Homeostasis is the ability to maintain a constant internal environment in response to environmental changes so organism must need it so they can be balanced internally in response to the environment .

Hope This Helps!  Have A Nice Day!!

Homeostasis is important to the survival of organisms because it allows them to maintain stability in their internal environment and adapt to changing external conditions.

Homeostasis is the ability of an organism to maintain stable internal conditions in response to changes in its external environment. It is important to the survival of organisms because it allows them to function properly and adapt to different conditions. For example, in humans, homeostasis regulates body temperature, blood pressure, and blood glucose levels to ensure optimal physiological functioning.

By maintaining homeostasis, organisms can keep their internal environment within a narrow range of conditions that are necessary for their survival. This stability allows cells and organs to function properly and perform their specific roles. Without homeostasis, organisms would be more susceptible to disease, dehydration, or other disruptions that could threaten their survival.

Overall, homeostasis plays a vital role in the survival of organisms by allowing them to maintain internal stability and adapt to changing external conditions.

Final answer:

Phylogenetic trees represent evolutionary relationships and require homologous traits to accurately trace ancestries and evolutionary pathways. They serve as a map of evolutionary history, showing how species are related and have diverged over time.

Explanation:

A fanlike diagram, known as a phylogenetic tree, is a useful model for phylogenetic classification because it illustrates the evolutionary relationships among different organisms or groups of organisms. The reason it is so important for scientists to distinguish between homologous and analogous characteristics before creating such trees is because phylogenetic trees are based on evolutionary connections. Homologous characteristics reflect a common ancestry, while analogous characteristics may be similar due to convergent evolution but not due to a shared ancestor. Therefore, using homologous traits is crucial for accurately depicting the pathways of descent.

Moreover, the phylogenetic tree serves as a map of evolutionary history. Rooted trees have a single lineage at the base, indicating a common ancestor from which all organisms on the diagram diverged. This can help trace the lineage of a single species and discover common ancestors among various species. On the other hand, unrooted trees show relationships but not a common origin. The hierarchical classification is reflected, showcasing the diversity and comparability of different species over evolutionary time.

In each cell cycle (in mitosis), the total number of cells is double. Thus, option "C" is correct.

Interphase is actually the longest stage of the cell cycle. This is the point where the cell prepares itself for division. It is composed of 3 phases:

G1 phase - is when the cell starts to grow and copies its organelles.

S phase - it starts making copies of its DNA and makes a copy of its centrosome.

G2 phase - continues to grow and produces the proteins or enzymes that will be used in the process.

Thus, option "C" is correct.

Explanation:

When the population attains the condition called carrying capacity, it causes logistic growth in the population.

Answer: Option B

Explanation:

The rate of development of population in an environment depends based upon the number of individuals surviving in the environment. It develops in size gradually when there are just a couple of people whereas it develops quicker when there are more people.  

When the population reaches the carrying capacity of the environment which is nothing but the maximum number of individual which the environment can hold, it causes logistic growth due to non availability of resource as it is exhausted by the surviving population.

option B. Logistic growth in a population occurs when growth slows and becomes steady as the population approaches the carrying capacity of its environment due to limitations in resources.

A population experiences logistic growth when it reaches a point of stability due to limitations in available resources, also known as the carrying capacity. In other words, logistic growth occurs when a population's growth slows down and remains steady as it approaches the carrying capacity of its environment. Initially, growth is rapid, similar to exponential growth. However, as the population approaches the carrying capacity, the resources in the environment are not sufficient for all members of the population, leading to competition and a slowdown in population growth.

Option A does not lead to logistic growth, but rather to exponential growth, which is unrestricted.  Option C introduces a factor that may limit population growth but is not the definition of logistic growth. Finally, option D does not necessarily lead to logistic growth as primary succession refers to the establishment of a biological community in an area with no life.

Explanation:

When a honey bee stings or a pathogen attacks the damaged cells release chemicals.

Chemicals includes

These chemicals cause blood vessels to leak fluid into the tissues, causing swelling.

Processes happened during Inflammatory response:

Inflammation is a defense mechanism in the body. The immune system recognizes damaged cells, irritants, and pathogens, and it begins the healing process. Chronic inflammation can eventually cause several diseases and conditions.

