Answer:
System that receives and transmits information and responses, in addition to work with electrical impulses is the Nervous system.
Explanation:
The nervous system (NS) is responsible for the control of all the organs and functions of the body. The neuron is the functional unit of this system, allowing the transmission of information through nerve impulses, generated by the difference in potential of its cell membrane.
NS is divided into:
Central nervous system (CNS) —where the brain, spinal cord and other structures are located— in charge of receiving, processing and sending information. Peripheral Nervous System (PNS), a network of nerve fibers in charge of receiving the stimuli and conducting the information to and from the CNS.The integration of both NSC and NSP allows an organism to fulfill all its functions, both voluntarily and involuntarily.
amaging a world without plants. will it be different world. think and write two lines on this
Life could not exist on Earth without trees because they produce most of the oxygen that humans and wildlife breathe. Trees absorb carbon dioxide from the atmosphere and release oxygen using the process of photosynthesis. There would also be no rain without trees since trees absorb water from the soil and release it through evapotranspiration. Water vapor released through evapotranspiration is the major mechanism by which air is remoistened. Forests act as giant air filters for the world. Trees purify the air by absorbing pollutants such as sulfur dioxide and nitrogen dioxide, reducing pollution. Trees also help prevent topsoil erosion because they break the force of wind and rain on soil, their roots bind the soil, and their decayed, falling leaves are absorbed by the earth and enrich the soil. Trees conserve rainwater and reduce water runoff and sediment deposit after storms.Additionally, trees provide a supply of lumber, seeds, and fruit. Further, dead trees that fall and get

6. How are winds in the northern hemisphere differen
from winds in the southern hemisphere?
Answer:
Generally, prevailing winds blow east-west rather than north-south. This happens because Earth's rotation generates what is known as the Coriolis effect. The Coriolis effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

Under normal conditions, gases diffuse through small holes in the leaves of a plant. When the weather is very hot and dry, plants may close these openings to conserve water. How are the closures most likely to affect photosynthesis? O They increase the rate of photosynthesis by increasing the amount of water in the leaf They decrease the rate of photosynthesis by preventing carbon dioxide from entering the leaf They increase the rate of photosynthesis by increasing the amount of oxygen in the leaf They have little or no effect on photosynthesis because gases do not take part in the process
Answer:
They increase the rate of photosynthesis by increasing the amount of water in the plant.
Explanation:
It is hot and dry when these openings close, so the Sun has to be out. Photosythesis is caused when the Sun and water are used by a plant to make food.
The answer to the question should be they increase the rate of photosynthesis by increasing the amount of water in the plant.
A diagram of photosynthesis is below.
The closures that are most likely to affect photosynthesis are they increasing the rate of photosynthesis by increasing the amount of water in the plant. The correct option is A.
What is photosynthesis?Photosynthesis, the method used by plants and other autotrophic organisms to make food, converts carbon dioxide into glucose and oxygen, both of which are vital for life.
Photosynthesis depends on some factors. These factors are water, sunlight, and carbon dioxide. If there is a scarcity of any factors, it impacts the process of photosynthesis. If the water does not get enough water, it will dry and there is less chlorophyll for the plant to carry out photosynthesis.
Therefore, the correct option is A. They increase the rate of photosynthesis by increasing the amount of water in the leaf.

In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, Ovov. Horses with two Ov copies, OvOv, die soon after birth and are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov. The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there are spots everywhere. Two Lp alleles, LpLp, produce the fewspot phenotype, in which the horse is mostly white with colored spots. A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from Lp is indistinguishable from the white from Ov.
Number of:
Solid:____
Fewspot:_____
White Overo:______
Answer:
Hello your question is incomplete below is the missing part

After Pedro had breakfast, he went for a run. Identify at least three energy transformations that had to take place to allow Pedro to complete his run. Then use evidence to support the claim that energy in this system was conserved as it was transformed.
Answer:
When Pedro ate breakfast, he consumed chemical energy. Chemical energy is a form of potential energy and that potential energy was stored in his breakfast. When he went out for a run, the chemical energy transformed into mechanical energy, which is a form of kinetic energy. The mechanical energy then transforms into thermal energy when he is running. While running his temperature started to rise which caused him to sweat. The energy in his system was conserved as it was transformed because the energy was constant. When the energy was being transformed between different types, the total amount of energy remained the same.

Large areas on the leaves of some plants lack chlorophyll and are therefore not green in color. How does this most likely affect photosynthesis? Not enough sunlight is captured in these areas of the leaves. Carbon dioxide cannot enter these areas of the leaves. Too much glucose builds up in these areas of the leaves. Oxygen cannot be released in these areas of the leaves.
(Not enough sunlight is captured in these areas of the leaves)
The plants are of green color due to the pigment chlorophyll. the chlorophyll plays a crucial role in photosynthesis, the process of preparing food.
The correct answer is:
Option A. Not enough sunlight is captured in these areas of the leaves.
The functioning of chlorophyll can be explained as:
Chlorophyll is the green color pigment present in the chloroplast of the leaves. The pigment is involved in the capturing of sunlight and imparting green colors to the plants. The plants lacking chlorophyll will not be able to perform photosynthesis. The process of preparing food in the presence of sunlight, chlorophyll, and carbon dioxide. The products of photosynthesis are oxygen and sugar molecules.
Thus, the correct answer is Option A.
