Yes, it’s possible. The genetic that they give out to their children depends. If the parents gives out the genes for colorblind for the daughter but not the son, it’s possible.

It’s just like having a child with disabilities and another child that is perfectly healthy.

2. In sheep black wool is recessive to white wool. What happens when you mate a black ram (male) to a heterozygous ewe (female).
sveta [45]

Answer:

50% will be white (Ww) and 50% will be black (ww)

Explanation:

Here's what the punnett square should look like.

In order for the black ram to have its coloring it would need to have 2 recessive genes (ww). The female is heterozygous, meaning she carries both genes (Ww) but only exhibits the dominant gene, in this case white fur (though they can pass the recessive gene on to their children). Simply filling out the punnett squares shows the outcome of the offspring.

Marrrta [24]
<h2><em>Lamarck's Theory of Evolution</em></h2>

Explanation:

  • <em>Lamarck's theory of evolution</em> was based around how living beings<em> (for example animals, plants)</em> change during their lifetime, and then pass these progressions onto their offspring
  • The model used to explain the concept of <em>utilization and neglect is the stretched neck of the giraffe</em>
  • As indicated by Lamarck's hypothesis, a given giraffe could, over a lifetime of stressing to arrive at <em>high branches, build up a lengthened neck</em>
  • <em>The development of long neck in giraffes is an example of Lamarck's theory of evolution</em>

Which statement describes an event from the light-dependent stage of photosynthesis?
defon

The correct answer is option 4, that is, ATP and NADPH are produced.  

The light-dependent reactions refer to an array of biochemical reactions in the process of photosynthesis, which need light energy that is captivated by the light-absorbing pigments like chlorophyll. The light-dependent reactions occur in the thylakoid membranes of the chloroplast.  

The light-dependent reactions use energy in the form of light to produce two molecules required for the next phase of photosynthesis, that is, the energy storage molecule ATP and the reduced electron carrier NADPH.

larisa86 [58]

Regrowth of grasses, ferns, wildflowers, and saplings after a forest fire is an example of secondary succession.

Secondary succession is one of the two main forms of ecological succession of plant life that is initiated by an occurrence such as harvesting, or forest fire, that has a negative impact or diminishes  an already established ecosystem such as a forest or a wheat field to a lower number of species. Several factors such as initial composition, trophic interaction, and competition-colonization trade-offs can influence secondary succession.
