Structure 1 is the "cell wall"

Cell wall functions are:-

1. Provide support and limited plasticity.

2. Prevent loss of water

3. Protects from insects and pathogens

4. Prevent over expansion caused by too much water

5.Keep the shape of the plant

6. Allow plants to grow to great heights.

Structure 2 is the "vacuole"

vacuole functions are as follows:-

1.The main function of vacuoles is the storage of many important molecules like amino acids, sugars, various organic acids, and some proteins.

2. In plants, the vacuoles are very large in size and filled with cell sap that helps to maintain the trugidity and rigidity of the cell.

Plant tissues are comprises of cells which are similar and perform a specific function. Plant tissue are of two types meristematic tissue and permanent tissue.

Meristematic tissue comprises undifferentiated cells, that are the building blocks of the specialized plant structures. Meristematic tissues comprises living cells with varied shapes.

Permanent tissue is made of meristematic cells, which has definite form and shape and have lost the power to divide and differentiate and are of three types - simple, complex and special. The simple tissues are of of three types namely parenchyma, sclerenchyma and collenchyma.

Plant tissue allow the maximum elongation of plants to absorb sunlight for the photosynthesis process. Primary phloem can transport the products of photosynthesis from the leaves to other parts of the plants.

For humans, the diploid chromosome number equation is 2n = 46 because humans have two sets of 23 chromosomes The diploid chromosome number varies by organism and ranges from 10 to 50 chromosomes per cell.

Mitosis is a type of cell division that occurs in somatic or body cells. In mitosis, and a cell undergoes division to produce two daughter cells each with the same number of chromosome as the parent cells.

Mitosis produces diploid cells and diploid cells are cells that have the same number of chromosomes as the parent cell.

Answer:The answer is A

Explanation:

I Got it right on the test

Answer: D) it is used to transfer genetic info

Explanation: :)

The right response is OD. Genetic data is transferred through it. A specific kind of RNA molecule known as messenger RNA (mRNA) is in charge of transmitting genetic data from DNA to the ribosome, a cellular component in charge of creating proteins.

The single-stranded nucleotide molecule known as messenger RNA (mRNA) is translated from DNA. The ribosome then converts the sequence of amino acids, which serve as the building blocks for proteins, from the mRNA. When genes are expressed, which is the process of turning DNA-stored information into proteins, mRNA plays a crucial role.

The genetic information contained in DNA and the cell's machinery for protein synthesis are connected through mRNA. Involvement of mRNA in transcription mRNA plays a role in both the transcription of DNA into a series of nucleotides and the translation of that series of nucleotides into a series of amino acids.

The control of gene expression also involves mRNA. It may be applied to control both the time and volume of protein synthesis within a cell. By regulating the quantity of mRNA a gene produces, it may also be used to alter how active a gene is. This may be used to regulate the expression of particular proteins in a cell, which can have a significant impact on the cell's functionality.

Hyaline cartilage makes up the costal cartilage that holds the ribs to the sternum. The most prevalent form of cartilage in the body is hyaline cartilage.

On the articulating surfaces of bones, in the larynx, trachea, and bronchi, as well as on the sternal ends of the ribs, hyaline cartilage is present. It imparts a rigid yet malleable form to the constructions.

Hyaline structures are connective tissues that anchor the ribs onto the sternum. Such structures and joints are robust because collagen fibers are present, but their mobility and flexibility are constrained. To reduce friction and provide cushioning at the joint surface, articular cartilage, also known as hyaline cartilage, covers the ends of bones.

An example of a law is the law of conservation of energy, which has to do with how energy is used. Scientific experiments can be done to observe energy.

An example of a scientific theory is the theory of natural selection. Based off of data and observation, the theory of natural selection has been formulated, and the theory of natural selection explains why.

The average speed by which the car travels according to the given scenario is 108.3 km/hr.

The actual Speed is the calculated speed of the axis as determined by the change in the Transducer Counts status register. Actual Speed is measured in position units per second.

It can be calculated as total distance divided by the total time taken.

According to the given data:

The distance is 1300 km.

Time taken is 12 hrs.

[tex]Average speed = \frac{1300}{12} km/hrs[/tex]

Average speed = 108.33 km/hrs.