Answer:

The inflammatory response is a type of body response produced in response to damaged tissue, attack of pathogen and or any other cause.

The body shows an inflammatory response in the following manner:

1. Recognition of stimulus- receptors recognize the antigens.

2. Release of inflammatory markers: affected cells produce chemicals like histamine, bradykinin, and prostaglandins.

3. Vascular permeability changes and leukocyte (WBC) recruitment- released chemicals causes the blood vessels to leak fluid causing swelling and attract WBC.

4. Accumulation of leukocytes- WBC performs the process of phagocytosis which eats dead or damaged cells and germs.

Mosquitoes can often transmit viruses from one organism to another, acting as vectors of the virus.

A vector is an organism that carries a pathogen from one host to another. Mosquitoes are vectors for a number of viruses, including dengue, Zika, yellow fever, and malaria.

When a mosquito bites an infected person, it can pick up the virus in the blood. The virus then multiplies in the mosquito's body and can be transmitted to the next person that the mosquito bites.

Mosquitoes are able to transmit viruses because they have a long proboscis, which is a tube-like structure that they use to suck blood. When a mosquito bites, it inserts its proboscis into the skin of the host and draws blood. The virus can then be transmitted from the host's blood to the mosquito's salivary glands. When the mosquito bites another person, it can then transmit the virus through its saliva.

Final answer:

Mosquitoes serve as biological vectors for viruses, for example, the West Nile virus and malaria. They transmit these pathogens directly to hosts through their bites. Preventive measures like using insect repellent and protective clothing are encouraged to reduce the risk of vector-borne diseases.

Explanation:

Mosquitoes can often transmit viruses from one organism to another, acting as vectors of the virus. For instance, mosquitoes are a vector for West Nile virus, which they spread without becoming sick themselves. As biological vectors, mosquitoes can transmit viruses and parasites through their bites, injecting these pathogens directly into the bloodstream of their hosts. Diseases like malaria highlight the complexity of this transmission, as the malaria parasites go through various life stages and can be carried by mosquitoes from humans to other hosts, such as monkeys. Vector-borne diseases require detailed knowledge about the behaviors and environments of both the vectors and pathogens involved. Thus, measures such as using insect repellent, wearing protective clothing, and sleeping in well-screened areas are recommended to avoid bites and reduce the risk of infection.

D. contact metamorphism

Explanation:

When there's a volcanic activity in certain area, very often it happens that there's magma that intrudes into the cold rock in the surrounding area. The intrusion of the hot magma into the cold rock layers causes big changes into the structure of the rocks. The high temperature and high pressure manage to influence the structure of the preexisting rocks, mostly on the places where the magma touches the cold rocks, leading to the formation of metamorphic rocks. This type of metamorphism is known as contact metamorphism.

Answer:

Digestion "cleans out" the digestive system keeping it free of dead cells. It is important because it serves as the "fuel" for cellular respiration. The glucose is used to produce the ATP our body needs to perform essential functions. ATP is like the "energy currency"/"money" that the living cells "run on". The digestive tract provides the nutrient molecules, through the process of digestion, while the respiratory tract provides oxygen. As such, the two systems work together to give your cells the ingredients they need to produce energy, which they use to communicate, build cellular products and grow.

Tow replication forks form a lagging and leading strand.

Explanation:

During the process of DNA replication, there forms a Y shaped junction called replication fork. At each replication origin, two replication forks are formed in opposite polarities.

At one replication fork, a discontinuous stand is formed called lagging strand, and at the other replication fork, there forms a continuous strand in 5' to 3' direction called leading strand.

Tow  replication forks form a lagging and leading strand in DNA replication

It is a point where DNA replication occurs, otherwise called as growth point.  At each origin, two replication forks are formed in opposite polarities.

It is Y-shaped structure forms at the junction between the newly separated template strands and the duplex DNA that has not yet been duplicated.

During initiation step of DNA replication,  one strand can be easily duplicated, while the other strand can not easily duplicated due to polarity problem.

Secondly DNA polymerase synthesizes the DNA strand in the 5′-3' direction only.

Thus, one strand is continuous  or leading strand where as other strand is  discontinuous or lagging strand, generating Okazaki fragments.

