D. another word for high blood pressure
Answers
Atherosclerosis refers to the build-up of fats and cholesterol in the walls of blood vessels (Option A).
What is atherosclerosis?Atherosclerosis is a disease characterized by the build-up of fats and cholesterol in the walls of blood vessels.
This build-up of fats narrows the blood vessels, thereby difficulting the movement of blood in the bloodstream.
The symptoms of atherosclerosis include, among others, chest pain, shortness of breath and fatigue.

why is ice at 273 k more effective in cooling than water at the same temperature?
Answers
Answer:
it does not have any hidden heat.
Explanation:
Ice at 273K or 0°C is more efficient in cooling as it does not have any hidden heat. Water at the same temperature has hidden heat, banned latent heat of fusion, which is used to convert water into ice. Thus, ice at 273 K is more effective in cooling
hey could i have brainlesit answer thanks i worked hard :)
Ice at 273K is more effective in cooling than water at the same temperature as ice absorbs more heat to overcome the latent heat of fusion, as a result, provides the cooling effect.
What is latent heat?
Latent heat of fusion is the energy that must be provided to the solid matter so that there is a change triggered in the physical state of the matter, and as a result, leads to the formation of the liquid.
Ice at 273 K has a cooling effect as there is no hidden heat and latent heat, unlike the water that has hidden heat that makes them less cool than the ice at the same temperature.
Therefore, the ice exhibits a cooling effect at 273 K.

Why is it difficult to male level 4 organs in a lab?
Answers
Answer:
By providing an example using one organ for each of the four levels of complexity, we have the following:First level organ: Skin; this is because it takes up a few cells. Second level organ: Windpipes; this is because they have more complex shapes with multiple cells. Third level organ: Stomach; this is because the stomach has to act on demand instead of a flow. Fourth level organ; Heart. The reason it is difficult to make level four organs in a lab is that it has a complicated architecture with several cells, blood vessels and tiny capillaries included. So far, scientists are yet to fully develop solutions for the level four organs and hence, difficult to create in a lab.

In an example of pleiotropic genes, the flower color gene studied by Mendel affected ________ trait(s).
Answers
Answer:
two traits ,
Explanation:
In an example of pleiotropic genes, the flower color gene studied by Mendel affected a single trait.
Pleiotropy refers to a phenomenon where a single gene influences multiple, seemingly unrelated traits or characteristics in an organism. However, in this specific case of Mendel's flower color gene, it affected only one trait, which is the color of the flower.
Genes are the basic factors of inheritance. They are found in the DNA of all living organisms. They are responsible for transmitting genetic information from one generation to the next and play a crucial role in determining an organism's traits and characteristics.

Assuming that the population was in hardy-weinberg equilibrium for the g locus, what percentage of moths in the natural population was white in 1962 ?.
Answers
The percentage of moths in the natural population that was white in 1962 is : 4%
What is Hardy-weinberg equilibrium ?Hardy-weinberg equilibrium states that the sum total of all the genes of an individual in a population is constant when the disturbing factors such as genetic drift does not occur
p² + q² + 2pq = 1
Determine the percentage of moths in 1962Applying the equation below
p² + q² + 2pq = 1
p = frequency of dominant allele
q = frequency of recessive allele
q² = frequency of h0m0zygous recessive genotype
p² = frequency of h0m0zygous dominant genotype
From the graph
Frequency of G allele ( i.e p ) = 0.8
percentage of white moths = q²
Note : p + q = 1 ---- ( 1 )
Insert value into equation ( 1 )
0.8 + q = 1
therefore ; q = 0.2
Hence the percentage of white moths = ( 0.2 )² = 0.04
= 4%
Hence we can conclude that The percentage of moths in the natural population that was white in 1962 is : 4%
