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.

Select all that apply Choose all features that confined the green algal ancestors of plants to water. Multiple select question. Higher levels of UV light on land Less water availability in a terrestrial environment The inability to produce chlorophyll in a high oxygen environment More predators in land-based ecosystems
Answer:
Higher levels of UV light on land
Explanation:
The algae began to appear because of the presence of ultraviolet light that was emitted by sunlight, this generated the increase in temperature of the waters, therefore under the glaciers the perfect climax was formed so that these could begin to emerge phenomena, not excessive sunlight, the great presence of oxygen, is what led to the appearance of these algae.

What is the function of the Calvin cycle?
I’m not sure someone helppp!!! Quickly please
Answer:
its the the first option
Explanation:
This is because plants fix carbon dioxide from the atmosphere through photosynthesis. They produce sugar for food from the CO2.
Answer:It would be A i believe
Explanation: The enzyme RuBisCO is an organic compound that incorporates carbon dioxide. The organic molecule is reduced in stage 2. RuBP, the enzyme that begins the cycle, is regenerated in stage 3 so that it can begin the cycle. In short, fixing six carbon atoms from CO2 requires six turns of the Calvin cycle.

2. Interpret Graphs As you move up the y-axis, is the rate of photosynthesis
increasing or decreasing? As you move along the x-axis to the right, is the light
intensity increasing or decreasing?
Answer:
It depends on the graph movement.
Explanation:
If the light intensity is present on the x-axis and the rate of photosynthesis is located on the y-axis, then both the rate of photosynthesis and intensity of light are increasing because the graph moves upward which means the rate of photosynthesis increases with the increasing of light intensity. So if you moves from upward to downward, the rate of photosynthesis decreases with the increasing of light intensity.

Energy in biology falls into two categories. Kinetic energy (aka cellular work) includes solute
transport, motion, and endergonic chemical reactions. Potential energy is the energy of position and
is an important tool to store energy in biology. Potential energy in biology includes covalent bonds
and chemical gradients. Which of the following is evidence of the potential energy of covalent
chemical bonds?
a
Triglycerides (CiaH36O2l3 store about twice as much energy as polysaccharides (CH2O)
All of the other choices are evidence of the potential energy of covalent bonds.
O Light and heat are released when cellulose (wood) is burned.
Exergonic hydrolysis of ATP powers motor proteins.
Answer:
A. Triglycerides (CiaH36O2l3 store about twice as much energy as polysaccharides (CH2O)
Explanation:
Energy, as stated in this question, can be of two types namely: kinetic energy and potential energy. Kinetic energy is the energy due to motion i.e the energy used to transport solute etc.
On the other hand, potential energy is the energy due to position like the energy stored in the covalent bonds of a molecule. Based on this question, the fact that triglycerides (a type of lipid) store about twice as much energy as polysaccharides (carbohydrate) is evidence that POTENTIAL ENERGY is stored in covalent bonds.

which of the following best explains why ptyalin is able to break down starches, but not protein?
a) proteins are too large to he affected by enzymes.
b) proteins are able to easily denature enzymes.
c) enzymes are proteins and cannot break down other proteins
d) enzymes are specific to their substrates
ptyalin or salivary amylase is able to break down starches, but not protein as enzymes are specific to their substrates. Thus, option D is correct.
What are the function of ptyalin ?Ptyalin or salivary amylase is a starch hydrolyzing enzyme secreted by the chambers of human salivary glands.
It is secreted in the mouth and hydrolyzes starch into maltose and isomaltose.
It also produce small amount of dextrins which is otherwise called as the limit dextrins.
About 30% of starch are digested in mouth region by the help of ptyalin.
To increase the production is to eat foods containing natural digestive enzymes, such as fresh fruits.
This enzyme can work in a room with a high pH but cannot work in stomach, due to high acidity level.
Thus, option D is correct.

Where are centrosomes (microtubule-organizing-centers) located in an animal cell?
Answer:
The centrosome, cytocenter, or cell center is unique to animal cells. It is close to the nucleus and is considered an organizing center for microtubules.
Explanation:
The centrosome is a nonmembranous organelle, present in all dividing animal cells. It is located near the nucleus, often surrounded by the dictyosomes of the Golgi apparatus. The structure consists of an interior zone where the diplosome appears, formed by two centrioles arranged perpendicular to each other. The microtubules emanating from the centrosome end up in the pericentriolar material, not the centrioles, and it is the pericentriolar material that initiates the assembly of the microtubules. Therefore, the main function of the centrosome is to nuclear and anchor the microtubules.

How does the numbers of phenotypes relate to genetic variation in a population?
Answer:
Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation. Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.

Answer:
The question is incomplete , as the options are not given. Here are the options.
A. Hyperplasia
b. Metaplasia
C. Dysplasia
D. Anaplasia
The correct option is b.
Metaplasia
Explanation:
This because metaplasia is the process where by one mature cell can be replaced by another cell in the body. This is a reversible replacement that take place in the cell of the body. In this kind of replacement, a less differentiated cell replaced the mature cell. It occur when normal columnar ciliated epithelial cells of the bronchial lining have been replaced by stratified squamous epithelial cells.