Answer:

Option (C).

Explanation:

Reading frames represent a way of reading the sequence of nucleotides in a DNA or RNA molecule into a set of non-overlapping, constitutive triplets.

These triplets are known as genetic codes or codons. There are total 64 codons, out of which 61 code for particular amino acids and three codons provide stop signaling.

So, if a reading frames change in a RNA molecule, it will lead to change in codon sequence and formation of a completely different peptide.  

Thus, the correct answer is option (C).

Answer:

The correct answer is option C. "Without a well-defined reading frame, the peptide made from a given sequence could be completely different".

Explanation:

In molecular biology, the reading frame is defined as the way a nucleotide sequence is divided in triplets, at which each group of three nucleotide (codons) is translated into an amino acid. Well-defined reading frames are critical in protein synthesis, because any change in the reading frame would result in a peptide completely different of the one desired. A clear example of the importance of a well-defined reading frame is seen in frameshift mutations, at which nucleotide insertions or deletions causes leads to the synthesis of a completely different and non functional protein.

C) Gorilla gorilla (gorilla)

Explanation:

At least 15% of our genome is more similar to gorillas than our closest "relatives," chimpanzees.

First, you need to understand a few things. Gorillas, chimpanzees and humans all have one ancestor in common. First, gorillas distinguished themselves and followed their own evolutionary path. Then humans and chimpanzees broke up. That's why the chimpanzee is considered the most human-like animal - and the gorilla the second.

The data showed that the separation of gorillas from our common ancestor took place about 10 million years ago - four million before the separation between humans and chimpanzees.

Or how your muscles keep working when you're exercising so hard that they're very low on oxygen?

Both of these processes can happen thanks to alternative glucose breakdown pathways that occur when normal, oxygen-using (aerobic) cellular respiration is not possible—that is, when oxygen isn't around to act as an acceptor at the end of the electron transport chain. These fermentation pathways consist of glycolysis with some extra reactions tacked on at the end. In yeast, the extra reactions make alcohol, while in your muscles, they make lactic acid.

Fermentation is a widespread pathway, but it is not the only way to get energy from fuels anaerobically (in the absence of oxygen). Some living systems instead use an inorganic molecule other than \text {O}_2O

1. The poison leaf plant, also known as gifblaar (pictured above), contains fluoroacetic acid, a compound that interferes with the Krebs cycle, eventually causing it to shut down completely.

Which of these answer choices best describes the overall effects that would occur in an animal that consumes this plant?  

Oxidative phosphorylation would not occur, the majority of ATP will not form, and the animal will not be able to survive.

2. On cool and brisk day, if you take a deep breath in and then exhale, you'll see a "fog" that forms as a result of your exhaled breath.

Which of the following products of cellular respiration does that "fog" contain?

Carbon dioxide and water

3. What is the correct pathway of anaerobic respiration in yeast?

Glycolysis ⇒ Alcohol Fermentation

Explanation:

1. Fluoroacetic Acid interferes with the Citric Acid Cycle (or Krebs Cycle) as it takes the place of Acetate, and is converted to fluorocitrate, which disrupts the whole cycle as it inhibits aconitase (an enzyme in the Krebs Cycle) and prevents the conversion of citrate to isocitrate. Therefore, oxidative phosphorylation would not occur, and oxidation of nutrients to produce energy would be halted.

2. Cellular respiration consists of several metabolic reactions occuring in the cells in order to convert energy from nutrients into adenosine triphosphate (ATP), carbon dioxide and water. So, the "fog" that forms as a result of your exhaled breath contains water and carbon dioxide. When we breathe, we take in Oxygen, and our lungs exhale Carbon dioxide. Breath also contains moisture from the mouth and lungs, so every breath also has water in the form of water vapor. Therefore, when the weather is cold outside, this water vapor condenses into small droplets of water that can be seen and is what looks like "fog"

3. Fermentation is an anaerobic process (in the absence of oxygen) that breaks down glucose. Under anaerobic conditions, Yeast converts glucose to pyruvate acid through glycolysis. Then NADH donates its electrons to the pyruvate acid (an organic molecule), thus producing ethanol.
