Answer:

Exceptions to Mendel's principles:

Does exceptions mean that Mendel was "wrong"? The answer is "NO". It means that we know more today about diseases, genes, and heredity than compared to what he expalined 150 years ago. Here I have summerized the exceptions with examples:

Incomplete dominance: When an organism is heterozygous for a trait and both genes are expressed but not completely.

Example: SnapDragon Flowers

Codominance: When 2 different alleles are present and both alleles are expressed.

Example: Black Feathers + Whites feathers --> Black and white speckled feathers

Multiple alleles: Three or more alternative forms of a gene (alleles) that can occupy the same locus.

Example: Bloodtype

Polygenic traits: more than one gene controls a particular phenotype

Example: human height, Hair color, weight, and eye, hair and skin color.

If an organism does not have its own means of locomotion and it produces new cells out of inorganic materials through the photos

Travka [436]

The organism is a plant.

Plants are photosynthetic and autotrophic organisms, characterized by plant cells containing chlorophyll. The plants do not have locomation devices and are therefore immobile.

Photyosynthesis starts from inorganic ingredients (CO2 and H2O) to give an organic molecule (glucose) and oxygen at the end.

Describe the relationship between gravitational force and distance as shown in the diagram below. SC.6.P.13.2

satela [25.4K]

Let's see the formula

$\\ \sf\longmapsto F=G\dfrac{Mm}{r^2}$

r is the distance
G is gravitational constant
M is mass of earth
m is mass of object.

Hence

$\\ \sf\longmapsto F\propto \dfrac{1}{r}$

If distance is more force is less .
If distance is less force is more.

Use a protractor to draw a parallelogram that has two side lengths of 5 inches and 2 inches and two adjacent angles that measure

Irina18 [472]

If the adjacent angles of a parallelogram measure 25° and 155°, the other two angles would measure 25° and 155°

<h3>What is a parallelogram?</h3>

A parallelogram is a quadrilateral (has four sides and four angles) in which both sides are equal and parallel to each other. Opposite angles of a parallelogram have the same measure and the diagonals are equal in length.

If the adjacent angles of a parallelogram measure 25° and 155°, the other two angles would measure 25° and 155° because opposite angles are equal.
