Candice is examining a cell under a microscope. She has identified a cell wall, a nucleus, and chloroplast. What type of organism does this cell most likely belong to.
1.plant
2.fungus
3.animal
4.bacterium
Answer:
1. Plant
Explanation:
Only a plant has a cell wall, chloroplast, and nucleus. Since eukaryotes are the only ones with a nucleus, that cancels out bacteria and fungi. Since there is a chloroplast, you can tell that the cell has to be one of an autotroph which gives you plant.
A botanist has recently developed an enzyme called NoGro. This enzyme acts as an
herbicide by preventing cell growth in the leaves of a certain species of tree that is an
invasive plant species in Florida. The botanist wants to test the effects of temperature
on NoGro so that NoGro can be applied to the invasive tree under optimal
conditions on Florida farms. After looking into the background of the study, you
discover that the botanist performing this investigation is being paid by a company
that will make a lot of money if NoGro proves to be useful at eradicating the invasive
tree. How might this affect your view of the research in this experiment?
Answer:
results could be biased and therefore they are not reliable
Explanation:
A conflict of interest is generated when the authors of a given study have any type of interest that could influence their judgments, results and/or conclusions. These conflicts of interest include any relevant financial relationships, personal, religious, political or intellectual interests. To solve this situation, peer-reviewed, well-reputed journals generally include a conflict of interest statement where authors declare all interests that might be perceived as conflicting.

Root systems are classified as fibrous root systems and taproot systems.
Which property distinguishes the two types of root systems from each other?
A)
the method of water absorption
B)
the branching pattern of the roots
C)
the presence of xylem and phloem
D)
the growth rate of the roots
Answer:
B) the branching pattern of the roots
Explanation:
Plant roots function as anchors, food storage and aid in the uptake of water and minerals- other modifications include gas exchange and chemical signaling.
Root systems are mainly classified as taproots, usually found in dicots or fibrous roots found in monocots - some plants are a varying combination of the two systems. While tap roots consist of a larger, vertical main root surrounded by smaller lateral roots, fibrous roots are typically a dense network of roots that grow near the surface of the soil.
Taproots are thought to be more common in plants inhabiting regions experiencing water scarcity, while fibrous roots are thought to grow in more lush, water-abundant regions.
Examples of these roots systems include...
taproots: dandelions, carrots, turnipsfibrous roots: grasses, cornIf you saw a bacteria cell without a tail, where could they live where they don’t need a tail?

"An advantage of ______ reproduction is that a genetic disorder in a parent might not affect The offspring
Answer:
An advantage of sexual reproduction is that a genetic disorder in a parent might not affect the offspring.
Explanation:
got 100
Answer:
An advantage of sexual reproduction is that a genetic disorder in a parent might not affect the offspring.
Explanation:
Since there are only two types of reproduction, sexual and asexual, andin asexual reproduction, the offspring gets all the qualities of the parent, we can determine that the offspring might not get the genetic disorder from the parent IF it is sexual. That is because there are 2 parents, hence giving a 50-50 chance to get it.
Scientific evidence shows that modern dogs, wolves, and foxes all have a common ancestor. Further evidence shows that dogs are more closely related to wolves than to fixes. Which of the following observations provides the BEST evidence that dogs are more closely related to wolves than to foxes? *
A. The diets of dogs and wolves are more similar that the diets of dogs and foxes.
B. The lifespans of dogs and wolves are more similar than the lifespans of dogs and foxes.
C. The genetic sequences (DNA) of dogs and wolves are more similar than the genetic sequences of dogs and foxes.
D. The body sizes of dogs and wolves are more similar than the body sizes of dogs and foxes.
The observation that provides the best evidence that dogs are more related to wolves than to foxes is the DNA sequence of dogs and wolves being more similar than that of dogs and foxes.
The DNA is a molecule that stores the genetic information of organisms. Thus, closely related organisms have similar information on their DNA, usually indicated by similar nucleotide sequences.
Therefore, if dogs and wolves are more closely related in ancestry than dogs and foxes, the DNA sequence of dogs and wolves will be more similar than the DNA sequence of dogs and foxes.

