Answer:
The answer will be listed below.
Explanation:
Autotroph and heterotroph are two different terms. Autotrophs are producers, such as plants and other organisms that can produce their own food. Heterotrophs are consumers who consumes producers or other consumers to get their food. Examples include animals, people, and those who consume other things for energy.
How many neutrons are in a nucleus of an atom that
has an atomic mass of 16 and an atomic number of
Answer:
4
Explanation:
Page 1 Page 2 Radioactive decay involves the changing of a radioactive atom into another radioactive atom. For example, rocks and minerals may contain potassium-40 that changes into argon-40. Mass spectrometers measure the number of these atoms in a rock or mineral sample. This information and knowing the half-life of potassium-40 can help determine the age of rock layers. The half-life of potassium-40 is 1.3 billion years. The potassium-40 in rocks and minerals will decay through many half-lives until all of them change into argon-40. How many atoms will there most likely be at the third half-life of potassium-40 in this model? A model rock layer had 50 pennies (atoms of potassium-40). How old is the rock layer?

B. Water is nonpolar and oil is nonpolar therefore the substances won't mix.
C. Water is nonpolar and oil is polar therefore the substances will not mix.
D. Water is polar and oil is nonpolar therefore the substances will not mix.
Answer:
Water is polar and oil is nonpolar so the substances won't mix.
Explanation:
Water is polar covalently bonded within the molecule. This unequal sharing of the electrons results in a slightly positive and a slightly negative side of the molecule. oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water.

Where in the cell does the krebs cycle part of cellular respiration occur ?
Answer:
In the mitochondrial matrix
Explanation:
The mitochondria is an organelle within the cytoplasm of the cell. It consists of an outer membrane, inner membrane, and matrix containing a gel-like substance. During aerobic respiration in mitochondria, cells break down sugars in the form of glucose into [tex]CO_{2}[/tex] (carbon dioxide) and [tex]H_{2} O[/tex] (water) to obtain energy in the form of ATP or adenosine triphosphate.
aerobic respiration:
C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
(glucose) (oxygen) (carbon dioxide) + (water)
The Kreb's cycle involves several enzymatic reactions, where pyruvate derivatives obtained from glycolysis, are reduced and oxidized to harvest energy as ATP.

The following four ears of corn were taken from separate plants. Each kernel represents an offspring. The kernels on the four ears were counted for the color trait (purple or white) and/or sweetness trait (starchy or sweet). The data gave these phenotypic ratios for the four ears:
Ear #1 – 3 purple : 1 white
Ear #2 – 3 starchy : 1 sweet
Ear #3 – 9 purple, starchy : 3 purple, sweet : 3 white, starchy : 1 white, sweet
Ear #4 – 1 purple : 1 white
Which traits are recessive?
Answer:
the answer is white and sweet, i just took the quiz
Explanation:
The phenotypic ratio provides information about how many genes are involved in the cross, which is the dominant trait and which is the recessive trait. In the exposed example, white and sweet are the recessive traits.
-------------------------------
By looking at the phenotypic ratio of the progeny, you can tell which trait is the dominant one and which is recessive.
Let us assume two diallelic genes, each coding for one trait.
Let us also say that these genes assort independently -they are not linked-, and they do not interact with each other.
When we are only considering one single gene,
the phenotypic ratio after crossing two heter0zyg0us individuals is 3:1. In these situations, we expect to see 3/4 of individuals expressing the dominant trait, and 1/4 expressing the recessive trait.the phenotypic ratio after crossing a heter0zyg0us individual with an h0m0zyg0us recessive one is 1:1. We expect to see 2/4 of the progeny expressing the dominant trait and 2/4 the recessive trait.When we are only considering two genes simultaneously, we expect to find the following phenotypic ratio 9:3:3:1
9/16 individuals expressing both dominant traits3/16 individuals expressing one dominant trait and one recessive trait1/16 individuals expressing both recessive traits.
Now let us analyze each Ear,
Ear #1 – 3 purple : 1 white
Only the color trait is considered. The phenotypic ratio is 3:1Two heter0zyg0us individuals must be involved in the cross3/4 are purple and 1/4 is whiteDominant trait: purpleRecessive trait: white
Ear #2 – 3 starchy : 1 sweet
Only the sweetness trait is considered. The phenotypic ratio is 3:1Two heter0zyg0us individuals must be involved in the cross3/4 are starchy and 1/4 is sweetDominant trait: starchyRecessive trait: sweetEar #3 – 9 purple, starchy : 3 purple, sweet : 3 white, starchy : 1 white, sweet
Both traits are considered. The phenotypic ratio is 9:3:3:1Two dihybrid individuals must be involved in the cross9/16 are purple and starchy, 3/16 are purple and sweet, 3/16 are white and starchy, and 1/16 is white and sweetDominant trait: purple and starchyRecessive trait: white and sweetEar #4 – 1 purple : 1 white
Only the color trait is considered. The phenotypic ratio is 1:1One heter0zyg0us individual and one h0m0zygous recessive individual must be involved in the cross2/4 are purple and 2/4 are whiteDominant trait: PurpleRecessive trait: WhiteThe recessive traits are white color and sweet taste.

