Answer:

What does that mean? :)

Explanation:

DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.

The instructions stored within DNA are read and processed by a cell in two steps: transcription and translation. Each of these steps is a separate biochemical process involving multiple molecules. During transcription, a portion of the cell's DNA serves as a template for creation of an RNA molecule. (RNA, or ribonucleic acid, is chemically similar to DNA, except for three main differences described later on in this concept page.) In some cases, the newly created RNA molecule is itself a finished product, and it serves an important function within the cell. In other cases, the RNA molecule carries messages from the DNA to other parts of the cell for processing. Most often, this information is used to manufacture proteins. The specific type of RNA that carries the information stored in DNA to other areas of the cell is called messenger RNA, or mRNA.

How does transcription proceed?

Transcription begins when an enzyme called RNA polymerase attaches to the DNA template strand and begins assembling a new chain of nucleotides to produce a complementary RNA strand. There are multiple types of types of RNA. In eukaryotes, there are multiple types of RNA polymerase which make the various types of RNA. In prokaryotes, a single RNA polymerase makes all types of RNA. Generally speaking, polymerases are large enzymes that work together with a number of other specialized cell proteins. These cell proteins, called transcription factors, help determine which DNA sequences should be transcribed and precisely when the transcription process should occur.

You feel exhausted when your body is oxygenally depleted. When your lungs are unable to breathe in and out properly, fatigue sets in more quickly.  Thus, option A is correct.

Necrosis, or cell death, occurs when glucose and oxygen are not provided to cells. It's interesting to note that cells can survive hypoxia.

According to the early research showing that acute oxygen deprivation triggers the intrinsic apoptotic pathway, there is a reduction in the potential of the mitochondrial membrane.

This starts a nasty loop. You're less likely to exercise when you're feeling tired as a result of a lack of oxygen.

Therefore, Numerous factors, such as a reduction in red blood cell concentration or a reduction in hemoglobin's oxygen saturation, can lead to a reduction in oxygen-carrying capacity.

Answer:

Yes, protons are pumped across the membrane, but flow right back again through the ATP synthase.  More important is that illumination is required for carbon fixation.  As photosynthesis runs, the chloroplasts remove CO2 from the water they are suspended in.  In solution, CO2 forms carbonic acid, so removing CO2 will reduce the level of carbonic acid, raising the pH.

Explanation:

Chloroplasts are the primary cell organelles involved in the conversion of light energy into stable chemical energy through photosynthesis. The chloroplasts will become alkaline due to a rise in pH and a reduction in carbon dioxide.

Chloroplast is the green-colored cell organelle, primarily involved in the conversion of light energy into chemical energy.

When the isolated chloroplasts are illuminated, the suspension in which chloroplasts are suspended becomes alkaline. It is assumed that protons are pumped in from the medium to the thylakoids.

As photosynthesis takes place, the chloroplasts remove carbon dioxide from the suspension, which causes an increase in the pH of the suspension.

Therefore, the formation of carbonic acid from the CO2 will raise the pH.

Explanation:

Answer:b

Explanation:

The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N  the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.

The net force acting on the bicycle is:-

F net = Total force acting on bicycle

In above question,

Given the F1 = 150 N and F2 = -84 N (Negative sign shows that force is acting opposite to the motion)

So,

Fnet = F1 + F2

Fnet = 150 N -84 N

Fnet = 66 N

Now the acceleration will be

Fnet = mass X acceleration

In above question,

Fnet = 66 N

Mass = 100 Kg

So,

Acceleration = Fnet/Mass

Acceleration = 66/100

Acceleration = 0.66 m/sec^2

Therefore, The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N  the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.

Answer: Rosalind Franklin discovered the density of DNA and, more importantly, established that the molecule existed in a helical conformation. Her work to make clearer X-ray patterns of DNA molecules laid the foundation for James Watson and Francis Crick's suggestion that DNA is a double-helix polymer in 1953.

Explanation:

Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.

She was one of the greatest scientists who made significant contributions to the field of DNA by using X-ray crystallography, and apart from that, she also made contributions to the field of virology. As X-ray diffraction facilitates the study of the structure of viruses such as the tobacco mosaic virus and the polio virus and helps in understanding the replication of viruses, it is also helpful in the study of the structure of coal and other carbon-based materials.

Frozen raindrops that hit the earth's surface are known as sleet (Ice Pellets). When sleet first forms, snow will be the precipitation that falls upwards. Thus, option C is correct.

Both sleet and freezing rain develop using the same fundamental mechanism: liquid droplets in a layer of warm air above the surface descend into a layer of freezing air close to the ground.

When snowflakes fall through a thin layer of warm air, they only partially melt, resulting in sleet.

These slushy drops then refreeze as they fall through a thick layer of icy air above the surface, and when they finally make it to the ground, they do so as frozen raindrops that bounce as they hit the ground.

When rain falls through a chilly layer and directly on the ground, it freezes on contact and forms a layer of ice. This is known as freezing rain.

Therefore, Snow that falls from a cloud and melts as it passes through an upper layer before falling back through a lower layer below freezing is known as sleet.

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the diagram illustrating the growth chamber. However, since insects also produce/exhale carbon dioxide (CO₂) as a waste product, the level of CO₂ in the growth chamber will increase since insects will serve as an additional source for the production of CO₂.

This model shows how carbon is been cycled though the earth's systems. The CO₂ released/exhaled by animals is been inhaled by plants and used for the production of food substance like glucose (through the process of photosynthesis). Animals eat these plants and then release carbon from these food sources as CO₂ which is taken up from the environment again by plants.

- Controls the entry of chyme into the duodenum: A. Pylorus

- Controls the entry of chyme into the colon: H. Ileocecal valve

- Substance that helps make or break a chemical bond: I. Enzyme

- A component of gastric juice: G. Hydrochloric acid

- Organ that releases bile into the small intestine: E. Gallbladder

-  Organ that synthesizes bile: J. Liver

- Fingerlike projection of small intestinal lining: D. Villus

- Absorption mechanism that requires energy: B. Active transport

- Absorption mechanism that does not require energy: C. Diffusion  

- Carries fat-soluble vitamins: F. Lymphatic system

Explanation:

The pylorus is a part of the digestive system that connects the stomach to the duodenum. The ileocecal valve is a muscle localized between the ileum of the small intestine and the colon, whose main function is to limit the reflux of colonic contents. Gastric juice is a liquid consisting of hydrochloric acid, lipase, and pepsin, whose main function is to inactivate microorganisms. The gallbladder is a small organ that in combination with the small intestine are reservoirs for bile acid and regulate the biliary secretion of this acid. The bile acid is a fluid secreted by the liver that helps to digest lipids in the small intestine. Intestinal villi (villus in singular) are finger-like projections that increase the surface area for the absorption of nutrients in the small intestine. Active transport is the movement of molecules across cell membranes by using energy from ATP hydrolysis or by using an electrochemical gradient. Diffusion is the movement of molecules across cell membranes from a side of the membrane with higher concentration to the other side with lower concentration. An enzyme is a molecule (generally a protein) that is capable of accelerating the rate of a chemical reaction. Fat-soluble vitamins are absorbed in the small intestine and then they are transported through the lymphatic system to be released into the bloodstream.
