Answer:

C. Viruses use living cells to make new viruses

Explanation:

Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves. This can kill, damage, or change the cells and make you sick. Different viruses attack certain cells in your body.

A student wants to view a cell’s mitochondria. Which of the following microscopes would show a mitochondria’s internal structure
Olegator [25]

Answer:

Transmission Electron Microscope would show a mitochondria’s internal structure in the greatest detail

Explanation:

The TEM is used to visualise the internal structure of the cells. This works when an electron beam of light passes through the object or the sample, it shows a clear presence of the organelles inside the cell. The TEM uses the energetic electron which provides the morphological as well as compositional and crystallographic features of the cell. Its maximum potential is about 1 nanometre. Among the most powerful microscope for studying the internal organelles of the cell TEM is one.

Which claim is best supported by the information about scales and feathers?​
alexandr402 [8]

<u>Answer:</u>

Recent evidence suggest that feathers evolved from scales and suggest that 'feathers and pycnofibers' could be homologous.

<u>Explanation:</u>

  • One of the major difficult issue related to bird evolution is the evolution of feathers.
  • Feathers are considered as the most 'complex integumentary structures' which are found in vertebrates.
  • Evolutionary developmental biology suggests that the 'planar scale structure' is been modified for developing into feathers by 'splitting' to form web like structures.
  • Scales and Feathers consist of 'two distinct form of keratin' so it was thought that 'each type was exclusive skin structure' but recent study suggests that they are developmental expressions of same skin structures.

9. Consider the below Punnett square cross. Explain how you could use it to determine which parent
kogti [31]

Answer: The father determines the biological sex of a baby

Explanation: Human beings have two sex chromosomes, males have XY chromosomes whereas females have XX chromosomes. During fertilization, an egg from a woman fuses with a sperm cell from a man to form a zygote. Women have two X chromosomes (XX) and any point in time they can only release an egg bearing an X chromosome but males have one X and one Y chromosome, therefore they can either release a sperm cell with an X chromosome or a sperm cell with a Y chromosome. When an egg with X-chromosome fuses with a sperm cell with an X chromosome, the resulting baby is a female but when an egg with an X chromosome fuses with a sperm cell with a Y chromosome, the resulting baby is a male.

What makes the difference in both sexes is the Y chromosome from the man, therefore the father determines the biological sex of a baby.
