Isokinetic is the exercise that is used for therapy
Answer:
Diffusion is the process of small molecules moving from a high concentrated area to a lower concentrated area. For example, in a crowded train station, when a train arrives, people move from the high concentrated area, which is the platform, and move onto the lower concentrated area, which is the trian.
Explanation:
The process of diffusion does not cost any energy, as it happens naturally, and would cost energy to go against it, like trying to go from the train into the platform costs more energy than just going with the crowd into the train. And only small molecules can do this without using energy. Large molecules, like starch, can't do this without using energy.(ATP) hopefully, this helped you, and it would mean a lot to me if you could give me brainliest!
Answer:
A sustainable community fulfills the requirement of present generation and also preserve resources for the future generation
Explanation:
Local residents of any community can be made aware to protect the environment and its resources through the following ways
a) Conducting learned tutorials
b) Making informatory presentations and videos
c) Conducting informative exercises
A community becomes sustainable by adopting the following strategies –
a) Making communities environmentally sensitive by making it energy efficient
b) Reducing pollution and promoting tree plantation and maintenance
c) Using renewable resource of energy and reducing pollution
d) Protecting bio diversity
e) Making communities cleaner and safer
f) Adopting environmentally friendly life style
A sustainable community looks like a well-equipped neighborhood that has efficient design and energy management system. It has adequate space for all essential components of a neighborhood and caters the needs of a newly borne child and also an old age person
Meiosis I
Metaphase I: Homologue pairs line up at the metaphase plate.
Anaphase I: Homologues separate to opposite ends of the cell. Sister chromatids stay together.
Telophase I: Newly forming cells are haploid, n = 2. Each chromosome still has two sister chromatids, but the chromatids of each chromosome are no longer identical to each other.
When the homologous pairs line up at the metaphase plate, the orientation of each pair is random. For instance, the pink version of the big chromosome and the purple version of the little chromosome happen to be positioned towards the same pole and go into the same cell. But the orientation could have equally well been flipped, so that both purple chromosomes went into the cell together. This allows for the formation of gametes with different sets of homologues Diagram showing the relationship between chromosome configuration at meiosis I and homologue segregation to gametes. The diagram depicts a simplified case in which an organism only has 2n = 4 chromosomes. In this case, four different types of gametes may be produced, depending on whether the maternal homologues are positioned on the same side or on opposite sides of the metaphase plate.

In this case, four different types of gametes may be produced, depending on whether the maternal homologues are positioned on the same side or on opposite sides of the metaphase plate.
In anaphase I, the homologues are pulled apart and move apart to opposite ends of the cell. The sister chromatids of each chromosome, however, remain attached to one another and don't come apart.
Finally, in telophase I, the chromosomes arrive at opposite poles of the cell. In some organisms, the nuclear membrane re-forms and the chromosomes decondense, although in others, this step is skipped—since cells will soon go through another round of division, meiosis II^{2,3} Cytokinesis usually occurs at the same time as telophase I, forming two haploid daughter cells.
Meiosis II Cells move from meiosis I to meiosis II without copying their DNA. Meiosis II is a shorter and simpler process than meiosis I, and you may find it helpful to think of meiosis II as “mitosis for haploid cells."
The cells that enter meiosis II are the ones made in meiosis I. These cells are haploid—have just one chromosome from each homologue pair—but their chromosomes still consist of two sister chromatids. In meiosis II, the sister chromatids separate, making haploid cells with non-duplicated chromosomes.
Phases of meiosis II Prophase II: Starting cells are the haploid cells made in meiosis I. Chromosomes condense.
Metaphase II: Chromosomes line up at the metaphase plate.
Anaphase II: Sister chromatids separate to opposite ends of the cell.
Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid.

During prophase II, chromosomes condense and the nuclear envelope breaks down, if needed. The centrosomes move apart, the spindle forms between them, and the spindle microtubules begin to capture chromosomes.The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase II, the chromosomes line up individually along the metaphase plate. In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell.
In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense. Cytokinesis splits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid. In humans, the products of meiosis are sperm or egg cells.
