explain briefly the process of nutrition in amoeba
Explanation:
amoeba is an microscopic unicellular organism found in the moist soil ponds and lakes. When amoeba comes in contact with food ,it produces pseudopodia around the food particles the food get trapped in food vacuole. Digestive juices are secreted into the food vacuole to digest the food. The digested food is absorbed and used for production of energy. the undigested food present in the food vacuole, is expelled. from the amoeba, by the process of egestion
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.

In the previous activity, you chose an animal that interested you and listed three examples of innate behavior and three examples of learned behavior for that animal. Now research what, if any, courtship and mating rituals this animal has. Explain why you think it has or doesn’t have these behaviors.
Answer:
what grade
Explanation:
Courtship and mating rituals are diverse and can vary greatly among different animal species. They are typically involved in attracting mates, establishing pair bonds, and ensuring successful reproduction.
1. Courtship and Mating Rituals Exist: Many animal species have elaborate courtship and mating rituals. These behaviors can serve various purposes, such as displaying fitness and attractiveness to potential mates, establishing territory, or demonstrating parental abilities.
2. Absence of Courtship and Mating Rituals: Some animal species may not exhibit elaborate courtship or mating rituals. This can occur in species where mating opportunities are abundant or where the reproductive process is straightforward without the need for elaborate displays.
The presence or absence of courtship and mating rituals can depend on various factors, including ecological pressures, social structure, reproductive strategies, and evolutionary history of the species. Different species have evolved different strategies to maximize their reproductive success, and these strategies can manifest as complex courtship rituals or simpler methods of attracting mates.

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:

Why are plants unable to grow at the bottom of lakes ?
Answer:
I think its because of the water pressure
Explanation:
Answer:
I'm guessing that it's because there isn't enough sunlight at the bottom of a lake. The water reflects light, and plants need enough sunlight since they use photosynthesis to get their energy.
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.

Identify the strengths and weaknesses of Mendel’s Law of Independent Assortment.
Answer:
Explanation:
Mendel propel two laws The law of inheritance and that of independent assortment of gene.
Independent assortment of gene explain that alleles of a gene assort independently and that different Allele can show different phenotypic effect and differences. This means that in a gene where we have 2 allele they can both show individual difference where one can have a dominant effect over the other and the other allele is recessive.
This law does not take care of linked gene where alleles don't separate after crossing over sister chromatids but are rather inherited together given rise to complex inheritance.
