TUESDAY, JANUARY 19, 2021 What are the 8 taxons (levels) in order? What are the 6 kingdoms Taxons Kingdoms
Answer:
-8 taxonomic levels: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
- 6 kingdoms: Eubacteria, Archaebacteria, Protist, Fungi, Plantae, Animalia.
Explanation:
Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships, and assigning to each them a binomial name.
The categories where organisms are classified into are:
Domains are the highest taxonomic category in which living beings can be grouped or divided. There are three domains: archaea, bacteria, and eukarya.- The archaea domain is composed of prokaryotic unicellular microorganisms that lack a nucleus, nuclear membrane, and organelles, but they have a cell wall that protects the cell. These organisms are capable of inhabiting in places with extreme temperature, salinity, acidity, or pH, among others. They reproduce asexually.
- The bacteria domain is composed of a wide group of unicellular prokaryotic microorganisms with a simple structure and sized between 1 to 10 micrometers. These organisms lack a nucleus, nuclear membrane, and organelles. They only present plasmids and ribosomes. They have a cell membrane and a cell wall that protects the cell. Some of them can also present a capsule. They reproduce asexually.
- The eukarya domain is composed of all the unicellular or pluricellular organisms that have eukaryotic cells that characterize by having a well-defined nucleus surrounded by a complex biological membrane. They also present organelles delimitated by membranes. These organisms reproduce asexually and sexually.
Kingdom: Includes different phyla closely relates. The bacteria domain includes the Eubacteria kingdom. The archaea domain includes the archaebacteria kingdom. Finally, the eukarya domain is divided into four kingdoms: Protist, Fungi, Plantae, and Animalia. Phylum: Includes different classes closely related.Class: Includes different orders closely relates.Order: Includes different families closely relatedFamily: Includes different genera closely relatesGenus: Includes many species.

Are atoms and molecules alive? Why or why not?
(This is 7th grade science)
Answer:
No
Explanation:
Atoms and molecules are not alive as they do not exhibit all, or any, of the eight characteristics of life. Cell theory also states that a cell is the smallest unit of life, and atoms and molecules are much, much smaller than a cell — in fact, they make up cells.
Therefore, they are not considered living things.
I hope this helped you, and if you would like a more in-depth explanation, please let me know!
Answer:
Nope :))
Explanation:
Although molecules and atoms are both apart of something that is living, this doesn't mean a single atom or molecule can live on their own.

why do cells need to go through mitosis
Answer:
Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

During the cell cycle, the cell duplicates its genetic material. Moreover, also during this cycle, the cell synthesizes all materials required for its division.
The cell cycle can be divided into an interphase and a mitotic (M) phase.
The interphase is in turn divided into three phases: Growth 1 (G1) phase, Synthesis (S) phase and Growth 2 (G2) phase.
During the S phase, the cell duplicates its genetic material by a process called DNA replication.
During G1 phase and G2 phase, the cell grows and synthesizes all materials (i.e., proteins) required to enter into the M phase.

Answer:
The sebaceous glands are responsible for forming sebum
Explanation:
The fat glands are formed by acini and excretory ducts that are the bait formers.
These acini have a highly developed REG in their interior since they have a high protein coding, this is the reason that the acinar cells have a good basophilic color in H&E sections in MO.
As Earth revolves around the Sun, the number of daylight hours varies from place to place. In which location would the number of daylight hours remain constant?
( North Pole, Equator, Anartica, Prime Meridian)
Answer:
i think its the Equator im not that sure
The number of daylight hours will remain constant at : ( B ) The equator
As the earth continues to revolve around the sun, It brings about the changes in seasons ( winter summer, spring and autumn ). During each season the daylight hours varies slightly across each place. While
The equator receives sufficient sunlight which makes its daylight hours fairly constant as the earth revolves around the sun. also the temperature at the equator is warm all round the seasons.
Hence we can conclude that the number of daylight hours will remain constant at the Equator.

Please and don’t waste my time bu saying that you don’t know the answer. thank you :) I hope you have a nice day
Answer:
Plants exchange oxygen and carbon dioxide. The oxygen is used for respiration and is also a waste product of photsynthesis. The carbon dioxide is used for photsynthesis.
During the day time, the stomata of the plant will open to let the carbon dioxide in for photsynthesis. Cabron dioxide diffuses into the leaf down a concetration gradient. oxygen will leave the leaf down the concentration gradient.
This process is the gas exchnage of plants.
How stomata open: Stomata open during the dayby absorbing water vapor, become turgid and and open. During the night, the stomata becomes flaccid and floppy. this causes it to close.

Which disappears more rapidly from a population, a deleterious dominant allele or a deleterious recessive allele?
Answer:
Selection is a directional process that leads to an increase or a decrease in the frequency of genes or genotypes. Selection is the process that increases the frequencies of plant resistance alleles in natural ecosystems through coevolution, and it is the process that increases the frequencies of virulence alleles in agricultural ecosystems during boom and bust cycles.
Selection occurs in response to a specific environmental factor. It is a central topic of population and evolutionary biology. The consequence of natural selection on the genetic structure and evolution of organisms is complicated. Natural selection can decrease the genetic variation in populations of organisms by selecting for or against a specific gene or gene combination (leading to directional selection). It can increase the genetic variation in populations by selecting for or against several genes or gene combinations (leading to disruptive selection or balancing selection). Natural selection might lead to speciation through the accumulation of adaptive genetic differences among reproductively isolated populations. Selection can also prevent speciation by homogenizing the population genetic structure across all locations.
Selection in plant pathology is mainly considered in the framework of gene-for-gene coevolution. Plant pathologists often think in terms of Van der Plank and his concept of "stabilizing selection" that would operate against pathogen strains with unnecessary virulence. As we will see shortly, Van der Plank used the wrong term, as he was actually referring to directional selection against unneeded virulence alleles.
A deleterious dominant allele would disappear more slowly from a population compared to a deleterious recessive allele.
What is a deleterious dominant allele?In the case of a deleterious dominant allele, the individual possessing the allele will always express the negative trait associated with it, making it easier to identify and potentially select against. In contrast, a deleterious recessive allele may not be expressed in individuals who carry only one copy of the allele, as the normal copy of the gene can still produce enough functional protein to mask the effects of the deleterious allele.
As a result, the deleterious recessive allele can persist in a population as carriers pass the allele on to their offspring without showing any negative effects themselves. However, over time, the recessive allele may become more common in the population, increasing the likelihood of two carriers mating and producing offspring that express the deleterious trait.
