The nitrogen in the air cannot be used by producers and consumers. It must be fixed or converted by bacteria in the ground into a useable form for plants called nitrates. Some plants called legumes (beans and clover) actually have bacteria in their roots.

3. In pea plants, inflated pods are dominant to constricted pods.

qwelly [4]

Answer:

Let's consider the alleles for a true- breeding inflated pod to be PP. Let's consider the alleles for the constricted pod to be pp. The punnet square for this can be shown as:

p p

P Pp Pp

The results from the punnet square show that there will be 100% (4:0) inflated pods offsprings produced from this cross. However, their genotype will be heterozygous.

A cross between the constricted pods can be shown as:

p p

p pp pp

The results from this cross show that the offsprings produced will be 100% constricted pod plants.

While listening to sad rather than happy music, people are more likely to perceive a spoken work as mourning rather than morning

Shtirlitz [24]

Answer:

top-down processing

Explanation:

When the perception is formed starting from a larger concept or object and then it is focused on to more detailed information, then such a method of forming perception is termed as top down processing.
This processing takes into consideration the general impressions and then focusing on the finer details to make a final perception.
Due to the top down processing the circumstances under which a particular emotion or object is perceived influences our expectations in that particular situation.
Therefore, when we listen to sad music our brain already perceives that the word spoken would be in context to the current situation and hence, the word gets perceived as mourning rather than morning and this is an example of top down processing.

Sickle cell anemia is an example of a disorder that can be detected in newborns by: using the apgar scale. taking a urine sample

Basile [38]

The sickle cell anaemia is a condition, in which the red blood cells of the affected person becomes sickle shaped. This condition is caused by an autosomal recessive condition, which is a genetic disorder. Due to the sickle shaped RBC, the Hemoglobin becomes unable to bind with the oxygen efficiently, as a result it causes anaemia.

As this condition is caused by genetic abnormality, it can be detected by a DNA analysis.

Compare sickle cell disease and malaria. compare sickle cell disease and malaria. sickle cell disease and malaria are both genet

Luden [163]

The correct answer is the final option - sickle cell disease and malaria are both potentially lethal diseases.
The other options are incorrect because sickle cell disease is an inherited disease, but malaria is not - it is an infectious disease. However, both of these disease are quite dangerous, and may have severe consequences (such as death) if they are not properly treated.
