Answer: Evolution and Migration
Explanation: When evolution occurs genes can be passed on through natural selection. The gene flows occur when there is migration because they can be transferred from different types of populations.
l. A farming area developed a major locust problem. Swarms of locusts were destroying crops and the environment. A team of
scientists developed an infectious disease that would reduce the population of locusts What would be most important to find
out before producing and releasing the disease?
how a decreased number of locusts would affect other organisms
which species might eat the crops in the absence of locusts
how the disease can be used for other applications
O how quickly farmers would get to see the results
Answer: how a decreased number of locusts would affect other organisms.
Explanation:
When engaging in any action aimed at destroying large numbers of an organism as is the case here, there is always a need to check what impact it might have on the ecosystem at large.
This is why it is very important that the effect of a decreased number of locusts on other organisms is evaluated before such drastic action is taken. If it would lead to a situation where the ecosystem is destabilized, the consequences would be far reaching and very damaging.
How a decreased number of locusts would affect other organisms is the
most important to find out before producing the disease.
What is Population?This is referred to the number of organisms present in an area over a
specific period of time.
We were told that swarms of locusts destroyed the environment and
needed to be reduced through the creation of a disease. The effect the
decrease in locust has on other organisms has to be considered to ensure
the ecosystem is balanced and doesn't adversely affect others.

The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.
How Oxygen from the air is absorbed?Oxygen from the air is absorbed into the bloodstream through the lungs. When it reaches the lungs, the function of the cardiovascular system begins, since that is where the non-oxygenated blood is oxygenated and returns to the heart.
When in the cardiovascular system, the blood reaches the capillaries in the tissues, oxygen is released, which the cells use to produce energy. These cells release waste products, such as carbon dioxide and water, which are absorbed and transported by the blood.
O2 and CO2 are constantly circulating and passing from one medium to another, so much so that O2 passes, along with other gases, from the atmosphere to the airways, entering through the nostrils and driving through the larynx, trachea, source bronchi, terminal bronchioles, respiratory bronchioles, alveolar sacs and alveoli.
Therefore, The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.

How do the nutrients found in plants function in plant DNA? Is the function of plant DNA similar to human DNA?
Answer:
How do the nutrients found in plants function in plant DNA?
Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
Is the function of plant DNA similar to human DNA?
How much DNA do plants share with humans? Over 99%? ALL animals and plants share the same DNA which is basically a code of only 4 'letters' which code for the same amino acids from which all proteins are made.

Matter and energy both can neither be created or destroyed
True or false
Please explain thank you!
Answer:
true
Explanation:
Both the initial and final substances are composed of atoms because all matter is composed of atoms. According to the law of conservation of matter, matter is neither created nor destroyed, so we must have the same number and type of atoms after the chemical change as were present before the chemical change.

What is the tectonic theory?
The theory of plate tectonics plates says that Earth's surface is made of rigid slabs of rock, or plates, that move to each other.
What is a tectonic plate?
They are huge slabs of rock that cover the earths mantle When a earthquake occurs that's because the tectonic plate is breaking that makes the ground shake During the earthquake and afterward, the plates keep on shaking until they are stuck again!

The plate tectonic theory gave the concept of land and sea formation. "Ocean floor evidence of seafloor spreading" acted as evidence to support the plate theory. Thus, option A is correct.
What is plate tectonic theory?The plate tectonic theory states about the formation of the lithosphere by the movement of the plate tectonics located deep in the mantle and core layer of the earth. These plates show movement slides over each other to produce lands and drifts to form the oceans.
At a very early there was a supercontinent, Pangaea that slowly shows the formation of the current continent by the movement of the tectonic plates. These solid hard rocks of the earth layers allowed the formation of the various land formations.
The seafloor spreading is the best evidence that supports the tectonic plate theory that described the formation of the oceanic structures including the trenches and basins. The geological structures of the ocean floors supported the theory.
Therefore, option A. evidence of seafloor spreading supported the plate tectonic theory.

Which of the following are internal cellular conditions?
A) temperature, pH, water concentration, salt concentration
B) sunlight, dry environment, wind
Answer: a
Explanation:
The following are internal cellular conditions :
A) temperature, pH, water concentration, salt concentration.
Temperature facilitates deciding what can input or depart the cellular and the way properly molecules observed inside the membrane can function. Temperatures that might be too excessive or too low can severely harm and, in the intense temperature ranges, kill the cellular via their impact at the cellular membrane.
Physiologically ordinary intracellular pH is maximum generally among 7.0 and 7.4, even though there may be variability among tissues (e.g., mammalian skeletal muscle has a tendency to have a pHi of 6.8–7.1). There is likewise a pH version throughout special organelles, that can span from round 4.5to 8.0.
Water concentration:
Water molecules flow into and out of the cell at an identical fee, so the length stays constant. then a cell. This method of water attention is better within the cell than outside. Thus, water flows out of them, inflicting them to shrivel or maybe die.
Salt concentration:
Increase of the way of life medium NaCl attention from a hundred and 20 mm to 220 mm ended in a reduced boom fee and a boom in the content material of ribonucleic acid (RNA), protein, and lipide phosphate consistent. Cell quantity becomes likewise increased.
