Those mutated genes are most commonly recessive. Females have two X chromosomes so they can have a chromosome with the mutated gene and one with the healthy gene. The healthy gene is dominant so the disease won't manifest, and the woman is only a carrier. Males have only one X chromosome and an Y chromosome. If they have the mutated gene on the X chromosome they won't have another X chromosome with the healthy gene.

To summarize, men can't be carriers and they only need one copy of the mutated X-linked gene while women need two copies of the mutated gene.

An ecologist wants to know if diversity in a forest system is likely to decrease when an invasive species is introduced. This in

Alona [7]

Answer:

A model in which oak has a positive transition rate to the invasive and the invasive has a positive transition to oak.

Explanation:

An invasive species is the one which is non-native to the given ecosystem. Its growth hampers balanced ecological parameters and disturbs food web as well as normal flora.The overall effect of invasive species is decreasing biodiversity in selected ecosystem. As the ecologist needs to understand effect of this invasive species, firstly it is important to understand the transition of oak tress to invasive form. The transition rate is one of the deciding factor to introduce diversity in ecosystem. Also if the invasive form has the ability to revert back to original oak tress it would restore the original ecosystem. Thus a model in which oak has a positive transition rate to invasive and the invasive has a position transition to oak can be selected for the analysis. In other models, the final trnasition to grass would introduce lot of biodiversity in selected ecosystem which would be of little importance to understand transition rate.

<h2>Wide-Spread of Malaria</h2>

Explanation:

The sickle cell attribute don't experience the ill effects of the illness.
Analysts found that the sickle cell quality is particularly predominant in <em>areas of Africa hard-hit by malaria.</em>
<em>Their red platelets, containing some unusual hemoglobin, watch out for sickle when they are contaminated by the jungle fever parasite. </em>
Intestinal sickness is lowlands of East Africa thus the sickle cell allele became normal since it gave security against jungle fever.
Sickle cell ailment (SCD) influences a great many individuals all through the world and is especially basic among those whose predecessors originated from sub-Saharan Africa.

Harry is a healthy man who is 30 years of age. using this information, calculate his approximate target heart rate zone for mode

klemol [59]

Answer: <span>95 to 133 bpm</span>

The equation for maximum heart rate would be:
max HR= 220- age
max HR= 220-30= 190

The equation to find the target for heart beat in medium intensity exercise would be:
target HR= max HR * 50-70%= 190 * 50-70%= <span>95 to 133 bpm</span>
