1 the genetic material made from either DNA or RNA, long molecules that carry genetic information
2 a protein coat, called the capsid, which surrounds and protects the genetic material; and in some cases
3 an envelope of lipids that surrounds the protein coat when they are outside a cell. The shapes of these virus particles range from simple helical and icosahedral forms for some virus species to more complex structures for others. Most virus species have virions that are too small to be seen with an optical microscope. The average virion is about one one-hundredth the size of the average bacterium.

If a cat normally has 38 chromosomes in its somatic (body) cells, how many chromosomes will be in its gametes? a. 76 b. none of

<h3>What are the type of cells in the organism?</h3>

The types of cells in the organism are somatic and germ cells.

Both the somatic and germ cells go through mitosis producing two daughter cells with the same genetic dotation.

Somatic cells are any cell in the body except sperm and egg cells. They are diploid, meaning they contain two chromosome sets, each one inherited from each parent.

Germ cells are diploid reproductive cells. They suffer mitosis to form more sexual cells, and a few suffer meiosis to produce haploid gametes. Each germ cell produces 4 haploid gametes.

Each gamete has half the number of chromosomes of the somatic cell. Hence, cats' gametes will have 19 chromosomes. Option C.

Does any landform on Earth’s surface look the same as it did 5 million years ago? explain why or why not.

Sophie [7]

Answer:

Earth's surface didn't look much different. With few exceptions.

The global climate is cooler and drier, and seasonal, similar to modern climates. As the climate began to cool down grasslands continued to expand and forests started to dwindle in extent. In the seas, kelp forests made their first appearance and soon became one of Earth's most productive ecosystems. Water from the Atlantic Ocean poured in through the Strait of Gibraltar to deluge the Mediterranean Basin. The event is called the Zanclean flood. Parts of of southern Norway and southern Sweden that had been near sea level rose to form the Hardangervidda plateau and the South Swedish highlands.

Shorty after, the glaciations, uplift of the Rocky mountains and Panama seaway closure began to reshape the Earth.
