An F1 cross between true breeding brown and white lines is set up. What evidence would best support white fur being dominant to brown -----
The best evidence to show that white fur being dominant is when all the offspring after the cross are white instead of brown
They are therefore expected to produce heterozygous lines.
The evidence that would best support white fur being dominant is when all the lines produced are white despite being heterozygous.
A dominant trait is known to mask the expression of other traits.

Which items are TRUE about minerals? Select the three correct answers. (2 points)
Observing one property is often the best way to identify minerals,
Rocks are the components that make up minerals.
Minerals can only be identified by their color and hardness.
Minerals are the components that make up rocks.
O Minerals are naturally occurring substances
Minerals are made of one element or one compound of elements
Answer:
The correct answers are 1) minerals are the components that make up rocks. 2) Minerals can only be identified that make up minerals. 3) Minerals are made of one element or one compound of elements.
Explanation:
I took the test. I got this question wrong but after submitting it, the lesson should me the correct answer.
The items that are true about minerals are:
Minerals are naturally occurring substances.Minerals are inorganic and homogeneous substances, which can be found on the surface of the Earth, formed in it naturally / spontaneously.
Minerals are made of one element or one compound of elements.Minerals are found in various forms in nature since they can be of a single element, such as gold, silver, copper, or a combination of elements, such is the case of some chemical compounds such as quartz, which is formed by silicon and oxygen.
Minerals are the components that make up rocks.A rock is a material that can be made up of a mineral or a combination of them, but its chemical composition is variable.
Therefore, we can conclude that a mineral is a substance produced by processes of inorganic nature which are made of one element or one compound of elements.

Birds lay eggs and are ectothermic while reptiles undergo internal fertilization and are endothermic.
Answer:
(A) Birds are endothermic and have four-chambered hearts, while reptiles are ectothermic and have three-chambered hearts.
Explanation:
got it right on the test
Birds and reptiles both belong to the animal kingdom. Reptiles are ectothermic and have three-chambered hearts, whereas birds are endothermic and have four-chambered hearts. Thus, option A is correct.
What are the characteristics of birds and reptiles?Birds and reptiles both belong to the kingdom Animalia and are chordates. They both have vertebral columns and the presence of the backbone. They share many similarities and differences in their physical appearances.
The birds are endothermic and can maintain constant body tempearture regardless of the external environment. While reptiles are ectothermic (cold-blooded) and regulate their temperature based on the external environment.
The birds have four-chambered hearts like mammals that separate the oxygenated from the de-oxygenated blood, whereas the reptiles have three-chambered hearts with one ventricle and two atria.
Therefore, the birds are endothermic, and reptiles are ectothermic.

Imagine for a moment that a large artery formed two branches carrying blood to two different organs. Branch 1 has a radius of 0.5 cm and Branch 2 has a radius of 1.0 cm. If the blood flow rate in Branch 1 is 2ml/min, what do you expect the blood flow rate of Branch 2 to be
The flow rate through Branch 2 is 8·√2 ml/min
Reasons:
Radius of Branch 1 = 0.5 cm
Radius of Branch 2 = 1.0 cm
Flow rate, Q = Velocity, V × Area, A
The area of the Branch 1 = π × 0.5² = 0.25·π
We have;
[tex]\dfrac{v_1^2}{r_1} = \dfrac{v_2^2}{r_2}[/tex]
Which gives;
[tex]v_2 = \mathbf{\sqrt{\dfrac{v_1^2}{r_1} \times r_2}}[/tex]
[tex]The \ velocity \ of \ Branch 1 , \ v_1 = \dfrac{2}{\pi \times 0.5^2} = \dfrac{8}{\pi}[/tex]
Therefore;
[tex]v_2 = \sqrt{\dfrac{\left(\dfrac{8}{\pi} \right) ^2}{0.5} \times1} = 8 \cdot\dfrac{\sqrt{2} }{\pi}[/tex]
[tex]The \ flow \ rate, \ Q_2 = 8 \cdot\dfrac{\sqrt{2} }{\pi} \times \pi \times 1^2 = 8 \times \sqrt{2}[/tex]
The flow rate through Branch 2 = 8·√2 ml/min

in the process of genetic profiling/dna fingerprinting, what is compared between two people/samples?
Answer:
"DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect." information from a website so reword it a bit and you should be ok.
In the process of genetic profiling/ data fingerprinting, genetic profiling is a process that can be compared between two people/samples.
What is genetic profiling?DNA profiling compares only the most variable sections of DNA, which has an advantage over whole genome sequencing when seeking to identify genetic changes between two individuals.
In the field of biology known as comparative genomics, genome sequences from various species—including humans, mice, and a broad variety of other organisms—from bacteria to chimpanzees are compared.
"DNA fingerprinting is a lab method used to connect biological evidence to a defendant in a criminal investigation. A DNA sample from a suspect is compared to one acquired from a crime scene. The evidence originated from that suspect if the two DNA profiles match.
Therefore, genetic profiling is compared between two people/samples.
