Sex-linked traits are more common in

Biology
2 answers:
Maurinko [17]3 years ago
8 0

Answer:

X-Chromosomes.

Explanation:

Characters determined by a gene located on only the X-chromosome are said to be sex-linked. Such traits show a different pattern of inheritance in males and females. For example, a recessive allele on the X-chromosome

• would be masked in a female if the corresponding allele on the other X-chromosome is dominant;

• would always be expressed in a male because the Y-chromosome does not have a corresponding(active) allele.

Thus, the female may posses a homozygous or heterozygous allelic pair for a sex-linked character, but a male will only have one allele for it.

Biochemistry basics
andrew-mc [135]

Answer: Read my explainantion;)

Explanation:

The key thing to remember is that biochemistry is the chemistry of the living world. Plants, animals, and single-celled organisms all use the same basic chemical compounds to live their lives. Biochemistry is not about the cells or the organisms. It's about the smallest parts of those organisms, the molecules.

Where is the best place to find information about the hazards that are associated with a compound
Marizza181 [45]
Material Safety Data Sheet (MSDS) is the best place to find information about the hazards that are associated with a compound. It is a document that gives the information on the potential hazards such as health, fire, reactivity and environmental and how to work safely with the chemical products.

This type of membrane transport moves substances against the concentration gradient from an area of low concentration to an area
sashaice [31]

<u>Answer</u>:- Active transport

<u>Explanation</u>:-

There are two types of membrane transports

1. Passive transport - this type of transport occurs without the input of any energy and the molecules move along the concentration gradients that is from <em>high concetration to low concentration.</em>

2. Active transport- this type of transport takes place to move the molecules against the concentration gradient that is from <em>low concentration to high concentration.</em>

<em>The active transport is of two types:</em>

1. <em>Primary active transport-</em> in this type of transport <em>ATP</em> is used as an energy source to move the substances against the concentration gradient.

2.<em>Secondary active transport</em> - in this type of transport the gradient formed by the active transport is utilized and it involves the movement of 2 substances at a time aross the membrane. That is the movement of one molecule is coupled to another.


  • The membrane proteins that are associated with active transport are called as <em>carrier proteins</em>. These proteins have a binding site for the molecules that they transport. Once they bind to the specific molecules, a conformation change is induced and this leads to the transport of the molecule across the membrane.

So, the <em>active transport is basically responsible for utilizing the energy from ATP and carrier proteins to move the substances across the membrane against their concentration gradient i.e. from low concentration to high concentration.</em>
