What is a mixture in which all the components are evenly spread out?
Answer:
A mixture is made when two or more substances are combined, but they are not combined chemically. There are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures. In a homogenous mixture all the substances are evenly distributed throughout the mixture (salt water, air, blood).

What is the second step of the scientific method ?
which method of heat transfer is what caused the green house effect on earth
Answer:
Radiative transfer
Explanation:
The greenhouse effect is a phenomenon of radiative transfer, the process by which the energy of light waves is exchanged in matter. Radiative transfer dictates what energy is reflected, absorbed, and emitted.
Which of the following items is NOT found on the periodic table?
a) the atomic number of each element
b) the date that each element was discovered
c) the name of each element
d) the atomic mass of each element
Answer:
b
Explanation:
In farmland areas poor drainage can lead to a buildup of salt in
water supplies. A student performed an investigation to study the
effects of salinity on the germination rates of seeds. The student
places seeds in several solutions containing 0% to 3% salt. The
data from this investigation is shown below and suggests that
increased salinity in more areas may lead to a decrease in which of
the following?
Answer:
food production.
Explanation:
food plants need water to survive. Salt soaks water from a source of it If the slat buildup occurs in that water supply then the plants will not have anything to use to get their glucose to make food. This then leads to the con of the plants dying and the people having a loss of food production.

A beaker of with 115 mL of solution has a temperature of 21 °C. The solution contains 5 g of salt and 115 mL of water. Students added two ice cubes to the solution and stirred the solution with a stirring rod. Which properties of the solution changed as the ice cubes melted?
Answer:
Properties of the solution which changed
1. The temperature of the solution
2. The concentration of the solution
Explanation:
The properties of the solution that changed are:
1. The temperature of the solution: Once the ice cubes were added, (we will assume that the ice cubes were at 0 degrees Celcius) The system had to attain thermal equilibrium. Hence, the higher temperature of the solution melted the ice, while the ice, cooled the entire mixture.
2. The concentration of the solution reduced. We need to remember that ice is water. As the ice was added, we were indirectly adding more water to teh solution, thus diluting its concentration

what on the blood determine a person’s blood type.
Blood types are determined by the presence or absence of certain antigens – substances that can trigger an immune response if they are foreign to the body. Since some antigens can trigger a patient's immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching.

How do natural pollination and artificial pollination differ
Answer:
Natural pollinators, like bees, pollinate flowers randomly, essentially mixing up their genomes and increasing genetic diversity. This leads to different types of future plants. However, artificial pollination is so labor intensive, it's hard to replicate the same variety in pollination.Aug 8, 2017
Explanation:
Artificial pollination is the type of pollination carried out by humans. It is a mechanical technique used to pollinate plants when natural pollination is insufficient or undesirable. It does not require the help of insects or weather.
Natural pollination consists of the transfer of pollen between the male and female organs of the flowers, without human intervention. In other words, pollen is transferred from the stamens to the stigma of the flowers, where it fertilises the ovules, making seed and fruit production possible.
7. The synthesis of which molecule(s) could be affected by the mutation of DNA?
A. mRNA only
B.Proteins only
C.Both MRNA and
D. neither mRNA nor proteins
Answer:
mRNA
Explanation:
usususussussssa
The synthesis of ; ( C ) Both mRNA and proteins could be affected by the mutation of DNA
The formation of mRNA occurs in the nucleus via the synthesis of a nucleotide sequence of DNA ( transcription ) while the synthesis of proteins is directed by the mRNA.
Therefore any mutation of the DNA will have a direct effect on the synthesis of Both mRNA and Proteins.
Hence we can conclude that The synthesis of Both mRNA and proteins could be affected by the mutation of DNA.

Mendel's Experiments
Mendel studied several different traits of a pea plant. For example, some pea plants have purple flowers and others have white flowers. Pea plants can either self-fertilize or cross-fertilize. Crossing two plants is called hybridization.
