Jhich best describe the role of small intestine in digestion?
A. It temporarily stores the food
B. Secrets bile to help in digestion.
C. Helps in the absorption of nutrients from food.
D. It carries food from the mouth to the stomach.
The best option that describes the role of the small intestine in digestion is (C) it helps in the absorption of nutrients from food.
What is small intestine?The small intestine is a vital part of the digestive system, and its main role is to facilitate the absorption of nutrients from the food we eat. After food is partially digested in the stomach, it enters the small intestine, where it is broken down further by enzymes secreted by the pancreas and bile from the liver.
The walls of the small intestine are lined with small finger-like projections called villi, which greatly increase the surface area available for nutrient absorption.
As food passes through the small intestine, nutrients such as carbohydrates, proteins, and fats are absorbed through the villi and into the bloodstream, where they can be transported to the cells throughout the body to be used as energy or for other purposes.
In addition to nutrient absorption, the small intestine also plays a role in the digestion of carbohydrates and proteins, and it helps to regulate the release of digestive enzymes and hormones.
Overall, the small intestine is a crucial component of the digestive system, and its proper functioning is essential for maintaining good health and well-being.

the anthers in this flower located above or below the stigma
Answer:
The anther produces pollen (male reproductive cells). The filament holds the anther up. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary. Male reproductive cells travel down the tube and join with the ovule, fertilizing it.

How would you explain this to him? Describe what the glycemic index is and how this is very important in developing a nutritional diet.
Answer:
The glycemic index allows people with diabetes to follow a balanced diet by consuming foods with a low glycemic index, which helps to avoid increasing the level of sugar in the blood.
Explanation:
The glycemic index is important to know when a certain food raises the level of sugar in the blood.
A good diet for people with diabetes is determined by foods that have a low glycemic index between 1 to 55; Some of the foods that can help us regulate the level of sugar in the blood are the following:
- Breads and cereals that are exclusively whole grains.
-Legumes like beans and lentils.
-Fruits such as: peach, pear, apples, cherries and prunes.

-bird
-crocodile
ANATOMICAL FUNCTION-
-walking, and hopping
-swimming, walking/crawling

Human - Using tools, picking up and holding objects
Whale - Swimming
Cat - Running, walking, jumping

Bird - Walking, and hopping
Crocodile - Swimming, walking/crawling
It was kind of confusing because both birds and bats fly and flap their wings, but birds also walk and hop, so this is correct
Selective breeding produces cultivated varieties of plants within the same genus. Cultivars often use ____
names following the genus, which are not based in Latin. For example, for a hybrid tea rose which is
black, it is called Rosa'Black Baccara'.
Answer:
Binomial
Explanation:
Answer:
The correct answer is - cultivar epithet.
Explanation:
Selective breeding results in cultivated varieties of plants of the same genus. These cultivated varieties are called cultivar names. This cultivar name consists of the scientific Latin botanical genus name followed by a name called as cultivar epithet.
Vernacular language is the full cultivar epithet of the species such as an example given here of herbal hybrid tea called Rosa 'Black Baccara'.

3. Why does asexual reproduction result in offspring with identical genetic variation?
Answer:
Because the offspring are not getting genetic material from another organism.
Explanation:
Match each movement with the correct label.
flexion
extension
adduction
abduction
elevation
depression
medial rotation
lateral rotation
Answer:
flexion - depression
extension - elevation
adduction - medial rotation
abduction - lateral rotation
Explanation:
Flexion is the process of bending an arm or leg. It occurs as a result of the contraction of the muscles. Depression is a downward movement. Hence, flexion refers to the depression of an arm or leg.
Extension is the process of stretching the body parts. Elevation is an upward movement. Hence, extension refers to the elevation of body parts.
Adduction is the movement of a limb or other part of the body towards the midline or another part of the body. The movement of the limb towards the midline of the body is known as medial rotation.
Abduction is the movement of a limb or other part of the body away from the midline of the body. The movement of the limb away from the midline of the body is known as lateral rotation.
Are chloroplasts found in animal cells ?

Describe how DNA and RNA direct cell differentiation. Give an example of how environmental factors may influence cell differentiation.
Answer:
1- DNA: a specific DNA sequence encodes a transcription factor which activates the expression of target genes involved in cell differentiation
2- RNA: short non-coding RNAs may bind to enhancer regions and thus activate the expression of target genes involved in cell differentiation
3- Environmental factor: temperature may control the expression of genes involved in cell differentiation pathways
Explanation:
The deoxyribonucleic acid (DNA) contains the genetic material required to encode proteins. Some of these proteins are transcription factors involved in the activation of diverse signaling pathways, including, for example, cell differentiation and proliferation. On the other hand, microRNAs (miRNAs) are short non-coding RNAs that have the ability not only to repress but also to activate transcription by binding enhancer sequences. The miRNA activation mechanism has recently been discovered. In consequence, some miRNAs may potentially activate the expression of target genes involved in cell differentiation (e.g., c-myc gene). Finally, environmental factors (e.g., nutrient availability, salinity, temperature, etc.) may also activate gene expression and thus control diverse pathways such as cell differentiation, cell proliferation and cell death (apoptosis).

Explain the effects of air pollution on several European countries. (Site 1)
Answer:
Air pollution harms human health and the environment. In Europe, emissions of many air pollutants have decreased substantially over the past decades, resulting in improved air quality across the region. However, air pollutant concentrations are still too high, and air quality problems persist. A significant proportion of Europe’s population live in areas, especially cities, where exceedances of air quality standards occur: ozone, nitrogen dioxide and particulate matter (PM) pollution pose serious health risks. Several countries have exceeded one or more of their 2010 emission limits for four important air pollutants. Reducing air pollution therefore remains important.
Air pollution is a local, pan-European and hemispheric issue. Air pollutants released in one country may be transported in the atmosphere, contributing to or resulting in poor air quality elsewhere.
Particulate matter, nitrogen dioxide and ground-level ozone, are now generally recognised as the three pollutants that most significantly affect human health. Long-term and peak exposures to these pollutants range in severity of impact, from impairing the respiratory system to premature death. Around 90 % of city dwellers in Europe are exposed to pollutants at concentrations higher than the air quality levels deemed harmful to health. For example, fine particulate matter (PM2.5) in air has been estimated to reduce life expectancy in the EU by more than eight months. Benzo(a)pyrene is a carcinogenic pollutant of increasing concern, with concentrations being above the threshold set to protect human health in several urban areas, especially in central and eastern Europe.
"Air pollution is causing damage to human health and ecosystems. Large parts of the population do not live in a healthy environment, according to current standards. To get on to a sustainable path, Europe will have to be ambitious and go beyond current legislation."

Identify how Newton's third law of motion was responsible for the astronaut's return to the space station.
Answer:
sorry i cant understand clearly
Explanation:
i hope its help more
Answer: The equipment will "push back" on the astronaut with the same amount of force.
Explanation: Newton's third law of motion can be summed up as "For every action, there is an equal and opposite reaction." This means that when the astronaut applies force to push the object, that object will apply an equal amount of force to the astronaut.
