In human genetics, the allele for having freckles is inherited apart from the allele for having attached earlobes. Which one of Mendel's principles does this illustrate?
A- Principle of Alleles
B- Principle of Dominance
C- Principle of Independent Assortment
D- Principle of Segregation
Explanation:
The answer is B., because if freckles are a dominate trait between a female with freckles and a male with freckles, they're offspring will have a dominant trait of freckles..
Mendel's principle that describes this condition is known as the Principle of Independent Assortment. Thus, the correct option for this question is C.
What is the Principle of Independent Assortment?The Principle of Independent Assortment states that the two factors of each character separate out independently of the factors of the other characters at the time of gamete formation.
They get randomly rearranged in the offspring producing both parental and new combinations of new characters. According to the question, freckles are dominant over no freckles and unattached earlobes are dominant over attached earlobes.
This states that the factors of each character separate out independently. That is why the genes of these characters are not linked or associated with each other.
Therefore, the correct option for this question is C.

Which of the following statements correctly compares terrestrial and Jovian planets?
А
Jovian planets are generally warmer due to their proximity
to the Sun.
B
Terrestrial planets have longer
periods of revolution.
С
Terrestrial planets are denser due to their rocky composition.
D
Jovian planets are smaller in diameter.
Answer: C
Explanation: terrestrial planets are denser then the Jovian (Outer) planets since they are mostly made of rocky material, while the Jovian planets are gaseous.
Saturn, for example, would theoretically be able to float in water due to its low average density.
In DNA what is the complementary strand to GGACG?
Answer:
CCTGC
Explanation:
Adenine (A) and Thymine (T) are base-pairs whilst Cytosine (C) and Guanine (G) are base-pairs as well. Although they only go in the order A-T and C-G, you will never see Adenine and Cytosine together on a DNA strand.
someone please thoroughly explain lac operon and trp operon
Thanks
Answer:
Like the lac operon, the trp operon is a negative control mechanism. The lac operon responds to an inducer that causes the repressor to dissociate from the operator, derepressing the operon. The trp operon responds to a repressor protein that binds to two molecules of tryptophan.

Heredity is the passing on of traits from parent to offspring. Heritable information is important for life to continue. What is the role of meiosis in heredity?
Write your answer in the space below.
Answer:
Meiosis helps create more diversity and individuality in the genes of organisms.
Explanation:
Hope this is helpful, this is what I learned last year.
Answer:Sexual reproduction allows for the passing of traits from parent to offspring. In sexual reproduction, meiosis produces gametes that have chromosomes from the parents. The chromosomes carry genetic information. When the gametes fuse during fertilization, an individual with a unique combination of chromosomes or a unique genetic make up is formed.

Amy hikes down into the Grand Canyon to see Havasu Falls, a waterfall famous for its blue-green water and rock formations.
How does water shape Earth’s surface? What is the main way the hydrosphere interacts with the geosphere at Havasu Falls? Explain how this process forms waterfalls.
Basically when water goes over the earth it corrodes it and in that way shapes the earth's surface. The hydrosphere corrodes the gyoshere at Havasu Falls.
The hydrosphere is interacts with the geosphere at Havasu falls via Erosion. The erode of waterfalls softer surface of the rocks that leads to shaping the Earth's surface.
What is Geosphere?
The geosphere is the layer of Earth which consists of solid rock and other rocky materials. In contrast it could be said that the geosphere is a part of the physical, solid Earth which excludes hydrosphere (i.e. oceans, lakes, and rivers) or the atmosphere (the layer of gases that separates the ground from space).
The term geosphere is basically the the crust portion of earth, as the crust elucidates the outer layer of earth's rigid portion.
The geosphere is basically all about processes, the rock cycle processes consisting of metamorphism, melting and solidification, weathering, erosion, deposition, and burial, these constant process are responsible for the recycling of rocks on Earth between sedimentary, igneous, and metamorphic states.
Thus, the hydrosphere is interacts with the geosphere at Havasu falls via Erosion. The erode of waterfalls softer surface of the rocks that leads to shaping the Earth's surface.

Explain why the size of a new moon would affect the appearance of a solar eclipse.
Answer:
A solar eclipse can occur only when new moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic. ... Therefore, the Moon's apparent size varies with its distance from the Earth, and it is this effect that leads to the difference between total and annular eclipses.

A single cell of testis divides to produce:
a. 4 sperms.
b. 6 sperms.
c. 2 sperms.
d. a single sperm.
Answer:
Each primary spermatocytes goes through the first meiotic division, meiosis I, to produce two secondary spermatocytes, each with 23 chromosomes (haploid). Just prior to this division, the genetic material is replicated so that each chromosome consists of two strands, called chromatids, that are joined by a centromere.
Answer:
Assertion In the testis, spermatogenesis occurs in the seminiferous tubules and testosterone secretion takes place from the Sertoli cells. Reason Testosterone brings growth and maturation of secondary s3x organs and also the development of accessory s3x characters.
