The process of osmosis is best illustrated by the movement of a. water into root hair cells b. oxygen intro red blood cells c. carbon dioxide through stomates d. glucose through phloem
Answer:
a. water into root hair cells
Explanation:
Osmosis can be defined as a process which typically involves the movement of a solvent molecule such as water through a semi-permeable from a region of high concentration to a region of lower concentration.
Hence, the process of osmosis is best illustrated by the movement of water into root hair cells because they are used by the plants to absorb water from the soil.

Resources such as food, water, light, space, shelter and access to mates are all limiting factors. If an organism, group or population does not have enough resources to sustain it, individuals will die through starvation, desiccation and stress, or they will fail to produce offspring.
Is the Monocercomonoide considered a life form?
Answer:
Monocercomonoides isn’t a living fossil, a holdout from the days of the earliest eukaryotes, Karnkowska notes. Its closest relatives still have small mitochondria, suggesting that it jettisoned the organelles fairly recently in evolutionary terms. She and her colleagues speculate that more eukaryotes missing mitochondria await discovery.
Explanation:
Answer:
Monocercomonoides isn’t a liviing form

define homologous structure in YOUR OWN WORDS
Answer:Homologous structures are similar structures that evolved from a common ancestor. Learning Objectives. Describe the connection between evolution and the appearance of homologous structures.
Explanation:A common example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure.Following are some examples of homology: The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar and share common traits.Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. Figure below shows the hands of several different mammals. They all have the same basic pattern of bones.Homologous structures share a similar embryonic origin. Analogous organs have a similar function. For example, the bones in a whale's front flipper are homologous to the bones in the human arm.

Which of these would provide the best evidence for the theory of evolution?
A
fossils of ancient tigers that had larger ears than tigers have today
B
oil found deep under the ice sheets of Antarctica
C
a person’s hair growing faster in the summer than it does in winter
D
ancient maps that show that countries had different borders long ago
Answer:A
Explanation:
The meaning of evolution-the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
So, B is incorrect since it is talking of the present. C, shows the growing of hair, but has no answer to evolution, since it does not show an organism growing from the past to present. D, shows evolution of land but no “living organism”
In conclusion, the best answer is A.

The temperature in her room will stay the same. :))

Three plants were grown to study the effects of nitrate and magnesium ion deficiency on their development. They were kept in the same conditions, except for the types of minerals supplied.
Use
Plant A was provided with all essential minerals.
Plant B was given all minerals except nitrate ions. Plant C was given all minerals except magnesium ions. State three conditions, other than water and the concentration of mineral ions, that would need to be kept the same for all the plants, in order to make the investigation a fair test
Answer:
Periods of light-timeTemperatureSubstrate/Soil typeExplanation:
Controlled variable: Variables that are controlled and have no influence on the results of the experiment. These variables do not affect the change in the dependent variable values.
These variables must be the same for all the subjects or groups (control and experimental). In the case of plants, controlled variables are probably those needed by the plants to correct development.
All plants should be exposed to the same period of light-time and the same temperature. Also, the substrate or soil where the plants are growing should be the same.
A student uses a microscope to observe cells in the root tissue of an onion. He
concludes that the cells are reproducing by mitosis.
Which hypothesis is supported by his conclusion?
a. The root tissue cells all have the same set of chromosomes.
b. The root tissue cells each have a unique genetic make-up.
c. The root tissue cells produce identical gametes..
d. The root tissue cells split to form stem cells.
The correct answer is option a. The root tissue cells all have the same set of chromosomes as it clearly explains the hypothesis.
Onions (Allium cepa L.) have eight relatively large chromosomal pairs (2n = 16) that can easily detect CA.
Mitosis creates two identical daughter cells, each containing the same number of chromosomes as the parent cell. In contrast, meiosis produces four unique daughter cells, each with half the number of chromosomes in the parent cell. Therefore, during the mitotic cell cycle, the DNA content per chromosome doubles in the S phase (each chromosome begins as a chromatid and becomes a pair of identical sisters in the S phase). However, the number of chromosomes remains the same.
How many chromosomes do cells have after the G1, S, and M phases?Onion root cells have chromosome 16 in each cell after the G1, S, and M phases.
Thus it concluded that mitosis causes root tissue cells to all to have the same set of chromosomes.
