Answer 1

Carbon dating is an example of a practical application of proving or disproving theories.

Carbon dating :

Carbon dating is now used to date almost everything that is over 100 years old. It is accepted as fact and used as evidence to learn about the world and past civilizations. Carbon dating, on the other hand, is at best a good theory, and that is all it is. Many people overlook the definition of a theory.

What is carbon dating based on?

The basic premise of radiocarbon dating is straightforward: all living things absorb carbon from their surroundings, including a small amount of naturally radioactive carbon-14. When a plant or animal dies, it no longer absorbs, but the radioactive carbon it has accumulated continues to decay.

Why did the Rocky Planets form closer to the Sun than the Gas Giants?

Answers

Answer: High Temperatures from the sun

Explanation:

Due to the high temperatures radiating from the sun, only materials that had high melting points could survive around it as opposed to those with low melting points that became vaporized into gas. These materials with higher temperatures were then pulled by the gravity of the sun and kept colliding till they formed the inner planets closest to the sun being Mercury, Venus, Earth and Mars.

The other materials that were with low melting points which became gas spread to the outer part of the solar system and as they became ice, they came together and formed cores with gravities that pulled other gases till they formed the gas giants as we know them today.

Two patients are in a hospital. One has retrograde amnesia and the other has anterograde amnesia. Explain one similarity and one difference between the two types of amnesias. Then predict how these two patients will interact with each other.

(i already know what each amnesia means i just mostly need the 'predict how these two patients will interact with each other' because its confusing to me)

Answers

Answer:

One similarity between retrograde and anterograde amnesia is that they both involve memory impairment. Retrograde amnesia is the inability to recall memories that occurred before the onset of amnesia, while anterograde amnesia is the inability to form new memories after the onset of amnesia.

One difference between the two types of amnesia is the direction of the memory impairment. Retrograde amnesia affects memories that were already stored before the onset of amnesia, while anterograde amnesia affects the formation of new memories after the onset of amnesia.

Given their different types of amnesia, it's unlikely that the two patients will be able to fully understand each other's memory difficulties. The patient with retrograde amnesia may have difficulty remembering events from their past, while the patient with anterograde amnesia may struggle to form new memories. Depending on the severity of their amnesia, the patients may have trouble communicating with each other and forming new memories together. However, their interactions may still be meaningful and they may form a bond based on their shared experiences of memory impairment.

1 What does the codon sequence on the mRNA strand determine?
A The gene sequence of the DNA
B The amino acid sequence of the polypeptide
C The codon that is signaled
D The signaling sequence

2 What portion of the DNA is also known as a gene?
A The coding sections
B The non-coding sections
C The mRNA strand
D The polypeptide sequence

Answers

1. The correct answer is B.

2. The correct answer is A.

The codon sequence on the mRNA strand determines the amino acid sequence of the polypeptide.

The coding section is the portion of the DNA that is also known as a gene. Genes are the functional units of DNA that provide the instructions for making proteins. They are composed of coding cells, also known as exons, that contain the information needed to build the polypeptide, and non-coding sections, also known as introns, that do not.

The codon sequence on the mRNA strand is translated by the ribosome during protein synthesis. Each codon, which is a sequence of three nucleotides, corresponds to a specific amino acid. The ribosome reads the codon sequence on the mRNA strand and adds the corresponding amino acids to the growing polypeptide chain. This process is called translation.

In DNA, genetic information is encoded in the sequence of nucleotides, which are the building blocks of DNA. Genes are specific segments of DNA that contain the instructions for making a specific protein. These instructions are encoded in the sequence of nucleotides within the coding sections of the DNA, also known as exons. The non-coding sections, also known as introns, do not contain instructions for making proteins, but they play important roles in the regulation of gene expression.

To determine if aerobic respiration has taken place in the bottle, several tests can be done to detect the presence of certain products and byproducts of the process. Here are some possible pieces of evidence that aerobic respiration has taken place in the bottle:

Carbon dioxide production: Aerobic respiration produces carbon dioxide as a byproduct, so if there is an increase in the concentration of carbon dioxide in the bottle, it can indicate that aerobic respiration has taken place.

