Answer: The correct answer is -.

Organism.

Organisms form the fundamental unit of study in ecology.At every level of organization, the unit possess particular structure and performs specific function.

At organism level, the various morphological form, function, behavior, distribution, and adaptations with respect to the environment are studied. They can perform all the life processes by their own that is independently.

The organisms that are genetically related and interbreed belong to same species and together they form population

Levels of organization in ecology include the population, community, ecosystem, and biosphere. An ecosystem is all the living things in an area interacting with all of the abiotic parts of the environment.

Q - Describe the Mitoses with the help of diagram. write its different phares and explain them.

bonufazy [111]

Answer:

Mitosis is a type of cell division in which single haploid cell (n) or diploid cell (2n) divides into two haploid or diploid daughter cells that are same as the parent.

Mitosis occurs in somatic cells of plants and animals. In this cell division, the two daughter cells have the same number of chromosomes as that in the parent cells.

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.

1.Prophase:-

It is the first visible stage in karyokinesis. The chromosomes appear as long coiled threads called chromatids. The chromatin becomes shorter, thicker and visible due to the condensation of DNA. The chromatins are now called chromosomes. Stainability of nucleus increase. Each chromosome starts to splits longitudinally into two sister chromatids. These sister chromatids are attached to each other at the centromere. The nuclear membrane and nucleolus start to disappear and by the end, it will be completely disappeared.

ii. Metaphase:-

Nuclear membrane and nucleolus completely disappears and simultaneously appearance of spindle fibers. Spindle fibers are attached to the centromere of a chromosome. The chromosomes are arranged on the equatorial plane. The process of gathering of chromosomes in equator is called congressional and plate formed is called metaphasic plate.

iii. Anaphase:-

The centromere of each chromosome splits into two sister chromatids and forms two daughter chromosomes. The daughter chromosomes are pulled towards the poles due to the contraction of spindle fibres and stretching of interzonal fibers. During polar movement, the chromosomes show different shapes i.e. J, U, V, L or I shaped in appearance. At the end of anaphase, each pole will get one set of daughter chromosomes. It is the shortest phase and is also known as a migratory phase.

iv. Telophase:- The daughter chromosomes reach respective poles and uncoil and become thin, long and visible. The spindle fibres start disappearing and finally disappear. The nuclear membrane and the nucleolus reappear.

Two nuclei are formed at the end of telophase. Both the nuclei have the same number of chromosome as the parent cell. It is the last visible stage of karyokinetic and is also known as reorganization phase.

It is followed by cytokines or division of cytoplasm.

How are the names of binary ionic compounds determined?

Alexandra [31]

Naming ionic compounds with transition metals isn't too hard either. They arenamed like the binary compounds, with the cation first, then the anion with -ide added to it, but you have to take into account the variations of the metal ions. You do this by adding Roman numerals in parenthesis to the cation.

1. what is the difference between facts theory and hypothesis

ioda

Answer:

1. Fact: Observations about the world around us. Example: “It’s bright outside.”

Hypothesis: A proposed explanation for a phenomenon made as a starting point for further investigation. Example: “It’s bright outside because the sun is probably out.”

Theory: A well-substantiated explanation acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation. Example: “When the sun is out, it tends to make it bright outside.”

3. As a field of science, biology helps us understand the living world and the ways its many species (including humans) function, evolve, and interact. Advances in medicine, agriculture, biotechnology, and many other areas of biology have brought improvements in the quality of life.

5. Its the ending answer/result of the experiment.

this is what i could get, sorry its not all of them

What is the major cause of the decrease in terrestrial vertebraes throughout the world.

garik1379 [7]

Answer:

The big cause in the extinction of many terrestrial vertebrates species is the hunting while the second cause is the habitat change. ... Hence if the habitat change, they are unable to survive and their population size will decrease.
