Answer:
those organisms that decompose the living organisms after death and change them into simpler substances are called decomposers. For example fungi, bacteria,etc. difference between herbivores and carnivore are
the animals that eat green plants are called herbivores but the animals that eat flesh of other animals are called carnivores.
examples of herbivores are cow,goat,etc but examples of carnivores are lion, tigers,etc.
Why does our body temperature increase sometimes when our body is attacked by a pathogen?
Answer:
Some pyrogens are produced by body tissue; many pathogens also produce pyrogens. When the hypothalamus detects them, it tells the body to generate and retain more heat, thus producing a fever.
Answer:
When your body temperature rises because of an infection, it's called a fever. Fevers are caused by chemicals called pyrogens flowing in the bloodstream. Pyrogens make their way to the hypothalamus in the brain, which is in charge of regulating body temperature. When pyrogens bind to certain receptors in the hypothalamus, body temperature rises.

What is the similarity between accuracy and Precision
Answer:
Accuracy and precision are alike only in the fact that they both refer to the quality of measurement, but they are very different indicators of measurement. Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value.

Immediately after an embryo forms, it begins to replicate new cells. What is the most likely type of cells that form during the first few divisions?
pluripotent cells
multipotent cells
totipotent cells
oligopotent cells
Answer:
Multiponent cells
Explanation:
Multiponent cells are most likely to form after the first few divisions, if u dont belive me check your lesson.
trust my answers if YOU want to.
The most likely type of cells that form during the first few divisions is referred to as the multipotent cells.
Multipotent cells have the ability to replicate and differentiate into more
than one type of cells.The differentiation brings about specialization of the
cells which involves a group of cells which are formed having similar
structures and being able to perform similar functions.
This ensures that the human cells have their unique structure and functions
thereby enabling them work together to achieve a common goal.

The insect that is the strongest singer in the animal kingdom
Answer:
hope this helps
Explanation:
Dr Fernando Montealegre-Z, from the School of Life Sciences, University of Lincoln, UK, said: "To call distant females, male katydids produce songs by 'stridulation' where one wing (the scraper) rubs against a row of 'teeth' on the other wing. The scraper is next to a vibrating drum that acts like a speaker. The forewings and drums are unusually reduced in size in the Supersonus species, yet they still manage to be highly ultrasonic and very loud."
The insect that is considered the strongest singer in the animal kingdom is actually the male cicada. Male cicadas produce loud and distinctive mating calls using specialized sound-producing organs called "tymbals" located on their abdomen.
Cicadas are known for their loud and persistent buzzing or chirping noises, which can reach up to 120 decibels. This is comparable to the noise level of a rock concert or a chainsaw. The high-pitched mating calls of some species of cicadas can be heard from great distances and are often described as a chorus. However, among insects, cicadas are certainly among the most notable for their impressive vocalizations.

Qué factores interviene en la manifestación de los genes? (pregunta de indagación)
Toma en cuenta el concepto de gen: El gen es la unidad física básica de la herencia. Los genes se transmiten de los padres a la descendencia y contienen la información necesaria para precisar sus rasgos. Es la unidad molecular de la herencia genética, pues almacena la información genética y permite transmitirla a la descendencia.
Ahora, planteamos nuestra HIPÓTESIS o respuesta probable a nuestra pregunta de indagación. Recordemos que tiene que tener las dos variables en relación de causa – efecto.
VARIABLE INDEPENDIENTE (CAUSA) VARIABLE DEPENDIENTE (EFECTO) INTERVINIENTES
En este caso, la hipótesis podría ser: los genes se manifiestan de acuerdo a mecanismos genéticos y ambientales. En este caso, las variables independientes (causas) podrían estar representadas por interacciones génicas e intergénicas tales como relación de dominancia completa o epistasis (factores genéticos) o bien cambios de temperatura (factores ambientales), los cuales inciden sobre la variable dependiente (grado de expresión génica) y cuyos efectos están representado por el fenotipo del individuo.
La hipótesis es una explicación plausible a un fenómeno observado en el mundo natural, la cual puede ser comprobada (o rechazada) mediante el uso del método científico.La variable independiente o 'causa' puede ser definida como la variable que produce un efecto sobre la variable dependiente, y que no cambia a lo largo del experimento.Por otra parte, una variable dependiente es una variable que cambia a lo largo del experimento de acuerdo a la variable independiente y que el investigador mide para determinar el efecto de la variable independiente.Aprende más sobre este tema en:

What is the atomic number, number of neutrons, and the mass for a neutral oxygen atom?
Answer:
Atomic Number: 8
Number of neutrons: 8
Mass of neutrons: 16 (AMU if you want the units)
Explanation:
The answer for both the number of neutrons and atomic number is on the top
The mass is at the bottom
Answer:
An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999. The atomic number tells you how many protons are in the atom's nucleus.

Student A has 64 grams of water in their water bottle. Student B has 1.3 kilograms of water in their water bottle. Student A has more water in
their water bottle.
O True
O False
Answer:
False
Explanation:
Water in student A's bottle = 64 grams
Water in student B's bottle = 1.3 kg = 1300 grams
1300 grams > 64 grams
So, Water in student B's bottle > Water in student A's bottle.
