Answer:
cigarettes increase carbon monoxide concentration in the blood and cause irreversible damage to the lungs, the main organ involved in oxygen uptake
Explanation:
Cigarettes contain many harmful chemical substances capable of damaging the airways and small air sacs (alveoli) in the lungs. The main function of the lungs is to take oxygen into the body. During aerobic cellular respiration, oxygen (O2) reacts with glucose to produce ATP, the energy currency of the cell, in a metabolic process that releases carbon dioxide (CO2) and water (H2O) as waste products. Moreover, cigarettes are also known to increase carbon monoxide levels in the bloodstream. This molecule (carbon monoxide) binds to hemoglobin and myoglobin in the blood, competing with oxygen to be correctly delivered into tissues, thereby producing hypoxia and decreasing cellular respiration rate.
What role does the hypothalamus play in regulating blood glucose levels
Answer:
The ventromedial hypothalamus is a crucial nexus in the initiation of the glucose counter-regulatory response which is partially mediated via glucagon release by the pancreas. The arcuate nucleus of the hypothalamus is preferentially implicated in fine-tuning insulin release

Which statement best explains why different portions of the Moon are visible at different times of the month? *
1 point
As Earth moves along its orbit, it blocks different parts of the Moon.
As the Moon moves along its orbit, it passes through Earth's shadow.
As the Moon moves along its orbit, only a fraction of it is visible from Earth
As Earth moves along its orbit, its shadow falls on different parts of the Moon
Answer:As the Moon moves along its orbit, only a fraction of it is visible from Earth
Explanation:
The different portions of the Moon are visible at different times of the month as as the Moon moves along its orbit, only a fraction of it is visible from Earth.
What is moon orbit ?
The moon travels across the Earth in an elliptical orbit, a barely stretched-out circle. When the moon is closest to Earth, its rotation is slower than its adventure via space, permitting observers to look an extra eight tiers at the jap side.
Different quantities of the moon are seen at special instances of the month due to the location of the moon in its orbital path. From Earth, we're in reality viewing the sun's rays being pondered off diverse quantities of the moon's floor all through its orbit.

The illustration shows one of the ways resources are removed from the deep sea. Describe what type of resources these are, including if they are renewable or non-renewable. Predict two consequences to the seafloor life if this process is not regulated.
Answer:
Marine mining is a process that can be done by dredging the seabed and is used for the extraction of mineral resources from the seabed, which are non-renewable, with a negative impact on marine ecosystems.
Explanation:
The illustration shows a process of marine mining by dredging, where the resource extracted is of a mineral nature, like copper, zinc, silver and gold. Gravel used for construction can also be extracted from the sea. Mineral resources extracted from the sea are not renewable.
The process of marine mining can be harmful to the ecosystems there, so it must be a process that requires control and management from the ecological point of view.
Two possible consequences of not regulating marine mining are:
Destruction of the habitat of life forms present on the sea floor, which endangers many species and even forces migration to more stable areas, with consequences on the food chains. Extinction of marine species that inhabit the seabed. The flora and fauna of the sea floor usually have slow reproductive cycles and, in the case of fish, spawning takes place on the bottom of the sea. Mining endangers the reproductive cycles of the species, leading to induced extinction.Responsible and controlled mining activity can be useful for humans, while avoiding negative consequences on the ecosystems that exist at the seabed.

Answer:
This question is asking to do the following:
Replicate the DNA sequence
Transcribe the complementary DNA into mRNA
Translate the mRNA codons into amino acid sequence
Give the function of mRNA
Please find the detailed answer to this question below
Explanation:
- DNA replication is a process whereby the content of DNA (genetic material) is doubled i.e. duplicated. In other words, another copy of DNA is made from one a DNA template. The principle of DNA replication follows the complementary base pairing rule i.e. A-T, G-C
Original DNA template- A T G G G T C T A G C G A A A G A T
After DNA replication-
Complementary DNA strand- T A C C C A G A T C G C T T T C T A
- Transcription is the process whereby a DNA template used to synthesize a mRNA strand. In this case, the complementary DNA sequence above will be transcribed into a complementary mRNA sequence. Note that Uracil replaces Thymine in RNA.
Complementary DNA strand- T A C C C A G A T C G C T T T C T A
After transcription
mRNA strand- A U G G G U C U A G C G A A A G A U
- Translation is the process by which a amino acid sequence is synthesized from a mRNA sequence. The sequence of the mRNA is read in a group of three bases called CODON. Each codon specifies an amino acid. In this case; the mRNA sequence is A U G G G U C U A G C G A A A G A U
After translation using the genetic code, the amino acid sequence is:
Methionine- Glycine- Leucine- Alanine- Lysine- Aspartic acid
Note:
AUG codes for Methionine (Met)
GGU codes for Glycine (Gly)
CUA codes for Leucine (Leu)
GCG codes for Alanine (Ala)
AAA codes for Lysine (Lys)
GAU codes for Aspartic acid (Asp)
- mRNA, which means messenger RNA, is a type of RNA molecule whose major function is to transport genetic information out of the nucleus into the cytosol in order for translation to take place. In contrast to DNA, which is a storage molecule, mRNA is a transporting/carrier molecule that encodes genetic information.

