Answer and Explanation:
Water's high specific heat means that the temperature of the water takes a long time to change. Living things that live near bodies of water experience temperatures different than inland, which is typically advantageous. During the summer, water remains cooler than the air for a period of time, and in the winter, the water remains warmer than the air for a period of time. In turn, the air in the areas with a body of water is typically increased or decreased a few degrees in temperature depending on the season. In the winter, this also produces what is called the "lake effect", in which snow is produced during cooler atmospheric conditions when a cold air mass moves across long expanses of warmer lake water.
The Serengeti region of Africa contains a population of cheetahs and a population of lions. Studies have shown that the cheetah population has very low genetic diversity, while the genetic diversity of the lion population is quite high. The cheetah population is also much smaller than the lion population. Both populations are vulnerable to infection with a particular virus that can be fatal in both species. What is the most likely outcome if both populations are infected with this virus?
A.
The cheetah population is more likely to survive because there are fewer individuals for the virus to attack.
B.
The lion population is more likely to survive because larger populations are immune to viruses.
C.
The cheetah population is more likely to survive because lower genetic diversity increases immunity to viruses.
D.
The lion population is more likely to survive because it is more likely to have individuals with traits to combat the virus.
Answer:
D. The lion population is more likely to survive because it is more likely to have individuals with traits to combat the virus.
Explanation:
Since lions have greater genetic diversity it is likely that there's one or two lions that have a trait to resist or kill the virus thus won't be infected, whereas, since cheetah's have low genetic diversity and low population size it is likely that they have little to no chance to surviving this virus attack since the genetic makeup is similar among the members of cheetah species.

Answer:
Cell wall and Chloroplasts
Explanation:
I just studied hope its correct (～￣▽￣)～
Answer:
Cell wall and chloroplast
Explanation:
Plant cells are the fundamental building blocks of plants and they are eukaryotic because of the membrane bound organelles and nucleus also found in Animal cells.
Plant cells organelles are chloroplast and cellwall which is not found in animals.
Chloroplast is an organelle which contain the green pigment use for photosynthesis.
Cell wall is an organelle found in plant cell which contain cellulose, hemicellulose, liginin, pectin , soluble protein and microfibrils. It provide strength and protect the plant against mechanical or osmotic stress.
Kai has a see-through glass tank with air, plants, and animals that eat those plants. He sealed the tank so no material can get into or out of it, but light can get in when the tank is not covered.
The light for the tank has been on all day, and Kai measured the carbon in the air and found that it is decreasing. How is carbon moving between the air and the living things in the tank? What is happening to the amount of carbon in living things? Explain your thinking as completely as possible.
Answer:
1. Carbon is moving from the living things in the tank into the air when they respirate, and from the air back into plants via photosynthesis
2. The amount of carbon in living things is increasing as plants use the carbon in the atmosphere, and animals eat the plants.
Explanation:
According to the question, a well sealed tank contains air, plants and animals. Since light can get into the tank, plants can perform photosynthesis. Living things in the tank release carbon in form of carbondioxide (CO2) gas through respiration. Plants then make use of this carbondioxide (CO2) to synthesize carbon-containing food (glucose) in the presence of sunlight. This process is called PHOTOSYNTHESIS.
Animals eat those plants and the stored carbon in the plants gets transferred to them. The animals release this carbon into the air again in the form of carbondioxide when they respire. Hence, carbon in the tank moves from the living things (respiration) into the air and back into plants (photosynthesis).
2. Since the amount of carbon in the air is decreasing, the carbon is being used by the living things in the tank. Plants absorb the carbon in the atmosphere for photosynthesis, then animals eat the plants to get the carbon. Therefore, the amount of carbon in the living things is increasing.
1. Carbon is flowing from the living organisms in the tank into the air by the process of respiration and from the surrounding back into plants via photosynthesis.
The animals in the tank utilize the oxygen when they inhale while during exhalation carbon dioxide is liberated. The carbon dioxide in the tank is used by the aquatic plants to produce food and energy in this way the level of oxygen and carbon dioxide is maintained in the tank.2. The quantity of carbon in living, are expanding as plants use this carbon in the process of photosynthesis from the environment and animals consumes those plants.
The deposited carbon in the food gets spent by the animals and they release this carbon back via exhalation. Therefore the quantity of carbon in living things is increasing.To learn more about respiration and photosynthesis follow the link:

25 percent
O 50 percent
O 75 percent
O 100 percent
Answer:
This is late but the answer is 100%
Explanation:
I got a 100 on the test
The percentage of the offspring that will exhibit red, long-stemmed flowers is 100 percent; that is the last option as all of the offspring will show dominant traits, which are red, long-stemmed.
What is genetic crossing?In the context of genetics, traits are characteristics that are passed down from parents to offspring through their genetic material (DNA). These traits are determined by genes, which are segments of DNA that contain the instructions for the development of a particular characteristic. Here, the gene for flower color in roses has two alleles: R (red) and r (white). The R allele is dominant, and the r allele is recessive. Similarly, the gene for stem length has two alleles: L (long) and l (short). The L allele is dominant, the l allele is recessive, and from the cross, all will be dominant.
Hence, the percentage of the offspring that will exhibit red, long-stemmed flowers is 100 percent; that is the last option.

