Answer:

Very similar DNA sequences

Explanation:

Two organisms that have related should have Very similar DNA sequences

The molecule i.e. inside cells that comprise of the genetic information and are responsible for the development and function of an organism. DNA or deoxyribonucleic acid represent the long molecule that comprise of our unique genetic code.  Nearly each & every cell in a person's body should have similar DNA. Due to this, it has the same DNA sequence.

Answer:

Monotremes, marsupials, and placentals are the three animals that could match this phylogenetic tree.

Explanation:

Monotremes, marsupials, and placentals belong from  a common ancestor. Those organisms which have one common ancestor are also called monophyletic. These animals have some changes which occurs with the passage of time but most of characters are similar to each other. In placentals animals placenta is present while in Monotremes and marsupials this placenta is absent.

Answer:

B. A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots.

A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots is most likely in Hardy-Weinberg equilibrium.

The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.

Explanation:

Examples includes the relationships between chimpanzees, gorillas and humans. It is actually believed that the chimpanzees are more closely related to humans. About 99% of ther genome is thought similar to humans while for the gorillas about 98%.

But then, it is thought that chimpanzees and gorillas should be closely related to each other than to humans, but comparison of their genomes has shown that across 15% of the gorillas genome, they share a closer relationship with humans than with chimpanzees.

Answer: Option A, C and D.

Explanation:

Cold temperature affects plants that cannot adapt to it and can eventually lead to their deaths.

If the temperature, and therefore the metabolism, remain low for an extended period, plant quality will suffer, and death may occur. A period of cold weather may also alter plant growth, as when certain vegetables “bolt,” or produce seed stalks, in response to several days at low temperatures

But maple plants in temperate region has develop some characteristics or adaptions that help its survive cold temperatures. Maple plants can tolerate frost and light freezes for short duration because they are cool plants and development characteristics to do so.

Auxins in them stimulate one final spurt before winter. Their xylems and phloems are filled with ions that prevent freezing.

They have a thick meristems which form thick scales to protect next year's buds from cold winter temperatures,

Answer:

"Protein is an important component of every cell in the body. ... Your body uses protein to build and repair tissues. You also use protein to make enzymes, hormones, and other body chemicals. Protein is an important building block of bones, muscles, cartilage, skin, and blood."

"They must be consumed in the diet. Everyone needs 8 of these amino acids: isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Infants also need a 9th one, histidine.

The percentage of protein the body can use to synthesize essential amino acids varies from protein to protein. The body can use 100% of the protein in egg and a high percentage of the proteins in milk and meats. The body can use a little less than half of the protein in most vegetables and cereals.

The body needs protein to maintain and replace tissues and to function and grow. Protein is not usually used for energy. However, if the body is not getting enough calories from other nutrients or from the fat stored in the body, protein is used for energy. If more protein is consumed than is needed, the body breaks the protein down and stores its components as fat.

The body contains large amounts of protein. Protein, the main building block in the body, is the primary component of most cells. For example, muscle, connective tissues, and skin are all built of protein.

Adults need to eat about 60 grams of protein per day (0.8 grams per kilogram of weight or 10 to 15% of total calories). Adults who are trying to build muscle need slightly more. Children also need more because they are growing. People who are limiting calories to lose weight typically need a higher amount of protein to prevent loss of muscle while they are losing weight. "

Explanation:

The two statements that correctly represent the analogies are as follows:

Thus, the correct options are C and D.

An Analogy may be defined as the condition of comparing two things in order to reveal the identical function of each other. It makes the process of understanding more clear and effective.

The engine of the car is analogous to the digestive of the human. This is because it provides the energy for other parts to function properly.

The exhaust system of the car is analogous to the excretory system of the human. This is because it removes all the waste material out of the car in the form of smoke, dust, etc.

Therefore, the correct options for this question are C and D.

Answer:

Precambrian era is the longest era in the Earth's history.  It began 4600 million years ago and ended about 540 million years ago.

Explanation:

Precambrian era makes up the vast majority of Earth's history. So, the correct option is D.

The majority of the history of the planet occurs during the Precambrian epoch. The Precambrian, which occurs before the current Phanerozoic Aeon, is the earliest period in Earth's history. The Cambrian, the earliest period of the Phanerozoic Aeon, is named after Cambria, the Latinized name for Wales, where rocks of this era were first investigated, hence the name "Precambrian."

The Precambrian period is known as the "Age of Early Life." The Precambrian period saw the formation of continents, the emergence of our current atmosphere, and the evolution and flourishing of early life. The world's oceans were home to soft-bodied animals like worms and jellyfish, while the land remained sterile.

Therefore, the correct option is D.
