In beta fish, a blue tail (B) is dominant over a black tail (b) and a metallic sheen (M) is dominant
over no metallic sheen (m). A female beta fish who is heterozygous for blue tail with no metallic
sheen has offspring with a male who has a black tail and has no metallic sheen. What is the
phenotypic ratio of their offspring?
Answers
Answer:
D) 8 blue tail nonmetallic: 8 black tail nonmetallic
Explanation:
The first thing to realize about the problem is that all offspring will be nonmetallic. Both parents are pure recessive for nonmetallic tails; therefore, their offspring cannot have metallic tails. So to find the ratio, use a simple punnet square with Bb and bb. This results in a 50% chance of Bb (blue) and 50% bb (black). So the last answer is correct.

QVII) Give reason for the following:
1. Light travels in a straight line
Answers
Shadows are evidence of light travelling in straight lines. An object blocks light so that it can't reach the surface where we see the shadow. Light fills up all of the space before it hits the object, but the whole region between the object and the surface is in shadow.
Explanation:
Since the wavelength of light is very small as compared with the size of ordinary object and diffraction of light is not easily noticed and hence the light appears to travel in a straight line.

In base pairing for the translation of DNA to mRNA, which nitrogen base complements Adenine?
Answers
Answer:
Adenine and thymine form base pairs that are held together by two bonds, while cytosine and guanine form base pairs that are held together by three bonds. Bases that bond together are known as complementary. During transcription, DNA is converted to messenger RNA (mRNA) by an enzyme called RNA polymerase.

d.
the number of plants will increase, the number of grasshoppers will increase, the number of snakes will increase
Answers
Answer:
The answer is A
Explanation:
The number of plants will decrease, the number of grasshoppers will increase, the number of snakes will decrease.
What is Food chain?Everything that is alive, from microscopic algae to enormous blue whales, depends on food to thrive. Each food web represents a possible route for nutrients and energy to travel through the ecosystem.
As an illustration, grass makes its own sustenance from sunshine. A bunny consumes some grass. Eaten by a fox, the rabbit. When a fox dies, microbes decompose its remains and return it to the soil, where it feeds grass-like plants.
Grass is consumed by a wide variety of animals, and rabbits can also consume other plants besides grass. Foxes can consume a wide variety of animals and plants. These living organisms can all be found in different food chains.
Therefore, The number of plants will decrease, the number of grasshoppers will increase, the number of snakes will decrease.

Answers
Answer:

Explanation:
Answer:
A mutation that causes female pigs to have fewer offspring
Explanation:
In the farming industry, more product is better. If cows produced more milk, farmers would make more money.
If sheep produced more wool, the farmers would profit.
If there was an increased crop yield, the farmers would benefit.
However, fewer pigs means less money, so that is the only possible answer.
