Which describes a Mendelian trait?A. Blood type in humans has several
different alleles.
B. Plants can grow to a wide range of
heights.
C. Humans either have attached
earlobes or detached earlobes.
D. Human body mass is controlled by
many genes.

Answers

Answer 1
Answer:

The Mendelian trait are those controlled at only single gene locus. The Mendelian trait have two alleles (one form each parent), out of which one allele is dominant while the other is recessive. The dominant allele will express in both homozygous and heterozygous conditions while the recessive allele will express itself only in homozygous condition. An example of the human Mendelian trait is the attached or detached earlobes. A human will either have attached earlobe or detached earlobe.

Hence, the correct answer is 'Option C - humans either have attached earlobes or detached earlobes'.
Answer 2
Answer: The correct answer is C. (Ik it's correct because I just answered it)

Answers

1. The correct answer is C. The Mason- Dixon Line has been designed as a National Historic Civil Engineering Landmark.

Main clause can also be referred to as independent clause. There is a verb and a subject in it and they express a thought which is complete.

2. Correct answer is C. Which is perhaps the most famous border which is ever established by surveying methods.

Subordinate clause can also be known as dependent clause. It starts with relative pronoun and it has both verb and subject. A complete sentence can not be formed in this combination.

3. The correct answer is adjective.

Subordinate clause functions the same way as adjective.

How and why do cells reproduce

Answers

Cells reproduce for 3 reasons

-Repair
-Growth
- And to make new kinds of cells

And how they reproduce

Scientists call the process of somatic cell division mitosis. Mitosis has six distinct steps in which the cell organizes and copies the DNA in the nucleus. Once copied, each new cell has its own copy of the DNA. The six steps of mitosis are prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis. Some authorities consider the non-dividing portion of the cell’s lifecycle, known as interphase, to be one of seven steps involved in mitosis; however, interphase cells are not actively dividing. Sex cells, such as sperm or eggs, must divide differently. Sex cells only possess one-half of the DNA that makes up a new animal. That way, when they combine, the resulting organism gets half of its DNA from its mother and half from its father. Because sex cells only want half of the DNA in each cell, they go through a different division process called meiosis. In meiosis, the cells split a second time, which yields four daughter cells rather than two as with mitosis; however, this provides each daughter cell with 23 chromosomes in contrast to the 46 chromosomes in somatic cells.

Using what you've learned about the nucleus, how could you identify it by looking at a cellthrough a microscope.

Answers

It may be the largest organelle in the cell, filled with dark-colored chromatin. You won't be able to see the DNA with a school microscope, but you can see the chromatin, which will look like Ramen noodles.

Natural selection is an evolutionary mechanism by which:. A. Advantageous traits are eliminated in a population
B. Advantageous traits become more common in a population
C. Inherited traits pass consistently through generations
D. Organisms choose which traits to look for in their offspring

Answers

The correct answer would be option B

Natural Selection is a phenomenon in which the the traits that is advantageous for the population is common in a population.

These changes evolve over a period of time. The organisms having some change in the characters due to mutation survives and the organism lacking these features die.

These characters are then transferred from one generation to another and becomes common in a population.
The correct answer is B. Natural selection occurs through generations and is in which organisms best suited to their environment survive.
