Answer:
Phenotypic ratio= 1:1
Genotypic ratio = 1:1
Explanation:
This is a monohybrid cross involving a single gene that specifies a color phenotype.
According to the question, WW, which is homozygous dominant i.e same allele is white while ww, which is homozygous recessive is black.
Hence a genotype Ww will possess a white phenotype since the W allele will mask the expression of w.
In a cross between a female and male with a a Genotype Ww and ww respectively. The parents alleles will be separated into gametes according to Mendel's law of segregation. (See attached image).
Ww will produce gametes W and w
ww will produce gametes w and w
The four possible offsprings will have Ww (2) and ww (2) genotypes. Hence two of them will be white while two will be black.
Hence, the phenotypic ratio will be 1:1 while the genotypic ratio will also be 1 Ww: 1 ww
Answer:
Which of the following pairs of terms is mismatched?
D. bacteriostatic – kills vegetative bacterial cells
Explanation:
All the options mentioned are different methods of antimicrobial control. Germicide is a product that kills microbes, a sterilant destroys all living microorganisms, fungicide kills yeasts and molds and virucide inactivates viruses. When it comes to a<em> bacteriostatic agent not necessarily kills bacteria, but it stops them from reproducing. </em>To take into account, the best method to sterilize heat-labile solutions is membrane filtration.
The enzyme is lipoxygenase.
Lipoxygenase is a variety of enzymes that can cause oxidation of fatty acids. There are several varieties of lipoxygenases, some of which are present in plants. They are involved in the formation of white blood cells that are involved in some severe allergic reactions (anaphylaxis). <em>It is based on this knowledge that antiallergic drugs have been developed to inhibit the activity of lipoxygenase, including reducing inflammatory reactions.</em>
Leukotrien are named thus because they were discovered in leucocytes and that they are unsaturated lipids with 3 conjugated double bonds (trienes) and 20 carbon atoms
Composite volcano erupts with massive cloud of smoke and ash towering above a large volcano with steep sides.
Explanation:
A volcanic terrain composed of slowly accumulated lava erupts out to the earth’s surface through vents or openings. Depending upon the type of vent and the flow of lava, volcanoes are classified into four basic types – Cinder cone, Composite, Shield, and Lava dome volcanoes.
A Composite volcano, also called Stratovolcano, arise from grandest large mountains. These mountains usually are tall with sides being even but steep.
These mountains are built by several layers of a repeated lava flow, cinders, volcanic ash, blocks and other volcanic material.
Due to these volcanoes arising from tall mountains, these can erupt and rise to great height to even above 8,000 feet from their surroundings.
Most of the tall mountains of the world like Mt. Rainier, Mt. Hood, Mt. Shasta, Mt. St. Helen in the USA, Mt. Cotopaxi in Ecuador, and Mt. Fuji in Japan are all composite volcanoes
