What is matter?
~ Matter is something which all physical objects are believed to be made of -- it is a material substance that occupies space, possesses mass, and is made up mostly of atoms (basic unit of matter) which consists protons, neutrons, and electrons, that constitutes the observable universe.
The states of matter~ State of matter is the distinction or the difference in forms of matter we can observe in our daily life. The 5 states of matter thus far are; solid, liquid, gas, plasma, and bose-einstein condensate.
DifferencesMatters differ in characteristics, appearance and compositions. Written here are the basic differences in 3 most fundamental states of matter.
Solid - a matter which composed of rigid and closely packed particles -- particles move only via vibrations. Has definite shape and definite volume.
Liquid - particles can move back and forth, not too tightly packed -- has definite volume but with no definite shape.
Gas - the particles in gas are relatively far apart compared to solid and liquid, they're moving fast back and forth/side to side, and bouncing nonstop. Gas neither have definite shape nor volume, and is way compressible than solid and liquid.
2.2 If you are going to plant the following, which minerals/ nutrients will need to be modified and how? (Refer to theme 7 for requirements) (20) Eragrostis curvula, 3.2 Lolium multiflorum, 3.3. Cenchrus ciliaris. 3.4 Medicago sativa
Among the plant species mentioned, only the Medicago sativa species needs soil modification for its planting.
Eragrostis curvulaCultivated in full sun, but tolerates partial shade. Rustic, not developed in terms of soil, it adapts to poor, dry or humid soils.
Lolium multiflorumThis weed can occur at various times in wheat
Cenchrus ciliarisPlanting is usually carried out by seeds, being a manual in general. Sowing can be carried out in pots, furrows or by casting, when carried out in the rainy season.
Medicago sativaFlat areas marked by deep, fertile, well-drained soils, free of ponds and pH between 6.7 are the forage's preferred.

Are there any parts of the human body that get oxygen directly from the air and not from the blood?
Are there nuclear reactions going on in our bodies?
Can humans ever directly see a photon?
Answer:
A) Cornea in the eye
B) Yes, there are nuclear reactions constantly occurring in our bodies, but there are very few of them compared to the chemical reactions, and they do not affect our bodies much. All physical objects are made of molecules. A molecule is a series of atoms linked together by chemical (electromagnetic) bonds.
C) Photons are the only things that humans can directly see
Complete the statements by entering the appropriate term in the spaces below. Is the state of maintaining a stable internal environment despite changing external conditions.
Answer:
Homeostasis is the state of maintaining a stable internal environment despite changing external conditions.
Explanation:
Got it right on edge! Good luck <3
Homeostasis is defined as maintaining the internal environment without changing external conditions because the body can regulate its internal environment according to conditions.
What is homeostasis?As it is currently described, homeostasis is a self-regulating process through which biological systems retain stability while adapting to changing environments.
The maintaining of steady blood pressure in the human body by a series of tiny modifications in the normal range of operation of the hormonal, neuromuscular, and cardiovascular systems is an example of homeostasis.
Homeostasis ensures ideal conditions for enzyme functioning and all cell activities throughout the body. It is the preservation of a consistent internal environment in the face of changing internal and external situations.
Therefore to change the internal environment without external conditions, homeostasis is the major process.

In the embryo, the early skeletal muscle originates from the _______. In the adult, skeletal muscle is repaired by fusion of _______ with muscle fibers. Fill in the blanks.
The prenatal muscle originates from the myotome. The myotome produces presumed myoblasts that form the satellite cells. Answer: myotome / satellite cells.
How is the skeletal muscle originated and repaired?Myogenesis is the process of skeletal muscle formation during the embryonal stage. Structures derived from the mesodermal produce the firsts muscle fibers of the body, and then other additional fibers.
The myotome is a primitive muscular structure that contains progenitor muscle cells. Embryonary myotome cells produce two types of cells,
presumed myoblasts that constitute a store of cells that can multiplicate through mitosis
properly said myoblasts that can not suffer mitosis
Some of the presumed myoblasts can differentiate into other cells, and some others remain undifferentiated, turning into satellite cells.
This is, progenitor cells in the myotome originate presumed myoblasts, and then these last ones produce satellite cells located in the postnatal skeletal muscle.
Satellite cells are involved in the postnatal process of muscle repair. They suffer successive mitosis producing new myoblasts and more satellite cells.
In the embryo, the early skeletal muscle originates from the myotome. In the adult, skeletal muscle is repaired by fusion of _Satellite cells_ with muscle fibers.You can elarn more about the muscle formation and repair at

2. A hypothesis is an educated guess based upon observation. It is an explanation of a single event based upon what is observed. A hypothesis has not been proved but can be supported by experimentation.
a) Suppose that out of 10 trees planted in a yard, only five survived. What kind of hypothesis could you make about this observation or event? Remember that a hypothesis needs to have a certain format. (2 points)
b) How could you test this hypothesis? What type of experiment could you perform? (2 points)
c) How would this hypothesis be different from a scientific law? Review the definitions of law and hypothesis to help you. (2 points)
A law is backed by scientific evidence which is reproducible while a hypothesis is just a guess that may be confirmed or disproved by experiment.
What is a hypothesis?A hypothesis is a guess that is based on enormous background information. If only five trees survived, it is possible that they received more light than the other 5.
In that case, I will design an experiment in which the same kind of plant is randomly assigned to different treatment groups that receive varying degrees of light and the rate of growth of each group is compared.
