Water has special characteristics because liquid water is denser than ice and ice floats on top of liquid water.
Answer: Option A & D
<u>Explanation:</u>
A water molecule is formed by the covalent bonding between two atoms of Hydrogen atom with one atom of Oxygen. In water, the Hydrogen bonds are the one that keeps the water molecule intact.
When the water molecule freezes the bonding becomes weak as they are separated and set apart which makes the liquid water denser than ice. Normally a substance floats if it is less dense. Ice floats because it is less dense than water.
The scientific method's foundation is best described as "the process of hypothesis and testing through which scientific inquiry happens." Thus, the correct option is D.

What is scientific method?</h3>
The scientific method is a set of actions that are followed in order to develop scientific knowledge.
The scientific process includes the following steps:
- To make observations on a particular natural occurrence and then generate questions based on those observations.
- To answer these questions, you must propose a credible explanation (i.e., a hypothesis).
- To put the working hypothesis to the test using experimental and/or observational methods.
- To gather information in order to confirm or refute a working theory.
- Analyze the findings and develop conclusions.

Answer:
a. 100% of the offspring will have the Bb genotype
Explanation:
In a BB x bb cross, the one with BB genotype produces B gamete, while the other only produces b gamete.
Therefore, the zygote in this cross has Bb genotype.
Tissue Pain receptors that are sensitive to tissue damage or distortion of tissue.
Answer:
I. Cell capsule
II. Cell wall
III. Plasma membrane
IV. Nucleoid
V. Cytoplasm
Explanation:
In the structure of bacterium, I represent Cell capsule which is the outer covering of bacterium cell, II is the Cell wall that is located after the cell capsule. III is the Plasma membrane which is also called cell membrane which is the second boundary of cell. IV represents Nucleoid which like nucleus having genetic material, V is Cytoplasm that is responsible for the transportation medium for various nutrients..