What is the genotype of the male circled in pink?
Answer:XaY
Explanation
XAY is the genotype of the male circled in pink.
What is the genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype.
The term “genotype” broadly refers to an organism's genetic make-up; in other words, it characterises an organism's whole gene pool. The phrase can also be used to describe the alleles, or different forms of a gene, that an organism carries in a more specific meaning.
The genotype XAY for a male denotes the manifestation of an X-linked dominant characteristic. It is an X-linked dominant illness called fragile X syndrome. If their father has the condition, the sickness will afflict the girls, but not the males.
Therefore, The pink circled male's genotype is XAY.

Sheila weighs 60 kg and is riding a bike. Her momentum on the bike is 340 kg • m/s. The bike hits a rock, which stops it completely and throws Sheila forward onto the pavement. If there is no net force on the system, what is Sheila’s velocity immediately after she is thrown from the bike?
Answer:
5.7 m/s
Explanation:
The computation of Sheila 's velocity right after she gets thrown out of the bike is shown below:
1) The Physical principle: conservation of momentum.
If there is no net external force operating on a system, so the system's total momentum is conserved
The momentum, p, is a vector magnitude that is determined as the product of the mass by the velocity:
P = mv.
2) Taking into account therefore that there is no net force on the device, Sheila and the momentum of the bike are the identical pre and post collision.
Based on this, the calculation is as follows
Momentum before the collision:
[tex]P_1 = (mass\ of\ Sheila + mass\ of\ the\ bike) \times velocity[/tex]
[tex]P_1 = (60kg + m) \times v_1[/tex]
= 340 kg m/s
Now Momentum after the collision:
[tex]P_2 = mass\ of\ sheila \times velocity\ of\ Sheila + mass\ of\ the\ bike \times velocity\ of\ the\ bike[/tex]
[tex]P_2 = 60kg \times v_2 + m \times 0 = 60kg \times v_2[/tex]
[tex]P_1 = P_2[/tex]
[tex]= (60kg + m) \times v_1[/tex]
[tex]= 60kg \times v_2[/tex]
[tex]= 340 kg .\ m/s[/tex]
[tex]= 60kg \times v_2[/tex]
[tex]v_2 = \frac{340\ kg .\ m/s }{60\ kg}[/tex]
= 5.7 m/s
The velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.
The given parameters;
mass of Sheila, m = 60 kgmomentum of Sheila, P = 340 kg.m/sThe velocity of Sheila immediately after she is thrown from the bike is calculated as follows;
P = mv
where;
v is the velocity Sheila
[tex]v = \frac{P}{m} \\\\v = \frac{340}{60} \\\\v = 5.67 \ m/s[/tex]
Thus, the velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.

Consider these three scientific statements
1. The inherited traits of plant, animal, and microbial populations change through time because of differential reproductive success patterns, which are influenced by the way individual organisms interact with their environment.
2. If a certain culture of bacteria is subjected to more ultraviolet radiation than another culture, Then it's reproductive success rate will be reduced.
3. In sexual reproduction, Recessive alleles are always masked by dominant alleles. in other words, the traits of a Recessive allele will not be expressed if a dominant allele is present.
These statements have a lot in common. Each statement is testable, each describes a potential realishionship between observable factors, and each deals with a different aspect of reproduction or inheritance. However, one of the statements is typical of a scientific hypothesis, one is typical of a scientific theory, and one is typical of a scientific law.
Which statement is a hypothesis, which is a theory, and which is a law? "Justify your anwsers"
Answer: 1. Scientific theory
2. Scientific hypothesis
3. Scientific law
Explanation:
The scientific theory can be defined as the aspects of the natural world that are tested and proofed by the scientific methods, involving the observations, measurements and evaluation of the outcome. The scientific theory can be changed with new ideas or evidences. The first statement is a scientific theory because the microbial population may change due to the fact that how microbes interact rather than restricting to the differential reproductive success.
The scientific hypothesis can be defined as the statement that is required to be tested or verified by scientific method. It is based on presumption. The second statement is the example of scientific hypothesis because it is beginning with "if" here it is presumed that if the culture is exposed to ultraviolet radiation then reproductive success rate will be reduced.
The scientific law is based upon facts or evidences obtain after experimental trails or applying the scientific methodology. This cannot be changed with time. The third statement is the Mendel's law of dominance.
