Eukaryotic transcription is different than bacterial transcription because eukaryotic transcription ________.

Answer:

The molecules of ADP and NAD+, resulting from the reduction reaction, return to the light-dependent reactions to be re-energized. One of the G3P molecules leaves the Calvin cycle to contribute to the formation of the carbohydrate molecule, which is commonly glucose (C6H12O6).

Explanation:

In the course of Calvin cycle, carbon dioxide molecules (CO₂) are combined with each other and with the electrons and protons from NADPH to form glucose (C₆H₁₂O₆). The glucose formed is stored in the form of starch.

Calvin cycle is a series of chemical reactions which convert carbon dioxide and hydrogen-carrier compounds into glucose. The carbon atoms used to build carbohydrate (glucose) molecules comes from carbon dioxide gas which is exhaled by animals.

The molecules of ADP and NAD⁺, resulting from the reduction reaction of Calvin cycle, returns to the light-dependent reaction to be re-energized. One of the G-3-P molecules leave Calvin cycle to contribute to the formation of the glucose molecule (C₆H₁₂O₆). This carbohydrate is stored in plants in the form of starch.

The choanoflagellates are a group of free-living unicellular and colonial flagellate eukaryotes considered to be the closest living relatives of the animals.

To list ancestral characteristics common to all animals and choanoflagellates, we can consider the following:

1. Both are eukaryotic organisms, which means they have membrane-bound organelles and a defined nucleus.
2. Both are heterotrophic, relying on other organisms for their food source.
3. They both possess a single flagellum, which is a whip-like structure used for movement.
4. Both have collar cells (choanocytes), which are specialized cells for feeding and filtering particles.

To distinguish animals from choanoflagellates by shared derived characteristic of animals, we can look at these features:

1. Animals are multicellular, while choanoflagellates are primarily single-celled organisms.
2. Animals undergo a specific developmental process called gastrulation, forming distinct germ layers, whereas choanoflagellates do not.
3. Animals exhibit tissue-level organization, which allows for specialization and complex functions, while choanoflagellates lack this organization.
4. In animals, cells are held together by specialized structures like tight junctions, gap junctions, and desmosomes, while choanoflagellates do not possess these structures.

Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart.

Explanation:

The light reactions of photosynthesis occur within the Thylakoid membrane of the chloroplast and the calvin cycle reactions occur within the Stroma of the chloroplast.

Photosynthesis is defined as a process in which solar energy is captured and organic molecules are produced. This process is fundamental to the survival of life on the planet and is the main way in which energy enters the biosphere.

In this case, looking at some parts that occur in the photosynthesis process, we have that the Thylakoid membrane of the chloroplast and the calvin cycle reactions occur within the Stroma of the chloroplast.

There is no certain explanation as to where the first eukaryotic cells originated, and the genesis of eukaryotic cells is still a topic of scholarly discussion.

However, a number of theories have been put forth in light of molecular, biochemical, and morphological data.According to one theory, endosymbiosis—a type of symbiotic association between two or more prokaryotic cells—is how eukaryotic cells first evolved.

This model proposes that a smaller, aerobic prokaryotic cell, such as a bacterium, capable of oxidative metabolism, was engulfed by a host cell

The host and the endosymbiont eventually developed a mutual reliance in which the host gave the endosymbiont nourishment and protection while the endosymbiont produced ATP through oxidative phosphorylation. The fact that all eukaryotic cells have mitochondria supports this view.

The cell membrane's phospholipid bilayer allows oxygen molecules to move through it. This is because oxygen is a little, nonpolar particle. The correct answer is (A).

Red blood cells, or RBCs, are the erythrocytes. RBCs that are mature and in circulation do not have a nucleus.

The blood transports nearly 70% of carbon dioxide as bicarbonate, 20-25% as bound RBCs, and approximately 7% as dissolved plasma. However, RBCs (as bound to hemoglobin) transport nearly 97% of oxygen, while plasma transports the remaining 3% in a dissolved state.

Biconcave, anucleate, and bright red, erythrocytes lack a nucleus. They are adept at maneuvering the circulatory system due to their concave, smooth, and pliable nature. Hemoglobin is a protein found in red blood cells. Each of the four subunits that make up hemoglobin contains a heme group.