How Is the Earth Changing? How would you answer this question now?
Answer: Climate change
Answer:
Humans—more specifically, the greenhouse gas (GHG) emissions we generate—are the leading cause of the earth's rapidly changing climate. Greenhouse gases play an important role in keeping the planet warm enough to inhabit. But the amount of these gases in our atmosphere has skyrocketed in recent decades. Global sea level rise is complex as well. To begin with, it has multiple causes, including the thermal expansion of the ocean as it warms, runoff of melt water from land-based ice sheets and mountain glaciers, and changes in water that’s stored on land. These factors combine to raise the height of our global ocean about 3.3 millimeters (0.13 inches) every year. That rate is accelerating by another 1 millimeter per year (0.04 inches per year) every decade or so.

Explanation:
Answer: There are three stages
Explanation: Cellular respiration occurs in the cells of all living things, both autotrophs and heterotrophs. All of them burn glucose to form ATP. The reactions of cellular respiration can be grouped into three stages: glycolysis, the Krebs cycle (also called the citric acid cycle), and electron transport.
question one: why do stars change very little while they are in the main sequence stage?
question two: why does a main sequence star eventually grows in size to become a red giant?
Answer:
Q1 As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts.
Q2When stars first begin to fuse hydrogen to helium, they lie on the zero-age main sequence. ... The core of a red giant is contracting, but the outer layers are expanding as a result of hydrogen fusion in a shell outside the core. The star gets larger, redder, and more luminous as it expands and cools.
Explain the relationship between the processes of breathing and cellular respiration
Cellular respiration uses oxygen to release the energy stored in food.
Explanation:
In breathing living organisms take oxygen and release the carbon dioxide it is similar to the aerobic respiration.
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide!

How are influenza viruses classified?
by their type of movement
by their protein structure
by their genetic material
by their different shapes
Answer: They are classified by subtypes based on the properties of their hemagglutinin (H) and neuraminidase (N) surface proteins. There are 18 different HA subtypes and 11 different NA subtypes. Subtypes are named by combining the H and N numbers.
1.There movement: People with flu can spread it to others up to about 6 feet away. Most experts think that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
2. There protein structure: The influenza viruses are classified into types A, B, and C on the basis of their core proteins. Type A viruses are further subdivided according to their envelope glycoproteins with haemagglutinin (HA) or neuraminidase (NA) activity.
3. There genetic material: by subtypes based on the properties of their hemagglutinin (H) and neuraminidase (N) surface proteins. There are 18 different HA subtypes and 11 different NA subtypes. Subtypes are named by combining the H and N numbers – e.g., A(H1N1), A(H3N2)

Explanation:
Un organismo con un caracter genotípico heterocigote presentará, excepto A Alelos iguales B una linea híbrida C alelos diferentes D una linea pura E a y d
Answer:
C alelos diferentes.
Explanation:
Los alelos son las distintas formas en las que un gen puede ser expresado. Cuando un gen es dialélico implica que puede haber dos formas diferentes del mismo gen, una dominante y otra recesiva. Estos alelos serán heredados de la línea parental en la que un progenitor aporta un alelo y el otro progenitor aporta otro alelo, que se combinaran durante la formación del cigoto. La combinación de alelos de un mismo gen en un organismo determina la forma en la que determinada característica será expresada en el individuo.
• Cuando dos alelos iguales se combinan en un organismo, se habla de un genotipo homocigota. Estos alelos pueden ser los dos dominantes o los dos recesivos.
• Cuando se combina un alelo dominante con uno recesivo, se habla de genotipos heterocigotos. El individuo que posea un genotipo heterocigota, portará ambos alelos pero expresará el fenotipo del alelo dominante.
