Answer:
1.This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.
2.Humans can produce 10 of the 20 amino acids. The others must be supplied in the food. Failure to obtain enough of even 1 of the 10 essential amino acids, those that we cannot make, results in degradation of the body's proteins—muscle and so forth—to obtain the one amino acid that is needed.
3.The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place.
4.Generally speaking, we need to consume around 0.65g of protein per kg of body weight each day. However, this depends on physical activity and our general health.People who are found to have low protein in their body (hypoproteinaemia) are either not taking enough in through their diet, or are unable to absorb it. Malabsorption of food is often found in patients with gut problems, and nutritional deficiencies are often seen in chronic bowel disorders.

2. Using the classification tree shown, how would you classify an autotrophic diatom? Explain your reasoning.
Answer:
An autotrophic protist is a type of single-celled organism that can create its own food. The best-known group is the algae. Read this lesson to learn more about autotrophic protists and see some examples!
What Are Autotrophic Protists?
To answer this question, let's break it down into two parts. First, we have the term autotrophic. What does this mean? Well, an autotroph is an organism that can make its own energy, or food, typically by converting sunlight into usable components. The most common way this is done in nature is through photosynthesis. Organisms that cannot make their own energy, called heterotrophs, have to acquire energy by consuming other things.
Now we know what autotrophs are, but what are protists? A protist is a eukaryotic, microscopic organism. The term eukaryotic means the cells are organized into specific structures. A protist may be single-celled or multi-celled. Protists usually require an aquatic environment to thrive, though this may be salt or fresh water.
Characteristics and Examples of Autotrophic Protists
By knowing what each part of the name means, we already know a lot about autotrophic protists. They make their own food through the process of photosynthesis, and they are very small, eukaryotic organisms that usually live in some type of water. What else do we need to know? The largest group of autotrophic protists is collectively called algae. You have probably heard of algae before, even if you didn't know that they were classified as autotrophic protists! We can break the algae down into more specialized groups based on the shape of their cells and the type of photosynthetic pigments they use: the most common examples are green algae, red algae, brown algae, and golden algae.
Let's take a look at each of these. First, we have green algae. This type uses the pigments chlorophyll a and chlorophyll b to aid in the process of photosynthesis, resulting in the organism having a green tint in color. Green algae may be unicellular, multicellular, or live in colonies, and species use both asexual and sexual reproduction techniques.

Next, we have red algae. Unlike green algae, which comes in a variety of cellular forms, most red algae are multicellular. Like the name suggests, red algae lack certain types of chlorophyll and rely on red light wavelengths to create energy. As a result, they can live in deeper waters than the green algae (red light penetrates deeper into water than other wavelengths). Some red algae reproduce asexually by releasing spores, while others may utilize sexual reproduction.

Brown algae are different from the previous two types - they are all multicellular and can be larger in size, even visible to the naked eye. Brown algae rely on the pigment fucoxanthin in photosynthesis, and this pigment gives them their brown color. (Isn't it convenient how algae are often classified by their color?)
Put each of these animals in one of these categories.
⇒ Lacks Colored Blood
⇒has a soft, unsegmented body
⇒is a vertebrate
⇒lacks antennae

I have compared a cell to an amusement park for the assignment what part of an amusement park is similar to a mitochondria (breaks down food to make energy for cell)
you could do a boat ride! look up a picture of the cell n like make it into a boat ride. they could also be the little trains that travel around the park. hope this helped!
Answer:
The plasma membrane is like a gate and is a phospholid bilayer that surrounds the cell. The gate is much like the plasma membrane in that it selects who can enter an amusement park with a ticket. This is like the entrance to a park. The nucleus is like the information booth that contains all of the blueprints for making necessary points. At an amusement park, the information booth, much like the nucleus of a cell, provides all information and maps for where to go and what to find. The lysosome is like a recycling bin that digests excess or worn out organelles in cells. They contain digestive enzymes. In an amusement park, without trash cans, excess food and waste would have no where to be thrown away. By recycling waste, it is put through a process much like the digestive enzymes. The ribosomes are like food stands, that make proteins according to the instructions given by the DNA. Food stands in an amusement park provide nutrients and refreshments for the guests. This is much like the process of ribosomes. The rough endoplasmic reticulum are like buses. It is a series of high folded membranes that provide transport system between the nucleus and cytoplasm. In an amusement park, transportation is needed to provide guests with fast access to areas of the park. Buses provide the quickest transportation for guests.

the figures below represents two chromosomes from an animal. using the table below that describes the traits carried on chromosome #6, which trait can the animal inherit only from its mother? how do you know this?
Answer:
The Chromosomes that an organism inherits are made of 1000's of genes that are made to produce proteins that build certain traits that give the organism its characteristics. Use the diagram above to Fill in the data chart for the phases of mitosis The resulting offspring will only have half the chromosomes of the parents.

Answer:
herbivores
Explanation:
Animals that eat only plants are called herbivores (or primary consumers). Animals that eat other animals are called carnivores. Carnivores that eat herbivores are called secondary consumers, and carnivores that eat other carnivores are called tertiary consumers.
Herbivores. Animals that eat only plants are called herbivores (or primary consumers). Animals that eat other animals are called carnivores.
What are Primary consumer?Carnivores that eat herbivores are called secondary consumers, and carnivores that eat other carnivores are called tertiary consumers.
An alligator (Alligator mississippiensis) snoozes on the bank of a slow-moving water channel on a sawgrass prairie in the Florida Everglades. In the shallows, a great egret (Ardea alba) is pursuing fish. An aster leaf is being chewed by a grasshopper (Brachystola magna).
Every ecosystem has living things that work together to distribute energy in predictable ways. A trophic pyramid, as it is known among scientists, can depict these interconnections.
Therefore, Herbivores. Animals that eat only plants are called herbivores (or primary consumers). Animals that eat other animals are called carnivores.

How is the human body similar to an airplane?
Answer:
They all have different parts for it to work as a whole.
And different systems, without one of them the plane would:t work.
The human body is similar to an airplane in that; both require energy to function.
Discussion:
The airplane requires energy in form of fuel in its combustion engines. Upon combustion, the fuel is burnt and converted to energy which in turn is used to fly the airplane.The airplane requires energy in form of fuel in its combustion engines. Upon combustion, the fuel is burnt and converted to energy which in turn is used to fly the airplane.On this same note; the fuel in the human body is derived from the metabolism of nutrients in foods in a bid to convert such nutrients to the energy denomination of the human body ( ATP).
