The
store(s) more carbon than the atmosphere.
O rock
trees
oceans
Osoil
Answer:
Oceans
The oceans are a massive carbon sink, and part of the positive reinforcement of the greenhouse gas cycle is that, as the oceans become warmer, then tend to release more carbon dioxide dissolved in the water which in turn drives temperatures warmer.

Which of the following shows the stage of mitosis in the correct order?
Prophase, prometaphase, metaphase, anaphase, telophase, cytokinesis is the correct order of mitosis. Therefore, option (B) is correct.
Mitosis is a cellular process that ensures the accurate division of a cell's genetic material into two identical daughter cells. It consists of several distinct phases that occur in a specific order.
Interphase: The cell prepares for division by growing, duplicating its DNA, and synthesizing necessary proteins.
Prophase: Chromatin condenses into visible chromosomes, the nuclear membrane disintegrates, and spindle fibers form.
Metaphase: Chromosomes align at the center of the cell, known as the metaphase plate, and attach to spindle fibers at their centromeres.
Anaphase: Sister chromatids separate and are pulled to opposite ends of the cell by the spindle fibers.
Telophase: Chromosomes reach the opposite poles of the cell, and new nuclear membranes form around them. The chromosomes begin to decondense.
Cytokinesis: The cytoplasm divides, leading to the formation of two distinct daughter cells, each containing a complete set of chromosomes.

Which BEST describes the result of this mutation?
A
The entire sequence of amino acids is changed.
B
The RNA strand does not code for the correct amino acids.
С
The change in amino acids shortens the polypeptide sequence.
D
The alternation of a single nucleotide encodes for a different amino acid.
Answer:
A . The entire sequence of amino acids is changed.
Explanation:
The entire sequence of amino acids is changed when the mutation occurs in the protein because amino acid is the building block from which protein is made. Mutation is the sudden change that is occur in the genetic makeup i.e. DNA when the cell is exposed to radioactive radiation of chemicals. So due to this change, the sequence of amino acids changed and they work differently.
What prevents blood from circulating backward in veins?
A.valves
B. capillaries
C. lungs
D. heart
Answer:
A.Valves
Explanation:
The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium. As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve. When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.

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.

The arrows in a food chain show: a Who eats who b Heat energy being lost c The movement of energy between organisms d The route of food to the shops
Answer:
c The movement of energy between organisms
Explanation:
Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.
The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).
This ultimately implies that, the arrows in a food chain show the movement of energy between organisms such as from producers which are autotrophs or self-feeders such as plants to the tertiary consumers.
Furthermore, a list of the types of organisms in an eco pyramid are;
I. Producers: these are autotrophs or self-feeders such as plants.
II. Primary consumers: these are herbivores that typically feed on plants such as a goat or deer.
III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.
IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.
Answer: The arrows in a food chain show (The movement of energy between organisms). The correct option is C.
Explanation:
In an ecosystem, a food chain shows the transfer of energy and nutrients ( food) from organisms to organisms in a feeding pathway. Instead of giving functional group names such as primary producer, primary consumer and so on, in a good chain, the organism at each step is identified. Thus,
Grass-------> Zebra ---------> lion
(Primary (Primary ( secondary
producer). consumer) consumer)
this is an example of a simple food chain in a grassland ecosystem. This ARROWS represented above shows the direction of energy flow through an ecosystem.
Furthermore, the grass traps solar energy and stores it as chemical energy in the food made during photosynthesis. When eaten by Zebra, which is the primary consumer, the energy stored in the grass is transferred to the consumer. This transfer is inefficient as some of the stored chemical energy is lost as heat. When the zebra is eaten by a Lion,which is the secondary consumer.
