Answer:
(a)The strength of natural fibers is very less as compared to synthetic fibers. Natural fibers are heavy in weight. Natural fibers can be damaged by moths and other insects. These fibers are not wrinkle-free. These fibers are not long lasting and hence not durable.
(b) Cellulose is termed as polymer because it is made up of many monomer units.
(c) Rayon is first man- made fibre it is known as artificial silk because it have properties that are similar to silk.
(d) Rayon possesses many properties of natural fibers since it is a semi-synthetic fiber. Nylon is a synthetic fiber and has properties that are completely different from natural fibers. The key difference between rayon and nylon is their resistance to wrinkles and tears.
(e) Nylon has since become a popular choice, as it has excellent wind resistance, good elasticity, mildew resistance, and is comparatively cheaper. The material is also lightweight and dries quickly.
(f) When the piece of cotton is burnt then it burns completely and produces no odour or smell. When nylon is burnt, It completely burns and produces burning paper like odour. When nylon is burnt then the nylon is completely shrink and starts to melt first and then produces odour during the time of burning

What are chromosomes?Chromosomes are defined as a thread like structure located in the nucleus of every cell in our body and are formed of tightly coiled DNA surrounding proteins.
Chromosomes plays very important role in human body.
The primary purpose of chromosomes is to transport DNA and genetic information from parents to offspring.
It play a vital role during cell division.
They keep DNA from becoming twisted and damaged.

What happens during S phase?
O A. Chromosomes are duplicated.
O B. DNA separates into two nuclei.
O C. The cell splits in two.
O D. Cytoplasm is manufactured.
Answers
Answer: A. Chromosomes are duplicated.
Explanation: This is the correct answer on the quiz.
Chromosomes are duplicated in S phase. Therefore, option (A) is correct.
What do you mean by S phase?
Between G1 phase and G2 phase, DNA replication takes place during S phase of the cell cycle. The processes that take place during S-phase are tightly controlled and highly conserved.
The cell replicates its genetic material entirely during the S phase of DNA synthesis; At the end of S phase, a normal diploid somatic cell with a DNA complement of 2N acquires a DNA complement of 4N.
DNA synthesis or replication occurs during the S phase of the cell cycle, which occurs prior to the interphase. Before entering mitosis or meiosis, the cell's genetic material is replicated in this manner, leaving enough DNA for daughter cells to divide.

In meiosis, sister kinetochores are attached to the same pole of the cell during meiosis I, and sister chromatid cohesion is released during anaphase II. What would be the likely result if sister kinetochores were attached to different poles of the cell during meiosis I and sister chromatid cohesion was released during anaphase I
Answers
Answer:
sister chromatids would migrate to opposite poles in anaphase I
Explanation:
Kinetochores are multiprotein structures that establish the attachment of spindle microtubules to the chromatids during cell division (either mitosis or meiosis). Sister chromatid cohesion at the centromeres refers to the mechanism by which sister chromatids are paired and held together during meiosis I. This process (sister chromatid cohesion) is fundamental to ensure the correct orientation of chromatids on the spindle microtubules and their subsequent segregation in meiosis II. The fusion of sister kinetochores in meiosis I underlies sister chromatid cohesion during this stage of the cell division, thereby their disruption or destruction of sister chromatid cohesion would lead to separation and segregation of sister chromatids to opposite poles of the cell in anaphase I.

All of its cells are electrically connected via gap junctions. All of its cells are sparsely distributed in the extracellular matrix.
Answers
Answer:
Connective tissue is a group of tissues in the body that keep the body and its organs in shape while also providing cohesion and internal support.
All of its cells exist sparsely distributed in the extracellular matrix is the best description of connective tissue.
What is connective tissue?
Tissue that sustains, protects and provides structure to other tissues and organs in the body. Connective tissue also stores fat, permits the movement of nutrients and other substances between tissues and organs, and allows the repair of damaged tissue. Connective tissue exists created up of cells, fibers, and a gel-like substance.
Connective tissue is discovered in between other tissues everywhere in the body, including the nervous system. The three outer membranes (the meninges) that surround the brain and spinal cord exist composed of dense inert connective tissue.
Connective tissues bind systems together, form a framework and support for organs and the body as a whole, store fat, transport substances, defend against disease, and assist restoration of tissue damage.

Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three "dominant" capital letter genes (A, B and C) control dark pigmentation because more melanin is produced. The "recessive"alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced.

Here, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.
What is Punnett Square?The Punnett square is a tool used to predict the probability of offspring inheriting specific alleles from their parents. If all of the offspring exhibit the same phenotype (such as purple flower color), it is likely that the parents both carried at least one dominant allele for that trait. This would mean that the purple flower color allele is dominant. Here, the parents are both purple and white, so all the offspring are dominant in nature.
Hence, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

Answers
Answer:
Between depths of tectonic plate boundaries and the outer core.
Explanation:
The rate of temperature increases below the Earth's surface is greatest between depths of tectonic plate boundaries and the outer core. At the depth, some of the heat comes from the Earth's core while most of the heat comes from decay of radioactive elements, mainly uranium, thorium and potassium that is located in rocks of the crust. So we can say that the the increase in temperature with depth varies with the chemical composition and age of the rocks.
