Asthma is a type of respiratory disease in whcih the lung's air passages become too narrow and has excessive mucus production. This will lead a person to experience difficulty of breathing, coughing, and tightness in the chest area. Asthma attacks occur when it is triggered by allergens, strenuous activities, and stress.

We can suspect that Melissa probably has asthma based on the symptoms of coughing for several days and she is experiencing difficulty in breathing.

The advantages of multicellular organism over a unicellular organism is that:

- The multicellular organism can have a longer lifespan because they cells can die and be substitued without the death of the whole organism;

- The multicellular organism can increse in size without limitations because the cells integrate and associated;

- In addiction, multicellularity also permits each cell be able to specialize in different metabolic activities.

- The multicellularity promotes differents types of cells in one organism.

Only 1 out of four individuals from the offspring of a monohybrid cross would be RR.

Option D epigenetic, transcriptional, post-transcriptional, translational, and post-translational levels regulate gene expression in eukaryotic cells.

Epigenetic modifications effect gene expression and have the ability to "turn on" and "turn off" genes, whereas hereditary changes can affect which proteins are created. Since your environment and habits, including diet and exercise, can modify your epigenome, the relationship between your genetics, actions, and environment is easy to comprehend. Epigenetic mechanisms, which regulate how an organism's genome is influenced by its environment, are molecular processes .During transcription, translation, and subsequent protein modification, which normally leads to the production of protein, the genetic information is transferred from the archival copy of DNA to short-lived messenger RNA. Even though every cell in an organism has essentially the same DNA, the qualitative and quantitative changes in gene expression as well as the control of gene expression lead to the diverse cell types and functions.

Answer:

B

Explanation:

Genetic drift is more important in small populations because the chances of an allele being lost or fixed in the population are much higher, this is because each individual in a small population represents a larger proportion of the entire population (than in a large population).

As mitochondria is responsible for cellular metabolism that is why, according to the question mitochondria is the correct answer.

Mitochondria is a cell organelle, originally derived from a theory called endosymbiotic theory. According to this theory, mitochondria went through endosymbiosis that is mitochondria existed as an individual bacterium and was engulfed by a higher-level cell.

Mitochondria is known as the powerhouse of the cell, as it produces all the metabolites for the cellular respiration and metabolism.

Mitochondria produces ATP by number of metabolic pathways such as - glycolysis, where the breakdown of glucose takes place, and it is metabolized into pyruvate. Tri-carboxylic acid cycle or citric acid cycle also known as Kreb's cycle, an eight-step pathway that uses the pyruvate from glycolysis and converts into acetyl Co-A, which gives NADH and FADH2. Electron transport chain, that uses the NADH to transport electrons from highly electronegative complex to electropositive complex.

The vascular tissue of vascular plants is made up of various kinds of cells and components. The primary components of vascular tissue are the xylem and phloem.

Remember that the xylem transports water and dissolved mineral salts and the phloem transports sap made by cells and by photosynthesis.

Therefore, both the xylem and phloem form the vascular tissue of plants.

Now, the formation of the xylem and phloem is given by the vascular cambium. This vascular cambium produces xylem and phloem cells and originates from procambium that has not completely differentiated during the formation of primary xylem and primary phloem.

Now, Xylem can contain three types of elongated cells: tracheids, vascular elements or vessels (tracheae), and fibers. At maturity, when they perform transport functions, all these cells are dead.

Then, the cells of Xylem are:

- Tracheids.

- Tracheas or Vessels.

The phloem consists of two types of conducting cells: sieve tubes, which are the most characteristic elements, and annex cells.

The cells of Phloem are:

- Sieve cell and sieve tubes.

- Albumin cells.

- Companion cells

We can conclude that the correct answer is:

The elements that form Phloem are:

sieve elements, phloem fibers, and phloem parenchyma cells.

The elements that form Xylem are:

long tracheary elements, parenchyma, and fibers.

Clumping and creating plugs in the blood vessel injuries is the function of platelet to stop bleeding. When the skin is cut, the body starts to secrete platelet to stop the bleeding or form a clot until the wound is sealed. This is called positive feedback which contributes to the accelated formation of platelet that fill in the injured blood vessels and to prevent extreme blood loss.

In Support with Alfred Wegener's theory of continental drift, Hess explained how the merged continents have detached into the seven different continents that exist today.

Alfred Wegener's hypothesis state that all continents exist today was attached together in primitive times and existed as supercontinent called as Pangaea . While Seafloor spreading proves that the ocean itself is a site of tectonic activity. Earth in its Shape with Seafloor spreading is just the part of tectonics movement.

Seafloor spreading also give an idea to explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures that occur in the lithosphere that caused movement.

The biological process that is taking place in the picture in the question is called translation (b), meaning the event where the mRNA is translated into a sequence of amino acids (amino acids chain) that form a protein.

Hemophilia is a genetic disorder that makes coagulation slower, which causes the person to bleed easily and for a more prolonged time.

The gene involved is located in the X hromosomes, so females are more likely to be just carriers, because they have two copies of the gene, while males that inherit the defective gene have only one copy, so they express the disease.

