique kingdom of their own. Moreover, organisms like algae, which encompass a wide range of photosynthetic organisms such as seaweed or unicellular algae like Acetabularia, are key components of aquatic ecosystems.

Objective means that they are "facts", and do not include personal thoughts and beliefs (which is subjective).
In this case, your answers are:
1) Fact:
Facts are made based on data and analysis, and are supported by details and other known "facts" or truths. This means that they are right in any circumstances in most cases, or at least in the given circumstance that is provided.
2) Data:
Data is used to support the fact, which is objective. Without data, the claim would be seen as a opinion, or subjective, in meaning, a "I feel that it is this way". Without data, you will not have facts.
It is not:
3) Opinion:
Opinion is the antonym of Fact, and so if Fact is a answer choice, then Opinion is not. Opinion is based off of feelings, personal knowledge, and personal preferences. While useful in some cases, it is not objective.
4) Theory:
A theory is not objective, because it is a opinion that is provable (but is yet to be proven). This makes it subjective, until proven right.

What are two ways animals contribute to the carbon cycle?
Final answer:
Animals contribute to the carbon cycle by exhaling carbon dioxide during respiration and via methane production in animal husbandry practices, both of which affect atmospheric carbon levels and can contribute to global warming.
Explanation:
Animals contribute to the carbon cycle in several significant ways. Firstly, they participate by releasing carbon dioxide (CO2) into the atmosphere as a byproduct of cellular respiration. When animals breathe, they take in oxygen and release CO2, which is a critical component of the global carbon cycle. Secondly, through the practice of animal husbandry, humans rear large numbers of livestock for food, which further contributes to the carbon cycle. These animals not only respire, releasing CO2 but also produce methane (CH4), a potent greenhouse gas, through enteric fermentation. Hence, animals influence both the natural carbon exchange in ecosystems and the anthropogenic impacts on the carbon cycle that can contribute to global warming.

hair cell divide how many times in a year
Answer:
Hair cells are present inside the inner ear that acts as a receptor of sound. Researchers affirmed that once there is a damage to the hair cell, it can regenerate in birds.
Damage hair cell can lead to loud noise which in turn affect the ear. The supporting cells are present along with the hair cells. When the hair cells get damaged, the supporting hair cell gets the signal to start the process of regeneration.
Hair cells divide rapidly during the anagen phase, which lasts between 2 to 7 years and is marked by the active growth of hair. The hair growth cycle includes a transition phase (catagen) and a resting phase (telogen) before restarting. The growth rate during anagen is on average 0.3 mm per day.
Explanation:The number of times hair cells divide in a year varies, as hair growth occurs in three distinct phases: the anagen phase, which can last from 2 to 7 years and involves rapid cell division at the hair root; the catagen phase, a brief 2-3 week period that transitions from active growth; and the telogen phase, resting for 2-4 months without new growth. At the end of the telogen phase, a new anagen phase begins, during which basal cells in the hair matrix produce a new follicle and push out the old hair. This cycle repeats throughout a person's life, and hair typically grows at an average rate of 0.3 mm per day during the anagen phase.
4. Which of the following was the key point of Darwin and Wallace's theory of evolution by natural selection?
differential reproduction
competition
overproduction
variation
Answer:
differential reproduction
Explanation:
I got it right on a quiz
Final answer:
The key point of Darwin and Wallace's theory is variation, leading to differential reproduction due to competition for limited resources, which causes populations to evolve over time through natural selection.
Explanation:
The key point of Darwin and Wallace's theory of evolution by natural selection is variation among organisms, which leads to differential reproduction as a consequence of competition for limited resources. The process described by Darwin as descent with modification involves these inherently varied organisms reproducing in greater numbers than the environment can support. Thus, those with advantageous inherited traits that confer a competitive edge are more likely to survive and reproduce, passing those traits on to the next generation more frequently than those without such traits. Over time, this leads to a change in populations over generations and results in species becoming better adapted to their local environments, a process known as adaptive evolution.

Explanation:
i got it right on the test
Final answer:
The law of independent assortment, described by A, asserts that genes sort into gametes independently, forming diverse combinations and contributing to genetic variation in offspring.
Explanation:
The correct answer to which best describes the law of independent assortment is A. The factors for each trait are separated independently when sex cells form. The law of independent assortment is an essential principle of genetics first described by Gregor Mendel through his work on pea plants.
This law explains how different genes independently separate from one another when reproductive cells develop. In a dihybrid cross, for instance, the combination of alleles for seed color and seed texture in pea plants assort independently during the formation of gametes. Each allele pairs for different characteristics sort into gametes randomly, leading to a variety of genetic combinations that contribute to genetic diversity in offspring.

Planet Earth is most like a closed system that does not allow transfers in or out of the system
Answer: A. Planet Earth
Explanation:
In a closed system, there is no exchange of mass. However, the energy might get exchanged. The exchange of mass and energy depends upon the property of the membrane or the boundary of the substance or an object.
The Earth is basically a closed framework; it acquires huge amount of energy from the Sun yet the exchange of matter with the outside is just about zero. Material streams between stores or sinks along pathways, or motions.

What would you expect to be the final plant height for a plant grown in eight hours of light?
5 inches
10 inches
15 inches
20 inches
The final height of a plant exposed to eight hours of light per day is dependent on multiple factors, not just light duration. This includes light intensity, temperature, water and nutrient availability, type of plant, and its genetics. Experimental controls are required to determine precise growth results.
Explanation:The final height of a plant grown under eight hours of light/day cannot be determined purely from that information. In biology, plant growth is influenced by a range of factors including light duration, but also light intensity, temperature, water, and nutrient availability, species of plant, and genetic factors. For instance, some plants could potentially thrive under eight hours of light/day and grow to approximately 20 inches, while others may only reach around 5 inches. Controlled experimentation is necessary to determine the specific growth results for a particular plant under an eight-hours-of-light routine.

Without more context, it is impossible to accurately predict the final height of a plant grown in eight hours of light, as plant growth depends on a variety of factors.
Explanation:The final height of a plant grown in eight hours of light is impossible to determine without additional information. Plants need light for photosynthesis, a process where light energy is converted to chemical energy for growth. The plant's height, however, depends on factors like the type of plant, its growth rate which is genotypically determined, the intensity of light, the quality of soil, and the availability of nutrients and water. For instance, some plants might grow just an inch with such limited light, while others might not grow at all. But few might grow substantially.

During mantle convection, heat from the earth's core causes material in the mantle to expand and move upward. When it reaches the top, it __
Answer:
Cools, moves to the side, and sinks, making a circular pattern.
Explanation:
It cools because it dissipates some of this heat to the lower crust. As it moves to the side, it drags along the crust hence powering the tectonic movements. As it cools, the liquid rock becomes denser and begins to sink to the bottom of the mantle as more hot and less dense liquid rock from the bottom rises. This forms a circular convection loop similar to that of water in a container being heated from below.
