O -The modified RNA molecule is transported into the nucleus.
-Exons are spliced together.
-Introns are not transcribed from DNA to RNA.
Answer:
A small cap of extra nucleotides is added to both ends of the RNA
Hope you like it
Thank you ❤️
The statement 'exons are spliced together' is TRUE. The exons are the coding regions of genes.
RNA splicing is a eukaryotic mechanism by which non-coding sequences of genes called 'introns' are removed from the precursor messenger RNA (pre-mRNA), whereas protein-coding sequences called 'exons' are spliced together.These gene coding sequences (exons) are spliced together by a macromolecular complex known as the spliceosome.In consequence, a pre-mRNA is converted into a mature mRNA, which is subsequently used for protein synthesis.In conclusion, the statement 'exons are spliced together' is TRUE.

He has been struggling to sleep due to the loud noise of police sirens at night, but has noticed that the sirens have been disturbing his sleep less as he gets used to the noise. Which of the following terms best describes what Ricky is experiencing?
a. Sensitization
b. Habituation
c. Operant conditioning
d. Extinction
Answer:
吧b
Explanation:
Ricky has been struggling to sleep due to the loud noise of police sirens at night, but has noticed that the sirens have been disturbing his sleep less as he gets used to the noise. Ricky is experiencing habituation.
What is habituation?habituation is a type of response where complete elimination of a particular response or zero frequency of occurrence occur.
If the stimulus continues for an additional number of trials, although no changes occur but the response will exhibit lower levels of recovery.
Habituation is a non-associative learning in which an automatic decrease in the intensity of a response occur which is repetitive, weak stimulus, without serious consequences, for example, ignoring stimuli
Habituation defines as the fading of the response over the course of monotonous stimulation, and sensitization refers to processes of increased response.

An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone.
True
False
Answer:
The answer is true.. it is attached to the carbon backbone.
The statement "An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone" is definitely true.
What is Unsaturated fat?Unsaturated fat may be defined as a kind of fat carrying a high proportion of fatty acid molecules with at least one double bond. This type of fatty acid is considered to be healthier in the diet than saturated fat.
An unsaturated fat generally contains almost all of the hydrogen atoms which are directly attached to the carbon backbone in a series of systematic arrangements.
Unsaturated fat is typically fatty acid that remains liquid at room temperature and comes from a plant, such as olive, peanut, corn, cottonseed, etc.
Therefore, the statement "An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone" is definitely true.

Inorganic compounds include carbon dioxide, oxygen, water, and most ionic compounds.
True
False
Answer:
[tex]{ \underline{ \sf{true}}}[/tex]
Explanation:
because they chemically decompose
It is true that inorganic compounds include carbon dioxide, oxygen, water, and most ionic compounds.
What are inorganic compounds?Any substance in which two or more chemical elements usually other than carbon are combined, almost always in definite proportions, is an inorganic compound.
When carbon is bound to hydrogen, the compound is classified as organic.
Organic compounds are distinguished by the presence of carbon atoms. Most inorganic compounds do not contain carbon atoms.
Water, sodium chloride (salt), sodium bicarbonate (baking soda), calcium carbonate (dietary calcium source), and muriatic acid are examples of common inorganic compounds (industrial-grade hydrochloric acid).
Inorganic compounds are characterized by high melting points and varying degrees of electrical conductivity.

Hydrogen has an atomic number of one but has no neutrons if a hydrogen atom has a mass of three it would be
Answer:
tritium
Explanation:
a hydrogen atom with:
1 proton 0 neutrons = hydrogen
1 proton 1 neutron = deuterium
1 proton 2 neutrons = tritium
If the hydrogen has a mass of three, then it would be tritium
What it would be?An atom of hydrogen with an atomic number of one and a mass of three would be a hydrogen isotope called tritium.
Regular hydrogen (also known as protium) has one proton and no neutrons, giving it a mass of approximately 1 atomic mass unit (amu). Tritium, on the other hand, has one proton and two neutrons, giving it a total mass of about 3 atomic mass units (amu). This makes tritium a heavier and less common isotope of hydrogen.

Which of the following is/are TRUE about a cell’s plasma membrane? (CHOOSE ALL THAT APPLY.)
Question 3 options:
Plant cells have a cell wall instead of a plasma membrane.
Proteins are embedded in the plasma membrane and contribute to its function.
The exterior of a phospholipid bilayer is hydrophilic, and the interior is hydrophobic (see figure above).
The plasma membrane regulates the movement of molecules and ions into and out of the cell.
Answer:
The plasma membrane regulates the movement of molecules and ions into and out of the cell.
Explanation:
Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes have a specialized structure that facilitates their gatekeeping function.
The true statement about a cell’s plasma membrane is that the plasma membrane regulates the movement of molecules and ions into and out of the cell. The correct option is D.
What is a plasma membrane?The plasma membrane or cell membrane is the outer covering of the cell. It is made up of lipids and proteins. Cell membranes serve to separate and group cells. Every cell has an exterior plasma membrane that controls both what and how much of any given material enters the cell.
Eukaryotic cells, unlike prokaryotes, have internal membranes that enclose their organelles and regulate the exchange of vital cell components. Both kinds of membranes have a unique structure that makes it easier for them to perform the gatekeeping job.
Thus, the correct option is D. The plasma membrane regulates the movement of molecules and ions into and out of the cell.

The DNA sequence AGGCTTCGCGAAGGTAAC would code for the sequence of 6 amino acids.
True
False
Answer:
True
Explanation:
Amino acids are coded from the DNA sequence in groups of three bases, that is, three bases (three letter codes) also called codon codes for (or specifies) an Amino acid.
in the above DNA sequence each of the prospective 6 Amino acids will each require a triplet of bases. Thus, the simple calculation of 6×3 yields 18. Thus we need at least 18 bases in our DNA sequence, barring stop codon, to code for Amino acids.
Counting, the above DNA sequence contains 18 bases exactly.

explain the disadvantage in terms of energy loss when humans eat beef rather than legumes
Answer:
Katha Ko Bajja Muchi Ko Chora
The main disadvantage in terms of energy loss when humans eat beef rather than legumes is the inefficiency of energy transfer.
When humans consume beef, they are consuming meat from animals that have themselves consumed plant-based foods. However, energy is lost at each step of the food chain. Plants capture energy from the sun through photosynthesis and convert it into organic compounds.
When animals consume plants, only a fraction of that energy is transferred to the animal's tissues, as some is used for metabolic processes, movement, and other functions.
Therefore, when humans consume beef, they are indirectly obtaining energy from plants but at a much lower efficiency. If humans were to consume plant-based foods directly, such as legumes, they would bypass the energy loss that occurs in the conversion of plant energy to animal energy. Legumes are protein-rich plant sources that can provide comparable amounts of nutrients and energy without the same level of energy loss.
By opting for legumes instead of beef, humans can have a more efficient and sustainable use of energy resources, reducing the environmental impact associated with livestock production and utilizing plant-based sources more directly.
