How are ecosystems affected by landslides?
Answer: Landslides can overwhelm, and even pollute streams and waterbodies with excess sediment. In extreme cases they can dam streams and rivers, impacting both water quality and fish habitat. Landslides can wipe out large tracts of forest, destroy wildlife habitat, and remove productive soils from slopes.

9. why Energy released by aerobic and anaerobic respiration in animal are not same.
Answer: Anaerobic respiration produces a relatively lesser amount of energy as compared to aerobic respiration, as glucose is not completely broken down in the absence of oxygen. In animal cells anaerobic respiration often occurs during exercise. The glucose does not get fully broken down in this process, so it does not release its full potential energy. Instead of carbon dioxide and water it breaks down to form lactic acid and a small amount of energy.

Con ayuda de un microscopio se observa una bacteria en el agua transcurridas (2) se miran muchas bacterias . Que ocurrio alli ,que tpo de reproducccion sucedio meiosis o mitosis
Answer:
Ninguna de las dos. No ocurre ni mitosis ni meiosis.
Probablemente haya ocurrido fisión binaria/bipartición.
Explanation:
En este caso estamos hablando de bacterias, organismos unicelulares procariotas. Estos tienen una forma de reproducción asexual denominado fisión binaria. Los eucariotas por su parte pasan por periodos de división celular implicada en el crecimiento denominado mitosis, y división celular implicada en reproducción sexual, denominada meiosis.
La fisión binaria, también conocida como bipartición, si bien muy parecida a la mitosis en algunos aspectos, es la forma de reproducción de las bacterias.
Ambas, mitosis y fisión binaria, implican un duplicado de material genético. El ADN se duplica y una copia va a cada célula hija. Lo mismo sucede con el resto del contenido celular. Finalmente ocurre citocinesis. Sin embargo, a diferencia de la bipartición, la mitosis requiere de mecanismos mucho mas complejos de duplicación celular e involucra también a la cariocinesis, ausente en bacterias.
La fisión binaria ocurre muy rápidamente, en un breve período de tiempo puede hallarse una diferencia considerable en la cantidad de células presentes en un sustrato, producto de esta división. Es por esto que el crecimiento que exhiben las bacterias como población, sigue un modelo exponencial.

• incorporating cardio and strength training into daily workouts
The components of the fitness includes performing muscular movement of the body that requires energy as well as incorporating cardio and strength training into daily workouts. The correct options are b and c.
What is fitness?Physical fitness is defined by professionals as "one's capacity to complete everyday tasks with optimized performance, perseverance, and strength while managing disease, exhaustion, and stress and reducing sedentary behavior."
Physical activity can enhance your brain health, assist you in controlling your weight, lower your risk of developing disease, fortify your bones and muscles, and improve your ability to do everyday tasks.
Individuals who sit very little and engage in moderate-to-vigorous physical activity reap health benefits.
Fitness includes performing muscular movements that require energy, as well as incorporating cardio and strengthening exercises into daily workouts.
Thus, the correct options are b and c.

write two examples of consumers tell whether they are herbivores omnivores carnivors or scavengers
Answers
Lion,Tiger -Carnivores
vulture- scavenger
Cow,sheep -Herbivores
Man, Pig -Omnivores
In an ecosystem, consumers are organisms that obtain their energy and nutrients by feeding on other organisms. They are a vital part of the food chain, and they come in different sizes and types.
Consumers can be classified into several categories based on what they eat. For example:
Herbivores: These are animals that consume only plants for their food. Examples include rabbits, cows, and giraffes.Carnivores: These are animals that consume other animals for their food. Examples include lions, tigers, and sharks.Omnivores: These are animals that eat both plants and animals. Examples include humans, bears, and raccoons.Scavengers: These are animals that feed on the remains of dead organisms. Examples include vultures, hyenas, and some types of beetles.Consumers play an important role in an ecosystem, as they help to transfer energy and nutrients from one level of the food chain to another. They are an integral part of maintaining the balance and stability of an ecosystem.

Write 5-6 sentences that explains roles of Heredity and probability.
Answer:
Probability is a method for determining the likelihood of something uncertain occurring. If you flip a coin, you do not know whether it will be heads or tails, but probability can tell you that there is a 1/2 chance of either happening. Probability is a method used to predict the likelihoods of uncertain outcomes. It is important for the field of genetics because it is used to reveal traits that are hidden in the genome by dominant alleles. Probability allows scientists and doctors to calculate the chance that offspring will inherit certain traits, including some genetic diseases like cystic fibrosis and Huntington's disease.

Which statement about how geologists study the ages of rock layers is true?
The law of superposition means that older rocks are on top.
Geologists can find the exact age of a rock by looking at its relative position.
The principle of original horizontality provides the basis for the law of superposition.
Relative age can be determined by using the concept of unconformity.
Answer: The principle of original horizontality provides the basis for the law of superposition.
Explanation:
The law of superposition in geology suggests that the rocks or sediments which are newly formed due to erosion and sedimentation of the original rocks lie above the old material. This law is supported by the principle of original horizontality according to which the newly formed sediments suspend horizontally in the layers of rocks and sediments under the effect of gravity. Thus an horizontal strata distinguishes the old and the new material.

The herbivores in the forest don’t consume this low-growing invasive plant because they mistake it for a similarly shaped toxic plant in the forest. The invasive plant needs a lot of room to grow. It sprouts from its seeds much earlier than the native species. What effect can its growth have on the native herbivores’ food supply?
Answer:
It could grow at such an extrem erate that it could use up all natural resources that the native species needs to survive. thus breeding out all native species and becoming a invasive species. The native species the animals eat now does not exist and the animals that needed that food will decrease drastically in populus.
