<span>The answer is c. Chromosomes carry the codes for hereditary traits. Chromosomes are thread-like structures made of proteins and DNA. Codes for hereditary traits are present in a molecule of DNA. Chromosomes can be found in the nucleus of each cell. Humans have 46 chromosomes in each cell (not 460) arranged in 23 pairs (not 230). Hope this helps. Let me know if you need additional help!</span>

Answer:

The correct answer is option c.

Explanation:

Chromosomes refer to the compositions found within the nucleus of the cell that comprises genes of an individual. The genes refer to the DNA segments, which comprises the code for a particular protein, which functions in one or more kinds of cells in the body.  

A chromosome comprises thousands of genes, and each of the normal human cell comprises 23 pairs of chromosomes, thus, a sum of 46 chromosomes. More than one gene present within a chromosome determines a trait known as a gene-determined characteristic. This trait or characteristic passes from one offspring to another. Thus, it can be said that the chromosomes carry the codes for hereditary traits.

-The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

The levels of organization are dependent on each other, for example, the organ systems rely on each other for many different things and cannot function without the other. e.g. The nervous and endocrine systems control the activities of the digestive, excretory, circulatory and respiratory systems. Organ systems need to work together to maintain homeostasis in the body.

What is the probability that a cross between a true-breeding pea plant with spherical seeds and a true-breeding pea plant with w
notsponge [240]

Answer:

1 or 100%

Explanation:

Let the allele for seed shape be represented by S.

True breeding spherical shape seeded pea plant will have SS as genotype

True breeding pea plant with wrinkled seeds will have ss as genotype

Crossing the two:     SS  x   ss

Progeny: Ss, Ss, Ss, Ss

Based on the assumption that spherical shape allele is dominant over wrinkle shape allele, all the F1 offspring will have spherical seeds.

<em>Hence, the probability is 1 or 100%</em>

What type of stellar object will the sun end its life end
Lerok [7]
Your wording is a bit confusing, but I get what you're trying to say.

Here's what the life cycle of a star looks like.

Stars begin as giant balls of hydrogen colliding together and releasing a ton of energy. This hydrogen will eventually fuse together to form helium, and once all of the hydrogen has become helium, This helium will, after a very long time and under lots and lots of pressure, form carbon. When this happens, it is considered a red giant, and the star becomes bigger and less bright. The star will become less and less bright and eventually start to shrink as all of that carbon turns to heavier elements like iron, turning into a dwarf star that eventually dies out.
(Dwarf stars are still shining are called white dwarf stars, and dead ones are black)

The cool part, though, is that massive stars (those which have a mass of at least 3 times the Sun's) turn into heavy elements so fast that the core collapses almost instantaneously and explodes violently into a ball of fire known as a supernova.

Sometimes the core of the star gets left behind, and either forms a neutron star or, if it has the mass of a massive star, will collapse in on itself and become a black hole.
