Mammalia are animals that belong to the class Mammalia. Mammals are one of the most evolved vertebrate species in the animal kingdom.
They are found all over the world and have adapted well to their surroundings, which include oceans, deserts, and polar regions, as well as rainforests and rivers. Let us take a closer look at the characteristics and classifications of the Mammalia class of animals.
Classification of mammals
1. Mammals are warm-blooded creatures that give birth to their young.
2. They are the most common type of animal found in almost all habitats.
3. They have mammary glands, which aid in the production of milk to feed their young.
4. The presence of a brain region known as the Neocortex
5. Their skin contains oil glands (sebaceous glands) as well as sweat glands sudoriferous glands).
6. The fur of hair that covers the body and aids animals in adapting to their surroundings.
7. They are heterodont, which means they have different types of teeth.

In the carbon cycle, several processes contribute to the movement of carbon through the ecosystem. For each of the types of movement below, name the process in the carbon cycle that accomplishes it: A. Movement of carbon from the atmosphere into living organisms: ___________________ B. Movement of carbon from living organisms into the atmosphere: ___________________ C. Movement of carbon between different organisms due to feeding: ____________________
Answer:
A. Movement of carbon from the atmosphere into living organisms: PHOTOSYNTHESIS
B. Movement of carbon from living organisms into the atmosphere: RESPIRATION.
C. Movement of carbon between different organisms due to feeding: DECOMPOSITION
Explanation:
Carbon is the main element in the compounds that make up living organisms. It is found in the remains of living organisms, fossil fuels, inorganic salts, water bodies and air. It is continuously being removed from and added to the carbondioxide in the atmosphere.
The CARBON CYCLE is defined as the process which brings about the circulation of carbon compounds in nature. These processes include:
--> PHOTOSYNTHESIS: Green plants (producers) are continuously removing carbon dioxide from the atmosphere for photosynthesis. The carbon of the carbon dioxide is incorporated into sugars and other complex organic compounds in plants' tissues. When the plants are eaten by animals (primary consumers), the plant material is digested, absorbed and built up into compounds which form animal tissues. Thus, this accomplishes movement of carbon between different organisms due to feeding.
--> RESPIRATION: Plants and animals respire all the time to obtain energy. During this process, sugar are broken down to liberate carbondioxide and water as wastes. Thus this accomplishes the movement of carbon from living organisms back into the atmosphere.
--> DECOMPOSITION: This is a process in carbon cycle where decomposers feed on the dead and decaying organisms and their excreta and bring about their decomposition. They have enzymes that break down organic compounds into simple inorganic compounds. Although inorganic compounds (carbondioxide) are released during decay, decomposers absorb these compounds for their own use. When decomposers doe, othe decomposers feed on them thereby accomplishing the movement of carbon between different organisms due to feeding.

Its about bio and its confusing
Answer:
a) the process of mitosis generates new cells that are genetically identical to each other. mitosis helps organisms grow in size and repair damaged tissue. some species of alge are capable of growing very quickly.
b) more growth occurs in the root tips and very little new cell development occurs in woody stems after they are formed
c) sequential order means put things in order.
A B C D E
Hello again, Bakere!
a) Mitosis, the dividing of a single cell into two daughter cells, is a way for the plant to stay healthy-looking and strong. All cells die eventually, and they must be replaced by new, fresh ones. This replacement occurs through mitosis. Mitosis also allows the plant to grow, as mitosis is found more frequently in growing areas than ones that are finished growing. Since mitosis makes more cells, you will find much more mitosis occurring in a new shoot than in an old tree, because the old tree doesn't need a bunch of new cells to continue growing.
b) Mitosis is more frequent on the outside of the root because new cells are needed constantly as multitudes of them are scrubbed away by rough dirt. On the inside of the root, however, there is little to no exposure to harsh soil erosion. Because of this, mitosis is needed less here - only to replace the dying cells.
c) The order for the letters should be: A, E, D, B, C. I'm including a picture to help you understand why. :)

What is Mutagen?Mutagen may be characterized as a type of agent that possesses the capability to induce mutation within the genetic segment of living organisms. Mutagens are of two types, they are:
Physical mutagens: UV radiations.Chemical mutagens: Chemicals like ethidium bromide.According to the context of this question, mutation can only be inherited from parent to offspring, if it is induced within the gamete cells of parents. While during the course of life, the mutation also induces in the genomic sequence of an individual.
Therefore, the correct options for this question are A, D, and E.

