How do we as humans reduce biodiversity AND in your opinion, why is it a big deal that we are? PLS HELP FOR A TEST
Answer:
We reduce Biodiversity (in animals) because we hunt them, and we hunt some more then others.
Explanation:
In my opinion, Its a big deal because animals impact is all. For example, if theres too many cows then there will be too little of grass, but if theres not enough cows then there'll be too much grass. If we take away all of the animals, then we will all starve, like how if we kill all the bees, there'll be no more plants. I hope this helps!

Which motion allows an observer on Earth to view
different constellations throughout the year?
A Earth orbiting the Sun
В. constellations orbiting Earth
C.Earth orbiting the constellations
D. constellations orbiting the Sun
Answer:
it’s A
Explanation:
Motion is defined as the change in the position of an object with respect to time. The motion can be uniform, non-uniform, retrograde, and circular.
The correct answer is:
Option A. Earth orbiting the Sun
The Earth is a celestial object that rotates and revolves around the Sun in a fixed orbit.
Also, the planets and other constellations in space revolve around the sun.
The retrograde motion is a type of illusion motion in which a viewer on the moving planet Earth observes the constellation, which is also revolving around the sun.
The retrograde motion occurs when the object moves in an opposite direction, such that Earth moves west to east, and the constellation moves east to west.
Therefore, option A is correct.

How many strands of mRNA are transcribed from the two “unzipped” strands of DNA?
Answer:
Since DNA is double-stranded, two different RNA molecules could in principle be transcribed from any gene, using each of the two DNA strands as a template.
Explanation:
During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA

Phytopharmaceuticals are pharmaceutical compounds that are found in plants. They can be naturally occurring or a result of biotechnology. Recently, scientists created genetically modified (GM) corn that produces the antibiotic penicillin. The seeds of this GM corn contain a large amount of the antibiotic penicillin, making the cost of producing the penicillin much cheaper and making the method of delivering it to patients in need much easier. Given the benefits of this GM corn, which of the following may be a concern regarding its production?
A.The GM corn may develop infections from bacteria that are sensitive to the antibiotic.
B.The GM corn might pass resistant genes to other organisms, like birds, that may eat the seeds.
C.Because corn uses the wind for pollination, people allergic to penicillin may be at risk for exposure to the antibiotic in the air.
D.Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
Answer:
The answer is D.Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
Explanation:
The correct option is Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
What are genetically modified crops?Through the use of laboratory procedures, genetic modification (GM) technology enables the transfer of genes for particular traits between species.
In the middle of the 1990s, GM crops were first made available in the U.S. The majority of GM crops being farmed in the U.S. have been modified to be herbicide or insect resistant. The three GM crops with the highest acreages are corn, soybeans, and cotton.
The technology has the potential to be used in the future to improve nutrition, stress tolerance, disease resistance, biofuel efficiency, and the cleanup of polluted places.
The U.S. Department of Agriculture (USDA), the Environmental Protection Agency (EPA), and the Food and Drug Administration (FDA), each with the ability to regulate particular parts of the crops, are in charge of regulating GM crops at the federal level.
Therefore, The correct option is Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.

Name two systems and explain how they
interact in the carbon cycle.
Answer:
Carbon leaves the hydrosphere and enters the geosphere when sedimentary rocks form on the ocean floor. Ocean water can warm and release dissolved CO2 directly into the atmosphere. As carbon moves through Earth systems, the total amount of carbon in the carbon cycle remains about the same.
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone.

3.Abiotic factors affect the type and number of organisms that live in a particular ecosystem.
4.Biotic factors depend on each other for food, shelter, protection, and reproduction.
Answer:
2.Biotic factors are dependent on abiotic factors for food and protection.
3.Abiotic factors affect the type and number of organisms that live in a particular ecosystem.
Explanation:
An ecosystem is an environment that contains both living and non-living parts that actively interacts together.
The living part of the ecosystem is the biotic factors and the non-living parts are the abiotic factors.
The biotic components actively depends on the abiotic component for nourishment. This is exemplified through the process of photosynthesis. Also, the shelter of organisms are derived from the abiotic factors. The abiotic factors have significant impact on the type and number of organisms that live in an ecosystem.Where does food enter the blood vessels?

the starting molecule for glycolysis is
Answer:
The starting molecule for glycolysis is glucose.
Explanation:
I think this picture might show why ⬇︎
The starting molecule for glycolysis is glucose.
In the end, glucose is split into two pyruvate molecules through glycolysis. Glycolysis can be thought of as having two phases that take place in the cytosol of cells. Due to the use of two ATP molecules, the first phase is known as the "investment" phase, and the second phase is known as the "payoff" phase.
Glycolysis is crucial because it is the metabolic pathway by which glucose is converted into energy for the cells. For all living things, glucose is the most important source of energy. The majority of cells in the human body use glucose as their preferred fuel: Red blood cells can only fuel themselves with it.
