Molecules (DNA) that contain the information that determines eye color are passed from parents to children.
Parents pass there genes to there offspring which helps in determining there phenotype.What are genes?A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. Many genes do not code for proteins.What are proteins?A protein is a naturally occurring, extremely complex substance that consists of amino acid residues joined by peptide bonds. Proteins are present in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies.

1.The illustration below shows that sexual reproduction involving two parent pea plants resulted in the production of four offspring.
A. All four offspring received all of their genetic information only from Parent 1 and are therefore identical to that parent
B. All four offspring received all of their genetic information only from Parent 2 and are therefore identical to that parent.
C. All four offspring are genetically unique and did not receive any of their genetic information from either parent.
D. Each of the offspring is genetically unique and received some of its genetic information from each parent, so each has some traits in common with each parent.
Answer:
C
Explanation:
Because of the x and y chromosomes and they split apart and that's how you get 4 offspring.
The fusion of two different gametes leads to the formation of new offspring is called reproduction. There are two types of reproduction that is sexual and sexual.
The correct option is A
The branch of biology which deals with the study of genes is called genetics. there are two types of alleles that give all the character to the phenotypes. The dominant allele is the allele that suppresses the recessive allele and shows its effect.
In question, the F1 generation shows only one type of character which belongs to parent 1 because that is the dominant allele.
Hence, the correct option is A that is all four offspring received all of their genetic information only from Parent 1 and are therefore identical to that parent

please mark me as brainlist
The process of taking gaseous carbon dioxide or oxygen by leaves is termed peristomal diffusion or diffusion through stomata present on leaves.
Plants take up carbon dioxide or oxygen from the air through their leaves as they have several stomata on their surface. The small holes or openings in the underside of the leaf are called stomata.
Diffusion through stomata also helps oxygen, produced in photosynthesis, to leave the leaf.The diffusion of gaseous carbon dioxide or oxygen is proportional to the concentration difference between the atmosphere and leaves.The loss of water vapor in transpiration also occurs through stomata.peristomal diffusion or diffusion through the leaves allows the gaseous exchange.Thus, the correct answer is - peristomal diffusion or diffusion through stomata present on leaves.

A farmer decides to test whether or not a fertilizer will make her crops grow bigger. In year 1, she plants corn in two different fields on her property and fertilizes one and not the other. She measures the height of 10 corn plants in meters from each field. She takes her measurements every week for three months. In year 2, she puts irrigation in one of the fields and conducts the same experiment.
Required:
a. What is the independent variable and the treatments (increments) used in the experiment?
b. What is the dependent variable and the units in which it was measured?
c. Name at least two controlled variables:
d. What is the hypothesis?
e. Identify two sources of error in the first year in the experiment:
f. Identify two sources of error in the second year in the experiment:
Answer:
a. independent variable: the fertilizer.
treatments: the use of fertilizer in one of the fields.
b. dependent variable: the crop growth in height.
units: meters
c. two controlled variables: soil pH / solar-radiation exposure, and water supply
d. hypothesis: the fertilizer makes the crops grow bigger.
e. two sources of error in the first year:
the researcher might plant the two crops under different conditionstake wrong measures of the height of the cornsf. two sources of error in the second year:
she can fail in irrigating the crops climatic and environmental conditions might change and have different consequences on each of the fields (this source affects the results influencing the growth of the plants).Explanation:
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. These changes allow analyzing its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the fertilizer is the independent variable. Treatments: Refers to the experimental procedure applied in the experimental group. In this example, the use of fertilizer is the treatment. Here the experimental group (the one that receives the experimental procedure, with changes in the independent variable) is the fertilized field. Data from the experimental group is compared with the data from the control group, to analyze the effects of the fertilizer.Dependent variable: The values of these variables respond to any change in the independent variable. It represents the quantity of something. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. In the exposed example, the crop growth rate in height is the dependent variable, that depends on the fertilizer used in that field. The units in which the crop is measured are meters in height. Controlled variable: Refers to those variables equally applied to every group or subject in an experiment and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example, soil pH and solar-radiation exposure can be two controlled variables, as they must be equal for both fields. Water supply by irrigation ducts during the second year in both fields is also a controlled variable. Hypothesis: A hypothesis is a possible answer for a question, a speculation that is not verified yet and requires corroboration. A hypothesis must express what is expected to occur in a perfectly comprehensive manner. It must be objective and directly related to variables. In this example, the hypothesis might be that the fertilizer makes the crops grow bigger. Errors: These are the differences between the observed data or taken values and what is really happening in nature, which can lead to a misinterpretation of what is actually going on. These errors might be systematic mistakes performed by the researcher when measuring, taking data, applying the treatment, etc. Or they might be due to random errors, which are due to failures in the instrumentals, changes in the environment, a single mistake of the researcher while taking measures, among others. During the first year, the researcher might plant the two crops under different conditions (parcels with different slopes which affect solar-radiation) or might commit a mistake while applying the fertilizer (different concentrations for example), or might take wrong measures of the height of the corns. During the second year, she can fail in irrigating the crops correctly, providing more water to one of the fields. She can commit the same measuring mistakes. Or even climatic and environmental conditions might change and have different consequences on each of the fields.LIST THREE NATURAL PROCESS THAT AFFECT THE ECOSYSTEM

D)
repeatedly back and forth through living and nonliving parts of the ecosystem
Answer:
D) repeatedly back and forth through living and nonliving parts of the ecosystem
Explanation:
Matter is contained in both living and non-living components of the Earth. An atom is the smallest indivisible component of every matter. This means that matter is made up of atoms.
In an ecosystem, organisms feed on one another in order to survive. However, as they do this, matter is transferred from one organism to another. This transfer of matter (atoms) occurs repeatedly repeatedly back and forth in a cyclical manner through living and nonliving parts of the ecosystem.

Because of a snowstorm, your regular laboratory session was cancelled and the gram staining procedure performed on cultures incubated for a longer period of time. Examination of the stained B. cereus slides revealed a great deal of color variability, ranging from an intense blue to shades of pink. Account for this result.
Answer:
Bacteria start to die, thereby changing the dye concentration in the medium and producing different colors
Explanation:
Bacillus cereus are Gram-positive, rod-shaped bacteria that form orange-pink colonies in agar media (e.g., BACARA medium, which is used for detection and enumeration of B. cereus). In this case, it is expected that after a long time without taking care of the culture, the bacteria started to die. Subsequently, lysed bacterial cells lost their dye which accumulated in some areas of the medium, thereby showing different colors ranging from an intense blue (areas with dead bacteria) to shades of pink (areas with bacteria still alive and viable).
The color of some colonies are changing bacause of long incubation due to death of bacteria.
Bacara agar medium:
It is used for detection and enumeration of B. cereus. Bacteria gives orange-pink colonies in the media.
This detection method only detects the live bacteria, but here bacteria are dieing because of lake of food in media.
Therefore, the color of some colonies are changing bacause of long incubation due to death of bacteria.
