An organism that reproduces sexually has a diploid number of 30. How many
chromosomes will a gamete of this organism have?

Answers

Answer:

Gamete of organism has a haploid number of chromosomes.

2n = 30

n = 15

A diploid cell containing 30 chromosomes will result in 15 chromosomes in each of the 4 daughter cells after meiosis occurs.

After first nuclear and cellular division (Meiosis I), each daughter cell will only have 15 chromosomes as homologous chromosomes are broken apart at Anaphase I of meiosis I. Chromosomal number is halved. After the second nuclear and cellular division (Meiosis II), each daughter cell will also have 15 chromosomes. This time, instead of the chromosomal number being halved, their chromosomal contents are halved. Sister chromatids are separated at Anaphase II of Meiosis II, resulting in daughter chromosomes each.

Here is an image of the mitochondria. Mitochondria numbers can differ between cell types based on the function of the cell. Which of these cells would contain the highest number of mitochondria? A) skin cell B) lung cell C) muscle cell D) red blood cell.

Answers

The cell organelle that produces most of the energy for cell functioning and growth is mitochondria. Mitochondria is a double membrane organelle that varies in number in cells.

The highest number of mitochondria is found in:

Option C) Muscle cells

The function of mitochondria can be explained as:

Muscle cells and tissues are bodily organizations that constantly and frequently move so to provide energy for the actions the muscle cells have the highest number of mitochondria.

The skin and lungs cells vary in mitochondrial quantity and may contain hundreds or thousands. Some amount of cell requires more amount of energy as compared to others so the number of mitochondria in those cells will be more.

The blood cell of mammals lack mitochondria in their structure.

Therefore, muscle cells have the highest number of mitochondria.

Photoperiodism isn't the same as Photoperiod because Photoperiodism merely refers to the potential of the plant to incite flowering relative to the changes in the photoperiod.

Read the excerpt from "The Lady Maid's Bell." I had been near a week at Brympton before I saw my master. Word came that he was arriving one afternoon, and a change passed over the whole household. It was plain that nobody loved him below stairs. Mrs. Blinder took uncommon care with the dinner that night, but she snapped at the kitchen-maid in a way quite unusual with her; and Mr. Wace, the butler, a serious, slow-spoken man, went about his duties as if he'd been getting ready for a funeral. He was a great Bible-reader, Mr. Wace was, and had a beautiful assortment of texts at his command; but that day he used such dreadful language that I was about to leave the table, when he assured me it was all out of Isaiah; and I noticed that whenever the master came Mr. Wace took to the prophets. Which best describes a gothic element in the excerpt and the social attitude it reveals? The arrival of Mr. Brympton causes fear, revealing that men are powerful in the world. Mrs. Blinder prepares a dinner well, revealing that cooking is considered the highest art. Mr. Wace reads the Bible, revealing that religion is no longer a respected institution. The servants do not like the master, revealing that having servants is no longer acceptable.

where is earth's magnetic north pole?​

Answers

Answer:

The north magnetic pole is a point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down)

Explanation:

There is only one location where this occurs, near (but distinct from) the geographic north pole. The geomagnetic north pole, a related point, is the pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's actual magnetic field.

The Earth's magnetic pole is situated at west of the Ellesmere Island in northern Canada at the geographical location of 81°18′N 110°48′W.

What is the Earth's magnetic pole?

The generation of the Earth's magnetic field occurs deep within the Earth's interior, in a layer which is known as the outer core to be more precise. Here, the convective energy from the slow-moving molten iron is converted to the electrical and magnetic energies.

The north magnetic pole of the Earth moves over time according to the magnetic changes and flux lobe elongation in the Earth's outer core. In the year 2001, it was determined by the Geological Survey of Canada to lie west of the Ellesmere Island in northern Canada at the geographical location of 81°18′N 110°48′W. It was situated at 83°06′N 117°48′W in 2005.

The pedigree below depicts a dominant trait. What is the genotype of individual I-1 (use the letter A for a dominant allele and a for a recessive allele)? How did you come to this conclusion? Using your best grammar, write 3-5 sentences.

Answers

A pedigree chart is a diagrammatic representation showing the occurrence and appearance of phenotypes of a particular gene/traits and its ancestors from one generation to the next establishing relationships between individuals in a family.

Using the letter A for a dominant allele and a for a recessive allele, the genotype of individual I-1 is Aa.

In the key pedigree nomenclature, an individual marked with the black ink is affected with the trait (and this trait is dominant - A). Looking at the F1 generation, there are males affected and females as well. For inheritance of the trait, just one copy is enough to become affected. Therefore, the male parent is heterozygous for the trait and the female normal (aa) to enable the production of both affected and non-affected individuals.

A mutation in the sperm cell will most likely result in heritable change ton the attributes of organisms.

Mutations that happen in vegetative cells such as skin, lung, and brain cells cannot be passed on to future generations.

Heritable mutations are those changes to the DNA sequence of sex cells. Changes elicited by such mutations are passed to future generations because they are germline based.

Sperm cells are sex cells. Thus, changes that occur as a result of mutation to sperm cells are most likely heritable.