If a carrier woman has children with a healthy man, the Punnett square would be as follows:

This means that there i a 525 chance off having a daughter that is a carrier, a 25% chance ofa healthy daughter, a25% chance of a healthy son, and a 25% chance of a son w th hemophilia.

The telogen phase

Explanation:

In the telogen phase, the follicle is dormant or resting. The transition period between the anagen and telogen phases is referred to as the catagen phase. Hairs are routinely lost during the telogen phase and often become a primary source of evidentiary material.

Planting one kind of tree is another form of a monoculture. Monoculture hampers ecosystem functioning, as it diminishes functional biodiversity. Terrestrial ecosystems are a complex network of several species, that interact with constant feedback among themselves. Trees are primary productors, which means they produce the essential nutrients (that is, organic carbon) that other animals will use to nourish and grow. Different types of primary productors begets functional diversity of herbivores (animals that harm them) and also symbiotic diversity (organisms that benefit them). Besides this, tree's diversity promotes soil stability and function, which is critical to keep the ecosystem working in the long run. Without a proper soil, trees will eventually die, which would annhilate terrestrial biodiversity. So, monocultures are not a pretty good idea in places like tropical forest, where there are a lot of different tree species. On the contrary, in ecosystems such as pine forest, where there is one dominant tree species (which is not the same, as only one tree species, it is just that one tree species is more abundant), planting one kind of tree (the dominant one) could be a good practice to restore the ecosystem.

Answer:

Some disadvantages of planting one kind of tree include:

1. Loss of biodiversity (the variety of life in the world or in a particular habitat or ecosystem).

2. They don't provide the necessary amount of nutrition/food.

3. It just takes up a lot of space in the future for when you could be building a farm or something.

A pigment is a generic term for a molecule that absorbs light and has a color. Plants contain many pigments, giving rise to the various colors we see. Flowers and fruits obviously contain a large number of organic molecules that absorb light. Leaves, stems and roots also contain a variety of pigments.

The correct answer is D. Sunning themselves

Sunning or sunbathing is a method used by the organism to raise its body temperature.

The options changes in blood flow, panting, and sweating are means of the endotherms to cool their body temperature.

The mRNA is used to synthesize polypeptides in a process called translation, and for that the mRNA is interpreted as a series of groups with three nucleotides each, called codons. So for each three letters, we have a codon. The codons transcribe the following amino acids: Alanine, Arginine, Asparagine, Aspartic acid, Cysteine, Glutamic acid, Glutamine, Glycine, Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Proline, Serine, Threonine, Tryptophan, Tyrosine, Valine, Selenocysteine.

The codons are organized in a chart, as the one that follows:

As the translation starts with an AUG codon, we sometimes have to leave some trios behind. The answer would be as follows:

1. AUG - met | GGG - gly | AUA - ile | CGC - arg | UAC - tyr | CCC - pro

The sequence would be MET-GLY-ILE-ARG-TYR-PRO

2. We will start only after the AUG codon

AUG - met | CUA - leu | AUC - ile | CCU - pro

The sequence would be MET-LEU-ILE-PRO

3. Again, we start after the AUG codon, and if the stop codon shows up the translation stops

The sequence would be only AUG - met | UAA - stop

MET

4. AUG - met | CGG - arg | UCA - ser | GCC - ala | CCG - pro | UGA - stop

The sequence would be MET-ARG-SER-ALA-PRO

In order to determine whether a trait is dominant or not, you must have an organism that is known to be heterozygous. Parental phenotype that occurs in a heterozygous organism is dominant. Trait that reappear in f2 generation is recessive .

Identification of genotype of an organism with a dominant phenotype, one Test cross must be done .

If an organism exhibiting a dominant trait is homozygous or heterozygous for a specific allele, It is needed to  perform a test cross.

Scientists believe that over 99 percent (D answer option) of species that once existed on Earth are now extinct. This can be known by archeologist research, which allows us to know what species lived in the past by studying the soil, its different layers, and the found fossils, dating with high precision how many years ago those organisms inhabited our planet. With these research tools, we have known that there were at least five massive extinctions on the Earth, where aquatic and terrestrial species perished, and they are the Ordovician-Silurian (around 440 mya), Devonian, the Permian-Triassic, the Triassic-Jurassic, and the Cretaceous-tertiary (65 mya) extinctions.

Answer:

The answer is the first option. The trailing edge is composed of many filopodia containing tight parallel bundles. These filopodia push trailing edge away from the location it was previously occupying.

Explanation:

Cells migrating in tissues exhibit both filopodia and lamellipodia. These thin protrusive extensions are ideal for exploring and penetrating tissue spaces. They are also well suited for intercalating between cells, such as during the migration of leukocytes across endothelial layers.

Therefore the answer is the first option.

According to historians, when did humans first become interested in fitness ever since the beginning of civilization after the Industrial Revolution.

When we look back at human history, there seems to be a correlation between industrial developments and fitness. Early man had no means of propulsion. Food was a task that required walking, running, and abilities that the majority of people in this modern period can hardly even imagine. Back then, what we now refer to as exercise was simply a way of life.

Our bodies started to change in the past when man made the transition from a nomadic existence as a hunter to a sedentary one as a farmer. Despite the work, only specific body areas would receive workout, and the activities became repetitious.
