Match the digestive organ on the left with its function.

Biology
1 answer:
RUDIKE [14]2 years ago
6 0

Answer:

pancreas: secretes digestive enzymes into the small intestine

esophagus: the place where peristalsis takes place

small intestine: area of the digestive tract where most nuturients are absorbed

stomach: area of the digestive tract that follows the esophagus

large intestine: area of the digestive tract where mostly water is absorbed

Explanation:

peristalsis: so the food can move down towards your stomach, independently of gravity

pancreas: helps your stomach become the ultimate weapon to destroy anything that gets in there with its enzymes

small intestine: it is really really long -> more time to absorb nutrients

large intestine: like a farm of bacteria, the most exotic things that somehow made it through all the way here are finally destroyed -> also, water absorbtion: your body wants to retain as much as possible, this is how and where stool formation takes place

<span>Controlled experiment is an experiment done under controlled conditions in which only one variable at a time is changed in order to isolate the results. An alternative to a controlled experiment would be a correlation study. A correlation study is a research method in which two variables are compared (what are the similarities and the difference between them). So, correlation study is a type of controlled experiment in which ove variable is changed and the dependence with another variable is analyzed.</span><span />

Classify the steps involved in the formation of a solution as being endothermic or exothermic. separation of solute molecules se
Alexxx [7]

Answer:

<em>Endothermic reactions:  separation of solute molecules , separation of solvent molecules</em>

<em>Exothermic: formation of solute-solvent interactions</em>

Explanation:

An endothermic reaction can be described as a reaction which requires energy. Usually, the energy is taken in the form of heat from the environment. For example: the separation of solute and solvent molecules.

An exothermic reaction can be described as a reaction in which energy is released during a reaction. For example, a solute and a solvent reaction. Energy is usually released in the form of heat during an exothermic process.

In humans, MN blood types are determined by an autosomal gene with two alleles: LM and LN. In one population of 592 people, ther
RoseWind [281]

Answer:

148

Explanation:

According to Hardy-Weinberg equilibrium,

p + q = 1

p² + 2pq + q² = 1 where,

p = frequency of dominant allele

q = frequency of recessive allele

p² = frequency of homozygous dominant genotype

2pq = frequency of heterozygous genotype

q² = frequency of homozygous recessive genotype

Here,

Total population = 592

Number of NN people = 148

Frequency of N blood group or NN genotype (q²) = 148/592 = 0.25

q = √0.25 = 0.5

p = 1 - q

= 1 - 0.5 = 0.5

Hence, p = 0.5

Frequency of MM genotype = p² = 0.25

Number of people with MM genotype = 0.25*592 = 148

Hence, 148 people will have MM genotype or M blood group.

Which trophies level contains more energy: strophic level of herbivores or a trophies level of carnivores? Why?
Elden [556K]
Herbivores. The eat directly from the producers. 10% of the producer's energy goes to herbivores, while only 10% of the 10% energy the herbivores had goes to carnivores.
