The independent assortment of genes is a principle of Mendel and of genetics. Since humans are diploid organisms (they have 2 copies of their genetic information), we have that each gamete carries one of the two available alleles for each feature. These gametes are created in equal proportions.
We have that both parents are heterozygous for a feature, lets say H. Thus, their genotype is Hh. Hence, the child will get with probability 50%=1/2 H from the father and 50%=1/2 h from the father; same from the mother. By doing a Punnett square, we get that there is 1/4 chance that the child is HH, 1/2 chance that it is Hh and 1/4 that is hh. Since the disease is recessive (so both alleles are needed), we have that the chance that the kid has the disease is 1/4.
Answer:
it reflects green light and absorbs other colors.
Explanation:
The term pigment derives from the Latin pigmentum, which means the <em>substance that produces color</em>.
Pigments provide color to cells and tissues.
In vegetables, we can find different pigments, such as chlorophyll or carotenoids, among others. Plants use these pigments during the photosynthesis process to absorb sunlight and fixate carbon dioxide. Stem, flowers, and other tissue have pigments in their cells that define the organ´s colors.
Pigments are chemical molecules that produce color by the selective absorption of sunlight. Whenever white light meets a pigment, some wavelengths are absorbed by the pigments while others are reflected. The color expressed is the product of the reflection. The reflected spectrum is perceived as color and determined to be the pigment color or the color of an object or organism.
The color that tissue or vegetal organ express will depend on the pigment concentration or the combination of many of them.
The green color is ordinary in most vegetable species. Chlorophyll is responsible for this coloration, present in almost every vegetable species. This pigment absorbs blue and red wavelengths. But they reflect spectrums of green wavelengths, meaning that the expressed color is green in different tones.
No, the biodiversity is not as high in a city park as it is in a farm or rainforest
because, in an urban city park, only the species with the most general habitat and resource requirements have generally remained in the urban park.
<h3>What is Biodiversity ?</h3>
“Biodiversity” not only refers to the number of individual species, but also the genetic variety within and between species and the diversity of ecosystems and regions.
- City Parks are less likely to have biodiversity richness as compared to a farm or a rainforest.
- This is because these parts are artificially created and a lot of naturally occurring flora and fauna are modified in the process. This results in dilution of biodiversity-rich place.

The correct option is D.
The gasoline fuel used inside the car has inherent potential energy in its molecules. When the car is started, this potential energy will be converted to heat energy. The heat energy will then be used to carry out mechanical works in the engine of the car, this makes the car to move forward. At the point of moving, the energy in the car has been transformed to kinetic energy, which is energy in motion.
Answer:
Hydrogen bonds provide higher surface tension to a liquid. If you disrupt hydrogen bonds, surface tension will decrease. That's why at high temperature, surface tension is lower due to disruption of hydrogen bonds. Hydrogen bonds can be disrupted by the addition of surfactants and surface tension can be reduced also. Detergent is a surfactant because it interferes with the attractive forces between the water molecules.