Oxygen consumption: Aerobic respiration requires oxygen as a reactant, so if there is a decrease in the concentration of oxygen in the bottle, it can indicate that aerobic respiration has taken place.

Which of the following does not yield wool ? (a) yak (b) camel (c) goat (d) woolly dog​

Answers

Answer: (D) Woolly dog

Explanation:

Why is option A (yak) not correct?

The Himalayan region is home to the yak, a type of cattle. They have a reputation for having long, shaggy hair, which is used to create many different textiles, including wool. Yak wool is popular because it is soft, warm, and long-lasting and is frequently used to manufacture clothes and blankets.

Why is option B (camel) not correct?

Camels are widely known for their capacity to survive in difficult desert situations, and their wool is a valuable resource in many parts of the world. Clothing, rugs, and other textiles are frequently made from camel wool because it is cosy and soft.

Why is option C (goat) not correct?

Goats are another typical source of wool, especially in warmer locations where other types of wool are less common. Depending on the breed of goat and the quality of the wool, the term "mohair" or "cashmere" is frequently used to describe the wool from goats. Cashmere is appreciated for its warmth and luxurious feel, while mohair is renowned for its softness, sheen, and insulating qualities.

Why is Option D (woolly dog) correct?

Despite the fact that there are numerous dog breeds with long, shaggy hair, none of them actually produce true wool. Dog hair is not often used to produce textiles since it is formed of a different kind of fibre than wool. Although some dog hair can be spun into yarn and used for crafts, it is not regarded as a true wool and is not widely utilised for the manufacturing of textiles.

what is the life cycle for a goldfish?​

Answers

Answer:

The life cycle of a goldfish starts out as an egg. The female fish will lay about 25 eggs, but unfortunately only some grow up. The eggs usually hatch within 5 days and if you have a fish tank then you should take the adult fish out or else it may eat the eggs. After the egg hatches, it turns into a fry,(this is what a baby goldfish is called) Once they hatch, they will stay attached to the plants for two days, after that, you should start to feed them. Once they are not fry anymore, they turn into adult goldfish. If you take care of them properly, they could last up to 15 years! Once the fish are complete adults, they can lay eggs. The females rub up against plants and lays eggs while the male Goldfish sprays the eggs to make them fertilize and turn into fry.

This graph shows the effects of an enzyme on a particular reaction.

Answers

It is safe to infer from the graph depicting how the enzyme effected the reaction that the enzyme had an impact on the reactants' activation energy.

Define enzyme.

When compared to the reaction with the enzyme indicated by the blue line, the reaction without the enzyme shown by the red line revealed that the reactants had a larger activation energy.

Enzymes actually work by reducing the activation energy, also known as the energy needed to be overcome by reactants in order to become products.

Define activation energy.

The smallest additional amount of energy that a reactive molecule needs in order to transform into a product is known as activation energy. The minimal amount of energy required to activate or energies molecules or atoms so that they can engage in a chemical reaction or transformation is another way to put it.

Which condition causes transpiration to INCREASE?

lower humidity
no air movement
colder temperatures
high soll moisture​

Answers

High soil moisture causes transpiration to increase by increasing the water potential of the plant, increasing the relative humidity of the atmosphere, and increasing the turgor pressure of the plant cells. Here high soil moisture is the correct answer.

Transpiration is the loss of water vapour from the surfaces of a plant or a leaf. A condition that causes transpiration to increase is high soil moisture. Plants get water from the soil through their roots. High soil moisture increases the water content of the soil and the water potential of the plant. The water potential of the plant is the measure of the pressure required to extract water from the plant. High soil moisture reduces the water potential gradient between the soil and the plant.

The high soil moisture creates a favourable condition for transpiration because it increases the relative humidity of the atmosphere around the plant. Transpiration occurs because the air surrounding the leaf is drier than the air inside the leaf. When the relative humidity of the atmosphere is high, the rate of transpiration increases.

The high soil moisture also increases the turgor pressure of the plant cells. Turgor pressure is the pressure that water exerts on the cell wall of the plant. The turgor pressure is what keeps the plant cells rigid. When the turgor pressure is high, the rate of transpiration increases. Therefore high soil moisture is the correct answer.
