An object in geometry with no width length or height is a(n)A. Angle
B. line
C. Ray
D. Point

Answers

Answer 1
Answer:

Answer: The correct answer is D) Point.

Point is represented by a dot, which has no width, length or height.

On the other hand, angle is a figure formed with the help of two rays, which share a common end point.

Line is a segment, which consists of two end points whereas ray is a part of line having only one end point. Therefore, angle, line, and ray all three have width or length.

Thus, the correct option is Point.

Answer 2
Answer: An object in geometry that has to no width, length, or height is called a point. The correct answer is D.

The wild-type coat color, agouti (AA) is dominant to solid-colored fur (aa). However, a separate gene C, when present as the recessive homozygote (cc), negates any expression of pigment from the A gene and results in an albino mouse. Therefore, the genotypes AAcc, Aacc, and aacc all produce the same albino phenotype. A cross between heterozygotes for both genes (AaCc x AaCc) would generate offspring with a phenotypic ratio of 9 agouti:3 black:4 albino. Which type of gene interaction is thisa. Complementary gene interaction.b. Duplicate gene interaction.c. Recessive epistasis.

Answers

Answer:

This is an example of recessive epistasis.

Explanation:

Gene interactions happen between genes at different levels and have implications in the phenotypic expression, causing a wide genetic variability.

Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is recessive, the interaction is known as "recessive epistasis".

Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.

In recessive epistasis, the proportion is 9:3:4.

What is Amber made up of?​

Answers

Answer:

Amber, which is in fact a fossil, is often held in the same class as semi-precious stones such as turquoise and jade because of its ornamental uses. Unlike these stones, amber is not mineralized. Rather, it is simply the fossil of resin. Most that exists today is between 30 and 90 million years old. derived from the resin of extinct species of trees.

Explanation:
Amber is fossilized resin from conifers.

Ammonia can be produced by what two processes

Answers

Answer:

transamination followed by deamination

Explanation:

Ammonia exists as ammonium ion (NH4+) at the physiological pH and is produced in our body mainly by the process of transamination followed by deamination, from biogenic amines, from amino groups of nitrogenous bases like purine and pyrimidine, and in the intestine by intestinal bacterial flora through the action of
