Answer:
The question lacks the illustrative diagram, the diagram has been attached as an image.
The correct answer, according to the picture is A.
Explanation:
All cells undergo division (mitosis or meiosis). Meiosis reduces the chromosomal number of the daughter cells by half. According to the question, The female species of Myrmecia pilosula ant has diploid cells total number of 2 chromosomes.
At the metaphase stage of meiosis I, homologous chromosomes (similar but non-identical chromosomes received from each parent) aligns at the center/equator of the cell called METAPHASE PLATE. This alignment is done when spindle fibres attach to the kinetochores of the chromosomes.
Option A in the diagram depicts this arrangement of homologous chromosomes in the centre of the cell. Note that, each chromosome has replicated to form SISTER chromatids held together at the centromere. These chromosomes will be pulled apart in the next stage (Anaphase).
Option B depicts only one replicated chromosome
Option D depicts separation of sister chromatids (only one chromosome)
Option E depicts separation of sister chromatids of two chromosomes which occurs in the Anaphase of meiosis II
Lifestyle habits that can have a profound influence on health and on physiological age include:
1. Diet: Healthy diet inclusive of green vegetables, sea food, protein rich meat and fruits will lead to a healthy skin and body.
2.Exercise: Improves the immunity and strength of the body muscles.
3.Clothing: Clean and loose fit clothes do not affect the health of the skin. They also do not restrict the flow blood in the body.
4. Drinking water: A habit of drinking a cup of water once in an hour keeps the body hydrated and reduces the chances of getting a headache.
5. Substance abuse: Taking drugs, smoking or excessive alcohol consumption affects the brain and the various cells of the body. They can lead to the development of tumors or cancers in the body.
Answer:
The process that occurs in the structures marked with X is the Krebs cycle (last option).
Explanation:
The Krebs cycle is a process by which energy in the form of ATP is produced from pyruvate molecules obtained by transformation of glucose, which occurs in the mitochondria, marked with X in the diagram (see image).
The mitochondria is a specialized organelle, whose function is the production of energy within the cell. It has a membrane on the outside that allows the passage of proteins, energetic substrate and ions, and inside it crests are formed where the energetic synthesis takes place.

The motion of an object can be changed if a(n) <u>force</u> is applied on the object.
Answer:
The given statement is - false.
Explanation:
Permafrost or gelisol is the type of soil found in the very cold region that has permafrost which is a frozen layer, found on the 2 meters from the surface of the soil. It is found in places like Alaska.
This type of soil is often used as a habitat for wildlife and rich in vegetation lichen, mosses, spruces. Hearty and robust imply "fertile". However, the surface of gelisol is thin and poor.
Thus, The given statement is - false.
