What is the function of the central vacuole in plants? (a) Stores water and dissolved nutrients (b) Carries out photosynthesis (c) Releases energy from stored nutrients (d) Protects the genetic material of the cell
Answers
Answer:
The correct answer is - option A. stores water and dissolved nutrients.
Explanation:
The central vacuole is a large vacuole in the plant cell that is made up of small vacuoles after combining together. The central vacuole plays many roles in the plant cell such as support the cell with the help of turgor pressure.
t stores water inside with dissolving other substances and nutrients such as salts, minerals, proteins and help in the growth of the plants. This structure store the nutrients and substances temporarily.
Thus, the correct answer is - option A.
Which type of population pyramid occurs in locations where fertility rates are high, death rates fall, and more people
are middle aged with a longer life expectancy?

Answer:
the polymerase chain reaction (PCR)
recombinant DNA
plasmids
genetic markers
Explanation:
The answer is "the polymerase chain reaction (PCR), recombinant DNA, plasmids, and genetic markers".
Fill in the blank:To generate multiple copies of DNA sequences, researchers employ a technique known as polymerase chain reaction (PCR). Recombination of the DNA can also be created by combining DNA from two sources. Bacteria with circular DNA molecules known as plasmids could be one of the origins. Generic markers could be used to identify microorganisms that have undergone a transformation.Find out more about the DNA cloning here:

Dissemination facilitated
Active transport
Endocytosis
Phagocytosis
Pinocitosis
Exocytosis
Answers
Answer: cellular membrane: The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
Explanation:
passive transport Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. Instead of using cellular energy, like active transport, passive transport relies on the second law of thermodynamics to drive the movement of substances across cell membranes.
True or false:
The oceans influence earth’s atmosphere?
Answers
Answer:
true
Explanation:
the answer should be true.
Explanation: the ocean influences climate by absorbing solar radiation and releasing head needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years to millions of years.

What is on a transplanted organ that causes the transplant recipient's body to reject it?
Answers
Answer:
Major histocompatibility complex (MHC) antigens
Explanation:
The process in which recipient body rejects the transplanted organ is called a allograft rejection or transplantation rejection.
A transplanted organ contains Major histocompatibility complex (MHC) antigens which are required to be accepted by the recipient's body to function properly but T cells in recipient's body become alloreactive and recognize MHC antigens (donor-derived antigens) as foreign and starts making antibodies against it. Which means the recipient's body is rejecting the transplanted organ.
Hence, the correct answer is "Major histocompatibility complex (MHC) antigens".

The chemical formulas are aluminum bromide (AlBr₃), magnesium bromide (MgBr₂), sodium sulfide (Na₂S), and the chemical compound formula of the sodium nitride is Na₃N.
What is the significance of the chemical formulas?Chemical formulas are important to identify the chemical composition of the mixture as they provide important information about the types and numbers of atoms present in a molecule or compound and also predict the properties of a substance, such as its melting point and boiling point. This is useful in industries such as manufacturing, agriculture, etc which has significant importance in the field of medicine, as it helps researchers understand how the human body interacts with the drug.
Hence, the chemical formulas are aluminum bromide (AlBr₃), magnesium bromide (MgBr₂), sodium sulfide (Na₂S), and the chemical compound formula of the sodium nitride is Na₃N.

Light energy is near the sunrays.carbon dioxide is given by the plant respiration that is leaf.Glucose is stored inside the tissues or the body of the plant.Explanation:
The plant performs a chemical activity of photosynthesis under the light during the daytime. During this process, the visible part of the spectrum reflects back the other spectrum of light. The plants produce oxygen and take in carbon at the same time they also provide carbon dioxide. Glucose is a type of energy available in starch is stored in plant leaf carbon dioxide is used to convert into sugar to form glucose.Answer:
