Lawmakers Discuss Methods Of Preventing Pollutants That Could Directly Starta Positive Feedback Loop

Answers

Answer 1

Answer:

A.

Explanation:

A P E X

Answer 2

Lawmakers discuss methods of preventing pollutants that could directly start a positive feedback loop in the area shown in the picture, and this happens due to the ban on the use of chlorofluorocarbons in refrigeration systems that is in Option A.

What are the negative impacts of chlorofluorocarbons on the ecosystem?

The ozone layer is an important component of the atmosphere that protects life on Earth from harmful ultraviolet radiation from the sun, and one of the major threats to the ozone layer is the release of man-made chemicals such as CFCs, which can react with ozone and deplete it, so if the ozone layer is depleted, more ultraviolet radiation can reach the Earth's surface, causing skin cancer, cataracts, and crop damage.

Hence, this happens due to the ban on the use of chlorofluorocarbons in refrigeration systems that is in Option A.

Explanation:

Sodium and potassium ions are essential for muscle contractions of the heart, and the ions are transported using a pump, which obtains energy from the breaking of ATP molecules, this action requires the expenditure of energy, so sodium and potassium ions are transported using active transport.

What is muscle contraction?

Sodium and potassium ions play a crucial role in muscle contractions, including those of the heart, and to maintain the appropriate concentration of these ions inside and outside the cell, the body uses a protein pump called the sodium-potassium pump, which is an active pump. It requires energy to move substances across cell membranes; the pump uses the energy released by the breakdown of ATP molecules to change its shape, transport the sodium and potassium ions across the membrane, and regulate the muscle contraction.

Hence, the ions are transported using a pump, which obtains energy from the breaking of ATP molecules, this action requires the expenditure of energy, so sodium and potassium ions are transported using active transport.

what is the meaning of respiration​

Answers

Answer:

in physiology respiration is the movement of oxygen from the outside environment to the cells with tissues and the removal of carbon dioxide in the opposite direction .. in contrast exhalation is usually a passive process

hope it's helpful

Answer:

The process of breathing.

Explanation:

The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

**Physiological respiration and cellular respiration are not the same. People sometimes use the word "respiration" to refer to the process of cellular respiration, which is a cellular process in which carbohydrates are converted into energy. The two are related processes, but they are not the same.

What is nucleotide base pairing?

There are five types of nucleotide bases adenine, cytosine, guanine, thymidine, and uracil. These divide into two classes of nucleotides pyrimidine and purine nucleotide bases.  Pyrimidines are uracil, thymine, and cytosine whereas adenine and guanine are purine.

In RNA, adenine, cytosine, and guanine are present but thymine is replaced by uracil. Pyrimidine always binds with the purines through hydrogen bonding. Adenine binds with thymine. Cytosine binds with guanine. But when adenine pairs with uracil in RNA.

Therefore, nucleotide base pairing determines the twisting of the DNA strand depending on the type of nucleotide present.

Answer: 1:There are five recognized types of surface mining, each with specific variations depending on the minerals being extracted. These include strip mining, open-pit mining, mountaintop removal, dredging and highwall mining.

2:Refilled/reshaped w/vegetation planted; filled w/water to become a lake; turned into landfill; left open as home for bats or sealed off if underground.

3:Physical characteristics that make a colored stone valuable are color, clarity to a lesser extent (emeralds will always have a number of inclusions), cut, unusual optical phenomena within the stone such as color zoning (the uneven distribution of coloring within a gem) and asteria (star effects).

4:Atoms where the electrons and protons are not equal are called ions. Ions are charged particles. They can be either positively charged ions or negatively charged ions.

5:Molecule is a substance with two or more atoms bonded together such as the oxygen humans breathe (O2). Elements are pure substances made up of all the same atoms such as gold (Au), hydrogen (H), and oxygen (O). Elements all have the same number of protons in their nuclei and can't be broken down.

6:A covalent bond involves electrons being shared between atoms. The most stable state for an atom occurs when its valence electron shell is full, so atoms form covalent bonds, sharing their valence electrons, so that they achieve a more stable state by filling their valence electron shell.

7:A crystal or crystalline solid is a solid material whose constituents are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

Think of an organism you've heard of or read about that has a surprisingly unusual trait or behavior. How is this trait or behavior different from similar organisms? How does it help the organism survive in its environment?

Answers

Answer: The organism with an unusual behaviour that I have read of is the CHAMELEON

Explanation:

Behaviour is everything an organism does in response to changes in its environment. It is basically adaptive, geared mainly to promoting the organism's survival and reproduction. Generally, we associate behavioural adaptations with animals since most behaviour patterns involve movements of various body parts and locomotion. Animals exhibit a variety of behaviour patterns with respect to

--> obtaining food,

--> escape and defence,

-->surviving unfavorable conditions,

--> communication,

--> finding mates and

--> caring for the young.

The CHAMELEON is famous for its rapid colour changes as it moves from a background of one colour to another. It is DIFFERENT from other similar organisms because it can display a variety of coloured patterns to blend with its background.

The colour change exhibited by the chameleons helps the organism to obtain food and survive in its environment. The CHAMELEON simply sits still, unnoticed and when an unsuspecting insect flies by, it flicks out its tongue to catch it.

