The correct answer is: a. Anticodon loop
tRNA or transfer RNA is an important component in protein synthesis (translation). Its role is to carry amino acids to the ribosome and link a matching a codon in an mRNA with the amino acid it codes for.
The anticodon located on the tRNA (anticodon loop) can bind to one or a few specific mRNA codons.
The correct option is c.
The 3' end of a tRNA molecule binds to amino acids during protein synthesis. Specifically, the CCA tail at this 3' end directly binds the amino acids.
The region of a tRNA molecule that binds to amino acids is the 3′ end. tRNA, which stands for transfer RNA, is crucial for protein synthesis in the cell. The amino acids are attached to the 3′ end of the tRNA molecule. While the anticodon loop, codon loop, and the variable loop are all important aspects of the tRNA structure, it's the 3' end, more specifically the CCA tail at this part, that directly binds to the amino acids during translation.

Population sizes will increase as new species move into the cleared area.
Invasive species will quickly take over the disturbed area.
Biodiversity will decrease in the area of the fire.
Answer:
Biodiversity will decrease in the area of the fire.
Explanation:
Biodiversity will be reduced in the area affected by fire, mainly due to factors such as habitat destruction, pollution and exploration of natural resources.
Habitat destruction occurs as a result of the urbanization, deforestation and development of large agricultural works, this destruction is also caused by globalwarming (or climate change).
In addition, air, soil and water pollution also cause biodiversity loss.
Due to environmental pollution, many species cannot establish themselves, for example due to lack of food, difficulty in accessing drinking water or the emergence of diseases.
Biodiversity can also be threatened by overuse of natural resources such as logging, reducing the number of plants in an ecosystem.
Uncontrolledhunting and fishing are also responsible for reducing the number of individuals of various species.
Biodiversity will decrease in the area of the fire.
Answer: 50 percent
Explanation:
b. marsupials.
c. placental mammals.
d. domestic animals.
Answer:
C. Placental mammals
Explanation:
The placentals are the largest group of mammals, totally dominating the class and terrestrial habitats.
Amnium, the fluid that protects the embryo from adhesions and shocks, is installed in the female's uterus for development with the help of a placenta that provides fixation and nutrients.
This breeding method, although producing a smaller number of offspring per pregnancy, has a high success rate, allowing greater chances of survival to offspring.
elastic
unitary elastic
total revenue
normal good
inferior good
Answer:
Elasticity of demand refers to the degree of responsiveness of the quantity demanded of a good or service to changes in its price.
Inelastic demand means that the quantity demanded of a good or service is not significantly affected by changes in its price. In other words, demand remains relatively stable even if the price changes.
Elastic demand means that the quantity demanded of a good or service is highly responsive to changes in its price. If the price increases, the quantity demanded decreases significantly, and if the price decreases, the quantity demanded increases significantly.
Unitary elastic demand refers to a situation where the percentage change in the quantity demanded is equal to the percentage change in price. In other words, the demand is neither inelastic nor elastic.
Total revenue is the total amount of money received from the sale of a good or service. It is calculated by multiplying the price of the good or service by the quantity sold.
Normal goods are goods for which demand increases as consumer income increases. These goods are considered to be necessities or luxury goods that people tend to buy more of when they have higher incomes.
Inferior goods are goods for which demand decreases as consumer income increases. These goods are typically seen as lower-quality or less desirable options, and people may switch to better alternatives when they can afford them.
B. copper and iron.
C. zinc and magnesium.
D. iron and zinc.
Answer: The correct answer is iron and nickel.
Earth's core is the hottest and deepest layer. It is made of two layers The outer core which forms the border of mantle and inner core is spherical ball which is made up of metal. The outer core is about 1400 miles thick and it is made up of combination of alloys (iron and nickel). Some other metals are also found there in trace amounts like uranium, platinum and gold.In the outer core these metals are found in solid form.
The Earth's core is primarily composed of an alloy of iron and nickel. This combination is known as the "iron-nickel alloy" or sometimes referred to as "nickel-iron alloy."
The correct option is A .
In general ,The outer core is believed to be mostly liquid, while the inner core is solid, and both are predominantly made up of this iron-nickel alloy. This composition is based on scientific studies and evidence gathered from seismic waves, meteorite analysis, and other geological observations.
One key observation is the existence of primary (P) and secondary (S) seismic waves.P-waves are compressional waves that can travel through solid and liquid materials, while S-waves are shear waves that can only propagate through solid materials. By analyzing the behavior of P and S waves, scientists have determined that the Earth's core has an outer liquid layer and an inner solid layer.
Hence , A is the correct option

Answer:
0
Explanation:
In this cross, brown fur (B) is dominant to yellow fur (b).
Parent 1 has brown fur, and a genotype Bb. Parent 2 has yellow fur, and a genotype bb.
The cross is Bb x bb
B b
b Bb bb
b Bb bb
50% of the offspring are heterozygous, and have brown fur (Bb). 50% of the offspring are h0m0zygous for the recessive allele (bb). However, it is not possible for the offspring to have two dominant alleles (BB) from this cross, so the probability is 0.
