Reptiles' capacity to deposit amniotic eggs is the main trait that enables them to live exclusively on land. Amniotic eggs have a protective shell around them and include specific membranes that give the growing embryo a self-contained aquatic environment. Amniotic reproduction is the name given to this adaptation.
The amniotic egg has a number of crucial characteristics that let it thrive on land. These qualities consist of:
Shell: By minimizing water loss, the embryo's shell protects it physically and keeps it from desiccating (drying out).
Amnion: The amnion is a membrane that covers the embryo and holds amniotic fluid, which acts as a cushion and source of buoyancy.
The chorion is an additional membrane that encircles the amnion. By facilitating gas exchange, it allows carbon dioxide to leave and oxygen to enter the egg.
The allantois is a sac-like organ that aids in breathing and stores metabolic waste products from the developing embryo.
Egg yolk sac: The yolk sac is a source of proteins, lipids, and minerals that feed the growing embryo.

B. The completed plant tissues and the cells that initiate their growth
C. The relationship between different structures in a plant and their functions
D. The types of plant cells and their functions within the plant
The given image shows the relationship between different structures in a plant and their functions.
What are the structures of plants and their functions?
There are various plant parts, each with its unique characteristics and functions to do. Each one of them plays a vital role in maintaining a healthy ecology and environment.
The parts of the plant include
Roots: The most crucial component of a plant is its roots. They are located underground and make up a plant's root system. They are responsible for holding the plant in place with the soil. They serve as an anchor that the plant uses to keep itself steady. By soaking up water, nutrients, and minerals from the soil, they also control the health of the plant. A plant can grow as a result of these. Additionally, they keep food supplies for later use.Stems: It is the second most crucial component. It rises above the ground, starts out green, and eventually turns brown as it gets older. They consist of leaves, fruits, and flowers and sustain the plant's stalk system. They support the framework and structure of the plantLeaves: Chlorophyll, which is responsible for the synthesis of plant food, can be found there. To prepare the food, it makes use of water, carbon dioxide, and sunlight. A leaf is further divided into three main parts: the petiole, leaf base, and lamina.Flowers: There are certain plants that do not have flowers. They have a vibrant, peaceful aesthetic. They are the plant's reproductive system. Petals, sepals, stamens, and pistils are its four main constituent components.Fruits: Fruit production is carried out by flowering plants. After fertilization, the fully developed ovary transforms into a fruit. They develop into a seed first, then a fruit.Learn more about plants here:

Which of the following is not a function of the bacterial cell wall?
A. Provide the cell with shape and rigidity
B. Prevent the cell from lysing
C. Protect the cell
D. Provide the cell with locomotion
Answer:
D
Explanation:
I believe locomotion would be the job of the flagellum
The correct option that is not a function of the bacterial cell wall is : ( D ) Provide the cell with locomotion
The Bacterial cell wall acts mainly as a protective cover to the cell of the bacterium, protecting the cell from lysing ( preventing the breakdown of the cell via osmotic pressure ). The cell wall also provides the cell with shape a and rigidity.
While The locomotion of the cell is not the responsibility of the cell wall but it is made possible by the flagellum.
Hence the non - function of a bacterial cell wall is providing the cell with locomotion.

The stems of bamboo, a tropical grass, can grow at the phenomenal rate of 0.3 m/day under optimal conditions. Given that the stems are composed almost entirely of cellulose fibers oriented in the direction of growth, calculate the number of sugar residues per second that must be added enzymatically to growing cellulose chains to account for the growth rate. Each D-glucose unit contributes ~0.5 nm to the length of a cellulose molecule.
Answer:
Approximately 6944 glucose residues are added enzymatically per second
Explanation:
Cellulose is the main structural polysaccharides in plants. It is composed of unbranched glucose monomer units linked to each other by beta 1-4 glycosidic bonds.
The cell wall and stem of plants cells are composed of cellulose fibers. They provide rigidity and support to the plant.
In the given bamboo plant, the enzymatic addition of glucose units to the growing cellulose fiber chains results in the phenomenal growth rate of the bamboo stem.
Since each glucose unit contributes ~0.5 nm to the length of a cellulose molecule, number of glucose units required for daily growth is calculated as follows:
0.5 nm = 10⁻⁹
0.3 m/0.5 x 10⁻⁹ m = 600000000 units of glucose per day
Number of seconds in a day = 24 * 60 * 60 = 86400 seconds
Number of glucose residues added per second = 600000000/86400
Number of glucose residues added per second = 6944.4 glucose molecules per second
Therefore, approximately 6944 glucose residues are added per second

like marble. What processes must have acted on the limestone over the years to change this
sedimentary material into hard metamorphic material?
Answer:
The heat generated by the magma chamber has changed these sedimentary rocks into the metamorphic rocks marble, quartzite, an hornfels. Regional Metamorphism occurs over a much larger area. This metamorphism produces rocks such as gneiss and schist. ... They are generally as hard and sometimes harder than igneous rocks.
If sedimentary rock, pressed inside the crust and treated with a high pressure and temperature, then it can change over time into a hard metamorphic rock.
What is a sedimentary rock?A sedimentary rock is mad up by the decomposition of minerals and other organic matter near the water surface.
