Which two atoms form a covalent bond?
A. A sodium and chlorine atom
B. Two oxygen atoms
C. Two sodium atoms
D. An iron and oxygen atom​

Answers

Answer 1

in a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.

Discuss the interconnections of the cardiovascular system with each of the other major body systems introduced. Give specific examples of these interactions and explain their effect on homeostatic balance.

Answers

The correct answer to this open question is the following.

The interconnections of the cardiovascular system with each of the other major body systems is of the utmost importance for the health of the human body. The circulatory system's main function is to take blood to all the cells of our body. The instant the heart stops bombing blood to all the cells, organs, glands, and systems, the body stops its vital functions. The Circulatory system has a direct relation to the optimal operation of other systems such as the Respiratory system, the Reproductive system, the Digestive system, the Skeletal system, the Muscular system, the Lymphatic system, the Nervous system, and the Endocrine system.

a student placed a stack of rocks on a ramp. she added clumps of soil rooted with live grass. using a garden hose, she then applied a steady spray of water that soaked into the soil, making it heavier. what does the students experiment model

Answers

Answer: its C

Explanation:

Since a steady spray of water soaked into the soil, making it heavier. This student's experiment models: C. The role of rainfall in mass wasting.

A rock can be defined as a solid naturally occurring landform and it is typically made up of various minerals.

In this experiment, a stack of rocks was placed on a ramp and clumps of soil rooted with live grass were added. By using a garden hose, the student then applied a steady spray of water which soaked into the soil and made it heavier in weight.

Hence, this experiment models the role rainfall (steady spray of water) plays in mass wasting.

Mass wasting is also referred to as mass movement or slope movement and it can be defined as a geomorphic process through which rock, debris, soil, and regolith are largely moved downward, especially due to the force of gravity.

Basically, mass wasting describes the downslope (downhill) movement of rock and soil due to a steep slope and force of gravity.

In conclusion, the steady spray of water acts as a force which moves some of the soil constituents downward, making it heavier.

(c) find the longest interval during which no tree-cutting samples occurred. what is the first year that no tree-cutting samples occurred in that interval?

Answers

Answer:

Longest interval during which no tree-cutting sample occurred: 9 years (1203 AD - 1212 AD)

First year in that interval: 1203 AD

Explanation:

Lets complete the question first.

Q) A study uses tree rings to determine the year in which a tree was cut. The data is shown in the leaf and stem diagram in the ATTACHMENT.

The three digits number in the left column represents centuries and decades AD. The numbers on the right represents the years.

For example, consider the first input in the diagram

119 | 5   6

which means it represents 2 samples.

1195 AD, 1196 AD.

The longest interval with no tree-cutting samples is found from 1203 AD to 1212 AD.
