At school we are taught that there is a dominant gene for brown eyes and a recessive one for blue.
In this sentence, dominant means:
A. having undergone mutation
B. of or relating to single-cell organisms
C. having reached full development, growth, or
maturity
D. producing a trait even when inherited from only
one parent
Answer:
D. Producing a trait even when inherited from only one parent
Explanation:
A dominant gene, or a dominant version of a gene, is a particular variant of a gene, which for a variety of reasons, expresses itself more strongly all by itself than any other version of the gene which the person is carrying, and, in this case, the recessive.
What happens to the genetic material before the cell divides
Because each chromosome is made from a single molecule of 'DNA', before a cell divides itself, it had to replicate and copy its DNA. This makes it so that after cell division, each new cell holds an exact copy of the genetic material from the original cell.

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

Leaves are modified as tendrils for climbing as in
a) Cactus
b) Pea
c)Citrus
d)Bougainvillea
Answer: pea
Explanation:
In the garden pea, it is only the terminal leaflets that are modified to become tendrils. In other plants such as the yellow vetch (Lathyrus aphaca), the whole leaf is modified to become tendrils while the stipules become enlarged and carry out photosynthesis.

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.

Two brothers have thick hair that grows over their faces and most of their bodies.
This human disorder, called Ambra's Syndrome, shows X-linked dominant inheritance. The
mother of the boys is also affected by Ambra's Syndrome, although her excessive hair growth
occurs in various, scattered patches on her skin rather than a continuous coverage like her sons.
What is the most likely explanation for the patchy expression of hairlessness on the mother's
skin?
The most likely explanation for the irregular expression of hairlessness on the mother's skin is codominance
Codominance is a biological term to refer to the hereditary pattern that is characterized by:
In the heterozygous state, there is no recessive allele, but both behave as dominant. Codominance is characterized by the manifestation of both characteristics as dominant, without mixing.According to the above, the irregular expression of the lack of hair in the mother is a manifestation of the codominance of the hair gene and the hairless gene that do not mix but are seen independently.

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.

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.

Why are crystals in minerals formed from magma larger than mineral crystals formed from lava?
Answer:
Magma cools slowly inside Earth, which gives mineral crystals time to grow large enough to be seen clearly. Lava cools much more rapidly than magma when it is below the surface. In a cooling lava, mineral crystals do not have time to form and are very small.
