Answer:
Organs are composed of tissues that are composed of subunits called cells.
Explanation:
In biology, there are five levels of organization that makes up living organisms. These five levels of organization make up one another in the following ascending hierarchical order:
Cell → Tissue → Organ → System → Organism
Based on this hierarchy, cells make up tissues, tissues make up organs, organs make up systems, and systems make up an organism. According to this question, the most accurate description of the levels of biological organization in the option is "Organs are composed of tissues that are composed of subunits called cells".

What is the importance of mitosis for unicellular organisms?
A) asexual reproduction
B) sexual reproduction
C) repair of damaged tissue
D) growth
Answer:
A) asexual reproduction
Explanation:
Mitosis plays an important part in the life cycle of most living things, though to varying extents. In unicellular organisms such as bacteria, mitosis is a type of asexual reproduction, making identical copies of a single cell. In multicellular organisms, mitosis produces more cells for growth and repair.

Starting with the European settlers, humans have introduced earthworms from Europe and Asia into North American forests. These introductions continue through the transport of soil that contains non-native earthworms, such as during construction and through the release of non-native earthworms used for fishing. The effects of non-native earthworms are especially large in forests that did not have any native earthworms. For example, forests of the Great Lakes region did not previously have earthworms until humans introduced them. When non-native earthworms are introduced, the thick layer of leaf litter disappears quickly, thereby altering biogeochemical cycles. You conduct an experiment to compare the nitrogen cycle in soils with and without non-native earthworms. Predict the results of your experiment.
Answer:
The soils with earthworms will show a faster rate of ammonification
Explanation:
Originally, the nitrogen released by organisms when they die (or excrete waste products) is organic nitrogen, e.i., amino acids and nitrogenous bases in DNA. Ammonification is the property that decomposer organisms have to mineralize organic nitrogen in order to produce inorganic nitrogen in the form of ammonium (NH4+). In agroecosystems, earthworm activity can increase the ammonification rate. For example, Lumbricus terrestris is an invasive earthworm (which is native to Europe) that has been shown to increase both ammonification and nitrification (nitrate production) rates in the soil of different ecosystems.

• 11. How does each stage of Meiosis compare to Mitosis?
• 12. Describe three ways that meiosis contributes to genetic diversity in a species?
Answer:
Explanation:
A gamete is a haploid reproductive cell that fuses with another gamete of opposite strain to form a diploid
zygote.
A zygote is a cell formed by the fusion of the male and female gamete before it undergoes division.
gametes are haploid while a zygote is diploid.
There is exchange of genetic material during sexual reproduction and fusion of gametes. Meiosis is also involved.
The opposite occurs in asexual reproduction and mitosis is involved instead.
Asexual reproduction is common in prokaryotes eg bacteria.

