Answer:

Although RNA polymerase must recognize sequences on the template strand, by convention we draw the DNA sequence and regulatory signals on the "mRNA-like" strand. (This makes it simpler to directly determine the sequence of the resulting RNA.) The upper strand of DNA is the "mRNA-like" strand.

The following statements are true of the urinary system: Option D. Ureters transport urine from the kidneys to the urinary bladder. Ureters are tubes that transport urine from the kidneys to the urinary bladder .

The urinary system is a collection of organs that work together to produce, transport, and expel urine from the body. Here are the multiple-choice options, followed by the correct answers:

Option A: The renal pelvis is responsible for filtering blood - FALSE. The renal pelvis is responsible for collecting urine and transporting it to the ureters.

Option B: The dense irregular connective tissue that surrounds the kidneys is the renal capsule - TRUE. The renal capsule covers the kidneys and provides support.

Option C: The distal convoluted tubule directly connects to the ureters - FALSE. The distal convoluted tubule is part of the nephron and empties into the collecting duct, which then connects to the renal pelvis and ureters.

Option D: Ureters transport urine from the kidneys to the urinary bladder - TRUE. The ureters are tubes that connect the kidneys to the bladder and transport urine.

Option E: The kidneys help to regulate blood pressure - TRUE. The kidneys are responsible for filtering blood and removing waste products, but they also play a role in regulating blood pressure and fluid balance. They do this by producing hormones that help control blood pressure and by adjusting the amount of water and electrolytes that are excreted in urine.

Explanation:

A group of living things that can interbreed to generate fertile offspring and share specific physical and genetic characteristics is referred to as a species in biology. Understanding the diversity of life on Earth and how various organisms are related to one another requires a knowledge of the idea of species.

Historically, physical characteristics that could be observed, like as morphology, behaviour, and ecology, were used to categorise species. However with the development of molecular genetics, species definitions have been broadened to incorporate genetic data. In reality, genetic data is frequently used to support or challenge conventional species designations, particularly when physical characteristics are inconclusive.

It is crucial to remember that the idea of a species is not always clear-cut, and there are several discussions and arguments around how to identify and categorise species. For instance, some experts contend that under specific conditions, various species may be able to interbreed to create fertile offspring, while others contend that the idea of a species is merely a human construct used for classification and communication, rather than a basic unit of nature.

Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.

Explanation:

The sun’s gravitational pull extends to all 8 planets by the The Sun's gravity pulls the planets in orbit round it, and a few planets pull moons in orbit round them.

A planet's orbital pace changes, relying on how a long way it's far from the Sun. The nearer a planet is to the Sun, the more potent the Sun's gravitational pull on it, and the quicker the planet movements. The farther it's far from the Sun, the weaker the Sun's gravitational pull, and the slower it movements in its orbit.

Even spacecraft are in movement via the sun system, both in orbit across the Earth or Moon, or touring to similarly worlds, due to gravitational forces.

The total body energy is the sum of energy ingested minus the energy used, plus stored energy.

Here, correct option is D. Stored energy.

In other words, the total body energy is the net energy balance of our bodies. This net energy balance is determined by the energy we consume from our food, the energy we expend in activities such as exercise, and the energy our bodies produce in the form of heat. Our food contains energy in the form of calories.

Our bodies use this energy for all of our activities. When our bodies are at rest, we produce energy in the form of heat, known as resting metabolic rate. In addition, the energy we consume that is not used is stored in the form of fat and glycogen, which can be used later when needed.

An important clue to the structure of DNA was provided by an X-ray diffraction photograph of DNA. Thus, the correct option is B.

X-ray diffraction (XRD) is a widely used technique to assess the crystallinity and structure of the solid samples such as biomolecules like DNA and proteins. The crystal X-ray diffraction phenomenon results from the scattering process in which the X-rays are scattered by the electrons of the atoms which are present in the sample without any change in the wavelength.

Rosalind Franklin's X-ray diffraction method patterns of the DNA molecules rendered the important clue from which DNA has the structure of a double helical structure. The most famous X-ray photograph, the Photo 51 is still printed in most of the Biology textbooks.

The mechanism by which a particle is transported downstream is a primarily function of particle size and fluid velocity.

D is the correct answer.

The erosion, movement, and deposition of sediment as a result of currents and waves is known as sediment transport. Physical, chemical, and biological factors may have an impact on these systems, further complicating the system and making it more challenging to explain sediment dynamics.

The movement of a load downstream during sediment transport depends on water flow. Water flow is unpredictable and is impacted not only by the local topography (such as slope), but also by the water level, which is in turn affected by precipitation (or a lack thereof). The majority of variations in water level are caused by weather phenomena, such rainfall.

It could be this one -

BUT...

The other one says limitted resources.

The description that shows the competition in an environment is three organisms battling over limited resources. Thus, option D is correct.

It has been a natural interaction between two or more same or the different organisms for the same resources just like food, shelter, or light, substrate etc. This type of interaction shows an effect on the fitness between two competitive organisms.

The major factor that influencing the competition are considered as the density of the individuals and the number of the organisms. The competition has one of the major driving that forces for the evolution and  it has involve in the adaptation of the species which is according to the changing environment.  

On the basis of the taxonomy, as well as the competition of the species can be interspecific and intraspecific, which is similarly on the basis of the mechanism it has been divided into interference, exploitative and apparent competition.

Answer:

1.They act as a catalyst

2.Enzymes are proteins

3.They are affected by Ph

4.They are affected by temperature

Explanation:

1.Enzymes act as a catalyst because they either speed up or slow down the rate of a reaction

2.They are proteins because they are made up of 20 amino acids

3.Enzymes are affected by temperature, if the temperature increases, the reaction rate increases. However if the temperature continues to increase, the shape of the active site changes.If the temperature is below preffered temperature range,the rate of the reaction becomes slower,but the shape is not denatured.

Answer:

Yes, they are very much the main cause of severe storms because the heat molecules get into the atmosphere and clouds, causing chemical reactions and damage. At some point in time, the energy built up, as well as the damage done, must undo itself. This is done through a storm. It is the environment's way of cleaning itself.
