A student examines a thin section of an onion-root tip and records the number of cells that are in each stage of the cell cycle. She observes 93 cells in interphase, 15 cells in prophase, 4 cells in metaphase 6 cells in anaphase and 2 cells in telophase. If the complete cell cycle in an onion-root tip cell requires 24 hours, what is the average duration of each stage in cycle?

Answers

Answer 1

Answer:

given:

Total number of cells in all stages = 93+15+4+6+2 = 120

Total time = 24 hours.

solution:

Percentage of cells in interphase

= 93 * 100 / 120 = 77.5%

 in prophase

=15 * 100 / 120 = 12.5%

 in metaphase

= 4 * 100 / 120 = 3.33%

 in Anaphase

= 6 * 100 / 120 = 5%

 in telophase

= 2 * 100 / 120 = 1.66%

The percentage of cells present in various phases exhibits the time spend by each cell in that phase.

Total minutes

= 24*60 = 1440

Total minutes spent in interphase

= 77.5 * 1440

= 1116 minutes

in prophase =12.5 *1440

=  180 minutes

 in metaphase = 3.33*1440

=  48 minutes

in Anaphase = 5*1440

= 72 minutes

 in telophase = 1.66*1440

=  24 minutes

First a glucose molecule enters the body cell, and then a glucose molecule is broken down in the cytoplasm. Then, oxygen is used to break down smaller molecules, smaller molecules enter the mitochondrion. Finally, a large amount of energy is released.

Explanation:

After you ate an energy bar full of glucose, the molecules will first enter the cells, prepare to be broken down in the first site, cytoplasm. And now, oxygen takes a part in it, continue to break it down. The smaller molecules now enter the energy source of a cell, which is mitochondrion, the energy will be released here.

Explanation:

The relationship between predator and prey is the interaction between predator and prey. A predator is is an organism that lives on hunting down other organisms for their nutrition and energy while the prey is an organism that is getting killed or hunted down by a predator. The population of prey is controlled by predators.

Here, the jaguar depends for their nutrition and energy on turtle and other organisms, therefore, jaguar hunt the turtles for their food which makes this a predator-prey relationship.

Answers

Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. 2. Adaptedness is the state of being adapted: the degree to which an organism is able to live and reproduce in a given set of habitats.

On the western peninsula, the changing climate means different weather is turning sheets of snow and ice into a land of rain and mud. Older penguins are equipped with waterproof layers of feathers allowing them to move swiftly in the water, and also allowing them to stay warm on land.

Carrying capacity can be defined as a species' average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.

6.Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.

There are millions of organisms on Earth that scientists have classified into different levels of organization. Which of these characteristics would be most important to scientists when classifying organisms?
a)where the organism lives
b)how small the organism is
c)the genes of the organism
d)the shape of the organism

Answers

Answer:

I think no. b is the ans or maybe not

There are millions of organisms on Earth that scientists have classified into different levels of organization. The characteristics which would be most important to scientists when classifying the organisms will be the genes of the organism. Thus, the correct option is B.

What are the different levels of organization?

Taxonomy is the study of classification of organisms. Scientists have used many different types of information to place the different organisms into specific groups. The groups are arranged in different levels. These levels were named as kingdom, phylum, class, order, family, genus, and species.

The organisms which were present on the Earth were classified on the basis of the environment where they live, how small is the size of the organism, and the shape of the organism found such as rod-shape, cocci, spirillum, etc.

Therefore, the correct option is B.
