One of the effects of the farmer's action on the ecosystem would be that the birds will consume beneficial insects along with the pest species.
Ecological effects of biological pest controlBiological control of pest requires that a living organism that will prey on the pests are introduced into the ecosystem
However, the most effective biological control of pests has to do with introducing biological agents that are very specific in action.
Using a bird species to control insect pests may lead to beneficial insects being consumed along with the insect pest in the ecosystem. The loss of beneficial insects will create a new problem in the ecosystem.

13. What happens when a protein is deNtured?
Denaturation involves the breaking of many of the weak linkages, or bonds (e.g., hydrogen bonds), within a protein molecule that are responsible for the highly ordered structure of the protein in its natural (native) state. Denatured proteins have a looser, more random structure; most are insoluble.

C) hybrid vehicle
D) consumer
E) fuel cell
F) mandated
Answer:
Explanation:
Answer
A fuel cell works on the principal of converting hydrogen and oxygen to electricity. It works on the principle of breaking down the hydrogen into a proton and an electron. When electrons have passed through a passage (having created electricity) they are united with elements in the atmosphere producing heat and electricity and water.
Compare and contrast the left and right hemispheres of the brain, briefly describing their primary functions.
The Split-brain theory describes the differences between left brain and right brain characteristics, functions, and understand the dominance brain.
What is split-brain theory?The split-brain phenomenon is caused by the surgical severing of the corpus callosum, the main route of communication between the cerebral hemispheres. The classical view of this syndrome asserts that conscious unity is abolished
The left brain handles reading, writing, and calculations. Some call it the logical side of the brain whereas The right brain is more visual and deals in images more than words. It processes information in an intuitive and simultaneous manner.
The left hemisphere controls the muscles on the right side of the body while the right hemisphere controls those on the left.

Which gland is responsible for your metabolism? why is this so important?.
Answer:
Thyroid gland
The thyroid gland is an endocrine gland in your neck. It makes two hormones that are secreted into the blood: thyroxine (T4) and triiodothyronine (T3). These hormones are necessary for all the cells in your body to work normally
•It plays a major role in the metabolism, growth and development of the human body.
•It helps to regulate many body functions by constantly releasing a steady amount of thyroid hormones into the bloodstream.
•Its correct functioning depends on a good supply of iodine from the diet.
What is the amount of heat energy needed to raise the temperature of
200 g of water from 10°C to 40°C? (water = 4.18 J/g°C)
Answer:
25116 J
Explanation:
Q = m × c × ΔT
c = 4.186 J/g°C
M=200 g
So,
Q = 200 × 4.186 × (40-10)
=200 × 4.186 × 30
=25116 J
A genius IQ is considered anything over 144. Let's pretend that
this is a genetic condition and that it is recessive. Genius IQ
is found in approximately 1 in 625 people worldwide (this is a
true statistic). Calculate the following:
1. The frequency of the recessive allele (genius IQ).
2. The frequency of the dominant allele (normal).
3. The percentage of heterozygous individuals (carriers).
According to the question, The percentage of heterozygous individuals (carriers). Thus, option "C" is correct.
What is the Hardy-Weinberg equilibrium theory?The Hardy-Weinberg equilibrium theory states that the allelic frequencies in a locus are represented as p and q. Assuming a diallelic gene,
p is the frequency of the dominant allele,
q is the frequency of the recessive allele.
The genotypic frequencies after one generation are
p² (H0m0zyg0us dominant genotypic frequency),
2pq (Heter0zyg0us genotypic frequency),
q² (H0m0zyg0us recessive genotypic frequency)
Thus, option "C" is correct.

if destructive interference occurs between a wave with a six foot trough and a three foot crest, what factors will determine the height of the resulting wave?
Destructive interference formed when the two meeting waves are out of phase and in some cases, the two wavers maxima are 180 degrees out of phase. The height of waves is determined by the wind speed, how the long wind blows, and crucially the fetch.
The longer the duration of wave, the larger will be the wave heights. The longer the fetch, the large will be wave heights.
What is interference?Some waves jump to cross over or meet with each other. When they do, the reaction between the waves is called interference.
If at a given location, both interfering waves are supersede in the same direction (both up or both down) then it is known as constructive interference.
