What is inherited trait ?Inheritance is defined as the transfer of genetic information from parents to their offspring.
The transferred characters or traits include eye color, hair color, and blood type.
Trait can be defined as the genetic character which can be transmitted by the parent to its offspring during fertilization.
The trait which is expressed phenotypically is called as dominant trait while the other trait which is not expressed called as recessive trait.
These variations are observed in the species due to survival benefits or genetic drift.
Acquired traits are acquired by an individual in his lifetime which is due to their own activities or external influence.
Like inherited traits, acquired traits are unable tp pass to the next generation like ability to dance, cook.
Thus option A is correct.

Doing this could damage their environment.
a ) Suggest one immediate problem for the animals that live on the hill.
b ) Suggest one problem that could arise during the rainy season.
Answer:
1) Deforestation has real consequences for animals. The most serious impacts of deforestation on animals are listed below. #1 Habitat loss Deforestation can lead to a direct loss of wildlife habitat as well as a general degradation of their habitat.
2)When there is less soil stability because of the disadvantage of erosion, the risk of a flooding event occurring during the rainy season increases dramatically. Poor water absorption levels make it easier for higher accumulation levels since the trees are no longer present to take up the extra moisture.

Explanation:
In thermoplastics, the arrangement of monomeric units is linear and in thermosetting plastics, it is cross-linked. Thermoplastics are usually soft, weak and less brittle, so can get soften on heating and stiffen on cooling. They can be melted, remoulded and recycled easily.

What are muscle cells?A muscle cell exists also known as a myocyte when directed to either a cardiac muscle cell or a smooth muscle cell as these exist both small cells. A skeletal muscle cell exists long and threadlike with many nuclei and is named a muscle fiber. Muscle cells originate from embryonic precursor cells named myoblasts.
The muscle cells exist as a specialized kind of cell (one of the four tissues) that can contract to exert action.
These cells (muscle cells) can be paralyzed by utilizing various inhibitors of movement such as poisons.

difference between diabetes mellitus and diuresis?? please help
Explanation:
If you have been in EMS long enough, you may well have encountered a patient with diabetes insipidus. Like many, you may have assumed that it is a variant of the common disease diabetes mellitus. Actually, diabetes mellitus and diabetes insipidus are totally unrelated other than the name. The term diabetes is derived from Latin (originally Greek) and means “to go through or siphon,” referring to a large amount of urine produced by the kidneys. The term melitus, in Latin, means “sweet.”
Why is The sun is the ultimate source of energy
for all living organisms.'
Answer:
"Sun is the ultimate energy source for all living organisms."
✴This is because plants need sunlight to make food through photosynthesis. This food is consumed by the animals and human-beings. Carnivores indirectly depend on plants for their food. So, if Sun is not there there will be no life on earth.
✴Secondly, sunlight is a good source of Vitamin-D.
Vitamin D is essential for strong bones, because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been associated with rickets, a disease in which the bone tissue doesn't properly mineralize, leading to soft bones and skeletal deformities. So if sunlight is not there it can result in loss of Vitamin-D which can cause deficiency diseases.
✴If sunlight is not there there will be no day on Earth. Light will not reach our Earth. Every time there will be only darkness.

In water and ice, the slightly ______ hydrogen atoms in one water molecule are drawn to the slightly _______ oxygen atom in another water molecule.
A. positive, negative
B. negative, positive
C. neutral, positive
D. neutral, negative
Answer:
option c
Explanation:
The water molecule is a polar substance that has partially charged ions. The hydrogen atom is partially positive, whereas the oxygen atom is partially negative in charge. Thus, option A is correct.
What is polarity?The polarity of the molecule is defined by the presence of the electrical charges over the elemental atom that results in the formation of the chemical bonds by the electrostatic forces.
Water is an example of a polar molecule that is linked by a covalent bond by sharing the electrons between the oxygen and the hydrogen atom of the molecule.
The hydrogen atom is said to have a partial positive charge and oxygen has a partial negative charge because of the uneven electron density. The electronegative oxygen pulls the hydrogen towards it.
Therefore, option A. hydrogen is partially positive and oxygen is partially negative.

Monosaccharides, fatty acids, nucleotides and amino acids are all monomers used to build macromolecules. Monosaccharides are the building blocks to which macromolecule?
DNA
Carbohydrates
Proteins
Lipids
Answer:
Carbohydrates
Explanation:
Fatty acids are building blocks of lipids
Nucleotides are building blocks of DNA
Amino acids are building blocks of protiens
Monosaccharides are building blocks of carbs
Monosaccharides are the building blocks to carbohydrates. The correct option is B.
The constituent parts of monosaccharides are what make up carbs. Carbon, hydrogen, and oxygen make up the macromolecules known as carbohydrates in the ratio of 1:2:1.
Simple sugars like glucose and fructose are monosaccharides, which can combine through dehydration synthesis to create bigger carbohydrate molecules.
In addition to serving as an essential source of energy for living things, carbohydrates also function as structural support for things like plant cell walls and as energy storage in the form of starch and glycogen, respectively.
To create complex carbohydrates like disaccharides (like sucrose) and polysaccharides (like starch and cellulose), the monosaccharides combine through glycosidic linkages.
Thus, the correct option is B.

H20fall, how do I find out how much salt is in my pool?
A very peculiar question, kind sir
I supposed one can start by allowing his pool water to evaporate in the blazing summer heat in order to separate the solute (salt) from the solvent (water). After the separation, the obtained mass of salt can be measured on a scale in order to determine the concentration of salt that is present within thy swimming pool. This technique is the most classic of all, and is also the most expedient way to extract salt from water.

Answer:
centimeter
Explanation:
Description:
used to measure lengthsmaller than a meterAll answer choices are units that are used to measure length so the first hint isn't much help.
The only unit listed that is smaller than a meter is a centimeter so the answer would be centimeter.
1 Centimeter = 0.01 Meter
( If it helps to remember centi means one hundredth, so centimeter means one hundredth of a meter )
centimeter is the lowest standard unit of measure the length.
What Is standard unit of measurement of length?The product of speed and time can be represented as distance.
d=s×t, where d is the distance m, t is the time taken to cover s
s is the speed in m.s-1
Different units can be used to measure Length like centimeters, inches, meters, it can be classified into two types such as Standard units of measuring length and non-standard units of measuring length.
Standard Units of Measuring Length include the pre-defined such as If two measure the length of the same object using any standard unit will get the same result.
standard units of length are measured in the form of meters, centimeters, inches, feet. It can be up two types such as Imperial units and metric system units.
Imperial System is based on existing units, examples are nautical mile, mile, rod, inch etc.
Metric units are kilometer, hectometer, decameter, meter, centimeter, and millimeter etc.
