Explanation:
What is the term for an organism that makes its own source of chemical energy?
protist
B chloroplast
decomposer
D producer
Answer:
Producer
Explanation:
Chlorophast is something in a plant. Decomposers eat dead stuff and a protist is any eukaryoticorganism (that is, an organism whose cellscontains a cell nucleus) that is not an animal, plant, or fungus. So yeah. Producer. It's the only thing there that actually produces someting for its self.
The producer is the term for an organism that makes its own source of chemical energy. So the correct option is D.
What is a primary producer?
The primary producers or autotrophs are the organisms that capture their energy from sunlight or other chemical sources derived from nonliving or inorganic sources for their nutrition.
Commonly known autotrophs are Algae and higher plants. Some bacteria and protists are also important autotrophs living in running waters. The heterotrophs obtain energy and materials by consumption of living or dead organic matter.
All animals are heterotrophic organisms. Heterotrophs also include fungi, protists, and some bacteria that depend on dead organic matter for their nourishment. Usually, bacteria make the organic matter more nutrient-rich and also more accessible to other consumers.
These autotrophs and microbial heterotrophs work together to constitute the basic resources of energy that help in supporting higher trophic levels.
Therefore the correct option is D.

One of the atmospheric layers was created by living things to help keep living things alive. What is that layer?
* exosphere
*tropopause
*ozone
*thermosphere
Answer: Troposphere
Explanation: The Troposphere: The Layer in Which We Live
The lowest layer of the atmosphere, which lies next to the
Earth’s surface, is called the troposphere. The troposphere is also
the densest atmospheric layer. It contains almost 90% of the
atmosphere’s total mass! Almost all of the Earth’s carbon dioxide, water vapor, clouds, air pollution, weather, and life-forms
are in the troposphere. As shown in Figure 4, temperatures vary
greatly in the troposphere. Differences in air temperature and
density cause gases in the troposphere to mix continuously.
Answer: That would be the ozone layer.
I took the test to double check the guy above me, and Ozone seemed to be the answer.

What are grana?
please help :)
Answer:
Please Mark as Brainliest. Please!!!!!!!
Explanation:
What are Grana?
We all need photosynthesis. All of us living on Earth's surface, that is. Turning light into food energy is the foundation of almost all food chains on Earth and is the livelihood of plants and algae. These organisms house chloroplasts within their cells, organelles responsible for manufacturing energy through the process of photosynthesis. It is within chloroplasts that we find many grana.
Grana (plural of 'granum') are stacks of structures called thylakoids, which are little disks of membrane on which the light-dependent reactions of photosynthesis take place. Stacked into grana, the shape of the thylakoids allow for optimum surface area, maximizing the amount of photosynthesis that can happen.
Within the chloroplast the grana resemble stacks of green pancakes, and are not uniform in their height or distribution. The grana are connected to each other by way of lamellae, or membrane that bridge the grana but also participate in the photosystem 1 stage of photosynthesis. All parts within the chloroplast are surrounded by a liquid suspension called stroma.
Sickle cell anemia is a genetic disorder caused by recessive alleles that can cause hemoglobin molecules to
stick together. The gene for normal hemoglobin is dominant. If a hybrid man and a heterozygous woman have
a child, what is the chance that their child will have sickle cell anemia?
100%
25%
50%
0%
GREETINGS!
The sickle cell anemia allele is autosomal, meaning it can be found on one of the other 22 pairs of chromosomes, but not on the X or Y chromosome.
Hybrid trait is a heterozygous trait i.e. pair of dominant and recessive allele so that means they both man and woman are carriers, so when both the parents CARRIERS there are 25 % for children to be affected by this disorder
WHAT ARE ALL SCENERIOS FOR SICKLE CELL ANEMIA?
Scenario 1. Neither parent has the recessive sickle cell allele. None of their children will have sickle cell anemia or be carriers of the recessive allele.
Scenario 2. One parent is a carrier while the other isn’t. None of their children will have sickle cell anemia. But there’s a 50 percent chance that children will be carriers.
Scenario 3. Both parents are carriers. There’s a 25 percent chance that their children will receive two recessive alleles, causing sickle cell anemia. There’s also a 50 percent chance that they will be a carrier. Lastly, there’s also a 25 percent chance that their children won’t carry the allele at all.
Scenario 4. One parent isn’t a carrier, but the other has sickle cell anemia. None of their children will have sickle cell anemia, but they’ll all be carriers.
Scenario 5. One parent is a carrier and the other has sickle cell anemia. There’s a 50 percent chance that children will have sickle cell anemia and a 50 percent chance they’ll be carriers.
Scenario 6. Both parents have sickle cell anemia. All of their children will have sickle cell anemia.

