bazaltina [42]

Answer:

Intially the glucose concentration is levelled and then the liquid level in side A will rise.

Explanation:

Initially the liquid ob both sides are in isotonic condition.
The membrane is permeable to glucose so glucose will diffuse from higher concentration (2 M) to lower concentration (1 M) until the concentration become equal (1.5 M) on both sides.
Know, the Side A have 2 M sucrose and 1.5 M glucose and side B have 1 M glucose and 1 M sucrose.
The side A will become hypertonic and side B will become hypotonic and water will start moving from side B to side A.

Answer:

Neutrophil
Neutrophil
Eosinophil
Basophil
Red blood cell
Monocyte
Neutrophil
Monocyte
Lymphocyte
Megakaryocyte
Formed elements
Eosinophil
Basophil
Lymphocyte
Red blood cell
Plasma
Monocyte
Basophil

Explanation:

A. Red blood cell: Blood cell that is a product of the medulla. These cells contain hemoglobin that carries oxygen from the lungs to the rest of the body.

B. Megakaryocyte: Big cell easy to recognize for its size. Differs from other cells for being polyploid, growing by endomitosis, and being bigger. They have important biological functions. The most important one is the formation of plaquettes, necessary for hemostasia, damaged vessels reparation, and tissue healing.

C. Eosinophil: Granulosites. Immune System cells, active during infections, pathologies, inflammations, and allergies. Originated in the medulla and transported to the blood and organs. One of their functions is to defend the organisms from parasite infections, helping to destroy the pathogen.

D. Basophil: Granulosites. Immune System cells. in the medulla and transported to the blood. Only when there are parasite infections they can be present in tissues and organs. They release substances such as histamine that make possible the inflammatory process.

E. Monocyte: Agranulocyte phagocyte. Originated in the medulla and transported to the rest of the body. They differentiate into macrophages in tissues. They defend the body from bacteria and viruses. When monocyte values are elevated, usually means that there is an important process of infection.

F. Neutrophil: Phagocytic Leucocytes polymorphonuclear found in the peripheric blood. Compose the first defense line against bacterial and fungal infections. Product of the medulla and transported to the blood. They are the first to arrive at the affected tissue, followed by lymphocytes and macrophages.

G. Lymphocyte: Leucocyte. There are two types of lymphocytes: B cells, which can produce antibodies in the presence of bacteria, viruses, and toxins. T cells can destroy infected cells from the body. They all circulate in the blood.

H. Formed elements: Elements that might be found suspended in the plasma. These include all the mentioned cells and cell fragments

I. Plasma: Transparent, acellular, and kind of yellow liquid that represents 55% of the blood volume.

How do lichens alter the abiotic environments to favor the establishment of other species of plants?

BabaBlast [244]

The lichens show mutualism and they are found in every biome of the Earth. The lichens have algae and fungus associated with them and they live in a mutualistic relationship with each other. Lichens can grow on soil where no other species can grow like rocks, barren soils and they enrich the soil on dying where other plants and trees can grow.

Lichens being pioneer species change the environment by building up the soil and liberating nutrients. Also the lichens contribute to the chemical weathering of the soil releasing phosphate along with erosion and weather conditions.

When the simple plants die, the wildflowers and other plants start growing replacing lichens or mosses.

From the above explanation it can be concluded that lichens alter the abiotic environment and favor other species of plants to grow by breaking down rocks from soil and providing nutrients.
