to understand what the result of these crosses would be like, we need to know what is gene
<h3>Gene</h3><h3 />
The gene is a strand of a DNA molecule (deoxyribonucleic acid), which carries the characteristics that are genetically inherited. They are composed of a sequence of DNA and RNA (ribonucleic acid), responsible for the production and synthesis of proteins in the cell. The gene's greatest attribution, therefore, is to be a store and transmitter of information.
Genes can be classified into:
- Dominant genes: assume the specific characteristic in the offspring;
- Recessive genes: manifests itself in the absence of the dominant gene;
- Structural genes: are those that contain the information that will determine the structure of living beings;
- Operator gene: acts on the functioning of other genes;
- Regulatory gene: responsible for controlling the synthesis and transcription of other genes.
<h3 /><h3 />
in genetics, are individuals who have pairs of genes that are identical or different alleles. This means that while the has two identical genes alleles, with the beings the opposite happens, since they have two different genes alleles.
with this information we can say that a white and short plant, when crossed with a plant for both traits, has 60% of this plant being with expression of the dominant genes and 40% of being with expression of the recessive gene.

If a particular job of a cell was to swim a long distance to an egg with a flagella, then it would need more mitochondria. As mitochondria undergo cellular respiration and essentially utilize the carbohydrates for that particular cell to produce the final product of ATP high energy containing molecules needed for the movement.
Answer:
<h3>Yes, Passive transport can occur in dead cells.</h3>
Explanation:
For passive transport to occur, a concentration gradient has to be formed across a permeable or semi-permeable membrane. If the cell membrane of the dead cell, which is a semipermeable membrane, is intact and a concentration gradient has formed on both sides, passive transport can occur.
A concentration gradient is the difference in the concentration of solute molecules across the membrane. Passive transport will allow solute molecules to travel from the higher concentration of the solute to the lower concentration across a membrane till equilibrium is reached, that is, both the sides of the membrane has equal concentration of the solute.
The transport of the solvent can occur as well, from higher concentration to lower concentration.
Answer:
The Bay of Pigs invasion
Explanation:
The Bay of Pigs invasion was an attempt of Cuban exiles to destroy the government of Fidel Castro. These were actions of the USA aimed against Cuba. This invasion was one unsuccessful try and shame for the regime of Kenedy. This was an example of a group decision that was unsuccessful. Ths attempt provoked many side effects, as entering of Cuban-Americans in the Congress of America.
Answer:
1: Population; 2: Biome;3: Ecosystem
Explanation:
Population refers to the number of people in a state. Biome is a large area characterised by it's vegetation, soil,climate, and wildlife. Ecosystem is a geographic area where plants, animals and other organisms exists
