What is true about DNA mutations?
Answer:
B
Explanation:
Crossing over is the process involved during meiosis of two chromosomes sharing genetic information with each other from each parent. This happens so the two daughter cells or sister chromatids have a variety of genetic information and so they are not completely identical. This leads to genetic diversity or variation.

Actually, Sherman, there are more black moths than white ones because . . .
Answer:
The dark moths camouflage with the dark bark of the tree so that they can stay hidden from predators and eat their food safely. The white moths do not blend in with the bark and are more likely to be found by predators.

Red-green color-blindness is an X-linked recessive condition. Juliet has a bit of difficulty passing the red-green color distinction test when she tries to get her driver's license. She has two children with a man who is not color blind. Neither Juliet's son (Henry) nor daughter (Roxanne) is color blind. Henry and Roxanne have normal karyotypes. Roxanne has a son who is color blind.
Required:
a. What is Juliet's genotype for the color-blindness allele? How would you explain her partial color blindness?
b. Why aren't Henry and Roxanne color blind?

Due to technical problems, you will find the complete answer and explanation in the attached files.
What is lectin pathway
Answer:
The lectin pathway or lectin complement pathway is a type of cascade reaction in the complement system, similar in structure to the classical complement pathway, in that, after activation, it proceeds through the action of C4 and C2 to produce activated complement proteins further down the cascade.
A material was cooled from 100ºC to 40ºC. What is the temperature change?The specific heat of water is 4.18J/goC. I need the full explanation would mean a lot to me.
Answer:
-60°C
Explanation:
According to this question, a material was cooled from 100ºC to 40ºC.
The temperature change, which is symbolized by ∆T = final temperature - initial temperature
That is, ∆T = T2 - T1
In this question, T2 = 40°C, T1 = 100°C
Hence, ∆T = 40°C - 100°C
∆T = -60°C

The greatest delivery of oxygen from the blood to the surrounding tissues occurs at 37C. Colder blood temperature results in greater dissociation of oxygen and hemoglobin. Hemoglobin has a lower affinity for oxygen under high temperature conditions. Increasing blood pH results in more oxygen unloading in tissues.
Answer:
Option 3 (Hemoglobin.................conditions) is the correct statement.
Explanation:
In the given question, the graph seems to be missing. Please find the attachment of the graph below.
Everything just produces the main controller throughout the curve all through hyperphrenic disease, this implies the hemoglobin compatibility for oxygenation is affected by the heat intensity. When warming reduces sensitivity, the appreciation rises when the temperature lowers or drops.There are other choices not associated with the condition. Thus, the response is the correct one.
The graph shows data from ice cores. What has happened to carbon dioxide levels over time?
A. They have increased dramatically recently.
B. They have remained flat and steady.
C. They have decreased dramatically recently.
D. They have gone up and down with no general trend.
Answer:
A they have increased dramatically
Explanation:
As the time progresses it was relatively stable until about 1800, and then the atmospheric CO2 increased dramatically
A student designed an experiment to demonstrate the interaction between Earth systems. The steps of the experiment are given below.
Fill three-fourths of a glass jar with water.
Add a teaspoon of liquid dish soap and a teaspoon of vinegar to water.
Tighten the lid and shake the jar to mix the ingredients.
Swirl the jar in a circular motion and watch the spinning motion of the liquid inside.
The student’s experiment demonstrates the formation of
A- blizzard due to the interactions between the hydrosphere and geosphere
B- hurricanes due to the interactions between the geosphere and atmosphere
C- tornadoes due to the interactions between the hydrosphere and atmosphere
D- thunderstorms due to the interactions between the hydrosphere and cryosphere
Answer:
Its C
Explanation:
-Ella-
The experiment performed by student only creates the vortex, caused by the interaction between the liquid and its movement in the jar. Therefore, none of the statements are true.
What is vortex?The experiment performed by student involves mixing water, dish soap, and vinegar in a jar, thereby, creating a solution having a lower surface tension than plain water. Due to swirling of the jar, the liquid inside the jar spins creates a difference in surface tension between the center and the edges of the jar.
This effect is known as the vortex, caused by the interaction between the liquid and its movement in the jar.
The experiment by the student does not demonstrate the interaction between Earth systems. Blizzards and hurricanes occur due to interaction between the atmosphere and the Earth's surface, while tornadoes and thunderstorms occur due to atmospheric convection currents.
Therefore, only vortex is caused by the interaction between the liquid and its movement in the jar.

A stable ecosystem is characterized by having A)predators that outnumber their preyB)a continual input of energyC)limited autotrophic nutritionD)no competition between species
Answer:
B) a continual input of energy.
Explanation:
An ecosystem can be defined as the natural living habitats of both living and non-living organisms, in which they interact with one another. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.
An ecosystem is generally considered to be stable if it's capable of applying self-regulating mechanisms in order to return to an equilibrium state, after an experiencing an outside disturbance or perturbation. Thus, a stable ecosystem maintains a natural balance of nutrients and energy.
In an ecosystem, producers are the living organisms that are capable of manufacturing their own food and as such can provide energy or food for the other living organisms (consumers) in a food chain. Thus, producers are mainly known as the foundation of a food chain and are at the top.
Generally, a producer gets energy from the sun and converts it into food. The cells found in producers are capable of converting the energy received directly from the sun into food through a process generally referred to as photosynthesis, converting carbon dioxide from the air, water from the soil, minerals and energy from the sun into organic nutrients.
Hence, a stable ecosystem is characterized by having a continual input of energy.
What does delegation involve?

Which one is more biologically disruptive a point mutation or a frameshift mutation
Answer:
Frameshift
Explanation:
A point mutation can be insignificant due to the genetic code, many amino acids come from similar codons (where one base can be incorrect and it results in the same amino acid). If it does change the amino acid, having only one different amino acid in a whole polypeptide chain usually does not cause a major problem.
However, a change in the reading frame can be a major issue because it changes every codon form what it should be. A frame shift mutation can even prevent the translation of a protein entirely if it effects the start or stop codon.
Terribly articulated, but the answer is 100% frameshift

Answer:
The correct answer is - upward, two.
Explanation:
The bitewing radiograph (BW) is a radiography image that is used to see the crowns of the maxillary and mandibular teeth, the interproximal surfaces of the teeth, and identifying interproximal caries.
The curve of the spee is also can be seen and mount with this image the curve of the spee is start at the tip of the lower canine, rn with the buccal cusp tips of the premolars and molars and continuing to the anterior end of the ramus. it is 2-D and upward from distal. It also shows that mandibular molar teeth have two distinct roots.
