Earth systems include the biosphere, atmosphere, and geosphere. Use the model to explain how photosynthesis acts to transfer carbon
between two Earth systems.
Answer:
Photosynthesis serves as a process of transferring carbon between the atmosphere and the biosphere by using carbon dioxide present in the atmosphere to produce sugars found in plants.
Note: The model is found in the attachment below
Explanation:
The atmosphere is the layer of gases forming an envelop around the earth. The earth's atmosphere is composed of mainly nitrogen and oxygen as well as other gases such as carbon dioxide and water vapor.
The biosphere refers to the regions of the earth's surface on which living organisms can be found. It includes the land, air and water.
Carbon dioxide is cycled between the atmosphere and the biosphere by the process of photosynthesis which is the process by which green plants manufacture their food with the aid of energy from sunlight.
From the model, in the first stage, energy of sunlight is trapped by light-dependent reactions and is used it to make ATP and NADPH. During the second stage, the light-independent reactions use ATP and NADPH reduce carbon dioxide from the atmosphere to sugars and ADP and NADP⁺.
Thus, photosynthesis serves as a process of transferring carbon between the atmosphere and the biosphere.

meisosis I don't rember how to spell it lol. But I believe that it is the answer
Explanation:
Cellular Respiration and photosynthesis are related in that they are opposite of each other. The products of one process are the reactants of the other.
True
False
Answer:
This statement is true.
Explanation:
because during photosynthesis , oxygen is produced because of the reaction of carbon dioxide, and water in the presence of sunlight. oxygen and glucose are synthesized during photosynthesis while on the other hand, oxygen is used in respiration and carbon dioxide is produced which again used by plants.

An example of a place with a microclimate is
a. a mountain range capped with ice.
c. an orchid growing in a rain forest.
b.a forested park in a desert city.
d. coniferous trees in a temperate forest.
An example of a place with a microclimate is a forested park in a desert city. The correct option is b.
What is a microclimate?
A microclimate is a small and distinctive climatic area that can be artificial or natural. It is present in between another big climatic area. Examples are a park, a valley, a part of a city, etc.
A desert is an area where only sand is present because these areas are very dry and very less vegetation is present here. The vegetation is adapted to the desert climate.
A forested park will be a green area that contains trees and animals. The deserted area is different from the forest area. So a forested area will be a microclimate in the deserted areas.
Thus, the correct option is b. a forested park in a desert city.

How does a lion get its source of nitrogen to form its DNA or proteins?
Answer: The protein in their diets
Explanation:
The lion gets its source of nitrogen to form protein in its diet.
What is protein?Proteins are macronutrients that are present in foods. There are two types of proteins. Essential and nonessential. Non-essential proteins are synthesized in the body and essential proteins are needed to eat by taking food.
A lion is an animal, and animals synthesize some proteins in their body, and some proteins are to be taken from the food. Protein is necessary for the growth of the body. It gives strength to the body.
The protein synthesis is done in the cell of the animals. But the nitrogen, that the animals get is from the diet they eat which is meat and plants. It depended upon its diet. Some animals are carnivorous and some are herbivorous.
Therefore, the lions get their protein from their diet.

Which describes the two cells formed through mitosis?
They are identical to each other but unlike the parent cell.
They are different from each other and the parent cell.
They are identical to each other and to the parent cell.
Answer:
The third one.
Explanation:
Mitosis doubles the DNA and then splits the cell in two so it will have identical daughter cells.
Answer:
They are identical to each other and to the parent cell.
Explanation:
Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.

heterogeneous mixture
Explanation:
A heterogeneous mixture contains particles that are not the same, can be separated by physical means, and are not distributed the same throughout the mixture. Trail mix fits this description perfectly.
Trail mix is a heterogeneous mixture, which is in option D, as trail mix is a popular snack that typically consists of a combination of various ingredients, such as dried fruits, nuts, seeds, and sometimes chocolates or candies.
Trail mix is a type of snack that typically consists of a combination of ingredients like dried fruits, nuts, seeds, and sometimes chocolates or candies. These ingredients are intentionally mixed together to provide a variety of flavors, textures, and nutritional elements. Unlike homogeneous mixtures, where the components are uniformly distributed and appear the same throughout, heterogeneous mixtures have visible differences and variations within the mixture. In the case of trail mix, you can see the separation between the various ingredients, and they can be easily distinguished from one another.

. What dam that is still under construction will replace the current tallest dam?
Answer:
Oroville dam
Explanation:
Carbon (C)
Atomic #: 6
Atomic Mass: 12
Question: Calculate the number of electrons using the information given. Write the number on the line and then draw the electrons into the Bohr model.
Assuming the atom has a neutral charge, the number of electrons will be the same as the number of protons. The number of protons is given by the atomic number, 6, so there are six electrons.
The first "ring" of the atom (closest to the center) can take two electrons, so draw two electrons there. The second (outer) "ring" of the atom can take the remaining electrons, so draw four electrons there.
Atomic mass is irrelevant in this specific problem.

Explain how a compound microscope allows you to see magnified images.
Answer:
The classic compound microscope magnifies in two steps : first with an objective lens that produces an enlarged image of the object in a "real" image plane. This real image is then magnified by the ocular lens or eyepiece to produce the virtual image. Two convex lenses can form a microscope.
Explanation:
Answer:
it has multiple magnifying glasses in the scope.
Explanation:
A compound light microscope uses two lenses at the same time to view objects-the objective lens, which gathers light and magnifies the image of the object, and the ocular lens, which one looks through and which further magnifies the image. ... it also allows light to pass to the ocular lens.

Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins. Be sure to describe the steps in the process of protein synthesis. Use information from the lesson to support your response.
Answer:
The sequence of bases in a DNA molecule can determine the order of amino acids in a protein molecule. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence of bases (genetic information) on DNA that codes for a protein is called a gene .
Explanation:
DNA is a genetic material that is made up of two polynucleotide chains.
The structure of a protein is determined by the structure of DNA :
DNA helps in protein synthesis by giving one template in it to produce the mRNA. So if there are any changes in the sequence of DNA, it will affect the protein sequence.
Process of protein synthesisThe process of protein synthesis happens in two phases:The first is transcription, in which the conversion of the DNA into mRNA happens.Transcription occurs in three steps, initiation, elongation, and termination.In the initiation, the DNA strands open up with the help of polymerase enzyme.In elongation, one template of the DNA acts as a template to produce mRNA. The mRNA produced.In the termination, the mRNA template is separated from the DNA and the termination code arrived.The second is translation, in which the mRNA is converted into protein.This is carried out in three steps, initiation, elongation, and termination.In the initiation, the ribosomal units combined with the mRNA.During the elongation, the ribosomal units continue to translate each codon.In termination, the stop codons are reached and there is no codons to translate so the process stop.Thus, that's how protein synthesis occurs.
