PLS HELP!!! I WILL GIVE BRAINLY!!!!
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.

Explanation:
The picture shows the PMAT process Prophase occurs first the chromosomes become visible as paired chromatids and the nuclear envelope disappears.
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.

How are meiosis and mitosis similar?
O A. They happen at the same time.
B. They both produce new cells.
C. They both produce sex cells.
D. They both produce diploids.
Answer:
Both creates new cells
Explanation:
Meiosis and mitosis both results in the production of new cells. Therefore, the correct statement is option B.
What is meiosis?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.

There is an amusement park based on sea life. Its purpose is to get the public interested and caring about conservation of the world’s oceans. Some of the profits from this organization go toward funding ocean research and conservation. In order to get people interested, some of the shows that the park offers include large marine mammals that do tricks. Some of the larger marine animals are housed in pools for viewing instead of being allowed to live in their natural habitat. They also have rare and endangered species on display to help increase awareness of them. They even have a breeding program for the some of the endangered animals.
Describe an ethical concern that would be related to this park.
Answer:
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!

B) o movimento de rotação da lua em torno do seu próprio eixo. C) os raios solares que incidem na superfície da lua. D) a translação da lua ao redor da terra.
Answer:
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.

They are able to adapt and to live in the same environment without competing with each other. How are they able to share habitat and food resources?
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.
What do you mean by Habitat?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.

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.
