Middle School Biology Questions, Questions About Junior High School Biology

Reflection Reflection arc.

Iron (they say it's oxygen, I don't think it's right!) Isn't there usually iron deficiency anemia?

The periosteal is the cochlea.

White blood cells (platelets) (this one is not big.) I forgot about it in junior high school, hehe, biology is very interesting, I have to study hard

Reflex Reflex arc Oxygen (absolutely oxygen) tympanic membrane Cochlea Leukocytes Platelets.

Contemptible people take the high school entrance examination this year.

and a year of training in biology competitions.

...Unfortunately, the ls are not quite correct, uh.

1 Reflection Reflection arc.

2 Fe ions (see the title, there is a mention of red uh) 3 tympanic membrane cochlea.

4 White blood cells (in fact, they should be macrophages, but since they are junior high school level, there is no need to divide them too thinly) Platelets.

Hope it helps.

Reflection; Neuron; Iron; Eardrum; Acoustic neuroma; White blood cell; Platelet.

I'll listen to it next time

Reflexes: Neurons (nerve cells), iron, tympanic membrane, cochlea, white blood cells, platelets.

Reflexes, reflex arcs, iron, tympanic membranes, cochlea, white blood cells, platelets.

I'm over the college entrance examination, listen to my !!

Although I am the representative of the geography class, I still know a little bit about biology! Listen, brother, in order.

Reflex Neurons (I can't figure it out, half of the possibilities) Blood cells Tympanic membrane Cochlea White blood cells Platelets That's it, at most two wrong, rest assured! Good luck!!

1. The theory of nature holds that the vast majority of living things have it.

Overbreeding. i.e., organisms are capable of producing a large number of offspring, and among these offspring are a small number of individuals who survive. The reasons for the survival of this mass reproduction in small quantities are:

In nature, there is a very limited amount of food and space that living things can live in. For any creature to survive, it has to compete for enough food and space.

Struggle for survival. It is.

Biological evolution. of power. The struggle for survival includes: (1) the struggle between living beings and natural conditions; (2) the struggle between heterogeneous individuals; (3) competition among heterogeneous individuals; (4) Competition between individuals of the same species.

Chemical evolution.

It is advocated to study the law of change in the motion of matter.

The origin of life.

Think in. Primordial Earth.

under the condition of inorganics.

Can be transformed into organic matter, and organic matter can be developed into:

Biomacromolecules.

And. multimolecular system, until finally the emergence of primitive lifeforms.

Spontaneous generation.

also became autopoietic,'

Carrion. Raw maggots, rot.

Lignify. Cicadas' is.

Spontaneous generation is the theory that everything is naturally generated.
