Muscle cramps are creating from lack of water
r-ruslan [8.4K]3 years ago
4 0

Answer:

The causes of cramps are varied:

-Low accumulation of metabolites affecting the contraction

-Low amount of electrolytes

-fluid loss

-stress associated with the environment, such as heat and cold.

Explanation:

Although these are some factors that produce cramps, they are not the only ones, it is necessary to take into account if the person has a history of cramps, or to compete at a faster rate than the rhythm of training. Sometimes these cramps occur in the types of muscles that intersect with two joints. Another possible cause of cramping has to do with the accumulation of lactic acid causing persistent contraction in the muscle.

How can convergence lead to the formation of clouds
mihalych1998 [28]
If the warm air rises high enough, the air will eventually cool to its dew point. When it cools to its dew point, it begins the process of condensation. Starting from here, as air rises, the heat of condensation stored in water vapor will gradually release.

Which factors tend to promote higher biodiversity in an ecosystem? Check all that apply.
aleksandrvk [35]

Answer: diversity of niches

, large area and warm climate

Explanation:

An ecosystem is a biotic community in which the living beings interact with their non-living physical environment. The following factors which are responsible for higher biodiversity in an ecosystem:

Diversity of niches: A niche can be define as the functional role an organism performs in an ecosystem so as to sustain it's life. For example the type of habitat, food and breeding season chosen by the organism. With the increase in the differences in the diversity of niches the organism exhibit variations and differences from the members of the same species or from the members of the other species.

Large area: The large area can support the reproduction and abundance of members which belongs to different species hence will help in promoting higher biodiversity in a region.

Warm climate: The warm climatic range will offer the chances of adaptations to the living organisms to sustain their lives in harsh environmental conditions. This will lead to evolution of  new species from the parent species.

Alu element at the PV92 locus on Chromosome 16. In this population, 436 people have a heterozygous genotype and 102 people have
Lesechka [4]

Answer:

Explanation:

According to the exercise we can infer that for the Alu insert:

p: positive allelic frequency

q: negative allelic frequency

maintaining that the population is in equilibrium we can carry out the following formula

p + q = 1 and pp + 2pq + qq = 1

looking for the genotype frequency we clear and obtain the following data

genotype frequency of 2pq = 436/1000 = 0.436

The genotype frequency of qq = 102/1000 = 0.102

This is how we look now:

number of positive people for Alu = 1000- (436 + 102) = 1000- 538 = 46

In this way it is resolved that:

genotypic frequency of pp = 462/1000 = 0.462

  p = 0.462 + (0.436 / 2) = 0.462 + 0.218 = 0.680

q = 0.102+ (0.436 / 2) = 0.102 + 0.218 = 0.320

According to the exercise carried out it is deduced:

The value of p in the population is = 0.68

We conclude that our prognosis showing a homozygous positive genotype is: 0.462
