Answer:
The similarity and difference between the nutrition in Amoeba and human beings is as follows:
Explanation:
Nutrition is similar in both humans and amoeba however, there are different nutrition modes in both organisms.
Similarity: Human has complex digestive system while amoeba is a unicellular organism with simple digestion, however, they both use digestive juices. In amoeba, the digestive juices secreted into the food vacuole whereas, the digestive juices are secreted in the stomach and small intestine in humans.
Difference: Amoeba engulfs the food with the help of pseudopodia whereas, humans use the mouth for food intake.
How long does it take the moon to rotate on its axis?
about 25.3 days
about 27.3 days
about 30 days
about 2 months
Answer:
27.3 days
Explanation:
The Moon takes 27.3 days to rotate on its axis as the Moon takes 29.5 days to revolve around the Earth. So, the correct option is B.
What is Rotation?Rotation is defined as the circular movement of an object around a central axis where a two-dimensional rotating object has only one possible central axis and can rotate in a clockwise or counterclockwise direction, while a three-dimensional object has an infinite number of possible centers that is axes and rotational directions.
The Moon orbits the Earth in the same direction, completing one orbit relative to the vernal equinox and the stars in about 27.32 days while one orbit relative to the Sun takes about 29.53 days.
Thus, the Moon takes 27.3 days to rotate on its axis. So, the correct option is B.

Most likely the consequence of this type of mutation is The gene would result in a shorter protein, possibly causing problems. Thus, option "A" is correct.
What is mutation?Mutations are the change in the nucleotide sequence of genetic material due to substitution, deletion or insertion of the nucleotides leading to changed protein.
There are many types of mutations.
If a mutation causes no effect on the protein produced, it is known as the silent mutation. It is usually due to substitution of one nucleotide with the same type of nucleotide as in glycine glycine mutation.
Thus, option "A" is correct.

El vapor se puede transportar a través de la atmosfera. A medida que el vapor se enfría , el agua se condensa en gotitas y forman y forman nubes y da como resultado
Answer:
Precipitación.
Explicación:
El agua se mueve del cuerpo de agua a la atmósfera debido al proceso de evaporación en forma de vapor. A medida que los vapores de agua se enfrían, el agua se condensa en gotitas y forma nubes que resultan en precipitaciones en forma de lluvia y nevadas. Los vapores de agua se vuelven más pesados cuando se condensan y debido a su cuerpo pesado no pueden permanecer en la atmósfera por lo que caen a la tierra en forma de lluvia y nevadas.

In non-muscle cells, a small increase in the cytosolic concentration of Ca2 can have a dramatic effect on several physiological processes. The presence of a specific protein in the cytosol, however, activates a Ca2 ATPase that serves to return these elevated cytosolic Ca2 levels back to basal levels, thereby maintaining the cell's normal physiology. Which protein is directly involved in activating this Ca2 ATPase
Answer:
calmodulin
Explanation:
The calcium-modulated protein (calmodulin) is a calcium-binding receptor protein that modulates contractile proteins (i.e., actin and myosin proteins) of the skeletal muscle and non-muscle cells (e.g., platelets). Calmodulin binds to calcium ions (Ca2+) and subsequently activates a number of Ca2+ dependent enzymes (e.g., kinases or phosphatases), which finally activate/deactivate proteins in the calcium signal transduction pathway. Ca2+-ATPase pumps in the membranes of eukaryotic cells release Ca2+ from the cytoplasm and they are autoinhibited by low Ca2+ levels, while calmodulin-binding releases this autoinhibition and thus activates the pumps. In non-muscle cells such as platelets, calmodulin also mediates Ca2+ control of actin-myosin interaction by phosphorylation of the myosin light chain (MLC).

All members of a population share the characteristic of belonging to the same species. Therefore, the correct option is C.
What is a population?A population is defined as a group of organisms of the same species that live in the same geographic area and are able to interbreed with one another. This means that they share many common traits and characteristics, such as physical appearance, behavior, and genetic makeup.
Option a (temporal isolation) and option b (geographic isolation) are not the characteristics that all members of a population share.
Option d (identical genes) is also not correct, as members of a population may have genetic variation due to mutations, genetic recombination, and other factors. Therefore, the correct option is C.

Without knowing the genetic differences of the birds, how can we know that cardinals and finches are likely more closely related to each other than cardinals and finches are to woodpeckers? Cardinals and finches live in more similar habitats. There is no difference in their relatedness; because they are all birds, they all evolved at the same time from a common ancestor. Cardinals and finches have more morphological similarities. Fossil records show that cardinals have been around longer than woodpeckers and sparrows.
Answer:
The correct answer is - Cardinals and finches have more morphological similarities.
Explanation:
To find out the relatedness of the different species or organisms one can use genetic mapping to find precise relatedness, however, if one can not find the genetic differences of the organism one can use the morphological similarities and differences to find out how closely they are related.
Homologous structures and analogous structures are two major morphological characters to find how closely related cardinals and finches are than cardinals and finches are to woodpeckers.
