Option C is correct.
What do you mean by muscle cell?The cells that make up muscular tissue are referred to as myocytes or muscle cells.
No oxygen is used during anaerobic respiration, hence less energy is released. During intense exercise, the glucose molecule splits into two molecules of lactic acid, which accumulate in the muscles. When the bloodstream cannot provide oxygen quickly enough for aerobic respiration, anaerobic respiration takes place.

How would our interaction with the suns energy differ if our magnetosphere disappeared?
Answer:
Enveloping our planet and protecting us from the fury of the Sun is a giant bubble of magnetism called the magnetosphere. It deflects most of the solar material sweeping towards us from our star at 1 million miles per hour or more. Without the magnetosphere, the relentless action of these solar particles could strip the Earth of its protective layers, which shield us from the Sun’s ultraviolet radiation. It’s clear that this magnetic bubble was key to helping Earth develop into a habitable planet.

Which of Mendel's laws or principles explains that traits are passed from parents to offspring individually instead of as pairs, groups, or sets?
Answer:
the law of independent assortment
Explanation:
The law of segregation is the Mendel’s laws or principles explain that traits are passed from parents to offspring individually instead of as pairs, groups or sets. So the correct option is option “C” as far as the given question is concerned. This is a law or principle which states that during the formation of gametes, two copies of each heredity factors separate out so that the new offspring can get one factor of both the parents. This law was the first law in this direction.
A template strand of DNA contains nucleotides in the following proportions: 14% adenine
(A), 33% thymine (T), 21% cytosine (C), and 32% guanine (G). What can you expect
the proportions of the nucleotides to be in the newly formed complementary strand?
Answer:
The proportions of nucleotides in the newly formed complimentary strand will be:
14% Thymine (T), 33% Adenine (A), 21% Guanine (G), 32% Cytosine (C).
Explanation:
In a double stranded DNA, the nucleotides of one strand binds with nucleotides of another strand through hydrogen bonds.
Adenine binds with thymine by two hydrogen bonds (A=T) and guanine binds with cytosine by three hydrogen bonds (G≡C).
So, the complimentary strand must have
thymine equal to the amount of adenine in template strand.adenine equal to the amount of thymine in template strand.guanine equal to the amount of cytosine in template strand.cytosine equal to the amount of guanine in template strand.The picture below shows the structure of one type of organic molecule.

A river system is made up of a river and its a. sediments. b. divides. c. runoff. d. tributaries.
Answer:
A river system is made up of a river and its tributaries.
What is a river system?
A river system is a term used to describe the broader networks of streams, lakes, and rivers that are tributaries and distributaries of a larger river. For instance, the Mississippi River system includes the Ohio, Red, and Missouri rivers, all of which drain into the Mississippi River. Due to its interconnectedness, the condition of one river may have an effect on the health of the other rivers in the same river system. A river system can also include other types of terrain, such as the wetlands and flood plains that are affected by a major river and its tributaries and distributaries. The majority of the time, rivers have a primary source, such as snowmelt from a mountain that cascades into a number of streams, which eventually merge to form a river that empties into a much bigger river. This is an illustration of a river network. River systems are ecosystems from an environmental perspective, and if even one component of the system is contaminated or destroyed, it may have a severe impact on things like water quality and the health of plants and animals. For instance, the effects of high pollution levels or prolonged drought near a river's source will be felt throughout the rivers and lands that make up the river system.
An example of this is the Amazon River in Brazil (South America).
Answer:
A river system is made up of a river and its tributaries.

Where are chromosomes located during metaphase?
The mitotic spindle pulls the chromosomes together at the metaphase plate. Microtubules from opposite spindle poles grab the two sister chromatids of each chromosome. In metaphase, the spindle has collected all the chromosomes and lined them up at the middle of the cell, ready to divide.
What are chromosomes?Chromosomes are the greatest level of DNA and protein organization. Chromosomes' primary job is to transport DNA and genetic information from parents to offspring. During cell division, chromosomes play a vital role. They keep DNA from becoming twisted or damaged.
The metaphase plate is a plane or region that is about equidistant from a dividing cell's two poles.

Like DNA, RNA contains four nitrogenous bases. Three of them are the same as those found in DNA. The one that is different is called ________
The five-carbon sugar in RNA is called ________
Answer:
RNA has for nitrogenous bases out of which three are the same as DNA. The bases common to both DNA and RNA are Adenine (A), Guanine (G) and Cytosine (C). The one that is different is called Uracil (U).The five carbon sugar in RNA is called Ribose sugar.Explanation:
DNA consist of four bases that are A,T,C and G. Similarly, RNA also consists of four bases that are A,U,C and G.
Thymine (T) is not present in RNA, instead of it, RNA has Uracil (U) which binds with Adenine (A) by two hydrogen bonds.
The five-carbon sugar that is present in RNA is ribose and that present in DNA is deoxy-ribose. Ribose and deoxy-ribose differ at second carbon. Ribose has an OH at second carbon while in deoxy-ribose, O is missing at second carbon and it has only H.
