19.Compared with unpolluted water, the water in a lake polluted by sewage will have
A. fewer microorganisms
C. more fish
B. more oxygen
D. more nitrogen compounds
Answer:
more nitrogen compounds
Explanation:
when water is polluted by sewage many microorganisms is present so we can deduct the 1st ans.
as water is polluted the environment is not suitable so living organisms so unpolluted water has more fish than polluted.
there cant be more oxygen in a place where it s polluted coz plants which grow under water wont grow as it is polluted
more nitrogen compounds is the answer because nitrogen compounds are made due to the reactions in polluted water.

A sample of Carbon-14 originally contained 100 g. After three half-lives have
passed, how much Carbon-14 is left?
Answer:
After 3 half lives 12.5 g of C-14 left
Explanation:
Given data:
Mass of C-14 = 100 g
After 3 half lives mass left = ?
Solution:
At time zero = 100 g
At first half life = 100 g/2 = 50 g
At second half life = 50 g/ 2 = 25 g
At third half life = 25 g/2 = 12.5 g
Thus, after 3 half lives 12.5 g of C-14 left.
7. CASE STUDY For Biosphere 2 to meet its goal, why was it necessary for it to replicate a
variety of climates?
Answer:
For Biosphere 2 to meet its goal, it was necessary to replicate a variety of climates. The original goal was to provide a successful model for human space colonies, and with this goal in mind, scientists and engineers built prototypes of several environments that can replicate the real-life climates (in order to see how the complex processes work). This provides a viable ecological system in outer space. In the model, there are different climates used to see how different factors of the Earth affect each other.

The barrier islands of Georgia are low, sandy islands that form off the coastline and protect the mainland; however, they can be a risky place to reside or develop.
If a builder wanted to construct a mall on one of these islands, which of the following questions would be the most significant concern for him to consider?
A.
Where would be the best place to build the mall so that it is protected from the impact of storms which causes the winds and waves to constantly redistribute the sand?
B.
Since the islands are constantly changing, what location would offer the best access to sand resources to aid in the construction of the mall?
C.
Before construction begins, should large amounts of sand be removed from the island first in order to prevent erosion of the beach?
D.
If an earthquake were to occur, would the islands sink below sea level, causing a huge tidal wave to crash on the mainland?

6.L.14.4 Which is true of only animal cells?
A. Their cytoplasm contains organelles.
B. They do not have a rigid outermost layer.
C. The process of obtaining energy requires sugar.
D. They have organelles that are surrounded by membranes.
Only animal cells have the process of obtaining energy through sugar. Plants on the other hand undergo photosynthesis, which uses sunlight instead of sugar.
Hope this helps! Please correct me if I'm wrong :)
Answer:
B. They do not have a rigid outermost layer.
Explanation:
Several organisms, including bacteria and eukaryotes are heterotrophs- this means that they obtain energy through breaking down organic molecules like sugar, and amino acids made by producers.
Animal cells are eukaryotic; all eukayoted may be single-celled, or multicellular, and contain a nucleus containing genetic material along with membrane-bound organelles in their cytoplasms. Animal cells do not contain rigid cell walls, unlike other eukaryotic cell types like plant cells.
Cell division is completed when which step is finished? (SE 5A) Select one: a. interphase b. telophase c. mitosis d. cytokinesis
Answer: Cytokinesis
Explanation: I am taking this same test right now and got it correct.
Cell division is completed when cytokinesis, which is the final step of mitosis, referring to cytoplasmic division, is completed. So the correct option is D.
What is mitosis?A kind of cell division known as mitosis occurs when a single cell (the mother) splits into two genetically identical daughter cells. Mitosis, when referring to the cell cycle, is the stage of cell division during which the DNA in the cell's nucleus is divided into two identical sets of chromosomes.
Mitosis is used in the vast majority of cell divisions that take place in your body. Mitosis fills an organism's body with cells during development and growth, and it substitutes old, tattered new cells over the course of an organism's existence. Mitotic divisions are a kind of reproduction for single-celled eukaryotes like yeast, resulting in the generation of new members of the population.
In each of these scenarios, ensuring that each daughter cell receives a flawless, complete set of chromosomes is the "objective" of mitosis. In general, cells with too few or too many chromosomes don't function effectively; they may die off or potentially spread cancer. Thus, during mitosis, cells don't just randomly split their DNA into two heaps for the two daughter cells. Instead, they divided up their duplicate chromosomes in a methodical order.
Therefore the correct option is D.

Distinguish between:
Bat and Dove
Answer and Explanation:
Bats are mammals of the order Chiroptera. With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more manoeuvrable than birds, flying with their very long spread-out digits covered with a thin membrane or patagium.
Their wings skeleton have the shape of finger/hands like a human.
Doves are the only family in the order Columbiformes. These are stout-bodied birds with short necks, and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants.
#teamtrees #WAP (Water And Plant)
Answer:
Doves have beaks and no teeth, whereas bats have jaw bones with sharp teeth. Although they both fly, Dove and bats feature different structures that allow them to take flight. Doves have rigid, feathered wings that they flap completely in order to fly.

What system do we use to bind periods, eras, etc., of time together?
Answer:
The Geological Time Scale
Explanation:
The Geological Time Scale is the framework in which the history of the Earth is inscribed. It combines a numerical scale that uses the million years as a unit (chronometric scale) and a scale that is expressed in relative time units (chronostratigraphic scale).
The chronometric scale is based on the measurement of certain physical properties of rocks, generally the relationship between the content of stable and unstable isotopes of the same element.

A.Trout do not have segmented bodies
B. Amoeba are multicellular
C. Trout and Koalas are in the same class
D. Koalas evolved after trout
Answer:
Koalas evolved after trout.
Explanation:
A cladogram is the diagrammatical representation of the relationship between the organisms. From the cladogram, it can be said that Koalas evolved after trout. Thus, option D is correct.
What is a cladogram?A cladogram is used to show the relation between the different species through branching. It tells about the sequence in which the characteristics were derived.
From the cladogram, it can be seen that trouts developed the jaws, and amoeba are unicellular organisms. However, Trouts and Koalas do not share the same class but Koalas evolved after trout in the geological timeline of evolution.
Therefore, the Koalas evolved after trout.
