Answer:
The best and most correct answer among the choices provided by your question is the fourth choice or letter D "The thin membrane that closes the cavity of the middle ear from the outside changes position."
Your ears pop in airplanes because the air high above the surface of Earth is less dense than air near the surface, because air near the surface has all the air above it pushing down. Your inner ear has air trapped in it and as the atmospheric pressure changes, it causes pressure on your eardrum.

Material produced from living or recently living plants or animals and their metabolic byproduct is?
A) charcoal
B) biofuel
C) biomass
D) MSW
Answer:
C) biomass
Explanation:
Biomass is sustainable, and is created from creatures such as plants and animals that come from live life. Plants, wood and waste are the most common biomass materials for electricity.
They are known as feedstocks for biomass. Biomass power also can be an electricity source that is not green. Bioenergy is biomass energy or biofuel energy.

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).

Which of the following landforms is not made by groundwater erosion?
A. stalactites
B. stalagmites
C. mountains
D. sinkholes
Answer:
mountains?
Explanation:
Answer: Mountains
Explanation: Groundwater erodes rock beneath the ground surface, especially carbonate rock. Groundwater deposits material in caves to create stalactites, stalagmites, and columns. And we know that a sink whole is also known as a cenote, sink, sink-hole, swallet, swallow hole, or doline, is a depression or hole in the ground caused by some form of collapse of the surface layer. Most are caused by karst processes – the chemical dissolution of carbonate rocks or suffosion processes

What can consumers do to make sure that more materials are recycled?
А buy products made from recycled materials
00
buy biodegradable plastics
С
use canvas bags when shopping
D
use paper bags instead of plastic bags
Answer:I feel like some of the answers for me would be A and B but if you only had to choose one I would choose A
Explanation: When you buy recycled you are helping the local economy and the environment. You already know that recycling keeps useful materials from going to waste in landfills or incinerators. But did you know that buying recycled-content products ensures that markets for those recovered materials are strong
Edit: Just figured out it's not B here's why:
Plastics marketed as "biodegradable" will contribute to plastic pollution if they are lost or littered. They do not break down as quickly and completely in the environment as the term might imply and thus can harm wildlife and ecosystems. Sorry if it's long
At the time when the consumers do to make sure that more materials are recycled so here option A is considered i.e. buy products made from recycled materials.
Recycled materials:At the time when we purchase the recycled so you helped the economy as well as the environment. Also, recycling plays a vital role for minimizing the wastage and make the proper utilization of the product.
Hence, At the time when the consumers do to make sure that more materials are recycled so here option A is considered i.e. buy products made from recycled materials.

Two plants were being tested for growth. Both were given water and proper soil, etc. However, one was placed in the closet, and one was placed in the window sill. Why did the one in the closet die? Question 4 options: It was not around other plants. It was not around people enough. It did not receive sunlight. It did not have chloroplasts.
Answer:
It did not receive sunlight
Explanation:
For photosynthesis to occur, there is a chemical equation it follows
carbon dioxide + water + sunlight -> (yields) glucose + oxygen
This equation requires the sun to create glucose. The sun provides the energy for the plant to feed itself and grow.

Answer:
In the most common forms of oculocutaneous albinism, both parents must carry the albinism gene for a child to be born with the condition. Even if both parents carry the gene, the chance of each of their children being born with albinism is one in four.
