DNA is often compared to a twisted ladder. In this analogy, what forms the
rungs of the DNA ladder?
A. Pairs of nitrogenous bases
B. Pairs of nucleotides
C. Pairs of sugars
D. Pairs of phosphate groups
The pairs of nucleotides result in the twisting of strands. Therefore, option "B" is correct.
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.

How can one use a community in teaching the concept "Safe use of agro-chemicals" to grade six level?
Answer:
A community can be divided into groups, where each group can present the correct ways to use agro-chemicals safely in different types of activity.
Explanation:
Using a community can be very helpful in teaching the safe use of agrochemicals. This is because, as a community usually has a large number of people, these people can be divided into small groups that will serve as small workshop rooms. Within these groups, the different ways to use agro-chemicals in a safe way, both for the applicator and for the environment, will be shown. Information on the composition of agrochemicals, first aid in case of accidents with the use of these products, among other things, can also be presented.
Which is an endocrine function?
Answer:
Explanation:
The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems. In humans, the major endocrine glands are the thyroid gland and the adrenal glands. The study of the endocrine system and its disorders is known as endocrinology.

Answer:
Cell
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.

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?
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)
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.
what is the meaning of respiration
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.
