Answer:
All organisms, both prokaryotes and eukaryotes, can replicate cells by mitosis.
Explanation:
Mitosis is the process of cell division where, from a progenitor cell, two identical daughter cells are obtained. In the human being this process is carried out by somatic cells.
Cell division by mitosis is carried out by all living beings:
Prokaryotic organisms, unicellular, use it as a means to reproduce. Eukaryotic organisms, most of them pluricellular, use it in the processes of growth, development, repair and regeneration of tissues.All living beings can perform mitosis as a process of cell replication, although with different objectives.
1. The parts of the flower involved in reproduction are ________ and __________
2. The anthers bear the ___________the microspore mother cells give rise to _______or pollen grains after meiotic cell division.
Answer:
1. Stamen and pistil
2. Pollen, microspore
Explanation:
The flower is the reproductive part of certain plants called ANGIOSPERMS. They make use of their flower for sexual reproduction. The different parts of the flower work together to achieve a common goal, which is to reproduce, however, they do it in various ways. For example, accessory parts like petals attract pollinators. The major parts of the flower that are directly involved in the reproductive act are STAMEN (male) and PISTIL (female).
The stamen which constitutes a structure called ANTHER bears the pollen grains or microspore, which is made when the microspore mother cells undergo meiotic division. Hence, the pollens are released from the anther of a male flower (stamen), into the stigma of the female flower (pistil).

What TWO things cause denaturation of enzymes:
suggest two factors other than the rate of nitrogen fixation that may affect the avality of nitrogen in the marine ecosystem
Answer: run off from land/rivers and phytoplankton blooms
Explanation:
Nitrogen, particularly as nitrate is easily leached from soil. Human agriculture relies on fertilisers with significant nitrate content that applied at levels higher than it can be used. The balance end up as runoff, much of which ends up in
The two factors that are other than the rate of nitrogen fixation that fit the marine ecosystem are runoff from the land or rivers and the phytoplankton blooms
Waht is nitrogen fixation ?Nitrogen fixation refers to the chemical process by which molecule N2 has a strong Tripple covalent bond and in the air, it gets coveted into NH3 or a related nitrogenous compound that is typically in soil or aquatic system.
The fixation is essential for life as inorganic nitrogen compounds are needed for the biosynthesis of nitgen-containing organic compounds like amino acids.
As nitrogen is easily found in soil and can be added by fertilizers it ends as runoff and damages the ecosystem.

Answer:
Red
Explanation:
Blue light has a shorter wavelength than red.
Often in laboratory experiments you will want to amplify regions of the genome from several different preparations of gDNA. To do this, a mastermix will be created with all the common reagents to ensure easier pipetting, proper mixing, and controlling for variations in pipetting. Create a mastermix for running 8 identical reactions, including one negative control, each with different gDNA templates (7 total gDNA templates).
Answer:
Mastermix in PCR helps in providing faster and easier setup with pipetting, proper mixing, reduction in contamination and controlling fir variation in pipeting or tube to tube variability. Contents of PCR master mix for the desired reaction are as follows:
dNTPsPrimersthermostable DNA polymerasecofactor (MgCl2)Template DNA (for 7 samples)PCR-grade waterThe only difference in negative control for the PCR master mix is template or the different primer rest the components are the same in the master mix.

Cells that are terminally differentiated:_________
a. will undergo apoptosis within a few days.
b. can no longer undergo cell division.
c. are unable to move.
d. no longer produce RNAs.
Answer:
b. can no longer undergo cell division.
Explanation:
Terminally differentiated cells are those cells completely specialized in their functions that have lost their ability to proliferate. They are cells that have a unique, very specific, function, whereas undifferentiated cells do not have specialized functions that serve to replace old and dead cells. Examples of terminally differentiated cells include skin cells derived from epithelial stem cells, red blood cells and white blood cells generated from hematopoietic stem cells, etc.

Explain how matter is cycled between plants and animals.
The food of come from autotrophic plant to animal through food chain. The energy cycles between the air and soil and plants, animals, and microbes occur by food web.
What are the components of food web?A food web is defined as the cyclical event of energy transfer among different trophic level of organism.
The major components are primary producers, primary consumers, secondary consumers, tertiary consumers, quaternary consumers
Primary producers are the green autotrophic plants and capture some of the solar energy and convert it into chemical energy by photosynthesis.
The net primary productivity (NPP) of energy is defined as the rate of photosynthesis minus the rate of respiration of plants.
Primary consumers or herbivores feed on producers constitute the second trophic level of the food web.
in third tropic level, Secondary consumers eat primary consumers where as tertiary consumers, quaternary consumers or predators, carnivores or omnivores, which are both plant- and animal-eaters, such as humans.

Explanation:
Assume it takes Venezuela 3 hours to produce a batch of apples and 7.5 hours to produce a batch of pumpkins, and it takes the United States 3 hours to produce a batch of apples and 8.5 hours to produce a batch of pumpkins. Which nation has an absolute advantage in producing pumpkins?
The nation with an absolute advantage in the production of pumpkins would be Venezuela.
In economics, absolute advantage refers to the ability of an entity to produce a good or service at a lower cost/time per unit given the same resources as another entity.
In other words, given the same quantity of input and time, an individual, a company, or a nation that produces greater output over the other has an absolute advantage at producing such an output.
Hence, if it takes Venezuela 7.5 hours to produce the same batch of pumpkins that the United States produces in 8.5 hours, then, Venezuela has an absolute advantage in producing pumpkins over the United States.
