Autotroph. Autotrophs include plants and some other creatures, vacuoles and chloroplasts are found in plants.
Explanation:
PLANTS! = Autotroph. I don´t even know anymore, it´s been 3 years since I took a basic science class, I am guessing from memory.
The hemoglobin protein of a human and a frog differ by 67 amino acids. How many amino acids are most likely different between a human and a chimp?
A. none
B. fewer than 67
C. 67
D. more than 67
Answer:
B. Fewer than 67
Explanation:
Humans are much more closely related to chimps than frogs, so the genetic information that codes for their proteins will differ much less.
Based on the evolutionary relationship between humans and chimpanzees, it is highly likely that humans and chimpanzees share a large portion of their genetic material, including the amino acid sequence of hemoglobin. Therefore, it is most likely that the answer is B. Fewer than 67 amino acids are different between a human and a chimp.
What is the hemoglobin of different animals?The hemoglobin protein is a vital protein in both humans and chimpanzees that helps transport oxygen in the blood. While there may be some variations in the amino acid sequence of hemoglobin between humans and chimpanzees, it is expected that most of the amino acids will be the same since hemoglobin performs a critical function in both species. Additionally, any differences in the amino acid sequence of hemoglobin between humans and chimpanzees are likely to be fewer than 67, as this is the number of differences between humans and frogs, which are much more distantly related species.
Hence, it is most likely that the answer is B. Fewer than 67 amino acids are different between a human and a chimp.

What type of transport was shown in the second animation?
A. active transport with the help of transport proteins
B. passive transport by simple diffusion across the membrane
C. passive transport by facilitated diffusion with the help of transport proteins
Answer:
C. passive transport by facilitated diffusion with the help of transport proteins
Explanation:
The electron transport chain (shown in the second animation) establishes a proton gradient across the inner mitochondrial membrane. ATP synthase uses the energy stored in the proton gradient to catalyze the synthesis of ATP. The molecular machinery involved in this process converts chemical energy to mechanical energy and provides a great example of the relationship between the structure and function of macromolecules.
Answer:
C. passive by facilitated diffusion with the help of transport proteins
Explanation:
Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes.

Distinguish between gaseous exchange and respiration
Answer:
Respiration is the process in which food is oxidized to release energy. Complex organic compounds are converted into simpler ones, e.g glucose into CO2 water and energy released. Gaseous exchange is the diffusion of gases from a region of higher concentration to a region of lower one.
Explanation:
Breathing is the physical process by which air is passed on a gaseous exchange surface i.e. ventilation of the gaseous exchange surface. It involves Inhalation and Exhalation.
Gas/Gaseous exchange is the process whereby gasses diffuse across a gaseous exchange surface. In humans, oxygen diffuses from the inhaled air into the blood and carbon dioxide diffuses from the blood into the exhaled air. The gaseous exchange surface here being the Alveoli.
Respiration is the metabolic process whereby organic molecules are broken down to release energy in the cells. In humans, this process takes place inside the mitochondria of cells. Aerobic respiration requires oxygen whereas qnqerobic respiration takes place in absence of oxygen.

Explain your justification for the changes in trait distribution between years 1 and 10. What do you think will happen to the population by year 15?
Answer:
It will continue to rise.
Explanation:
Genetic variation results in the changes in trait over the period of time. Hence, traits do change over the years, but it is a gradual process. The population will become more stable due to successful traits.
What is genetic variation?Genetic variation refers to the changes in the genotype of an individual. It imparts stability to the population. Genetic variation results from meiotic cell division where recombination of gene produces genetic exchange of heredity material.
Those traits which are successful in nature that means those variations which provide stability to the organism in any environment are favoured. Organisms with such variations adapt, survive and further reproduce to continue their existence. Such traits are transmitted to the progeny as well.
Thus, gradual accumulation of changes in traits contribute to a more stable population over the span of years.
Therefore, changes in traits are important in determining the track of evolution on earth.

Al cruzar 2 moscas negras se obtiene una descendencia formada por 216 moscas negras y 72 oscuras blancas. A) Razone el cruzamiento y determine fenotipo y genotipo.
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.