Answer:

I have heard that black bears are almost entirely vegetarian while many other bears including polar bears are carnivorous. The black is not actually considered friendly but studies have shown that compared to other animals it is quite nice. Studies have shown that the black bear is omnivorous but that it rarely and I mean rarely eats meat. This trait is different from similar species such as polar bears that eat mainly bearded seals. But maybe if they lived in a place that actually grew plants or other vegetarian things maybe it could have also been a vegetarian or even omnivores. The black bear is also considered “nice” researchers have said that when they studied black bears that they aren’t the meanest animals around which I guess is a plus. The black bears mainly live in forests or even sometimes alpines. So being omnivorous or mostly vegetarian may help the organism survive in its environment because there are a lot of plants and other greens that it can eat around the area it stays in. As well as, when it is in the alpines there may be little to no greens so it will resort to meat or fish because it has to feed its cubs or because it is simply just hungry.

Read the question and type out the
mRNA codon that would result. (make
sure to capitalize)

Answers

Answer: Threonine or Thr.

Explanation:

DNA or deoxyribonucleic acid is a molecule containing genetic information that is passed on from one generation to the next. This molecule is transcribed into another molecule called messenger ribonucleic acid or messenger RNA which is used for protein synthesis in the ribosomes. That is, the one that determines the order in which the amino acids of a protein will be joined. Both RNA and DNA have monomers called nucleotides, composed of a sugar molecule (ribose in RNA or deoxyribose in DNA) linked to a phosphate group and a nitrogenous base. The nitrogenous bases can be adenine (A), thymine (T), guanine (G), cytosine (C) and uracil (U) in RNA replacing T.

A codon is a sequence of three nucleotides found in RNA that codes an amino acid. The genetic code describes the relationship between the sequence of DNA bases in a gene and the corresponding sequence of the protein it encodes. Also note that there is base complementarity between DNA and RNA, that is why DNA is used to make RNA. Complementarity is the ability of the nitrogenous bases in the nucleic acid molecule to combine with their complement, Adenine (A) with Thymine (T) in DNA and A with U in RNA; and Cytosine (C) with Guanine (G) joined by hydrogen bridges.

In the figure, a RNA molecule is shown with the bases, showing which amino acid is code by each codon. In the case where there is a mutation and the G is replaced by an A in the codon coding for alanine, the codon would be ACA coding for threonine or Thr.

Read both passages and answer the question.Passage 1: Excerpt of John Muir's "Calypso Borealis"[1] After earning a few dollars working on my brother-in law's farm near Portage [Wisconsin], I set off on the first of my long lonely excursions, botanising in glorious freedom around the Great Lakes and wandering through innumerable tamarac and arbor-vitae swamps, and forests of maple, basswood, ash, elm, balsam, fir, pine, spruce, hemlock, rejoicing in their bound wealth and strength and beauty, climbing the trees, revelling in their flowers and fruit like bees in beds of goldenrods, glorying in the fresh cool beauty and charm of the bog and meadow heathworts, grasses, carices, ferns, mosses, liverworts displayed in boundless profusion.[2] The rarest and most beautiful of the flowering plants I discovered on this first grand excursion was Calypso borealis (the Hider of the North). I had been fording streams more and more difficult to cross and wading bogs and swamps that seemed more and more extensive and more difficult to force one's way through. Entering one of these great tamarac and arbor-vitae swamps one morning, holding a general though very crooked course by compass, struggling through tangled drooping branches and over and under broad heaps of fallen trees, I began to fear that I would not be able to reach dry ground before dark, and therefore would have to pass the night in the swamp and began, faint and hungry, to plan a nest of branches on one of the largest trees or windfalls like a monkey's nest, or eagle's, or Indian's in the flooded forests of the Orinoco described by Humboldt.[3] But when the sun was getting low and everything seemed most bewildering and discouraging, I found beautiful Calypso on the mossy bank of a stream, growing not in the ground but on a bed of yellow mosses in which its small white bulb had found a soft nest and from which its one leaf and one flower sprung. The flower was white and made the impression of the utmost simple purity like a snowflower. No other bloom was near it, for the bog a short distance below the surface was still frozen, and the water was ice cold. It seemed the most spiritual of all the flower people I had ever met. I sat down beside it and fairly cried for joy[6] Oftentimes I had to sleep without blankets, and sometimes without supper, but usually I had no great difficulty in finding a loaf of bread here and there at the houses of the farmer settlers in the widely scattered clearings. With one of these large backwoods loaves I was able to wander many a long wild fertile mile in the forests and bogs, free as the winds, gathering plants, and glorying in God's abounding inexhaustible spiritual beauty bread. Storms, thunderclouds, winds in the woodswere welcomed as friends.Passage 2: William Wordsworth's "I Wandered Lonely as a Cloud"[1]I wandered lonely as a cloudThat floats on high o'er vales and hills,When all at once I saw a crowd,A host, of golden daffodils;[5]Beside the lake, beneath the trees,Fluttering and dancing in the breeze.Continuous as the stars that shineAnd twinkle on the milky way,They stretched in never-ending line[10]Along the margin of a bay:Ten thousand saw I at a glance,Tossing their heads in sprightly dance.The waves beside them danced; but theyOut-did the sparkling waves in glee:[15]A poet could not but be gay,In such a jocund company:I gazedand gazedbut little thoughtWhat wealth the show to me had brought:For oft, when on my couch I lie[20]In vacant or in pensive mood,They flash upon that inward eyeWhich is the bliss of solitude;And then my heart with pleasure fills,And dances with the daffodils.Both passages use the word "lonely" in their first sentence. In a paragraph of 4-6 sentences, explain how each author feels about his loneliness and how nature takes away their loneliness. Use evidence from both texts to support your answer.
