There can be a lot of factors that express sexuality. The origin would be its genes. The genetic make-up of the person what trait has passed on to an individual from his parents. Another factor is the environment. A person's sexuality can be influenced by social groups, home environment and from the media that he/she looks at.
Answer:
Neighboring cardiac muscle cells in the walls of heart chambers have specialized cell-to-cell contacts that electrically and mechanically link the cells together, permitting the immediate passage of muscle impulses. These cell-to-cell contacts are called <u>intercalated discs.</u>
Explanation:
Intercalated discs can be described as unique structures present between the cardiac muscles of the heart. The intercalated discs play a major role in making the cardiac muscles contract in a rhythm so that the heart can pump blood in a regular fashion and it hence regulates the effective functioning of the heart. The intercalated discs are the structures that join on cardiac muscle to another and is involved in the transmission of chemical messages between them.
Answer:
The correct answer will be options A, B and E.
Explanation:
Red blood cells or RBC or erythrocytes are the cells present in the connective tissue which forms the blood. RBC perform various functions in the body but the primary function is the transport of the gases in the body.
The RBC are continuously formed in the bone marrow region of the bone form the hemopoietic stem cell found in the bone marrow. These cells produce a large amount of RBC that is about 2 million cells per second in a healthy adult.
When RBC are formed posses nucleus but when mature, they lack nucleus that is genetic material and organelles like mitochondria so, they are not able to divide.
These RBC contain haemoglobin in their cytoplasm which shows high affinity to bind oxygen and low affinity to bind carbon dioxide to the iron group of haemoglobin.
Thus, options A, B and E are the correct answer.
If the outer energy level of the atom is , it does not react readily with other atoms.
The atom has it's outer energy level FULL, it doesn't need anymore electrons; so it's not going to bond with any atoms. It needs no more valence electrons to fill its outermost shell.
Answer:
c. AATGGAGTT
d. AATAGAGTC
Explanation:
SNP is a single nucleotide polymorphism. It means that a particular sequence varies among the members of a population with respect to the single nucleotide. The given sequence of the human genome is "AATGGAGTC". The sequence "AATGGAGTT" of option C differs from it with respect to the single nucleotide at the last position (C is replaced with T).
Similarly, the sequence of option D "AATAGAGTC" differs with respect to the nucleotide at position 4 (G in the original sequence is replaced with A). Therefore, these two sequences represent SNP with respect to the given sequence of the human genome.
