What might happen to a species if it has to compete for natural resources

1 answer:

3 0

Competition between species in an area of limited resources can have several consequences. On the extreme end, extinction could occur, but more likely there will need to be some adaptation by the species. Sometimes species find a way to share resources, other times a species may have to move to an area with more resources. This can disrupt the population and overall function of an ecosystem. If a species has limited resources it can also limit the opportunity for species growth and evolution.

A very common type of red–green colorblindness in humans is caused by a mutation in a gene located on the X chromosome. Knowing

Harrizon [31]

Answer:

50%

Explanation:

According to the given information, the allele for the red-green colorblindness is inherited in an X linked recessive manner. Let's assume that the allele X^c is responsible for red-green colorblindness. The woman is normal but had a colorblind father (X^cY). Fathers give their X chromosomes to the daughters while their Y chromosome is transmitted to their sons. The sons get their X chromosomes from the mother.

The colorblind father has transmitted the X-linked allele for the red-green colorblindness to his daughter. Therefore, the genotype of the woman is X^cX. The woman would produce two types of eggs: 50 % with X^C and 50% with X. Therefore, 50% of sons of this woman would get X linked allele for the red-green colorblindness and would be affected by the disorder while the rest 50% of her sons will be normal.

To solve a problem using the equation for Kepler’s third law, Enrico must convert the average distance of Mars from the Sun from

vovikov84 [41]

Answer:Enrico must multiply the distance of mars from sun (meters) with the $6.6844\times 10^{-12}$ to convert the distance in astronomical units.

Explanation:

1 astronomical unit = $1.496\times 10^{11} m$

$1m=\frac{1}{1.496\times 10^{11} } AU=6.6844\times 10^{-12} AU$

Let the distance between the sun and Mars be Y( meters)

Distance in AU= $Y\times 6.6844\times 10^{-12} AU$

Enrico must multiply the distance of mars from sun (meters) with the $6.6844\times 10^{-12}$ to convert the distance in astronomical units.

Photosynthesis requires a supply of CO2 as well as H2 O and sunlight. How do plants obtain these resources? (Hint: refer to plan

Triss [41]

Answer:

CO2 is supplied by mammals and other living animals exhaling, producing CO2 this is absorbed through their leaves, and stems

H2O is supplied by the water cycle, nearby rivers, oceans, creeks etc. This is soaked up through their roots. Excess sugars are also stored in the roots as food.

Sunlight is provided in the atmosphere and the chlorophyll absorbs this.
