One of the effects of the hormone secretin is to stimulate the release of bicarbonate ions into the duodenum, which neutralizes
avanturin [10]

Answer:

It will enable gut enzymes to act on the bolus during digestion.

Explanation:

The acidic presence of HCl (hydrochloric acid) in the gastric juice serves as a stimulus for the intestinal wall to produce secretin.

This hormone will act on the pancreas by stimulating the production of pancreatic juice that will contain <u>enzymes</u> (trypsinogen, amylase, lipases) and <u>HCO3⁻</u> (bicarbonate) salts, which have base composition.

With this composition that will be sent to the duodenum, there will be neutralization of acidic solution coming from the stomach and pH leveling around 8.0 (slightly basic) which is great for the enzymes that work there.

Eleanor is testing how temperature affects the hatching of chicken eggs. She has three groups of eggs, one each at 25°C (77°F),
Sever21 [200]
It's then independent variable.

This is the case because Eleanor is making these temperature changes.

Extra info.

The dependen variable would then be the result of hatching. This is the case because it depends on the different temperature to see what the effect of temperature change is affecting the time of hatching

Please help me in my homework (keep it simple,i couldnt find Science ;-; I am sorry) What is environment? What are three main as
meriva

Answer: It is then the space in which the life of living beings and the interaction between them and other things takes place. It is made up of living organisms, abiotic elements and artificial elements. It includes physical, chemical and biological components of the organisms and elements that form it. It is important because it is the place of habitat of humanity, it provides natural elements such as water and food, it provides fuels and raw materials that serve to manufacture artificial things and it contributes to the sustainability of life on the planet.

Explanation:

The environment is a system made up of living organisms (such as animal and plants), abiotic elements (lifeless, such as stones or water) and artificial elements (created by man, such as buildings) that are related to each other and can be modified by human action. <u>It is then the space in which the life of living beings and the interaction between them takes place</u>.

It includes physical, chemical and biological components of the organisms and elements that form it. That is, how is its composition and its function in the environment.

The importance of the environment lies in:

  • It is the place of habitat of humanity, so it influences the life of human beings and future generations. It is the space where life develops at this time with all living beings and their natural components.
  • It provides natural elements such as water and food since it offers all its natural resources needed by the human being.
  • It provides fuels and raw materials that serve to manufacture the artificial things we use daily, to build houses, have light, transport, among many other benefits to exist.
  • In the environment we find a great biological diversity of plants and animals that help maintain the ecological balance of the earth. This contributes directly to the sustainability of life on the planet. Each organism has a unique role to play.

Therefore, all societies must guarantee their care for their existence and make rational use of all their resources.

Rank from the first to the last steps to describe the correct order of events of erythrocyte death.
timama [110]

Answer:

1. erythrocyte becomes trapped in the sinusoids of spleen.

2. Spleen macrophages digest the erythrocytes.

3. Hemoglobin is broken down into amino acids, iron and bilirubin.

4. Iron ions and amino acids are recycled to make new hemoglobin in red bone marrow. Bilirubin is sent to liver for excretion.

Explanation

Aging erythrocytes are trapped in the sinusoids of the spleen, where they are digested by macrophages. Within the macrophage, hemoglobin is broken down into amino acids, iron ions, and bilirubin.

Iron ions or heme ion and amino acids then move through the blood to the bone marrow, where they are recycled and used to create new hemoglobin. Bilirubin travels with the help of the blood to the liver, where it is modified and then excreted.

thus, the correct order is :

1. erythrocyte becomesrapped in the sinusoids of spleen.

2. Spleen macrophages digest the erythrocytes.

3. Hemoglobin is broken down into amino acids, iron and bilirubin.

4. Iron ions and amino acids are recycled to make new hemoglobin in red bone marrow. Bilirubin is sent to liver for excretion.
