What is a major difference between Animalia and Plantae kingdoms?
A) Animals get their nutrients from plants and other animals while plants get their nutrients from oxygen.
B) Plants stop growing when they become adults, but animals continue grow throughout their lives.
C) Plants produce their own food using sunlight and animals need other organisms for nourishment.
D) Animals need water to live, but plants are able to survive without it.
The answer is unquestionably C.
The correct statement about the difference between Animalia and Plantae kingdoms is the following:
Plants produce their own food using sunlight and animals need other organisms for nourishment.What is the Animalia kingdom?They are multicellular organisms and enjoy a high level of specialization in tissues, they are heterotrophic beings, which means that they feed on other living beings and move autonomously.
What is the Plantae kingdoms?It is the kingdom that brings together all forms of terrestrial plant life (trees, shrubs, grass, etc.) and all aquatic algae, as long as they carry out some form of photosynthetic nutrition.
Differences between Animalia and Plantae kingdomsThe members of the Plantae kingdom are all autotrophs, that is, capable of generating their own food from inorganic matter.Members of the Animalia kingdom cannot produce their own food like plants do, so they must consume organic matter from other living things to survive.Therefore, we can conclude that the Animalia kingdom is distinguished from the Plantae kingdom by lacking chlorophyll (they do not photosynthesize) and are heterotrophs.

Explanation:
Why are human populations not limited by the carrying capacity of their ecosystems
Human populations are not strictly limited by ecosystem carrying capacities due to their ability to alter their environments and improve resource availability. However, there are natural limits to growth, and ongoing human expansion poses risks to sustainability and biodiversity. Technological advancements have historically increased carrying capacity, but concerns about ecological constraints and environmental health remain.
Human populations may not be strictly limited by the carrying capacity of their ecosystems due to their unique ability to adapt and modify their environment. Unlike other species, which directly depend on the carrying capacity defined by resource availability, humans have developed multiple ways to increase the resources available to them. Advancements such as the agricultural revolution, the industrial revolution, and modern technological innovations like desalination, solar energy harnessing, and potentially nuclear fusion, have continually shifted the perceived carrying capacity.
However, this does not mean that human population growth can continue infinitely. The concept of limits to growth suggests that there are natural boundaries to how much the Earth can support, considering factors like the photosynthetic capacity of the biosphere, biodiversity loss, and the increasing amount of atmospheric carbon. Long-term exponential growth in human populations poses significant risks such as famine, disease, large-scale death, and social strain manifesting in problems like increased crime.
Furthermore, while humans can indeed alter their environment to support larger populations, this often comes at a cost to other species and the natural ecosystem as a whole. The modification and appropriation of habitat for human use, including through practices like artificial selection for high-yield crops, can lead to environmental degradation and loss of biodiversity. These actions can have detrimental effects on the Earth's overall health and its ability to sustain human populations in the long term.
Can someone please explain to me chemical, mechanical, thermal and electrical energy? Thank you. :)
Answer:
Chemical Energy is released when bonds form in a chemical reaction, often producing heat as a by-product.
Mechanical Energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both.
Thermal Energy is what we call energy that comes from the temperature of matter. The hotter the substance, the more its molecules vibrate, and therefore the higher its thermal energy.
Electrical Energy is caused by moving electric charges called electrons. The faster the charges move, the more electrical energy they carry.

One cat carries heterozygous, short-haired traits (Ss), and its mate carries homozygous long-haired traits (ss). Use a Punnett square to determine the probability of one of their offspring having short hair.
One cat carries heterozygous long haired traits SS and its mate carries homozygous short haired traits ss
a trait that is always expressed. ... One cat carries heterozygous, short-haired traits (Ss), and its mate carries homozygous long-haired traits (ss). Use a Punnett square to determine the probability of one of their offspring having short hair.
Using a Punnett square, the probability of an offspring from a heterozygous short-haired (Ss) and homozygous long-haired (ss) parent having short hair is 50%, since the resulting genotypes would be Ss and ss in equal proportions.
To determine the probability of an offspring having short hair from a parent carrying heterozygous short-haired traits (Ss) and another carrying homozygous long-haired traits (ss), we use a Punnett square. When S (short hair) is dominant over s (long hair), the possible genotypes for their offspring are Ss and ss.
The Punnett square is as follows:
Ss (heterozygous short hair)ss (homozygous long hair)Thus, the probabilities are:Short hair (Ss): 50% or 1/2Long hair (ss): 50% or 1/2Therefore, there is a 50% chance that one of their offspring will have short hair.
If the bald eagle was removed from this food web what effect would this have on this population of the other species?
Answer: The benthic invertebrates would decrease in population size because they are eaten by the sea ducks and the phytoplankton would increase in population size.
Explanation:
Answer:
As tertiary consumers, bald eagles depend on all the levels below them for energy. If their population increases, the ecosystem wouldn’t be able to support this growth because the population of prey animals—sea ducks and fish—would rapidly decrease. This decrease might cause the populations of primary consumers to increase. As a result, primary consumers might feed more on the producers. Over time, there may not be enough producers to maintain the food web.

