Answer: A. the succession of community is completed

Explanation:

GeoPanther ur answer is wrong, just retook my test and C was wrong, it showed me the correct answer

A climax community is indicated by the stabilization of a community's population and composition, which remains unless a significant disturbance occurs, resulting in the final stage of ecological succession.

Scientists recognize that a climax community has been reached when they observe that the population of a community stabilizes and doesn't significantly change in size or scope, indicating the final stage of ecological succession. This means the succession of communities is completed, resulting in a stable balance of all organisms within the ecosystem.

The climax community will remain relatively stable unless a significant disturbance, like a disaster, alters the ecosystem, starting succession anew. It is important to note that what constitutes a climax community can vary greatly depending on the region's climate and geology, such as tropical rainforests in the tropics or coniferous forests in northern areas.

Answer:

a) Both have an eukaryotic cell type.

   In both multicellularity is present in all forms.

b) Kingdom plantae have a rigid cell wall while in kingdom animalia they lack a cell wall.

  Kingdom plantae autotrophic in nature while kingdom animalia are heterotrophic in nature.

Explanation:

While both Kingdom Animalia and Kingdom Plantae are built from eukaryotic, multicellular organisms, they differ fundamentally in how they obtain energy (heterotrophy vs. autotrophy) and in the structural composition of their cells (absence vs. presence of a cell wall).

The two fundamental characteristics that Kingdom Animalia and Kingdom Plantae share are:

1. Eukaryotic cells: Both animals and plants are made up of eukaryotic cells, which means their cells have a true nucleus enclosed within membranes.

2. Multicellularity: Both kingdoms consist of organisms that are multicellular, meaning they have many cells that work together to perform various functions necessary for survival.

The two fundamental characteristics that are different between Kingdom Animalia and Kingdom Plantae are:

1. Nutrition: Animals are generally heterotrophic, meaning they cannot produce their own food and must consume organic matter from other organisms. In contrast, plants are autotrophic, as they can synthesize their own food through the process of photosynthesis using sunlight, water, and carbon dioxide.

2. Cell wall: Plant cells have a rigid cell wall made of cellulose, which provides structural support and protection. Animal cells do not have a cell wall, which allows them to have a variety of shapes and sizes and to be more flexible.

Kingdom Animalia and Kingdom Plantae are two of the major groups of living organisms. They share some common features due to their eukaryotic nature, but they also exhibit significant differences that reflect their distinct evolutionary paths and ecological roles.

Both animals and plants are composed of eukaryotic cells, which are more complex than prokaryotic cells found in bacteria and archaea. These eukaryotic cells contain membrane-bound organelles, such as the nucleus, mitochondria, and chloroplasts (in plants). The presence of a nucleus is a defining feature of eukaryotes, distinguishing them from prokaryotes.

Multicellularity is another characteristic shared by animals and plants. This trait allows for the division of labor among cells, leading to the development of specialized tissues and organs. This specialization enables complex functions and interactions with the environment.

Despite these similarities, animals and plants differ in their modes of nutrition and cellular structure. Animals are heterotrophs, which means they must ingest organic compounds from other organisms to obtain energy and nutrients. This can involve consuming plants, other animals, fungi, or bacteria. In contrast, plants are autotrophs, capable of synthesizing their own organic compounds through photosynthesis. This process takes place in the chloroplasts of plant cells, where sunlight is converted into chemical energy, fixing carbon dioxide into organic molecules like glucose.

The presence of a cell wall is a key structural difference between plant and animal cells. The cell wall in plants is primarily made of cellulose, a complex carbohydrate that provides strength and rigidity, allowing plants to stand upright and resist mechanical stress. Animal cells, on the other hand, lack a cell wall, which gives them the flexibility to change shape and move. This flexibility is crucial for processes such as immune responses, tissue repair, and the mobility of individual cells like white blood cells.

These differences are essential for understanding the diverse ways in which these organisms interact with each other and their environment."

https://brainly.com/question/13588318

#SPJ3

This sequence accurately describes the process of neurotransmission at the NMJ, which is critical for the activation of muscle fibers."

