how does your skin protect you
Answer:
Your skin protects you by having the immune system.
Explanation:
Your skin produces the covering of cells, and has an immune system that protects you from becoming ill.
Answer:
The skin acts as a natural barrier between the outside environment and our body in both the macro and micro world.
Explanation:
The skin protects our organs and tissues from the outside environment, preventing other organisms like bacteria from stealing our body's nutrients and harming our body's cells. It also protects us in the event that our body is hit with something (for example, a fall).
7. a) How does a vaccine relate to the virus that it protects against? (1 point)
Answer: A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response. These molecules are called antigens, and they are present on all viruses and bacteria.
Explanation:
Despite being farther from the sun and mercury, Venus has a much warmer temperature. What accounts for Venus’s temperature being higher than Mercury’s? Also if anyone is in environmental science and can help me with the answers I would appreciate it.
Explanation: Despite being farther from the sun and mercury, Venus has a much warmer temperature. Because Venus is closer to the sun than Earth is, it receives more solar energy than Earth does. Much of this radiation is reflected by Venus's clouds, but some radiation reaches the surface and is later given off as heat. The carbon dioxide in Venus's atmosphere traps heat so well that Venus has the hottest surface among the planets. This trapping of heat by the atmosphere is called the greenhouse effect. The Venus has thick atmosphere than Mercury.
I hope this helps you.

What is green house effect?Venus is significantly warmer even though it is further away from the sun and mercury. Venus receives more solar energy than Earth does because it is nearer to the sun. The clouds of Venus reflect most of this radiation, although some energy does reach the surface and is later converted to heat. Venus has the warmest surface temperature of all the planets due to how strongly the atmosphere of the gas carbon dioxide traps heat. This trapping of heat by the atmosphere is called the greenhouse effect. The Venus has thick atmosphere than Mercury.

✔ spring

An underground layer of permeable rock that is situated between two layers of impermeable rock so that water is trapped within it is called a(n)
✔ confined aquifer
.
Explanation:
I did the instruction.
Springs and confined aquifers are formed respectively due to the process explained above.
What is spring and aquifer?The water that is already there is subjected to increased pressure as new water from precipitation "recharges" or enters the aquifer. This pressure forces the water to migrate through the fissures and tunnels that are contained within the aquifer, and the water then spontaneously emerges to the surface at locations that are known as springs.
As a result of the fact that confined aquifers are shielded from local sources of contamination (such as subterranean storage tanks and septic systems, for example), the water that they produce is generally suitable for consumption.
A natural release point of underground water at the surface of the ground or immediately into the bed of a stream, lake, or sea is referred to as a spring. Spring water can flow straight into the bed of these bodies of water.

State the law of conservation of energy. According to this law, how is the total amount of energy affected in any process (like a swinging pendullum or bowling ball hitting the pins)?
Answer:
The law of conservation of energy is that energy can not be created or destroyed. This means that it can only be transferred from one form of energy to another. In any situation the total amount of energy is, let's say for example a ball rolling down a hill, both the potential and kinetic energy is combined to find the total energy. The total amount will be the same in a process because the amount of potential energy or kinetic energy can only transfer to what is already being used. Example, say the total energy will be on a pie chart, let's say 1/4 of the graph is potential and 3/4 is kinetic. No matter what, the pie graph will be 4/4.
Compare AND contrast primary and secondary succession.
Answer:
Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
Explanation:
Answer:
The basic difference between primary and secondary succession is the presence of soil. When primary succession begins, soil is not present; in the case of secondary succession, soil is already in place.

Hypothesize how the properties of water protect the aquatic organisms living in a temperate-
climate pond during both the summer and winter months.
Couple sentences
Answer:
Hydrogen bonds make water molecules spread out when they freeze. This makes ice less dense than water and allows ice to float. If ice did not float then oceans and lakes would freeze from the bottom up, killing marine life by trapping organisms in the ice. When ice floats, it insulates the water below, keeping it at around 4 degrees C or 40F, which does not freeze and allows fish to survive the winter.

two new species of plants were introduced into an area that was low in available nitrogen compounds in the soil. one formed nodules and one did not. which species would you reasonably expect to grow more robustly?
explain.
Answer:
The plants with the nodule will grow faster
Explanation:
The plants which has the nodule possesses a bacteria called Rhizobium which helps in the fixation of nitrogen to the soil and the relationship is a symbiotic one. When the Bacteria fixes the nitrogen into the soil the plants with the nodule has the advantage of nitrogen uptake in the soil before the ones who don’t possess the nodules.

In Linneaus's book Systema Naturae, minerals were originally included while classifying living things.
But, minerals were later removed from this classification. What characteristic of science does this show?
A. Scientific knowledge is rigid.
B. Scientific knowledge is permanent.
C. New evidence emerges by chance.
D. New interpretations are a part of science
Answer:
Option-D
Explanation:
Carolus Linnaeus gave the three kingdom classification of organisms that is plants, animals and mineral kingdom.
He included various features which were mostly morphological and kept living organisms into plants and animals and non-living things into his mineral kingdom. This mineral kingdom was later removed from the classification system.
The removal of the mineral kingdom shows that the interpretations can be a part of science and science is not permanent but changes with time. The advances and development in science shows are the results of new interpretations in science.
Thus, Option-D is correct.
