Answer:

Key molecules that contain carbon include proteins, nucleic acids, carbohydrates and lipids. Carbon is an integral part of many biological processes, including reproduction, photosynthesis and respiration. We often assume that life in other parts of the universe, if we ever find it, will be carbon-based.

What seems to be the major difference between a deciduous <br> forest and a coniferous forest
LUCKY_DIMON [66]
<h2>Answer:</h2>

Differences between coniferous and deciduous forest lie in their names.

<h2>Explanation:</h2>
  • One of the biggest differences between forests is in their names.
  • Coniferous means 'cone bearing,' and these are trees that have cones, like pine trees.
  • Most conifers are considered evergreens, because they never lose their leaves and are 'forever green,' regardless of the season.
  • Deciduous means 'falling off'.
  • Deciduous trees, on the other hand, lose their leaves each year, which are mainly comprised of trees such as oaks and maple trees.

Result: the difference lies in their name.

Explain how myopia and hyperopia are related to the lens focusing on the retina.
liq [111]

Answer:

In myopia the image is focused ahead of the retina. While in Hyperopia the image is focused beyond or behind the retina.

Explanation:

I'll start by defining the two key terms, Myopia and Hyperopia. Myopia is otherwise called short-sightedness. It is a condition where one cannot see the images of objects located far away from the eyes and tend to see images within a short distance from the eyes. Hyperopia on the otherhand is otherwise known as long-sightedness. It is an eye defect which manifests by one not seeing objects close to the eyes instead he or she see only objects far from the eyes. These two eye defects are a malfunction of the accomodation feature of the eye.

Normally when an object is viewed all the parts of the eye (the organ for vision) function to focus the image of that object on the retina but especially on a part of it called the *light spot*. This then translates the image to the brain using the optical nerve. The brain then interpretes what is being viewed

However in Myopia, images are focused ahead of the retina . This is as a result of the eyeball being too long in relation to the focusing power of the cornea and eye lens.

In Hyperopia on the other hand, images are focused behind the retina. This is by the diameter of the eye being too short or the cornea being too flat.

In conclusion, from the above stated points,it is glaring that Myopia and Hyperopia affect the lens's ability to focus images on the retina.

Alkaptoneuria is a recessive genetic disorder found among North American populations at a frequency of about 1 in 500,000 births
Dafna11 [192]

Answer:

The correct answer is - 1/41,493

Explanation:

Let assume the frequency of the two possible same allele genotype (dominant and recessive) in an inbred population is p and q. Then the frequency of heterozygotes (H) is denoted as:

2pq + 2pqF.  ( where F is the inbreeding coefficient).

The frequency of the two different hoozygotes in inbred population can be calculated as:

p2 + pqF and q2 + pqF. (Where p and q are the allele frequency of the dominant and recessive phenotype.

Given: Frequency of Alkaptonuria (q 2) = 1:500, 000

=> q = 1/707

p = 706/707 ( Approx values)

solution:

Inbreeding coefficient (F) = 1/64

Therefore,

Frequency of Alkaptonuria in second cousins= q 2 + pqF

= 1/500, 000 + (706/707 x 1/707) x (1/64)

= 1/500, 000 + 1/45, 248

= 1/41,493 (approx)
