In most animals, the diploid state of the life cycle is much larger than the haploid state.
<h3>What is life cycle?</h3>
The life cycle of animals is the oscillation of their lives between the haploid (n) or sexual phase and the diploid (2n) or vegetative phase.
The haploid or sexual phase of animals has to do with their gametes. The male animals produce male gametes while the female animals produce female gametes.
During fertilization, the haploid male gamete (n) fuses with the haploid female gamete (n) to form a diploid (2n) zygote. The zygote is what divides mitotically to form the baby and continues to divide to form the adult animal.
For example, in humans, the female gamete is the egg while the male gamete is the sperm. The diploid version of humans is what we see every day.
Thus, when you consider it, you will see that the haploid life cycle of most animals is much bigger than their diploid life cycle.

Answer:
Recessive alleles are usually represented by lowercase letters and require two copies to be expressed
Explanation:
Answer:
Signal transduction is what allows cells to respond to the influences of the environment around them, providing cells with proper growth and normal cell function.
Explanation:
Living organisms have developed a wide variety of complex processes to transmit signals from the outside to the inside to elicit an adequate cellular response. Defects in these molecular pathways can lead to very different disorders, such as diabetes, cancer, and psychotic illnesses. Signal transduction is the process by which a cell converts a certain signal or external stimulus into another signal or specific response, that is, it is the mechanism by which a cell responds to the stimuli it receives from the environment through diffusion. of those signals to its internal compartments. First, a signaling molecule (also called a ligand) needs to activate a specific receptor on the cell's membrane or cytoplasm. Ligand-receptor binding is very specific; they are recognized as a key and a lock. Second messengers are molecules that allow the received signal to be amplified at the intracellular level. The binding of a ligand to the receptor can generate hundreds of second messenger molecules that, in turn, can modify thousands of effector molecules and give rise to different responses. Cells recognize, integrate, and respond to multiple signals from their environment due to signal transduction, providing cells with a normal cell function.
Question 1 The world's population is spread very unevenly. Some spaces are empty or very sparsely populated: we speak of human deserts:
• Cold polar environments are the least populated regions: the ground, frozen permanently, prevents any form of agriculture, the very low temperatures make the habitat difficult.
• The hot or cold desert environments are also not busy: the lack of rain and the strong heat during the day limit the activities of men. The only exceptions are oases.
• The role of relief is more difficult to define. High temperate mountains like the Alps are generally sparsely populated but tropical chains like the Andes have a high population density. However, men have generally settled in the plains, in the valleys (along with the rivers) and on the coasts.
There are also other factors unrelated to land factors that influence population density such as job availability, or even historical factors.
Question 2: Birth rate:
The birth rate (sometimes called the crude birth rate) is the ratio of the annual number of births to the average total population for that year. When the population grows, the contact between people will be more permanent, and it will increase the marriage rate, and thus the birth rate. Age structure:The age structure is a mode of graphical representation of the structure (of age as well as of sex) of a population which constitutes a synthetic image of the past, present and future of the population.When a population resides for a long time in the same place (in favorable conditions, not raising the death rate and without moving), this will vary the age structure by observing an increase in the elderly population.
