Answer:
1. The cells in our bodies are surrounded by these types of solutions. → Isotonic solution.
3. When an animal cell is places in this solution, it will burst (get layer) → Hypotonic solution.
4. When an animal cell is placed in this solution, it will shrivel or shrink (get smaller) → Hypertonic solution.
Explanation:
The cells in the body are in a balance of substances —concentration of solutes— between their cytoplasm and the extracellular space. This balance is dynamic in living beings, due to the constant exchange of ions and substances between the intracellular and extracellular space. For this reason, the extracellular medium is isotonic with the cytoplasm.
A cell can lose or gain water depending on the amount of solutes that a medium has in which it is found, with respect to the cytoplasm. This difference in solutes concentrations produces an osmotic gradient that drags water from the least concentrated solution to the most concentrated, through the process of osmosis, which seeks to achieve an equilibrium of concentrations.
When a animal cell is exposed to a hypertonic solution —with a higher concentration of solutes— it loses water and tends to dehydrate and become smaller.An animal cell in a hypotonic solution receives water, so it can expand and even burst.In practice, the concentrations of intracellular and extracellular solutes depend not only on the osmotic gradient, but also on the concentration gradient of substances.

Hemophilia is a recessive sex-linked disorder (Xh). A man with hemophilia and a female carrier are concerned about their daughter inheriting the disorder. Use a punnett square explain to these parents the probability (percent chance) that their daughter could have the disorder.
Answer:
The chances of a hemophilic man and a female carrier having a that one of their daughters inherits the disease are 25%.
Explanation:
Since hemophilia is a disease with a sex-linked recessive inheritance pattern —X chromosome— all males who acquire the altered gene will have hemophilia ([tex]X^{h}[/tex]Y), while a female should have both altered chromosomes ([tex]X^{h}[/tex]X) to manifest the disease.
If a hemophilic male and a female carrier of the hemophilia gene have children, the possibility of having a daughter with hemophilia can be seen by crossing.
♂ [tex]X^{h}[/tex]Y♀ [tex]X^{h}[/tex]XAlleles [tex]X^{h}[/tex] Y
[tex]X^{h}[/tex] [tex]X^{h}[/tex][tex]X^{h}[/tex] [tex]X^{h}[/tex]Y
X [tex]X^{h}[/tex]X XY
In the offspring, there are:
Healthy sons 25%.Hemophilic sons 25%.Carrier daughters 25%.Hemophilic daughters 25%.The hemophilic man and the carrier woman should know that they have a 25% chance of having a hemophilic daughter, or that 50% of their daughters may have the disease.

Genes, the environment, and the organism
The net outcome of the reading of a gene is that a protein is made that generally has one of two basic functions, depending on the gene. First, the protein may be a structural protein, contributing to the physical properties of cells or organisms. Examples are microtubule, muscle, and hair proteins. Second, the protein may be an enzyme that catalyzes one of the chemical reactions of the cell. Therefore, by coding for proteins, genes determine two important facets of biological structure and function. However, genes cannot dictate the structure of an organism by themselves. The other crucial component in the formula is the environment. The environment influences gene action in many ways, about which we shall learn in subsequent chapters. In the present context, however, it is relevant to note that the environment provides the raw materials for the synthetic processes controlled by genes. For example, animals obtain several of the amino acids for their proteins as part of their diet. Most of the chemical syntheses in plant cells use carbon atoms taken from the air as carbon dioxide. Bacteria and fungi absorb from their surroundings many substances that are simply treated as carbon and nitrogen skeletons, and their enzymes convert these components into the compounds that constitute the living cell. Thus, through genes, an organism builds the orderly process that we call life out of disorderly environmental materials

If a substance is more highly concentrated outside the cell than inside the cell and the substance can move through the cell membrane, the substance will move by diffusion
What are diffusion and its importance?
Diffusion is the transfer of individual molecules of material from a region of higher concentration to a region of lower concentration over a semipermeable barrier
Cells depend on diffusion to get the nutrients they need to develop and obtain energy as well as to rid themselves of waste materials. It helps in gaseous exchange during respiration in organisms.
Thus, when a substance is more highly concentrated outside the cell than inside the cell and the substance can move through the cell membrane, then the substance will move by diffusion

What factor affects the temperature of ocean water?
Answer:
The following factors affect the distribution of temperature of ocean water: (1) Latitudes: The temperature of surface water decreases from equator towards the poles because the sun’s rays become more and more slanting and thus the amount of insolation decreases poleward accordingly.
Explanation:
Answer:
Depth
Explanation:
The ocean has three layers from the top to bottom containing different temperatures. The first layer is of warm oceanic water approximately 500 m think containing temperatures of about 20 degrees Celsius to 25 degrees Celsius. The second layer is the thermocline layer characterized by a decreasing temperature with increased depth. The last layer is that of very cold temperature that extends to the deep ocean floor. There are other factors which affect the distribution of temperature of ocean water which include: latitudes, unequal distribution of land and water, prevailing wind and ocean currents.

