A human needs about 2500 calories of energy per day. You could supply this energy (ignoring nutritional sanity) by eating 600 grams of starch, digesting it to glucose, absorbing it, and then respiring it. To respire 600 grams of starch, you need about one gram of oxygen for every gram of starch digested to glucose. If you average 10 breaths a minute for 24 hours, how many grams of oxygen do your lungs need to transfer to your blood with each breath

The study of human biology within the framework of human evolution can be said to be the domain of physical/biological anthropology (B)
Physical and biological anthropology is the study of the evolution of the human species both in the past and in the present, with a primary focus on determining the factors that led to the wide range of human variation that exists today. Biological anthropology, which is also known as physical anthropology, is one of the classic subfields that fall under the umbrella of the discipline of anthropology. Along with cultural anthropology, archaeology, and linguistic anthropology, it is a component of the multidimensional core of what anthropology is in the United States.

Answers
b. She draws branches for gymnosperms at the beginning of her tree.
c. She draws branches for simple land plants after the branches for flowering plants.
f. She draws a branch for gymnosperms after the branches for vascular plants.
What is the Gretta's organization of her phylogenetic tree?Gretta's organization of her phylogenetic tree likely follows the current understanding of plant evolution. Gymnosperms are considered to be one of the earliest groups of plants to evolve and are therefore placed at the beginning of the tree.
Flowering plants, also known as angiosperms, are a more recent group of plants that evolved after gymnosperms and are placed after gymnosperms in the tree. Simple land plants, which include nonvascular plants, are thought to have evolved before vascular plants, and are therefore placed after flowering plants. Vascular plants, which include both gymnosperms and angiosperms, are a diverse group of plants that evolved a system of tubes for transporting water and nutrients throughout the plant. Gymnosperms and angiosperms are placed in separate branches of the tree after the branches for simple land plants.

Using the scale bar, determine the diameter of the nucleus of the cell on the left, giving the units.
Answers
The diameter of the nucleus of the cell on the left is 1000 nanometers, using the scale bar.
How to determine the diameter of the nucleus?The diameter of the nucleus can be determined by using a scale bar. A scale bar is a line that is drawn on an image to indicate the size of the objects in the image. The scale bar is usually measured in micrometers (µm) or nanometers (nm).
The scale bar on the image is 400 nanometers. The nucleus of the cell on the left is approximately 2.5 times the length of the scale bar. Therefore, the diameter of the nucleus is approximately 1000 nanometers.
Diameter of nucleus = 2.5 × 400 nm = 1000 nm.

the diagram represents protein synthesis which is essential to the function of all cells. what is represented by C?
Answers
The part of the diagram that represents transcription is C.
What is the essential part of every cell?Transcription simply means the process where the information that's in a strand of DNA is copied into a new molecule of messenger.It should be noted that transcription takes place in a nucleus. The diagram depicted represents structures and processes involved in protein synthesis in an animal cell. The part of the diagram that represents transcription is X.As the name implies, protein synthesis, involves the synthesis of proteins in a cell. Cellular structures in a cell called organelles are responsible for this function. These organelles include ribosome and rough endoplasmic reticulum.The ribosome is an organelle found in all cell types and is the site for the synthesis of proteins in the cell. The ribosome is where translation (process of synthesizing amino acid chains from mRNA) occurs. The chains of amino acid later becomes the protein.The Rough endoplasmic reticulum (RER) gets it "roughness" from the fact that RIBOSOMES are attached to its surface. Due to this, the RER functions in the synthesis of proteins. The RER is involved in the production, folding and packaging of proteins in eukaryotic cells. The RER processes the polypeptide produced by the ribosome into proteins that are carried to varying destinations.To learn more about cells refer to:

Answers
The two pieces of evidence that support the theory of the expanding universe are the red shift of light from distant stars and the existence of cosmic background radiation.
The correct answer is option B.
1. Red shift of light from distant stars: The observation of redshift in the light coming from distant galaxies provides evidence for the expansion of the universe. Redshift occurs when the light waves from an object moving away from an observer are stretched, causing a shift towards longer wavelengths. This phenomenon is consistent with the Doppler effect, where the wavelength of light appears to stretch as the source moves away. The redshift of light from distant stars indicates that galaxies are moving away from us and from each other, supporting the idea that the universe is expanding.
2. Existence of cosmic background radiation: The discovery of cosmic background radiation further supports the theory of the expanding universe. Cosmic background radiation is a faint, uniform microwave radiation that permeates the entire universe. It is believed to be residual radiation from the Big Bang, the initial event that is thought to have initiated the expansion of the universe. The presence of cosmic background radiation provides strong evidence for the hot, dense early stages of the universe and its subsequent expansion.
Based on the information provided in the diagram, it is not possible to determine the identity or nature of the celestial objects labeled X. The diagram only represents the expansion of the universe over time and does not provide specific details about individual celestial objects.

By presenting a magnified image of how minute structures and samples interact with visible light, such as their absorption, reflection, and scattering, light microscopy is used to make them visible.
Light microscopes are employed for routine use when low magnification and resolution are sufficient as well as for the study of living cells. Higher magnifications and higher quality images are available with electron microscopes, but they cannot be utilized to see living cells.

What is the purpose of natural selection?
Answers
Answer:
The purpose of natural selection is not a conscious or intentional one, as it is not driven by a specific goal or purpose. Instead, natural selection is a fundamental process in biology that acts on heritable traits within populations over generations. It is a key mechanism of evolution.
Explanation:
The primary outcome of natural selection is the adaptation of organisms to their environment. Individuals with traits that are advantageous in a particular environment are more likely to survive, reproduce, and pass on those beneficial traits to their offspring. Conversely, individuals with traits that are disadvantageous are less likely to survive and reproduce, leading to a reduction in the frequency of those traits in the population over time.
Natural selection, therefore, acts as a filter that shapes the characteristics of populations, favoring traits that enhance an organism's survival and reproductive success in a given environment. Over many generations, this process can lead to the development of new species or the modification of existing ones, as populations accumulate adaptations that allow them to thrive in different ecological niches.
It's important to note that natural selection does not have an end goal in mind, nor does it necessarily lead to the "best" or most advanced organisms. Instead, it is a consequence of the interactions between organisms and their environment, constantly shaping and refining the traits of living beings based on their ability to survive and reproduce.