Which process uses proteins to move molecules against a concentration gradient?
Facilitated Diffusion
Active transport uses carrier proteins to move molecules against a concentration gradient, requiring energy in the form of ATP, as seen in the sodium-potassium pump of nerve cells.
Explanation:The process that uses proteins to move molecules against a concentration gradient is known as active transport. During active transport, carrier proteins or pumps use energy, usually in the form of ATP (adenosine triphosphate), to move substances from an area of low concentration to an area of high concentration. This is crucial for maintaining the necessary concentrations of ions and other substances for cell function, despite the passive movements that tend to even out concentrations.
Examples include the sodium-potassium pump in nerve cells, which is essential for transmitting messages to the brain.

Imagine that muskrats are removed from wetland ecosystem predict what would happen both to producers and to secondary consumers..
producers will increase because a predator will be going away but consumers will decrease because teritary consumers will have to eat
If muskrats were removed from a wetland ecosystem, it would disrupt the balance. The primary consumers' populations could increase, leading to overconsumption of producers and possibly a reduction in biodiversity which cascades to other levels of the food web. The ecosystem might recover over time, however, the state may differ from the original.
Explanation:Removing muskrats from a wetland ecosystem would likely disrupt the equilibrium of the ecosystem. As muskrats, which are secondary consumers, are removed, there will be a change in the population of the species they prey on, which are often primary consumers such as insects and mollusks. These primary consumers could increase in number, potentially leading to overgrazing or overconsumption of the producers (plants and algae).
In turn, this can lead to a decrease in the amount of producers, which would also affect other animals in the ecosystem that rely on these resources. This ripple effect might cause a drastic decrease in biodiversity and could cause irreversible damage to the ecosystem, leading to potential collapse of the entire food web.
The loss of primary producers would initially lead to a disruption in the food web, however, nature has a way of adapting to changes over time and the ecosystem could recover, although it might not be in the same state as before.

If a scientist is studying the attraction of water molecules to each other, what property is he or she studying
The scientist is studying cohesion, a property of water that makes water molecules attract to one another.
Answer:
Cohesion
Explanation:
Cohesion refers to one of the properties of water molecules to get attracted to each other. Since each water molecule an oxygen atom with a partial negative charge and hydrogen atoms with a partial positive charge, water molecules form intermolecular hydrogen bonds. This leads to the tendency of water molecules to stick together, that is, cohesion.
in what three ways are human traits controlled?
They are controlled by single gene with two alleles and other single jeans with multiple alleles
Final answer:
Human traits are controlled by polygenic inheritance, nature-nurture interactions, and natural selection, with factors ranging from multiple gene influences to environmental pressures shaping phenotypic diversity.
Explanation:
Human traits are controlled in three primary ways. Firstly, most traits are polygenic, being influenced by more than one gene, examples include height, skin color, and weight. Secondly, nature-nurture interactions play a significant role; for instance, a person may have a genetic predisposition for height, but environmental factors like nutrition can influence their actual growth. Lastly, natural selection can impact traits over generations, particularly in how phenotypes distribute within a population due to selective pressures from the environment. For example, some traits like skin color or lactase persistence have evolved due to environmental selection pressures.

Why do strawberry cells need dna
DNA manages all the cells activities and "tells" them what to do. DNA also gives coded regulations for the strawberry so that it can create proteins.
What is DNA?Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.
The majority of DNA is found in the cell nucleus (where it is known as nuclear DNA), but there is also a tiny quantity of DNA in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Adenine (A), guanine (G), cytosine (C), and thymine (C) are the four chemical bases that make up the code that stores the information in DNA (T). More than 99 percent of the 3 billion bases that make up human DNA are the same in every person.

to what was cesar Chavez referring when he said. "si se puede"
I'm not gonna lie, I have absolutely no idea but I can at least translate it lol.
It means "You can do it."
Hopefully this helped.... :)
"Si se puede" by Cesar Chavez referred to a message of hope and collective action aiming for social and labor change. This phrase became iconic in the struggle for improving the conditions of migrant laborers in California, emphasizing nonviolent protest and solidarity.
Explanation:To what was Cesar Chavez referring when he said, "Si se puede"? Cesar Chavez's declaration, "Si se puede", translates to "Yes, it can be done" or "We can do it" in English. This statement became a powerful slogan for change and embodied the spirit of solidarity and collective action. Chavez, alongside Dolores Huerta and the United Farm Workers, organized boycotts against the conditions of migrant laborers in California. This movement, particularly symbolized by the boycott of grapes and lettuce in 1973, aimed to pressure growers into improving conditions for farm workers. Chavez's nonviolent approach drew inspiration from Mahatma Gandhi and paralleled the civil rights philosophies of leaders like Martin Luther King, Jr.
The phrase "Si se puede" rallied individuals to believe in the possibility of change through unity and perseverance. It has since transcended its original context to inspire movements for social justice around the world, marking a significant moment in the history of labor rights in the United States.
