Answer:
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation (such as after tree-felling in a woodland) and destructive events such as fires.
Answer:
Freshwater biomes are large areas consisting of plants and animals grouped around water with "less than 1% salt concentration." This includes lakes, rivers, ponds, streams, and some types of wetlands.
Answer:
Valine-Leucine-Proline-Lysine-Histidine
Explanation:
The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.
N.B: Thymine is replaced by Uracil in the mRNA
For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU
Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)
Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).
GUG specifies Valine amino acid
CUG specifies Leucine amino acid
CCU specifies Proline amino acid
AAG specifies Lysine amino acid
CAU specifies Histidine amino acid
Answer:
Gene pairs segregate randomly and independently of each other.
Explanation:
Genes are the basic units of hereditary and are located on chromosomes. According to Gregor Mendel's law of independent assortment which states that the alleles of two (or more) different genes are sorted into gametes independently of one another. This means that the allele a gamete receives for one gene does not influence the allele the same gamete receives for another gene.
For example, in a the pea plants used by Mendel in his studies, the genes for seed shape and flower color were inherited independent of each other by the offspring of the parent pea plants. Therefore, Mendel concluded that the inheritance of each trait was independent of the other.
The use of electronic instruments or other techniques to monitor and change subconscious activities, many of which are regulated by the autonomic nervous system, is called biofeedback.
<h3>What is biofeedback?</h3>
A mind-body approach known as biofeedback employs a variety of monitoring tools to give the body's physical functions, which are typically controlled by the body's automatic systems, conscious control. There are several kinds of biofeedback instruments that can be used to track the development of the activity and show the efficacy of the therapy as it is being administered.
The equipment that measures the following uses biofeedback the most frequently:
- brain activity
- respiration rate
- blood pressure
- heartbeat frequency and heartbeat variability
- tension in muscles
- electrification of the skin
- skin temperature
Devices used to measure body change are:
- Electromyogram (EMG): To measure muscular tension, use this.
- Electrodermal activity (EDA): This measures variations in perspiration rate.
- Measures of finger pulses: These evaluate heart rate and blood pressure.
- Electroencephalogram (EEG): This is used to assess brain electrical activity.
