why is climate change a serious threat to the least developed countries practicing agriculture as their main occupation mountain region island and low lying countries​

Answers

Answer 1

Answer:

Increase in sea level on the low lying countries which leads to degradation and salinification thereby making the soil non-arable. Meanwhile on the mountain regions, melting glaciers caused by rain falling on snow leads to mountain floods, avalanches and extreme rockslide and thereby disrupting agricultural produce and wildlife.

What is the function of bile in the digestion of fats in the small intestine?

Answers

Answer:

Bile is a fluid that is made and released by the liver and stored in the gallbladder. Bile helps with digestion. It breaks down fats into fatty acids, which can be taken into the body by the digestive tract.

Explanation:

When digesting fats, bile acts as an emulsifier to break the large fat globules into smaller emulsion droplets. Emulsified fats provide a larger area for the fat-digesting enzymes (lipase) to act, making the process quicker. Bile acts as a good solvent.

A sample from a stock of a bacterial colony in liquid media was diluted by a factor of 106, and 2 ml of this dilution was spread on a Petri dish of solidified media. 56 colonies were observed. What was the concentration of bacteria of the initial stock?

Answers

Answer:

28 × 10⁶ colonies/ml

Explanation:

Let C be the concentration of bacterial in the initial stock. When it is diluted by a factor of 10⁶, the new concentration is C' = C/10⁶.

When 2 ml of this concentration is spread on a Petri dish of solidified media, 56 colonies were produced. The number of colonies, n after spreading the 2 ml of C' is C' × 2 ml = 2C' = 2C/10⁶.

So, n = 2C/10⁶.

Since the number of colonies after spreading on a Petri dish of solidified media is 56, n = 56 colonies.

So, 2C/10⁶ = 56

Making C subject of the formula, we have

C = 56 × 10⁶/2

C = 28 × 10⁶ colonies/ml

So, the initial concentration of bacteria is 28 × 10⁶ colonies/ml

¿Porque las vitaminas, las sales minarales y el agua se consideran reguladores?

Answers

Answer:

Vitamins and minerals boost the immune system, support normal growth and development, and help cells and organs do their jobs. For example, you've probably heard that carrots are good for your eyes. It's true! Carrots are full of substances called carotenoids (pronounced: kuh-RAH-teh-noydz) that your body converts into vitamin A, which helps prevent eye problems.

Vitamin K helps blood to clot, so cuts and scrapes stop bleeding quickly. You'll find vitamin K in green leafy vegetables, broccoli, and soybeans. And to have strong bones, you need to eat foods such as milk, yogurt, and green leafy vegetables, which are rich in the mineral calcium.

From left to right, the correct order of the minerals from the least hard to the hardest is ⇒ Graphite, Talc, Gypsum, Calcite, Fluorite, Apatite, Magnetite, Pyrithe, Feldespat, Quartz.

Theoretical frame:

Hardness is one of the physical properties of minerals and is a significant one when identifying and recognizing them.

Hardness measures the resistance level of a surface to abrasion. In the specific case of minerals, it measures how minerals resist being scratched or penetrated.

The hardness level is determined by an attempt to scratch or produce a mark on an unmarked surface using sharp elements, such as nails, copper coin, glass, or a steal knife. Notice that these elements also vary in their hardness.

There are different methods used to define hardness, and they are not comparable to each other. The Mohs hardness method defines an ordinary qualitative scale that characterizes the mineral according to their resistance to being scratched by a harder element.

According to the Mohs hardness scale, the level in which the given minerals are placed is as follows,

Graphite ⇒ 1 - 2Talc ⇒ 1Gypsum ⇒ 1.5 - 2Calcite ⇒ 3Fluorite ⇒ 4Apatite ⇒ 5 Magnetite ⇒ 5 - 6.5Pyrithe ⇒ 6Feldespat ⇒ 6 - 6.5Quartz ⇒ 7

Please use the following information to answer the questions below. The southern grasshopper mouse feeds regularly on the Arizona bark scorpion, the most venomous scorpion in the United States. While attempting to capture the scorpion, the mouse usually gets stung multiple times by the scorpion but does not seem to be affected. While attempting to capture the scorpion, the mouse's heart rate increases, and there is an increase in epinephrine in the mouse's blood. What nervous system division is responsible for the mouse's physiological state

Answers

The sympathetic nervous system is responsible for the mouse's physiological state.

 

The nervous system divides into the central nervous system and peripheral nervous system.

In the central nervous system, we have the brain and the spinal cord.

The peripherical nervous system, which is all the nerves that are not in the spinal cord or the brain, is divided into:

The somatic nervous system, which is the one that makes the conscious movements of our body.The autonomic nervous system consists of:

-Sympathetic nervous system. It is the one that works under stress. It gives the fight or flight response preparing the body for a dangerous situation. It increases the heart rate and epinephrine's release. Epinephrine is a hormone that helps in this response stimulating the sympathetic system.

-Parasympathetic nervous system. It is the one that works in calm situations, like after we ate, regulating digestion, and trying to save energy for any upcoming event.

In conclusion, as there is an increase in epinephrine and heart rate, and the mouse is "fighting" against a scorpion, the nervous system division responsible for this physiological state is the sympathetic nervous system.