1. Who was Henrietta Lacks? What type of disease did she die from? How long ago did she die?
Answer:
Henrietta Lacks (born Loretta Pleasant; August 1, 1920 – October 4, 1951) was an African-American woman whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line and one of the most important cell lines in medical research. An immortalized cell line reproduces indefinitely under specific conditions, and the HeLa cell line continues to be a source of invaluable medical data to the present day.
Remember that HeLa cells were grown from a tissue sample from Lacks' cervical tumor. Cancerous cells don't experience PCD, and Lacks' particular cells were especially hardy. Just like the cancer grew and spread quickly through Lacks' body, HeLa cells grow and spread quickly in vitro.
Date of death: October 4, 1951
Place of death: The Johns Hopkins Hospital, Baltimore, MD
Answer: Henrietta Lacks was an African-American woman. Her cancer cells created the HeLa cell line (most scientists call her HeLa) and that cell line was the first immortalized human cell line. She died from cervical cancer in 1951, 69 years ago.

Questien 5 (Essay Worth 4 points)
(03.02 HC)Compare and contrast open, closed, and isolated systems. Be sure
to
discuss the exchange of energy and exchange of matter, and provide at least one
example of each.
Answer:
Please mark as brainliest!!!
Explanation:
Answer;
Open system; can exchange both matter and energy; An example is a living organism such as human being, we actively interact with environment, which results in changes to both the environment and human being, for instance we eat to acquire energy.
Closed system; can exchange energy but not matter; An example is a saucepan, the saucepan allows energy transfer as the saucepan heats up and heats the contents inside it, putting a lid on it, prevents matter from entering and becomes a closed system.
Isolated system; Can exchange neither energy nor matter. For example is a thermos. if tea is poured into a thermos or an insulated container there is no exchange of heat or matter.

Lactase breaks down a sugar found in dairy products known as lactose. Some people are lactose intolerant, and this can be due to not having enough lactase production. People who are lactose intolerant may not feel well after eating foods containing lactose.
Answer:
enzyme: Lactase
substrate: Lactose
Explanation:
Identify the enzyme: Enzymes are the proteins that accelerate the rate of reaction. Enzymes are identified with the suffix - ase along with the name of the substrate. So, in the given example: the enzyme is Lactase.
Identify substrate: The substrate is defined as the molecule on which an enzyme acts. The enzyme binds with the substrate through its active site and accelerates the reaction. So, in the given example, Lactose is a substrate on which the enzyme lactase acts.
Relationship between the substrate and enzyme: When an enzyme binds its substrate, it forms an enzyme-substrate complex. The enzyme consists of an active site at which substrate binds to the enzyme and substrate causes a conformational change to enzyme resulting in enzyme-substrate complex.

Answer:
© The raccoon is an omnivore because it eats plants and animals.
Explanation:
An omnivore is an organism that obtains energy and nutrients by eating both plants and animals. Raccoons are omnivores (although often they are classified as carnivores). A raccoon can eat different types of animals such as arthropods, fish, frogs, etc, as well as plant matter (i.e., fruits and vegetables).

A team of scientists think they discovered a new organism while exploring Brazil. Upon bringing the specimen back to their lab in Atlanta, they observe the specimen for several weeks. They take a sample from the specimen to observe it under a microscope and see the sample is composed of many small compartments containing what appears to be nuclei. They shine a bright light to the left of the specimen and observe it slowly turn itself towards the light over multiple days. What further evidence would support that the newly discovered specimen is alive?
Answer:
Explanation:
Response of the organism to chemicals
when some particular chemicals are spilled when they are alive they have the ability to detect it so they either move away or closer to it. Moving further away signifies that life is in the organism and that the chemical maybe toxic to it health., some bacteria respond to chemicals
Response to touch, when there is life the organism will likely respond to touch, it can move away from the place trying to find another place to hid or stay.
