Does anybody have a presentation about Mendel's second law. Please I need it to do well.

Answers

Answer 1

Answer:

See the answer below

Explanation:

Mendel's second law of genetics is also known as the law of independent assortment of genes.

In this law, Mendel opined that genes are independently inherited. In other words, Mendel said that the factors that dictate the physical attributes of living organisms are inherited independently.

This means, for example, that the color of your eyes is independently inherited from the color of your skin, your skin color is independent of your hair color, etc.

Mendel was able to prove this law by performing a dihybrid cross using the pea plant.

A true-breeding plant that is dominant for round and yellow traits (RRYY) was crossed with another true-breeding plant that is recessive for wrinkled and green traits (rryy).

All the F1 offspring were round with yellow color and the cross was advanced to F2. The F2 plants segregated in the ratio of 3:1 for the round trait to wrinkled traits and also 3:1 for the yellow to green traits respectively.

The outcome was the same as carrying out a monohybrid cross for each trait independently. Hence, Mendel concluded that traits are inherited independently of each other.

Which statement is FALSE? A. Phototropism and geotropism are adaptations of plants that allow for survival. B. Tropism is the growth response of plants to their environment due to external stimuli. C. A plant's response to moonlight is phototropism while it's response to gravity is geotropism. D. A tropism that causes a plant to grow towards the stimulus is positive.

Answers

Answer:

A. Phototropism and geotropism are adaptations of plants that allow for survival.

Explanation:

Ideally, TROPISM is the growth response of plants to their environment due to external stimuli as rightly stated in this question. However, based on what stimulus the plant is responding to, there are different types of stimulus.

Phototropism (photo-light) is the response of an organism to a light source while Geotropism (geo- gravity) is the response of an organism to gravity. Hence, based on this question, a plant's response to moonlight is phototropism while it's response to gravity is geotropism.

Also, tropism can either be positive or negative depending on whether the response is towards the stimulus (positive) or away from the stimulus (negative). Therefore, the FALSE statement is "Phototropism and geotropism are adaptations of plants that allow for survival"

fulcrum and is placed 0.5 m from the resistance end of the lever. Calculate the MA of the

board.

Answers

Answer:

7

Explanation:

Mechanical advantage is given by the ratio of the distance of the fulcrum from the two objects of the system.

Here the boulder is [tex]0.5\ \text{m}[/tex] from the fulcrum and the mass at the other end of the lever is [tex]4-0.5=3.5\ \text{m}[/tex] from the fulcrum.

So, mechanical advantage is given by

[tex]MA=\dfrac{3.5}{0.5}\\\Rightarrow MA=7[/tex]

So, mechanical advantage of the board is 7.

How is editing the genetic code different from artificial selection?

Answers

Answer:

Editing genetic code is when you take something already born and editing its dna. Artificial selection is when you edit somethings dna before it's born.

Editing genetic code creates new trait in the species but artificial selection select the trait already present in the species.

What are genetic code editing and artificial selection?

Humans can transform a species' members through genetic engineering and artificial selection to make them better suited to human demands. The method for transformation, however, is distinct.

Artificial selection selects for existing qualities in a species, whereas genetic engineering develops new traits. Following the cutting of the DNA, researchers employ the cell's own DNA repair mechanism to add or remove fragments of genetic information.

Artificial selection differs from natural selection in that it refers to selection used by people to generate genetic change. When artificial selection is used, the characteristics or traits are modified.

Therefore artificial selection selects species having new traits already present and genetic code editing creates new traits.
