C. put it a glass of room temperature water
D. break it into pieces and warm up the pieces
Answers
Answer:i think it C srry if im wrong
Explanation:
Answer: It’s A
Explanation:
It you hold the cube in your hand it will melt because of the body heat. If you break the pieces and warm them up, it will melt. If you put it in a glass of room temperature water, the water would absorb the cold and it will melt. But if you put it in an insulated container, it will keep the cold in hence it will not melt the fast.

A. Identical twins have different DNA, and fraternal twins have different DNA.
B. Fraternal twins share the exact same DNA, but identical twins do not.
C. Identical twins and fraternal twins share the exact same DNA.
D. Identical twins share the exact same DNA, but fraternal twins do not.
Answers
Answer:
D. Identical twins share the exact same DNA, but fraternal twins do not.
Explanation:
Identical twins are the twins formed from one egg provided by their mother and one sperm provided by their father. In contrast, fraternal twins are formed from two different sperms and two different eggs from the same father and mother.
Due to the fact that identical twins are as a result of one fertilized egg dividing into two, they share the same exact DNA. On the other hand, fraternal twins do not share the same exact DNA because they are formed from separate eggs and separate sperms.

Which characteristic listed below is most unique to plants?
Select one:
a.
Plants are heterotrophs.
b.
Plants undergo photosynthesis.
c.
Plants are multi-cellular.
d.
Plants are composed of eukaryotic cells.
Answers
Answer:
Plants are composed of eukaryotic cells.
Explanation:
Eukaryotic cells (as opposed to prokaryotic cells) have internal, membrane-bound organelles and a distinct nucleus that physically separates the genetic material of the cell from the all of the other parts of the cell. All protists, fungi, plants, and animals are composed of eukaryotic cells.
The characteristic that is most unique to plants is that they undergo the process of photosynthesis. Thus, the correct option for this question is B.
What is Photosynthesis?Photosynthesis may be defined as a type of process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis is as follows:
[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O.[/tex]Plants are eukaryotic in nature and have a double membrane cell organelle that is known as Chloroplast. These cell organelles have a green-colored pigment known as chlorophyll that captures the sunlight and converts it into chemical form and accomplishes the process of photosynthesis.
Therefore, the characteristic that is most unique to plants is that they undergo the process of photosynthesis. Thus, the correct option for this question is B.

Answers
Answer:

Explanation:
The problem here is to complete the photosynthesis reaction.
During photosynthesis, green plants manufacture their food in the presence of sunlight.
They take inorganic materials from the environment which are the carbon dioxide and water and using sunlight, they produce glucose and oxygen gas.
The reaction expression is given below:
Carbon dioxide + water → Glucose + Oxygen
So;

.
Answers
Answer:
Stem cells have the ability to divide through mitosis and produce unspecified cells. Stem cells can be developed into a required tissue because of their ability of differentiation.
Explanation:
A stem cell is a cell that is in an undifferentiated state. This means that it has not specialized in a specific type that carries out a specific function of that tissue, which does not imply that stem cells do not have their own function. The concept of stem cell is due to the ability to originate specialized cells from one or more tissues, depending on the degree of potency or plasticity it has. They are found in all multicellular living organisms. Their main characteristic is that by reproducing through the process of mitosis (they divide into two cells) they can form more stem cells or differentiate, that is, they become specialized cells, in such a way that they are essential for the renewal of cells in different tissues. and to repair them.
Stem cells have the ability to divide through mitosis and produce unspecified cells. They can be developed into a required tissue because of their ability of differentiation.
Stem cells are a special type of cell that may develop into a variety of specialized cells inside the body. They have the ability to differentiate into more specialized cells through the process of mitotic activity (mitosis) and perform restorative and regenerative roles.
Stem cells have significant and potential treatment for a variety of diseases due to their capacity to repair, regenerate, and grow into certain specialized cell types.

A researcher hypothesizes that in mice, two autosomal dominant traits, trait Q and trait R, are determined by separate genes found on the same chromosome. The researcher crosses mice that are
heterozygous for both traits and counts the number of offspring with each combination of phenotypes. The total number of offspring produced was 64. The researcher plans to do a chi-square
analysis of the data and calculates the expected number of mice with each combination of phenotypes. Which of the following is the expected number of offspring that will display both trait Q and
trait R
Answers
Answer:
Explanation:
If we consider the traits Q and R individually, then
P(Q) = 75% (Q is dominant, from hetero-zygous parents)
similarly
P(R) = 75% (Q is dominant, from hetero-zygous parents)
Assuming the two alleles P & Q are indepedent, then
P(Q and R) = 75% * 75% = 56.25%
Out of 64 offsprings, we expect 75*56.25% = 9/16*64 = 36 express both Q and R traits, on the average.
For the given experiment 36 offspring out of 64 will produce both Q and R traits.
Di-hybrid Cross:
It is cross of organisms in which scientist perform the experiment keeping two traits in mind.
One parent is pure and dominant while another is Heterozygous for traits.
The parental genotypes will be,
RRQQ x RrQq
The gametes will be,
RQ, Rq, rQ, and rq
The cross,
RQ Rq rQ rq
RQ RQRQ RQRq RQrQ RQrq
Probability, If the traits Q and R expressed
P(Q) = 75% (Q is dominant, from heterozygous parents)
P(R) = 75% (Q is dominant, from heterozygous parents)
Probability, if two alleles P & Q are independent, then
P(Q & R) = 75% x 75% = 56.25%
The offspring that express both alleles, out of 64 offspring,
[tex]\bold {75 \times 56.25\% = \dfrac {9}{16\times 64} = 36 }[/tex]
Therefore, for the given experiment 36 offspring out of 64 will produce both Q and R traits.

Explanation:
First level consumer: 1,000 energy units. Second level consumer: 100 energy units. Third level consumer: 10 energy units.
What is trophic level?The group of species in an ecosystem that are at the same level in the food chain is referred to as a trophic level. A food chain has five basic trophic levels, each of which has a different nutritional relationship to the main energy source.
The Sun is any ecosystem's main source of energy (although there are exceptions in deep sea ecosystems). Primary producers, sometimes referred to as autotrophs, receive their energy input from the Sun's solar radiation.
The first trophic level is made up of primary producers. Consumers, also known as heterotrophs, make up the remaining trophic levels; heterotrophs are unable to reproduce.
Therefore, First level consumer: 1,000 energy units. Second level consumer: 100 energy units. Third level consumer: 10 energy units.
