Plasma membrane of the cell functions to recognize other cells. Thus option D is correct.
What is Plasma membrane?The plasma membrane which is an outer covering of cell present in both prokaryotic and eukaryotic cell.
It is a thin selectively semi-permeable membrane which enclose the cytoplasm along with other organelle.
Proteins and lipids are the major components of membrane, beside this carbohydrate are also present in cell membrane.
The most common lipid in membrane is phospholipid, other lipids are glycolipid, sphingolipid.
The function of cell membrane is to provide protection and maintain the integrity of the internal environment of the cell,
It act as a base of attachment for the cytoskeleton for cell-cell communication.
It involve in transport of materials like nutrients, toxic substances.
Thus option D is correct.

Mutations in which of the following cells would get passed on to the next generation?
I. sperm
II. Skin cell
III. Egg
IV. Neuron
A. II, III, and IV
B. III only
C.I and III
D. I, III, and IV
Answers
Answer:
C. I and III
Explanation:
A mutation needs to occur in a gamete cell in order to be passed down to the next generation.
If it occurs in a somatic (body) cell, the mutation will only be present in that organism.
On the other hand, in a gamete cell, the mutation will pass down because gamete cells are directly involved in the genetic makeup of the offspring.
So, since sperm and egg cells are gametes, mutations in those cells would get passed on.
The correct answer is C. I and III

What are the properties of a compound ?A compound composed up of two or more elements which are chemically combined with a fixed proportion by their mass.
For example, Water, Sodium Chloride, Ammonium Chloride etc.
They have fixed melting and boiling points.
Formation of compound is a change in chemical reaction and the components of compound are mixed in a fixed proportion.
Two major types of compounds are covalent and ionic compounds.
Covalent compounds refers to formation of covalent bond among two nonmetals, like water or methane. These molecules are neutral and weak.
When metal react with non metal it form Ionic compounds, are held together by opposite charges, so the bond is stronger than covalent compound.

Explain what, if any, is the issue facing DNA polymerase in regards to its 5’->3’ activity when replicating DNA.
Answers
Answer:
The two strands of DNA are replicated in different ways
Explanation:
DNA replication is a process that occurs during the S phase of the cell cycle that consists of making two identical copies of the double-stranded DNA molecule, which subsequently are distributed in the daughter cells during cell division. During this process, DNA polymerase can add nucleotides in 5' to 3' direction, but not in 3' to 5' direction. In consequence, the DNA strand that has 3’ to 5’ directionality can be synthesized directly, while the DNA template strand that has 5’ to 3’ directionality can't be synthesized in a continuous manner and thereby it is created by adding small DNA fragments, which are known as Okazaki fragments (150-200 nucleotides in size).

2. Calculate the rate of population increase for the whales and the seals from the data in table 2, trial 1. What does this rate represent?
Hint: From the point of zero change on the graph to the highest population achieved is a change in time of 100 months. (Refer to the science skills practice in the lesson for the correct formula for the rate of population change.)
Answers
Answer:
There are no tables but it should be a bell curve. as a population of whales rise the population of seals will decrease, eventually creating a plateau in the whale population. shortly after the plateau in the whale population the whale population will begin to decline ( as food becomes less available) causing the seal population will begin to rise and restabilize. this pattern should continue cyclically creating a wave function on a graph!

Describe the intermolecular interaction of the surface carboxylate groups of a micelle and the surrounding water.
Answers
Answer:
Hydrophilic portions are outside and hydrophobic regions are inside
Explanation:
A micelle is an assembly of amphiphilic molecules formed in a liquid solution, generally an aqueous solution. Micelles are formed due to the packing (aggregation-like) behavior in which single-tail lipids are organized in a bilayer. A typical micelle in aqueous solution forms a spheric assembly where carboxylate ions are organized in a mode that hydrophilic head regions enter in contact with the surrounding water, while hydrophobic (lipophilic) portions are disposed inside the micelle.

Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.

If a mother is affected by an X-linked dominant condition and the father is not, which children can inherit the condition?
only males
neither males nor females
both males and females
only females
Answers
Answer:
both males and females
Explanation:
The sex chromosomes in male and female humans are X and Y chromosomes. X-linked traits are those traits which are associated with the X- chromosome.
According to the question, the trait is passed on a X-linked dominant condition, which means that the possession or not of the condition is dependent on the presence of the dominant X-chromosome. The dominant X-chromosome will always express itself even when in an heterozygous state with a normal X-chromosome i.e Xx. Hence, only a individual recessive for the X-chromosome will be normal.
A mother that is affected by the X-dominant condition will either possess a; XX or Xx genotype while a father that is normal (not affected) will possess a (xY) genotype. Since the mother passes one of her X chromosomes to her sons and the other to her daughters, both male and female children will be affected by the condition.
N.B: If the mother is heterozygous for the affected X-chromosome (Xx), half of her sons and half of her daughters will inherit the condition but if the mother contains two dominant X-chromosomes (XX), all of her sons and daughters will inherit the condition.

d) passing a green tax to make homeowners pay for their pollution.
e) providing asthma inhalers to children under the age of 12 years.
Answers
Answer:
preparing meals using solar cookers.
Explanation:
solar cookers radiates at low rates.Therefore the most of the nutrients in the foods are conserved.Thus most micro nutrients for biochemical activities are retained. Vitamins which can not withstand high temperature are preserved.
Most importantly carcinogens which are usually associated with high heat foods are avoided ,when cook with low heat of solar cookers
The solar cooker is smoke free,therefore irritation of the lungs,lung cancer associated with high heat cookers is avoided.
Specifically,local Mayan women exposed to high heat smoke cookers, suffers lung cancer,and those with pregnancy gives to infants with low birth weights. Children exposed to theses high heat also experienced acute lower respiratory infections.
Thus the smokeless,low heat solar cooker is safer.
