They prescribe it according to the severity of the symptoms; age and weight is also a factor. antibiotics are to be used within a certain time frame to completely kill off or prevent the multiplication of the bacterial infection even if symptoms are not being shown because the bacteria may still be present
Answer:
1 - Deforestation
2 - Industrial Fishing (mass fishing; when industries use those big nets to collect a ton of fish. y’know that Finding Nemo scene?
3 - Global Warming
4 - Poaching
5 - Pollution
Explanation:
Deforestation is destructive to our air quality, as well as the homes of wild life. This can and does causes animals to die, and not enough animals for the greater part of the food chain.
Industrial fishing is harmful to entire environments purely by there being a lack of fish for other animals to eat, as well as a large portion of the worlds fish being now absent because of this mass fishing.
Global Warming is caused by harmful gasses being released into our atmosphere, which is harmful for all life on earth when the earth’s temperatures are being raised.
Climate change in general is bad and caused by humans’ negative impact.
Poaching is illegally hunting animals. This leads to [if not already endangered] wild animals being endangered or extinct.
Pollution can go from anything to littering on the street or beach to industries dumping oil into our oceans, which is harmful for our water supply and all ocean wildlife.
Negligible. The gravitational attraction of a body towards the center of the earth resultsin the same acceleration for all bodies at a particular location, irrespective of their mass,shape or material, and this acceleration is called the
acceleration due to gravity
,
g
. Thevalue of
g
varies from place to place, being greatest at the poles and the least at theequator. Because this value is large, bodies fall quickly to the surface of the earth whendropped, and so it is very difficult to measure their acceleration directly with considerableaccuracy.Therefore, the acceleration due to gravity is often determined by indirect methods – for example, using a
simple pendulum
or a
compound pendulum
. If we determine
g
usinga simple pendulum, the result is not very accurate because an ideal simple pendulumcannot be realized under laboratory conditions. Hence, you will use two differentcompound pendulums to determine the acceleration due to gravity in the laboratory,namely the
Bar pendulum
and the
Kater’s pendulum

Theory
A bar pendulum is the simplest form of compound pendulum. It is in the form of arectangular bar (with its length much larger than the breadth and the thickness) with holes(for fixing the knife edges) drilled along its length at equal separation.If a bar pendulum of mass

oscillates with a very small amplitude

Answer: D) Yeast is a facultative anaerobe, meaning it can use oxygen for respiration, but then switch to anaerobic respiration when O2 is not present, undergoing fermentation, producing alcohol as a byproduct.

Answer:
Mitosis:
- Homologous chromosomes do not pair
- One row of chromosomes line up in the center of the cell
- The cell nucleus divide only once
- Two diploid daughter cells form that are identical to their parental cells
Meiosis:
- Each replicated chromosome pair with its corresponding homologous pair
- Tetrads form, and crossing-over sometimes occur
- Paired homologous chromosomes line up across the center of the cell
- Four haploid daughter cells form that are not identical to their parental cells
Explanation:
There are two principal types of cells in the organism: Somatic diploid cells (2n) that reproduce by the process of mitosis, and germ cells that are diploid reproductive cells in charge of gamete production. These germ cells suffer both mitosis (to form more sexual cells) and meiosis (giving place to haploid gametes, called sperm and egg cells, through the gametogenesis process). Both somatic cells and germinal cells will end their cycle becoming two daughter cells with the same genetic dotation.
Gametes´destiny is to merge in the process of fecundation, during which a new diploid cell called zygote emerges through fertilization. The zygote is a complete cell from the structural point of view that suffer successive mitosis to form the new organism.
- <u>Meiosis</u> is a process by which, from a diploid germ cell (2n), four daughter cells with a haploid chromosome number (n) are produced. Each daughter cell has half of the chromosomes of the original one. There are two phases in meiosis: the first one in which occurs a chromosome´s reduction division, and the second one where the cell suffers a new division, but this one is not a reductive one.
- In the first phase, Meiosis I: Chromosomes condensate and became visible. Occurs crossing-over between homologous chromosomes in the equatorial plane. Crossin-over makes the daughter cells to be genetically different from the original one. After crossing-over, homologous chromosomes get separated again. Then occurs cytokinesis and chromosomes became lax again.
- In the second phase, Meiosis II: Chromosomes condensate again, they join the spindle apparatus and migrate to the equatorial plane. Centromeres divide and each chromatid goes forward to each pole. Once in the poles the chromosomes became lax again and occur cytokinesis.
- Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced. During mitosis, the cell duplicates and then separates. Mitosis occurs in only one phase. In the prophase, it occurs chromosomes condensation and nuclear membrane breaks. During the metaphase, fibers of the spindle apparatus capture chromosomes and take them toward the center of the cell, to the equatorial plane, where they line up. Each chromatid joins with a microtubule of opposites poles. Sister chromatids are held together until they reach the Anaphase, during which other enzymes are activated to break the bonds and separate the chromatids, which migrate to the opposite poles. In telophase, the duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole. Finally, occurs cytokinesis.
