The process where animals take in oxygen to breakdown energy from the plants is
a) breathing
b) photosynthesis
c) aerobic respiration
d) digestion​

In intertidal zones of the Pacific Northwest, we can discuss the following terms: "species richness," "intertidal zones," and "sea stars."

Species richness refers to the number of different species in a particular area or habitat. Intertidal zones are the areas between the highest and lowest tide marks along the coastline, where various marine organisms can be found. Sea stars, also known as starfish, are a type of marine invertebrate commonly found in intertidal zones.

Sea stars are known to be voracious predators and play a significant role in shaping the biodiversity of intertidal zones. They mainly feed on shellfish like mussels, which can outcompete other organisms for space and resources in the intertidal zone. By consuming mussels, sea stars help maintain a balance between different species in these areas.

However, in some cases, sea stars can decrease species richness in the intertidal zones of the Pacific Northwest. This can occur when the sea star population becomes too large, and their predation on other species intensifies, causing a decline in overall species diversity. In this case, the sea stars become a dominant species, disrupting the balance in the ecosystem and reducing species richness.

In summary, sea stars can decrease species richness in intertidal zones of the Pacific Northwest when their population becomes too large, leading to an intensified predation on other species, and thus disrupting the balance in the ecosystem.

The process of respiration can be divided into the cellular view to the general (cellular respiration to external respiration). Going from the cellular till the external we have:

1- Cellular respiration

Is the aerobic process by which living cells break down glucose molecules to form energy in the from of ATP, that can be divided in three stages, these are: glycolisis (break of glucose into pyruvate), Citric Acid Cycle (Krebs Cycle), and electron transport chain. In this respiration the cell machinery is responsible for from glucose and oxygen form water and carbon dioxide. All the process is intracellular.

2- Internal respiration

The internal respiration is the process of the exchange of gases between the cells and the tissues (internal environment of the body) by the blood vessels and the circulation od red blood cells that carry these gases (oxygen and carbon dioxide). The path of this process is: nose/mouth, pharynx, larynx, and trachea will have the cells oxigenated, the trachea branches and the bronchi will lead to the lungs when the gases exchanges in the tissue will happen. The red blood cells will do the local capture of the gases and the circulatory system will make those cells go to all the tissues in the body.

3- External respiration

The external respiration is the exchange of gases with the external environment. That process occurs in the lungs where the oxygen diffuses into the blood and carbon dioxide into the alveolar air. The internal and external respiration work together in the overall respiratory process, but one happen in the tissues and the other between external environments.

4- How they work together?

The three process are essential for breathing, that's because they work into different levels of tissue and systemic organization. The cellular is the one in the cells that provide the biochemical reactions necessary to the synthesis and conversion of molecules, being the metabolic basis for the respiration to take place, the internal respiration is responsible to distribute the gases into the tissues to make the cellular step possible, while the external respiration makes possible the exchange outside the tissues levels and makes possible to balance the distribution and concentration of the gases in the body.

Even if all the cells have the same DNA they biochemical function are different, that's because differents sets of genes must be turned on and off in each cell type by the action of enzymes and other molecules. Each cell have the same 20,000 or so genes but they are biochemically selected by the action of molecules as hormones and chemical signaling. Therefore, different cells use different parts of the DNA code as directions.

that healthy daughter cells are produced, allowing the organism to continue growing

Explanation:

Have a great day!

Damaged DNAs have to be repaired before cells can proceed to divide mitotically so as to ensure the integrity of the resulting daughter cells.

During mitosis, the DNA of a dividing cell would have to be shared equally between the two resulting daughter cells.

With damaged DNA, the resulting daughter cells' genomes have already been compromised before they even exist and this might impact their normal existence.

Thus, the integrity of the DNA of a cell that wants to divide must be certified by the cell cycle checkpoints before active division can take place.

Explanation:

The prenatal environment in the womb, where embryos receive differing nutrition and varying levels of exposure to toxic agents, shows the early influence of epigenetics.

Epigenetics is the study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself. Chemical compounds bind to a gene and control how it is expressed, turning it on or off. These chemical compounds are found in the body and act as switches that regulate gene expression, hence the term "epigenetic."When an individual is in the womb, their epigenome is very delicate and can be easily influenced by environmental factors. Epigenetic modifications can influence the growth and development of the fetus and the establishment of future disorders.

