The Neanderthal copy of a gene crucial for language (FOXP2) more closely resembles the same gene in chimpanzees than in humans,
liraira [26]

Answer:

b. False

Explanation:

FOXP2 gene is required for language and speech development and is present in all animals. It is a transcription factor which encodes for a regulatory protein. Both modern humans and Neanderthals share FOXP2 gene which differs from chimpanzee version by two amino acids. Its the different regulation of the same gene which made modern humans more capable of  using language and speech. Neanderthals did use language rudiments but not completely constructed languages. There might be other speech genes involved too which differed between modern day humans and Neanderthals but not FOXP2.

Marco has experienced extreme fatigue (tiredness) lately. He eats three balanced meals each day and exercises 2-3 times per week
Kisachek [45]

Given the symptoms shown by Marcos, we can infer that the organelle that may be causing his problems is the mitochondria.

The mitochondria are one of the most famous and important organelle within a cell. Found in most eukaryotic cells, they are the organelle responsible for most of the energy production of a cell, and throughout the cells of the body, they become responsible for the energy production of the organism. This is the origin of its famous <em>"</em><u><em>Powerhouse of the cell</em></u><em>"</em> title. Mitochondria produce energy in the form of ATP.

ATP is a molecular compound necessary for most of the reactions that take place in a cell. It is so common as a requirement for any cellular activity that ATP is known as the "molecular currency". Marcos is said to be experiencing chronic fatigue, which is a symptom of mitochondrial disease. When the mitochondria of an organism's cells are not functioning as they should be, the cells do not have the energy needed to perform basic functions.

In reaction to this, the body sends signals to the brain to go to sleep, which minimizes energy consumption by slowing down the metabolic processes which require ATP and thus gives the body time to produce more energy. For these reasons, we can conclude that the fatigue and problems Marcos is experiencing are due to mitochondrial disease.

Kitty [74]

The birth rate was greater than the death rate and the immigration rate was greater than the emigration rate. Options B and D are correct.

<h3>Population growth</h3>

From the illustrated image, the world experienced an upward growth in population between 1950 and 2010.

In order for population growth to occur:

  • the birth rate must exceed the death rate
  • immigration must exceed emigration

Either or both of the above conditions will lead to a growth in the population.

Thus, options B and D are correct.
