Answer:
OH LOL I DID THIS IN 7TH GRADE
Explanation:
so if i remember when the trees where white the pepper moths that where white survived more often that the black ones, then when the industrial war came the trees where covered in ash, so the white moths survived
MY SENTENCE
It shows how a change in an environment can effect a species natural selection, for example the white moths survived more than the black moths so the reproduced while the black moths where eaten by predator's, then when the environment changed and favored the black moths they survived and reproduced while the white moth got picked off by predators.
Hope this helped mate :>

2. Beyonce has a straight hairline, which is a recessive trait. Bruno also has a straight hairline. What is the chance that their child would have a widow’s peak? _____
3. Beyonce has no dimples (Dd). Bruno has dimples, which is a recessive trait. What is the chance that their child would have dimples? _____
4. Beyonce has a cleft chin (CC). Bruno has a smooth chin, which is a recessive trait. What is the chance that their offspring would have a smooth chin? ____
5. Beyonce and Bruno are both heterozygous for brown eyes. What is the genotypic ratio for their offspring?
Answer:
100%
100%
50%
100%
75%
Explanation:
dont use the exact words so u can avoid plagerism lol
Complete dominance occurs when the dominant allele completely masks the recessive allele in heter0zyg0us individuals. 1) 100% / 2) no chance / 3) 50% / 4) no chance / 5) 1:2:1.
------------------------------------------------------------
Available data:
→ Six diallelic genes code for six different traits.
→ All genes express complete dominance, meaning that the dominant allele hides the expression of the recessive one.
→ Beyonce ⇒ ee ww Dd Hh cc Bb
→ Bruno Mars ⇒ ee ww dd Hh CC Bb
→ Cross: Beyonce x Bruno Mars

Read the excerpt from the introduction for "On Becoming an Inventor" by Dean Kamen.
I had just finished making a complicated piece of equipment that was to be used for a show opening in Philadelphia called "Fiorello." When the machine arrived they had trouble wiring it, so instead of going off to college that morning for an orientation, I spent several days at the theater fixing my light/sound equipment. The show received poor reviews, except for the mention by one reviewer of the "special effects," which, he wrote, were "outstanding."
Which detail from the excerpt proves that Dean created very good light/sound equipment?
He made a piece of equipment for a show named "Fiorello."
The show's crew had trouble wiring the equipment.
Dean spent several days at the theater fixing the equipment.
The equipment got great reviews, even though the show did not.

Acetylcholine is found in the synapse between muscles cells and neurons. It can be broken down by the enzyme acetylcholinesterase. Which of the following describes what happens if acetylcholinesterase is inhibited?
Acetylcholine will continue to be activated.
Acetylcholine will be prematurely terminated.
Acetylcholine will lose specificity of the response.
Acetylcholine will be inhibited.
Answer:
Acetylcholine will continue to be activated.
Explanation:
When we inhibit acetylcholinesterase with an acetylcholinesterase inhibitor (AChEI) it will inhibit acetylcholinesterase from breaking down acetylcholine into choline and acetate. This will increase the level and the duration of the neurotransmitter in the CNS, autonomic ganglia, and neuromuscular junctions.

Which three minerals are most commonly found in the igneous rock granite?
Answer:
Granites and rhyolites consist predominantly of quartz and potash feldspar; gabbros and basalts, predominantly of pyroxene and plagioclase feldspar. Other rock types have intermediate mineral compositions.
Explanation:
It is made up of sodium feldspar, potassium feldspar, and coarse quartz grains (10–50%). More than 80% of the rock is composed of these minerals.
What is igneous rock granite?Granite is a pale-colored plutonic rock that is mostly found in mountainous regions of the continental crust.
Quartz and potash feldspar make up the majority of granites and rhyolites, whereas pyroxene and plagioclase feldspar make up the majority of gabbros and basalts. Other types of rocks contain mineral compositions that are in between.
Magma, which is a molten substance that flows and hardens underground while slowly cooling, is the source of intrusive rocks.
Therefore, the majority of the continental crust is composed of granite, the most common kind of igneous rock, intrusive igneous rock is granite.

As part of a laboratory experiment in his psychology course, Miguel is observing the activity of a recording electrode on the axon of a neuron. As an action potential
occurs what might Miguel observe?
A The axon will release neurotransmitters into the synapse.
B. The avon will remain at threshold potential as negative ions continue to flood the cell.
OC The decial charge of the neuron will go from positive to negative before returning to threshold potential.
OD. The curical charge of the neuron will go from negative to positive before returning to resting potential
Answer:
The correct answer is D
Explanation:
A resting neuron has a voltage across its membrane, which is referred to as resting potential. This resting potential is caused by concentration gradients of ions across the membrane. A neuron returns to the threshold potential by the movement of positive ions (especially K+ ions) through channels that stay open to exit the neuron.
Which of the following best describes the relationship between the endoplasmic reticulum and the plasma membrane in eukaryotic cells?
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, there is a distinct relationship between the endoplasmic reticulum and the plasma membrane. The endoplasmic reticulum are responsible for protein synthesis which are used by the remaining organelles (including the membrane) to function. The endoplasmic reticulum is also involved in lipid synthesis and has a network of tubules (which are used for carrying materials throughout the cell) that can deliver lipids into the cell membrane. These lipids are responsible for the semi-permeability function of the cell/plasma membrane.
what is the difference between autosomes and gametes
Answer:
An autosome is any of the chromosomes, except the sex chromosomes, while is the sex cell.
Explanation:
Humans have 22 pairs of autosomes and one pair of sex chromosomes (pair number 23, made up of two X chromosomes in women and one X and one Y chromosome in men). Autosomes are numbered according to their relative size.
Gametes are the sex cells of multicellular and human organisms. They are haploid cells (that is, they contain 23 chromosomes, n), they originate by meiosis from germ cells (they contain 46 chromosomes, 2n).
During this process, germ cells mature and change shape until they become future gametes or cells with fertilizing capacity.

Please hurry! What is our body’s hidden strength?
Answer: One major clue is that we humans are, quite simply, stronger than we realise. Our movements are controlled by the contraction of muscles through signals relayed by nerves. When going about our daily lives, our bodies tend to use whatever the least amount is of muscle-and-nerve "motor units" to perform an action.

Answer: A community
Explanation: Abiotic is not living, all the things mentioned are alive so this is not correct.
A population is a number of organisms of the same species living together in an area at the same time.
A community is an interacting group of various species in a common location. The common location here is a pond.

he cell cycle is essential for ensuring that our cells don't grow too large. Explain why it is necessary for cells to remain small in size.
Answer:
it is necessary for cells to remain small in size because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients and exchanging materials between the inside and outside of cells.
Cells are small so they can have an efficient surface area to volume ratio. This is going to allow the cell to easily excrete waste product.
That is why the cell needs to be small. The smaller it is, the larger the surface area to volume ratio is.
