Answer:
Hydrogen disulfide
Explanation:
Hydrogen disulfide , which is responsible for the rotten-egg scent, is toxic rather than simply smelly, if inhaled at concentrations above 700 parts per million.
It can be present at very low concentrations well below those considered to induce health effects. The scent of sulfide hydrogen does not affect your well-being.

Cystic Fibrosis is an autosomal recessive disease. A carrier male is married to a carrier female. What is the chance they will have a child with cystic fibrosis?
Answer:
If only one of you is found to be a carrier, the chance that you will have a child with CF is very low, although not completely eliminated. If you are both carriers, each pregnancy will have a 1 in 4, or 25 percent chance of being affected with cystic fibrosis.

Are stars able to adapt to their environment? ANS can stars in the space respond to their changes and reproduce? Pls HELP. NEED FOR BIO
Answer:
Yes. Stars can adapt to their environment. And yes, stars can reproduce when the environment changes.
Explanation:
Answer: Stars are not living organisms. They do not reproduce. In a way, they are their own environment.
Explanation: Living organisms are made of the same "stuff" as the stars, and we depend on our star, the Sun, for energy. But the Sun can not reproduce another sun. It doesn't adapt. Forces of gravity within the galaxy and in the universe determine where stars travel, and their mass and temperature determine how long they will keep shining.

What is the function of the surface protein on the influenza virus?
Answer:
A virus surface proteins are organized to help penetrate host mucus.
Explanation:
The surface of viruses includes many copies of one type of protein that binds, or adsorbs, specifically to multiple copies of a receptor protein on a host cell.
The surface protein of influenza virus, hemagglutinin, helps the virus attach and enter host cells.
What are surface proteins?The surface protein on the influenza virus is called hemagglutinin (HA) and it plays a critical role in the virus' ability to infect host cells. HA is a glycoprotein that protrudes from the surface of the virus and binds to specific receptors on the surface of host cells, particularly in the respiratory tract.
This allows the virus to enter the host cell and hijack its machinery to replicate and produce more virus particles. The HA protein also enables the virus to evade the immune system by constantly changing its structure through a process called antigenic drift, which prevents recognition by the host's antibodies.
The importance of the HA protein makes it a prime target for the development of vaccines and antiviral drugs against influenza.

One parent has the blood type A and the other blood type B. What are the genotypes of the parents if they produce children with only blood type AB?
Human blood type is determined by co-dominant alleles. An allele is one of several different forms of genetic information that is present in our DNA at a specific location on a specific chromosome. There are three different alleles for human blood type, known as IA, IB, and i. For simplicity, we can call these alleles A (for IA), B (for IB), and O (for i).
Each of us has two ABO blood type alleles, because we each inherit one blood type allele from our biological mother and one from our biological father. A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.
How are blood types related to the six genotypes?
A blood test is used to determine whether the A and/or B characteristics are present in a blood sample. It is not possible to determine the exact genotype from a blood test result of either type A or type B. If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO.
A blood test of either type AB or type O is more informative. Someone with blood type AB must have both the A and B alleles. The genotype must be AB. Someone with blood type O has neither the A nor the B allele. The genotype must be OO.
How are ABO alleles inherited by our children?
Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).
Since there are 4 different maternal blood types and 4 different paternal blood types possible, there are 16 differnt combinations to consider when predicting the blood type of children. In the tables below, all 16 possible combinations are shown. If you know the blood type of the mother and father, the possible blood types for their children can be found.
What about the Rh factor? Can a father of blood type A+ have a child who is blood type A-?
The Rh factor genetic information is also inherited from our parents, but it is inherited independently of the ABO blood type alleles. There are 2 different alleles for the Rh factor known as Rh+ and Rh-. Someone who is "Rh positive" or "Rh+" has at least one Rh+ allele, but could have two. Their genotype could be either Rh+/Rh+ or Rh+/Rh-. Someone who Rh- has a genotype of Rh-/Rh-.
Just like the ABO alleles, each biological parent donates one of their two Rh alleles to their child. A mother who is Rh- can only pass an Rh- allele to her son or daughter. A father who is Rh+ could pass either an Rh+ or Rh- allele to his son or daughter. This couple could have Rh+ children (Rh- from mother and Rh+ from father) or Rh- children (Rh- from mother and Rh- from father).