B. net 2 NAD+, 2 ATP, 4 CO2, 2 FADH
C. net 4 NADH, 4 ATP, 8 CO2, 4 FADH2
D. net 1 NADH, 1 ATP, 2 CO2, 1 FADH2
Answer:
Its A
Net 2 NADH, 2 ATP, 4 CO2, 2 FADH2
The Krebs cycle forms 2 NADH, 2 ATP, 4 CO2 and 2 FADH2 after one molecule of glucose goes through it. So the correct option is A.
What is the Krebs cycle?The Krebs cycle is also known as the TCA cycle (tricarboxylic acid) or the citric acid cycle. It is the main source of cellular energy and an important part of the entire process of aerobic respiration.
In this cycle, the available energy of Acetyl coenzyme A is utilized and converted to Nicotinamide Adenine Dinucleotide (NADH). In glycolysis, glucose is utilized to form pyruvate. The pyruvate is oxidized to Acetyl coenzyme A and then it enters the TCA cycle.
The intermediates involved in the pathway also form intermediates for many other pathways to form porphyrins, amino acids, fatty acids etc. Thus, any disturbance in this cycle will not only disturb itself but many other pathways.
Therefore, the end products of the Krebs cycle are 2 NADH, 2 ATP, 4 CO2 and 2 FADH2. Hence the correct option is A.

How much energy is passed from plants to primary consumers?
Answer:
Explanation: Primary consumers only obtain a fraction of the total solar energy about 10% captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. You can probably see where this is going. Primary consumers are eaten by secondary consumers.

Answer:
B. The cell wall and vacuole function to maintain the structure of plant cells
С. Chloroplasts allow the cell to store energy, and mitochondria release energy for the cell
E. Molecules can enter the cell by passing through the cell membrane and may take part in chemical reactions within the cytoplasm
Explanation:
Homeostasis, which is key to the survival of an organism, is the ability of a living organism's cell to maintain a stable internal environment despite changes to the external environment. Cell structures/organelles interact with one another in order to maintain homeostasis as follows:
- The cell wall and vacuole function to maintain the structure of plant cells. The cell wall is responsible for the rigidity of the plant cell while the water content of the vacuoles make the cell turgid.
- Chloroplasts allow the cell to store energy in the bonds of the glucose molecules that form as a result of the photosynthesis that occurs in the CHLOROPLAST while the mitochondria release energy for the cell due to the cellular respiration process that breaks down the glucose molecules to release ATP.
- Molecules needed by the cell can enter the cell by passing through the cell membrane and may take part in chemical reactions within the cytoplasm.
The cell structure that has been able to maintain homeostasis has been the cell wall, chloroplast, and cell membrane. Thus options B, C, and D are correct.
The cell has been the smallest unit of the body. Cell performs various functions with the help of organelles. Homeostasis has been defined as the self-regulating system of the body.
Varying organelles in the body have been responsible for the homeostasis process. The cell wall and cells structure of the cell have been maintained within the plant cells.
The process of photosynthesis has been performed with the plant cells with the help of chloroplasts.
The cell membrane has been the semipermeable membrane that helps in the transport of the molecules across the cell.

Why would an ecosystem With only a few different types of organizations to be more susceptible to disruption in an ecosystem with many different types of organisms
Answer:
Explanation:
Base on my understanding of your question, it seems you are comparing susceptibility of disruption of ecosystems with fewer organizations to that of numerous organizations.
Let start from the definition of an ecosystem which can be defined as community of living organisms such plants, animals and non living organisms components in the same environment cohabiting to form a system and are linked together through nutrients and energy cycles. In other word, we can say no organisms exist in isolation and as such they are depend on each others. We also have different type of organisms in an ecosystem which are character as consumer; those that predate on others for their surviver which are known as heterotroph, while some are capable of producing their own food and are termed autotroph either through photosynthesis or chemosynthesis. Some organismsalso feeds on dead things and they are termed Scavengers or detritivores.
So, going by these explanations, ecosystem with few organizations will be more susceptible to disruption because some organisms will go into extinction as they are being eaten up by heterotroph organism and as such themselves will not survived as their will no food for them to feed on again. As such, the cycle will not complete leading to break in nutrients and energy cycles and eventually the ecosystem will be disrupted. While those with many organizations, the cycles continued as the food chain continues and the ecosystem continue to exist.
