Answers

Answer:

yeah

Explanation:

it's obviously D . it's a heritable change because the mutation in the sperm cell is gonna cause a mutation in the zygote

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.

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.

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.
