1. Which of the following might be a result of adding a secondary consumer to the aquatic ecosystem in the accompanying illustra

MatroZZZ [7]

Answer:

<u>Option-(A): </u>In an illustrated flowchart, the movement of carbon atoms through an aquatic food chain is indicated by arrows.
<u>Option-(C)-</u> An increase in the population of scavengers.

Explanation:

The ecological pyramid is comprised of different level of organisms as the energy flow occur through them in a more directed form inside the different spheres depending upon the medium for energy transmission across the given parameters or area. As, the arrow provides us with a more directed way for understanding the transmission of energy through different organisms and there respective levels inside the ecological pyramid.

While, the increase in the level of scavengers or the animals which consumes the left overs of other living beings is balanced with the addition of the secondary consumers to the aquatic ecosystem.As, it will provide equal chances and energy to the different beings inside the ecosystem.

If there are 10 chromosomes in a particular cell at the start of prophase how many will be present in the same cell at the end o

Ilia_Sergeevich [38]

Answer:

20 chromosomes

Explanation:

Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.

In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.

Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.

From deep to superficial, the order of the strata of the epidermis is corneum - granulosum - lucidum - spinosum - basale. spinos

kotykmax [81]

Answer:

basale - spinosum - granulosum - lucidum - corneum.

Explanation:

The order of strata in the epidermis:

Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.
Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.
Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.
Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.
Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.
