Answer:
(2) the placenta allows nutrients to diffuse from the mother to the embryo.
Explanation:
The placenta is a shared organ between the mother and the embryo. It diffuses the necessary nutrients from the mother to the future baby and the residues from this one to the mother, so that she can expel them. The placenta separates the mothers and the embryo blood, but it allows the diffusion of said nutrients and wastes through especial parts of the placenta with thin walls.
According to natural selection, individuals that tend to survive are those that have which of the following?
the ability to quickly produce the most offspring
the largest and strongest body structures
the genetic variations that are best suited for their environment
the longest legs and fastest running speeds
Answer:
The genetic variations that are best suited for their enviornment
Explanation:
Those that are not well suited for their environment will die off, leaving only the ones that are suited for it. This species will slowly take hold until the species has adapted and become a completely different one.
Answer:
The genetic variations that are best suited for their environment
Explanation:
This way they may also have a chance to evolve if natural selection kept going until everyone of the species had that trait.
Which part of the carbon cycle occurs when plants, trees, or fossil fuels are burned?
A. Transpiration B. Oxidation C. Photosynthesis D. Combustion
Answer:
Combustion.
Explanation:
It's just as it sounds, combustion is the process of burning something. In the carbon cycle, combustion occurs whenever any organic living or non-living thing is burned in the proximity of oxygen, afterwards producing carbon dioxide.
Combustion is the part of the carbon cycle which occurs when plants, trees, or fossil fuels are burned. Thus, the correct option is D.
What is Combustion?Combustion or burning is a high-temperature exothermic redox chemical reaction which occurs between a fuel and an oxidant. The oxidant is usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. This is one of the major reasons of pollution.
Three main types of combustion include rapid combustion, spontaneous combustion, and explosive combustion.
Therefore, the correct option is D.

A nebula is composed of dust and gas, but what are the elements in a nebula?
Answer:
the person above has correct
Explanation:
"Nebulae are made of dust and gases—mostly hydrogen and helium. ... Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star."
Which statement describes the epiphyseal plate? It is where flat bones are actively growing. It is where old bone cells are being remodeled. It is where cartilage cells are being turned into bone cells. It is where the bones in a baby's skull are growing together.
Answer:
The correct answer is - It is where cartilage cells are being turned into bone cells.
Explanation:
The epiphyseal plate is a plate of cartilage that is found at the end of each long bone, is a location for the longitudinal growth of the bones that are responsible for the height or long bone growth of an individual.
It is the site that is responsible for the formation of the cartilage bones by the process of proliferation of cells and hypertrophy of the cell which is then turned into the bones. This change takes place due to calcification, degradation, and replacement by osseous tissues.
Answer: c.) It is where cartilage cells are being turned into bone cells.
Explanation: The epiphyseal plate is also known as the growth plate. This is the site of bone elongation, where cartilage cells are being converted to bone cells
what is the difference between redshift and blueshift?
Answer:

A component of a circuit changes, as shown below. How would this change affect the electric circuit? A switch is closed, so the circuit would be incomplete and broken and the lights in the circuit would not shine. A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine. A switch is opened, so the circuit would be incomplete and broken and the lights in the circuit would not shine. A switch is opened, so the circuit would be complete and unbroken and the lights in the circuit would shine. Mark this and return Save and Exit
Answer:
A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine.
Explanation:
The image shows an open switch to a closed switch.
A closed switch represents a complete circuit, and an open switch represents an incomplete circuit. The lights would shine and the circuit would be complete because the switch is now closed.
The change affects the electric circuit as A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine. The correct option is B.
What is an electric circuit?When an electric charge builds up inside of an object, it disperses across its surface and stays there until it can be discharged by an electrical current or electrical discharge; this is known as "static electricity."
From an open switch to a closed switch is shown in the image. An incomplete circuit is represented by an open switch, and a complete circuit is by a closed switch. The switch is now closed, so the lights would turn on and the circuit would be complete.
Therefore, the correct option is B. A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine.

A cell that has 6 chromosomes in the G2 phase will have how many sister chromatids during that same phase
Answer:
12 chromatids.
Explanation:
If a cell has 6 chromosomes in the G2 phase will have 12 sister chromatids during that same phase because replication of chromosomes occurs which produces two exact copies of each chromosomes. Then 6 chromatids are distributed in one daughter cell while the other 6 chromatids are distributed in other daughter cell and finally the cell division occurs.

In Units 4A and 4B, we have learned about photosynthesis and cellular respiration. Which of the following statements is true?
a. The reactants of photosynthesis are the reactants of cellular respiration.
b. Photosynthesis produces light energy while cellular respiration produces chemical energy.
c. The products of photosynthesis are the reactants of cellular respiration.
d. Photosynthesis and cellular respiration use light energy to convert to chemical energy.
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
