What happen when the process of meiosis does not takes place?

If there has no process of meiosis takes place chromosome number will be doubled disturbing the genetic make up of the organism. If no meiosis has been takes place then the resulting of the zygote will be of double the number of the chromosomes. The genetic makeup would change entirely. The process of the meiosis halves the number of chromosomes in haploid cell and maintain the serenity of organism.

The process of the meiosis due to crossing over, genetic variation occurs which let the offspring receive favourable alleles to survive in new conditions and in the diploid organisms first the gametes are formed, then fertilization occurs and the diploid cell has  formed which gives rise to the organism having diploid cells.

Therefore, Two populations live in the same habitat and compete for food. The first group has larger and multiplies through asexual reproduction the second reproduces sexually an environmental change that causes the larger but unadaptable species to die off.

Matter is anything that has mass and takes up space. It includes molecules, atoms, fundamental particles, and any substance that these particles make up. Matter can change form through physical and chemical changes, but through any of these changes matter is conserved.

In other words, matter doesn't change into a different substance in a physical change. ... Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.

It is technically possible, if and only if, both parents have AO and BO blood.

Explanation:

The statement that describes a positive feedback loop is as follows: when blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugar concentration to a normal level.

What is positive feedback loop?

A positive feedback loop is a feedback loop that occurs in nature when the product of a reaction leads to an increase in that reaction.

A negative feedback loop, on the other hand, occurs when increased output from the system inhibits future production by the system.

Therefore, the statement that describes a positive feedback loop is as follows: when blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugar concentration to a normal level.

Greenhouse effect is the natural heating of the Earth's surface due to the fact that the sunligth waves may penetrate the atmosphere and reach the solid surface, but when the sunlight waves return after reaching the solid surface, process that changes the wavelength of the sunlight, they cannot penetrate the greenhouse gases and so the heat is kept inside the atmosphere with the consequent increase of temperature.
