The graph shows levels of carbon dioxide (CO2) in Earth's atmosphere over the last 400,000 years.

Based on the data in the graph, what can be said about current carbon
dioxide levels?

A. They are at the high point of a natural, repeating cycle.
B. They are no different from levels in the past.
C. They are far higher than the highest natural levels.
D. They are much lower than normal.

Answer: B. white-eyed female

Explanation: Took biology

Answer:

B. White eyed female

Explanation:

The genotype consist of two recessive alleles (rr). When there are two recessive alleles the phenotype will be the recessive trait which in this case is white eyes

Answer:

Krebs cycle

Explanation:

The Krebs cycle is a set of chemical events that all aerobic organisms employ to generate energy by converting acetate (which comes from carbs, lipids, and proteins) to carbon dioxide. There are various alternatives to the TCA cycle in theory, but it appears that the TCA cycle is the most efficient.

Answer: Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria. ... In heart muscle cells about 40% of the cytoplasmic space is taken up by mitochondria.

Explanation:

The process is called oxidative phosphorylation and it happens inside mitochondria. In the matrix of mitochondria the reactions known as the citric acid or Krebs cycle produce a chemical called NADH. NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP).

(c) applies only when both alleles are recessive.

Have you had a drastic changes in belief or a small one before?

Answer:

I used to think that seasons were caused by Earth getting closer to and farther from the Sun. My science teacher pointed out that when it’s summer in North America, it’s winter in the Southern Hemisphere. So, I realized that seasons are not caused by Earth’s closeness to the Sun.

There was more erosion in the Colorado Rockies scenario where there was steady rain compared to the scenario in the same area where there was only a drizzle. There is more erosion because the steady rain increased the volume of the river more than the drizzle did.

The correct answer is D. An unmanaged resource that is limitless.

Explanation

Sustainable resources are those natural resources that can be used today without compromising the resources and possibilities of future generations. Sustainable resources are characterized for being limitless and not being produced by humans, that is,  generated by nature, for example, solar energy, wind energy, hydraulic energy (from water), among others. Unlike non-renewable resources are those that have a limit, such as water, oil, natural gas, among others. Therefore, the correct answer is D. An unmanaged resource that is limitless.

Answer:

Directional selection

Explanation:

When a population experiences a shift in diversity toward the larger organisms, it is directional selection.

The term directional selection has to do with a type of selection in which the specie tend towards one side of the population mean.

Therefore, when a population experiences a shift in diversity toward the larger organisms, it is directional selection.

Answer: The three mentioned substances (nucleotide, amino acid and glucose) are the BASIC UNITS of its various biological macromolecules.

Explanation:

NUCLEOTIDE is defined as the BASIC UNIT or the building block of nucleic acid such as Deoxyribonucleic (DNA) and Ribonucleic (RNA). It contains a sugar molecule, a phosphate group and a nitrogen containing base. They have a variety of functions which include:

--> they are the building blocks of substance that control hereditary characteristics.

--> energy carriers,

--> components of enzyme cofactors, and

--> chemical messengers.

AMINO ACID: This is defined as the BASIC UNIT that makes up the biological macromolecule known as PROTEIN which helps in the growth and repair of worn out tissues of the body.

It is made up of basic amino group, an acidic carboxyl group, and a unique organic side chain.

GLUCOSE: This is also the BASIC UNIT of the biological macromolecule called carbohydrates. They are also called simple sugars which are the body's preferred source of energy in the form of carbohydrates.

B

Explanation:

Plants use photosynthesis from chloroplasts to make food

Answer:

Fenotipo: Moscas negras y moscas blancas.

Genotipo: Nn y nn.

Explanation:

Sabemos que al cruzar dos moscas un pequeño porcentaje de su descendencia es blanca y la mayoría negra. Por ende, hay dos alelos distintos para el color, uno codifica para moscas de color negro y el otro para las de color blanco. Como la mayoría de la descendencia es negra, el gen domiante es el negro, a este lo denominaremos con la N y al recesivo con la letra n.

Para que haya moscas blancas, las dos moscas que se cruzan tienen que ser Nn, es decir, su genotipo tiene que ser heterocigoto. Podemos verificar esto con un cuadro de Punnett:

  ║N  ║n

N║NN║Nn

n║Nn ║nn

Con el cuadro de Punnet vemos que la descendencia tiene los genotipo, es decir, los genes que un ser tiene, Nn y nn. El fenotipo, es decir, lo que podemos ver de los genes, sera moscas de color negro y moscas de color blanco.

Como el gen dominante es el negro, cualquier mosca con este gen expresara este color y solo las moscas con genotipo h0m0cigoto (nn) expresaran el color blanco.