In addition to the environment in the womb, lifestyle, nutrition, stress, and toxins exposure are all factors that can influence a person's epigenome. In conclusion, the prenatal environment in the womb shows the early influence of epigenetics, which can have a significant impact on a person's growth, development, and future health.

Answer:

In the presence of lidocaine, the action potential was NOT affected at R1 because lidocaine was applied downstream of R1

Explanation:

Lidocaine is an anesthetic that has the power to neutralize neuromal membranes. This anesthetic power allows the ionic fluxes capable of stimulating impulses to be diffused and this allows a dormancy to be achieved. However, when lidocaine is applied downstream to a molecule or structure, the action potential of that structure or molecule is not affected and it may continue to receive impulses.

Every chromosomal pair splits into two identical, independent chromosomes during anaphase. The mitotic spindle, a component of the cell, divides the chromosomes.

The division of the duplicated genetic material contained in a parent cell's nucleus into two identical daughter cells is known as anaphase, which is the fourth stage of the mitotic process. Each pair of chromosomes splits into two identical, separate chromosomes during anaphase. A structure known as the mitotic spindle separates the chromosomes. The microtubules, which make up the mitotic spindle and are connected to a chromosome at one end and the cell pole at the other, are numerous long proteins that are found in cells. During this process, the centromeres of the sister chromatids split concurrently. Afterward, the spindle pulls the separated chromosomes to the cell's opposite poles.

''Organic farming reduces the cost of farming that benefits the farmers economically and also better the environment.''

Explanation:

The hypothesis i.e. ''Organic farming reduces the cost of farming that benefits the farmers economically and also better the environment.'' This hypothesis can be tested by the scientists by taking two fields in different location having same environmental conditions. One field they apply conventional farming whereas other field apply only organic materials and no chemicals. We can see that the cost on expensive fertilizers, pesticides and weedicides can't used in organic farming so it is economically benefitted to the farmers as well as no pollution occurs which happens due to the use of chemicals. Moreover, the price of organic food is 3 times higher due to its non-hazardous nature.

A metapopulation is a regional assemblage of interacting, local populations whose dynamics are influenced by two processes, colonization and extinction. Colonization and extinction are the two processes that influence the dynamics of a metapopulation.

These processes are natural factors that affect the occurrence and disappearance of species in a given area, which is important in the regulation of population dynamics. When the number of colonized habitats exceeds the extinction rate, metapopulations persist. However, when the extinction rate exceeds the colonization rate, metapopulations can become extinct. The term metapopulation refers to the entire group of populations, rather than a single population in a given location.

Each population in a metapopulation can experience independent fluctuations in abundance due to environmental variation, stochasticity, and other factors. In addition, migration occurs between populations, which can help sustain the entire metapopulation.

Clonal selection occurs with both T cells and B cells.

Define clonal selection.

To respond to infections, the body creates B and T cells through a process known as clonal selection. These cells can recognize particular viruses because they each have a different set of receptors. The B and T cells that can identify the intruder grow quickly to produce an army of cells to combat the infection when it enters the host.

Random mutations during clonal expansion result in the development of B cells with higher antibody-binding affinity for their antigens during clonal selection. Secondary immune responses are so successful at preventing reinfection by the same pathogen, which may be explained by the clonal selection hypothesis.

Explanation:

Endothermic feature distinguishes birds from the rest of the reptiles. So, the correct option is (a).

A crucial adaptation that allowed reptiles to exist on land was the growth of their scaly skin, that stopped water loss from the skin. Ectotherms are animals whose primary source of body heat is the environment. Reptiles fall under this category. They control their body temperature using behavioural strategies including self-heating by basking or self-cooling by seeking cover in burrows or shade.

Birds are endothermic, in contrast to reptiles, which means they produce their own body heat through metabolic processes. The feathers on birds, which are repurposed reptilian scales, are what set them apart from other animals. The first birds' feathers allowed them to glide and eventually take to the air in a flapping motion. They also served to insulate the bird's body and aid in the preservation of body heat.
