Why is oxygen more likely to form a polar covalent bond than other elements?
A Oxygen is slightly positive when it forms a covalent polar bond, which is its preferred electrochemical state.
B Oxygen has a high electronegativity and holds shared electrons more tightly than other atoms.
C Oxygen donates its electrons when forming covalent bonds, which are more easily breakable than ionic bonds.
>
D Oxygen has eight protons that strongly attract neutrons from small atoms such as hydrogen.
Oxygen is more likely to form a polar covalent bond than other elements because it tends to hold shared electrons more tightly than other atoms.
The polarity of covalent bonds depends on the magnitude of electronegativity difference atoms in the covalent bond. Recall that covalent bonds are formed by sharing of electrons between atoms.
Since oxygen is highly electronegative, it tends to hold shared electrons more tightly than other atoms. Hence, oxygen is more likely to form a polar covalent bond than other elements.

Which statement best explains how the needs of a unicellular organism are
met?
a) cell parts do everything
b) all cells must work together
c) most tissues work together
d) specialized cells work together
Answer:
a) cell parts do everything
Explanation:
Firstly, a unicellular organism is an organism with only one cell. This means that there would be no specialization or differentiation of cells. Also, this means that tissues, which Is the collection of similar cells, cannot be formed.
However, in its single cell, the unicellular organism will contain cell parts or organelles, which are organ-like structures that perform specific task in the cell. Therefore, cell parts in the single cell will do everything.

A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.
What is nucleotide?It is the sub units and buIlding blocks of DNA. It is made up of a five-sided sugar, phosphate group and then a nitrogen base.
These groups make the backbone of the DNA helix. If you look at a DNA helix, they make the side of the ladder or the side portion. They connect to a nitrogen base which make the steps of the ladder. The type of sugar that is used in a DNA helix is called deoxyribose.
Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.
Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine. Purines on the other hand make 5-sided and 6-sided rings.
Therefore, A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.

Look at the numbers used on the vertical axis. What
would happen to the bars on the graph if these numbers
were changed to 100, 150, 200, and 300?
Answer and Explanation: You will find the graph in the attached file
When changing the numbers in the vertical axis of the original graph, you will see that bars tend to get shorter than they originally were. This occurs because new numbers are much bigger than the original numbers, the proportion of the bars changes because they must represent the same information in a much bigger space. Offenlly, this is a tool very used by media to mark a tendency when informing something. So It is very important whenever looking at any graph to see what the axes are telling you because by the size of the bars you might infer something that might be different from what is really going on.

What is the ovum doing during the primary oocyte stage?
Answer:
Explanation:
The process of formation of Oocytes is called Oogenesis.It id the equivalent of spermatogenis in males.it begins in the ovaries where the oocytes divides to form oogoinia by mitosis.
The oogonia under grows growth,and These cells undergo further divisions by meiosis,but the meiotic division is restricted to Prophase 1 of meiosis.These diploid cells are called primary Oocytes,and all further division from this stage remains till puberty in girls.
Answer:
Generally in Prophase 1 of meiosis of any dividing cells the following activities occurs:
1 The nuclear envelope breakdown
2. Bivalent forms and Crossing over of chromatids occurs
3,the nucleoli disappears.
Since the ovum stops at Prophase 1 to form primary oocyte during Oogenesis,therefore these are what occurs in ovum at the primary oocyte stage.

mechanism is occuring?
A. Negative feedback
B. Positive feedback
Answer:
Positive Feedback
Explanation:
A positive feedback mechanism occurs in a contraction of uterus during childbirth.
What is a feedback mechanism?"It is a physiological regulation system in a living body that works to return the body to its normal internal state (or homeostasis)."It is of two types: positive feedback mechanism and negative feedback mechanism.In positive feedback mechanism: when activation of one component leads to the activation of another, it is known as positive feedback.
Example: During childbirth, the oxytocin level of a women into her first stage of labor is 40 pg/ml for uterine contraction, which activate more release of oxytocin for further contraction.In negative feedback mechanism: when activation of one component leads to the inactivation of another, it is known as negative feedback.
Example: when blood glucose level increase, the insulin are secreted which lowers the glucose level in blood.Hence, the correct option is: B. Positive feedback.
