The recessive gene for blood typing s...
Type O
Type A
Type B
Type AB
Answer:
Image result for what is The recessive gene for blood typing
Because A is dominant, that means your mother could carry a hidden O. If she does then when she gets pregnant, each child has a 50% chance of getting her dominant A and a 50% chance of getting her hidden, recessive O. If the child gets the O from mom and an O from dad, he or she will have an O blood type.

Which would be an autotroph in a grassland ecosystem?
A. monarch butterfly
B. prairie cordgrass
C. mallard duck
D. muskrat
Answer:
B. Prairie Cordgrass
Explanation:
100% on the quick check
Autotroph organisms are capable of producing organic compounds from inorganic sources, such as light. All plants are autotroph organisms. The correct option is B. prairie cordgrass.
Let us review the differences between autotroph and heterotroph organisms.
What is an autotroph organism?
Organisms that can take inorganic substances, such as light, and turn it into food according to their own needs are producers, and they are called autotrophic organisms.
These organisms are by excellence all plants, that photosynthesize.
Autotrophs aborb 1% of the energy that reaches the earth's surface. This small percentage of energy flows through all organisms in the ecosystem -from autotrophs to heterotrophs- until it dissipates in the environment.
What is an heterotrophic organism?
Organisms that are incapable of producing their food are called heterotrophic.
They depend on other organisms from the trophic chain such as plants or other animals to feed on, so they can get proteins and energy.
In the trophic chain, heterotrophic organisms occupy different levels after producers.
The prairie cordgrass is the heterotrophic organism.

Be sure to include the contributions of French chemists Marie Curie and Pierre Curie and the medical uses of radiation.
Answer:

Explanation:
On April 20, 1902, Marie and Curie with success isolate radioactive metallic element salts from the mineral uranium ore in their laboratory in Paris. In 1898, the Curies discovered the existence of the weather radium and metallic element in their analysis of pitchblende. One year once analytic radium, they might share the 1903 Nobel prize in physics with French soul A. Becquerel for his or her groundbreaking investigations of radioactivity.
Marie Curie was born Marie Sklodowska in Warsaw, Poland, in 1867. The girl of a physics teacher, she was a talented student and in 1891 visited study at the university in Paris. With highest honors, she received a degree in physical sciences in 1893 and in arithmetic in 1894. That year she met state capital Curie, a noted French man of science and chemist who had done vital add magnetism. Marie and Pierre married in 1895, marking the start of a scientific partnership that will accomplish world renown.

Which of the following processes cycles matter through different parts of an ecosystem?
More than one answer may be correct.
1. the nitrogen cycle
2. the water cycle
3. the carbon cycle
Answer:
the nitrogen cycle, the water cycle, and the carbon cycle
Explanation:
The water, carbon, and nitrogen cycles move nutrients through the different parts of an ecosystem. Water moves through organisms and the environment in different phases. Carbon moves through an ecosystem in carbon dioxide, minerals, and organic compounds. Nitrogen moves through an ecosystem in nitrogen gas, ammonium, nitrates, and organic compounds.
The biogeochemical cycle is a pathway that circulates the chemicals through the abiotic and the biotic factor. The nitrogen, water, and carbon cycle through various regions of an ecosystem.
What is a biogeochemical cycle?The biogeochemical cycle is the movement of the chemicals and compounds of carbon, nitrogen, and water in the biosphere (biotic) and the atmosphere, lithosphere, and hydrosphere (abiotic) spheres of the earth.
These cycles move the nutrient through different spheres in the form of inorganic and organic compounds. It is an essential part of the ecosystem as they regulate the flow of the natural elements.
Therefore, option 1. nitrogen cycle, option 2. water cycle, and option 3. carbon cycle move through various parts of an ecosystem.

The common North Carolina geological feature is pictured in the graphic below is river basin. Thus option A is correct.
What is river basin?River basin is defined as the amount of land over which surface run-off falls into the sea via streams, rivers, and lakes.
A drainage basin is defined as a section of land where all flowing surface water flows to a single place, such as a river mouth, or into another body of water.
River basin is also defined as an ecological phrase referring to the area of land surrounding a river from which all water drains.
It is the land area drained by a river and its tributaries
Thus, the common North Carolina geological feature is pictured in the graphic below is river basin. Thus option A is correct.

How do cells support the evolution theory?
Answer:
Hope this helps!
Explanation:
The endosymbiotic theory explains how eukaryotic cells evolved. The large and small cells formed a symbiotic relationship in which both cells benefited. Some of the small cells were able to break down the large cell’s wastes for energy. They supplied energy not only to themselves but also to the large cell.
The image below shows plant cells.
What feature of cells is best demonstrated in the image?
OA Cells are the basic units of structure and make up tissues.
OB. All organisms are made up of a large number of cells.
OC. All organisms have cells with different shapes and functions.
OD. Cells are formed from other cells within the same tissue.

You are working in a lab trying to identify a single celled organism. You are not
sure if it is a Protist or a Moneran (Eubacteria or Archaebacteria). What test
would be most useful to determine its identity?
A. Put it in the sun and measure the oxygen levels
B. Determine if it is motile
C. Test its cells for chitin
D. Determine if it has a nucleus
The test that will be most useful to determine the identity of the single-celled organism is to "determine if it has a nucleus".
DIFFERENCE BETWEEN A PROTIST AND MONERAN:
A protist is a member of the kingdom protista characterized by it's single cells and eukaryotic nature.
On the other hand, a MONERAN is a member of the kingdom MONERA and characterized by it's unicellular and prokaryotic nature.
The major difference between Monera and protista is their prokaryotic and eukaryotic cells respectively. Prokaryotic cells do not have a membrane bound nucleus while an eukaryotic cell does.
Since the major difference between Monerans and protists is their possession of a membrane bound nucleus, the identity of the single-celled organism is to "determine if it has a nucleus".

Darwin proposed as the process that causes evolution to occur.
Answer:
natural selection
Explanation:
Darwin proposed natural selection as the process that causes evolution.
According to the theory of natural selection, the environment naturally selects for genes that confer fitness to organisms over every other gene. In other words, organisms that are able to adapt to an environment survive and contribute more to the subsequent generation while those that are poorly adapted contribute less and gradually fade away from the population.
For example, when a drug is taken a particular pathogen, the susceptible ones among the pathogen's population will die off while the ones with the resistance gene survive, reproduce, and pass on the resistance gene to the subsequent generation. Consequently, the same drug might not work at all for the new generations of the pathogen because the gene that confers fitness has been selected for.

Natural Selection
