Answer:
In many mammals, a developing embryo is nourished through the placenta. ____ is a connection with the mother. Later, a newborn takes in food produced by the blood artilleries of the mother. Unlike a young mammal, an insect or amphibian undergoes metamorphosis which is a series of dramatic changes in body shape and form.
In many mammals, the placenta, which connects the mother and the embryo, provides nutrition to the growing embryo. Oxygen and nutrients can be exchanged between the mother and foetus thanks to the placenta.
What is the mode of nourishment of an infant ?The infant then consumes nourishment made by the mother's milk. This milk, which the mother's mammary glands make, is nutrient- and antibody-rich and aids the infant's growth and development.
An insect or an amphibian goes through metamorphosis, which is a sequence of significant changes in body structure and form, unlike a newborn mammal. The insect or amphibian completely changes during metamorphosis from a larva or tadpole to an adult form the rearrangement of tissues and cells.
The bug or amphibian's adult form can reproduce and is adapted to its environment. Hormones are what cause this metamorphosis, and it requires.

What is a similarity between the temperate climate zone and polar climate zone?
A) Both of the climate zones have warm and hot weather and lots of precipitation.
B) In both polar and temperate zones, the temperature of the warmest month is about 18°C.
C) The temperature can get to 0°C in both temperate and polar climate zones.
D) The temperate and polar climate zones both usually have 150 cm of precipitation.
In both the polar and temperate zones, the temperature of the warmest month is about 18°C. So, the correct option is B.
What are Polar and Temperate zones?Temperate regions are defined as regions with mild temperatures that lie between the subtropical and polar regions where the two regions between the Tropic of Capricorn and the Antarctic Circle or the Tropic of Cancer and the Arctic Circle are called temperate regions.
The polar region is defined as the area around the North Pole or the South Pole, where the North Polar Region consists mainly of flotation and pack ice, 7–10 feet (2–3 m) thick which floats on the Arctic Ocean and is surrounded by land. In both zones, the temperature of the warmest month is about 18°C.
Therefore, the correct option is B.

of Conservation of Mass?
A. when rocks are deposited in layers, the oldest layer is on the bottom
B. pressure from a gas increases as the volume decreases
C. energy can neither be created nor destroyed
D, the force of gravity decreases as distance is increased
Answer:
C. energy can neither be created nor destroyed
Explanation:
The law of conservation of mass states that in a chemical reaction mass can neither be created nor destroyed. Similarly, the law of conservation of energy states that the amount of energy in an isolated system is conserved ie. the amount of energy can neither be created nor destroyed, but instead changes form.
Nuclear reactors do not create energy, instead they convert

The relationship between the termite and bacteria is called mutualism.
What is mutualism?Mutualism is the kind of relationship between two organisms in which both organisms benefit from one another.
According to this question, termite stomachs contain bacteria that digest the fiber in wood for the termites. In turn, the bacteria are provided with a hospitable environment to carry out their life processes.
This means that both the termite and bacteria are benefitting from the relationship, hence, is a type of mutualism.

The relationship described between termites and the bacteria in their stomachs is an example of mutualism. So, the correct option is B.
What is Mutualism?A symbiotic relationship in which both organisms benefit from the interaction is known as mutualism. In this example, the bacteria give the termites the ability to digest the fiber in wood, which they are unable to digest on their own, in return for the bacteria providing the termites a hospitable environment to live and carry out their life activities.
A specific type of mutualism known as "symbiosis," in which the species involved live in close association with one another for extended periods of time, as illustrated by the termite-bacteria mutualism. These kinds of mutualistic connections are prevalent in nature and can involve a wide range of creatures, including microbes, plants, and insects.

Which of the following are pieces of evidence showing common ancestry among species?
Answer:
1. The pieces of evidence that support the theory of evolution include the following:
a. Fossil records/evidence
b. DNA of the organisms
c. Comparative anatomy
2. Whales have features that are similar to land mammals, such as the presence of hip bones and the need to breathe air. In this case, the whale fossils indicate that the modern whales that we see today have evolved from the land-dwelling mammals that existed 50 to 70 million years ago.
3. According to Darwin’s theory of evolution through the process of natural selection, the presence of a trait that is observed throughout the timeline of divergence of species is used as evidence that supports the idea that certain organisms share common ancestors.
In this case, comparative anatomy can provide the scientists the evidence that the organisms which share anatomical or structural similarities have common ancestry; hence, supporting the theory of evolution.

Moving a book to a lower shelf decreases potential energy.
True
False
Answer:
True
Explanation:
Moving a book so the potential energy of the system decreases is a true statement.
What is potential energy?A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.
A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.
Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.
Therefore moving the book to a lower shell change potential energy, which decreases.

Even though mutations are relatively rare, they are still a concern in bacteria populations. Why?
Answer:
Mutations can provide resistance to antibiotics If we were to treat the bacterial population with that specific antibiotic, only the resistant bacteria will be able to multiply; the antibiotic selects for them. These bacteria can now increase in numbers and the end result is a population of mainly resistant bacteria.
Explanation:
Even though mutation is rare in bacteria, it is still important to be concerned about bacteria. The reason is that if any mutation happens that converts the bacteria into antibiotic-resistant bacteria, then this would be harmful.
What is mutation?Mutation is a phenomenon in which a change is seen in an organism's genome. It may be induced by chemical factors, environmental factors, etc. The mutation may be positive or negative.
In a population, evolution is seen due to mutation. It is one of the factors behind evolution. In bacteria, the mutation happens too. If any sort of mutation happens that makes them antibiotic-resistant, then it would be harmful for humans. Humans take antibiotics that destroy harmful bacteria. If these bacteria mutate their genetic constitution and become resistant, a higher dose of antibiotic will be required next time to destroy such harmful bacteria.
Hence, mutations in bacteria are harmful even though they are rare.

Why are there many, many more craters on the "outer back" side of the moon than there are on the "inner facing" side of the moon?
Answer: Due to the strong force of attraction of external objects like meteorites or rocks the outer surface of the moon is affected by the craters.
Explanation:
The asteroids, meteorites, comets, and other space bodies fly around the moon and when they hit the surface of the moon a crater is created as the moon has no atmosphere. Also, the size of the crater is larger than that of the size of the body. The inner surface of the moon also has a crater which is because of volcanic eruptions occurring inside the moon. The volcanic craters are the same as that of the impact so produced. The volcanic eruptions are not much frequent than the exterior objects hitting the moon so more craters are created on the outer backside of the moon.
