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.

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.

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.

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.

Answer:

All of it?!

Explanation:

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.

© 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).

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.

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.

Answer:

the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.

Explanation: Thats the definition of active transport or ATP

It requires energy and moves molecules against a concentration gradient. Option 1 is correct.

Active transport refers to the movement of molecules or ions across a cell membrane against their concentration gradient, requiring the expenditure of energy. Option A correctly describes active transport by highlighting the key characteristics of this process. Active transport mechanisms, such as pumps and carriers, utilize cellular energy, typically in the form of ATP, to transport molecules or ions from an area of lower concentration to an area of higher concentration. This process allows the cell to maintain concentration gradients that are necessary for various cellular functions.

Options B, C, and D describe passive transport processes. Option B describes simple diffusion, where oxygen molecules move from an area of higher concentration to an area of lower concentration without the need for energy input. Option C describes facilitated diffusion, where glucose moves down its concentration gradient with the help of specific transport proteins. Option D also describes passive diffusion, where carbon dioxide molecules move along their concentration gradient without the requirement of energy.

In summary, option A correctly describes a form of active transport by emphasizing the need for energy and the movement against a concentration gradient.
