Explanation:
A student is presented with a model of a digestive system and is asked to remove one structure (small or large organ) that will have the largest impact on decreasing chemical digestion. Which structure should the student remove
Answer:
Small intestine
Explanation:
Digestion is the process of breaking down food molecules into simpler and usable forms by the body cells. The process of digestion involved the mechanical aspect and chemical aspect. The mechanical one deals with using physical means like chewing to break down the food particles.
However, the chemical one deals with the usage of chemically-secreted enzymes to work on the food molecules. Lots of digestive organs are involved in this chemical digestion, but, the most of chemical digestion takes place in the SMALL INTESTINE. The small intestine is where most of the chemical digestion occurs including absorption.
Hence, according to this question, the student should remove the SMALL INTESTINE because it will have the largest impact on decreasing chemical digestion.
What products of the Calvin Cycle are used by the light reactions?
Answer:
ATP and NADPH
Explanation:
The Calvin cycle uses the reducing powers ATP and NADPH from the light dependent reactions to produce sugars for the plant to use.
Two genes are hypothesized to be linked. The map distance between the genes is thought to be 12 map units. Out of 1000 offspring produced by two heterozygous parents, predict how many would occur in each phenotypic category.
Answer:
Approximately the number of individuals with each phenotype is:
RS-->0.75 x 1000 = 750rs--> 0.19 x 1000 = 190Rs--> 0.05 x 1000 = 50rS--> 0.05 x 1000 = 50Explanation:
Available data:
Two genes are hypothesized to be linkedThe map distance between the genes is thought to be 12 map units. Two heterozygous parents1000 offspring producedLet us say that the two diallelic genes are R (alleles R and r) and S (alleles S and s)
Heterozygous parents might have the following genotype RS / rs
We know that there are 12mp between genes, which means that the recombination frequency equals 0.12 or 12%.
0.12 of the gametes are recombinants and 0.88 are parentals. There are two types of parentals and two types of recombinant, so 0.06 + 0.06 are recombinants while 0.44 + 0.44 are parentals. This is:
Cross:
Parentals) RS/rs x RS/rs
Gametes) RS (parental) 0.44
rs (parental) 0.44
Rs (Recombinant) 0.06
rS (Recombinant) 0.06

F1) Genotypes:
1 RS/RS --> 0.44x 0.44 = 0.1936 2 RS/rs --> 0.44x 0.44 = 0.1936 x2 = 0.38722 RS/Rs --> 0.44 x 0.06 = 0.264 x 2 = 0.0532 RS/rS --> 0.44 x 0.06 = 0.264 x 2 = 0.0531 rs/rs --> 0.44x 0.44 = 0.1936 2 rs/Rs --> 0.44 x 0.06 = 0.264 x 2 = 0.0532 rS/rs --> 0.44 x 0.06 = 0.264 x 2 = 0.0531 rS/rS --> 0.06 x 0.06 = 0.00361 Rs/Rs --> 0.06 x 0.06 = 0.00362 Rs/rS --> 0.06 x 0.06 = 0.0036 x 2 = 0.0072Phenotypes:

a)Both have elongated centers.
b)Both have shapes determined by gravitational forces.
c)Both change their shape from time to time.
d)Both are held together by electrostatic force.
Answer:
I think its B
Explanation:
Because all I know is that galaxies are defined as the system which contains billions of stars bind together by gas or dust and held together by gravitational forces. There are also three types of galaxies which are elliptical, spiral, and irregular shaped and all galaxies have different shapes of centers.
Answer:
Both change their shape from time to time.

The statement "Cognition is studied indirectly" is true.
What is cognition?The mental action or process of obtaining psychological features and apprehension through self-satisfaction, experience, and the senses is the definition of cognition.
Cognitive psychologists are interested in the investigation of mental functions. This relates to the study of cognition, memory, learning, and problem-solving processes in people. Cognitive psychologists are interested in how people think or react psychologically to various situations.
On the other side, behavioral psychologists are interested in researching and observing behavior. It is additional research on the interactions between stimulants and outcomes.

Explanation:
Predict one possible problem with a DNA molecules' structure that could occur.
Answer: DNA damage due to environmental factors
Explanation:
DNA is a genetic material present in the cell of living organisms. The DNA can be damaged by the environmental factors which can induce mutations in the structure of the DNA further affecting the function. The environmental factors like ultraviolet rays, chemicals, ionizing radiation can damage the structure of the DNA. For example, the chemical may contain alkylating agents which can cause the hydrolysis of the chemical bonds in the DNA.

1. What are the differences and similarities between an asteroids and comets?
or
2.What are the differences and similarities between the moon and a planet?
Answer:
Asteroids or planetoids are small solids in planetary systems. They usually orbit the parent star in their own orbit or as natural satellites (moons) of larger planets.
A comet is a celestial body that is in an elliptical orbit around the Sun. They come from the farthest and coldest areas of the solar system.
Explanation:
The moon is the only natural satellite of the Earth and at the same time the closest celestial body.
It is the brightest celestial body in the night sky, not because it consists of incandescent gases like the sun, but because it reflects sunlight.
A planet is a celestial body that moves directly in an elliptical orbit around a star, not like a natural satellite, which orbits a star while circling around another body.

What are some methods that predators use to capture prey?
Answer:
Offensive Strategies of Predators
Cheetahs use speed to outrun their prey, and eagles, hawks, owls and falcons use flight to their advantage while hunting. Venomous snakes, spiders and wasps use poisons to either kill or immobilize their prey. Some predators even use mimicry to capture prey.
The Lubber grasshopper is a very large grasshopper, and is black in color with stripes. The color of the stripes exhibit incomplete dominance. Red stripes or yellow stripes may be expressed; however, when alleles are mixed, orange stripes are expressed. What will be the genotypic and phenotypic ratios be for the offspring of two parents that both have orange stripes.
Genotype: ______________________________
Phenotype: _____________________________
Explanation:
Let R be the allele for red stripes.
Let r be the allele for yellow stripes.
Parental phenotypes:
Orange stripes * Orange stripes
Parental genotypes:
Rr * Rr
Gametes:
(R)(r) * (R)(r)
Using a Punnett's Square, we get
F1 generation genotypes:
RR : Rr : rr = 1 : 2 : 1
F1 generation phenotypes:

"Image result for why cells can form tumors
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor."
