Answer:
In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.
Euchromatin is a lightly packed form of chromatin that is enriched in genes, and is often under active transcription. Euchromatin comprises the most active portion of the genome within the cell nucleus. 92% of the human genome is euchromatic.
The genes present in heterochromatin are usually inactive. The genes present in euchromatin are either already active or will be active during growth. Heterochromatin is transcriptionally-inactive. Euchromatin is transcriptionally. (This one here is the difference)
Answer:
<em>The correct option is B) Binary fission maintains genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell.</em>
Explanation:
Genetic continuity can be described as a fact that the daughter cells have the same amount and same type of genome as the parent cell. It includes the transfer of parental traits to children.
Binary fission can be described as a process of division which bacteria divides. Two daughter cells are produced as a result of binary fission. Each daughter cell is identical to the parent cell and hence maintains genetic continuity.
Answer:
b. It is recommended to go long periods of time without eating to loose weight.
Explanation:
Spending long periods of time without eating is not the right thing to do when you want to lose weight. Spending too much time fasting does not guarantee weight loss, and causes serious illnesses that threaten, among other things, the heart.
A recent survey by nutritionist Roberta Cassani of the Institute of Nutrition in Itu, São Paulo state, shows that the greater the number of hours without putting anything in the mouth, does not help anyone lose weight, on the contrary, fasting causes the increase of the circumference of the abdomen.
According to the scientist, the main reason that prolonged fasting is an enemy of the waist is that the meal set up after this period of scarcity is usually an example of caloric and nutritional imbalance - in the research, fasting usually occurred in the afternoon. “When they have access to food, the greedy individual does not make healthy choices,” explains the expert. Being deprived of energy, the body triggers a whole mechanism that favors the binge eating, the result is that the individual gets fat.
