Answer:
the bladder stores pee, so you can let it out when your bladder gets full.
b. Decoding
c. Observation
d. Communication
Answer:
Option B
Explanation:
The process of converting a message into a form where it can be transmitted as signals from the sender to the receiver is called as encoding. However, the process of the reconverting the encoded message into intelligible forms so that a receiver could understand the message is called as decoding. However, the entire process of encoding and decoding is known as communication.
For example -
In order to decode a sound signals, analogue from digital are retrieved.
Hence, option B is correct
Answer:b
Explanation:
increased photosynthesis
b.
increased plant mortality
c.
increased crop productivity
d.
increased plant growth
Answer:
increased plant mortality
Explanation:
The rise of carbon dioxide in the atmosphere will definitely bring about increased in photosynthesis.
Photosynthesis in plants is a process whereby green plant produces nutrient in the present of sunlight from carbon dioxide and water. Photosynthesis is a necessity for plants to supply nutrient to the plants . The chemical equation for photosynthesis can be represented as follows:
6CO2 + 6H2O sunlight → C6H1206 + 6O2
Photosynthesis converts light energy into chemical energy. Green plants in the presence of sunlight uses CO2 and H2O to produce food. Increase carbon dioxide will definitely increase crop productivity and plant growth. The more the carbon dioxide and water in the presence of sunlight nutrient are added to the plant.
Plant will definitely not die because of rise in CO2.
Answer: Hemostasis includes three steps that occur in a rapid sequence:
Explanation: 1) vascular spasm, or vasoconstriction, a brief and intense contraction of blood vessels; (2) formation of a platelet plug; and (3) blood clotting or coagulation, which reinforces the platelet plug with fibrin mesh that acts as a glue to hold the clot.
or:
The Blood Clotting Process
Injury. A small tear in a blood vessel wall (for example, from a cut on the skin or an internal injury) causes bleeding.
Vessel constriction. To control blood loss the blood vessel narrows (called constriction), thus limiting blood flow through the vessel.
Platelet plug. ...
Fibrin clot.
Answer:
1) group
2) period
3) numbers of valence electrons
4) increases
Explanation:
When we move in a periodic table from top to bottom or vice versa along a vertical column , it is said that we are moving along a "group" in a periodic table.
Like wise when we move in a periodic table from left to right or right to left in a horizontal row , it is said that we are moving along a "period" in a periodic table.
The classification of elements belonging to any specific group of periodic table is dependent on the total number of valence electron. All elements of with in a group have same number of valence electrons however, the orbitals may change.
The atomic number increases while moving from left to right as the number of orbitals in which the valence electron is found also increase in the same direction.
A vertical column of elements in the periodic table is called a group
A horizontal row of elements in the periodic table is called a period
Atoms of elements in the same group have the same numbers of valence electrons
As you move from left to right on the periodic table, the atomic number increases
1) group
2) period
3) numbers of valence electrons
4) increases
Answer: The correct answer is-
A. organs, but no true body cavity.
Based on the presence of body cavity ( also called coelom), multicellular animals can be classified as acoelomates ( no true body cavity), coelomates ( having true body cavity), pseudocoelomates ( false body cavity).
Roundworms are pseudocoelomic. This means that organs are present but the body cavity is not lined by mesodermal epithelium.
Body cavity is present between the external wall of body and the intestine and it baths the different body organs.
Thus, option A) is the right answer.
Answer:
Option A
Explanation:
All bilateral organisms have coelomates (cavity). However a Pseudocoelomate organism have a false cavity. By false cavity, we mean that there is a body cavity which is filled with fluid and all internal organs bathe in it including alimentary canal system , reproductive system etc. Unlike a coelom, Pseudocoelomate organism do not have body cavity completely lined with mesodermal cells.
hence, option A is correct
