Answer:

Form the cell membrane around food to create a vacuole that is kept separate from the rest of the cytoplasm while enzymes break down the food.

Cells maintain homeostasis without using energy by relying on passive transport processes.

Passive transport mechanisms do not require the input of cellular energy (ATP) and instead rely on the inherent kinetic energy of molecules and the concentration gradients of substances.

One common example of passive transport is simple diffusion, where molecules move from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Similarly, facilitated diffusion utilizes protein channels or carriers to facilitate the movement of specific molecules across the cell membrane without energy expenditure.

Osmosis is another passive process where water molecules move across a selectively permeable membrane to balance the concentration of solutes on both sides.

By utilizing these passive mechanisms, cells can maintain a stable internal environment and achieve homeostasis without the need for energy expenditure.

Explanation:

If the purple flower is heterozygous:

                Pp    x    pp

            Pp   Pp   pp   pp

the expected ratio of purple flower offspring to yellow flower offspring would be 50:50.

Chi square = [tex]\frac{(O - E)^2}{E}[/tex] where O = observed frequency and E = expected frequency.

phenotype            O              E                 Chi square

purple                   87             73                [tex]\frac{(80-73)^2}{73}[/tex] = 0.67

yellow                   59             73                [tex]\frac{(59-73)^2}{73}[/tex] = 2.68

Total = 0.67 + 2.68 = 3.35 to the nearest tenth = 3.4

Degree of freedom = 2 - 1 = 1

Critical Chi square value (alpha = 0.05) = 3.84  

SInce the critical Chi square value is greater than the calculated value, the null hypothesis is accepted.

Answer:

Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation. Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Answer:

People feel fireworks before hearing it because light travels faster than sound.

Explanation:

We always see the colors of the fireworks before hearing their defeaning sounds. This is because light travels faster than sound, so we can see the light before hearing the sound. An example of this is seeing lightning before hearing thunder. When lightning strikes, the air around it moves very quickly, causing vibrations.

Answer:

1: The process of osmosis would cause water to move into the cells causing them to swell and possibly burst. Many freshwater one celled organisms have structures called contractile vacuoles. These structures collect and pump out excess water that accumulates in the cell.

2: During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.

Answer:

The ABO blood type is inherited in an autosomal codominant fashion.

The Rh system of blood groups determines the gene that forms two alleles: dominant (D) and recessive (d).

Explanation:

The dominant allele determines the synthesis of antigen D, so people with this antigen are referred to as Rh +. The recessive allele is dysfunctional so no D antigen is produced and individuals are Rh-

The ABO blood group system determines a gene that has three alleles:

A,  B, and O allele.

Alleles A and B are functional and determine the synthesis of certain antigens (agglutinogens A B) that are found on erythrocytes.

In this exercise we have to use the knowledge of blood to explain its inheritance factors, so we want to explain how:

So we know that blood types in addition to the types known as ABO, there is also the RH factor which is the biggest inheritance.

Type A blood has A antigens, B blood has B antigens, AB blood has both antigens, and type O has neither. Red blood cells also have another type of antigen called RhD, which is part of a family made up of 61 Rh type antigens. When the blood has RhD, it is type positive.

Our blood group is inherited from both parents. Just as we are given physical characteristics like skin color or hair, we also inherit blood type. Surprising as it may seem, blood group is not genetically determined at birth according to the contributions of both parents.

Answer: Enzymes are life’s great facilitators. They create the conditions needed for biochemical reactions to happen fast. The general name that chemists use for chemical entity that increases the speed of a reaction is  “catalyst.” Enzymes are biological catalysts they catalyze the chemical reactions that is happen inside living things.

Explanation:

Answer:

1.0 mole per dm3 sodium chloride solution

Explanation:

The more the molarity of a solution, the lower the water potential of the solution, and the higher the amount of water that will osmotically move from the potato stick to the solution when placed in it in order for an equilibrium to be established.

Hence, the 1.0 mole per dm3 sodium chloride solution will cause the largest decrease in the mass of the potato stick when compared to the 0.5 and 0.1 mole per dm3 sodium chloride solutions.

Answer:

The correct answer is ''The scientific study of heredity''

Explanation:

Genetics is a branch of biology that studies how hereditary characters are transmitted from generation to generation and the diversity that exists among living beings. Inheritance is the physical and biological characteristics that we share with our family and that can determine our appearance and our biological characteristics, that is, our phenotype (eye color, skin type, etc.) as well as our internal characteristics. All of this is largely derived from our genetic components, that is, our genotype.

Answer:

1)Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.

2) The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion

3)onic bonds are important because they allow the synthesis of specific organic compounds. Scientists can manipulate ionic properties and these interactions in order to form desired products. Covalent bonds are especially important since most carbon molecules interact primarily through covalent bonding.

Answer:

The correct answer is option C "determine how a star is moving (toward, away, fast, slow)"

Explanation:

All realized components emanate and assimilate specific frequencies of light, which is important for the electromagnetic range. By considering the frequencies of light (as demonstrated by 'lines' inside the electromagnetic range) discharged by an object in space, astronomers can get a scope of information.

One thing they look at is the adjustment in situation of lines in the range from a star this can tell astronomers the distance away the star is, regardless of whether it is moving towards or away from us and how quick it is moving.
