Why do you think mining on land would be less costly than mining in the ocean?
Answers
Explanation:
Because dense minerals are heavier and drop to the stream bottom, lighter minerals are carried along in the current of the stream. Why do you think that mining on land is less costly than mining in the deep ocean is? It is easier to get to land than the ocean and you need special equipment to go under water.
Draw a flowchart to illustrate how a change in a nucleotide in a DNA strand leads to symptoms experienced by those with sickle cell anemia.
Answers
Answer:
Explanation:
The Flowchart is in the picture below. I hope it would be helpful for you.
A nucleotide is a compound containing three component units namely a pentose sugar, a heterocyclic nitrogenous base and a phosphate group. The nitrogenous base present may be either purines or pyrimidine.
What is sickle cell anemia?The sickle cell anemia is one of a group of inherited disorders known as the sickle cell disease. It affects the shape of the red blood cells which carry oxygen to all parts of the body. In sickle cell anemia some red blood cells are sickle shaped.
Red blood cells are usually round and flexible, so that they move easily through blood vessels. The sickle shaped red blood cells are also called crescent moons. These sickle cells also become rigid and sticky which slow or block the blood flow.
SCD causes a basal substitution of adenine A to thymine T in the sixth codon of beta globin. This leads to the replacement of glutamic acid with valine in polypeptide chains of haemoglobin.

BT crops are developed by adding traits from which of the following organisms?
phytoplankton
bacteria
viruses
superweeds
Answers
Answer:
bacteria
Explanation:
'Bt' crops are genetically modified crops that contains a certain gene of a bacteria called Bacillus thuringiensis. The name of this GM or transgenic crop was coined from the bacteria used.
The gene coding for the toxic traits of the bacteria are added into Bt crops e.g cotton, hence, the crops become resistant to pest attack. Therefore, according to this question, BT crops are developed by adding traits from BACTERIA.

i. Consider how a model is different from an actual human body.
ii. Describe the limitations of a model
Answers
Answer:
The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
The circulatory and respiratory system work together to provide oxygen and remove carbondioxide gas.
How circulatory and respiratory system work together?The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in to bring oxygen and out of the lungs to remove carbondioxde gas from the body. Blood moves into the lungs to bring carbondioxide gas and to load oxygen with the help of pumping of heart.
So we can conclude that circulatory and respiratory system work together to provide oxygen and remove carbondioxide gas.

Which of the following stages of photosynthesis involves carbon fixation, reduction reactions, and the ribulose 1,5-bisphosphate regeneration?
photoreduction
light-independent reaction
light-dependent reaction
first stage photosynthesis
Answers
Answer:
light-independent reaction
Explanation:
Photosynthesis, which is a unique metabolic process where plants synthesize their food (glucose) in the presence of sunlight, occurs in two stages namely: light dependent stage and light-independent stage.
The light independent stage is also known as dark stage because it does not require light to occur. It occurs in the stroma of the chloroplast where ATP and NADPH are used to fix carbon into the production of glucose. This stage involves three major processes:
- Carbon fixation of CO2
- Reduction reactions of G3P
- Regeneration of ribulose 1,5-bisphosphate (RUBP).

The ____________________ endoplasmic reticulum has a role in transporting proteins to different compartments in the cell.
Answers
Answer:
The rough endoplasmic reticulum works with the Golgi apparatus to move new proteins to their proper destinations in the cell. The membrane of the RER is continuous with the outer layer of the nuclear envelope. Smooth endoplasmic reticulum does not have any ribosomes attached to it, and so it has a smooth appearance.
Explanation:
The rough endoplasmic reticulum has a role in transporting proteins to different compartments in the cell.
What is Protein transporting?Protein transporting may be defined as a process through which proteins are transported from one cellular organelle to another after being synthesized in the rough endoplasmic reticulum along with the Golgi complex.
Due to having ribosomes on their surface, the rough endoplasmic reticulum is known as the site of protein synthesis. Due to the presence of ribosomes, their surface is not as smooth as compared to the smooth endoplasmic reticulum.
The protein after synthesis packed into the spherical-shaped vesicles which are then fused with the membrane of a specific cell organelle in order to function properly.
Therefore, the rough endoplasmic reticulum has a role in transporting proteins to different compartments in the cell.

FORMS : Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.
2. Lava flows are streams of molten rock that pour or ooze from an erupting vent. Lava is erupted during either nonexplosive activity or explosive lava fountains.
FORMS : Lava forms when magma erupts from a volcano. As pressure is released gases, dissolved in the magma, bubble out so the composition of lava changes. Most lava flows are formed by the eruption of hot.
3. A shield volcano is a type of volcano usually composed almost entirely of fluid lava flows. It is named for its low profile, resembling a warrior's shield lying on the ground.
Lavas, particularly basaltic ones, come in two primary types: pahoehoe (pronounced 'paw-hoey-hoey") and aa (pronounced "ah-ah"). Both names, like a number of volcanological terms, are of Hawaiian origin. A third type, pillow lava, forms during submarine eruptions.
Answer
Volcano A - Cinder Cone Volcano
Volcano B - Composite Volcano
Volcano C - Shield Volcano
4. Cinder cones are known for their very violent, explosive, exciting eruptions. (A)
Composite volcanoes are explosive, towering giants. (B)
Shield volcanoes quietly produce broad, massive structures through lava flows. (C)
5. Composite volcanoes have very sticky and thick lava, which can make them very explosive when they erupt: gas bubbles that are trapped in the magma chamber find it hard to escape through the viscous rock. They can also spurt lots of hot ash and rocks into the air, making them extremely dangerous.

What do you mean by genotypes?The genotype of an organism is its complete set of genetic material. Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location.
Genotype is the genetic make-up of an individual organism. Your genotype functions as a set of instructions for the growth and development of your body. The word 'genotype' is usually used when talking about the genetics of a particular trait (like eye colour).
The different types of genotypes are- homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp). The homozygous dominant and the heterozygous genotypes show the same phenotypes.
