Explanation:

Answer:

Cyclosis- streaming of cytoplasm within a living cell without deformation of the external cell membrane. In some plant cells there is a rapid rotatory cytoplasmic movement, which is limited to the peripheral parts of the cell next to the cell wall; chloroplasts and granules move in this stream.

Plasmolysis is the process of shrinkage or contraction of the protoplasm of a plant cell as a result of loss of water from the cell. Plasmolysis is one of the results of osmosis and occurs very rarely in nature, but it happens in some extreme conditions.

Answer:

In general, your body fights disease by keeping things out of your body that are foreign. Your primary defense against pathogenic germs are physical barriers like your skin. You also produce pathogen-destroying chemicals, like lysozyme, found on parts of your body without skin, including your tears and mucus membranes. In response to infection, your immune system springs into action. White blood cells, antibodies, and other mechanisms go to work to rid your body of the foreign invader. The immune system has a vital role: It protects your body from harmful substances, germs and cell changes that could make you ill. It is made up of various organs, cells and proteins.

Once infected cells have sensed an invading pathogen, they secrete molecules called cytokines and chemokines. These cells are then primed to resist an infection with the invading virus. Cytokines such as interferons activate anti-viral genes in the infected and neighbouring cells.

Microorganisms capable of causing disease—or pathogens—usually enter our bodies through the eyes, mouth, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread, or be transmitted, by several routes.

The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals: Phagocytic cells ingest and destroy all microbes that pass into body tissues. For example macrophages are cells derived from monocytes (a type of white blood cell).

If pathogens do manage to enter the body, the body's second line of defense attacks them. The second line of defense includes inflammation, phagocytosis, and fever.

Answer:None PLEASE MAKE MORE SENSE MY GOSH

Explanation:NONE

Carbon dioxide (CO2) is a greenhouse gas. It is true

Methane is a greenhouse gas. It is true.

As icebergs melt, they cool off the earth, slowing climate change. It is true.

Ocean pollution from trash and oil spills is making climate change worse.It is true.

Factories that burn coal to produce electricity emit (give off) CO2. It is true.

Our increased appetite for meat has increased climate change. It is true.

Climate change can happen naturally, without human activity. It is false.

Wind, solar, and hydroelectric power do not cause climate change. It is false.

Alternative forms of energy tend to be more expensive than burning fossil fuels. It is true.

Fossil fuels has been result of the biological processes as heat and pressure from the Earth's crust that decomposed these organisms into one of the three main kinds of fuel and these are oil which is also called petroleum, natural gas, or coal.

The origin of the fossil fuels has the anaerobic decomposition of the buried lifeless organisms, that containing natural molecules is created through photosynthesis. The conversion from those materials to excessive-carbon fossil fuels commonly require a geological method of millions of years.

Biological methods are defined as the processes that are very crucial for an organism to live, as well as that shape its capacities for interacting with its surroundings. The organic processes has been made of many chemical reactions or the different events that use to concerned within the persistence as well as the transformation of lifestyles forms.

Therefore, Biological approaches either aerobic or the anaerobic which is based upon the environmental necessities of the microbial consortia.

Cohesion: the attraction force between the same type of molecules.

Adhesion: the attraction force between different types of molecules.

Variations in species help them to adapt themselves to that particular environment and give them a chance of survival. For example, thermophilic bacteria are variants that are resistant to extreme temperature. They have a chance of survival in high temperate zones while others die.

Answer:

Explanation:

Pure water is an hypotonic solution that allows for diffusion of water into the cell and the cell will begin to swell.

The movement of water into the cell will make the cell swell but if water is moving outside the cell will collapse and shrink.

The turgor pressure is usually found withing the cell it ensures the movement of solutes when water is taken into the cell, the turgor pressure will increase. When water is taken out of the cell, the pressure will reduce.

Investigation must be trained and experience will be applied in  step 2 in the Investigation.

Scientific investigation is a continuous process of investigation which involve different steps to get the answer of a question by using scientific method.

The basic steps includes Investigators must be as independent, must be trained and experienced, all relevant issues must be identified, sufficiently resourced.

All relevant physical and digital evidence must be identified, collected , stored and examined during experiment, documentation must be secured and reviewed, witnesses must be identified.

The analysis of all the results must be gathered during the investigation must be objective oriented and based solely on the facts.

Explanation:

If the light converges before reaching the back of the eye, this means that the person is nearsighted and has trouble seeing objects that are far away. To correct nearsightedness, the lenses in the person's glasses would need to divert the light before it entered the eye. Therefore, the glasses would have concave lenses.

If the light converges before reaching the back of the eye, it means that the person is suffering from a refractive error known as myopia, or nearsightedness. To correct myopia, the lenses in the person's glasses should be concave, which means they are thicker at the edges and thinner in the center. Concave lenses are designed to diverge light rays, which helps shift the focal point of light farther back so that it falls directly on the retina. By doing so, the glasses help the eyes see distant objects more clearly.

Hence, if the light converges before reaching the back of the eye, this means that the person is nearsighted and has trouble seeing objects that are far away. To correct nearsightedness, the lenses in the person's glasses would need to divert the light before it entered the eye. Therefore, the glasses would have concave lenses.

Answer:

1.) The two gametes found in humans are the sperm and the ova.

2.) Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).

3.) Because the alleles that the mother and the father carry are mixed together in the offspring.

4.) Because it only introduces genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.
