B. Organelles
C. Molecules
D. Vessels
The organs of vascular plants consist of layers of specialized tissues which are the vascular tissues. The correct answer is option A.
What are the major parts of a vascular plants ?The parts of the vascular plants are roots, stems and leaves.
Vascular tissue in the plants is just made of the two of the specialized types of the conducting tissues that are xylem that conducts water and phloem that conducts the sugars and organic compounds. A single type of the vascular bundle that always has both xylem along with the phloem tissues.
The vascular plant that is the sporophyte basically has three basic categories of the non-reproductive or vegetative organs. These are roots, stems and leaves.

1. When a bridge-like structure forms between bacteria and genetic material is exchanged, bacteria are reproducing through which process?
A. Binary fission
B. Transformation
C. Transduction
D. Conjugation
Answer:
D. Conjugation
Explanation:
Bacterial conjugation is the transfer of genetic material between Bacterial cell by direct cell-to-cell or by bridge like connection between two cells.
The process in which the formation of a bridge-like structure takes place between bacteria to exchange genetic material is known as conjugation and thus option D is correct.
Bacteria is a prokaryotic cell and it has developed various methods for the purpose of genetic recombination. Genetic recombination is significant for genetic diversity. The 3 most common methods used by bacteria for the diversification of their DNA are namely Transduction, Transformation, and Conjugation.
The Conjugation process is explained as follows:
The Conjugation process in Bacteria is explained as the genetic material transfer between bacterial cells by direct contact between cells or by a connection formed by a bridge-like structure between the cells. The pilus plays a significant role in forming a connection between 2 cells. With the help of the formed contact, the plasmid can be able to transfer its own copy to the recipient bacterial cell which results in exchanging of genetic material.Thus, we can conclude that the conjugation process in bacteria can cause the formation of a bridge-like structure to exchange genetic material and option D is the correct answer.

What organelle wouldn’t have a job if the smooth and rough ER didn’t work?
Answer: The Golgi apparatus.
Explanation: I believe it is the Golgi apparatus as the Rough ER and Smooth ER create proteins and sort them in to piles before sending to the Golgi apparatus to deliver.
The Smooth ER and Rough ER are like the suppliers while the Golgi apparatus is like the transporter.
Remember: Proteins have many functions and are needed severely to perform those actions that without the Golgi apparatus, those proteins wouldn’t be able to be transported.
How does mitochondria help the cell get the material it needs
Answer:
Known as the “powerhouses of the cell,” mitochondria produce the energy necessary for the cell's survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.
Make a list of countries/states around the world that insects currently do not reside in.
Answer:
Iceland, and states like Washington DC. , South Dakota, Connecticut, Idaho, New Hampshire, Delaware, North Dakota, Illinois.
Explanation:
Iceland is one of the only places where people live without insects.
The reason why Iceland does not have mosquitos or other insects is its oceanic climate that keeps them away.
The insects freeze 3 times a year, which makes their survival in Iceland impossible.
The other states are not completely insect-free, however, their number is so small that is considered as like they don't exist.

Answer:
the answer is true.
Weber’s law defined that noticeable difference is a constant proportion. So the given statement is true.
Weber law:In the case when there should be the size of the noticeable difference i.e. delta I should represent the constant proportion with respect to the original stimulus value.
Hence, we can say that Weber’s law defined that noticeable difference is a constant proportion. So the given statement is true.

In photosynthesis, ____________________ energy is transformed into __________________energy and _______________________ gas is released. In cellular respiration, ________________ is broken down and __________ gas is released.
Answer:
Fill in the blanks:
In photosynthesis, light energy is transformed chemical energy carbon dioxide gas is released. In cellular respiration, a glucose molecule is broken down and carbon dioxide gas is released.
Explanation: Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct. During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
