Answer:
A protein with its amino-terminus in the cytoplasm and its carboxy-terminus in the extracellular space. (Ans. A)
Explanation:
Integral membrane protein (IMP) is defined as a membrane protein molecule which is directly attached to the biological membrane known as phospholipid bilayers. All transmembrane proteins are integral membrane protein but not all integral membrane protein are transmembrane proteins.
Integral membrane proteins function as a transporter, receptors, channels, proteins which is responsible for cell adhesion, proteins are also Involved in transduction and build up of energy.
Membrane proteins are class according to their transmembrane domain properties. The N-terminus of an integral membrane protein type I is in the endoplasmic reticulum lumen, where N-terminus of an integral membrane protein type II in the cytoplasm.
Answer:
genetics;the study of heredity and the variation of inherited characteristics.
evolution;evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection
variation;a change or difference in condition, amount, or level, typically with certain limits
Explanation:
The haploid number of the chromosomes should be 32.
Diploid number means that they have the complete sets of chromosomes in their cells, these cells are usually found in somatic (body) cells and different organisms have a different number. For example, a human somatic cell has 46 chromosomes, such as a muscle cell, or a skin cell etc.
Meanwhile, haploid number means that the number of chromosomes in the cell only have half of the chromosome number than that of the diploid cells. These haploid cells are usually found in gametes of sexually reproducing organisms, such as human, we have 23 chromosomes in our sex cells. This is important because we have to make sure the chromosome number of offsprings are not doubled, as during sexual reproduction, male and female gametes fuse together to form a zygote.
Therefore, to calculate the haploid number of a cell, we can divide the diploid number by 2, which is 64/2, and the answer would be 32.
Answer:
A higher amount of carbon dioxide in the atmosphere leads to higher global temperatures, which then results in thermal expansion of seawater and melting of glaciers and ice sheets.
Explanation:
Answer:
"Forests transport large quantities of water into the atmosphere via plant transpiration. When deforestation occurs, precious rain is lost from the area, flowing away as river water and causing permanent drying."
