Which allele combination represents a male who has an X-linked recessive disorder?

Answers

Answer 1

Answer: Without the answer options I cannot tell you the answer exactly, however X linked disorders are found only on X chromosomes and are indicated by a lowercase letter next to the X. Xr would be an example of the notation. A male has one X chromosome and one Y chromosome, where females have two X chromosomes.
The allele combination of a male with an x linked recessive disorder would look something like XrY.

Answer 2

Answer:

The answer is to the question is A:XrY

An organism is found that has the following traits Produces seeds has a vascular system multicellular what kingdom does this organism most likely belong to? A. Animalia B. Plantae C. Protista D.Fungi

Answers

Answer:

Kingdom Plantae

Explanation:

All living organisms were classified into a large group called KINGDOM, based on the certain features or characteristics that they possessed. Organisms in Kingdom Plantae are multicellular eukaryotic organisms that are non-motile and usually found on substrate materials.

Organisms in this Kingdom are further divided into different divisions. The organism described to produce seeds and having a vascular system in this question belongs to a group under Kingdom Plantae called Angiosperms i.e. seed bearing plants.

All other divisions mentioned in the question do not produce seeds. Seed-bearing is peculiar to plants.

Which sequence represents a cross section of the bilayer

Answers

hydrophillic head, hydrophobic tail, hydrophobic tail, hydrophillic head

Answer:

The correct order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.

The plasma membrane is a lipid bilayer, that is, a layer formed of two layers of phospholipids.

A phospholipid is made up of two parts; hydrophilic polar heads and hydrophobic lipid tail.

The two layers are arranged in such a way that the hydrophilic parts are present outwards and the hydrophobic tails are sandwiched between the polar heads of two layers.

Thus, the order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.

Genetic information is carried in ATP molecules.
True
False

Answers

Answer: FALSE

Explanation:

Genetic information is a information which is stored in cells of the living beings in the form of nucleic acids which can be either DNA (deoxyribonucleic acids) or RNA (ribonucleic acid). These nucleic acids store information in the coded form. These are passed from the parents to their offspring through reproduction. The ATP (adenosine triphophate) is the energy molecule present in the body after the oxidation and breakdown of food by the process of respiration. This does not carry the genetic information.

False genetic information is carried by DNA not ATP, ATP carries energy