2. In a parent pea plant with the allele pair GG, what is the probability that one gamete will contain the g allele? Why?
3. In a parent pea plant with the allele pair gg, what is the probability that one gamete will contain the g allele? Why?

Answers

Answer:

If the gamete will get either G or g, the probability will be 1/2 of getting G.

Explanation:

all question 3 answer is that. Because all 3 of question are same. only repeated three times

In a parent pea plant with the allele pair Gg, the probability that one gamete will contain the G allele is 0.5. This is because there are two possible outcomes in which one must definitely fall. So, it is 1/2.

What is Allele?

Alleles may be characterized as the alternative form or versions of a gene that are responsible for particular traits in living organisms. They carry a code of genetic sequences within generations.

In a parent pea plant with the allele pair GG, the probability that the gamete will contain the g allele is zero. This is because there is no presence of allele g that can be determined within any gametes. So, it is not possible to get g in the pair allele of GG.

In a parent pea plant with the allele pair gg, the probability that one gamete will contain the g allele is 1 or 100%. This is because both carry g alleles. So, the probability is 100%.

Explanation:

The genetic code contains thousands of genes. Each genetic code represents a specific amino acid. Hence, option B is correct.

What is Genetic code?

A genetic code represents a set of three-letter that are a combination of nucleotides known as codons. Each of them correlates to a particular amino acid.

Amino acids are the molecules that combine to form protein which serves as the base of life. Genetic code is translated into a sequence of amino acids with the help of a codon table.

Codon is a sequence of three nucleotides that form a unit of genetic code in DNA or RNA molecules.

Therefore, the amino acid is represented by each genetic code. Thus, option B is correct.

ANSWERS:

Geosphere = burying organisms

hydrosphere = respiration of marine life

biosphere = photosynthesis atmosphere = burning things

Explanation:

This question describes the types of spheres we have. The respective activities that occur in each sphere that adds CO2 or carbon are as follows:

- Geosphere: This refers to the solid part of the Earth. Dead organisms are buried in the geosphere (soil) where their carbon remains can be deposited.

- Hydrosphere: This constitutes all of the water bodies (sea, river, stream, ocean) on the Earth. When marine organisms respire in water, carbon dioxide (CO2) is released.

- Biosphere: A sphere consisting of all living things (plant, animal, microbes etc.) on Earth. Plants as a living organisms photosynthesize and make use of carbon dioxide to produce glucose, which stores in the plant.

Atmosphere: The gaseous component of the Earth. Burning substances release carbon based gases into the atmosphere.

For each of the following structures, first indicate its function in the fetus; then, note its fate (what happens to it or what it is converted to after birth).

a. Umbilical artery
b. Umbilical vein
c. Ductus venosus
d. Ductus arterious
e. Foramen ovale

Answers

Answer:

1. Functions:

a. Umbilical artery >> carries deoxygenated blood from the fetus to the placenta

b. Umbilical vein >> transports oxygenated blood from the placenta to the fetus

c. Ductus venosus >> allows oxygenated blood from the placenta to bypass the liver

d. Ductus arterious >> allows most of the blood from the right ventricle to bypass the fetus's non-functioning lungs

e. Foramen ovale >> oxygenated blood from the umbilical vein to bypass the pulmonary circulation

2. After the bird:

1. Umbilical artery >> medial umbilical ligament

2. Umbilical vein >> round ligament of the liver

3. Ductus venosus  >> ligamentum venosum

4. Ductus arteriosus >> ligamentum arteriosum

5. Foramen ovale >> fossa ovalis

Explanation:

The umbilical artery is a paired artery localized in the abdominal and pelvic regions, which carries deoxygenated blood from the fetus to the placenta through the umbilical cord. The medial umbilical ligament is the obliterated part of the umbilical artery that arises from the internal iliac arteries. In utero, the umbilical arteries carry waste products back to the placenta, whereas the umbilical vein carries oxygenated blood from the placenta to the fetus. The round ligament of the liver (also known as ligamentum teres hepatis) is a remnant of the umbilical vein that  exists in the embryonic stage, it connects the left lobe of the liver to the umbilicus. The ductus venosus is a slender shunt that allows oxygenated blood from the placenta to bypass the liver, it connects the intra-hepatic portion of the umbilical vein to the inferior vena cava. The ligamentum venosum is an extrahepatic, slender, and fibrous remnant of the fetal ductus venosus that travels between the left portal vein and the inferior vena cava. The ductus arteriosus is a fetal artery that connects the aorta to the pulmonary artery. The ligamentum arteriosum is a nonfunctional vestige of the ductus arteriosus, it is attached to the superior surface of the pulmonary trunk. The foramen ovale is an oval-shaped, small, opening in the wall (septum) between the two upper chambers of the heart. The fossa ovalis is a vestige stricture of the foramen ovale of the embryonic heart, which forms a depression in the right atrium of the heart.

When does facilitated diffusion occur?
-When one liquid has a higher osmotic pressure than the other.
-When certain large molecules are unable to move through the membrane
without the help of channel proteins.
-When ATP is available to assist in moving molecules.
-When there's a strong membrane potential present, with the inside of the cell
being more negative than the outside of the cell.

Answers

Answer:

When certain large molecules are unable to move through the membrane without the help of channel proteins

Explanation:

Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.