"The correct sequence of events at the neuromuscular junction (NMJ) that initiate an action potential in the muscle fiber, from first to last, is as follows:

1. Action potential arrives at the axon terminal.

2. Calcium ions enter the axon terminal.

3. Synaptic vesicles fuse to the membrane of the axon terminal.

4. Acetylcholine is released into the synaptic cleft.

5. Acetylcholine binds to its receptors on the junctional folds.

6. Junctional folds become depolarized.

7. Action potential is initiated on the sarcolemma.

Here is the detailed explanation and logic behind the sequence:

1. Action potential arrives at the axon terminal. This is the initial event that triggers the subsequent release of neurotransmitters. The action potential travels down the motor neuron until it reaches the axon terminal.

2. Calcium ions enter the axon terminal. The arrival of the action potential at the axon terminal opens voltage-gated calcium channels, allowing calcium ions to flow into the terminal from the extracellular space.

3. Synaptic vesicles fuse to the membrane of the axon terminal. The influx of calcium ions triggers a cascade of events that lead to the fusion of synaptic vesicles, which contain acetylcholine, with the presynaptic membrane.

4. Acetylcholine is released into the synaptic cleft. Once the synaptic vesicles fuse with the membrane, they release their contents, including acetylcholine, into the synaptic cleft.

5. Acetylcholine binds to its receptors on the junctional folds. Acetylcholine diffuses across the synaptic cleft and binds to acetylcholine receptors located on the junctional folds of the muscle cell membrane (sarcolemma).

6. Junctional folds become depolarized. The binding of acetylcholine to its receptors opens ion channels, leading to an influx of sodium ions and an efflux of potassium ions, which causes a local depolarization of the muscle cell membrane at the junctional folds.

7. Action potential is initiated on the sarcolemma. If the depolarization at the junctional folds is sufficient to reach the threshold, it will trigger an action potential that propagates along the sarcolemma, leading to muscle contraction.

Answer:

I’m pretty sure the answer is covalent

Hope this helps have a good day :) please mark me the brainliest?

Answer: Option (a) is the correct answer.

Explanation:

Atomic number of carbon is 6 and its electronic distribution is 2, 4. Hence, to complete its octet it needs to acquire 4 more electrons from another atom.

Whereas atomic number of hydrogen is 1 and in order to complete its octet it needs to gain one more electron.

So, when a carbon atom comes in contact with 4 hydrogen atoms there there occurs sharing of valence electrons by each atom.

As it is known that a bond formed by sharing of electrons is known as a covalent bond.

Thus, we can conclude that in [tex]C + 4H \rightarrow CH_{4}[/tex] the bond formed between the elements is covalent bond.

[tex]p = 0.29\\[/tex]

Explanation:

According to the Hardy Weinberg’s equation –  

The sum of frequencies of all the allele with in a given population is equal to one around the locus.  

Thus, if p is frequency of trait “A” and q is frequency of trait “B”, then the sum of the allele frequencies i.e p and q is 1

[tex]p + q = 1[/tex] -------------------- Equation (a)

So, if 71 out of  100 organisms are green, then q would be

Answer:

genes

Explanation:

Scientists engineer crops to resist freezing temperatures by altering an organism's genetics, often transferring cold resistance genes from one species to another to create genetically modified organisms. Genetic engineering enhances agriculture but also raises safety and environmental concerns.

Scientists have genetically engineered certain species to be more resistant to freezing temperatures by altering the genetics of these organisms. They utilize genetic engineering to transfer genes that are responsible for cold resistance from one species to another. For instance, a gene giving antifreeze properties from an arctic fish can be spliced into the DNA of a tomato plant, resulting in a genetically modified organism (GMO) that can withstand colder climates. This technique is part of biotechnology and aims to enhance agricultural productivity by creating crops that can endure challenging conditions such as frost, which would normally destroy them.