The options are;
A) biology; theory of relativity
B) geology; theory of continental drift
C) ecology; discovering new elements
D) astronomy; developing quantum mechanics
Answer:
B) geology; theory of continental drift
Explanation:
Looking at the options;
-theory of relativity is a topic in physics originated by Einstein. Thus, it is matched to physics and not biology.
- theory of continental drifts are related to plate tectonics where it explains how continents shift position on Earth's surface. This is a branch of Geography and is thus correctly matched.
- discovering new elements is a topic under chemistry and not ecology. Thus, this is not matched correctly.
-developing quantum mechanics is a topic in physics that deals with the relationship between energy and matterwith respect to atomic and subatomic scale. Thus, it is not well matched.
Therefore correct answer is option B

Which of the following shows a correct base pairing in DNA?
OA and G
OG andc
OCand A
OT andG
Answer:
the correct base pairing in DNA is G and C.
Explanation:
The pyrimidine cytosine(C) always pair with purine guanine(G)
The one that is showing correct base pairing in DNA is G and C. The correct option is B.
For DNA to be stable and maintain its integrity, the proper base pairing is essential. Adenine (A) pairs with thymine (T), and cytosine (C) couples with guanine (G), according to the base pairing laws.
As a result, the base pairing in DNA represented by G and C is correct. The two strands of the DNA double helix are kept together by the hydrogen bonds that form between the bases.
While cytosine and guanine make three hydrogen bonds, adenine and thymine only form two.
The correct replication and transcription of DNA as well as the generational transmission of genetic information are all made possible by this complimentary base pairing.
Thus, the correct option is B.

What are the advantages and disadvantages of anaerobic fermentation?
Answer:
- Advantages: doesn't need oxygen, it is faster than aerobic metabolism
- Disadvantages: less energy is produced for every molecule broken down
Explanation:
Anaerobic fermentation (also known as acid lactic fermentation) is a group of O2-independent metabolic reactions where glucose and other sugars are converted into energy (especially ATP, the energy currency of the cell) and lactic acid. This metabolic pathway occurs in types of bacteria and specific animal cells (for example, muscle cells). In contrast to aerobic respiration, the amount of energy produced by the anaerobic pathway is much smaller because it does not involve ATP production by the Krebs cycle or electron transport chain (the aerobic pathway generates up to 38 ATP molecules per glucose, while the anaerobic pathway produces only 2 ATP molecules per glucose). Moreover, anaerobic fermentation produces lactic acid that may be absorbed by the liver (too much lactic acid may have harmful effects). Finally, it is also important to note that the anaerobic pathway is faster than aerobic metabolism.

Dolphin fins and shark fins: _________
a. are probably built by different genes.
b. are an example of divergence.
c. suggest these two populations could interbreed.
d. are evidence that adaptive evolution is mainly driven by random forces.
e. None of the above is correct.
Answer:
a. are probably built by different genes.
Explanation:
Although sharks and dolphins are aquatic animals belonging to the vertebrate group, sharks are fish while dolphins are mammals. Sharks belong to the class Chondrichthyes which are fish that have a cartilaginous skeleton. On the other hand, dolphins are mammals (class Mammalia) which are animals mainly characterized by the presence of mammary glands. In consequence, both species are not closely phylogenetically linked, thereby those genes involved in the development of the integumentary system (skin) in both species are expected to be different.