Write a poem about symbiotic relationships. It must include Commensalism Mutualism, Parasitism, Competition, and Predation.
Answer:
Explanation about Commensalism Mutualism, Parasitism, Competition, and Predation are given below.
Explanation:
There are various symbiotic relationship formed between the organisms present in the environment. These relationships are Commensalism Mutualism, Parasitism, Competition, and Predation. In Commensalism relationship, one organisms gets benefits while the other neither get benefit nor harm. In mutualism, both organisms gets benefits from one another. In Parasitism, one organism get benefits and the other get harmed. In Competition, both organisms cause harm to one another and both are damaged through their actions and in Predation, one organism is benefited by killing the other organism to feed itself.

A scientist is studying trace fossils of an early mammal. Which type of informatin can be learned from studying
trace fossils?
how many teeth the mammal had
the structure of the mammal's skeleton
information about the behavior of the mammal
how the mammal is related to modern mammals
Answer:
Studying the trace fossils allows scientists to determine how the animal moved, whether it traveled alone or in groups, the environment in which it lived in, an organisms feeding habits or nesting behavior, and their feces, known as profiteroles, can provide information about an organism's diet.
Explanation:
hope it helps
The environment in which the organism lived, its feeding habits or nesting behavior, and their feces, known as profiteroles, can reveal information about an organism's nutrition are all things that can be learned through studying trace fossils.
What types of information do we get from trace fossils?Instead of the preserved remnants of the actual animal's body, trace fossils offer us indirect proof of life in the past in the form of animal footprints, tracks, burrows, borings, and feces.What information can scientists gain from trace fossils?Paleontologists can learn about the activity of ancient species by studying trace fossils. For instance, studying dinosaur footprints has greatly improved our knowledge of their behavior.What are two types of trace fossils?The majority of known trace fossils come from marine strata. There are basically two different kinds of traces: exogenic traces, which are created on the sediment's surface (like tracks), and endogenic traces, which are created within the sediment's layers (such as burrows).

describe how oxygen and carbon dioxide are cycled using the cardiovascular and respiratory system
Answer:
respiratory system fills the blood with oxygen and gets rid of the carbon dioxide while the cardiovascular system umps the oxygen rich blood all over the body (short answer)
Explanation:
the respiratory system aids in the supply of oxygen to the blood and the exit of carbon dioxide. when the heart takes in blood that is short of oxygen and full of carbon dioxide, the pulmonary arteries pumps the blood to the lungs, who then fill the low oxygen blood with oxygen and transport the carbon dioxide out of the lungs. this oxygen rich blood, which now has a rich amount of hemoglobin, is transported to the heart which is pumped or circulated it to the entire body.

Distinguish between Diet and Nutrition
Answer:
Diet is limiting oneself in foods and calories for several days or weeks. As a result, overweight is rapidly leaving, but once you return to your previous lifestyle, as extra pounds return, and getting rid of them becomes more difficult.
Proper nutrition is a complete balanced everyday diet, in which all necessary products must be present: meat, cereals, dairy products, fruits, vegetables. Eating healthy and balanced all the time not only strengthens the body but also helps to lose weight. It is known that an organism that does not regularly receive all the necessary substances begins to "junk".

[tex]\huge{\mathbb{\tt { What \: is \: Diet?}}}[/tex]
In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons. Although humans are omnivores, each culture and each person holds some food preferences or some food taboos.[tex]\huge{\mathbb{\tt { What \: is \: Nutrition?}}}[/tex]
Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It includes ingestion, absorption, assimilation, biosynthesis, catabolism and excretion. The science that studies the physiological process of nutrition is called nutritional science.[tex]{\boxed{\boxed{\tt { Difference \: between \: Diet \: and \: Nutrition}}}}[/tex]
The main way of getting nutrition is by having a proper diet. Diet comprises of different foods, which contain nutrients. When the foods are ingested, nutrients are absorbed by the body. Body uses them in different metabolic activities. A poor diet will result in a poor metabolic efficiency. Finally, it may lead to nutrient disorders or unbalance nutritional conditions in human body.#CarryOnLearning
