Spontaneous generation is the idea that new living organisms can form from nonliving matter. Cell theory, however, states that cells
can only grow from other cells.
Which of the following experimental results supports the idea that new cells can only form from other cells?
A. A plant cell had its cell wall broken, and the cell was found to no longer be able to function.
OB. A piece of uncovered meat that was left outside contained maggots by the end of one day.
OC. A container of soup that was heated and sealed did not grow mold even after several months.
OD. A mold sample examined under a microscope showed a regular structure made of many individual cells.

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.

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.

Answer:

If the color differences were less distinct (ex. all butterflies were only shades of reds and oranges), would you expect similar results? ... That the predator has the ability to associate the prey to the sickness, and that the predator can distinguish the color difference.

Explanation:

The predator has the ability to associate the prey to the sickness, and that the predator can distinguish the color difference.

The Viceroy's color pattern has been evolved because the natural selection favoured them. The viceroy butterfly camouflage as the monarch butterfly as well as the exhibit Mullerian mimicry where as these two toxic species has the mimic each other for their benefit and by time natural selection has been favoured these.

Natural selection has been the process by which the reproductively fitest has the populations of the living organisms survive, adapt and change. The viceroy butterfly has the brush-footed butterfly having the dark orange colour with the black veins and row of the white spots on the border of its wings.

Monarch butterfly has the same as that of the viceroy except that it has the black horizontal stripes that has cross the bottom of its back wings. Species has refers to the group of the organisms which have the similar features and which are able to be interbreed to produce the viable and the fertile offspring.

Therefore, reproductive isolation prevents interbreeding between members of different species. It includes a collection of behavioral, evolutionary, and physiological processes.

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.

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.

Answer: The chemical reaction for the digestion of fats is when A triester is produced through the chemical reaction of three fatty acid molecules with glycerol, a molecule that contains three hydroxyl groups. When fats are broken down these fatty acid chains and glycerol are free for the body to use.

Explanation:

Lipids (fats and oils)

Lipase enzymes break down fat into fatty acids and glycerol. Digestion of fat in the small intestine is helped by bile, made in the liver. Bile breaks the fat into small droplets that are easier for the lipase enzymes to work on. Bile is not an enzyme.

The nitrogen cycle seems to be the nitrogen form of recycling, that requires fixing of nitrogen, Teodoro mamoncillo, nitrogen removal, and deionization. The mechanism whereby the nitrogen and nitrites are subsequently converted to nitrogen fixation is denitrification. 

Answer:

Less complex.

Explanation:

Glucose is both a monomer and simple sugar.

Glucose is a monosaccharide. It is a biomolecule. It is less complex than the rest of the biomolecules, such as proteins, lipids, and other complex carbohydrates like glycogen.

Biomolecules are present inside the cell. Carbohydrates, proteins, and lipids are some examples of biomolecules. Carbohydrates are divided into monosaccharides, disaccharides, and polysaccharides.

A monosaccharide has a single unit. Examples are glucose, fructose, etc. A disaccharide consists of two units. An example is maltose. Maltose is made up of two units of glucose connected by a glycosidic bond. An example of a polysaccharide is glycogen. Multiple sugar units are connected by glycosidic bonds to form glycogen. It is a storage product.

Carbohydrates are present on our cell surface as peptidoglycan. Protein is a biomolecule that is made up of amino acid monomers. They make the different structures of a cell, such as actin fibers, etc. Lipid is made up of hydrogen and carbon. Examples are cholesterol, phospholipids, etc.

Hence, in comparison to all other biomolecules, glucose is the simplest.
