Answer:
competition can cause the population to decrease.
Explanation:
Answer:
The relationship between competition correlates with population.
Explanation:
If there is no competition on a certain set of species, the population would rise drastically, However, if there is more competition for every species, the population would decrease due to more competition for resources.
True or False: In Biology, Fitness refers to how fast and strong an individual is. Explain.
Answer:
False
Explanation:
The biological fitness of a person's organism is dependent on their ability to survive and reproduce in a given environment. If different traits or alleles increase the fitness of an organism, those alleles will consequently increase in the gene pool, and that trait will increase in the population. This is how natural selection affects a population.

B. they both produce chemical and electrical energy.
C. they are both key components of solar panels.
D. they both use energy from the sun to separate electrons from atoms.
Answer:
D. They both use energy from the sun to separate electrons from atoms.
Explanation:
In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH.
Photovoltaic systems use the photons produced by sunlight to generate direct current (DC) electricity. When the photons hit the panel they are absorbed by the panel's semiconducting silicon material.
true or false: light energy from the sun can be stored in the bonds of the carbohydrates, glucose
Answer:
True
Explanation:
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars).

What is the mass number when it is stable?
Answer:
The mass number (symbol A, from the German word Atomgewicht [atomic weight]),[1] also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. It is approximately equal to the atomic (also known as isotopic) mass of the atom expressed in atomic mass units. Since protons and neutrons are both baryons, the mass number A is identical with the baryon number B as of the nucleus as of the whole atom or ion. The mass number is different for each different isotope of a chemical element. Hence, the difference between the mass number and the atomic number Z gives the number of neutrons (N) in a given nucleus: N = A − Z.[2]
The mass number is written either after the element name or as a superscript to the left of an element's symbol. For example, the most common isotope of carbon is carbon-12, or 12
C
, which has 6 protons and 6 neutrons. The full isotope symbol would also have the atomic number (Z) as a subscript to the left of the element symbol directly below the mass number: 12
6C

Which of the following can be inferred from the diagram above that shows the dependence of potential Energy on the Internuclear distance between two atoms?
A)The atoms form a bond with a bond length of 25 pm
B)The atoms form a bond with a bond length of 75 pm
с)The net force between the atoms is attractive at 25 pm
D)The net force between the atoms is attractive at 75 pm
Answer:
A)The atoms form a bond with a bond length of 75 pm
Explanation:
The Morse curve is a plot of potential energy against internuclear distance between two atoms.
When two atoms are far apart, the bond energy is zero, this means that there is no significant interaction between the both atoms. Hence, when two atoms are positioned at infinite distance from each other, they do not interact with each other appreciably. At internuclear distance within the range of atomic diameter, attractive forces predominate between atoms. At shorter distances repulsive forces predominate and the energy of system is quite high. The minimum point in the plot of a Morse curve represents equilibrium between attractive and repulsive forces.
The internuclear distance that corresponds to this minimum point is known as the equilibrium bond length.
For the plot shown in the question, the minimum point occurs at an internuclear distance of 75pm. This corresponds to the bond length of the system.
Tratando-se sobre atividades aeróbias, segundo Cooper (1972), qual das alternativas abaixo não está correta? a) Aumento da eficiência dos pulmões e coração. b) Aumento das cavidades do coração, aumento do volume total de sangue e volume máximo de oxigênio (aumento da absorção, captação e transporte de oxigênio). c) Aumento do número e tamanho dos vasos sanguíneos. d) Melhora da tonicidade muscular e dos vasos sanguíneos. e) Diminuição do colesterol bom (HDL), aumento do colesterol mal (LDL) URGENTE
Answer:
Diminuição do colesterol bom (HDL), aumento do colesterol mal (LDL)
Explanation.
Esto debe revertirse, debe ser una disminución del colesterol malo y un aumento del colesterol bueno.
Básicamente, el ejercicio aumenta el HDL y reduce los triglicéridos. En condiciones normales, los ejercicios aeróbicos no reducen el LDL. Sin embargo, cuando se combina con cambios en la dieta y una pérdida de peso bien controlada, el efecto combinado podría reducir el LDL.
En las condiciones estándar, el ejercicio recomendado por semana es de 150 minutos de ejercicios suaves o 75 minutos de ejercicio vigoroso por semana.
Por lo tanto, cuando se calcula por semana, esto sería un promedio de 20 minutos de ejercicio por día.
Andar en bicicleta, caminar, hacer jardinería y aeróbicos acuáticos son ejemplos prácticos de ejercicios leves o moderados que podrían aumentar el HDL. Sin embargo, el baile aeróbico, el trote y el salto de cuerda son ejemplos de ejercicios vigorosos que, cuando se combinan con la dieta y la pérdida de peso, conducen a una disminución del LDL.
This should be reversed, it should be a decrease in bad cholesterol and an increase in good cholesterol.
Basically, exercise boosts the HDL and lower triglycerides. Under normal conditions, Aerobic exercises do not reduce LDL. However, when combined with dietary changes and well-monitored weight loss the combined effect could lower LDL.
Under the standard conditions, the recommended exercise per week is 150 minutes of mild exercises or 75 minutes of vigorous exercise per week.
Therefore, when calculated per week this would be an average of 20 minutes of exercise per day.
Biking, walking, Gardening, and water aerobic are practical examples of mild or moderate exercises that could boost HDL. However, Aerobic dancing, jogging, and rope jumping are examples of vigorous exercises which when combined with dieting and weight losses leads to a lowering of LDL.
Escribe lo que piensa de la siguiente suposición si es cierta o no: " Todas las semillas de una fruta sobrevivirán, se convertirán en adultas y tendrán sus propias frutas. " Describa de si esta suposición es verdadera para otros organismos como las bacterias y animales además de las plantas)
Answer:
Esta suposición no es realista, muchas de las semillas no llegarán a la etapa adulta y por lo tanto no podrán generar nueva progenie
Explanation:
Acorde a la teoría de la evolución por selección natural planteada por Darwin, solamente aquellos organismos que se encuentren mejor adaptados al ambiente en el que viven podrán sobrevivir y de este modo perpetuar sus genes en la progenie. Este es un principio que aplica a todos los tipos de organismos vivientes (es decir, plantas, animales, bacterias, etc). Darwin definió a este proceso evolutivo como 'descendencia con modificación', donde aquellos organismos que se encuentren mejor adaptados a su ambiente transmitirán sus rasgos a la descendencia, mientras que aquellos que no se encuentren suficientemente adaptados no podrán sobrevivir.
Explain why diversity is important for the survival of a species?
Answer:
The importance of genetic diversity. More specifically, genetic diversity can be a species natural defence system against disease and survival even under extreme weather conditions but more importantly, genetic diversity can help weed out unfavourable traits in species which maximises opportunities for thriving in any environment². hoped it helped.
Explanation:
Increased genetic diversity leads to increased chance of species survival. Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity.

