which of these does NOT necessarily contribute to the sounds detected by the stethoscope as blood passes through the heart.
A) iron level is the blood
B) velocity of the blood during motion
C) viscosity of the blood as it moves through the heart
D) density of the blood as it is pumped through the heart
Answer:A. iron level of the blood
Explanation:
Answer:
A. iron level of the blood
Explanation:
All of the other properties are physical properties that can be detected by vibrations picked up by the stethoscope. The chemical property, iron level, will not necessarily be detected by the stethoscope but may contribute to poor cardiac health.
explain how environmental factors affect the rate of transpiration in flowering plants
Explanation:
there are a couple of environmental factors that affect the rate of transpiration. they include:
I) wind:in a windy environment there is easy movement of moisture hence it does not accumulate on the leaf surface. this helps to increase diffusion gradient between the intercellular spaces in the leaf and in the environment there4 the rate of transpiration is increased. in a calm environment moisture accumulates on the surface of a leaf there4 reducing the diffusion gradient there4 reducing the rate of transpiration
ii) atmospheric pressure :in low lands there is high atmospheric pressure than in the highlands. the more the atmospheric pressure the more the pressure exerted on the cells of the leaves there4 reducing the rate of transpiration.
iii) humidity:the more the humidity in the atmosphere the less the rate of transpiration. this is due to low diffusion gradient due to accumulation of water vapour on the surface of the leaf
iv) temperature:a rise in temp increases the water vapour holding capacity of air in the air spaces within the spongy mesophyll layer. the water vapor pressure in the intercellular spaces increases causing an increase in diffusion gradient between the intercellular spaces and the environment there4 increasing the rate of transpiration. decrease in temp decreases the water vapor holding capacity in the intercellular spaces there4 diffusion gradient is lowered there4 reducing the rate of transpiration.

a. Vestigial structures
b. Analogous structures
C. Homologous structures
d. Embryological structures
Answer:
Homologous structures
Explanation:
Its C
Similar features that originated in a shared ancestor are called Homologous structure. So, the correct option is C.
What is Homologous structure?Homologous structures are defined as structures that have a common basic structure but perform different functions. For example, the forelimbs of reptiles, amphibians and mammals all have a common ancestor but have been variously modified to perform different activities.
Homologous structures share a similar ancestor as they are modified to perform distinct tasks. Like in the above given example, the legs of a crocodile and a mouse have similar bone structure and develop in a similar way.
Thus, similar features that originated in a shared ancestor are called Homologous structure. So, the correct option is C.

Gregor Mendel's research consisted of using parent pea plants that were pure breeds. What genotype(s) would be considered pure breeds? (use the letter "B" and/or "b" in your genotype) *
Answer:
The genotypes thatwould be considered pure breeds are BB and bb
Explanation:
The genotype of an organism refers to an organism's complete set of genetic material or genes.
Genes are units of DNA that carries information for a particular physical or functional trait or character in an organism. Some genes act as instructions to make proteins while some genes do not code for proteins. The proteins made by a gene expresses the traits and characters of that organisms. Genes for a particular trait may have one or more variants known as alleles.
In Gregor Mendel's research using pea plants, flower colour in a pea plant had two different alleles; one for red flower colour and one for white flower colour. If a plant had the same allele for flower colour, the plant was considered a pure breed.
For example, given B was the allele for red flower colour and b was the allele for white flower colour, a plant having the two alleles for white flower colour bb, is a pure breed. Similarly, a plant having the two alleles for red flower colour, BB is a true breed.

Answer:
Ice, Water and Water Vapor
Answer:
I do not see answer choices but I will try my best to explain.
Explanation:
Solid, means a shape. Solids are hard and generally keep their shape relative to heat. Some solids, like ice, can be cold, others can be hot.
Liquid means it fits in a container but can roam freely. Think of water in a pool but if the pool breaks it flows anywhere. This can be hot or cold.
Gasses has no limit. Its everywhere and cannot be contained in one single place because of how much the particles move. Think of water vapor for this one, it can be hot or cold.

What generally occurs at the time of DNA replication?Errors occurs mainly at the time of DNA replication. Mutations has been refers to the changes in the DNA sequence made at the time of DNA replication, thus, the DNA replication procedure has possesses characteristics that has minimize mutations.
The three small scale of the mutations, which can take place at the time of the DNA replication which are nucleotide substiution, inversion as well as translocation.
Eukaryotic chromosomes have often multiple origins of replication. Given the size of the eukaryotic chromosomes, this has been necessary for full reproduction to occur on time. Each of these origins defines the replica, or DNA sequence, that reproduces from a particular origin. The copies do not reproduce at the same time, so care must be taken to ensure that the copies are used only once during the cell cycle.
