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.

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.

Answer:

B) chemoreceptors in the nose

Explanation:

Tongue helps in the tasting via the help of taste buds which are recognized and interpretation of various taste.

The nasal cavity of nose is made up of many chemo receptors where the names of the receptors are :

olfactory

vomeronasal

and trigeminal systems.

The presence of chemoreceptors in the nasal cavity is in the anterior respiratory epithelium of the nasal cavity.

Olfactory receptors that are abstractly found in the nasal cavity that is responsible for the interpretation of smell. It is the protein that is capable of binding to the odour molecules.

Then the Metaphase. The way you can remeber that s by looking at the first letter which is M. Stands for Midlle. So you can say the chromososmes are in the middle together. Now Anaphase. The way you can remember that is by looking at A meaning Away. You can think of that as the chromosomes being pulled away from each other moving opposite ways. Now last is Telophase. That when they make two nuclei. When they are divided into 2 there are not nucleus anymore but nuclei.

The animals may rely on humans for care instead of doing it themselves

Explanation:

Think about it, if the animals there don't have all the resources they need in a tank instead of the ocean. So they need the workers there to care for them. This can be bad for the animals because if they can go back to the ocean, they won't be able to get the resources they need by themselves!

C) the sun's rays that fall on the moon's surface.

Explanation:

The moon has different aspects and appearance because of the sun's rays that fall on the moon's surface. The shape of the Moon does not change itself, it occurs due to the sunlight. We only see that part of moon which is lit by the Sun. The phases of moon occur because the Sun lit different parts of the moon when the Moon revolves around the Earth so we can say that sun rays are responsible for the changing of shapes of the moon.

Answer:

In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen.

A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of greater quantities of specific antibodies that are produced in the primary response

Answer:

Both creates new cells

Explanation:

Meiosis and mitosis both results in the production of new cells. Therefore, the correct statement is option B.

Mitosis and meiosis result in cell division and the production of new cells. In mitosis, two genetically identical daughter cells are formed by a parent cell and are responsible for the asexual reproduction of organisms.

In meiosis, four daughter cells are formed from a single parent cell which is genetically diverse, and each daughter cell receives half the number of chromosomes present in the parent cell. Meiosis is the process by which gametes (sex cells) are produced in organisms, and it is responsible for the sexual reproduction of the organisms.

Therefore, both mitosis and meiosis result in the production of new cells. However, mitosis results in the production of two identical daughter cells, whereas meiosis results in the production of four genetically diverse daughter cells.

Two species of sea urchins live practically side-by-side in sandy bottoms. The two species appear to have the same diet: drift seaweeds and other bits of organic matter. They can live in the same environment without competing.

As it compels them to live in the same environmental surroundings so the characteristics of living nature also get developed as their current following situation that's helping them to get the same food & habitat.

Both species of sea urchins share the same habitat and food resources by separating their niches a little bit differently from one another.

Habitat may be defined as a type of native environment for which a particular species is best adapted due to natural selection.

Competitive exclusion leads to the elimination of any one species until they do not share different niches.

Therefore, both species of sea urchins share the same habitat and food resources by separating their niches a little bit differently from one another.

Answer:

The transfer could only occur during the day because it cannot store solar energy.

Explanation:

The transfer of electricity produced from solar energy only occurs during the day because it cannot store solar energy at a tremendous level. At homes, we can easily store the electricity made from solar energy with the help of batteries but for providing electricity to a state where thousands of houses are present, enormous batteries are needed to store it which can't be made because of very high cost so that's why the solar energy can not be stored.