Grassland songbirds often nest in the same grassland-wetland complexes as waterfowl, particularly in a certain part of those complexes, namely, upland habitats surrounding wetlands. Although some wildlife management procedures directed at waterfowl, such as habitat enhancement or restoration, may also benefit songbirds, the impact of others, especially the control of waterfowl predators, remains difficult to predict. For example, most predators of waterfowl nests prey opportunistically on songbird nests, and removing these predators could directly increase songbird nesting success. Alternatively, small mammals such as mice and ground squirrels are important in the diet of many waterfowl-nest predators and can themselves be important predators of songbird nest. Thus, removing waterfowl-nest predators could affect songbird nesting success through subsequent increases in small-mammal populations.
In 1995 and 1996, researchers trapped and removed certain waterfowl-nest predators, primarily raccoons and striped skunks, then observed subsequent survival rates for songbird nests. Surprisingly, they observed no significant effect on songbird nesting success. This may be due to several factors. Neither raccoons nor striped skunks consume ground squirrels, which are important predators of songbird nests. Thus, their removal may not have led to significant increases in populations of smaller predators. Additionally, both raccoons and striped skunks prefer wetlands and spend little time in upland habitats; removing these species may not have increased the nesting success of songbirds in the uplands enough to allow detection.
According to the passage, which of the following is true about the role played by ground squirrels in the ecology of grassland-wetland complexes?
(A) While not important in the diet of raccoons or striped skunks, ground squirrels are a significant source of food for other waterfowl-nest predators.
(B) Whereas ground squirrels are typically important as predators of songbird nests, their opportunistic predation on waterfowl nests also has an observable effect on waterfowl nesting success.
(C) Although most waterfowl-nest predators prey on small mammals such as mice and ground squirrels, populations of ground squirrels tend to increase quickly enough to compensate for this level of predation.
(D) Although ground squirrels have been known to prey on songbird nests, a larger portion of their diets is usually provided by predation on waterfowl nests.
(E) Since larger predators tend to prefer small mammals to songbird eggs as a food source, a large population of ground squirrels plays an important role in controlling opportunistic predation on songbird nests.
Answer:
(A) While not important in the diet of raccoons or striped skunks, ground squirrels are a significant source of food for other waterfowl-nest predators.
Explanation:
According to the passage, some predators of waterfowl nests prey opportunistically on songbird nests. Therefore, some wildlife management procedures directed at waterfowl, such as habitat enhancement or restoration, may also benefit songbirds. However, some procedures such as predator control may not always lead to benefits for the songbirds. For example, some predators of waterfowl nests such as raccoon and striped skunks are not predators of small mammals such as mice and ground squirrels who themselves are predators of songbird nests. So removing the striped skunk and raccoons from the habitat of the waterfowl and songbird nests, may not bring any benefit whatsoever to the songbirds. However, many other predators of waterfowl nests are also predators of squirrels and mice.

Describe the circumstances of a solar eclipse.
A solar eclipse happens when the Moon passes in front of the Sun and casts a shadow across Earth.
For a total eclipse to take place, the sun, moon and Earth must be in a direct line. The second type of solar eclipse is a partial solar eclipse. This happens when the sun, moon and Earth are not exactly lined up. The sun appears to have a dark shadow on only a small part of its surface.
Once blood tonicity is negatively impacted, can the consequences be reversed?
Answer:
No.
Explanation:
Once blood tonicity is negatively impacted, the consequences can't be reversed because this tonicity permanently damaged the cell. For example, in hypotonic solution, If the water continues to move into the cell due to high solute concentration, it can damaged the cell membrane, the cell bursts and dies. But it can be reversed if the cell loses its water and become shrink in hypertonic solution and regain its original size by normalizing the water level.

C) warm and moist
D) cold and dry
I need this today please help
Answer:
I'm pretty sure its c
Explanation:
Warm and moist kind of air mass forms over tropical waters that have been heated by the sun. Hence option C is correct.
What are topical waters?Topical waters are defined as water between the Tropic of Cancer (23.5° North latitude) and the Tropic of Capricorn (23.5° South latitude). In the Köppen climatic classification, a tropical climate is one in which the average monthly temperature is over 18°C. There is no winter season and there is more annual rainfall than annual evaporation.
A good illustration of this kind of fish is the goldfish. On the other hand, "tropical" or "warm water" fish require a water temperature that is optimal for their comfort and health. Although different species of fish have varying needs, tropical fish generally demand water that is between 76 and 80 degrees Fahrenheit (25 and 27 degrees Celsius).
Thus, warm and moist kind of air mass forms over tropical waters that have been heated by the sun. Hence option C is correct.

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.
