During mitosis, chromosomes are moved and separated through the use of spindles composed of microtubule structures.
Explanation:
Throughout mitosis, the chromosomes are initial replicated (copied) and so distributed into a pair of new "daughter" cells. They're replicated throughout the S section of interphase, and within the following phases (prophase, metaphase, anaphase, telophase) are organized, separated, and repackaged at opposite ends of the cell, at that purpose the cell divides. The strand of chromosomes split just like the cell throughout the cellular division. They split in half.
Hemophilia is carried on the X chromosome. If it is passed on to a son it came from its mother. If a daughter inherits it it could have came from either parents or even both. If from the father he himself would have been a hemophiliac. Hope this helps.

Answer:
b: many genes code for RNAs that function directly in the cell
Explanation:
<em>The central dogma</em> theory describes the basic framework for gene expression in living organisms. Genetic information from DNA is encoded or transcribed as RNA which then becomes translated as proteins.
The processes that take place for gene to be successfully expressed are;
- Replication
- Transcription
- Translation
<em>Replication</em> is a process whereby DNA makes a copy of itself to be distributed in daughter cells during cell division.
<em>Transcription</em> is the process whereby genetic information in DNA is encoded as RNAs. The RNAs are short-lived as they are quickly utilized in protein synthesis or <em>translation </em>process.
Hence, the RNAs do not function directly in the cells but mere intermediaries in the synthesis of proteins.
<em>The correct option is b.</em>
<u>Answer</u>:
The food containing 200 calorie have less potential energy than the food containing 300 calorie
<u>Explanation</u>:
The potential energy content of a food material is its stored energy content which is in the form of chemical bonds. This energy can be measured through the combustion of food material inside a calorimeter. A calorimeter is an instrument which is used to measure the total calorie content of the food or other biological samples by measuring its heat content. A Calorie is unit of energy which is in form of heat.
The food material containing carbohydrates proteins and fats have energy in form of chemical bonds. On the breaking of bond inside the body, energy is released as in the case of glucose breakdown also known as glycolysis.
The energy released from glycolysis is used to synthesize high energy containing phosphoanhydride bonds. These ATP molecules are a further breakdown in the system to provide energy to the cell to perform various activities.