Mrs. Canales pointed to an apple sitting on her desk.
She asked her students to describe any forces acting
on the apple. This is what some of her stu-
dents said.
Archie: "The only force acting on the
apple is air pressure."
Sam: "There is one force acting on the apple. Gravity is the force that pulls on
the apple."
Soledad: "There are two forces: the desk pushes up on the apple and gravity pulls
downward on the apple."
Misha: "There are many forces acting on the apple; but, it is the holding force in the
apple that keeps it on the desk."
Tess: "There are no forces acting on the apple because the desk stops any forces
from acting on it."
Which student do you most agree with?
Answer:
Misha
Explanation:
Archie, Soledad and Sam are right about the types forces, but not how many. Misha is the only one who says there are multiple. Tess is just wrong.

what is different between leaching and erosion
Erosion is the natural process by which soil / rock are removed from the Earth's surface by exogenetic processes whereas Leaching is the removal of soluble material from soil or other material by percolating water.
What do you mean by soil erosion?Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, and animals.
Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
Removing trees and plants, plowing fields, and overgrazing by livestock disrupts roots that stabilize sediment and soil. These human activities can increase erosion rates 10 to 100 times that of non-human geologic processes.

Check Some flatworms reproduce through fragmentation. What is a disadvantage of this method?
1.) It is a very slow process relative to sexual reproduction.
2.) It is a process that leads to lower genetic diversity than sexual reproduction
3.) It is a process that does not result in many offspring relative to sexual reproduction
4.)It is a much more complex process than sexual reproduction.
Answer:
it is a process that leads to lower genetic diversity than sexual reproduction
Following are the disadvantages of this method:
It is a very slow process relative to sexual reproduction.It is a process that leads to lower genetic diversity than sexual reproduction.Fragmentation is a method of reproduction that occurs when an organism breaks into smaller pieces, which then grow into new individuals. While this process can be efficient in certain circumstances, it has several disadvantages compared to sexual reproduction. One disadvantage is that it is a very slow process relative to sexual reproduction. This is because it takes time for the fragments to grow and develop into new individuals, and there may be many steps involved in this process.
Additionally, fragmentation leads to lower genetic diversity than sexual reproduction, because the offspring are identical to the parent organism, rather than being the result of a mixing of genetic material from two different parents. These factors may make fragmentation a less effective method of reproduction in some circumstances.
