Answer:
The question is not well structured, the correct one is;
Look at the following statement. What word completes the second gap? Substances move by active transport from an area where they are __________ concentrated to an area where they are __________ concentrated
The answer is MORE
Explanation:
Substances move from one position to another in living systems. This movement of substances can either be passive (without energy) or active (require energy). Active transport of substances involves the movement of substances against their concentration gradient.
Ideally, substances move naturally from an area they are more concentrated to an area they are less concentrated but in active transport, the opposite occurs i.e. substances move from area that they are less concentrated to one that they are more concentrated, which is going up against the normal concentration slope/gradient. Due to this, energy in form of ATP is usually required by the cell to perform active transport unlike passive transport that occurs without energy input.
Exanples of active transport in living cells are exocytosis and endocytosis in some organisms. Based on this explanation, the first gap will be LESS while the second gap will be MORE.
Details about Neurotransmitters are described below.
Explanation:
1.Neurotransmitters are referred to as the body’s chemical messengers. They are the molecules used by the nervous system to transmit messages between neurons, or from neurons to muscles.
2.Terms in this set
- acetylcholine. A neurotransmitter used by neurons in the PNS and CNS in the control of functions ranging from muscle contraction and heart rate to digestion and memory.
- norepinephrine.
- serotonin.
- dopamine.
- GABA.
- glutamate.
- endorphin.
3.Neurotransmitters are made of the following :
- The amino acid neurotransmitters glutamate, GABA (γ-aminobutyric acid), and glycine. All of these are amino acids, though GABA is not an amino acid that's found in proteins. ...
- The biogenic amines dopamine, norepinephrine, epinephrine, serotonin, and histamine, which are made from amino acid precursors.
4.Neurotransmitters can impact a specific area of the brain, including behavior or mood, their malfunctions can cause effects ranging from mood swings to aggression and anxiety. ... Understanding the way neurotransmitters function in the brain could lead to better treatments for mental disorders.
The provided question is incomplete as it lacks the image required to identify the, however the correct image is attached:
Answer:
B is protein
C is the process of translation
Explanation:
The given image is a flow chart representation of the process of the protein synthesis from the DNA molecule by a two-step process that is combinedly known as the central dogma.
The first step is a transcription in which an RNA molecule (mRNA) is synthesized from the DNA molecule in organism nucleus (in eukaryotes only). The second step is to making a polypeptide chain of amino acid with help of rRNA, tRNA, and mRNA, this process is known as translation and represented in the image as C and B is the protein that formed.
Thus, the correct answer is - B is protein
C is the process of translation
Answer: DNA
Explanation:
A chromosome is a thread-like material with a long structure found in the cell nucleus. It mainly contains DNA and proteins. Due to the presence of DNA in chromosomes, it carries several genes.
The total number of chromosomes in human cell is 46: 44 are non-sex chromosomes while 2 are sex chromosomes