A particular species of bacteria has a "a generation time" of 20 minutes. That is, every 20 minutes a single bacterium completes prokaryotic fission -- one bacterium is now two bacterial cells. This morning at 6:00 a.m. you made a sandwich and packed your lunchbox. What you were not aware of was that there were 10 bacteria cells of this species on the dollop of mayonnaise that you spread across your bread. At 12:00 p.m. (no on) You sit down and eat your entire sandwich! How many bacteria cells did you have for lunch? (Hint: use the formula 2axb x C = numbers of cells, where "a" - number of times per hour the bacteria reproduces, "5" the number of hours the bacteria had to reproduce, and "C" = the number of bacteria at the start).
Answer:
Number of bacteria cells = 2621440 cells
Explanation:
The generation time of a bacteria specie is the time it takes for a population of bacteria to double in number. The generation time for most common bacteria is quite short, about 20 minutes to 1 hour.
Bacteria reproduce asexually by binary fission, in which the parent cell divides into two to produce two identical daughter cells.
In the given question, the generation time of the bacterial species is 20 minutes.
The time that have passed from between the time the sandwich was packed at 6:00 am to lunch time by 12:00 pm is 6 hours.
Using the given formula in the hint: number of cells = 2^(ab) × C
Where a = number of times per hour the bacteria reproduces; b = number of hours; C = number of bacteria at the start
a = 60 minutes/ 20 minutes = 3; b = 6; C = 10
Number of cells = 2^(3 × 6) × 10
Number of cells = 2621440 cells
The technology time for the maximum not unusual place bacteria is pretty short, approximately 20 mins to one hour. The number of bacteria cells did have for lunch =2621440 cells.
Bacteria reproduce via way of means of binary fission, wherein the discern molecular divides into a time of the bacterial species is 20 mins.The time which has handed from among the time the sandwich became packed at 6:00 am to lunchtime via way of means of 12:00 pm is 6 hours.Using the given formulation withinside the hint: range of cells =2^ (ab)×C.Where a = range of instances in step with hour the reproduces; b = nu of hours; C = number of bacteria on the start.a = 60 mins/ 20 mins = 3; b = 6; C =10.The number of bacteria cells did have for lunch =2621440 cells.What is bacterial cel?Bacterial cells are exceptional from plant and animal cells. Bacteria are prokaryotes, because of this that they haven't any nucleus. A bacterial includes Capsule.
Thus it is clearly explained above that the number of bacteria cells did have for lunch =2621440 cells.

Rabbits in most areas have a brown coat. The arctic hare has a bright white coat in
winter. How does the arctic hare's white color help it survive?
Answer:
Indeed, rabbits, in most of the planet, tend to have their fur colored brown, copper or other similar shades. Now, in the Arctic regions, these animals do not have this color, but a white one, similar to the environment that surrounds them. This is so because these animals, for evolutionary reasons, have adapted their fur to the snowy environment that surrounds them in the Arctic, in order to avoid being detected by potential predators, protecting themselves and trying to ensure their survival.

_Cell division in prokaryotic cells is
a. Sexual
b. Asexual
C. Mitosis
d. Interphase
Answer:
it's binary fission
because --The cell division process of prokaryotes, called binary fission, is a less complicated and much quicker process than cell division in eukaryotes. ... The single, circular DNA chromosome of bacteria is not enclosed in a nucleus, but instead occupies a specific location, the nucleoid, within the cell.
At the end of Meiosis II, each daughter cell has 23 single-stranded chromosomes.
True
OR
False
Answer:
y the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. ... Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
Explanation:
30 chromosomes
Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2.
From a diploid germ cell 2n =24 double stranded chromosomes, meiosis will produce four gamete haploid cells n =12 single stranded chromosomes.
Meiosis produces four with half because double stranded chromosomes represents DNA replication. Twice as much DNA as a diploid cell needs.
From a diploid germ cell 2n =24 double stranded chromosomes, mitosis will produce two diploid daughter cells 2n =24 single stranded chromosomes for the same reason.
DNA replication doubles the genome before cell division. Sister chromatids of double stranded chromosomes represent the replicated DNA. During cell division, sister chromatids of double stranded chromosomes are separated into different cells.
Meiosis has two stages, the first separating homologous pairs of double stranded chromosomes, and then the second stage separating sister chromatids into four haploid (n) gametes.

What is the correct equation for the breakdown of ozone? please answer quick
Answer: This electricity converts the oxygen molecule to ozone. Our equation is as follows: 3O2 + energy = 2O3.
The correct equation for the breakdown of ozone can typically occur in a series of two steps known as the destruction of ozone. It is illustrated thus;
Cl + O3 ⇒ ClO + O2ClO + O ⇒ Cl + O2The net reaction of the above process is the reaction of an oxygen atom with an ozone particle to form two molecules of oxygen.
The catalyst in this reaction is chlorine because it undergoes changes as the process continues while ozone is removed in the process. In the presence of sunlight, atomic oxygen is formed.
This entire process is referred to as the destruction of ozone.
