Answer:
hyperosmotic
Explanation:
Osmosis across a membrane occurs in nature as a result of concentration gradient i.e. difference in the solute concentration. Based on the concentration of solute in a solution which determines the osmotic pressure, a solution can either be hyperosmotic, hypoosmotic or isosmotic.
A hyperosmotic solution is that solution which contains more solute concentration in relation to another solution. In essence, a hyperosmotic solution will have more osmotic pressure than that of the body fluid. This will cause water to flow out of the body into the solution.

A dead zone refers to Group of answer choices a) terrestrial areas in which excessive nitrogen fertilizer has essentially burned the soil, preventing plants and microorganisms from living there. b) oligotrophic areas in water bodies that cannot support life due to lack of nutrients. c) an ecosystem that was cleared of all vegetation for slash and burn agriculture. d) hypoxic areas in water bodies that limit marine and aquatic life.
Answer:
The correct answer is d) hypoxic areas in water bodies that limit marine and aquatic life.
Explanation:
A dead zone are oxygen-deprived regions, that is, they are large bodies of water that contain little or no oxygen, both in the depths and near the coasts in the oceans. Aquatic and marine dead zones can be caused by climate change, a product of human activity. When the temperature is high, the water does not have the same density and there is less exchange between the depths of the hydrogen peroxide and the surface water, and these no longer receive oxygen. Marine fauna, not finding the oxygen necessary for their survival, end up suffocating due to the lack of oxygen. They may also have reproductive problems and diseases, making it difficult for them to survive.

oxygen is carried by blood to all the cells of body in the form of ___________
Answer:
Oxygen is carried by blood to all the cells of the body in the form of haemoglobin.
Explanation:
Oxygen is carried in the blood in two forms:
(1) dissolved in plasma and red blood cells water (about 2% of the total)
(2) reversibly bound to haemoglobin (about 98% of the total).
Haemoglobin is a protein in the red blood cells and carries oxygen around our bodies. At the same time, carbon dioxide that is dissolved in the blood comes out of the capillaries back into the air sacs, ready to be breathed out.
Recall that one approach to the study of cell cycle regulation has been to fuse cultured cells that are at different stages of the cell cycle and observe the effect of the fusion on the nuclei of the fused cells (heterokaryons). When cells in Gl are fused with cells in S, the nuclei from the Gl cells begin DNA replication earlier than they would have if they had not been fused. In fusions of cells in G2 and S, however, nuclei continue their previous activities, apparently uninfluenced by the fusion. Fusions between mitotic cells and interphase cells always lead to chromatin condensation in the nonmitotic nuclei. Based on these results, identify each of the following statements about cell cycle regulation as probably true (T), probably false (F), or not possible to conclude from the data (NP). Sort each statement into the appropriate bin.
1. The transition from mitosis to G1 appears to result from the disappearance or inactivation of a cytoplasmic factor present during M-phase.
2. The activation of DNA synthesis may result from the stimulatory of one or more cytoplasmic factors.
3. Gl is not an obligatory phase of all cell cycles
4. The transition from G2 to mitosis may result from the presence in the G2 cytoplasm of one or more factors that induce chromatin formation.
5. The transition from S to G2 may result from the presence of a cytoplasmic factor that inhibits DNA synthesis.
A. T
B. F
C. NP
Answer:
1. T
2. T
3. NP
4. F
5. F
Explanation:
In somatic cells, the cell cycle can be divided into 1-the interphase, 2-the mitotic phase or M phase, and 3-the G₀ phase. In turn, the interphase of the cell cycle can be divided into three phases: 1-the gap 1 (G1) phase or growth 1 phase, 2-the S phase (DNA replication or DNA synthesis), and 3-the gap 2 (G2) phase or growth 2 phase. During the G1 phase, the cell synthesizes key enzymes which are required during DNA replication (S phase) and cell division (M phase). Cytoplasmic factors are proteins and messenger RNAs (mRNAs) that control cell functions during the cell cycle. This cycle is modulated by proteins known as control factors, i.e., cyclins and cyclin-dependent kinases (Cdks) that work together to control the progression through different phases of the cell cycle. The transition from S to G2 occurs after DNA replication. This transition (S to G2) is controlled by a DNA damage checkpoint orchestrated by the ATM (Ataxia telangiectasia mutated) and ATR (Ataxia Telangiectasia and Rad3 related) kinases which are recruited to DNA damage sites. Moreover, the transition from G2 to M phase is mediated by the accumulation of mitotic inducers, which lead to an increase in the activity of mitotic kinase and finally trigger mitotic entry.

