Which mutation would be harmful to the farming industry?
a mutation that causes cows to produce more milk
a mutation that causes sheep to have more wool
a mutation that causes female pigs to have less offspring
a mutation that causes an increased crop yield
Answer:
a mutation that causes female pigs to have less offspring
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.
specificity of communication by the nervous system compared to the endocrine system
Answer:
Like the nervous system, the endocrine system is a regulatory system. However, instead of using electrical impulses for signaling, it produces and uses chemical signals called hormones, which travel through the bloodstream and control the actions of cells and organs.

Consider the following food chain: Plants are eaten by grasshoppers, which are eaten by mice, which are eaten by snakes. In the short term, what will happen to the other members of the food chain if the mice were removed?
a.
the number of plants will decrease, the number of grasshoppers will increase, the number of snakes will decrease
b.
the number of plants will decrease, the number of grasshoppers will decrease, the number of snakes will decrease
c.
the number of plants will increase, the number of grasshoppers will increase, the number of snakes will decrease
d.
the number of plants will increase, the number of grasshoppers will increase, the number of snakes will increase
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.

How are the smallest ocean waves produced?
A.Weak winds that blow for short periods of time over great distances.
B.Weak winds that blow for long periods of time over small distances.
C.Weak winds that blow for short periods of time over small distances
D.Weak winds that blow for a long time over a great distance.
Answer: the answer is C
Explanation:
Answer:
c!
Explanation:
For a wave to effectively be produced there need to be large wind, long period of time and a large distance of water. If they are all reduced, then there would be a reduction in the intensity of the wave.

In base pairing for the translation of DNA to mRNA, which nitrogen base complements Adenine?
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.

Human decisions about controlling erosion have very little effect on living conditions.
True
False
Answer:
False
Explanation:
The main cause of man-made erosion is agriculture, followed by construction and mining.
Where humans once used sticks and stones, they have since developed technology that dramatically accelerated the speed of erosio.
Hence, if human descions are to control the soil erosion then there will be a very big impact on living conditions.

Two individuals that are heterozygous for tongue rolling mate. What are the predicted genotypic and phenotypic ratios for this cross?
Answer:
Genotypic ratio = 1:2:1
Phenotypic ratio = 3 tongue rollers : 1 non-tongue roller
Explanation:
This question involves a gene coding for the ability to roll the tongue or not in humans. The allele for tongue rolling (R) is dominant over the allele for non-tongue rolling (r).
According to this question, two individuals that are heterozygous for tongue rolling mate i.e. Rr × Rr. The proportion of offsprings that will be likely produced from this cross will be: RR, Rr, Rr, and rr.
- Offsprings with RR, Rr, Rr are tongue rollers
- Offsprings with 'rr' are non-tongue rollers.
Hence, the predicted genotypic and phenotypic ratio are as follows:
Genotypic ratio = 1 RR :2Rr :1rr
Phenotypic ratio = 3 tongue rollers : 1 non-tongue roller

industrialization, the darker moth population quickly increased since the
tree bark became darker. Which of the following BEST describes why the
