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:

Identify these elements of photosynthesis.
Answer:
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:
left - carbon dioxide
right - glucose
top - light energy

What makes plant material more difficult to digest?
Answer:
Cell walls can make plant material difficult to digest. Many herbivorous mammals have wide molars. These big teeth help them grind up leaves and grasses. Carnivorous mammals, on the other hand, usually have long, sharp teeth that help them grab prey and rip it apart. A group of herbivores called ruminants have specialized stomachs.
Explanation:
Which two parts of sedimentary rocks formation include the breakdown and carrying away of existing rock
Answer:
weathering
erosion
Explanation:
Weathering can be explained as the
breaking down of rocks as well as minerals or dissolving it on the surface of the earth. After the rock has been broken down then the bits of the rock can be transported away in a process known as " Erosion". The agents of
weathering and erosion could be water, salt, animal as well as plants.
It should be noted that the parts of sedimentary rocks formation that include the breakdown is weathering while the parts of sedimentary rocks formation that include carrying away of existing rock is erosion.
Answer:
weathering

What will happen to the parts of the cricket as it travels through the digestive system?
Are there any concerns about certain people consuming crickets?
Answer:
it would be broken down
Explanation:
the digestive systems purpose is to break down food into energy
As the food goes from the very first part of the digestive system it reaches the last part as in its most digested form. The situation is possible because of the digestion.
What is the very first organ of digestive system ?It is the mouth that is solely making enough of digestion as it contains the amylase which is responsible for the digestion of starch.
As the food reaches the mouth it gets mixed with saliva which makes it easier to get break into and the food in this condition is called as bolus where the food will enter into the esophagus that is the food pipe via the peristalsis where the inward and outward movement of food pipe makes it enter the stomach.
In stomach the process of churning takes place where it gets mixed with the digestive juices and the food mixing with the digestive juices breaks into its simpler constituents.

Which of the following could be present in a eukaryotic cell? *
Ribosomes

Cell Membrane
Nucleus
Membrane-Bound Organelles
DNA
Answer:
Ribosomes
Membrane-Bound Organelles
Nucleus
Explanation:
Each eukaryotic cell has a plasma membrane, cytoplasm, a nucleus, ribosomes, mitochondria, peroxisomes, and in some, vacuoles; however, there are some striking differences between animal and plant cells.
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
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.

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.

What is on a transplanted organ that causes the transplant recipient's body to reject it?
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".

Explanation:
Henry puts a plant into a beaker with water. After sometime he added blue ink into it A few hours later he observes that flowers turn from white to blue.
Answer:
The change in color in the flowers is because the plant has absorbed the dyed water. After some hours, we can see that the water has ascended through the roots, the stem and reached the flower petals. We can see the water's path till it evaporates in a process called transpiration, which returns water to the atmosphere.
Explanation:
Plants absorb water and other nutrients so that they can live. When we add ink into the water, we can see the water's path from the roots, up the stem, the leaves, and the flowers. In the flowers, the water evaporates through the stomata. We call this process transpiration. The ink allows us to see that the water was in the petals, but it evaporates, leaving behind the ink. As water evaporates, the plant drinks more, which results in a more intense color in the petals.