(*) Sorry for my late answer but I hope this helps others that are looking for this.
100% in the test ;)
Humus is made of Earthworms, nutrients and bacteria. So, the correct options are A, B and C.
What is Humus?Humus is the soil's black organic material that results from the breakdown of plant and animal debris. It is a type of organic material for soil. It has a lot of nutrients and keeps the soil moist. The Latin word for "earth" or "ground" is humus.
Humus is described as a dark organic substance that develops in soil as a result of plant and animal debris decomposing. It is organic and dark in colour because carbon has accumulated there. It contains elements that are crucial to maintaining healthy soil. Earthworms, nutrients, and microbes make up humus.
Because humus is a feature of loamy soils, the high concentration of nutrients in the soil is caused by humus. Humus reduces a substance's porosity by obstructing the pores that permit the passage of water and air.
Therefore, the correct options are A, B and C.

stay safe healthy and happy...Should we clone animals that are going or have gone extinct (in other words bring them back
either from the brink of extinction or from extinction)? Explain your answer.
Answer:
I think we should but people are preventing this though
Explanation:
I think we should because it might benefit the world and let scientists to discover this animal. But then I don't think so because animals that are/were extinct could perhaps be from climate change. Nowadays, people don't take this matter seriously causing habitats to be destroyed and animals to be extinct :) Like icebergs are melting that mean penguins are at risk of being extinct,if we did something then this situation will be prevented. However dinosaurs did become extinct and they did not come back so its probably just life and this is how god planned it:)
Use the coordinates of the labeled point to find the point-slope equation of

O A. y+ 5 = -3(x - 3)
B. y- 5 = -3(x+3)
C. y + 5 = 3(x+3)
O D. Y-3 - (x+5)
Answer:
A. y + 5 = -3(x - 3)
Explanation:
Given the following data;
Points on the graph (x1, y1) = (3, -5)
Points on the graph (x2, y2) = (0, 4)
First of all, we would determine the slope of the equation of line;
Mathematically, the slope of a line is given by the formula;
[tex] Slope, \ m = \frac {Change \; in \; y-axis}{Change \; in \; x-axis} [/tex]
[tex] Slope, \ m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the formula, we have;
[tex] Slope, \ m = \frac {4 - (-5)}{0 - 3} [/tex]
[tex] Slope, \ m = \frac {4 + 5}{0 - 3} [/tex]
[tex] Slope, \ m = \frac {9}{-3} [/tex]
Slope, m = -3
Next, to find the point-slope equation of the line, we would use the following formula;
y - y1 = m(x - x1)
y - (-5) = -3(x - 3)
y + 5 = -3x + 9
y = -3x + 9 - 5
y = -3x + 4 = mx + c

b. the very early use of pigment, likely for symbolic behavior.
c. animal butchery for the first time.
d. bladelet stone-tool technology, previously dating to 70,000 years ago.
e. the human capacity to exploit coastal environments.
Answer: C. Animal butchery for the first time
Explanation: The discoveries in the cave suggest that humans were harvesting food from the sea (including shellfish and other marine resourses), the use of complex small stone tools and using red pigments in symbolic behavior 164,000 years ago.
A paleoanthropologist (with the Institute of Human Origins at Arizona State University); Curtis Marean, who was the Lead of the research team expressed the aforementioned discoveries while presenting their reports on the research.
He further indicate that these discoveries translates that humans must have been living along this coastal environment at that early time while exploiting it resourses.
Toluene crosses pure lipid bilayers many hundreds of times faster than a related compound, phenylalanine. Suggest two different properties of these molecules that would account for this difference.
Answer:
The lipid bilayer is hydrophobic that is hydrophobic and it can easily cross the lipid bilayer.
Toulene is a hydrophobic and neutral molecule compound so it can easily pass through the bilayer. It is an aromatic compound with a methane group attached to the benzene ring. It is smaller in comparison to Phenylalanine.
Phenylalanine-- It is an amino acid with a benzene ring attached to it. This amino acid is less hydrophobic than the aliphatic amino acids. Because of its less hydrophobic nature, it travels slowly compared to Toluene. It is also larger and has amino and carboxyl groups attached to it. On the other hand, Phenylalanine is a polar compound which has -COOH and -NH2 group. which prevents its delay in its transport across the lipid bilayer.
