all living things contain carbon.which of the following statements is true about carbon atoms?
I. Each carbon atom can form single bonds with up to four other carbon atoms. II. Each carbon atom can form double bonds with up to two other carbon atoms. III. Carbon atoms can join together to form chains or rings. IV. A single molecule of some compounds can contain thousands of carbon atoms.
Answer:
All the given choices
Explanation:
Carbon is a very interesting element which is the backbone of most organic compounds.
Organic compounds are made up of carbon. Carbon forms a wide range of compound due to the following properties;
An atom of carbon has 4 valence electrons and can bond with 4 other carbon. Carbon can form single, double and triple covalent bonds. They can join together to form rings or chains.Which of the following is NOT an example of a biological process in a geochemical

Tanisha says that the Moon looks dark from Earth when the Moon is in two different places: always when it is closest to the sun, as in Top View #1, and always when it is furthest from the sun, as in Top View #2. Is Tanisha correct? If she is correct, explain why the Moon always looks dark from Earth in both of these positions. If she is incorrect, explain when the Moon looks dark from Earth and how the light on the Moon should look in each of Tanisha’s diagrams.
Tanisha is wrong in her conclusion ( i.e. the moon will appear dark only when it is behind the earth ( furthest away from the sun ) )
The moon gets its light from the sun and the closer the moon is to the sun the more light it gets and is has to be positioned in-between the sun and the earth to have such light rays as well.
When the moon is furthest from the sun it will be positioned behind the sun ( i.e. the earth is in-between the sun and the moon ). during this period the moon will appear dark because the Earth been bigger than the moon sheds away light rays coming from the sun towards the moon.
Hence we can conclude that Tanisha is wrong in her conclusion.

carbohydrates
proteins
lipids
nucleic acids
с
d
Answer:
nucleic acids
Explanation:
The macromolecule Astrid would be studying is the nucleic acids. They contain the genetic materials that would provide useful information for her study.
Nucleic materials are very essential to all life forms. In the broad sense, nuclei materials is the general term for DNA and RNA. These materials contains genetic information that can help Astrid's study. The materials are passed from parents to offspring in the genetic tree.In a complex multicellular

it will be replaced since the specialization of a multi celular organism is that they live longer than the single celled organisms
Why are the processes of oxidation and reduction important to cellular respiration?
Answer:
During aerobic respiration, oxygen is reduced, donating an electron to hydrogen to form water. The entire process of cellular respiration oxidizes glucose. This produces the majority of the energy released in cellular respiration

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.

An atom of element x has one more shell of electrons than an atom of beryllium, but It
has one less valence Electron than beryllium.Which element is element X
Answer:
Sodium
Explanation:
This would leave you with 3 shells of 2, 8, and 1. Since it has one more shell then the second shell has to be 8. Since the first shell can only contain up to 2 it must be 2/8. And since it has one less valence electron than beryllium it must be a config of 2/8 1, which is the electron config of Sodium, Element with Atomic number 11 and electron shell of 2/8 1.
Answer:
Sodium

Based on the diagram shown above the Glycolsis, briefly describe the first step of cellular respiration, emphasizing the location, raw materials needed and the end products.
Answer:
Glycolysis takes place in the cytosol which is part of the cytoplasm of the cell. Glucose is rearranged and phosphorylated to form F-1,6BP(fructose 16 bisphosphate which is very unstable) its splits into 2 phosphorylated 3C sugars (DHAP and G3P)(can interconvert) both form G3P to enter 3rd phase, G3P converted into pyruvate creates 4 ATP in total but has a net of 2 ATP and creates NADH. The raw materials needed are two molecules of NAD+ per glucose as well as 2 ATPs. Hope this helps!

Albinism is a recessive genetic condition in which a person lacks pigment that gives color to the skin. If the allele for albinism is represented as "a," and the functional allele is represented as "A," what will be the genotype of a person with albinism?
Answer:
The correct answer would be - "aa".
Explanation:
Albinism is an autosomal recessive genetic condition which means it will be expressed only if both alleles for the pigmentation are recessive. If a single copy of the dominant allele present with the recessive allele the expression of the recessive allele would be masked by it and skin will be pigmented however they will act as carriers of the condition.
There would be three condition or three allele combination:
AA - no recessive allele so no albinism
Aa - dominant allele with recessive allele which means carrier but pigmented skin
aa - both alleles are recessive so the albinism will be expressed.
Explain positive climate feedback and negative climate feedback
Climate feedbacks: processes that can either amplify or diminish the effects of climate forcings. A feedback that increases an initial warming is called a "positive feedback." A feedback that reduces an initial warming is a "negative feedback."