The age range (include ±) during which the first adult (permanent) teeth erupt is 6 to 7 years old.

A child's tooth will usually start to loosen when their adult teeth grow beneath it. The adult tooth pushes the baby tooth out as it erupts. When the root of a tooth begins to break down, it becomes loose. As a result, it will simply fall out and be replaced by an adult tooth. The primary teeth are lost as the child grows, and they are replaced by the permanent teeth.

The roots of the primary teeth are resorbed by the body as the permanent teeth form, causing the primary teeth to loosen and ultimately fall out. The adult teeth then take their place. The first adult teeth to emerge are usually the molars.

The first adult teeth to erupt are the first molars, which are typically found in the back of the mouth. The second molars follow shortly after the first ones. The incisors and canines emerge in the front of the mouth after the molars. In conclusion, the age range (include ±) during which the first adult (permanent) teeth erupt is 6 to 7 years old.

Answer:

Because they are farther away

Explanation:

The given differential equation is:dy/dt = y² + The bifurcation value is the value of a for which the number and stability of equilibrium solutions change.

The equilibrium solution is given by the equation:dy/dt = 0⇒ y² + a = 0⇒ y = ± √(- a)

So, the equilibrium solutions are y = + √(- a) and y = - √(- a).

The sign of the root is determined by the initial conditions and the direction of the phase line.

The bifurcation occurs when a = 0. When a < 0, there are two real equilibrium points.

When a > 0, there are no real equilibrium points, but the phase line has two directions of arrows going toward infinity.

When a = 0, there is only one equilibrium point at y = 0. At this point, the direction of arrows on both sides of the equilibrium is towards the equilibrium.

Thus, the bifurcation values for the one-parameter family are a = 0.

Answer:

In order to be a carrier, the male must be a carrier of the allele without expressing it phenotypically. This can only happen when the inheritance is autosomal because he has a pair of autosomic chromosomes meanwhile he only has one X chromosome. So when the inheritance is X-linked, the allele of the X chromosome will always be phenotypically expressed

The capacity of the southern right whale species that is most severely diminished by the bottleneck is the ability to remain genetically stable and maintain a diverse gene pool.

A genetic bottleneck is a reduction in the size of a population that leads to a loss of genetic diversity. This can occur due to a number of factors, including natural disasters, disease outbreaks, or human activities such as hunting or habitat destruction. In the case of the southern right whales, the population was severely reduced by whaling activity in the 19th and early 20th centuries, leading to a genetic bottleneck. The capacity of the species that is most severely diminished by the bottleneck is the ability to maintain a diverse gene pool, which is necessary for the species to adapt to changing environmental conditions and respond to new challenges. When a population experiences a genetic bottleneck, the number of different genes available for selection is reduced, leading to a loss of genetic diversity. This can make it more difficult for the population to adapt to new challenges and can increase the risk of extinction.

Both are processes that are the result of stem cell division

Explanation:

Self-renewal and differentiation are the property of the stem cells. Both the processes result from stem cell division. Thus, option A is correct.

Stem cells are the special cells that can produce other types of cells from differentiation. For example, the Hematopoietic Stem Cells give rise to the blood cells that can be RBC, WBC, etc.

Differentiation is the process where the less specialized cells give rise to a more specific cell type. The stem cells also undergo self-renewal where the same cell type is also produced.

The hormone that enhances myocardial contractility is epinephrine.

Epinephrine, also known as adrenaline, is a hormone and neurotransmitter released by the adrenal glands in response to stress or stimulation of the sympathetic nervous system.

It acts on the heart by binding to specific receptors called beta-adrenergic receptors in cardiac muscle cells.

When epinephrine binds to these receptors, it stimulates a signaling cascade that results in an increase in intracellular calcium levels. This increased calcium concentration enhances the contractility of the myocardium (heart muscle), leading to stronger and more forceful contractions.

Oxytocin is primarily involved in uterine contractions during childbirth and the release of milk during breastfeeding. Prolactin is responsible for milk production.

Somatotropin (growth hormone) plays a role in regulating growth, metabolism, and other physiological processes but does not directly enhance myocardial contractility.
