Circulation to and from the lungs is referred to as
Answer:
pulmonary circulation
Explanation:
The pulmonary circulation moves the blood between the lungs and heart. Since the blood carries oxygen the heart pumps it to every body part including the lungs so we can maintain homeostasis.
Why does a cell need a LOT of surface area compared to their volume?
Answer:
The surface area to volume ratio (SA:V) limits cell size because the bigger the cell gets, the less surface area it has for its size.
Explanation:
This is important if you are a cell that depends on diffusion through your cell wall to obtain oxygen, water, and food and get rid of carbon dioxide and waste materials.
Mutated gene
DNA sequence: TAC-ATA-ACG-CCC-AGC-G
mRNA:
Codons:
Amino acid sequence:
Answer:
mRNA: AUG-UAU-UGC-GGG-UCG-C
Codons: AUG, UAU, UGC, GGG, UCG
Amino acid sequence: Methionine- Tyrosine- Cysteine- Glycine- Tryptophan
Explanation:
This question is trying to illustrate the process of gene expression, which includes transcription (DNA - mRNA) and translation (mRNA - protein). According to this question, a mutated DNA sequence was given as follows: TAC-ATA-ACG-CCC-AGC-G
After transcription, which employs the complementary base pairing rule i.e A-U, G-C, the following mRNA sequence will be produced:
mRNA: AUG-UAU-UGC-GGG-UCG-C
After translation, which uses mRNA codons (a group of three nucleotide bases that encode a specific amino acids), the following amino acid sequence will be produced:
Amino acid sequence: Methionine (Met)- Tyrosine (Tyr)- Cysteine (Cys)- Glycine (Gly)- Tryptophan (Try).
Note that:
AUG encodes methionine
UAU encodes tyrosine
UGC encodes Cysteine
GGG encodes Glycine
UCG encodes tryptophan

Why sometimes, even when we know the danger, we continue to do this matter, for example, you use a sharp tool, You know that it is possible to cut your hand if you continue to use this tool without changing the way you hold it, but sometimes you persist. In the end, you may hurt yourself, and you may be lucky. What makes you persist sometimes?
Answer:
The fact that you have a task set in mind is something that can make you persist. The urge to satisfy your need to finish that task with the sharp tool is what drives you to persist with using the sharp tool knowing what could be the possible outcome of using it.

Which factor can increase the chances of a species evolving by natural selection?
A. high reproductive rate
B. no related species
C. stable environmental conditions
D. small gene pool
Answer:
A.
Explanation:
A high reproductive rate means a larger gene pool, and traits which benefit stand above the rest better, and are kept in the population. No related species would allow for only the small gene pool to continue in a slow evolutionary pace. Stable ecosystem does not generally require an organism to adapt.
The factor that can increase the chances of a species evolving by natural selection is genetic variation. Therefore, option "A" is correct.
What is genetic variation?The difference in the gene sequence can be between interspecies and interindividual. The primary force behind the process of natural selection is genetic variation. Gene variation is the result of different forms of alleles.
The variants which result in genetic alternation are single nucleotide polymorphisms or variation, copy number variation, structural variation, translocation, insertion, deletion, and inversion. These result in the formation of different alleles resulting in genetic variation.
Therefore, genetic variation results in different skin colors, and hair colors.

What is the correct term for the production of specialized sex cells
Answer:
Meiosis
Explanation:
Meiosis is a cell division that takes place in the germ cells. The formation of human gametes is called gametogenesis.
In the process of meiosis, germ cells are formed from diploid, stem cells of spermatogonia and oogonia, ie. male and female gametes containing a haploid number of chromosomes, or half less than somatic ones. The importance of meiosis is reflected in the maintenance of a constant number of chromosomes from generation to generation.

All of the following are correct about alcoholism except:
a) risks of developing alcoholism may be increased by high levels of stress.
b) it tends to run in families, indicating there is a genetic component to the disease.
c) its development is influenced by environmental factors.
d) the older a person is when alcohol consumption begins, the greater the likelihood that a drinking problem will eventually develop.
Answer: D. the older a person is when alcohol consumption begins, the greater the likelihood that a drinking problem will eventually develop.
Explanation:
Alcoholism is a chronic disease that simply means the uncontrolled drinking of alcohol. When someone is faced with alcoholism, such person cannot control his or her drinking.
When someone is stressed, this may lead to the risk of developing alcoholism. It can also be genetic and can be influenced by environmental factors. Its availability and its acceptance by the society could lead to alcoholism.
The correct option is D as age doesn't really have anything to do with the person having a drinking problem. A young person may have a drinking problem likewise an old person.
if the number of birth in a population is the same number of deaths in a population what will happen to the growth of population?
A. It will increase
B. It will decrease
C. It will stay the same
D. It will fluctuate
Answer:
C. It will stay the same
Explanation:
Let's say the population is 7
Then let's say 4 more are born, and since the number of births and deaths are the same then the number of deaths must be 4.
Since the number of births is positive and the number of deaths are negative then they cancel out and the population number stays the same.
Therefore C is correct.
If the number of birth in a population is the same number of deaths in a population, the growth of the population will stay the same. Thus, the correct option for this question is C.
What is Population?A Population may be defined as a group of individuals belonging to the same species living in the same area at a particular time.
The characteristics of the population like size, birth rate, death rate, population dispersion, age distribution, etc. cannot be applied on the individual level. But these factors can be significantly represented on the graph and hence, they are known as demographic factors.
The growth rate of the population can be measured by two factors such as birth rate and death rate. When the birth rate is greater than the death rate, the growth of the population will increase. But when the birth rate is lower than the death rate, the growth of the population will decrease.
Therefore, if the number of birth in a population is the same number of deaths in a population, the growth of the population will stay the same. Thus, the correct option for this question is C.

b. They connot reproduce ouside of a host cell.
c- the must use anzymes ecoded by theviras itself.
d- they invariably kilang cell they infect,
Answer:
b. They cannot reproduce outside of a host cell.
Explanation:
Viruses are parasitic organisms that need a host in order to thrive and reproduce. This means that they cannot replicate outside of a host cell, but can only do this by parasitizing it. They have to find a host cell in order to continue their life-cycle or else they won't thrive. The word "obligate" means being restricted to a specific mode or function in life. This shows that the virus has a restriction when it comes to reproduction. It cannot reproduce without finding a host cell.

Which of the following outcomes will most likely result from the irreversible binding of GDP to the G protein?
Answer:
The correct answer is - The intracellular concentration of glycogen will increase.
Explanation:
The intracellular concentration of glycogen will increase as the result of the irreversible binding of GDP to the G protein due to the not respond to the binding of norepinephrine to the beta-adrenergic receptor which prevents the separation of the G protein alpha subunit.
This leads to the activation of adenylyl cyclase. PKA will be lesser and glucose 1 phosphate as the dissociation of G protein will not take place and ultimately to glycogen accumulation.
The most likely result from the irreversible binding of GDP to the G protein results in an increase in intracellular concentration of glycogen.
G proteins are a group of proteins that operate as signaling molecules inside cells, conveying signals from various external stimuli to the cell's core. They govern their signaling cycle with the help of GDP.
In an irreversible binding of GDP to the G protein, the G protein is rendered inactive.The GDP is swapped by GTP to initiate the protein, and the G protein then sends out its signal.This results in an increase in the intracellular concentration of glycogen because of the non-response to norepinephrine binding and to the beta-adrenergic receptor, which inhibits the G protein alpha subunit from being separated.
