Which of the following statements is true?
A.
The Earth's lithosphere is entirely made up of liquid magma.
B.
The Earth's mantle is made up of tectonic plates.
C.
The Earth's mantle is made up of continents.
D.
The Earth's lithosphere is made up of tectonic plates.
Answer:
D. The Earth's lithosphere is made up of tectonic plates.
Explanation:
The lithosphere is the Earth's outermost layer. It is made up of the brittle crust and upper mantle. Lithosphere is consist of huge slabs known as tectonic plates. These plates are present on the top of molten layer (partially) of rock. The heat from the mantle allows the bottom of the rocks soft and cause plates to move.
There are two main types of tectonic plates called oceanic and continental.
Hence, the correct answer is "D. The Earth's lithosphere is made up of tectonic plates."
The Earth's lithosphere is made up of tectonic plates. The correct option is D.
Thus, The Earth's lithosphere, which is its solid outer layer, is made up of numerous large and small tectonic plates that move and float on the asthenosphere underneath.
Along plate borders, these plates, which are made up of both continental and oceanic crust, interact with one another, causing a variety of geologic events like earthquakes, volcanic eruptions, and the construction of mountain ranges.
Liquid magma (A) or tectonic plates (B) do not make up the complete lithosphere; rather, tectonic plates are a part of the lithosphere. The mantle of the Earth, which sits underneath the crust, is made up of solid rock materials rather than continents (C).
Thus, The Earth's lithosphere is made up of tectonic plates. The correct option is D.

Answer:
According to the diagram, cell growth and preparation occur in steps 2 and 4, corresponding to phases G₁ and G₂ of cell cycle.
Explanation:
G₁ phase consists of the beginning of the cell cycle, following the process of previous division, and occurs in a cell that prepares for a next division. In this phase growth depends on the proliferation of mRNA to increase protein synthesis.
G₂ phase —third phase of the cycle— is the continuation of the process of cell growth induced by protein synthesis. Changes occur at the level of cellular components, as preparation of the cell prior to division.

A woman heterozygous for polydactyly (extra fingers and toes), a dominant trait, is married to a normal man. What is the probability of producing an offspring that has extra fingers or toes?
Answer:
The correct answer is -50%
Explanation:
Polydactyly is a dominant trait where a person gets an extra finger or toes the dominant allele is represented by P = allele for polydactyly, and the recessive allele represented by p = normal allele
So, the heterozygous woman will be - Pp & the normal man will be - pp. The presence of one allele of polydactyly will be able to show its effect as it is dominant.
Cross between heterozygous woman & normal man:
Gametes:
P p
p Pp (Show polydactyly) pp (Normal phenotype)
p Pp (Show polydactyly) pp (Normal phenotype)
From the above Punnett square, the probability of an offspring that has extra fingers or toes will be 1/2 or 50%.
Polydactyly is a condition that occurs wherein individuals have more than the normal amount of fingers and toes. It is also a genetic condition and as well heritable.
The probability of producing an offspring with extra toes or fingers in a cross between an heterozygous and a normal is 50%.
Let P represent the dominant and p the recessive
Pp (heterozygous) and pp (normal)
(woman) P p
(man) p Pp pp
p Pp pp
50% 50%
Therefore, the probability of producing an offspring with extra toes or fingers (Pp) is 50%.

Nitrogen is required for protein formation. What is responsible for the bulk of nitrogen fixation?
A.
air
B.
animals
C.
bacteria
D.
lightning
Answer:
The factor with the responsibility for nitrogen fixation is bacteria (option C).
Explanation:
The nitrogen that contributes to the formation of proteins comes from plants. Due to the inorganic nature of nitrogen, plants require bacteria to contribute to the assimilation of this element, a process called biological nitrogen fixation.
Nitrogen fixing bacteria in plants are called diazotroph and, in some cases, establish a symbiosis with the plant's roots, the rhizobia.
The other options, air, animals and lightning, do not correspond to biological nitrogen fixers with the ability to incorporate nitrogen into plants.Why is it necessary to digest corn starch?
Answer:
Your digestive system breaks down carbohydrates into glucose, which your body uses as fuel. Without the fiber, fat or protein to slow down this process, cornstarch provides your body with energy more quickly than whole-grain carb
It is essential to digest corn starch because it is the carbohydrate that provides energy after digestion, and if it is not digested properly, various diseases will develop.
What is the digestive significance?Digestion is a process in which animals simplify complex food into smaller molecules that can be absorbed and used for energy and nutrition, and it is important for animals because it enables them to extract the nutrients they need to survive and thrive, for proper digestion, animals have a complex system of organs and enzymes that work together to break down different types of nutrients, for example, the stomach produces hydrochloric acid and enzymes that help break down proteins, while the small intestine absorbs sugars, fats, and other nutrients.
Hence, it is essential to digest corn starch because it is the carbohydrate that provides energy after digestion, and if it is not digested properly, various diseases will develop.

Reaction B: 6
A ___ + 6H2O+ energy --->C. H12O6 +6_B
What molecule does blank with letter A represent in the reaction above?
O carbon dioxide
O water
O oxygen
O ATP
Answer:water
Explanation:
During photosynthesis 6 molecules of carbon dioxide are required to synthesize a glucose molecule, hence option a carbon dioxide is correct.
What is the reaction of photosynthesis?Six carbon dioxide molecules are required, one for each carbon atom in glucose. As a byproduct of water oxidation, 6 molecules of oxygen are created, 6CO2+6H2O→C6H12O6+6O2.
The endergonic pathway requires free energy, which is provided by sunlight. Plants absorb carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis.
Organisms primarily employ two types of molecules: glucose and ATP. Both compounds are used as fuels by all living things. Both chemicals are also important in the photosynthesis process.
Therefore 6 carbon dioxide is used in reaction, hence option a carbon dioxide is correct.

Explanation:
which change would lead to higher carbon dioxide levels in the atmosphere
A. An increase in photosynthesis
B. An decrease in animal
C. An increase in the burning of fossil fuels
D. An decrease in the destruction of forests
An increase in the levels of fossil fuels results in higher carbon dioxide levels in the atmosphere. So the correct option is C.
What are fossil fuels?The components of fossil fuels are decaying plants and animals. These fuels may be burnt to provide energy and can be found in the crust of the Earth. An example of fossil fuel is coal, as well as oil and natural gas.
Coal is a substance that is typically found in sedimentary rock formations, which are collections of rock, dead plant and animal materials, and layers of silt. A chunk of coal must contain more than 50% fossilized plant material.
Shale is one sedimentary rock type that contains oil in its native form. The thick oil that may be used to generate gasoline is created by heating this substance. Typically, pockets of natural gas can be found atop oil deposits. Additionally, sedimentary rock strata devoid of oil might contain it. Methane is the main component of natural gas.
Therefore, an increase in the burning of fossil fuels will result in higher carbon dioxide levels in the atmosphere. So the correct option is C.

Answer:

Red blood cells are produced more frequently than the other types, the body produces them every second, hence option 2 is correct.
Why do red blood cells produce more frequently?Medication that promotes the formation of RBCs: Erythropoietin is a hormone that is made in the liver and kidneys and stimulates the production of RBCs in the bone marrow. Some types of anemia can be treated with erythropoietin.
In order to replace those red blood cells that eventually deteriorate and die, red blood cells are continuously created in the bone marrow. A red blood cell has a lifespan of roughly 120 days on average. Anemia and shortness of breath result from a large drop in the number of red blood cells.
Therefore, It just takes a few weeks to replenish red cell reserves because your body produces roughly 2 million new ones every second.
