Answer:
Monocots differ from dicots in four distinct structural features: leaves, stems, roots and flowers. ... Whereas monocots have one cotyledon (vein), dicots have two. This small difference at the very start of the plant's life cycle leads each plant to develop vast differences.

What is prokaryotic cells??
Answer:
Prokaryotes are single-celled organisms of the domains Bacteria and Archaea. All prokaryotes have plasma membranes, cytoplasm, ribosomes, a cell wall, DNA, and lack membrane-bound organelles. Many also have polysaccharide capsules. Prokaryotic cells range in diameter from 0.1–5.0 µm.

When a genotype of a guinea pig is "Hh" (select all that are true)
One chromosome of the homologous pair has a sequence that results in hair and one chromosome has a sequence that results in no hair
One copy of the "H" allele on the homologous chromosome is enough to make the guinea pig have hair since both alleles are transcribed and translated
Only one of the chromosomes in the homologous pair carry the genetic sequence to make hair
Both chromosomes in the homologous pair carry the genetic sequence to make hair
Answer:
One chromosome of the homologous pair has a sequence that results in hair and one chromosome has a sequence that results in no hair
One copy of the "H" allele on the homologous chromosome is enough to make the guinea pig have hair since both alleles are transcribed and translated
Only one of the chromosomes in the homologous pair carry the genetic sequence to make hair
Explanation:
Hairy is dominant over hairless. If there was a hairless guinea pig here instead, we would know its genotype. It would be hh. Remember any time a dominant allele is present it is expressed in the phenotype, so if the phenotype is not the dominant one, we know the genotype must contain two recessive alleles.
These are the factors that is true, When a genotype of a guinea pig is "Hh"
• One chromosome of the homologous pair has a sequence that results in hair and one chromosome has a sequence that results in no hair
• One copy of the "H" allele on the homologous chromosome is enough to make the guinea pig have hair since both alleles are transcribed and translated
• Only one of the chromosomes in the homologous pair carry the genetic sequence to make hair

Comparing the four most common types of power plants in Alberta (coal, natural
gas, wind, and hydroelectric), which has the lowest efficiency in electricity
generation? and why?
Answer:
Coal.
Explanation:
Steam power plant has the lowest efficiency in electricity production which can only be run with the use of fossil fuels such as coal. The efficiency of this power plant is the lowest because large amount of coal is converted into smoke and other gases and very less amount of coal into heat energy. This coal is used to produce heat energy which can be used in the heating of water to produce steam. This steam is used to move turbines which turn mechanical energy into electric energy.
There are 7 climatic zones on Earth; Equatorial, subequatorial, tropical, subtropical, temperate, subarctic, and subarctic, Arctic, and Antarctic.
Answer:
False
Explanation:
Is it true or false
Solution
The seven climatic zones of earth are -
a) Tropical climates
b) Dry Climates
c) Moist Subtropical Mid-Latitude Climates
d) Moist Continental Mid-Latitude Climates
e) Polar Climates
f) Highlands
g) Temperate
Hence, the statement is false
Why is carbon so important for living things
Answer:
Organic compounds make up the cells and other structures of organisms and carry out life processes. Carbon is the main element in organic compounds, so carbon is essential to life on Earth. Without carbon, life as we know it could not exist.
Explanation:
Answer:
Carbon is the most important element to living things because it can form many different kinds of bonds and form essential compounds.

How does bacteria cause disease?
Answer:
Bacteria cause disease by secreting or excreting toxins (as in botulism), by producing toxins internally, which are released when the bacteria disintegrate (as in typhoid), or by inducing sensitivity to their antigenic properties (as in tuberculosis).

Adults produce gametes through a type of cellular reproduction called mitosis. The process of a sperm cell and an egg cell fusing together is called fertilizationand produces a zygote. As a zygote undergoes rapid cell division to develop into an embryo, fetus, and eventually baby, the type of cellular reproduction being used is . As a baby grows into an adult, the type of cellular reproduction used is mitosis.
Answer:
Mitosis.
Explanation:
Mitosis is the type of cellular reproduction which is used in order to develop an embryo, fetus, and eventually baby. In mitosis type of cell division, the parent and mature cells divides into two daughter cell. This type of cell division occurs in somatic or body cells whereas meiosis type of cell division occurs in the sex cells which produces four daughter cells from a single parent cell.