The field of biotechnology and genetic engineering has led to the creation of transgenic plants and animals. This technology is applied not just to increase freeze tolerance, but also to enhance resistance to diseases, pests, and pesticides, improve nutritional content, and aid in the ripening process of food crops. While the development of genetically modified foods has primarily been driven by the goal of improving crop yields and quality, it has also raised issues concerning consumer safety and environmental implications.

Answer:

the answer is b

Explanation:

Available energy decreases as trophic levels increase. Therefore, option (B) is correct.

This is because energy is lost at each step in the food chain due to inefficiencies in energy transfer and metabolic processes. Primary producers, such as plants, convert a small portion of the Sun's energy into chemical energy through photosynthesis. Primary consumers, such as herbivores, eat the plants and extract some of the stored energy.

However, only a portion of the energy in the plants is converted into the herbivore's biomass, and some energy is lost as heat and waste products. Secondary consumers, such as carnivores, eat the herbivores and extract even less energy. Tertiary consumers, such as top predators, eat the carnivores and extract the least amount of energy. Therefore, the energy available to organisms decreases as you move up the trophic levels.

Contractile

Explanation:

Answer:

The correct option is D.

Explanation: The options attached to this question are given below:

A) Bacteria from other animals replace those killed by the antibiotics.

B) The few surviving bacteria that are affected by the antibiotics develop immunity to the antibiotics, which they pass on to their progeny.

C) The antibiotics cause new mutations to occur in the surviving bacteria, which results in resistance to antibiotics.  

D) The antibiotics kill susceptible bacteria, but the few that are naturally resistant live and reproduce, and their progeny repopulate the host animal.

E) The antibiotics persist in soil and water.

Antibiotics are sometimes used in animals to control infections. With time, the microbes that are been targeted with the antibiotics usually develop mutations, which makes the antibiotics to become ineffective, thus, the antibiotics will only be able to kill the susceptible microbes while the ones that have developed resistance will remain and give birth to young ones that are also resistant to antibiotics.

The practice of adding antibiotics to animal feed results in the development of antibiotic-resistant bacteria because it encourages the survival of resistant strains, which can be transmitted to humans.

The use of antibiotics in animal feed leads to antibiotic-resistant bacteria because these drugs are given to livestock in low doses, which promotes the survival and reproduction of bacteria that are naturally resistant to antibiotics. In the United States, it is estimated that 70% of the antibiotics produced are fed to animals as a way to enhance production, rather than to prevent disease. This practice encourages the natural selection of resistant strains of bacteria, which can then be transferred to humans, increasing the challenge of treating bacterial infections effectively. The emergence of antibiotic-resistant bacteria due to the excessive use of antibiotics in livestock highlights the need for more judicious use of these drugs, including regulatory changes and increased public awareness.

Answer: (C)

Explanation: well bacteria is what decomposes and eats the nasty food or dead things that are no longer living. The bacterias eat on these things causing them to break down in to nutrients which are very very good for plant growth. If we didnt have our bacteria things would not decompose fast enough making nutrients for plants almost impossiable and if this happend animals would not be able to feed of plants or trees

If you could i really need brainlist it would be greatly appreciated :)

In a food web, if bacteria were missing, the community would likely face reduced decomposition rates, resulting in fewer nutrients available for plants. Bacteria are key to decomposition, converting dead organisms and waste into simpler substances for plants to use as nutrients. Without bacteria, this nutrient cycle would be affected.

In this food web, if bacteria were truly absent, the most likely effect on the community would be reduced decomposition rates, which would in turn prevent nutrients from being recycled back into the soil for plants to use. This can be represented by option C: Decomposition rates would be lower, resulting in fewer nutrients being available to the plants.

Bacteria are a crucial part of the decomposition process as they break down dead organisms and waste products, converting these materials into simpler substances that can be used by plants as nutrients. This cycle is essential in every ecosystem as it ensures that nutrients are not lost but are instead recycled. Hence, without bacteria, this decomposition process will be hindered, affecting nutrient cycling and the health of the community.
