Answer:
C. Artificial selection
Explanation:
This is artifical selection because it is "the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations". Humans are unnaturally choosing which humans can survive! Hope this helps :D

Describe the means of spread of the diseases given below.
a) Malaria
b) Cholera
c) Pneumonia
Answer:
Malaria-mosqitoes
Cholera- contaminated food and water
pneumoni- cought droplets
Explanation:
malaria-people get malaria by being bitten by an infective female Anopheles mosquito. Only Anopheles mosquitoes can transmit malaria and they must have been infected through a previous blood meal taken from an infected person.
Cholera-The cholera bacteria is passed through feces (poop). It is spread by eating or drinking food or water contaminated by the feces (poop) of an infected person. This occurs more often in underdeveloped countries lacking proper water supplies and sewage disposal.
Pneumonia-The viruses and bacteria that are commonly found in a child's nose or throat, can infect the lungs if they are inhaled. They may also spread via air-borne droplets from a cough or sneeze. In addition, pneumonia may spread through blood, especially during and shortly after birth
What causes the light to refract as it
passes from air to water?
Answer:
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction

what are some Major Characteristics Temperate Deciduous Forest
Answer:
The Temperate Deciduous Forest is a biome that is always changing. It has four seasons: winter, spring, summer, and fall. Constant rainfall and daylight saving hours also contribute.
Explanation:
Temperate deciduous forests get between 30 and 60 inches of precipitation a year, this helps keep the forest lush and green. When it comes to daylight savings in the fall, lack of sunlight can affect photosynthesis and the amount of sun the plant gets. Unlike the amazon forest, the temperate biome goes through all 4 seasons and has plant regeneration in the spring instead of constant vegitation.

Which of the following statement is true about fossil ?
Answer:
there are no statements...
Explanation:
Answer:
Explanation:The deeper you go into the Earth the older the fossils will be. So, in the diagram you have provided we see that fossil #5 is the oldest and fossil #2 is the youngest.
The order of age goes like this (from youngest to oldest):
1. Fossil #2
2. Fossil #1
3. Fossil #4
4. Fossil #3
5. Fossil #5
Therefore, the only correct answer would be that fossil #4 is younger than fossil #3.

Multicellular organisms grow in size by producing more
Multicellular organisms grow in size by producing more cells by the process of mitosis.
What is Mitosis?Multicellular organisms are the organisms which are made up of hundreds or thousands of cells. These organisms grow by the production of new daughter cells through the process of cell division.
Cell division is of two types: Mitosis and Meiosis. Mitosis is an equational division, in which one parent cell divides to form two daughter cells. Mitosis occurs in each and every cell except in the formation of gametes (germ cells).
Mitosis occurs by nuclear division and cytoplasmic division. Nuclear division include four phases which include prophase, metaphase, anaphase, and telophase.

25.Triacylglycerols (also known as triglycerides) make up more than 95 percent of lipids in the diet and are commonly found in fried foods, vegetable oil, butter, whole milk, cheese, cream cheese, and some meats. Naturally occurring triacylglycerols are found in many foods, including avocados, olives, corn, and nuts.
26. having a tendency to mix with, dissolve in, or be wetted by water.A hydrophilic molecule or portion of a molecule is one whose interactions with water and other polar substances are more thermodynamically favorable than their interactions with oil or other hydrophobic solvents. They are typically charge-polarized and capable of hydrogen bonding.
27.Something defined as hydrophilic is actually attracted to water, while something that is hydrophobic resists water.
28.A polar molecule is a chemical species in which the distribution of electrons between the covalently bonded atoms is not even. Polarity is a description of how different the electrical poles of a molecule are. If they are highly different, it can be said that the species is a highly polar molecule.
29.A nonpolar molecule has no separation of charge, so no positive or negative poles are formed. In other words, the electrical charges of nonpolar molecules are evenly distributed across the molecule. ... Polar molecules tend to dissolve well in water and other polar solvents.

Is Salmonella maintaining? Why or why not? Plz help
Answer and explanation:
No, because most people are infected with salmonella by eating foods that have been contaminated by the s-word. Since our society is much more industrialized, we are cleaner when it comes to making food. Salmonella is mostly found in dirtier countries such as third world countries. Obviously, other food-borne illnesses are out there, but salmonella is not as common anymore, since we are improving.
