Answer:

The correct answer is Eukaryotic Cells.

Explanation:

Eukaryotic cells are cells that have a <u>"true" nucleus attached to the membrane</u> where DNA, membranous organs and chromosomes are found.

Its size is larger than that of prokaryotic cells, and it also has a plasma membrane, ribosomes and cytoplasms.

Not only does the DNA lodge in the nucleus, but also the synthesis of proteins and ribosomes. Within this nucleus we find chromosomes, which are formed by the genetic material (DNA) in highly organized linear structures. <u>Most of the genetic information of a living being is housed there.</u>

What three processes lead to variation among offspring that have the same two parents?
beks73 [17]

Explanation:

Genetic variation in offspring during sexual reproduction is caused by

  • crossing over
  • independent assortment
  • randomized fertilization

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.

  • crossing over:  the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.
  • independent assortment in metaphase I of meiosis: chromosomes align independently and genes segregate independently into new combinations ...in humans 2n, n = 23, 8 million combinations of chromosomes possible
  • randomized fertilization: sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

dexar [7]

A lysosome is a membrane-bound sac found in cells that contains digestive enzymes which break down complex molecules or structure.

Lysosomes are single membrane organelles or vesicles  that  contain enzymes and are  specialized to breakdown complex food materials  such as sugars and proteins, into simpler substances.

Lysosomes are made in a process that begins in the endoplasmic reticulum and ends in the Golgi apparatus which puts the finishing touches to the lysosome before releasing it into the cytoplasm where it floats freely until engaged.

Which of the following statements is correct?
Keith_Richards [23]

Answer:

The statement that is correct is that all cells have the same genes, but different genes are active in different cells.

Explanation:

Differentiation or specialization is a function that cells possess and is what allows them to have different types of cells and tissues.

Cell differentiation depends on genetic regulation, a mechanism that determines the specific genes that are expressed in a cell or tissue type.

All cells contain the same DNA, which is organized into chromosomes and contain the genes that determine specific characteristics. <u>There is cell differentiation because some genes can be expressed and others are suppressed, all due to genetic regulation</u>.

The other choices are wrong because:

  • <em>The eyes look different from the liver, because they have the same genes, but only some are expressed. </em>
  • <em>Differentiated cells and tissues do not lose their genes. </em>
  • <em>All cells have DNA.</em>

Based on the diagram below, which part of an atom has the greatest mass?
Juli2301 [7.4K]
The nucleus will have the greatest mass. Among the 3 kinds of subatomic particles, electrons are the lightest (by several orders of magnitude), protons and neutrons are much closer is magnitude, though neutrons are slightly heavier. However, in the diagram, the nucleus contains both the neutrons and the protons, so its combined mass would be heavier than either the neutrons alone or the protons alone.
