Answer:
- Strength: cells can carry out specialized tasks
- Weakness: cells cannot carry out functions of another cell types
Explanation:
Cells are highly specialized biological units designed to carry out specific metabolic functions (e.g., growth, replication, development, etc). Each cell type exhibits a specific gene expression pattern related to its specific function. For example, in undifferentiated stem cells, specific signaling pathways are associated with the differentiation process. On the other hand, cell weakness is associated with the same phenomenon, cells are not able to carry out all cellular functions and therefore they need to work together to sustain the life of the whole organism.
Which is the layer underground where all empty spaces are filled with water?
O A. Zone of aeration
B. Water table
C. Impermeable rock
D. Zone of saturation
Answer: The saturated zone
Explanation: the saturated zone, the level in which the pores of the soil or rock are completely filled with water
Hope it helps :)
The layer underground where all empty spaces are filled with water is called the Zone of Saturation. Therefore, the correct answer is D. Zone of Saturation.
What area is the zone of saturation ?The zone of saturation is the area below the water table where all pore spaces in the soil and rock are completely filled with water. This water is referred to as groundwater, and it is an important natural resource that can be used for drinking water, irrigation, and other purposes.
The depth and thickness of the zone of saturation can vary depending on factors such as the permeability of the soil and rock, the amount of precipitation, and the rate of groundwater recharge.
The water table is the boundary between the zone of saturation and the zone of aeration, which is the layer of soil and rock above the water table where the pore spaces are partially filled with water and air.
The water table can rise or fall depending on factors such as precipitation, evaporation, and groundwater pumping. When the water table rises, it can cause the zone of saturation to expand, which can lead to flooding or create new areas of wetlands.
Impermeable rock is rock that does not allow water to pass through it, which can create barriers to the movement of groundwater. Impermeable rock can occur in layers or as individual formations that are surrounded by more permeable rock.
In some cases, impermeable rock can create aquifers, which are layers of permeable rock that are sandwiched between impermeable layers and hold significant amounts of groundwater.
Overall, understanding the characteristics and behavior of the zone of saturation is important for managing and protecting groundwater resources. Groundwater is a critical source of water for many communities and ecosystems, and ensuring its sustainability and quality is essential for supporting human and environmental well-being.

Which hormone is responsible for the development of the male secondary sex characteristics?
O estrogen
O progestin
O progesterone
testosterone
The answer is D on 2021 edge :)
Answer:
Testosterone
Explanation:
The hormone that is responsible for the development of the male secondary sex characteristics is testosterone, which is the last option as testosterone is a steroid hormone produced primarily in the testes of males.
What is the significance of testosterone in males?Testosterone plays a crucial role in the development and maintenance of male sexual characteristics that have positive influence on body. It induces the development of sperm, and in puberty, it triggers the development of the male secondary sexual characteristics, which affect many aspects of male health and well-being, including bone density, so testosterone is important.
Hence, the hormone that is responsible for the development of the male secondary sex characteristics is testosterone, which is the last option as testosterone is a steroid hormone produced primarily in the testes of males.

a. What type of organism is the grass?
Answer: it’s a producer
Explanation: The grass is a producer because it produces food while other animals get food themselves.
The grass is the producer of the food chain. Producers are the organisms in the food chain which produce food in a food chain.
What are the producers in a food chain?Producers are the organisms which make their own food in a food chain through photosynthesis. Producers are also known as autotrophs. They get energy to work from the chemicals or the sunlight, and with the help of water, these organisms convert the light energy into useable energy that is the chemical energy in the form of sugar or food particles. The most common example of a producer are the green plants.
Producers are any kind of green plants. Green plants make their food by taking sunlight and using this energy to make glucose (carbohydrate). The plant uses this carbohydrate, also called glucose to synthesize many products, such as wood, leaves, roots, and bark. Grasses are also an example of producers in a food chain as they produce glucose.

W
Inside of cell
Answer:
Explanation:
A cell membrane is composed of two phospholipid layers in which each molecule contains a single phosphate head and two lipid, or fatty acid, tails. The heads align along the inner and outer boundaries of the cell membrane, while the tails occupy the space in between. Only small, nonpolar molecules can pass through the membrane through simple diffusion. The lipid tails reject polar, or partially charged, molecules, which include many water-soluble substances such as glucose. However, the cell membrane is peppered with transmembrane proteins that provide passage to molecules that the tails would otherwise block.
